There is a slight tendency for salesmen to make a greater number of at- tempts at disguising their handwriting. In addition to the scores regularly obtained from the test series, the following measures were obtained. Agreements Between Checks in Parts 3 and 9. This score was obtained at the suggestion of L. D. Anderson, as a possible meas- ure of conceit. The score is the number of agreements between the traits checked in the first column of Part 3 and the first column of Part 9. In Part 3 we have the opinion of the reagent on the most desirable traits to possess; in Part 9 he indicates which of these desirable traits he himself possesses. The number of agree- ments shows how desirable he considers his own traits. Results obtained with the primary groups are given below.

Group comparisons were made in the frequencies with which the different traits in Part 3 were checked. No important differences were found, the great majority checking the traits in the socially acceptable way. This is added proof of the objectivity of the decision made in the test. Traits Checked in Part 9. Similarly, group comparisons were made in the frequencies with which each trait in Part 9 was checked. While not to be accepted as a self-rating, it is often the case that under stress of time and under test conditions a person will give a truer estimate of himself than he would if he had time to reflect and rationalize. No startling differences were discovered, the great- est ones being the following: 8 of the primary sales group checked 28 MAX FREYD “slow,” whereas 17 of the primary mechanical group checked that trait; 18 salesmen and 12 industries students checked “quick’’; 9 salesmen and I industries student checked “cowardly” ; 17 salesmen and 27 industries students checked “brave.” Part 4. Speeded Writing. Scores were in terms of the number of letters written in Part 4. This is a measure of the subject’s greatest speed of writing. It is more or less a measure of coordination of impulses. The following results were obtained with the primary groups.

This part was rescored for reasons previously given. The revised scoring method is to obtain the ratio of the number of errors made to the number of possible errors by our scoring method, in the amount written. It leaves out of consid- eration the third sentence, but very few work on it. Results are as follows for the primary groups.

The difference is slight, with the salesmen ex- hibiting a greater tendency toward making errors. DIRECTED ASSOCIATION TEST This test was printed on two sheets, the first containing the di- rections and the second containing the body of the test. The first page is reproduced herewith. DIRECTED ASSOCIATION TEST EXAMPLE: Column I 1st Solution ‘and Solution NAIL NAIL NAIL hammer rust handle wood tree roots damp WATER WATER WATER THE SOCIALLY AND THE MECHANICALLY INCLINED 29 EXPLANATION: Note that in Column I there is no direct relationship between “NAIL” and “WATER.” You are to write words in the blank space in the column so that a continuous association is formed from “NAIL” to “WATER.” The example has been worked for you in two ways. Look at the first solution. Here “NAIL” suggests hammer,” “hammer” suggests “handle,” and so forth, “damp” finally suggesting “WATER.” Thus a continuous association is formed from “NAIL” to “WATER,” each word being suggested by the preceding one. The same thing is done in the second solution, but with only one word. On the following page you will find ten columns such as Column I. In each column you are to form a continuous association from the first to the last word. No stated number of words is required in each list, but make your lists as brief as possible. Work rapidly. Do not turn page until told to do so. The first and last words in the ten columns were as follows: sun-faith, day-blotter, potato-cement, sky-fever, inch-black, jour- ney-guilty, rifle-square, fun-question, sound-habit, copper-ignor- ant. -In giving this test the directions and examples on the first page were read aloud to the subjects and any questions answered. Then three minutes of continuous work were allowed on the test. The scores used in comparing the groups were: (1) the number of words per column, and (2) the number of columns completed. The character of the words written and the closeness of their associa- tion were ignored in scoring the test, as being impossible of simple and objective measurement. Group comparisons were not made by columns. This test was devised and used in the present study under the assumption that it measures ability in directed thinking. The per- son before whom the test is placed is required to direct his thought processes toward a definite end, and in order to receive a high score must keep his attention continually fixed on that end. It is easily imaginable that a person given to phantasy building, whose think- ing, in other words, is not directed toward serviceable ends, will lose his moorings at the first word and float away on a tide of words with no port in view. This type would be represented by those who on the average supply long lists of words and who also take plenty of time in completing the test. At the other extreme we should find the individual who is always present-minded and who 30 MAX FREYD directs his thinking toward definite objective ends. Such a person will get a high score in the test, 7.¢., he will write few words and finish most of the lists. The two types are represented in the two - solutions on the first page of the test. The number of words per column correlates +.28 with ratings on present-mindedness. The number of columns completed shows the extraordinary correlations of -++-.54 with ratings on self-asser- tion and +.64 with ratings on bearing. The following results were obtained with the primary groups and the Case School seniors in Mechanical Engineering. Numbers of words per column: Q, Q, Q, Industries seniors 1.60 2.25 3.05 Mech.

