THE PSYCHOLOGY OF THE NEGRO-
AN EXPERIMENTAL STUDY
CHAPTER I
REVIEW OF WORK PREVIOUSLY DONE
Interest in the psychology of the negro has produced a
voluminous Hterature, but the knowledge to be obtained from
a reading of it is not commensurately extensive. It may be
not unjustly said that until what is practically the present
time our information as to the negro's intellectual character-
istics has been almost wholly a product of varying individual
opinion and speculation. Here and there have appeared works
of value, based upon study and experience and presenting
carefully drawn conclusions. But for the most part the litera-
ture consists of articles which have grown out of limited and
untrustworthy observation, and of articles which have attacked
the problem from the standpoint of preconceived theories and
have reached conclusions a priori from the premises thus held.
There has been no settled body of doctrine concerning the
vastly important matter of the mental capacity of the negro.
One man has held that the negro is the equal of the white in
intellect; another has held that a great intellectual gulf sep-
arates the two races. And there have been many varieties of
views between these two extremes. There have been no facts
agreed upon and consequently no reliable generalizations. Yet
social practices of far-reaching importance have been based
upon these varying views. Some school systems have advo-
cated giving precisely the same training to precisely the same
racial minds; other systems have advocated a differentiation
of school work to meet the needs of two mentally different
races ; the advocates of both views have put their beliefs into
2 THE PSYCHOLOGY OF THE NEGRO.
practice. Many social and political considerations have of
course had their bearing upon these educational matters, but
certainly ideas as to the nature of the mind of the negro have
not been without influence. And the social and political con-
siderations themselves have had a psychological background.
In the last few years a number of objective studies of the
intellect of the negro have been made, and they constitute a
definite step toward a scientific answer to the vexed question
upon which they bear. It is the purpose of the present chapter
to review the experimental work which has been done in this
limited field of race psychology and also some of that which
has not been experimental. In the following chapters will
be set forth the results of an objective study which it is hoped
will contribute in some measure toward an answer to the
problem.
Non-Experimental Studies
In discussing "human faculty as determined by race,"
Boas, in an early article ('94), the substance of which is in-
corporated in a later work ('11), pointed out that while the
skull capacity of modern European whites is 1560 cc. and that
of European whites of the neolithic period is the same, the
skull capacity of the mongaloid race is 1510 cc, that of the
negroes of the Pacific ocean is 1460 cc. and that of African
negroes is 1405 cc. The negroes, too, were at least as tall
as Europeans. Another way of putting it is to say that while
50 per cent, of whites have skull capacities of 1560 cc, only 27
per cent, of negroes equal or exceed this skull capacity.
Further, "We find that the face of the negro as compared
to the skull is larger than that of the American, whose face
is in turn larger than that of the white. The lower portion
of the face assumes larger dimensions. The aveolar arch is
pushed forward and thus gains an appearance which reminds
us of the higher apes. There is no denying that this feature
is a most constant character of the black races and that it rep-
resents a type slightly nearer the animal than the European
type." ('94,p. 311). "Our conclusion is, that there are differ-
ences between the physical characters of races which make
it probable that there may be differences in faculty. No un-
questionable fact, however, has been found yet which would
prove beyond a doubt that it will be impossible for certain
races to attain a higher civilization." ('94, p. 317).
In a later article ('01, p. 3), Boas argues as follows: "A
REVIEW OF WORK PREVIOUSLY DONE. 3
number of anatomical facts point to the conclusion that the
races of Africa, Australia and Melanasia are to a certain extent
inferior to the races of Asia, America and Europe. We find
that on the average the size of the brain of the negroid races
is less than the size of the brain of other races, and the differ-
ence in favor of the Mongaloid and white races is so great
that we are justified in assuming a certain correlation be-
tween their mental ability and the increased size of their
brains. At the same time it must be borne in mind that the
variability of the mongaloid and white races on the one hand,
and of the negroid races on the other, is so great that only
a small number, comparatively speaking, of the individuals
belonging to the latter have brains smaller than any brains
found among the former; and that, on the other hand, only a
few individuals of the mongaloid races have brains so large
that they would not occur at all among the black races. That
is to say, the bulk of the two groups of races have brains of
the same capacities, but individuals with heavy brains are
proportionately more frequent among the mongaloid and white
races than among the negroid races. Probably this differ-
ence in size of the brain is accompanied by differences in
structure, although no satisfactory information on this point
is available."
Boas then takes up the argumpnts that primitive races
cannot abstract, inhibit impulses or choose according to
standards of value. His contention is that primitive man does
do tnese things, but that he does them from his own pomt
of view and to meet his own needs, and not in the same way
that civilized man does them. Similarly with the argument
that while a savage can perceive well in a sensory way, he
cannot interpret phenomena: he does interpret phenomena,
but from his own point of view, as is the case with all men.
"Our considerations make it probable that the wide differences
between the manifestations of the human mind in various
stages of culture may be due almost entirely to the form of
individual experience, which is determined by the geographical
and social environment of the individual. It would seem that,
in the different races, the organization of the mind is on the
whole alike, and that the varieties of mind found in different
races do not exceed, perhaps not even reach, the amount of
normal individual variation in each race." ('01, p. 11).
A radically different opinion from that of Boas is held by
4 ', THE PSYCHOLOGY OF THE NEGRO.
Le Bon. ('98). This author holds that the human race may
be divided into four groups on the basis of psychological char-
acteristics: (1) Primitive races, such as the Fuegians and
the aboriginal Australians, (2) Inferior races, such as the
negroes, (3) Average races, such as the Chinese, Japanese,
Mongolians and Semitic peoples, (4) Superior races, which
are the Indo-Europeans. "No confusion is possible between
the four great divisions we have just enumerated. The men-
tal abyss that separates them is evident." ('98, p. 28) . The
specific differences which separate the primitive and inferior
peoples from those which are higher are that the former races
have a relative incapacity to reason or associate, to com-
pare and draw conclusions, to attend, observe and reflect, to
exercise foresight, to persist in a given line of activity, to hold
to a distant rather than a present end. These differences are
practically ineradicable, and they determine the achievement
of the races. "The various elements of the civilization of a
people being only the outward signs of its mental constitution,
the expression of certain modes of feeling and thinking peculiar
to a people, these elements cannot be transmitted unchanged
to peoples of a different mental constitution: all that can be
transmitted is the exterior, superficial, and unimportant
forms." ('98, p. 233).
Races of men also differ in the relative size of their brains,
according to Le Bon. From measurements of the volume of
several thousand skulls, he concludes that the differences are
real, though not very considerable. And he further draws
the interesting conclusion that the more civilized races display
a much greater divergence from their average brain size than
do the races which are backward. Thus the higher races
have more very large and very small brains than primitive
people, relatively to their average; the brains of the inferior
races conform more nearly to their average type.
Tylor writes ('04, pp. 74-75) : "There seems to be in man-
kind inbred temperament and inbred capacity of mind
In measuring the minds of the lower races, a good test is how
far their children are able to take a civilized education. The
account generally given by European teachers who have had
the children of lower races in their schools is that, though
they often learn as well as the white children up to about
twelve years old, they then fall off, and are left behind by
the children of the ruhng race. This fits with what anatomy
REVIEW OF WORK PREVIOUSLY DONE. 5
teaches of the less developed brain in the Australian and Afri-
can than in the European. It agrees also with what the his-
tory of civilization teaches, that up to a certain point savages
and barbarians are like what our ancestors were and our
peasants still are, but from this common level the superior
intellect of the progressive races has raised their nations to
heights of culture."
"Moreover, there is this plain difference between low and
high races of men, that the dull-minded barbarian has not
power of thought enough to come up to the civilized man's
best moral standard Much of the wrong-doing of the
world comes from want of imagination The lower
races of men are so wanting in foresight to resist passion and
temptation, that the moral balance of a tribe easily goes
wrong, while they are rough and wantonly cruel through
want of intelligent sympathy with the sufferings of others,
much as children are cruel to animals through not being able
to imagine what the creatures feel." ('04, pp. 407-408).
In discussing racial brain differences Tylor says : "Professor
Flower gives as a mean estimate of the contents of skulls,
Australian, seventy-nine; African, eighty-five; European,
ninety-one. Eminent anatomists also think that the brain of
the European is somewhat more complex in its convolutions
than the brain of a Negro or Hottentot. Thus, though these
observations are far from perfect, they show a connection
between a more full and intricate system of brain-cells and
fibres, and a higher intellectual power, in the races which have
risen in the scale of civilization.
"It is often possible to tell by inspection of a skull what
race it belongs to. The narrow cranium of the negro would
not be mistaken for the broad cranium of the Samoyed
Taking the diameter from back to front as 100, the cross-
diameter gives the so-called index of breadth, which is about
70 in the Negro, 80 in the European, and 85 in the Samoyed.
The Austrahan and African are prognathous or "forward
jawed,' while the European is orthognathous, or 'upright-
jawed.' At the same time the Australian and African have
more retreating foreheads than the European, to the disadvan-
tage of the frontal lobes of their brain as compared with ours."
('04, pp. 60-62).
G. Stanley Hall's view of the relative mental make-up of
the negro and the white may be set forth in the following
6 THE PSYCHOLOGY OF THE NEGRO.
quotations : "No two races in history, taken as a whole, differ
so much in their traits, both physical and psychic, as the
Caucasian and the African. The color of the skin and the
crookedness of the hair are only the outward signs of many
far deeper differences, including cranial and thoracic capacity,
proportions of body, nervous system, glands and secretions,
vita sexualis, food, temperament, disposition, character,
longevity, instincts, customs, emotional traits and diseases.
All these differences, as they are coming to be better under-
stood, are seen to be so great as to qualify if not imperil every
inference from one race to another, whether theoretical or
practical, so that what is true and good for one is often false
and bad for the other." ('05, p. 358).
"Another racial trait of the negro is found in the sphere
of sexual development. Special studies show that the negro
child up to about twelve is quite as bright as the white child ;
but when this instinct develops it is earlier, more sudden,
and far more likely permanently to retard mental and moral
growth than in the white who shoots ahead. Thus the virtues
and defects of the negro through life remain largely those of
puberty." ('05, p. 362).
This last contention of Hall's, that the negro's develop-
ment comes to what is at least a partial stand-still at puberty,
occurs in the writings of others who have dealt with the sub-
ject. Tylor has already been quoted on this point. The idea
is that after puberty the individual's mental life broadens and
takes on new aspects: abstraction, a tendency to penetrate
into the meanings of things, the power to perceive relations,
and the ability to appreciate logical, aesthetic and moral situa-
tions. Before adolescence a child's activities are mainly the
so-called lower mental processes, such as perception, memory
and the motor responses. The negro, being the lower type,
fails to attain the post-pubertal traits to the degree that the
white child attains them, and therefore remains permanently
on a lower level. But on this level, and in the traits which
constitute it, he is fully the equal of the white child. Thus,
while he cannot reach the finer elements of mental attain-
ment, the negro is yet the equal or the superior of the white
in sense capacity, rote memory, objective attentiveness, motor
control, and qualities of a similar nature. Another statement
from Hall bears upon this : "Mental development after puberty
is much more uncertain than before. The first twelve years
REVIEW OF WORK PREVIOUSLY DONE. 7
of life represent larger and more fundamental qualities.
Adolescence adds a new story, less stable, very liable to arrest
at any stage This makes nearly the whole post-pubic
period critical, peculiarly exposed to dangers from without,
because it is so plastic and susceptible, and still more so be-
cause the growth forces that push youth on toward maturity
are so liable to show signs of exhaustion before their work is
finished. Hence it follows that length of the growing period
is one of the most important factors in development. Lower
races often stop short when sexual maturity is achieved."
('03, p. 811.) In this connection, Libby ('08), reporting the
result of an experiment in which he had white high school
and grammar grade pupils write compositions descriptive of
a certain sentimental picture, states that the feeling, meaning
and sentiment of the picture were grasped only by pupils older
than fourteen years. And Ellison, as reported by Bagley ('09),
says that children below the age of thirteen do not have
abstract ideas such as would enable them to give good defini-
tions.
Odum ('10, pp. 36-37) agrees with the general idea repre-
sented in the last two quotations from Hall: "Negro children
are easily interested, attentive, eager and alert. For the most
part they are bright and learn easily. In many cases they ap-
pear brighter than white children of the same age. They
learn from memory easily and retain little things for some
length of time They learn readily to do things by
imitation and become comparatively skilful in a short time.
.... However, there are many negro children who have an
almost total lack of mental perception, whose minds are so
dense that they can scarcely learn anything. The percentage
of such cases increases with age." This author makes many
statements, without, however, giving evidence to substantiate
them, to the effect that the negro child, as shown by experi-
ments, is brightest — i. e., most able to do and learn simple
things — at thirteen years of age, and that he is of greatest
ability — i. e., most able to "grasp and hold that which con-
fronts the mind" — at eight or nine years of age; that the
negro's mental development practically ceases at the age of
about thirteen ; that there is an almost entire absence of sexual
morality among the great body of negroes, children and adults,
due to the predominance of their "physical impulses and
pleasure-pain feelings ;" that the more primal emotions, fear,
8 THE PSYCHOLOGY OF THE NEGRO.
anger, jealousy, self-exaltation, self -depreciation, sorrow, etc.,
are especially active in the negro ; that dynamically the negro
is volatile, easily responsive to stimuli, guided by present im-
pulses, unrestrained — in short, that his life is one of temporary
emotion rather than of permanent sentiment.
A recent article by Bardin ('13) argues that there must
be a connection between racial mental differences and the
physical differences between races, since both were evolved
together. And since it is becoming increasingly evident that
the negro and the white differ mentally, we must therefore
suppose that there are corresponding neural differences, as
marked, in their way, as are the external physical signs of race,
such as skin, hair texture and facial angle. From this posi-
tion the writer contends that in attempting to modify the
negro's mind while yet keeping him a physical negro we are
undertaking the impossible. "It follows, therefore, that pres-
ent ideals in regard to the solution of our Negro problem
are biologically fallacious, and impossible of attainment. We
can never make the Negro like the white man mentally. We
can never have a bi-racial state based upon an identity of
ideas and political philosophies in both races." ('13, p. 374).
This contention is almost identical with that quoted above
from Le Bon.
One of the most interesting estimates of the intelligence
of the negro was made by Francis Galton ('92). In a study
of the relative capacity of the white and negro races he divided
each race into sixteen defined grades of ability, eight above
and eight below its racial average, and considered that the
intervals separating the grades were equal throughout. After
a survey of eminent men of each race he came to the conclu-
sion that the ablest negro ranked two grades below the ablest
white. Then, by an application of the "law of deviation from
an average," he held that negroes as a race have two degrees
of ability less than Europeans. Another way of expressing it
is to say that the difference between negroes and whites
in intellectual capacity is about one-eighth of the difference
between the most eminent man and the lowest idiot. Galton
then goes on to point out that the experiences of travelers
among native tribes and the prevalence among negroes of
feeble intellects furnish confirmation of his estimate.
After a survey of the available evidence of racial mental
differences, Thomdike ('10, pp. 67-68) sums up as follows:
REVIEW OF WORK PREVIOUSLY DONE. tf
"From all these facts each student may make his own esti-
mate of the original mental differences of races, and learn at
least the need of more actual measurements of race differences
and of intelligence in interpreting them. My own estimate is
that greater differences will be found in the case of the so-
called 'higher' traits, such as the capacity to associate and to
analyze, thinking with parts or elements, and originality, than
in the case of the sensory and sensori-motor traits, but that
there will still be very great overlapping. Calling the differ-
ence between the original capacity of the lowest congenital
idiot and that of the average modern European 100, I should
expect the average deviation of one pure race from another
in original capacity to be below 10 and above 1, and the differ-
ence between the central tendencies of the most and the least
gifted races to be below 50 and above 10. I should consider
3 and 25 as reasonable guesses for the two differences."
Experimental Studies
From these studies and opinions of a non-experimental
nature we may turn to those which are based upon quantita-
tive investigation. The first attempt at a quantitative study
of the negro with which the writer is familiar is that by Bache,
published in 1895. This investigator starts with the assump-
tion that the more inferior the race, the quicker the reaction
time. "That the negro is, in the truest sense, a race inferior
to that of the white can be proved by many facts, and among
them by the quickness of his automatic movements as com-
pared with those of the white." ('95, p. 481). The results
of the tests on twelve whites, eleven Indians and ten negroes
showed the whites to be the slowest and the Indians to be the
quickest with auditory, visual and electrical stimulation. The
speed of the negroes was roughly midway between that of the
Indians and the whites. The writer explains that the reason
the negroes were slower than the Indians was that they were
of mixed white and negro blood and had inherited the effects
of slavery, while the Indians' mode of life compelled them to
rely upon quick movement. This explanation is offered to
strengthen the writer's contention that the Indian is a higher
race than the negro, and consequently should have a slower re-
action time. The study is hardly conclusive; the numbers
tested were too small, and the variabilities of the average re-
10 THE PSYCHOLOGY OF THE NEGRO.
action times are not given. Certainly the initial assumption
was not proved by the tests.
Smith made some association and memory tests upon a
"typical" negro boy sixteen years of age. The nature of the
tests is not given, nor are the results set forth. The author's
general conclusion, plainly unwarranted on the basis of the
work done, is as follows: "The negro child is psychologically
different from the white child. In automatic power he is
superior, but in the power of abstraction, of judgment and
analysis he is decidedly inferior. This fact must be recognized
in the school training." ('96, p. 60).
Stetson ('97) gave a memory test to five hundred white
and five hundred colored children in the fourth and fifth grades
of the schools of Washington, D. C. The average age of the
white children was 11 years; the average age of the colored
children was 12.57 years. The test was somewhat crude. It
consisted in reading to the children four verses of four lines
each, explanations of the verses being given and the class re-
peating them twice in concert. Later the verses were repro-
duced orally to the experimenter by each child, and the repro-
ductions were scored as being 100, 75, 50, or 25 per cent, cor-
rect. The results showed that the negroes were superior to
the whites in memory of three of the verses, while the whites
were superior in memory of one. The average score for the
four verses was: Whites, 58.09; Colored, 58.27. In other
words, there was practically no difference in memory capacity
between the two races. But in school studies the average
rank of the white children was 74.32, while the average rank
of the colored was 64.73. This superiority of the whites in
school work led the author to conclude that the negroes were
deficient in reasoning power, since the test showed that they
were not deficient in memory. This conclusion, of course, is
subject to criticism on the ground that a number of other fac-
tors may have been responsible for the academic inferiority
of the colored children.
McDonald studied 91 colored children by means of physical
and mental tests. His conclusions are summarized as fol-
lows: "Among the boys and girls the per cent, of long heads
is much greater after puberty than before. This is also true
of white boys but not of white girls. The colored boys are
more sensitive to heat and locality after puberty than before.
The reverse is true with the white boys, but the colored girls,
REVIEW OF WORK PREVIOUSLY DONE. H
like the white girls, are less sensitive after puberty
Colored children are much more sensitive to heat than white
children Colored girls have larger circumference of
head at all ages than white girls White children, rela-
tively to their height, are longer bodied than colored children.
The percentage of long-headedness among colored boys is more
than double that of white boys." ('99, pp. 1141-1143). The
writer states that from a table based on teachers' estimates
of the brightness, dullness and mediocrity of colored children,
(number indefinite), it appears that the percentage of bright
children, both boys and girls, increases rapidly between the
ages of seven and eight, and continues to increase slightly
until the age of thirteen. From thirteen to sixteen the per-
centage of bright pupils decreases rapidly. It would seem
that the results of this work should be verified by other inves-
tigators before being accepted. The chances for error in the
mental tests used are considerable, and the composition of
the various groups tested is not quite clear.
The foregoing experimental studies, all of which were
made prior to 1900, emphasize the need of a careful technique
in the quantitative handling of this question. The opportuni-
ties for error are very great, and in inexperienced hands
psychological tests and statistical methods may lead to results
that are worse than useless. A field as little worked and as
inviting as this of the comparative psychology of the white and
the negro is likely to attract, and has attracted, investigators
who lack the necessary training— just as it has attracted theo-
rists who were not adequately grounded in the essentials of
their work. One would not be far wrong in saying that all of
the experimental work done on the psychology of the negro
prior to 1900 is of practically negative value.
In summarizing the status of scientific race psychology
in 1910, Woodworth writes as follows:* "One thing the
psychologist can assert with no fear of error. Starting from
the various mental processes which are recognized in his text-
books, he can assert that each of these processes is within
the capabilities of every group of mankind Statements
to the contrary, denying to the savage powers of reasoning,

or abstraction, or inhibition, or foresight, can be dismissed at
once. If the savage dilf ers in these respects from the civilized
man, the difference is one of degree, and consistent with over-
lapping of savage and civilized individuals." ('10, pp. 3-4).
Woodworth then goes on to discuss the evidence in regard
to the several sense capacities. Natives of Brazil, the steppe-
dwelling Kalmucks, Papuans, Indians, Filipinos and other races
have been tested for visual acuity, and found, on the whole,
to have vision superior to that of the average white, but the
overlapping between the whites and these races is great.
"We may perhaps conclude that eyesight is a function which
varies somewhat in efficiency with difference of race, though
with much overlapping It did not seem possible, how-
ever, to assert anything like a correspondence between eye-
sight and the degree of primitiveness or backwardness of a
people Even if small differences do exist, it is fairly
certain that the wonderful feats of distant vision ascribed
to savages are due to practice in interpreting slight indications
of familiar objects." ('10, pp. 5-6). In the case of hearing,
the tests indicate that whites are superior to primitive peoples.
This superiority may be due in part to the fact that the ears
of civilized man are better protected from injuries than are
those of savages, and that the meatus is kept cleaner by the
white man. Then, too, the white is more familiar with the
sorts of sound used in the tests than is the savage, and on this
account may detect them more readily. The few tests that
have been made for keenness of smell show no higher acuity
among negroes and Papuans than among Europeans. In ability
to discriminate two points on the skin the evidence is conflict-
ing ; on the whole there is probably no appreciable superiority
in favor of any of the races tested. The experiments which
have been made to determine the acuity of the pain sense are
largely vitiated by the fact that savages and civilized men
have different standards as to what constitutes pain. "On the
whole," says Woodworth, "the keenness of the senses seems
to be about on a par in the various races of mankind."
('10, p. 7). In reaction time, speed of tapping and suscepti-
bility to illusions, the tests seem to indicate that the different
races are about equal.
In discussing tests for intelligence as opposed to sensory
and motor capacity, the writer points out that the form-board
is the only test of intelligence which has been used with differ-

ent races. 'This test was tried on representatives of several
races, and considerable differences appeared. As between
whites, Indians, Eskimos, Ainus, Filipinos and Singhalese, the
average differences were small, and much overlapping occurred.
As between these groups, however, and the Igorot and Negrito
from the Philippines and a few reputed Pygmies from the
Congo, the average differences were great and the overlapping
was small. Another rather similar test for intelligence which
was tried on some of these groups, gave them the same rela-
tive rank. The results of the test agreed closely with the
general impression left on the minds of the experimenters by
considerable association with the people tested. And, finally,
the relative size of the cranium, as indicated, roughly, by the
product of its three external dimensions, agreed closely in
these groups with their appearance in intelligence and with
their standing in the form test. If the results could be taken
at their face value, they would indicate differences of intelli-
gence between races, giving such groups as the Pygmy and
Negrito a low station as compared with most of mankind."
('10, pp. 10-11).
One of the important investigations of the mental
capacity of the negro is that by Mayo ('13), who studied the
school marks of 150 white and 150 colored high school pupils
in the schools of New York City. His results can best be
given in his own words : "To summarize, the following are the
leading results deduced from the data considered:
"The median age of white pupils at the time of entering
high school in the city of New York is 14 years 6 months ; of
colored pupils 15 years 1 month — a difference of 7 months.
The average deviation for whites is 9 months ; for colored, 15
months. Twenty-seven per cent, of the whites are as old as the
median age of the colored or older.
"Colored pupils remain in school a greater length of time
than do the whites. For the cases studied, the average time
spent in high school for white pupils was 3.8 terms ; for col-
ored, 4.5 terms. About 28 per cent, of the whites attain the
average time of attendance for the colored.
"Considering the entire scholastic record, the median mark
of the 150 white pupils is 66 ; of the 150 colored pupils 62 ; a
difference of 4 per cent. The average deviation of white pupils
is 7 ; of the colored 6.5. Twenty-nine per cent, of the colored
pupils reach or surpass the median mark of whites.
14 THE PSYCHOLOGY OF THE NEGRO.
"The white pupils have a higher average standing in all
subjects The percentage of colored pupils reaching
the median mark of the whites in the several subjects is as
follows : Modern languages, 33 ; mathematics, 32 ; history, 31 ;
the sciences, 29; Latin and Greek, 27; English, 24; the com-
mercial subjects, 22; and all subjects together, 29.
"The total number of subjects pursued by the white group
was 2433; the total number of subjects passed on the first
trial was 1855; the percentage of subjects passed being 76.
The total number of subjects pursued by the colored group
was 2382; the total number of subjects passed on first trial
was 1379, the percentage of subjects passed being 58. Inter-
preting these figures as a measure of relative scholastic
efficiency, the efficiency of colored subjects is 76 per cent, of
that of the whites ; that is, the colored pupils are about % as
efficient as the whites in the pursuit of high school studies."
('13, pp. 44-45).
These results are significant as they stand, and they be-
come still more so when it is considered that the colored pupils
studied were, as Mayo points out, a more closely selected group
than the whites. How much more closely the negroes were
selected than the whites is not known. It must also be borne
in mind that the colored group was not made up of persons
of pure negro blood. The percentage of mulattoes is not
stated, but it is probably high. And the presence of mulattoes
considerably raises the standard of negro attainment, as will
be shown in a later chapter. Another consideration tending
to emphasize the racial differences found by Mayo is that the
colored pupils with whom he dealt were for the most part
either emigrants from the South or the children of emigrants,
and that they therefore probably inherited the ability and
energy which leads the ambitious negro to seek to better his
condition in the North. On the other hand, it is difficult to
estimate the white group represented in this study. It con-
tained English, Germans, Irish, Italians and Jews in indefinite
numbers, but a random selection of whites was carefully ob-
served, and the group is probably typical of the white high
school population of New York.
Phillips ('12), in a study of retardation in the public ele-
mentary schools of Philadelphia, found percentages of re-
tardation as follows in schools attended entirely by colored
pupils: 68.2, 60.6, 67.3, 70.9, 66.3, 72.8, 58.2, 59.3. The per-
REVIEW OF WORK PREVIOUSLY DONE. 15
centages of retardation in the respective school districts in
which these eight schools were situated were as follows: 41.8,
44.5, 45.1, 45.1, 37.2, 36.0, 36.0, 33.3. In other words, the per-
centage of retardation in the colored schools ranged from 72.8
to 58.2, while the percentage of retardation in the districts
which contained these schools ranged from 45.1 to 33.3. The
average percentage of retardation for the city as a whole was
40.3. Each of the colored schools had a greater percentage
of retardation than any of the white schools, even those com-
posed almost entirely of foreigners, and in those schools at-
tended by both white and colored pupils the percentage of re-
tardation on the whole varied directly with the percentage of
colored pupils in attendance. The writer concludes by saying :
"It is a question whether the course of study is suited to the
negroes, as the educational results are so far behind those in
the other schools, and it is very doubtful whether even a
liberal interpretation of the course of study would meet the
educational necessities of this group." ('12, p. 90).
In a later article ('14), Phillips reports the results of an
attempt to ascertain the causes of this retardation by means
of an application of the Binet tests to white and colored chil-
dren of the same chronological age and home conditions, the
tests being made in all cases by the same individual. "Forty
colored girls and 46 colored boys, totaling 86, were tested by
the Binet scale ; 75 white girls and 62 white boys, totaUng 137,
were likewise tested. The home of each of these 223 pupils
was visited and the home conditions noted, as Excellent, Good,
Fair and Poor. In so rating the home, the material (money) ,
intellectual, and moral elements were noted in making up the
rating. In the following comparison only the white children
of excellent home conditions are compared with the colored
children of excellent home conditions ; the white of good home
conditions with the colored of good home conditions, and so on.
This method of procedure, of course, necessitated the elimina-
tion of quite a number of those tested, so that our final com-
parison was made on 29 each of colored boys and girls re-
spectively." ('14, p. 191).
The results are stated as follows : " . . . . we see that of
those tested 37.9 per cent, of the white boys were retarded,
while 65.5 per cent, of the colored boys were retarded; that
46.4 per cent, of the white girls were retarded and 71.4 per
cent, of the colored girls were retarded ; and that 42.1 per cent.
16 THE PSYCHOLOGY OF THE NEGRO.
of the white boys and girls combined were retarded, and that
68.4 per cent, of the colored boys and girls combined were re-
tarded. This makes the colored boys retarded 17.4 (27.6)*
per cent, more than the white boys ; the colored girls retarded
25 per cent, more than the white girls; while the total rate
of retardation of both groups is 26.3 per cent.
" we find that 31 per cent, of the colored girls (boys)t
are accelerated while 62 per cent, of the white girls (boys)t
are accelerated; that 28.5 of the colored boys (girls) f are
accelerated and 53.5 per cent, of the white boys (girls) ;t and
that 29.8 per cent, of colored boys and girls are accelerated
and 57.8 per cent, of both white girls and boys. This makes a
difference in the acceleration between the two races of 31 per
cent, in favor of the white boys, 25 per cent, in favor of the
white girls, 28 per cent, in favor of the white pupils with boys
and girls combined.
"This would seem to corroborate the findings in the case of
pedagogic retardation. We see in every group, considering the
retardation from pedagogical or psychological viewpoints, that
the colored pupils are retarded from 20 to 30 per cent, more
than the white pupils, and that the white pupils are always
greatly above them in acceleration." ('14, pp. 191-195).
It is interesting to note that the total number of pupils
tested, including those eliminated on account of not having
comparable home conditions, gives practically the same com-
parative result as was obtained from the picked group. The
percentage of retarded pupils in the total colored group was
54.6; the percentage of retarded pupils in the total white
group was 24. The percentage of accelerated pupils in the
total colored group was 6.9; in the total white group it was
20.4.
The author concludes as follows: "In applying the Binet
tests to colored children the following facts of interest were
fortunately thrust upon our attention. In the first place
the colored pupils as a class were good in the memory tests
and poor in those requiring judgment. They were generally
*This figure should evidently be 27.6 instead of 17.4. It represents
the difference between the percentages of retardation of white and col-
ored boys, which are 65.5 and 37.9, as quoted, and also as given in the
tables which accompany the article.

slower in response. The testing of the colored children took
a much longer time than the white. Their reaction time was
greater, they were less animated. It is significant to note
that the younger white children were more advanced than the
colored children of the same age. This is in contradiction
to the generally accepted fact that colored children are quicker
when young.
"If the Binet tests are at all a gauge of mentality it must
follow that there is a difference in mentality between the col-
ored and the white children, and this raises the question:
Should the two groups be instructed under the same cur-
riculum?" ('14, p. 196).
The first application of the Binet tests to whites and ne-
groes was made by Strong, and was reported by her ('13) and
by Morse ('14). Two hundred and twenty-five white and
125 colored children were tested in the schools of Columbia,
S. C. The percentage of children testing more than one year
below age was 10.2 for the white and 29.4 for the colored.
The percentage testing more than one year above age was
5.3 for the white and 0.8 for the colored. The largest group
of white children was that testing at age; the largest group
of colored children was that testing one year below age.
An attempt was made to divide the white children into
"city children" and "mill children," in order to arrive at a
conclusion as to how far inferiority in the tests was due to
poor environment. The environment of the mill children is
of considerably lower grade than that of the city children, and
is not markedly different from that of the negroes. When
this division was made the results showed that 6 per cent, of
the city children were more than one year below age while 18
per cent, of the mill children were more than one year back-
ward. On the face of it, then, this would indicate that the
comparatively poor showing made by the negroes was in large
measure due to poor home conditions. But in fact it leaves
the question still open. For while mill children may have ad-
verse environment, they may also have poor native capacity
due to their poor heredity. Their unfavorable surroundings
may be the product of a lack of inheritable capacity in their
parents.
This criticism applies to all attempts to determine the in-
fluence of environment upon people whose heredity is not
known to be alike. And yet such efforts are made with
18 THE PSYCHOLOGY OF THE NEGRO.
seemingly increasing frequency. It should be remembered
that poor achievement, in psychological tests or in any other
activity, may be accompanied by inferior social condition and
yet not be the product of that condition. The achievement
and the condition may both result from one and same cause,
lack of native capacity. In such matters as are sought by
all, such as the ordinary facilities of life and intercourse accord-
ing to the prevailing standards, it is very probable that native
capacity determines the relative attainment of men within
any large and homogeneous unit of mankind. And it is very
probable that the presence of poor home environment among
any considerable group of our population is due to a compara-
tive absence of ability in that group as a whole. This ab-
sence is inherited by the offspring of that group. Errors due
to a neglect of this consideration need to be especially guarded
against in psychological investigations which aim to study
environmental influence.
Strong divided the negroes tested by her into classes
on the basis of degree of skin pigmentation. She says: "The
children were divided into three groups according to color.
This classification was not a scientific one, and the statement
of results may be entirely worthless. There were 34 dark
children, 35 medium in color, and 43 light colored in this
classification, 122 in all. Of the dark colored, 14.4 per cent,
tested below age, 76.7 per cent, tested at age, and 8.8 above
age. Of the next group, somewhat lighter in color, 31.1 per
cent, tested below age, 62.2 at age, and 6.6 per cent, above age.
Of the lightest group 44.2 tested below age, 44.2 at age, and
11.6 above age. The darkest children are more nearly normal,
the lightest show the greatest variation, both above and below
normal." ('13, p. 506).
Morse comments upon the tests as follows: "In general it
may be said that the colored children excel in rote memory,
e.g., in counting, repeating digits (but not one was able to re-
peat 26 syllables), naming words, making rhymes and in time
orientation. They are inferior to the whites, however, in
aesthetic judgment, observation, reasoning, motor control,
logical memory, use of words, resistance to suggestion and in
orientation or adjustment to the institutions and complexities
of civilized society." ('14, p. 78). With reference to peda-
gogical retardation, he writes : " according to the Binet
scale, a larger number of white children are in a school grade
REVIEW OF WORK PREVIOUSLY DONE. 19
below their mental ability than above, whereas the reverse is
true of the colored children." ('14, p. 78).
In reviewing this study, Bruner says: "The tables show
another interesting point on which the author makes no com-
ment. At the ages of six, seven and eight just about twice
as many negro children as white rate below age, whereas for
the ages of ten, eleven and twelve the superiority of the whites
over the negroes is but slight. This suggests that the rate
of maturing may be more rapid with the negro children, so
as to make them older, mentally, at the age of twelve than
white children of the same age." ('14, p. 385).
A study of the learning capacity of whites and negroes
was made by Baldwin ('13). A somewhat elaborate substi-
tution test was used five minutes a day for sixteen days with
37 white and 30 colored delinquent adolescent girls. Their
ages ranged from 13 to 21 years. "Fourteen other negro
girls were too feeble mentally to perform the tests after the
initial instructions although they worked assiduously for the
period of three weeks, and three white girls failed to do 50
per cent, of the work correctly." ('13, p. 317). From the
summary of the results: "In this type of learning it is found
that: 1. Comparing the amount of work done by the thirty-
seven white girls with the work done by the thirty negroes
who accomplished more than 50 per cent, of correct results,
it is evident that the negroes are decidedly inferior. The
white girls made 72.3 substitutions as a general average, the
negroes 55.8. The negroes accomplished 62.4 per cent, as
much work as the white girls and made 245.3 per cent, as
many errors. Practically all the superior negroes in the school
were included in the test.
"2. The learning capacity of delinquent negro girls differs
quantitatively and qualitatively from that of the white girls,
and the educational corollary follows that different methods
of instruction and training are required for the negro girls
than for the white girls." ('13, pp. 331-332) .
On the whole the inferiority of the negroes was about the
same in both absolute amount of work done and in learning
capacity. The negroes as compared with the whites were
slow to warm up, quick to lose interest, difficult to stimulate
except through flattery, irregular, moody, vacillating in atten-
tion, inaccurate, envious of each other's progress, given to
20 THE PSYCHOLOGY OF THE NEGRO.
mumbling, grumbling, humming, saying funny things while
at work.
A study of this kind is difficult to evaluate in its bearing
upon normal subjects. The girls were all committed to an
institution as delinquents, and their mental ability was proba-
bly considerably below the average. Whether both races
were equally below the average is not known. The fact that
fourteen negro girls could not work the test at all, while only
three white girls failed to complete as much as 50 per cent,
of the work, would indicate that the negroes were farther
below the average racial ability than were the whites; but
this is not conclusive. That the test failed to enlist the in-
terest of the colored girls indicates that their true learning
ability was not measured. But this, too, is of doubtful sig-
nificance, since the very fact that the negroes were not inter-
ested as were the whites possibly points to a deficiency in the
colored group. On the whole, it seems safe to say that the
test is probably indicative of a true racial difference, though
the amount of such difference is left uncertain.
Since the tests to be described in the following chapters
were made, there has appeared a preliminary report by Pyle
('15) of an extensive investigation of the relative mental
capacity of whites and negroes. This investigator tested 408
colored pupils, from eight to sixteen years of age, inclusive,
in the public schools of Columbia, Mexico and Moberly, three
towns in Missouri, using a number of standard tests, and com-
pared the results thus obtained with the norms which he had
previously ascertained for white children in the same tests.
As the report which has so far appeared is only preliminary,
it is impossible to go into detail concerning the work done, but
the author's words may be quoted to indicate the main out-
lines of this valuable research:
"The following are the conclusions to which the work so
far points In general the marks indicating the men-
tal ability of the negro are about two-thirds those of the
whites. The negro girls approach the white girls in ability
a little more closely than the negro boys approach white
boys. Negro boys and girls are farther apart in ability than
are white boys and girls. In both races the girls are superior,
if the average performance is taken as the basis of compari-
son. With increasing age, there is a tendency for the differ-
ence between whites and negroes to become less. This ten-

dency is more marked with boys than with girls. About one-
fifth of the negroes are equal or superior to the average
of the whites, while three-fourths of the whites are equal or
superior to the average of the negroes. In the same school
grade, the negroes are several months older than the whites.
Negro girls have the best permanent memory for ideas in the
eleventh year. The same is true of white girls. Negro boys
have the best permanent memory for ideas in the twelfth
year and white boys in the thirteenth year. In rote memory
the negroes have a much better memory for concrete than
for abstract words, but are greatly inferior to whites in both.
"If, for purpose of comparison, the negroes are sep-
arated into two groups according to social position, it is
found that the negro boys of better social class have about
four-fifths of the ability of white boys. The negro girls of
better social position have an ability which is about three-
fourths that of white girls. Difference in social position has
less effect on negro girls than on negro boys. The difference
in social position has most effect on tests requiring quickness
in learning, quickness in controlled association, in immediate
and permanent logical memory and in constructive imagina-
tion as measured by the Ebbinghaus test. With negro chil-
dren of the better social class the tendency to approach the
florm of white children is more marked. In the substitution,
controlled association and Ebbinghaus tests, the negroes are
less than half as good as whites. In free association and
the ink-blot tests they are nearly as good. In quickness of
perception and discrimination and in reaction, the negroes
equal or excel the whites.
"At all ages, the physical development both in muscular
strength and muscular speed is nearly the same for negro
boys and white boys. The same is true for negro girls and
white girls until the age of ten. After ten, negro girls are
stronger than white girls, but white girls are faster. The
negro girls are stronger probably because they do more mus-
cular work than white girls do. Muscular speed seems to be
little affected by conditions of life while muscular strength
is much affected by them.
"Perhaps the most important question that arises in con-
nection with the results of these mental tests is this : How far
is ability to pass them dependent upon environmental condi-
tions? Our tests show certain specific differences between
22 THE PSYCHOLOGY OF THE NEGRO.
negroes and whites. What these differences would have been
had the negroes been subject to the same environmental in-
fluences as had the whites, it is difficult to say. The results
obtained by separating the negroes into two social groups
would lead one to think that the conditions of life under which
the negroes live might account for the lower mentality of the
negroes. On the other hand, it may be that the negroes
living under the better social conditions are of better stock.
They may have more white blood in them." ('15, pp. 357-
360).
Neurological Studies
It is assumed everywhere as a matter of course that men-
tal differences imply neural differences. If there are mental
differences between two races, then we may expect to find
differences in the nature of the brain structure of the two
races, and vice versa. The comment is frequently made that
apparent differences in the size or shape of the brains of
given racial groups must indicate corresponding psychical
divergencies. Such comment has been quoted in some of the
foregoing abstracts, notably in those from Boas, Le Bon and
Tylor. If there is a racial, or individual, inheritance of mind
there must be an inheritance of appropriate anatomy and
physiology.
A few recent investigators have attacked this problem of
racial neural differences. In Baltimore, Bean studied the
brains of 103 negroes and 49 Caucasians. He concludes that,
"Not only is the anterior association center smaller in the
Negro than in the Caucasian, but the whole frontal lobe of
the Negro is smaller." ('06, p. 374). The negro stands in
an intermediate position between man and ourang in the rela-
tive size of his frontal to his parietal and occipital lobes.
Bean then goes on to point out that this conclusion is in
accord with well-known traits of the negro. He states, citing
Flechsig as authority, that the anterior association center,
which is comparatively small in the negro, is intimately con-
nected with ideas regarding personality ; the relations of self,
subjectively and objectively; the capacity for ethical and
aesthetic judgment; self-control, especially in such matters as
sexual excitement, anger or vexation; will power. The pos-
terior association center, on the other hand, which is com-
paratively large in the negro, is more intimately connected
REVIEW OF WORK PREVIOUSLY DONE. 23
with the special senses; it is objective and concrete, while the
anterior center is subjective and abstract in the mental
processes which its operation accompanies. "The relative
differences found in the association centers of the two races is
suggestive in relation to the known characteristics of the
two, in view of Flechsig's work. The Caucasian i« subjective,
the Negro objective. The Caucasian .... is dominant and
domineering, and possessed primarily with determination, will-
power, self-control, self-government, and all the attributes of
the subjective self, with a high development of the ethical and
aesthetic faculties. The Negro is in direct contrast by reason
of a certain lack of these powers, and a great development
of the objective qualities. The negro is primarily affectionate,
immensely emotional, then sensual and under stimulation
passionate. There is love of ostentation, of outward show, of
approbation ; there is love of music, and capacity for melodious
articulation; there is undeveloped artistic power and taste
— Negroes make good artisans, handicraftsmen — and
there is instability of character incident to lack of self-control,
especially in connection with the sexual relations ; and there is
lack of orientation, or recognition of position and condition of
self and environment, evidenced by a peculiar bumptiousness,
so-called, that is particularly noticeable. One would naturally
expect some such character for the Negro, because the whole
posterior part of the brain is large, and the whole anterior
portion small, this being especially true in regard to the
anterior and posterior association centers." ('06, pp. 378-
379).
Further, Bean reports that he found the ratio of the corpus
callosum to the total brain weight to be greater in the Cau-
casian than in the negro, the anterior end of the corpus cal-
losum in the whites being relatively large when compared
with its posterior end.
In weight, the 51 negro brains, male, averaged 1292 grams,
while the 37 white male brains averaged 1341 grams; the 28
female negro brains averaged 1108 grams, while the 9 white
female brains averaged 1103 grams. The negroes were of a
higher class than the whites, however, and mulattoes were
included among them.
These conclusions of Bean's are very interesting, but they
seem to need further confirmation before they can be ac-
cepted as final. Following Bean, Mall ('09) found no such
24 THE PSYCHOLOGY OF THE NEGRO.
definite racial differences. He states that the brain weight
of eminent men is 100 grams above that of men in general,
and that the average white man has a brain 100 grams heavier
than that of the average negro. But the frontal lobe as com-
pared with the rest of the brain has the same relative weight
in both negroes and whites, male and female. And the con-
figuration of negro and white brains is the same. " with
the present crude methods the statement that the negro brain
approaches the foetal or simian brain more than does the
white is entirely unwarranted." ('09, p. 20). "It certainly
would be important if it could be shown that the complexity
of the gyri and sulci of the brain varied with the intelligence
of the individual, that of the genius being most complex, but
the facts do not bear this out, and such statements are only
misleading brains rich in gyri and sulci, of the Gauss
type, are by no means rare in the American negro." ('09,
p. 24).
This investigator reviews the previous work done in this
field, and comes to the final conclusion that there is no valid
evidence to show significant brain differences from the point
of view of race, sex or genius.
Karl Pearson ('07), after a study of the heads of 1000
Cambridge graduates and 5000 school children, states that his
results corroborate the conclusions of previous articles, and
sets forth his findings as follows: "The average correlation
between head length or head breadth and intelligence is .11.
.... no sensible modification is made in this result if allow-
ance be made for either weight or stature." But "some 44
per cent, of very able men have heads smaller than the aver-
age slow man and some 44 per cent, of slow men heads larger
than the average specially able man. This order of numerical
relationship holds for the whole range of the characters dealt
with, and in view of it we see how idle it is to assert that head
measurements can be of any service in the prediction of in-
telligence Differences in size of head will not account
for at most 1/12, and probably not as much as 1/20, of the
observed differences of capacity whether between adults or be-
tween children." ('07, p. 121).
Hrdlicka ('98) investigated the physical differences be-
tween 1100 white and 300 negro children, and found that
the negro's forehead is narrower but not lower than that of
whites, and that the negro's head is unusually long and nar-