Eng. seniors 6.0 74 8.0 Succ. 1. i. salesmen 5.0 6.7 8.8 In each case the engineering students obtain the highest median score and the industries students the lowest. Since the salesmen occupy an intermediate position it is difficult to interpret the re- sults. If we ignore the engineering students, we note that the sales- men excel in speed of association, but that the industries students excel in directness and brevity of association. SERIES 12. KENT-ROSANOFF FREE ASSOCIATION TEST In its original form, as developed by Kent and Rosanoff (11) this test consisted of one hundred words which were presented orally to the subject one at a time. The subject responded in each instance with the first word which came to his mind, the response being recorded by the examiner. The test was in no sense a group test. The speed of response was at first recorded, but was later ignored owing to the magnitude of their undertaking. The originators of the test aimed to make a study of “certain disorders of the flow of utterance which appear to be dependent upon a derangement of the psychical processes commonly termed association of ideas” by “an application of the experimental meth- THE SOCIALLY AND THE MECHANICALLY INCLINED 31 od known as the association test” (11, p. 5). In order to have on record the responses of normal people so that these could be com- pared with the responses of the insane, the association list which they arranged was given to one thousand normal subjects. From an analysis of this material the authors are led to observe that “the one tendency which appears to be almost universal among normal persons is the tendency to give in response to any stimulus word one or another of a small group of common reactions” (I1,p.14). The tendency among the insane is to give unique responses, but it is conceivable that an original person of great ability may give uncommon responses. The possibilities of this test in the study of vocational differ- ences has been scarcely recognized. Since Kent and Rosanoff stan- dardized the test in 1910, little use has been made of it on normal adults. Wells and others have given us classifications of the types of responses, and Murphy has used it to some extent for the com- parison of people who are inclined toward literature with those who are inclined toward science. Most of those who have used the test were drawn to it by an interest in abnormal psychology. Its application to normal adults as a measure of various volitional and associational tendencies, rather than as a means of detecting insanity or complexes, has been passed over. The Bureau of Personnel Research has adapted this test for its use by printing the list and administering it as a group test, with- out any very apparent change in the function measured. No changes were made in the lists of words. The words are printed consecutively with blank spaces opposite them in which the re- agents write their responses. The directions and examples are read to the reagents by the examiner and any questions regarding them are answered. A starting signal is given, at which the subjects com- mence to_record their responses to the words in sequence, and at the expiration of four minutes a stopping signal is given. This form is far easier to administer than the individual test, and rein- troduces the factor of speed. The error of timing is reduced, since it can enter only into the first and last responses given by the sub- ject. We have only a measure of average time per word, instead of a separate measure for each word. Speed of writing is a factor 32 MAX FREYD which enters into the score on the number of responses given. The correlation of Speeded Writing (Part 4 of Test IX) with the number of responses in the Kent-Rosanoff Test is +-.37. Following are the directions for the test: Below is a list of 100 words. Write after each word the first word it sug- gests (the first word that comes to your mind). Do not write sentences. Do not stop to think. Work as quickly as you can. EXAMPLES: grass....green school.. .teacher For the purpose of this study, this test has been scored in thir- teen different ways, each of which is described below together with its results. ; Number of Responses. This score is simply the number of word responses given by the subject. General intelligence is probably the dominant factor in this performance. In this connection Wells says: . “Probably no one could seriously assert that increased emo- tional reaction is the sole cause of lengthened association time, though it need not be questioned that it is an important contrib- uting cause. The principal other factors are the failure to find a response that is intellectually satisfying, and a failure of predomi- . nance of any one among the associations presented” (23, p. 20). We might very well assert that these factors are inversely cor- related with intelligence. Speed of writing and general intelligence are the two tested functions which correlate most highly with the number of responses. The correlation coefficients are respectively +.37 and +.31. The interquartile ranges for the two primary groups are given below. The figures are practically identical for the two groups.

Q, Q QQ, Industries seniors 4 9 Bi Succ. 1. i. salesmen 3 8 1.4 There is a very slight tendency for the industries students to omit more responses. Coefficient of Commonality. The commonality score on a re- sponse is obtained by referring to the Kent-Rosanoff tables of re- sponses given by one thousand normal adults (11, p. 77). In these tables each response word is preceded by a number which repre- sents the number of individuals (out of the thousand) who gave that response to the particular stimulus word. For example, after the stimulus word “dark” we find appearing first the word “afraid,” with the figure 6 before it, indicating that six of the one thousand subjects gave the word “afraid” in response to the word “dark.” In scoring any person’s test paper, we give him a score of 6 if he writes the word “afraid” after the stimulus word “dark.” The score used in this study is the sum of the commonality scores of the first twenty-five responses given by the subject. This score is a criterion of the extent to which a person’s thoughts run in normal objective channels (24, p. 74). Responses with low commonality value are unique responses which usually refer to the stibject’s individual experience. We cannot, however, go so far as to say that a person who scores low has psychopathic tendencies, since unusual responses may be characteristic of a very original person. The genius and the imbecile may find a com- mon ground in their commonality score. Results obtained with the primary groups are given below. Om Q, 0; Industries seniors 1600 2100 3400 Succ. 1. i. salesmen 2300 3500 4400 The sales group shows a very significant superiority in this function. Responses with Commonality Value of Zero. This score is the number of responses entering into the preceding score whose com- 34 MAX FREYD monality value is zero, t.e., the number of words which were not found in the Kent-Rosanoff tables. Results obtained are as follows: Q, Q, Q, Industries seniors 1.6 21 4.5 Succ. 1. i. salesmen ny, 1.5 2.6 As a corollary of the results of the preceding scoring method we find the industries students obtaining higher scores in the num- ber of zero value responses.