row, while the heads of whites are of all shapes. He says
the negroes' ears are smaller, their arms, hands and feet
longer, and their chest somewhat deeper than is the case
among white children. The weight of white children at all
ages is somewhat greater than that of negroes, but the negroes
at all ages and of both sexes are three or four pounds stronger
with each hand.
Hrdlicka also finds, as did Le Bon in the abstract previ-
ously given, that the variation among the whites is greater
than among the negroes. "The white children show more
diversity, the negro children more uniformity in their normal
physical characters. This fact becomes gradually more
marked as we advance with the age of the children." ('98,
p. 476).
it is impossible to make an adequate summary of the
views set forth in this chapter ; the abstracts given are them-
selves summaries. But it is clear that by far the greater num-
ber of writers who have dealt with the problem of the rela-
tive mental ability of the white and the negro take the view
that the negro is inferior. This is particularly true of those
investigators who have used quantitative methods. The
negro has not shown the same capacity as the white when
put to the test of psychological or educational experiment, and
the racial differences revealed have been considerable. In the
higher mental processes that go to make up the capacities
necessary to a successful conduct of civilized life, the negro
seems to fall short to a far greater degree than in the ele-
mentary traits which man has in common with the lower ani-
mals. In sense capacity, in instinct, in motor ability, there is
no evidence that he inferior to the white man. It is in such
matters as reasoning ability, the power to perceive relations,
to exercise creative imagination, to subordinate a present pas-
sion to a distant end, that the weight of evidence and opinion
indicates his relative deficiency.
With regard to the comparative equality of white and
negro children up to the age of adolescence and the then en-
suing superiority of the whites, the evidence is not at all clear.
The theories as to the significance of adolescence upon which
this view is based, have themselves undergone restricting
modification in very recent years, and the whole matter is at
present unsettled. There may be greater differences between
26 THE PSYCHOLOGY OF THE NEGRO.
white and negro children either before or after adolescence, so
far as is known. Or adolescence may have no appreciable
bearing upon ascertainable racial differences.
The question of differences in brain structure between the
two races is likewise subject to controversy. It seems to be
indubitable that in brain size there is a difference, but the in-
ternal structure of the brain, which is far more significant for
intelligence than size, is as yet a subject for debate rather
than for evidence in so far as it concerns differences between
whites and negroes.
The abstracts given are believed to include all of the
experimental studies and a fair sampling of the better studies
which are not experimental. It is probably true that there are
more people who believe in racial mental equality than the
reviews would indicate; equality is taken for granted, as in
the greater part of our school system and in our political life ;
it is those who believe in racial inequality who consider their
views novel enough for publication. It may be said that
the main conclusion one may draw from a study of the litera-
ture bearing upon the mental side of our race question is that
we have taken a step toward its solution, but that the problem
is still a problem.
The evidence with regard to the relative ability of pure
negroes and mulattoes will be discussed in Chapter IV, as will
that bearing upon racial variability.
CHAPTER II
THE SUBJECTS AND THE TESTS
The Subjects
The experiments to be described herein were made in De-
cember, 1914, upon pupils in the schools of Richmond, Fred-
ericksburg and Newport News, Virginia. According to the
Census for 1910 ('10), Richmond has a population of 127,628,
of whom 36 per cent, are negroes; Fredericksburg has a
population of 5874, of whom 25 per cent, are negroes; and
Newport News has a population of 20,205, of whom 36 per
cent, are negroes. In the State as a whole, 32.6 per cent, of
the population are negroes. The white inhabitants of these
cities are to a very large extent native born and of native
parentage ; in the state as a whole 95.4 per cent, of the white
population is native born and of native parentage, and in
these cities the percentage does not considerably differ from
that of the state.
The Census shows that in Richmond 1.2 per cent, of the
native white population ten years of age and over are illiterate,
while 19.6 per cent, of the negroes are illiterate. In Fred-
ericksburg the corresponding percentage of white illiteracy
is 1.5; that of negroes is 20. In Newport News the per-
centages are : whites, .6 ; negroes, 12. In the state as a whole,
8 per cent, of the white population and 30 per cent, of the col-
ored population are illiterate. It is thus evident that the
cities have a smaller percentage of illiteracy, both white and
colored, than the state, and that a much greater proportion of
the negroes than of the whites is illiterate.
The percentages of the population 6-14 years of age that
attend school are as follows, according to the Census: Rich-
mond — native whites, 79.2 per cent.; negroes, 65.2 per cent.
Fredericksburg — whites, 76 per cent.; negroes, 64 per cent.
Newport News — whites, 76; negroes, 69 per cent. In the
27
28 THE PSYCHOLOGY OF THE NEGRO.
state as a whole 73.2 per cent, of the white and 58.7 per cent,
of the colored population 6-14 years of age attend school. It
thus appears that a somewhat larger percentage of whites
than of negroes attend school, and that this difference between
white and colored school attendance is only slightly less in the
cities than in the state at large. It should be noted that there
is no compulsory education law in any of the cities mentioned,
and that only an inconsiderable fraction of the population of
the state attend school under such a law.
So far as these figures show, the white and colored popu-
lations of the cities in which the tests were made do not differ
significantly from the general white and colored populations
of Virginia. The negroes, in the cities and in the state at
large, attend school less than do the whites in proportion to
their numbers and are considerably more illiterate.
This last consideration, that the whites attend school in
larger proportion than the negroes, and that the negroes are
more illiterate, indicates that on the whole the negroes who
do attend school are a more closely selected group than are
the whites who attend school. It is a rarer occurrence for
a negro to become educated. The school selects for its opera-
tions a more circumscribed group of negro than of white chil-
dren. The Richmond School Report for 1912-'13 ('14)
strengthens this conclusion.
The figures in the report show that of the total white school
enrollment, 10.53 per cent, are in the high school ; of the total
colored school enrollment, 4.97 per cent, are in the high school.
That is, that out of an equal number of pupils from each race,
there are twice as many white as colored of high school grade.
If we compare the percentage of the total school population,
white and colored, enrolled in elementary and in high schools,
we arrive at the same result. Of the white and colored school
populations, there are 54 and 55 per cent., respectively, en-
roiled in the elementary schools; but there are 7.5 per cent,
of the white and only 3.1 per cent, of the colored school popula-
tion enrolled in the high schools. The same percentage of the
white and of the colored school populations is enrolled in ele-
mentary schools, but there is twice as great a percentage of
the white as of the colored enrolled in high schools. Of the
colored population as a whole, a smaller proportion is in school
as compared with the whites ; and of those in school, a smaller
THE SUBJECTS AND THE TESTS. 29
proportion is in high school. It is a rarer thing for a colored
than for a white child to attend school at all; it is a much
rarer thing for a colored school child to be in high school.
Colored high school pupils are the "chosen few" of their race
to a greater extent than are white high school pupils.
The nature of the selective factors which thus act more
intensively upon negroes than upon whites as the school grades
advance is difficult to ascertain. Among the causes of elimina-
tion from school are such matters as poor health, poverty,
mental or moral deficiency, lack of ambition or energy. It
would seem that these forces, in the long run, must select for
survival in the school system those who by reason of their
own capacity, as represented in themselves and in the inherit-
able traits which prompt and enable their parents to send them
to school, are best fitted to make progress in academic work.
It would seem that the school must select as well as train
those who have greatest ability and who thus profit most by
school attendance. That this is true in the case of the high
school's selection of negro pupils is especially indicated by the
following considerations.
The figures for retardation in the schools of Richmond
are as follows: In the white elementary schools, 51.8 per
cent, of the pupils are above the normal age for their grade;
in the colored elementary schools, 75.0 per cent, of the pupils
are above the normal age for their grade. While in the white
high school 52.1 per cent, of the pupils are above the normal
age for their grade, and in the colored high school, 55.8 per
cent, of the pupils are above normal age. The colored elemen-
tary pupils are 23.2 per cent, more retarded than are the white
elementary pupils; the colored high school pupils are only
3.7 per cent, more retarded than are the white pupils of their
grade. It is evident that the pupils who do not accomplish
what is expected of their age drop out of the negro schools
before high school is reached to a greater extent than out
of the white schools. Indeed, while it appears from the figures
that the colored pupils who are eliminated from the school sys-
tem are those who do not perform the work of their age, it does
not appear that this is true of the whites. It would almost
seem that whereas the negro goes to high school by reason
of his ability and determination, the white goes on account
of some other incentive, such as, perhaps, social pressure
or the custom of his class. It is not unreasonable to con-
30 THE PSYCHOLOGY OF THE NEGRO.
elude on the basis of the figures for retardation that one of
the selective factors which operate to a greater extent upon
colored than upon white pupils is inabihty to do the school work
expected of their age. In this connection it should be re-
called that Phillips, in a study reviewed in Chapter I, found
the relative percentages of white and colored retardation in
the elementary schools of Philadelphia to be about the same
as those found here ; and that his investigations with the Binet
tests showed that the greater pedagogical retardation of the
colored pupils was paralleled by their greater psychological
retardation.
When we divide the elementary school into primary and
grammar grades, we find that 35 per cent, of the white ele-
mentary pupils are in the grammar grades, while only 21 per
cent, of the colored elementary pupils are in these grades.
This is in confirmation of our conclusion that the higher grades
have a larger percentage of the white than of the colored
children. But when we divide the high school into two parts,
consisting of the first and second and the third and fourth
years, respectively, we find a different situation. Twenty-
five per cent, of the white high school pupils are in the third
and fourth years combined, while 28 per cent, of the colored
high school pupils are in the third and fourth years com-
bined. Here we have a larger proportion of colored than of
white pupils in the upper years. It is interesting to note
that Mayo, in a quotation previously given, found the same
situation in the high schools of New York. The colored pupils
studied by him remained in school longer than did the white
pupils. It seems that after the high school is reached, selec-
tive factors eliminate a larger percentage of white pupils than
of colored.
This tends to corroborate the view expressed above, that
the negro who enters high school does so because of his ability
and determination, whereas the white high school pupil often
enters by reason of social pressure, custom, or the tradition of
his race. There is a marked difference between the work of
the high school and that of the elementary school. One of
the problems of modern education is to lessen the gap between
the two. Within either school the work of a given grade is
not much more difficult than the work of the grade below it.
But the first year of the high school is much more difficult than
the last year of the elementary school. This increased diffi-
THE SUBJECTS AND THE TESTS. 31
culty causes a large number of the less capable pupils to drop
out of high school at the end of the first or second year. A
larger proportion of white than of colored pupils so drop out
because a greater proportion of white than of colored entered
without serious purpose or the requisite ability. The negroes
who enter high school are a more closely selected group, and
they therefore more nearly finish the course. The figures
show that the percentage of retardation in the colored high
school is the same for the first two years and for the last two
years ; in the white high school there is a considerably greater
percentage of retardation in the first two years than in the
last two.
Another fact which bears upon the relative action of selec-
tive factors upon white and colored children in the public
schools is that a much larger proportion of white than of
colored pupils of high school grade are not enrolled in the pub-
lic schools at all, but attend private institutions. This is par-
ticularly true in Richmond; and on the whole the pupils who
attend private schools are of better social standing, and
therefore, on the whole, probably of greater ability, than the
average of the school population. The public high school thus
loses a number of pupils of ability, and this loss is not felt by
the colored high school as it is by the white.
Taken all together, the facts brought out show that the
colored child in the schools of Richmond, in the upper grades
and especially in the high school, is much more closely selected
by reason of his ability than is the white child. We should
therefore expect the colored pupils of advanced grade to attain
a higher score in psychological tests than those of lower grade,
when compared with white pupils. This we shall find to be
true. And we shall also find, in marked confirmation of the
present contention, that colored high school pupils excel col-
ored elementary pupils to a much greater extent than white
high school pupils excel those of lower grades. Phillips, Strong
and Pyle, (see Chapter I), found the mental difference be-
tween whites and negroes to become less as the grades ad-
vance. The explanation of their findings is probably to be
found in this matter of selection. It seems likely that if one
could test a random and not an educational selection of whites
and negroes, he would not find the difference between the
races to decrease with age. And it appears to be certain that
racial mental differences discovered by means of tests upon
32 THE PSYCHOLOGY OF THE NEGRO.
school children are in reality smaller than the actual differ-
ences between the races.
The detailed figures for the school systems of Fredericks-
burg and Newport News are not available, but there is no
reason for believing they would point to a different conclu-
sion from that found in Richmond. The Richmond figures
are much more reliable than those of the other two cities
would be since they are based upon a far greater number of
pupils. It may be said that the Richmond figures are derived
from the records of 12,018 white and 6184 colored children.
The number of pupils tested in these experiments was as
follows: In Richmond, 269 white and 319 colored; in Fred-
ericksburg, 84 white and 63 colored; in Newport News, 133
white and 39 colored. In all, there were 486 white and 421
colored pupils — a total of 907. The Richmond pupils were
in the three years* of the grammar school and the four years
of the high school; in the grammar grades there were 149
white and 175 colored ; in the high school there were 120 white
and 144 colored. The Fredericksburg pupils were: white, 36
in the 6A and 7A grades and 48 in the high school; colored,
28 in the 6A and 7A grades and 35 in the high school. In
Newport News all of the pupils tested were in the grammar
grades: 133 white, in grades 6B, 7A and 7B; and 39 colored
in grades 6A and 7A. Throughout the study main reliance
will be placed upon the results obtained from Richmond, on
account of the greater number of pupils tested there ; the re-
sults from Fredericksburg and Nevv^port News will be used as
corroborative. It may be remarked that in all ways the only
difference between the results from the three cities is
that those obtained from Fredericksburg and Newport News
emphasize the racial differences found to a somewhat greater
degree than do those from Richmond.
The high schools tested in Richmond were the John Mar-
shall, white, and the Armstrong, colored. These are the only
high schools in Richmond. In the John Marshall High School
*The elementary school in Virginia covers only seven years. The first
four years are the primary, the last three are the grammar. The gram-
mar grades are 5A, 5B, 6A, 6B, 7A, 7B. In the high school there are
four years, and the grades are lA, IB, 2A, 2B, 3A, 3B, 4A, 4B. "A"
means the first half of a year; "B" means the second half of a year.
THE SUBJECTS AND THE TESTS, 33
there are* 1394 pupils, 535 boys and 859 girls; in the Arm-
strong High School there are 76 boys and 257 girls, a total of
333. The elementary schools tested were the Madison, white,
and the George Mason, colored. These were chosen because
in the opinion of the school authorities their pupils were fairly
typical of the average white and colored populations of the
city. The Madison School has 871 pupils, 398 boys and 473
girls; the George Mason School has 849 pupils, 360 boys and
489 girls. All four schools are parts of the public school
system.
In Fredericksburg, the white pupils tested were in attend-
ance upon the one public school building for whites in the
city. The colored elementary pupils were in the colored public
school. But the colored high school pupils were in a private
school conducted by colored people, since the city does not
maintain a colored high school. This private school conforms,
closely in all essential respects to the requirements for pubUc
high schools, and its pupils may be fairly compared with those
in the public schools.
In Newport News, the white pupils were in the John W.
Daniel School and the colored pupils were in the John Mar-
shall School. These schools were typical of the schools for
the two races, in the opinion of the school authorities. No
high school pupils were tested in Newport News, since there
is no colored high school.
In selecting the pupils from the various schools for the
tests, in some instances the only grade of a given degree of
advancement in the school was tested; in other instances,
where choice had to be made among several grades of a given
degree of advancement, the school authorities selected a grade
of average ability ; in still other instances, where it was neces-
sary to test only part of a given grade, the selection of pupils
was made by taking them in alphabetical order from the roll.
By these means it is believed that the selection of pupils for
the tests was made a fair one in all of the schools.
That the schools themselves were comparable as between
the two races there is no valid reason to doubt. All of them
pursued the same general course of study ; within a given city
all were parts of the same system, with the exception of the
colored high school in Fredericksburg. The teachers and

available, but they do not differ significantly from those given.
34
THE PSYCHOLOGY OF THE NEGRO.
principals of the colored schools were colored in Fredericks-
burg and Newport News. In Richmond, the colored elemen-
tary school had colored teachers and a white supervising
principal ; the colored high school had white teachers through-
out. No difference could be perceived in the attitude of the
two races toward the tests: both white and colored seemed
to enjoy the work rather than the reverse, and both worked
with vigor.
The number of pupils tested is set forth in detail in Tables
1 and 2. In the treatment of results, no account is taken
of a record from only one pupil, and the two lowest and the
two highest ages are disregarded on account of the small
number of pupils in them.

THE SUBJECTS AND THE TESTS. 35
A fact should be noted in comparing the results from the
white and the colored high schools of Richmond. The white
pupils in each of the four years tested were in the first, or
"A", half of the year's work. The colored pupils, however,
on account of the way they are classified in the school, were
in both the first and the second, the "A" and the "B", halves
of each of the four years work. To state it in another way,
the white high school pupils were in grades lA, 2A, 3A and
4A; while the colored high school pupils with whom they are
compared were in grades lA and IB, 2A and 2B, 3A and 3B,
and 4 A and 4B. Thus the colored pupils were farther ad-
vanced academically than were the white pupils in each of
the four years. For the sake of simplicity the high school
grades for both white and colored are put down as "A" grades
in the tables. But this is somewhat unfair to the white
pupils, since the colored were in both "A" and "B" grades
in about equal numbers.
The ages of the grades tested are shown in Table 3, and
the difference in ages between the two races is shown in
Table 4. The colored pupils are older, grade for grade. In
Richmond, the difference is .36 of a year, in Fredericksburg
it is 1.02 years, and in Newport News it is 1.7 years. The
difference as shown for Richmond should be reduced somewhat
on account of the fact that the colored high school pupils are
in reality more advanced in grade than the tables would indi-
cate, as was pointed out in the preceding paragraph. Stetson,

Mayo, Phillips and Pyle, (see Chapter I), also found that the
colored children tested by them were appreciably older than
white children of the same school grade, and this is indicated
by school censuses in general, (see Mayo, '13).
This age difference is significant as showing that colored
pupils are less advanced than white pupils in school work.
But it is not important in a comparison of the standing of
the two races in mental tests, if the comparison is made by
both age and grade. When the scores are compared by ages,
the white pupils in the comparison will be of higher school
grade; when they are compared by grades, the colored pupils
will be of greater age. In the former case any possible ad-
vantage will be on the side of the whites; in the latter case
it will be on the side of the colored pupils. If success in the
tests is not dependent upon school training, it is obvious
that an age comparison is the better. But if success in the
tests does depend upon school training, a comparison by grades
is to be preferred. Where the influence of school training
upon standing in the tests is unknown, a comparison by both
age and grade would seem to be advisable. In this mono-
graph the results in all of the tests are set forth by both ages
and grades, but evidence will be brought forth to show that
ability to perform the tests is not appreciably dependent upon
school training, and consequently the age comparisons are the
more reliable. A comparison by ages, indeed, is to be pre-
ferred to one by grades in all serious investigations of racial
mental differences. For a grade is essentially a group of
people selected because they are much alike in capacity. And
a mental test which is dependent upon academic training

must be comparatively worthless as an index of true racial
ability.
The Tests
The tests employed in this investigation were selected pri-
marily with a view to ascertaining racial differences in the
higher rather than in the lower intellectual capacities. It
is in the higher capacities that men are supposed to differ
most. And it is these capacities that are of greatest influence
in determining their relative achievement. The investiga-
tions previously made and the views previously held indicate
that there are no considerable group differences in sensation,
in motor control, in native retentiveness. The differences to
which evidence has pointed have been, on the side of intellect
as opposed to feeling, in such abilities as those included under
the terms constructive imagination, the apprehension of mean-
ing, reasoning power. These latter traits divide mankind
into the able and the mediocre, the brilliant and the dull, and
they determine the progress of civilization more directly than
do the simple and fundamental powers which man has in com-
mon with the lower animals. While testing these traits, it was
thought advisable at the same time to employ certain tests
of lower capacity for the sake of comparison.
The tests used were the Woodworth and Wells Mixed
Relations, I and II; a form of the Ebbinghaus Completion
Test; a Cancellation Test; and one of the Columbia Maze
Tests. A test of immediate memory was also given, but the
results from it were discarded. In this test the series of
digits to be remembered were presented orally by the ex-
perimenter, and some of the pupils, both white and colored,
undoubtedly wrote down the numbers surreptitiously as they
were called, instead of waiting until after the series were
finished. It is interesting to note that evidence of this occurs
more frequently in the results from the lower than from the
higher grades, and more frequently in the colored than in the
white schools. A possible "study of dishonesty" is suggested.
The mixed relations test, in its various forms, has been
used by a number of investigators, and has been highly recom-
mended as a test of intelligence. Wyatt ('14), in a study
undertaken in order to determine reliable intelligence tests,
found correlations of .80 and .62 between the mixed relations
test and careful subjective estimates of intelligence, in two
38 THE PSYCHOLOGY OF THE NEGRO.
groups of subjects. He also found a correlation of .85 be-
tween the mixed relations and completion tests, and states
that these two tests correlate more highly with inteUigence
than do any of the thirteen other tests employed by him,
and that they also correlate more highly with the other tests
as a whole. Vickers and Wyatt ('13) attempted to deter-
mine suitable tests for assigning children to school grades,
and found the mixed relations, completion and hard opposites
to be most satisfactory. The correlations between the mixed
relations test and intelligence, (inteUigence being defined as
adaptability to new conditions), were .51, .61, .64 and .86
with four different classes of children. The reliability of the
test, as m.easured by its correlation in repeated trials, was
high, the average correlation between the trials being .70.
Burt ('11) found a correlation of .52 with intelligence, and a
coefficient of rehability of .92. He recommends the test,
along with the completion test, as being an excellent indica-
tion of ability in logical inference or reasoning.
The particular form of the test as used is the one de-
signed and standardized by Woodworth and Wells ('11), its
originators. It consists of two parts, numbered I and H, and
is in reality two separate tests. The parts are of equal dif-
ficulty and the twenty relations in each part differ as little
in difficulty as it was possible to make them. The test is
printed in full in the appendix, as are the others used in this
investigation.
It is always difficult to state just what mental function is
experimented upon by a given test. The various traits so
overlap and are so dependent upon one another in their action
that no one trait can be completely isolated. If a test cor-
relates well with other tests of the same or related perform-
ances, it may be taken as a reliable index of ability in the
functions involved, although the specific functions themselves
cannot be definitely and exhaustively described. Most tests
are so regarded. But within limits it is possible to state
approximately the functions that are tested. The mixed
relations test is primarily one of controlled association of the
sort that is the basis of all efficient reasoning. It demands
that a relation be perceived and applied; and then that an-
other and a different relation be perceived and applied, and so
on through the test. A simple test of controlled association,
such as the opposites test, requires that a mental set or
THE SUBJECTS AND THE TESTS. 39
determining tendency be previously formed at the instance of
the experimenter, and then apphed unchanged to stimuli as
they occur. The mixed relations test goes further than this,
and requires that the mental set itself be determined by the
subject before it is applied, and that a different mental set
be fixed for each stimulus. It involves what James ('92) has
called "sagacity", and requires association by similarity, the
perception of meaning, voluntary control of ideas. Wood-
worth and Wells state that the test measures skill in hand-
ling associates by means of a determining tendency; mental
alertness and flexibility; that it is a "logical relations" test.
It is safe to say that the functions involved are those most
intimately concerned in that successful handling of material
which distinguishes the intelligent and mentally active indi-
vidual from the unintelligent and dull. The language factor
is of course present, but where the words used are simple
and well known, this is not important in a test of individual
or group differences. (See Simpson, '12, p. 69ff.).
The completion test was invented by Ebbinghaus ('97),
and has been widely used. Wyatt ('14), as mentioned above,
recommends the test as one of intelligence; he finds correla-
tions of .85 and .61 with subjectively estimated intelligence
in two classes of school pupils. Vickers and Wyatt ('13)
found correlations of .82, .88, .76 and .82 with intelligence in
four groups of subjects. And they found correlations of re-
liability of .84, .87, .66 and .69 in successive trials with the
four groups. Burt ('11), using two forms of the test, found
correlations with intelligence of .48 and .53. Brown ('11)
states that the test correlated .43 and .69 with general intel-
ligence in two groups of subjects. Simpson ('12) found a
correlation of .92 for reliability. Correlations between the
completion and a number of other tests used by him were:
hard opposites, .92; easy opposites, .75; memory of words,
.92; memory of passages, .91; cancellation, .68; adding, .71;
geometrical forms, .54; learning pairs, .72; completing words,
.50; drawing lengths, .26; estimating lengths, .52. A cor-
relation of .67 between the completion test and the average
of nine other varieites of association tests was reported by
Whitley ('11).
The form of completion test herein used is composed of the
twenty-five separate sentences which constitute sentences 23
to 47, inclusive, of a completion test designed by Mr. M. R.
40 THE PSYCHOLOGY OF THE NEGRO.
Trabue*, of Columbia University. These sentences are grad-
uated in difficulty, and have been standardized by Trabue in
experiments upon several thousand school children. Numbers
23 to 47 were selected because they were well adapted in diffi-
culty for use with the school grades to be tested. A comple-
tion test in the form of separate sentences has several advan-
tages over one in paragraph form, such as has generally been
used. Where a paragraph is employed, accidental factors are
much more likely to influence the result. The subject of the
paragraph may be relatively unfamiliar to any given pupil;
or one unusually difficult part of the whole may render the
completion of a large section of the rest unduly difficult. This
cannot occur where there are a number of separate sentences
dealing with different subjects and each counting as a unit.
Then, too, in scoring it is probably better to score on the basis
of sentences than of words. Thought proceeds by judgments,
whole sentences, not by words. And in a test of thought
power rather than of language power one should be able to
gauge the apprehension of meaning as a whole rather than
what is perhaps the more distinctively literary ability re-
quired to fit a word into a specific context. It is thought, not
its vehicle, that it is to be measured. The ability to use language
must probably remain a factor in this test, though not the
most important factor where the material is familiar. Thought
and language are largely implications of each other, and in
great measure ability in one means ability in the other. But
as far as possible the language factor should be elminated
and the thought factor emphasized.
The mental functions measured by the completion test are
akin to those involved in the mixed relations test. "This is in-
dicated by the high correlation between the two. Ebbing-
haus ('97) described it as essentially a test of intelligence,
requiring the ability to combine separate impressions into a
coherent whole. Simpson ('12) calls it a test of selective
thinking. Whitley ('11) classes it among her association
experiments. It would seem that the ability to perceive rela-
tions, to apprehend meaning, to control association in order to
fill a gap, is implied in a successful performance of the test.
Association or selective thinking or intelligence are perhaps
equally good terms to apply to the processes. In the language

of this test has been published.
THE SUBJECTS AND THE TESTS. 41
of popular speech, the test requires "good sense" and a
"quick mind".
The maze test employed is the so-called straight maze de-
signed and used at Columbia University. This has been
found (see Whitley, '11) to be the most satisfactory form of
maze test. It is comparatively easy to score, and the eye
strain resulting from its use is negligible as compared with
certain other forms of maze. A correlation of .49 was found
by Whitley between the straight and the average of three
other varieties of the test. Simpson ('12), using a scroll maze,
found a coefficient of reliability of .76 for the test and a co-
efficient of correlation of .26 with the average of twelve tests
of intellectual functions.
The traits measured are quickness and accuracy of move-
ment in drawing a line between the two sides of the maze
without touching them — motor as opposed to intellectual
abilities.
The concellation test is the familiar "A Test", designed
by Cattell and Farrand ('96). It is a regulated pied text,
and contains one hundred A's and sixteen of each of the other
letters — five hundred capital letters in all. The test has been
used by many investigators and in a variety of forms, such as
the "A— T" test, the "E— R" test, etc.; and it has been
described as a test of various functions. Pillsbury ('08) says
it is one of the best tests of degree of attention. Whipple
('10) agrees that this is one of its main features. Bourdon
('95) used it to measure discriminative ability. Judd ('07)
similarly classes it as a test of discriminative reaction. Cattell
and Farrand ('96) regarded it as a test of rate of perception.
Thorndike ('04) also used it as a test of perception. Pyle
('13) gives it as a test of perception and attention. On the
whole, it seems that the test measures all of these capacities
as they function together. To cancel A's it is necessary to
perceive them discrimnatively and attentively, and to react
by the simple cancelling movement. The correlations of the
test with other tests and with class standing are generally
small and sometimes negative. (See Whipple, '10).
In giving the tests, the instructions to the subjects were
by means of examples on a blackboard, supplemented by such
oral directions as were necessary. A constant order of suc-
cession was maintained among the tests. The maze was given
42 THE PSYCHOLOGY OF THE NEGRO.
first, while the pencils were sharp, then followed cancellation,
mixed relations I, mixed relations II, and completion. This
order was invariable except in Newport News, where, on ac-
count of a lack of time, the mixed relations and completion
tests were given first, to make sure that they, as the most
important, would be finished. The schools were taken as
wholes, one after another, and the lower grades were generally
tested before the higher. There was no appreciable chance
for aid in working the tests to be transmitted in conversa-
tion from grade to grade.
The time-limit method was used, and the effort was made
to allow just enough time in each test to enable to quickest
of all the subjects to finish. In Fredericksburg, where the
tests were given first, the time allowed for the mixed relations
test was 15 sec. longer than elsewhere, and the time allowed
for the completion test was 30 sec. longer. The time was
reduced in the other cities because several of the Fredericks-
burg subjects finished the work before the time limit was
reached. This extra time in Fredericksburg had apparently
no effect upon the relative standing of the white and colored
groups, but it is obvious that if the time allowed is longer than
is necessary for the quickest subjects to complete the test,
the group differences will be somewhat reduced. The brightest
of the pupils will not be able to accomplish as large an amount
of work as their ability warrants. On the v/hole, the time
limits as used were approximately the periods required
by the ablest of the subjects. With the exception mentioned,
these times were as follows, for all grades: each mixed rela-
tions test, 1 min., 45 sec. ; completion test, 8 min., 30 sec. ; maze
test, 1 min., 30 sec. ; cancellation test, 1 min., 20 sec. The sub-
jects were told that they would have barely time to finish if
they worked at their highest speed. In all of the tests the
directions were to try for as great speed as possible, while not
making any mistakes. If an unusually difficult part of the
test should be met, in the mixed relations and completion
tests, they were advised to pass it by without a too great waste
of time. A stop-watch was used, and all directions were given
by the writer, who also did all of the scoring.
In scoring the mixed relations test, each accurate relation
recorded was graded 2; each partially correct relation was
graded 1 ; each error was graded 0, as was each omission. The
THE SUBJECTS AND THE TESTS. 43
possible maximum score was thus 40 for each of the two parts
in which the test was given. The scoring was, of course,
absolutely uniform throughout, for each type of correct,
partially correct or incorrect record.
The completion test was scored in the same way. Each
correct sentence was rated 2; each partially correct sentence
was rated 1 ; and each incorrect or omitted sentence was rated
0. Since there were twenty-five sentences, the possible maxi-
mum score was 50.
The maze test measured two things, speed and accuracy.
Accuracy was scored by counting the number of touches made.
Speed was determined by the amount of the test completed
or the distance traversed. In rating this, each straight sec-
tion of the maze was counted 1. Since there are 140 straight
sections in the test, the possible maximum score for speed
was 140.
This test presents a difficulty in its scoring. The two
quantities which it measures are variables which do not main-
tain a constant ratio to each other. If only a short distance
is traversed within the time limit, the number of touches is
small as compared with the amount done. But if a great
distance is traversed, the number of touches is large as com-
pared with the space gone over. To illustrate: a distance of
60 will mean, say, 4 touches, a ratio of 1 to 15 ; but a distance
of 120 will mean, say, 20 touches, a ratio of 1 to 6. And yet
the latter record may be as good as the former. As speed
increases, accuracy normally decreases, and in a constantly
changing ratio.
In handling the maze test, a number of investigators have
chosen to deduct a certain arbitrary amount from the speed
record for each touch. Thus Whitley ('11) and Simpson
(*12), using the am.ount-limit method, add 5 sec. and 10 sec,
respectively, for each touch made. But this cannot be satis-
factory. A touch made by a subject who works at great speed
is far less significant than a touch made by a subject who
works at a much lower speed. Where the ratio of accuracy
to speed is a variable one, as in this case, no constant figure
can be deducted from the speed record for each error.
What is needed is a set of ratios, expressing the relation
of touches to distance at each of a large number of possible
distances. Such a set of ratios could be ascertained by ade-
quate experiment, and they would be very interesting in
44 THE PSYCHOLOGY OF THE NEGRO.
themselves and also very useful, since there is no other prac-
ticable group test of motor capacity. But at present they do
not exist, and it is therefore impossible to give the best treat-
ment to the results of the maze test.
The method that is followed herein is to set forth the num-
ber of touches and the distance covered by each group of sub-
jects. The comparison of group with group must then be
based on the relative number of touches made and the relative
distance traversed. If the score for either touches or distance,
or both, should be the same for each group, an accurate com-
parison would of course be possible. Or if one group should
exceed the other in touches but not in distance, or in distance
but not in touches, an accurate comparison could be made. It
generally happens, however, that one group exceeds the other
in both touches and distance, and in this case the difficulty
arises. The ratio of touches to distance is normally smaller
in a slow group than in a fast one, and smaller to an unknown
degree.
The cancellation test also measures both speed and ac-
curacy, but here the difficulty in equating the two is not so
pronounced. The score for speed is obtained by counting
the number of A's cancelled ; the score for accuracy is arrived
at by counting the number of A's omitted in the amount of
text gone over.
The number of A's omitted is very small, and is constantly
so from group to group. Roughly, only about one-third or one-
half of the subjects make any omissions at all. And it does
not appear that there is any very definite relation between the
number of omissions and the number of cancellations. Sev-
eral investigators have reported this to be true of the test.
Woodworth and Wells ('11) say there are no workable indi-
vidual differences in accuracy and that there is little reason
for its being scored. Binet ('03) found that subjects worked
with approximately equal accuracy. Others, as Thorndike
('04), ignore omissions in giving results from the test.
Whipple ('10) and others, however, think omissions may be
important. Both omissions and cancellations are given for all
of the groups in this study ; but it will be apparent that signifi-
cance can be attached only to the latter.
Of the tests used, the mixed relations and the completion
were given to all subjects. The maze and the cancellation
THE SUBJECTS AND THE TESTS. 45
were not employed with the white high school pupils of Rich-
mond, on account of a lack of available time. The maze was
also not used with the white elementary pupils of Newport
News. The white elementary pupils of Fredericksburg,
through an oversight on the part of the experimenter, did
not sign their names to the maze test, and their records in
this test can consequently be used only in grade and not in
age and sex comparisons.
The total time consumed by these tests in the case of any
individual subject was small, and it cannot be supposed that
the records obtained from a given individual are an accurate
index of his relative ability in the traits measured. Further
trials would be necessary to establish the final standing of
any one of the pupils in the tests. But while this is true,
it is also true that the tests are sufficient to establish with
accuracy the relative standing of large groups of subjects as
wholes, and it is a group — a racial — comparison that is in
question. Where a group is tested, the chance inaccuracies
which deflect the true position of one individual in one direc-
tion serve also to change the position of another individual in
the opposite direction, so that on the whole the central ten-
dency of the group remains unchanged from what it would
be in the case of a very great number of measurements, the
practice effect, of course, being disregarded. The individual
inaccuracies balance each other, and the group standing is un-
affected by them. It is improbable that many repeated trials
would appreciably disturb the average score. This view is
taken for granted in all tests upon large numbers of subjects ;
Thorndike ('04) gives illustrations of its validity. The mixed
relations test as herein used is another illustration, as will
appear. For the test is given in two parts — is, in reality, two
tests — and the relative standing of the groups compared is
the same in each. Woodworth and Wells ('11), indeed, recom-
mend a short test of this and related kinds as being better than
a long one, since it is freer from interferences of a disturb-
ing character. So the final average results of these tests may
confidently be taken as reliable measures of the relative ability
of whites and negroes in the traits involved, although the time
consumed in the actual testing was short.
CHAPTER III
GENERAL COMPARISON OF WHITES AND NEGROES
In the present chapter a general comparison is made be-
tween the scores of the white and the colored subjects. In set-
ting forth the results, the tables and graphs are arranged in
the same order for each test. First are given the average scores
made by each age and sex and by each grade, with their aver-
age deviations. The tables containing these data are the basis
of the comparisons made in the other tables, and they also give
the figures which are represented by the graphs. The graphs
are next in order, and serve to make the group relationships
contained in the tables somewhat plainer. It may be noticed
that the graphs and the tables of comparison which follow
them omit those ages and grades in which there are not fig-
ures for both races : no comparison is made unless the ages and
grades are alike. The results from Richmond, Fredericks-
burg and Newport News appear in succession in each table.
There are no graphs for the two latter cities.
Following the graphs, for each test come the tables in
which the group comparisons are made. First appear the
actual differences between the scores obtained by the two
races, classified by age and sex and by grades. The averages
of the separate age and grade differences are given, with their
probable errors. These averages, of course, are the most reli-
able figures for comparison. Next are the tables which set
forth the percentage of the score of the whites which was
obtained by the negroes, with the averages of the separate
ages and grades and the probable errors of the averages. The
tables which show the actual differences between the scores
and those which show the percentages deal with the same
racial differences, and are simply two ways of exhibiting the
same group relationships. Lastly, as still another mode of
comparison, for each test is given the percentage of each age
and grade of the colored subjects that reaches or exceeds the
46
COMPARISON OF WHITES AND NEGROES. 47
average score of the white subjects of the same age or grade.
The averages and probable errors of the separate age and
grade percentages are given as before. This comparison is
made only for Richmond, since the relatively small number of
pupils tested in Fredericksburg and Newport News would ren-
der it somewhat unreliable for those cities. A group com-
parison by means of the percentage of one group reaching or
exceeding the average of the other requires a rather large
number of subjects to be of value. If the number is small,
chance inequalities in the distribution of the groups may
make the percentage appear to be much too high or much too
low.
It should be said that this comparison in terms of the per-
centage of the negroes reaching or exceeding the average of
the whites is valid only in so far as the groups follow a normal
mode of distribution. That is, the average of the groups must
also be approximately the median of the groups. Or to put
it in another way, approximately fifty per cent, of the groups
must reach or exceed their own average. Otherwise, we
would have fifty per cent, of the negroes reaching or exceeding
the score obtained by 30 per cent, or 70 per cent., or any
indefinite per cent., of the whites. The ideal procedure would
be to ascertain the percentage of the negroes reaching or ex-
ceeding the median, rather than the average, of the whites.
But in the present comparison the averages and the medians
of the groups compared are approximately the same, as the
following figures will show, and the mode of comparison
adopted is a valid one.
In the mixed relations test, the percentage of the whites
reaching or exceeding their own average in Test I is 50.0,
P.E. 1.7, for all ages of the boys ; 53.5, P.E. 2.2, for all ages
of the girls; and 54.8, P.E. 1.6, for all grades. (The grades
contain both boys and girls). In Test II the percentage for
boys, all ages, is 55.0, P.E. 2.3; for girls, all ages, it is 55.9,
P.E. 2.2; and for all grades it is 55.6, P.E. 2.1. It is thus
evident that for the white subjects in this test the average
and the median are approximately the same, and that the
groups follow a sufficiently normal form of distribution for
the percentage comparison to be made in terms of the average
rather than of the median. The figures showing the percen-
tage of the colored subjects reaching or exceeding their own
average are as follows : Test I — boys of all ages, 48.4, P.E. 2.4 ;
48 THE PSYCHOLOGY OF THE NEGRO.
girls of all ages, 48.7, P.E. 2.3; all grades, 48.5, P.E. 1.4. Test
II_boys of all ages, 52.1, P.E. 2.5 ; girls of all ages, 51.2, P.E.
3.3 ; all grades, 52.0, P.E. 1.9. Thus the colored subjects are
also seen to be so distributed that their central tendency is
approximately the same whether measured by average or by
median. It worthy of note that the percentage of subjects
reaching or exceeding their own average is somewhat higher
in Test II than in Test I. This is due to the fact that the
scores themselves in Test II are higher than in Test I, on
account of the practice effect of Test I, to such extent that
several of the brighter subjects finished the second test be-
fore the time limit was reached, and thus did not attain their
possible maximum score. This lowers the average standing
in Test II so that more than fifty per cent, of the subjects
reach or exceed it. This occurs for both races, though slightly
more so for the whites than for the negroes, since the score
of the whites was greater, as will appear, and more of them
finished the test before the expiration of the time limit. A
slightly larger percentage of the negroes, as will also appear,
reached the average of the whites in Test II than in Test I.
But this should not be taken to indicate that the negroes
profited more by the practice in the first test than did the
whites: both races reached or exceeded their average in
greater numbers in the second test.
In the completion test, the percentages of white subjects
reaching or exceeding their own average are: boys, all ages,
50.2, P.E. 2.0; girls, all ages, 52.2, P.E. 1.3; all grades, 52.7,
P.E. 1.2. The percentages of colored subjects reaching their
own average are: boys, all ages, 52.6, P.E. 2.6; girls, all ages,
54.2, P.E. 2.1 ; all grades, 54.4, P.E. 1.3. In this test, as in
the mixed relations, the average and the median are approxi-
mately the same.
The maze test shows the following percentages of white
subjects reaching or exceeding their own average: boys, all
ages— Touches, 50.0, P.E. 3.3, Distance, 52.0, P.E. 1.6; girls,
all ages— Touches, 52.4, P.E. 2.4, Distance, 46.8, P.E. 2.8;
all grads— Touches, 48.2, P.E. 2.7, Distance, 49.0, P.E. 2.9.
The percentages of colored subjects reaching or exceeding
their own average in the maze test are: boys, all ages —
Touches, 46.6, P.E. 1.9, Distance, 46.4, P.E. .9 ; girls, all ages-
Touches, 45.6, P.E., .9, Distance, 44.4, P.E. 1.8; all grades-
Touches, 47.8, P.E. 2.1, Distance, 51.2, P.E. 2.3.
COMPARISON OF WHITES AND NEGROES. 49
In the cancellation test, the percentage of a group reaching
its own average or the average of another group can be validly
computed only for the cancellations, not for the omissions.
Less than half of the subjects made any omissions at all,
and the distribution of the omissions is consequently very
assymmetrical. The percentages of whites reaching or exceed-
ing their own average in cancellations are as follows: boys of
all ages, 53.0, RE. 1.3; girls of all ages, 49.6, P.E. 1.9; all
grades, 49.3, P.E. 1.4. The percentages of negroes reaching
or exceeding their own average in cancellations are: boys of
all ages, 50.0, P.E. 3.6; girls of all ages, 52.2; P.E. 3.7; all
grades, 53.7, P.E. 1.5.
These figures make it evident that we can compare the
white and colored subjects in terms of the percentage of the
colored reaching or exceeding the average of the white, since
the distributions throughout are on the whole symmetrical.*
Perhaps something should also be said as to the other
tables of comparison, those which show the actual differences
between the scores of the two races and those which show the
percentage of the score of the whites that is obtained by the
negroes. It sometimes happens that investigators average
the scores of a number of different ages or grades, and make
comparisons by exhibiting the relation between such averages.
But this procedure makes it impossible to compute the proba-
ble error of the differences, and thus renders the comparisons
doubtful. If, for example, scores from ages 11 to 18 are
averaged for two races, and a certain difference between the
averages is set forth, one cannot tell from this difference
alone whether any real racial superiority has been found.
*Note may be made of the fact that in a few ages and grades no
colored subjects reached or exceeded the average of the whites, and that
the percentage in such cases was put down as zero. But such per-
centages are really less than zero. And when they are counted as zero,
as they are, in obtaining the average for all ages or grades, it is obvious
that this procedure tends to make the average percentage too high.
That is, it tends to make the racial difference appear to be less than
it really is.
Another matter that also makes the racial differences found appear to
be less than they really are, is the fact that in the tables which show the
percentage of the score of the whites obtained by the negroes, the per-
centages are always expressed in terms of the white score. Hence
whenever the negroes have a higher score than the whites, as they do
in a few instances, the percentage expressing the fact is dispropor-
tionately large. For example, if the whites score 100 and the negroes
score 75, the percentage is 75; but if the whites score 75 and the negroes
score 100, the percentage is 133. These considerations affect the final
average-s only slightly, but they should be borne in mind.
50 THE PSYCHOLOGY OF THE NEGRO.
It may be that the separate ages show a superiority first in
favor of one race and then in favor of the other, and so on.
What is needed to determine the validity of the difference is
its probable error. This will indicate how constant the dif-
ference is from age to age — whether it is a true difference or
is due to chance. Of course it will be recognized that probable
errors can be computed for the averages of a number of dif-
ferent age or grade scores. But such probable errors will be
larger than the racial variability from age to age would war-
rant, since scores normally increase with age. And they
therefore cannot be used as accurate measures of the probable
error of the racial difference.
Where, as in the tables of comparison contained herein,
the differences between the scores of the separate ages are
found, the average of these differences can be obtained and
also the probable error of the average. If the differences for
the separate ages are pronouncedly in favor of one of the two
races, the probable error will be small as compared with the
average. Even though slight, the average difference will in-
dicate a real racial superiority if its probable error is small.
But if the differences between the separate ages are chance
differences which favor first one race and then the other, no
matter if the average difference is large, it will yet be seen
to be no true index on account of its large probable error.
This principle is as applicable to those of the following tables
which exhibit the percentage of the score of the whites ob-
tained by the negroes, as it is to those which set forth the
actual differences. In the percentage tables also, the average
of the different ages is computed and its probable error is
given with it.
Mixed Relations Test
The scores obtained by the two races in this test are shown
in Tables 5 and 6, and in Figures 1-6. It may be noted that in
Test II the scores are somewhat higher than in Test I. This
is evidently due to the practice that the first test afforded.
It may also be noted, (Figs. 3 and 6), that there is a pro-
nounced jump in the scores of the colored grades when high
school is reached, and that this jump does not occur in the
scores of the white grades. This is probably the effect of the
more intense action of selection upon the colored than upon the
white high school pupils, as was pointed out in the preceding
COMPARISON OF WHITES AND NEGROES.

chapter. In some of the high school years the colored are
superior to the white subjects, but this does not occur in the
elementary school.

COMPARISON OF WHITES AND NEGROE^S. 55
It is interesting to note that the gradual increas-.e in the
scores as the age of the subjects increases comes to a stand-
still in the upper years; indeed, the graphs show thad the
older pupils as a whole have somewhat lower scores than tK^ose
immediately below them in age. This is to be expected. In a
group of pupils taken from any limited number of school
grades, those whose ages are highest will not do as well in
tests of ability as their ages would seem to warrant. When
the elementary school pupils alone are classified by age their
scores do not progressively increase, but instead tend to de-
crease in the upper years as do those of the high school pupils
represented in the graphs. The white elementary pupils tested
in Richmond ranged, in numbers large enough for compari-
son, from 11 to 15 years of age, inclusive. And their scores
for each age were as follows: Mixed Relations Test I — Boys,
14.8, 15.0, 17.3, 16.0, 13.7; Girls, 16.9, 18.8, 17.0, 17.2, 15.2.
Mixed Relations Test II— Boys, 16.5, 18.0, 20.6, 22.1, 15.0;
Girls, 22.0, 22.1, 21.0, 17.4, 16.7. The scores for the dif-
ferent ages of colored elementary pupils behaved in the
same way. It is thus evident that there is precisely the same
sort of decrease in the scores of the higher ages that was
found for the high school pupils.
The explanation of this decrease with age is probably to
be sought in the bearings of the general fact that within
any school grade the younger pupils have greater natural
ability than the older. If the older pupils had had great
ability, they would have passed out of the grade; that the
younger pupils are so advanced as to be classed with the
older pupils is evidence of their considerable capacity. The
younger pupils in a shorter length of time have done the
same amount of work that the older pupils have done in a
greater length of time. A grade contains the best of the
young and the worst of the old. So when the pupils in the
upper grades of the elementary school are classified by age,
it is apparent that the older pupils will be those of less native
ability and the younger pupils will be those of greater native
ability. The younger pupils in the upper elementary grades
are the best of their age; the older pupils are the poorest of
their age. The poor and mediocre pupils of the same age
as the younger group have not yet reached the higher grades
of the elementary school; the able pupils of the same age as
the older group have passed on into high school. The same
V
56 / THE PSYCHOLOGY OF THE NEGRO.
reasoning- applies to the school system as a whole, including
the hi'^h school as the highest grades. The older pupils in
the upper grades of the high school have not as great natural
ability as the younger pupils. The ablest pupils of the same
age as the older group have finished the high school course,
and left behind only the mediocre and the poor. But the
younger group is composed of the brightest pupils of their
age, for those of less ability have not yet reached the upper
grades. That this explanation of the smaller scores made
by the oldest pupils tested is pertinent, is further indicated
by the fact that the graphs which give the scores by grades
do not show the decrease for the advanced pupils as it is shown
by the graphs which give the scores by ages. Grades are
supposedly groups of an increasiing degree of ability.
The truth of the view set forth above is still further borne
out by an incidental comparison that came to light in the
present investigation. In the elementary schools at Richmond
were tested 30 white boys, 20 white girls, 24 colored boys and
38 colored girls, 112 in all, of ages 14 and 15, combined. In
the high schools at Richmond were tested 18 white boys, 25
white girls, 10 colored boys and 31 colored girls, 84 in all, of
ages 14 and 15, combined. It is true that there was a larger
proportion of 14 than of 15 year old pupils in the elemen-
tary groups, and a larger proportion of 15 than of 14 year old
pupils in the high school groups. But this is of no conse-
quence, since the 14 year old elementary pupils are fully as
able as those 15 years old, as was shown two paragraphs
above; and since the same thing is true of 14 and 15 year
old pupils in the high school, as will be shown three paragraphs
below. So these groups may be considered as of the same
age, one set being in the elementary school and one set in the
high school. The scores obtained by them in three tests were
as follows:
Mixed Relations Test I — White Boys, Elementary, 14.8,
High School, 24.1 ; White Girls, Elementary, 16.2, High School,
27.7 ; Colored Boys, Elementary, 10.2, High School, 22.0 ; Col-
ored Girls, Elementary, 8.9, High School, 23.9. Mixed Rela-
tions Test II — ^White Boys, Elementary, 18.5, High School,
28.6; White Girls, Elementary, 17.0, High School, 33.7; Col-
ored Boys, Elementary, 12.3, High School, 31.8 ; Colored Girls,
Elementary, 10.2, High School, 29.0. Completion Test— White
Soys, Elementary, 18.4, High School, 28.6; White Girls, Ele-
COMPARISON OF WHITES AND NEGROES. 57
mentary, 16.1, High School, 33.1; Colored Boys, Elementary,
12.6, High School, 23.5 ; Colored Girls, Elementary, 15.6, High
School, 25.4. The maze and cancellation tests did not bring
out marked differences anywhere, as will appear, and the dif-
ferences revealed by them in this comparison of the elementary
and high schools were not considerable.
These figures show that the white high school pupils ob-
tained on the whole nearly twice the score that was reached
by the elementary pupils of the same age; and that the col-
ored high school pupils obtained on the whole more than twice
the score that was received by the equally old elementary
pupils. Thus is borne out the contention that the older pupils
in the upper grades of the elementary school are the poorest
of their age; the brightest of their age have passed beyond
the elementary school. And it is reasonable to suppose that
the same state of affairs exists in the upper high school grades.
The able 18 year old students have gone out of the school and
left behind their less able fellows. And these are inferior to
pupils of normal high school ability at a lower age.
It follows as a corollary of the above, that the youngest
pupils represented in the graphs have scores which are too
high to be truly representative of their ages. The lowest ages
in any limited number of grades contain only the brightest
pupils of those ages; the mediocre and the dull have not yet
reached the grades in question. While the highest ages score
too low, the lowest ages score too high. So it appeared that
the youngest and the oldest pupils in the elementary grades
tested in Richmond stood close together in their scores, and
this was probably on account of the undue superiority of the
young as much as on account of the undue inferiority of the
old. The same is true of the high school taken alone. Ages
14 to 18, inclusive, were represented in the Richmond high
schools in sufficient numbers for comparison. The scores
received by the different ages of both white and colored pupils
behaved in the same way; the scores of the white high school
pupils follow: Mixed Relations Test I— Boys, 23.1, 25.2, 31.3,
25.6, 25.0; Girls, 30.3, 25.2, 25.6, 20.1, 16.6. Mixed Relations
Test H— Boys, 29.0, 28.3, 36.8, 34.6, 29.6; Girls, 35.4, 32.0,
32.5, 28.0, 23.0. As in the case of the elementary school, the
oldest and the youngest high school pupils do not stand far
apart in their scores. And as the older pupils scored too low,
so the younger pupils scored too high. ' This is evidenced by
58 THE PSYCHOLOGY OF THE NEGRO.
the fact that when all of the pupils of their age, both elemen-
tary and high school, are considered together, the resulting
score, which is the true one, is much lower. Of course it is
the combined score of both high school and elementary pupils
of the same age that is represented in the tables and graphs.
This suggests a matter to which attention should be called.
The attempt is sometimes made to establish norms for vari-
ous ages of pupils in psychological tests. The idea is to as-
certain by a large number of experiments the performance
that may be expected from a child of a certain age. But it is
very evident that such attempts can only serve to mislead if
they deal, say, with pupils in the higher elementary grades
without taking the high school into consideration, or if they
deal with the lower grades of the high school without taking
the elementary school into consideration. In the former case,
the resulting norms for the higher ages will be much too low ;
in the latter case, for the same ages, they will be much too
high. A fourteen or fifteen year old child in the school system
is not a typical fourteen or fifteen year old child. He is typi-
cal of a child of his age in high or in elementary school,
and not in general. The only way in which valid age norms
may be established is by testing the ages throughout their
normal distributions among the grades. Or if only one school
is tested, the elementary or the high school, it should at least
be stated that such is the case, so that one may be able to
make proper allowances for the findings reported. Even this
has not always been done.
Attention may also be called to the bearing of the compara-
tives scores of the elementary and high school pupils of the
same age upon a contention that was made in the preceding
chapter. These scores show that the high school pupils are
superior to the elementary school pupils of equal age to a
considerably greater extent in the case of the negroes than
of the whites. The high school negroes more than doubled
the score of the elementary school negroes in each of the four
comparisons in the mixed relations test, but the high school
whites did not double the score of the elem.entary whites in
any of the four comparisons ; in the completion test, the high
school doubled the score of the elementary school only in the
case of the white girls. This fits in with the other indications
that the colored high school is a more closely selected group
from the point of view of ability than is the white high school.

To return to the comparative scores of negroes and whites
in the mixed relations test. Tables 7-11 give the detailed
comparisons. In every instance, as shown by the averages,
the whites surpassed the negroes, and the probable errors are
so small as to render the averages very reliable. In Test I,
in Richmond, the colored boys obtained 72.9 per cent, of the
score of the white boys; the colored girls obtained 83.9 per
cent, of the score of the white girls; the colored grades ob-
tained 78.3 per cent, of the score of the white grades. In Test
II, the colored boys and girls obtained 78.9 and 78.1 per cent.,
respectively, of the score of the white boys and girls, and the
colored grades scored 75.7 per cent, as high as did the white
grades. The figures are very constant. We may conveniently

average the percentages for boys, girls and grades, and find
that in Test I the colored pupils obtained 78.4 per cent, of the
score of the whites, and that in Test II they obtained 77.6
per cent, of the white score. In Fredericksburg and Newport
News the percentage of the score of the whites obtained by
the negroes was considerably smaller than in Richmond.
The figures showing the percentage of Richmond negroes
reaching or exceeding the average of the whites are as follows :
Test I— Boys, 24.4; Girls, 34.5; Grades, 33.0. Test II— Boys,
35.4 ; Girls, 35.6 ; Grades, 33.9. Averaging the percentages for
boys, girls and grades, we find that in Test I 30.6 per cent,
of the negroes reached or exceeded the white score, and that
in Test II 35.0 per cent, of them reached or exceeded the score
of the whites.
It is apparent that this test reveals a considerable differ-
ence between the two races. In both the first and second
tests the difference is about equally marked, and it is approxi-
mately the same for both boys and girls and for both ages and
grades.
Completion Test
The actual scores in the Completion Test appear in Tables
12 and 13, classified by age and sex and by grades. These
tables are the basis of Figures 7-9, and of Tables 14-18, in
which the detailed comparisons are made. In this test, as in
the mixed relations, though to a less degree, may be noted
the relative superiority of the higher colored grades, and the
fact that the higher ages, on the whole, do not show pro-
gressively increasing scores as do the lower ages.

The colored boys in Richmond obtained 78.5 per cent, of
the score of the white boys. The colored girls obtained 80.0
per cent, of the score of the white girls. And the colored
grades obtained 81.7 per cent, of the score of the white grades.
The average for boys, girls and grades is 80.1. In Fredericks-
burg and Newport News the negroes are more inferior to the
whites than in Richmond, as was the case in the mixed rela-
tions test. And the difference between the races is about the
same for both boys and girls and for both ages and grades.

The racial differences are very similar in all respects to
those brought out by the mixed relations test. They are
equally constant in the two tests, the small probable errors
render them equally valid, and they are of approximately
equal amounts. This was to be expected, since the two tests
deal in general with the same mental traits, and the results
from the two serve to reinforce and establish the validity of
each other. The results from the two tests and the three
cities and in the various modes of comparison make it in-
dubitable that in the important mental capacities measured
whites are much superior to negroes.
Just how much the whites are superior in the traits meas-
ured it is impossible to say. For we do not know the zero
point of the tests. Averaging the results from the mixed
relations tests, I and II, and from the completion test, we find
that in the tests themselves the negroes did 78.7 per cent, as
well as the whites. But we cannot say more than this. We
cannot say that the negroes have 78.7 per cent, of the ability
of the whites, for we have no index of where the ability in
question begins.

THE PSYCHOLOGY OF THE NEGRO.
Maze Test
The scores for the maze test are set forth in Tables 19
and 20. These tables, so far as they concern Richmond, are
made plainer by Figures 10-12. An examination of these fig-
^lres shows that in every age for each sex, and in every grade
•except one, the whites covered a greater distance and made
more touches than did the negroes. This seems to be a racial
difference for the subjects tested. It appears in the Freder-
icksburg results as well as in those of Richmond. The negroes
were more careful than the whites. The significance of this
is difficult to tell. And it becomes especially difficult when it
is considered in connection with the fact, which will appear,
that the negroes were not more careful in the cancellation
test.

It is not apparent that there is any general increase or
decrease in either the distance covered or the number of
touches, or in the ratio between the two, as the age of the
pupils advances. The difference in ages, indeed, may fairly be
disregarded.

COMPARISON OF WHITES AND NEGROES. 71
When we attempt to decide which race was superior in this
test we encounter the difficulty in evaluating speed and ac-
curacy that was discussed in the preceding chapter. Tables
21-25 give the detailed comparisons for both speed and accu-
racy — distance and touches. The Fredericksburg compari-
sons, on the whole, are fairly sure, although the probable
errors are large. The tables show that in Fredericksburg the
colored subjects exceeded the white subjects in number of
touches made, but were inferior to them in distance covered,
and that this was true for both sexes and for the grades. The
negroes attained less speed and were at the same time more
inaccurate. Consequently they were inferior to the whites.
But in Richmond a conclusion cannot be drawn so readily.
Here the colored subjects were slower, as in Fredericksburg,
but, unlike those in Fredericksburg, they were also more accu-
rate than the whites. The colored boys covered 86.6 per cent, of
the distance covered by the white boys and made 69.6 per cent,
as many touches. The colored girls scored 79.8 per cent, of
the distance of the white girls and 60.2 per cent, as many
touches as the white girls. The scores for the grades show
that the colored pupils scored for distance and touches, re-
spectively, 85.2 per cent, and 70.0 per cent, as high as did the
white pupils. These figures are fairly uniform for the differ-
ent classifications of the subjects, and their probable errors
are sufficiently small for reliability. If we average the per-
centages given for boys, girls and grades, we find that the
negroes covered 84 per cent, as great distance as the whites
and made 67 per cent, as many errors.

The percentages of colored subjects reaching or exceeding
the average of the white sho[vv' the same relative standing for the
two races in touches and distance traversed as is evident from
the preceding figures. These percentages are as follows: Boys —
Touches, 25.0, Distance, 31.6; Girls — Touches, 19.4, Distance,
26.8; Grades — Touches, 29.3, Distance, 31.8. If we average
the percentages for boys, girls and grades, as before, we find
that 25 per cent, of the negroes reached the average of the
whites in touches, and that 30 per cent, of them reached the
average of the whites in distance.
Do these facts indicate that the colored subjects were
superior, inferior or equal to the white? A reference to the
graphs will make it evident that a large score for distance
implies a relatively higher score for touches than does a small
score for distance. The ratio of touches to distance becomes
greater as distance increases. And this change in the ratio
takes place with marked constancy throughout the graphs.
It is normal for the smaller of two scores for distance to have
a relatively smaller score for errors. The question to be set-
tled in this comparison is whether a distance 84 per cent,
as great as another distance normally implies 67 per cent,
as many touches for the former distance as for the latter.
If so, it is apparent that there is no diflference between the
ability of the white and the colored subjects in this test. And
the following considerations indicate that such is the case.
Since the score of the negroes for distance is 84 per cent,
of that of the whites, 100 may be taken to represent the actual
distance score of the whites and 84 to represent the actual
distance score of the negroes. Now a reference to the graphs
shows that colored grades 5A and 7B, and colored girls aged
14 and 15, scored approximately 100 for distance. And the
average number of touches made by these four groups of col-
ored pupils was 40, the variation being slight. A further ref-
erence to the graphs shows that colored grade 5B, colored
girls aged 11, 12 and 13, and colored boys aged 11, 13 and 15,
74 THE PSYCHOLOGY OF THE NEGRO.
scored approximately 84 for distance. And the average num-
ber of touches made by these seven groups of colored pupils
was 28, the variation again being slight. Here we have two
sets of colored pupils scoring 100 and 84, respectively, for dis-
tance, and 40 and 28 for errors. Twenty-eight is 70 per cent,
of 40, and 84 is 84 per cent, of 100. Thus we have the slower
set of colored pupils attaining 84 per cent, as great distance
as the faster set, and making 70 per cent, as many errors.
But these are approximately the figures which represent the
difference between the whites and the negroes. So it seems
that we can confidently conclude that there is no racial differ-
ence in ability revealed by the maze test. Wherever the ne-
groes work as rapidly as the whites, they make approximately
the same number of errors.
The graphs show no records of white subjects with as small
scores as 84 for distance, and we therefore cannot ascertain
the actual number of errors made by whites who worked as
slowly as the assumed average of the negroes. But there is
no reason for believing there would have been any appreciable
racial difference if slow white records had occurred. When
we compare the white groups who attained a distance of 100,
the assumed average of the whites, with the colored groups
who worked rapidly enough to attain this distance, we find the
number of errors made by the two groups to be about the
same. White grades 6A, 6B and 7A, white girls aged 14, and
white boys aged 12, 13 and 14, scored approximately 100 for
distance. And the average number of errors of these seven
groups, the variation being small, was 44. In the preceding
paragraph it was pointed out that the four colored groups
who worked at this speed scored an average of 40 errors. The
difference between the two sets of pupils, white and colored,
is thus inconsiderable.
Finally, the reader may be referred to the white and col-
ored columns in the graphs themselves. An inspection shows
that wherever the column for the whites approaches that for
the negroes in total height, representing distance, the cross-
lines on the two columns, representing errors, correspondingly
approach equality. And within the colored columns them-
selves, as within the white columns, greater total height means
not only an absolutely but a relatively greater height for the
cross-lines.
On the whole, while the whites were superior to the negroes

75
in Fredericksburg in the motor ability tested, they were not
superior in Richmond. Greater weight shguld be attached to
the Richmond results on account of the larger number of sub-
jects tested there.

*The total height of the columns indicates the score for cancellations;
the height of the cross-lines indicates the score for omissions.
A reference to the graphs will show that there is no con-
stant relation between the omissions and the cancellations,
and that in all cases the omissions were very few. Only a
small number of pupils, less than one-half, made any omissions
at all. This accounts for the large deviations of the scores
for omissions as shown in the tables mentioned, and for the
very erratic behavior of these scores in the tables of ccompari-
son. Tables 28-32. On the whole, the negroes seem to have made

slightly more omissions than the whites, but the size of the
probable errors indicates that this may have been a chance
occurence. Certainly the negro girls, who, as will appear,
are definitely superior to the white girls in cancellations, do
not show as great excess in omissions as do the negro boys,
and the negro boys are not superior to the white boys in can-
cellations at all. The omissions, therefore, will be disregarded

scores and thus seemed to be more careful than the whites,
does not occur in the test for cancellation.
Another matter that may be remarked is that the large
deviations of the scores for omission is in decided contrast
with the small deviations of the cancellation scores, when the
two sets of deviations are compared with the relative size of
the scores themselves. That is, the so-called coefficients of
variation are larger for omissions than for cancellations. A
similar situation appeared in the maze test. Here the devia-

tions of the scores for touches were as large as those of the
scores for distance, while the former scores were not over
one-third as large as the latter. Now both omissions and
touches are measures of accuracy and both cancellations and
distance are measures of speed; the two tests measure the
same phenomena, one in the field of movement and the other
in the field of perception and reaction. And in both tests there
is greater uniformity in speed of performance than in accuracy.

82 THE PSYCHOLOGY OF THE NEGRO.
In explanation of this it may be suggested that individuals
differ in their attitude toward the tests as well as in their
ability to perform them. Of course those who emphasize
speed will neglect accuracy and those who emphasize accuracy
will neglect speed. These matters will normally adjust them-
selves among a large number of subjects, and the final scores
for accuracy and speed will not be affected. But with refer-
ence to approximating the average score it may be that speed
of reaction will more readily take care of itself than will
accuracy in a normal performance of a test. At the start,
subjects are set to attempt a performance that will be in
large measure speedy, and at least a reasonable degree of
speed is put forth by all. Accuracy, however, requires more
constant care on the part of the performer ; neglect of accuracy
is not so apparent to him while he is reacting — he may not
notice the omitted letter or the touch. It is more difficult to
gauge and to control accuracy than speed. And so, unless
there is a very careful adjustment of attitude toward accuracy
by all subjects, it will vary considerably, while speed will vary
to a less degree. Consequently a greater deviation for accuracy
than for speed is to be expected in tests involving both factors.
The tables which make the comparisons between whites
and negroes in cancellation show the following facts : In Rich-
mond, the colored boys obtained 98.4 per cent, of the score of
the white boys. The colored girls obtained 112.0 per cent, of
the score of the white girls. And when classified by grades —
the grades contain a larger proportion of girls than of boys —
the colored pupils obtained 110.2 per cent, of the score of the
white pupils. This inferiority of colored to white boys may
be disregarded, since it falls within the range of the probable
error. It may be said that the boys of the two races did about
equally well. But the colored girls and the colored grades are
clearly superior to the white girls and grades, the probable
errors in these cases being sufficiently small for reliability.
In Fredericksburg, the colored boys, girls and grades are
all definitely superior to the white. In Newport News, a very
slight superiority is shown by the colored boys, but this may
be discounted as was the inferiority of the colored boys in
Richmond. The colored girls seem to be inferior here, but
this is not well established when considered in connection with
the probable error. The grade comparison is considerably
COMPARISON OF WHITES AND NEGROES. 83
in favor of the colored pupils, but it is based upon figures
from only one grade of each race.
The percentages of colored subjects reaching or exceeding
the average of the white, in Richmond, are as follows: Boys,
47.8; Girls, 68.2; Grades, 67.2. As in the former comparison
for Richmond, the size of the probable errors renders it un-
safe to say there was any real difference between the boys
of the two races; but the colored girls and grades are un-
doubtedly superior.
Taken all together, the figures show that the colored girls
are superior to the white girls in the traits measured by this
test, and that the colored boys are not appreciably inferior to
the white boys. This sex difference between the races is in-
teresting, but no satisfactory explanation of it suggests itself.
It is confirmed by Pyle ('15), in the study previously men-
tioned. From the figures which he gives it may be calculated
that in the "A Test" — the cancellation test used here — the col-
ored boys tested by him obtained 98.4 per cent, of the score
of the white boys and the colored girls obtained 108.2 per cent,
of the score of the white girls. These are almost identical
with the figures found herein.
In this connection it may be said that no other constant or
reliable racial sex difference in ability is indicated by this
study. The scores of the boys of both races were generally,
though not always, slightly lower than the scores of the
girls, as is usually the case in psychological tests. And on the
whole there is a slightly smaller difference between the white
and negro girls than between the white and negro boys, but
this is not at all invariably true. Pyle states, as quoted in
Chapter I, that in the tests which he employed the girls of the
two races stood nearer together than did the boys.
CHAPTER IV
COMPARISON OF SUB-CLASSES OF NEGROES
The terms negro and colored have been used interchange-
ably in this study, (except in the tables and the graphs), and
they are generally so used. But it is obvious that such usage
is justified only by convenience and not by fact. The so-called
negroes of the United States are negroes only in part ; in large
measure they are people of mixed blood, and the intermixture
has been almost entirely with the white race. There are all
degrees of intermixture, ranging from almost pure negro
to almost pure "white. "Mulatto" is the term generally em-
ployed to describe persons of this mixed stock. But here
again the usage is justified only by convenience, since a
mulatto, strictly speaking, is the offspring of the union of a
pure white and a pure negro. The terms quadroon, meaning
the child of a mulatto and a white, and consequently three
parts white and one part negro ; and octoroon, meaning a child
of a white and a quadroon, seven parts white and one part
negro, are fairly common. But there is no recognized term to
describe the racial status of the offspring of a pure negro
and a mulatto, who is three parts negro and one part white.
"Sambo" has been suggested for this purpose, but the popular
connotation of the word is not such as to convey the desired
meaning. And there are no widely accepted terms to describe
other degrees of race admixture. The need for them has not
been felt.
The relative number of pure negroes and persons of part
negro blood in this country is not accurately known. The
Federal Census has made an attempt to determine this, and
its figures are the most reliable that we have. The negroes
were classified as black and mulatto. But as stated in the
census report ('10, p. 79) : "Considerable uncertainty neces-
sarily attaches to this classification, however, since the ac-
84
COMPARISON OF SUB-CLASSES OF NEGROES. 85
curacy of the distinction made depends largely upon the judg-
ment and care of the enumerators. Moreover, the fact that
the definition of the term 'mulatto' adopted at different cen-
suses has not been entirely uniform may affect the compara-
bility of the figures in some degree. In 1870, as in 1910,
however, the term was applied to all persons having any per-
ceptible trace of negro blood, excepting, of course, negroes of
pure blood." The census shows that in 1910, 79 per cent, of
the negro population of the country was black and 21 per cent,
mulatto— roughly speaking, there were about eight million
blacks and two million mulattoes. In Virginia, the negro pop-
ulation was 67 per cent, black and 33 per cent, mulatto. In
Richmond, the percentages of blacks and mulattoes were 60
and 40, respectively.
The percentage of mulattoes is generally higher in the
cities than in the rural districts. In Virginia, the five cities
with a population of 25,000 or over have an average of 43 per
cent, of mulattoes in their negro populations. This figure,
when compared with the mulatto population of the state, is
fairly typical of the larger proportion of mulattoes in the
cities of the country at large.
The percentage of mulattoes is also in general considerably
higher in the North than in the South. The states with the
largest negro populations have the largest percentage of pure
negroes, though there are exceptions to this relation. South
Carolina, Alabama and Georgia, for example, have negro
populations of 55.2, 42.5 and 45.1 per cent., respectively. And
the percentages of mulattoes among the negroes of these states
are 16.1, 16.7 and 17.3, respectively. In Illinois, Pennsylvania
and Massachusetts, the negroes are 1.9, 2.5 and 1.1 per cent, of
the total populations. And in these states the percentages of
mulattoes are 33.8, 19.2 and 36.7. States with negro popula-
tions intermediate between the two groups mentioned are
Kentucky, Tennessee and Maryland, which have in their re-
spective populations 11.4, 21.7 and 17.9 per cent, of negroes.
And here the percentages of mulattoes are respectively 25.2,
25.1 and 18.6. On the whole, there are larger percentages
of mulattoes among the negroes in states with small negro
populations, and there are larger percentages in the cities
than in the country districts.
What these facts indicate it is difficult to say. They may
mean that mulattoes are more attracted than are pure negroes
86 THE PSYCHOLOGY OF THE NEGRO.
by the reputed advantages held out to colored people in
the North, and by the reputed opportunities of city life. If
so, it would seem that mulattoes have greater capacity for
perceiving opportunity and greater ambition to take advantage
of it. Or color distinctions among the negroes themselves
may influence those of lighter skin to seek to relieve the cir-
cumpressure of the bulk of their race by Northern and urban
migration. Or the non-agricultural industries in which ne-
groes are engaged in the North and in the cities may possibly
select mulattoes in preference to blacks, either because of
their lighter color or because of their greater ability, or for
both reasons. Or it may be that there is greater race inter-
mixture in the North and in the cities than in the rural dis-
tricts and the South. All four of these factors may operate.
The census shows that there has been taking place a migra-
tion of negroes from the country to the city, and from the
South to the North — ^particularly to the cities of the North.
And it is in these centers of migration that the proportion of
mulattoes is highest. Several observers, (see Stone ,'08, p.
401, ff.), have reported the apparent growth of a class dis-
tinction between mulattoes and pure blacks, tending to sep-
arate them, especially in the cities. The occupations in which
negroes are employed in the cities and in the North have
increased and become more standardized in recent years, and
intelligence and light color are both probably more in demand
in such occupations than in the more simple and isolated labor
of rural life. And the life of the so-called underworld of cities,
and the fact that inter-racial marriages are permitted in the
North, would probably tend to increase the percentage of
mulattoes in these places. So while the causes of the distri-
bution of mulattoes cannot be definitely stated, it would seem
that those mentioned above may reasonably be included among
them.
It is further worthy of note, that according to the census
figures the relative number of mulattoes is increasing. The
years in which they were separately classified were 1850, 1860,
1870, 1890 and 1910. And the percentages of mulattoes in the
country at large were as follows in those years: 11.2, 13.2,
12.0, 15.2 and 20.9. But this does not mean, as is often sup-
posed, that intermixture of whites and negroes has increas-
ingly taken place in accordance with these percentages. The
relative increase in the number of persons of mixed blood
COMPARISON OF SUB-CLASSES OF NEGROES. 87
may have been due to marriage among colored people them-
themselves, after a certain degree of racial admixture had oc-
curred, without an increase, or even a continuance, of direct
crossing between negroes and whites. For the mulattoes and
the pure negroes marry each other, and this reduces the
original percentage of pure negroes among the total offspring,
and increases the percentage of persons of mixed blood. Of
course, in the long run, unless there were a new infusion from
white stock, the amount of white blood would become very
small in any individual. But within the years covered by
the census reports there would be enough traces of the white
left to cause the individuals possessing them to be classified as
having some white characteristics, and the basis of the census
classification is the possession of any perceptible trace of
white blood. This consideration renders the increase of racial
intermixture as indicated by the census figures undoubtedly
too high, even if the accuracy of the figures be granted.
Views of Other Writers
The presence of the mulatto element among the colored
population has been taken into account by a number of writers
who have dealt with the negro, although it has been neglected
by a number of others. In Chapter I was quoted a statement
from Strong ('13) to the effect that she divided the negroes
tested by her into three classes on the basis of the color of
their skin, and found that those of lightest color varied most
from the normal, both above and below. Mayo ('13) was
aware that the presence of mulattoes might have influenced
the school records of the negroes in his study. Pyle ('15)
suggested that the superior negroes in his groups might have
had a greater proportion of white blood. And Bean ('06)
recognized that the brains which he investigated were partly
those of mulattoes. Statements from other writers may be
given to indicate the attitude of those who have considered
the matter from various standpoints.
Boas, in concluding a discussion of the American negro
problem, writes : "It appears .... that the most important
practical questions relating to the negro problem have refer-
ence to the mulattoes and other mixed bloods — to their physi-
cal tjrpes, their mental and moral qualities, and their vitality.
When the bulky literature of this subject is carefully sifted,
little remains that will endure serious criticism; and I do
88 THE PSYCHOLOGY OF THE NEGRO.
not believe that I claim too much when I say that the whole
work on this subject remains to be done. The development
of modern methods of research makes it certain that by care-
ful inquiry definite answers to our problems may be found.
Is it not, then, our plain duty to inform ourselves, that, so far
as that can be done, deliberate consideration of observations
may take the place of heated discussion of beliefs in matters
that concern not only uorselves, but also the welfare of
millions of negroes?" (11, pp. 277-278).
Stanley Hall says: "The chief event in the history of the
Southern negro in the new world is the infiltration of white
blood. But for this the negro in mind and body would be so
distinct from us that all our problems connected with the race
would be vastly simplified. Just how far he has lost his rare
racial homogeneity here it is impossible to tell. The extreme
minimal estimate that I have found is that one-tenth have
some white blood, and one maximal estimate is that two-
thirds are partly white. Page thinks that from one-ninth
to one-sixth are mixed. DuBois says that two million negroes
have some white blood. Most estimates range somewhere
between one-fifth and one-half Moreover, the grade
of pigmentation is not a sure index of the degree of miscege-
nation, and in the veins of some thought purely African prob-
ably flows at least a little of the best white blood of the land.
.... Thus all the vast psychophysic differences between the
two races are bridged, and they possibly fuse with each other
by all imperceptible gradations At any rate, men like
Fred Douglas, Bishop Payne, Booker Washington, Du Bois
Chestnut, Tanner, Dunbar, Thomas and a score of others, are
not typical negroes." ('05, pp. 360-361).
In a discussion of the general status of the mulatto as
compared with the pure negro, Jordan (*13) contends that
the former is considerably superior to the latter. The pure
negro is claimed to be capable of only the rudiments of civiliza-
tion. His powers of attention and reflection are poor. He
can draw general conclusions from particular cases only with
diflficulty, he is imitative rather than creative, he lacks fore-
sight, he has small power of profiting by observation, his
character is mobile, and he is guided largely by the instinct
of the moment. "The negro cannot undergo mental develop-
ment beyond a certain definite maximum. The curious thing
is that no attempt is made to establish this opinion on a
COMPARISON OF SUB-CLASSES OF NEGROES. 89
scientific basis and to definitely determine the limit of mental
development beyond which the law of diminishing returns
dictates cessation of effort ; and furthermore that in flat con-
tradiction to this common opinion education is planned in
apparent utter disregard of it." ('13, pp. 578-579). But with
the mulatto the case is different. "Where negro, mulatto /
and white are jointly concerned the teachers are unequivocal
in their opinion that mental alertness and the development of
the higher psychical activities corresponds in degree quite
uniformly with the amount of 'white' blood as judged by
color of the skin." ('13, p. 577). It is true, argues Jordan,
that many mulattoes are inferior, but this is because they
come from inferior parents. The way to uplift the negro
race is by the proper selection and breeding of mulattoes.
A view very different from this is held by Le Bon. He
writes: "Doubtless very different races, the black and the
white for example, may fuse, but the half-breeds that result
constitute a population very inferior to those of which it is
sprung, and utterly incapable of creating or even of continu-
ing, a civilization. The influence of contrary heredities saps
their morality and character. When half-breeds, the off-
spring of white men and negroes, have chanced to inherit a
superior civilization, as in Saint Domingo, this civilization has
speedily been overtaken by the most lamentable degenera-
tion. Cross-breeding may be a source of improvement when
it occurs between superior and sufficiently allied races, such
as the English and the Germans in America, but it always
constitutes an element of degeneration when the races, even
though superior, are too different." ('98, pp. 52-53). Le Bon
quotes Agassiz to the effect that Brazil is undergoing degen-
eration on account of the large number of half-breeds in the
population, cross-breeding being fatal to the best qualities of
whites, blacks and Indians, the peoples concerned. It should
be said that this view of Le Bon's is held by only a small
minority of those who have discussed the question.
Baker's opinion ('08) concerning the relative capacity of
the mulatto and the pure negro does not seem to be very
decided one way or the other. He points out that a number
of leading negroes, as Washington, Du Bois, Douglass, Chest-
nutt, Braithwaite, Tanner and Terrell are mulattoes. In-
deed, "Most of the leading men of the race to-day in every
line of activity are mulattoes." ('08, p. 173). But on the
90 THE PSYCHOLOGY OF THE NEGRO.
other hand, such negro leaders as Vernon, Miller, Dunbar,
Price and Mason are probably pure-blooded. He claims that
to be a mulatto is to be neither a negro nor a white, but is to
have the ambitions and hopes of both races. Mulattoes and
negroes keep together on account of social pressure from
the whites. As to the number of mulattoes, Baker writes:
"From my own observation and from talking and correspond-
ing with many men who have had superior opportunities for
investigation, I think it safe to say that between one-fourth
and one-third of the Negroes in this country at the present
time have a visible mixture of white blood It is probable
that 3,000,000 persons out of the 10,000,000 population are
visibly mulattoes." ('08, p. 153). The proportion of mulattoes
is stated to be much larger in the North than in the South, and
the census figures are mentioned as being unreliable.
In a discussion of the political status of the negro, Stone
(*08) argues that a distinction should be drawn between the
pure negro and the mulatto. "There can no longer be a ques-
tion as to the superior intelligence of the mulatto over the
Negro — of his higher average potential capacity." ('08, p.
401). The leaders of the colored race, says Stone, have been
mulattoes, and this has been true in such places as Jamaica,
Santo Domingo, Haiti, South Africa and Liberia, as well as
in the United States. The exceptional blacks of pure blood
who have attained prominence were generally not descended
from true negroes at all. Their ancestry is to be found in
those stocks, such as the Fulah and others of high type, that
were brought from Africa as slaves in small numbers along
with the mass of true negroes.
From these abstracts it is evident that there is very little
definitely known as to the relative merits of pure negroes and
mulattoes. Of opinion, based more or less closely upon ob-
servation, there is a great deal. But there has been no seri-
ous attempt made to attack the problem from an experi-
mental or scientific standpoint. The views of men are
uncertain as to the relative abilities of whites and negroes;
it is to be expected that they will be much more uncertain
when they deal with sub-classes within the colored group.
The Classification
In the present investigation the negroes tested were divided
into four classes on the basis of racial purity as indicated
COMPARISON OF SUB-CLASSES OF NEGROES. 91
by color of skin, hair texture and general facial and cranial
conformation, the main emphasis being placed upon color.
The four classes were pure negroes, negroes three-fourths
pure, mulattoes proper, and quadroons. Of course there were
probably included in the classification some negroes who did
not belong, strictly speaking, in any of these classes. A few
octoroons, for example, may have been present, or a few
persons who were of seven-eighths pure negro stock. Such
cases were placed in the class which seemed to fit their status
best, and it is not thought that any constant error resulted
from this procedure.
It is also probable that errors were made in the classifica-
tion. Certain individuals may have been placed in a class too
near the pure negroes or too near the pure whites. But here
again the incorrect classifications would tend to balance each
other, and it is improbable that a constant error in any direc-
tion resulted. The effect of the overlapping of the classes
would be to lessen the differences found between them.* Con-
sequently it follows that in so far as the classification was in-
accurate, the real differences were greater than those indicated
by the scores.
In setting forth the results of the tests, the four classes
mentioned are adhered to. But in order to make the classifi-
cation still less subject to error, and to secure a larger number
of subjects in each class, the pure and the three-fourths pure
negroes are grouped together, and the mulattoes and the quad-
roons are grouped together, and the results are given sep-
arately in all cases for the two resulting classes as well as
for the original four. The difference in amount of white
blood between these two classes is greater than that between
any two classes of the four-class division, and the difference
between the scores of the combined pure and three-fourths
negroes and the combined mulattoes and quadroons should be
correspondingly greater than that between the classes of the
original division. This we shall find to be the case. And it
*It seems to the writer that probably the greatest chance for
erroneous classification occurred between the pure negroes and the ne-
groes three-fourths pure. It is not unlikely that differences in color be-
tween various stocks of pure negroes may have caused some com-
paratively light-colored individuals of this class to be counted as three-
fourths pure; and some three-fourths pure individuals of unusually
dark native stock may have been classed as pure-blooded. This suppo-
sition is borne out by the fact that the differences revealed by the
tests between the pure and the three-fourths pure negroes were less
than the differences between the other classes.
92 THE PSYCHOLOGY OF THE NEGRO.
should be noted in this connection that the class composed
of mulattoes and quadroons is very predominantly mulatto,
since the quadroons were few in number. This fact obviously
makes the difference found between mulattoes and quadroons
combined and pure and three-fourths negroes combined less
than it really is.
It should be said that the classification of the negroes was
made by the writer, who had had considerable experience
with negroes, at the time the tests were administered. None
of the subjects was previously known to him, and he is aware
of no circumstance that could have influenced the classifica-
tion in addition to the basis previously adopted. The sub-
jects seemed to fit into the various classes both naturally and
easily, and doubt as to the correctness of a classification was
so infrequent as to be negligible.
Numbers and Ages
The negroes tested in Fredericksburg and Newport News
were so few that the results from those cities were not used
in this intra-racial study. There was not a sufficient num-
ber of each of the four classes in either city to enable results
to be computed for any year or any grade. As in the gen-
eral comparison between whites and negroes, results from
only one subject were not considered.
The 319 negroes tested in Richmond fell into the different
classes numerically as shown in Tables 33 and 34, which give
the numbers by age and sex and by grades. The three high-
est and the two lowest years are not used in the comparisons
on account of the small number of pupils in them. It may
be noted that the largest class is composed of mulattoes, the
smallest of quadroons, and that the classes of pure negroes
and three-fourths pure negroes are of about equal size. The
mulattoes and quadroons together constitute 52 per cent, of
the total; the pure and three-fourths negroes together con-
stitute 48 per cent, of the total. In the elementary school
the mulattoes and quadroons are 46 per cent, of the total
number; in the high school the mulattoes and quadroons are
59 per cent, of the total number. There is thus a larger pro-
portion of light-colored negroes in the high school than in the
elementary school. And in the grades tested as a whole
there is a larger percentage of negroes of mixed blood than
there is in the city at large, as shown by the census figures.
COMPARISON OF SUB-CLASSES OF NEGROES.
93
These facts as to the relative numbers of pure and mixed
bloods in the school system indicate that the schools select
colored persons of partly white lineage to a greater extent
than they select pure negroes, and that as the grades advance
the selection becomes more pronounced. This would imply
that mulattoes in general are of greater ability and ambition
than are pure negroes. And the fact that there is a larger
proportion of light-colored negroes in the high school than in
the elementary school would partly explain the relatively
greater ability of high school negroes that was found in the
general comparison between white and colored subjects.
Mixed bloods, as will be shown, are of greater ability, and
there are proportionately more of them in the upper grades.

94 THE PSYCHOLOGY OF THE NEGRO.
The ages of the different classes of negroes in the various
grades are given in Table 35, and the differences between the
age of each class and the age of white pupils of the same
grade — the white pupils in question being those tested in
Richmond — are given in Table 36. This latter table shows
that the pure negroes were .69 of a year older than the white
pupils; the three-fourths pure negroes were .32 of a year
older; the mulattoes were .29 of a year older; and the quad-
roons were .07 of a year younger. The pure and three-fourths
negroes combined were .51 of a year older than the whites;
the mulattoes and quadroons combined were .23 of a year
older. These figures are significant. They show that the
darker negroes were slower in reaching a given grade than
were those of lighter color. The differences are small, and
are subject to variation from grade to grade. But the aver-
age differences, which are here quoted, are uniformly greater
for the darker negroes, and the probable errors are not large
enough to invalidate the significance of this uniformity.

Standing in the Tests
The tests used in this comparison are the mixed relations,
Tests I and II, and the completion. These tests revealed
marked differences between whites and negroes as a whole,
and they are therefore well adapted to bring out any differ-
ences that may exist between the various classes of negroes.
The maze and cancellation tests did not show any considerable
differences in the general inter-racial comparison, and they
are consequently not employed here. ^
In setting forth the results of the tests the same order is
followed as in the preceding chapter. In the case of each test,
first are given the actual scores, with their average devia-
tions, classified by age and sex and by grades. Then appear
graphs based upon these scores. The graphs are drawn only
for the two-division classification — that of pure and three-
fourths negroes combined and mulattoes and quadroons com-
bined. The scores of the white pupils tested in Richmond
are included in the graphs for the sake of comparison. Fol-
lowing the graphs are the tables in which the comparisons
are made. In each instance the score of the colored subjects
is compared with that of the corresponding white pupils.
The actual differences between the scores are given; the
percentage of the score of the whites that was obtained by
the negroes next appears; and lastly are shown the per-
centages of the two-division classification that reach or ex-
ceed the average score of the whites. The averages of the
various ages and grades, with their probable errors, appear
in each table of comparison.
Tables 37 and 38 give the scores in the mixed relations test.
Figures 16-21 present these scores in graphic form. Tables
39-43 make the comparisons. From these latter tables the
following facts appear.

In Test I, in the case of boys, classified by age, the pure ne-
groes obtained 58.8 per cent, of the score of the whites; the
three-fourths pure negroes obtained 72.2 per cent, of the
score of the whites ; and the mulattoes obtained 78.5 per cent,
of the white score.* When the boys are grouped into two
classes, pure and three-fourths combined and mulattoes and
quadroons combined, the former class is shown to have ob-
tained 62.0 per cent, of the score of the whites while the latter
class obtained 83.5 per cent, of the white score.
The girls in Test I, classified by age, obtained the following
percentages of the white score: Pure negroes, 68.0; three-
fourths pure negroes, 71.3; mulattoes, 87.5; quadroons, 99.0.
When the girls are arranged in two classes the results are
as follows; The pure and three-fourths negroes combined
scored 72.0 per cent, as high as the whites; the mulattoes
and quadroons combined scored 89.3 per cent, as high as the
whites.
The grade comparison for Test I shows that the pure ne-
groes, boys and girls together, scored 73.3 per cent, as high
as the whites ; the three-fourths pure negroes scored 74.6 per
cent, as high; the mulattoes scored 81.6 per cent, as high;
the quadroons scored 87.9 per cent, as high as the whites.
The two-division classification by grades shows that the pure
and three-fourths negroes obtained 72.9 per cent, of the white
score, and that the mulattoes and quadroons obtained 82.8
per cent, of the white score.
The percentages of negroes reaching or exceeding the aver-
age of the whites were as follows in Test I : Boys — ^Pure and
three-fourths combined, 17.0; Mulattoes and quadroons com-
bined, 38.5. Girls — ^Pure and three-fourths combined, 25.5;
*There was not a sufficiently large number of quadroon boys to be
included as a separate class in the tables of comparison. There were
only five such boys in all, and only two of them were in any one age
group, namely, age 14. These two scored higher than any of the other
classes of negroes, but of course a result from such a small number is
practically worthless. The quadroon boys are included in the groups
of combined mulattoes and quadroons, however, and in the grade groups
of quadroons, which contain both boys and girls.

These figures show that in Test I the size of the score made
by the negroes varies directly with the amount of their white
blood. As judged by the averages, this is true without excep-

tion for both boys and girls and in both the age and the grade
classifications. The size of the probable errors and the con-
stancy of the results renders the differences reliable. In the
two-division classification the differences are larger than in
the four-division classification, as was to be expected, and the
results here are especially reliable when the size of the proba-
ble errors is considered.

We may conveniently average the percentages obtained by
the boys, girls and grades in each class. When this is done
the scores for the four classes of negroes, in terms of per-
centages of the score of whites, are as follows : Pure negroes,
66.7.; negroes three-fourths pure, 72.7; mulattoes, 82.5; quad-
roons, 93.4. The scores of the two-division classification, in
the same terms, are: Pure and three-fourths negroes, 69.0;
mulattoes and quadroons, 85.2. Averaging the percentages
of boys, girls and grades that reached or exceeded the average
score of whites, we find that 22.6 per cent, of the combined
pure and three-fourths negroes, and 39.4 per cent, of the com-
bined mulattoes and quadroons reached the white average.
In Test II the same situation occurs. The percentages of
the score of the whites obtained by the pure, the three-fourths
pure and the mulatto boys were 63.8, 64.5 and 81.8, respec-
tively. For the girls, the percentages obtained by the pure
negroes, the negroes three-fourths pure, the mulattoes and
the quadroons were, respectively, 64.7, 70.7, 78.5 and 93.0.
For the grades, the percentages, in the same order, were 73.3,
72.0, 79.2 and 83.2.*
The combined pure and three-fourths pure negroes and the
combined mulattoes and quadroons scored, in Test II, the fol-
lowing respective percentages of the score of the whites:
Boys— 62.7 and 87.7 ; Girls— 69.0 and 80.5 ; Grades— 72.7 and
79.9.
*It should be noted that in the comparison by ^ades in Test II the
pure negroes scored 1.3 per cent, higher than those three-fourths pure.
In the grade comparison of the completion test the pure negroes also
scored higher, by 2.0 per cent., than the three-fourths negroes. These
are the only instances in which subjects with a greater amount of white
blood were inferior to those with a lesser amount. As was previously
pointed out, comparisons by grades are not as likely to reveal marked
or reliable differences as are comparisons by ages; and as was also
pointed out, the classes of pure and three-fourths pure negroes may
not have been as well separated as the other classes.
COMPARISON OF SUB-CLASSES OF NEGROES. 105
The percentages of negroes reaching or exceeding the aver-
age of the whites in Test II were as follows : Boys — Pure and
three-fourths, 19.2; Mulattoes and quadroons, 46.8. Girls —
Pure and three-fourths, 27.2; Mulattoes and quadroons, 42.8.
Grades — Pure and three-fourths, 30.4; Mulattoes and quad-
roons, 37.5.
If we average for Test II the percentages obtained by the
boys, girls and grades in each class, we find that the pure
negroes obtained 67.3 per cnt. of the score of the whites;
that the three-fourths pure negroes obtained 69.1 per cent,
of the score of the whites; that the mulattoes obtained 79.8
per cent, of the white score ; and that the quadroons obtained
88.1 per cent, of the white score. The pure and three-fourths
negroes, boys, girls and grades, scored 68.1 per cent, as high
as the whites; the mulattoes and quadroons, boys, girls and
grades, scored 82.7 per cent, as high as the whites. Aver-
aging the percentages of boys, girls and grades that reached
or exceeded the average white score, we find that 25.6 per
cent, of the pure and three-fourths pure negroes reached the
white average; and that the white average was reached by
42.4 per cent, of the mulattoes and quadroons.
The results of the completion test appear in Tables 44 and
45 and in Figures 22-24. The comparisons are made in Ta-
bles 46-50. These latter tables show the following results:
In the case of boys, the pure negroes obtained 65.3 per
cent, of the score of the whites; the three-fourths pure ne-
groes obtained 76.2 per cent. ; and the mulattoes obtained 79.2
per cent. For girls, the percentages for the four classes of
negroes, pure, three-fourths pure, mulattoes and quadroons,
were, respectively, 74.3, 77.7, 81.8 and 95.8. For grades, the
percentages were: Pure negroes, 81.4; three-fourths pure, 79.4;
mulattoes, 82.9; quadroons, 92.2. When the pure and three-
fourths pure negroes and the mulattoes and quadroons are
grouped together, it appears that the pure and three-fourths
pure boys scored 68.7 per cent, as high as the whites, and
that the mulatto and quadroon boys scored 82.0 per cent, as
high as the whites. The girls, purs and three-fourths pure,
obtained 77.3 per cent, of the white score ; and the girls, mu-
lattoes and quadroons, obtained 83.5 per cent, of the white
score. In the case of the grades, the pure and three-fourths
pure negroes scored 80.2 per cent, as high as the whites, and
the mulattoes and quadroons scored 83.4 per cent, as high.

108 THE PSYCHOLOGY OF THE NEGRO.
If we average the percentages for boys, girls and grades,
we find that the pure negroes scored 73.7 per cent, as high as
the whites, the three-fourths pure negroes scored 77.8 per
cent, as high, the mulattoes scored 81.3 per cent, as high, and
the quadroons scored 94.0 per cent, as high as the whites.
The pure and three-fourths pure negroes, combined, obtained
75.4 per cent, of the white score; the mulattoes and quad-
roons, combined, obtained 83.0 per cent, of the white score.
In terms of the percentage of negroes reaching or exceeding
the average of the whites, the results for boys, girls and
grades are: Pure and three-fourths pure negroes, 22.7 per
cent.; Mulattoes and quadroons, 34.7 per cent.

110 THE PSYCHOLOGY OF THE NEGRO.
It is evident that the results from the completion test show
the same general standing for the four classes of negroes
that was brought out by the mixed relations test: the sub-
jects with the greater amount of white blood were superior.
And the size of the probable errors, particularly in the case
of the two-division classification, renders the results reliable.
The standing of the various classes of negroes in the mixed
relations tests, I and II, and in the completion test may be
averaged. When this is done the figures show that the pure
negroes scored 69.2 per cent, as high as whites; that the
three-fourths pure negroes scored 73.2 per cent, as high as
whites; that the mulattoes scored 81.2 per cent, as high as
whites; and that the quadroons obtained 91.8 per cent,
of the white score. The pure and three-fourths pure negroes,
combined, obtained 70.8 per cent, of the score of the white
subjects; the mulattoes and quadroons, combined, obtained
83.6 per cent, of the score of the whites.
This suggests that it is sometimes questioned as to how far
external appearances are indicative of racial purity. It is
held that a certain proportion of the offspring of mixed races
will not show the blood characteristics which their heredity
would seem to warrant. This may be true, and the Mendelian
laws of inheritance may furnish a basis for such variation.
But in the main, children conform closely to the character-
istics of their parents in all respects, and such variations as
occur will offset each other in any considerable number of
persons, and leave the group type predominant. Certainly
the results here obtained indicate that the correlation between
skin color and racial purity is high.
There was apparently nothing except native racial ability
that could bring about the results found herein for the differ
ent classes of negroes. It is possible, indeed, that the lighter
negroes were of a better social class than the darker. But if
this was true, it must be that the mixed bloods attained to a
better social standing because of their greater capacity. For
among negroes in general there are no considerable social dis-
tinctions based on color. A colored person is a colored person,
whether he be mulatto or negro, and all mingle together as
one race. Pyle, in a quotation previously given, reports that
of the negroes tested by him, those of better social class made
higher scores. And it would not be surprising if it were
found that mulattoes constituted the bulk of the superior
COMPARISON OF SUB-CLASSES OF NEGROES. HI
social class, and only a minority of the inferior class. It
would be surprising, in view of the results found here, if it
were otherwise. But any such distribution should be ascribed
to the greater inherent capacity of negroes of lighter skin.
No social or material gulf, such as that which separates the
white and colored races in this country, is to be found among
the negroes themselves. Such distinctions as there are, and
however based, are very minor as compared with the great
inter-racial distinction. And to a marked degree the general
environment of colored children is the same for all. With no
great variations, they all attend the same schools, live in the
same neighborhoods, grow up in the same home surroundings,
share the same cultural advantages, meet the same opportuni-
ties, undergo the same experiences. They live almost in a
world of their own, which is but one stratum or level of our
mixed society. This is particularly true of the selected group
of negroes found in the upper grades of the schools. And yet
the differences, as revealed by the mental tests, between the
pure negroes and the mulattoes, on the one hand, and the mu-
lattoes and the whites, on the other, are not unlike in amount.
The mulattoes who, with the pure negroes, live in the com-
paratively uniform colored environment, which is so greatly
different from the white environment, are yet almost as near
to the whites as to the pure negroes when put to psychological
tests. This fact becomes especially noteworthy when it is
considered that the greater number of mulattoes are probably
descended from an inferior element among the whites, and
probably from an inferior element among the negroes also.
Such considerations indicate that it is a native ability and
not an acquired capacity that differentiates the mixed and the
pure negroes, and that skin color is its outward sign. They
also indicate that the tests used are primarily tests of native
capacity, and that consequently the differences found between
whites and negroes as a whole are innate differences.
Comparative Variabilities
In recent years a number of writers have called attention
to the importance of differences in the variability of groups
from their central tendencies. It is pointed out that two
groups, as two races or two sexes, may be of the same aver-
age capacity, but that if one of these groups is more variable
than the other, certain significant differences will appear.
112 THE PSYCHOLOGY OF THE NEGRO.
The more variable group will produce a greater number of
individuals of very high capacity and also a greater number
of very low capacity; within the less variable group there
will be more conformity to the group type and less diver-
gence toward the extremes. In the former case there will be
a greater number of geniuses and of moral heroes than in the
latter, and also a greater number of idiots and of moral de-
generates. This will result in marked differences in the rela-
tive attainments of the groups as wholes. Progress depends
upon the few who stand out from the crowd and invent new
and better ways of doing things. The few conceive and the
many appropriate their conceptions, in all realms of human
activity. In mechanical and material progress, in science, in
art, in literature, in religion, in politics, it is the geniuses
who make progress possible. And it follows that a variable
group, other things being equal, will achieve a higher type
of civilization than one which is less variable.
In discussing this matter, Woodworth writes as follows:
"The distribution of a trait is for some purposes more im-
portant than the average. Let us suppose, for instance, that
two groups were the same in their average mental ability,
but that one group showed little variation, all of its mem-
bers being much alike and of nearly the average intelligence,
while the other group showed great variability, ranging be-
tween the extremes of idiocy and genius. It is evident that
the two groups, though equal on the average, would be very
unequal in dealing with a situation which demanded great
mental ability. One master mind could supply ideas for the
guidance of the group, and his value would far outweigh the
load of simpletons which the group must carry." ('10, p. 2).
Thomdike ('10) writes to the same effect. He claims that
men are more variable than women, and that on this account
the greater part of the genius and the stupidity of the world
is found among men. In discussing racial capacity, he says:
"The comparison in variability is, as in the case of the sexes,
of great practical importance. The ability of a hundred of
its most gifted representatives often counts more for a na-
tion's or a race's welfare than the ability of a million of its
mediocrities." '10, pp. 53-54).
While the importance of variability is thus recognized,
there is as yet very little evidence bearing upon the relative
variability of diffrent races. In summing up the psychologi-
COMPARISON OF SUB-CLASSES OF NEGROES. 113
cal results available in 1910, Wood worth wrote as follows:
"The dead level of intelligence, which is sometimes supposed
to obtain among backward races, is not borne out by psycho-
logical tests, since individual differences are abundantly found
among all races, and, indeed, the variability of different groups
seems, from these tests, to be about on a par." ('10, p. 15).
Hrdlicka ('98) and Le Bon ('98), as quoted in Chapter I,
claim that in physical traits whites are more variable than
negroes. Strong ('13) states, as previously quoted, that the
lighter-colored negroes among the 122 tested by her were
more variable than those of darker color. Mayo, after dis-
cussing the variabihty of whites and negroes, writes as follows
concerning the groups studied by him: "In our own study of
the two groups of high school pupils, however, the fact of
greater racial mental variability is not at all pronounced,
though the whites were slighly more variable. The average
deviation of the white group from their mean scholastic at-
tainment was 7, while that of the colored group was 6.5."
('13, p. 69). In addition to the somewhat inconclusive find-
ings of these writers, there do not seem to be any reliable
measurements bearing upon the problem.
At present we have no good method of measuring the vari-
ability of groups. Of course the actual variabihties may be
compared in such terms as the average deviation or the
probable error. But this will be misleading if the groups
differ considerably in their standing in the capacity in ques-
tion. A higher average standing generally implies a greater
average deviation. If an average score of 30 has an average
deviation of 10, an average score of 20 in the same trait will
have a smaller deviation. The actual size of the deviations
must therefore be considered in connection with the size of
the average scores.
In order to overcome this difficulty, Pearson has proposed
that the deviations should be divided by the group averages
before a comparison is made. But this procedure is open to
the objection that it is not certain that deviations vary in
proportion to the size of the central tendencies from which
they are derived. There is reason to believe that they more
nearly vary in proportion to the size of the square roots of
the central tendencies. Accordingly Thorndike ('04) has
suggested that actual variabilities should be divided by the
114 THE PSYCHOLOGY OF THE NEGRO.
square roots of averages rather than by the averages them-
selves.
Since there is thus no single reliable measure of variability,
our procedure in the following comparisons will be to set
forth the average deviations, the Pearson coefficients, i.e.,
the deviations divided by the averages, and the Thorndike co-
efficients, i.e., the deviations divided by the square roots of
the averages. And since none of these methods is wholly
free from objection, the average of all three is presented in
each case as a combined coefficient.
The variabilities are given in this manner for the various
classes of colored subjects in terms of percentages of the
variability of white subjects of the same ages or grades.
The variability of the whites is therefore to be considered
as 100 in all cases. The figures for the separate ages and
grades are omitted for the sake of brevity, and only the aver-
ages of the different ages and grades are presented. The
actual deviations from which the figures are derived are
shown in the tables in this and the foregoing chapters which
set forth the scores. Only the Richmond pupils are treated
in the comparisons.
Table 51 shows the relative variabilities of the different
classes of subjects in the age at which they reached the school
grades studied. From the averages it appears that the pure
negroes, the three-fourths negroes, the mulattoes and the
quadroons were 66, 91, 87 and 74 per cent., respectively, as
variable as the whites; that the pure and three-fourths ne-
groes combined and the mulattoes and quadroons combined
were, respectively, 83 and 95 per cent, as variable as the
whites; and that the colored pupils of all classes combined

had 89 per cent, of the white variability. The average devia-
tions, the Pearson and the Thorndike coefficients all give
practically the same result: the negroes were less variable
than the whites.
The uniform behavior of the figures for age variability is
in contrast with the more uncertain nature of those which
show the variability of the scores in the tests. Tables 52-55
make the test comparisons. Relying upon the averages, it
appears that the pure negro boys are 72, 106 and 63 per cent,
as variable as the white boys in the Mixed Relations Test I,
the Mixed Relations Test II and the completion test, respec-
tively ; that the pure negro girls are 104, 98 and 84 per cent.
as variable as the white girls in these respective tests; and
that the pure negroes when compared by grades are 85, 85
and 89 per cent, as variable as the whites in these tests. The
figures which show the relative variability of the three-fourths
pure negroes in the three tests, in the order mentioned, are
as follows: Boys— 69, 86 and 82 per cent.; Girls— 101, 88 and
56 per cent. ; Grades — 99, 110 and 85 per cent. The relative
variability of the mulattoes in the three tests is: Boys — 90,
87 and 115 per cent.; Girls— 123, 104 and 102 per cent.;
Grades — 109, 102 and 100 per cent. The percentages for the
quadroons are: Girls — 118, 84 and 57; Grades — 69, 44 and
47. These figures are not subject to any sure interpreta-
tion. But it appears to be very probable that the pure and
the three-fourths pure negroes are less variable than whites,
and that the quadroons are also less variable. The com-
paratively small number of quadroons, however, may be a
factor here. The mulattoes appear to have a variability as
great as that of the whites.

118 THE PSYCHOLOGY OF THE NEGRO.
The combined pure and three-fourths pure negroes, when
compared with whites, have relative variabilities as follows
in the Mixed Relations Test I, the Mixed Relations Test II and
the completion test, respectively: Boys — 84, 109 and 83 per
cent.; Girls — 104, 101 and 78 per cent.; Grades — 96, 101 and
92 per cent. The figures for the combined mulattoes and
quadroons show that they have the following relative varia-
bilities in the three tests: Boys — 98, 99 and 111 per cent.;
Girls— 121, 96 and 98 per cent. ; Grades— 103, 95 and 92 per
cent. It is thus probable that the mulattoes and quadroons
are slightly more variable than the pure and three-fourths
pure negroes, but here again the results are not certain. Both
classifications appear to have not far from the white varia-
bility.
When all classes of negroes are grouped together and com-
pared with whites, they show the following relative variabili-
ties in the three tests mentioned: Boys — 107, 114 and 97 per
cent. ; Girls — 113, 101 and 80 per cent. ; Grades — 102, 101 and
93 per cent. The colored subjects as a whole had a greater
rather than a less variability than the white.
This last statement is reinforced by the figures from the
maze and cancellation tests. In the maze test, the colored
boys were 106 and 100 per cent, as variable as the white boys
in touches and distance respectively; the colored girls were
138 and 137 per cent, as variable as the white girls in touches
and distance; the colored grades were 100 and 99 per cent.
as variable as the white in touches and distance. In the can-
cellation test, the figures showing the relative colored varia-
bility in omissions and cancellations, respectively, were:
Boys — 128 and 104 per cent.; Girls — 133 and 120 per cent.;
Grades — 135 and 98 per cent. The negroes in these tests
were more variable than the whites, all classes of colored sub-
jects being grouped together.
In addition to these figures from Tables 52-55, attention
should be called to those in Tables 39-43 and 46-50 as indica^
tions of the relative variability of the different sub-classes
of negroes. These tables give the probable errors of the
scores made by the various classes of negroes when compared
with whites. The probable errors show a marked uniformity
in being smaller for the darker^colored negroes and larger for
those of lighter color. That is, they show that in the case
of the darker negroes the separate age and grade groups va-
ried less with respect to their own average difference from
COMPARISON OF SUB-CLASSES OF NEGROES. 119
corresponding white age and grade groups. Now this greater
constancy among the differences for the separate ages and
grades of darker negroes might have been due to chance if it
had occurred only infrequently. For example, if the scores
of four white grades are 40, 50, 40 and 50, and the scores of
four corresponding colored grades are 20, 30, 20 and 30, the
differences between these grades will be 20, 20, 20 and 20, and
the probable error will be zero. But if the four corresponding
colored grades have scores of 30, 20, 30 and 20, the differences
will be 10, 30, 10 and 30, and the probable error will be 5. The
actual scores and the actual average differences are the same
in the two cases, but a chance arrangement in the correspon-
dence of the scores alters the probable errors. And if the
difference from the whites of first the lighter and then the
darker negroes had the smaller probable error, we could at-
tach no significance to the fact. But the smaller probable
error in the case of the darker-colored negroes occurs with a
uniformity which cannot be ascribed to chance. And we must
suppose that it is due to a greater constancy in the scores
of the individuals within the darker age and grade groups
themselves. This greater constancy of the individual scores
would be reflected in the greater constancy of the separate
group scores and hence in the smaller probable error of such
scores. And consequently we have a further indication of the
smaller variability of the negroes of comparatively pure
blood.
On the whole, it appears that the pure negroes, the three-
fourths pure negroes and the quadroons varied less than did
the whites ; that the mulattoes did not differ from the whites
in variability ; that the combined pure and three-fourths pure
negroes and the combined mulattoes and quadroons had not
far from white variability, and that the latter class varied
slightly more than did the former; that the colored subjects
of all classes together had a greater variability than the white.
But these conclusions are only approximately certain. The
average coefficients upon which they are based are not uni-
form in their import, and the separate coefficients taken by
themselves are not more so. If we consider only the actual
variabilities, the white are clearly more variable than the col-
ored subjects, except in the cancellation test, and the sub-
classes of negroes, particularly those of darker color, are
much less variable than the negroes as a whole. It is in-
teresting to note that the colored girls had generally a greater
120

variability than the colored boys when compared with whites.
Figures 25-28 are inserted to show graphically the relative
distribution of the two races in one test — ^the completion.
This distribution is fairly typical of that found in the other
tests. All classes of negroes are included. In the graphs
the boys and girls are treated separately, but the elementary
pupils are grouped together, as are the high school pupils.

This procedure is permissible on the ground that within
either the elementary or the high school grades tested the
pupils do not differ significantly from age to age, as was
shown in Chapter III. The number of pupils obtaining a
given score was in all cases reduced to a percentage of the
total number in the distribution.
From the graphs it appears that the white elementary boys
and the white elementary girls are probably more variable
than the colored, but that the colored subjects, particularly
the boys, are probably the more variable in the high school.
But no certain conclusion as to racial variability can be
reached. It appears more certain that the boys are more
variable than the girls. Incidentally, attention may be called
to the comparison of racial ability revealed by the graphs.
They make plain the extensive overlapping of the scores of
the whites and negroes. Even where there is a great differ-
122 THE PSYCHOLOGY OF THE NEGRO.
ence between the average scores of the two races and where
only a small percentage of the negroes reaches or exceeds the
average of the whites, the overlapping is great and should
not be overlooked.
It may finally be remarked with regard to the relative vari-
ability of whites and negroes, that it would not be at all sur-
prising if groups of so-called negroes were definitely shown to
be more variable than comparable groups of whites. For the
groups that are generally called negroes are composed of in-
dividuals ranging from pure negroes to persons almost white,
and it would be reasonable to suppose that such groups would
vary more than would homogeneous white groups. They are
not composed of one race but of two. Of course it may be
that the variability of the negro race falls entirely within
the extremes of variability of the white, but this would not
offset the greater average deviation that would be caused by
the relative tendency to bi-modality, or at least to flatness
of distribution, in a mixed negro and mulatto group. This
consideration should be taken into account in all studies of
the variability of whites and negroes. It would be interest-
ing and useful to know whether colored people, negroes and
mulattoes together, vary as much as do whites. But this
information would not inform us as to the relative variability
of the white and negro races.
CHAPTER V.
CONCLUSION
By way of summary of the various considerations which
have come to light in this study, we may say that the average
performance of the colored population of this country in such
intellectual work as that represented by the tests of higher
capacity, appears to be only about three-fourths as efficient
as the performance of whites of the name amount of trainings'
It is probable, indeed, that this estimate is too high rather
than too low. The groups of whites and negroes studied are
not typical of the white and colored populations in general;
their ability is undoubtedly considerably above the average.
But the negroes were probably farther above their racial av-
erage than were the whites. If one were to test the capacity of
the unselected masses of negroes, with their much smaller per-
centage of white blood, and make a comparison with unselect-
ed masses of whites, the results would almost certainly reveal
greater racial differences than those found herein.
All of the experimental work which has been done has
pointed to the same general conclusion. The bulk of it has
shown a greater racial difference than that found in Rich-
mond, and has been more comparable in its results with the
findings recorded for Fredicksburg and Newport News. The
opinions of the great majority of those who have come into
contact with the negro, and the views of nearly all of those
who have studied the question from standpoints other than
experimental, are in substantial agreement with the quantita-
tive evidence.
In the present state of the advancement of science it does
not seem possible to make adequate tests of those vastly im-
portant qualities which are included in the feeling and dy-
namic, rather than in the intellectual, side of mental life. It
is the common opinion that the negro differs more from the
white in such traits than in intellect proper. His emotions
are generally believed to be strong and volatile in their mani-
123
124 THE PSYCHOLOGY OF THE NEGRO.
f estations ; whether this is due to their intrinsic nature or to a
lack of restraint, is an untouched problem. Instability of
character is ascribed to the negro, involving a lack of fore-
sight, an improvidence, a lack of persistence, small power of
serious initiative, a tendency to be content with immediate
satisfactions, deficient ambition. But the evidence that such
characteristics constitute a true racial difference cannot be
called conclusive, and the psychological causes underlying
them have not been adequately investigated. Along with
high emotionality and instability of character, defective mo-
rality is held to be a negro characteristic. This is as subject
to debate as are the other qualities, though it is apparently
supported by social statistics.* It may be that the total cir-
cumstances of his life are such as would lead to immorality
even were the negro possessed of the psychic nature of the
white man.
On the other hand, while it is impossible to arrive at an
exact knowledge of the relative amounts of such important
but intangible traits in the two races, it must be said that the
evidence of experience and observation cannot be disregarded.
Such evidence is often wholly unscientific and worthless, but
not always so. Strong and changing emotions, an improvi-
dent character and a tendency to immoral conduct are not
unallied. They are all rooted in uncontrolled impulse. And a
factor which may tend to produce all three is a deficient de-
velopment of the more purely intellectual capacities. Where
the implications of ideas are not apprehended, where thought
is not lively and fertile, where meanings and consequences
are not grasped, the need for the control of impulse will not
be felt. And the demonstrable deficiency of the negro in in-
tellectual traits may involve the dynamic deficiencies which
common opinion claims to exist.
The available evidence indicates that in the so-called lower
traits there is no great difference between the negro and the
white. In motor capacity there is probably no appreciable
*Statistics concerning the sexual immorality, as indicated by ille-
gitimate births, of whites and negroes in the District of Columbia have
recently been published by Ottenberg ('15). In 1912 and 1913 the total
of all births reported to the Health Department was 13,910, of which
number 1374, or approximately 10 per cent, were illegitimate. There
were four times as many illegitimate births of colored as of white chil-
dren reported, and yet the colored population was only about one-half
as large as the white. Statistics showing the very much larger per-
centage of negroes than of whites convicted of crime are too well known
to require quotation here.
CONCLUSION. 125
racial difference. In sense capacity, in perceptive and dis-
criminative ability, there is likewise a practical equality. It
is in the central elaborative powers upon which thought more
directly depends that differences exist, not in the simpler re-
ceptive and discharging functions. %t seems as though the
white type has attained a level of higher development, based
upon the common elementary capacities, which the negro has
not reached to the same degree".; From the nature of the men-
tal differences, one would infer that such neural differences
as may be found will probably be mainly in the constitution
of the cortical neurones, rather than elsewhere in the nervous
system.
While the intellectual performance of the general colored
population is approximately 75 per cent, as efficient as that of
whites, this figure is not true for different classes of negroes.
It is probably correct to say that pure negroes, negroes three-
fourths pure, mulattoes and quadroons have, roughly, 60, 70,
80 and 90 per cent., respectively, of white intellectual effici-
ency. If it were possible to distinguish these four classes of
negroes so accurately as to avoid overlapping, it is probable
that the differences revealed by tests would be greater rather
than less than those indicated by the figures.
The educational significance of the available facts is difficult
to determine. The negro's intellectual deficiency is regis-
tered in the retardation percentages of the schools as well as
in mental tests. /'And in view of all the evidence it does not
seem possible to Vaise the scholastic attainment of the negro
to an equality with that of the whitei It is probable that no
expenditure of time or of money would accomplish this end,
since education cannot create mental power, but can only de-
velop that which is innate.
The movement toward industrial education for the negro
finds sanction in the studies of his psychology. Without
great ability in the processes of abstract thought, the negro
is yet very capable in the sensory and motor powers which
are involved in manual work. And economy would indicate
that training should be concentrated upon those capacities
which promise the best return for the educative effort ex-
pended. Social conditions, of course, have been the main in-
centive to the growth of industrial education among negroes,
126 THE PSYCHOLOGY OF THE NEGRO.
and in themselves they are sufficient reason for emphasiz-
ing an intensely practical training. But the mental nature
of the negro gives reason for believing that this sort of edu-
cation is the only one which will avoid great waste. Dimin-
ishing educational returns will be more serious in the intel-
lectual than in the industrial education of the negro.
There is need of experiment to determine the relative ability
of colored and white persons in the intelligent handling of
concrete materials. All of the experiments so far undertaken
have dealt with thought material as represented by words
rather than by objects. Tests which involve mechanical ma-
nipulations have not been tried. It is possible that reasoning
based upon objects present to sense may not correlate highly
with reasoning based upon the mental representations of ob-
jects, and that the negro may therefore more nearly approach
the white in the former than he does in the latter sort of
thinking. The writer expects to undertake a series of experi-
ments upon the comparative intellectual ability of the two
races in mechanical tests, and if the difference between them
is less than that revealed by tests of a more literary nature,
additional sanction will be given to the reasonableness of in-
dustrial education.
But while it thus appears that for the colored population
as a whole a manual is more practicable than a literary educa-
tion, it must not be overlooked that there are individual col-
ored persons of great ability. The widely held doctrine that
the negro's mental growth comes to a comparative standstill
at adolescence does not find corroboration in the results of
tests. The groups so far tested, indeed, show that after
adolescence the negro more nearly approachs the white than
before. This is probably due to the fact that the adoles-
cent negroes tested are a more closely selected group
than those who have not reached adolescence. The adolescent
negroes in the schools have more white blood in them. And
racial differences at adolescence may exist in the feeling and
dynamic sides of mental life, which have not been tested. If
there are such differences they will most likely appear just
here. But so far as has been demonstrated, the negro's intel-
lectual development proceeds as rapidly after puberty as does
that of the white. Then, too, the variability of the negroes
and the overlapping of ability in the two races, make it neces-
sary to expect very able colored persons to be found in every
CONCLUSION. 127
large group. In the main, the most capable colored individ-
uals will be mulattoes, although there are fewer mulattoes
than pure negroes.
' v^ince comparisons between races are frequently made in
terms of the number of eminent men produced by each, it is
interesting to make a rough computation as to the number of
pure negroes, mulattoes and whites that may be expected to
demonstrate great ability in the United States. This com-
putation lays no claim to other than approximate validity.
It is based upon the "law of deviation from an average" as
employed by Francis Galton ('92, p. 22 ff.), and in making it
the variability of each class of the population is considered as
being the same. Of course, if the variability of pure negroes
is less than that of whites, as is probable, the number of very
able negroes will be less than is indicated by the following
figures.
We may take as our standard of eminence the one chosen
by Galton, viz., attainment so great that it is reached by only
one man in 4300. In each million men there are 248 persons
of this standing. Now there are approximately 18,000,000
white men, 1,600,000 pure negro men and 400,000 men who
are mulattoes in this country. Consequently, if all three
classes have the same ability, there will be 4464 eminent
white men, 397 eminent pure negroes and 99 eminent mulat-
toes.
But if we assume that pure negroes average 75 per cent,
of white ability and that mulattoes average 87.5 per cent, of
white ability, we find the following situation growing out of
the law of deviation from an average.* In a million of each
class of men, there will be 248 whites, 15 mulattoes and 1
l^ure negro who will attain the above-mentioned degree of
eminence. Considering the number of these three classes
*To carry out the computation based upon this assumption it is neces-
sary to postulate a zero point of ability, and the capacity of the lowest
idiot is taken as this zero point. That this may be done without violence
to the facts is indicated by the descriptions of idiocy given in works on
mental deficiency. Thus Tredgold ('08) writes of profound idiots that
their brief existence may almost be called vegetative. They are devoid
of instincts, they lie huddled in an ante-natal posture, food must be
placed in their mouths, and their life activities hardly extend beyond
respiration, assimilation and excretion. "They have eyes, but they see
not; ears, but they hear not; they have no intelligence and no conscious-
ness of pleasure or pain; in fact, their mental state is one entire nega-
tion." ('08, p. 171).
128 THE PSYCHOLOGY OF THE NEGRO.
in the total population, there will be 4464 eminent whites,
6 eminent mulattoes and 2 eminent negroes in the United
States.
These figures are suggestive. If we take it that there are
4464 eminent white men in America, there are certainly not
397 pure negroes and 99 mulattoes of the same degree of
eminence. There are more nearly 6 mulattoes and 2 pure
negroes to 4464 eminent whites. Definite figures are not ob-
tainable, but such lists of men of achievement as have been
compiled accord with the latter set of figures far more closely
than with the former.
Of course it may be held that social conditions make it im-
possible for colored ability to assert itself. There may be
potentially eminent men among the negroes who are not able
to attain their commensurate achievement on account of en-
vironmental conditions. On the other hand, it may be said
that the best opinion, as that of Galton, holds that eminence
is independent of circumstance; that innate power can be
neither crushed nor created by adverse or favorable influences.
And it may be further contended that ability among negroes
is all the more readily recognized just because of their gen-
erally low level of racial attainment. A man of mark among
them stands out becauuse of his rarity, and his opportunities
are increased because of this recognition.
As an indication of the greater ability of mulattoes than
of pure negroes, it may be remarked that such lists as we
have of colored leaders, e.g., those quoted in Chapters I and
IV, show a larger proportion of men of mixed than of unmixed
blood. And this despite the fact that there are probably
four times as many pure negroes as mulattoes in the country.
Although the available facts are very few and inexact, such
as they are they serve to justify rather than to controvert
the deductions from the law of variability. And in so far as
the deductions are borne out, the assumed racial inequality
upon which they are based is confirmed.
There are few more controversial subjects than that of the
outlook for the negro race in America, and it is not within
the province of this monograph to attempt a discussion of
the topic. But it may not be out of place to mention certain
considerations that have presented themselves. Conclusions
concerning the negro's possibilities in this country are fre-

quently drawn from a study of the various small negro re-
publics, such as Haiti, Santo Domingo and Liberia, and opin-
ions so arrived at are not without their value. Yet there are
differences between the position of the American negro and
that of the negro in the isolated states in question. It should
be noticed that the number of American negroes is larger
than the number in any of the negro republics. Progress de-