Five additional scores were obtained, using the classification given by Wells (22, 24). Effort toward the classification of types of responses arose among psychiatrists. Some of the better known classifications are those of Wells, Murphy, Krapelin,Aschaffen- burg, Munsterberg, Claparéde, etc. Most of the classifications are detailed and more logical than psychological, and they offer great obstacles to practical use. Wells’ classification seems to possess more points of merit than the others, and was therefore chosen for use in this study. His classification is given on the following page. This extract is copied verbatim from “Association Tests’ (24, P. 77). 1, The egocentric reactions may be typified by— a. Predicate reactions. Cloud-ominous, flower-pretty, crooked-line, red-rose, scratch-cat, lion-roar, money-wish, invent-machine, weasel-stealth, beauty-rose, safe-quite, almost-grown, sing-well, never-decide, nicely-very (including the responses yes and no). b. Responses in the form of proper names. Citizen-New York, boy-Johnny, mountain-Kearsarge. c. Reactions interpreting the stimulus word as a proper name. Eagle-news- paper, park-square. d. Reaction involving the response of a pronoun. Hand-you, health-me. e. Interjections, failures of response or repetitions of the stimulus word. 2. The supraordinate category is confined strictly to the individual-genus order, defined in such examples as, priest-man, potato-vegetable, lily-flower, cow-animal. THE SOCIALLY AND THE MECHANICALLY INCLINED — 35 3. The contrast group is composed, of course, of reactions in which the re- sponse means the opposite of the stimulus and is made up of such associations as, good-bad, trouble-pleasure, scatter-gather, fertile-sterile, and the like. 4. The miscellaneous category is composed essentially of the remaining reactions of the “inner” type. It includes about 45 percent of all associations. 5. The speech-habit group is composed of associations by familiar phrase (stand-pat) ‘word compounding (play-ground) simple sound associations (tease-sneeze) and syntactic changes (high-height). The purpose of a classification of this sort is to gain an insight into some of the mental processes. The only modification made in the use of this classification was to substitute the word “subjective” for “egocentric” in naming the first category, in order to avoid the connotations of the latter word. The responses falling into this group are not egocentric in the sense that they disclose a self-centered personality, but in the sense that they are not objective or universal. The scores for each of the five categories consist of the number of responses belonging to that category out of the first twenty- five words in the list; not necessarily the first twenty-five responses made by the subject, since omissions of response are classified as subjective responses. Some difficulty was encountered in using this classification since a great many words could fit with equal justification into several of the classes. Subjective Responses. The following results were obtained with the primary groups. Oo; (Oia Oy, Industries seniors 5.5 11.0 16.3 Succ. |. i. salesmen 3.0 8.0 12.0 In view of the fact that subjective responses have low common- ality value, we should expect these results. Supraordinate Responses. Very few responses of this type oc- curred. Twenty-one of the industries students and twenty-six of the salesmen made no responses of this type. Contrast Responses. Since this has proved to be the most im- portant single score yielded by the test, it deserves special attention. It correlates -++.92 and -++.98 with the coefficient of commonality, and since it is a much easier score to obtain than the commonality score (a matter of several seconds compared with over a minute) 36 MAX FREYD it may be very easily substituted for that score. It also correlates —.9o and —.86 with the number of subjective items, another im- portant score which is difficult to obtain. It yields fairly high cor- relations with most of the other scores obtained from this test, and consequently is the most significant and representative score yielded by the test. All of the groups were scored on the number of contrast re- sponses. Results are given below and in Fig. 7. Industries Seniors STAB ee West. N.S. Seniors ——— Harr. RE. Salesmen Sra RS LD Cleve. Disc.

The following are less significant results: Mechanically inclined people excel in Enlargement of writing under distraction (Part 5, Test IX). Ratio of objective to subjective speed of decision (Part 9, ratio, Test IX) . Agreements between checks in Parts 3 and 9. Speeded writing (Part 4, Test IX) Salesmen excel in Number of disguises attempted (Part 6, letters, Test IX) Speech-habit responses in the Kent-Rosanoff test. Contrast responses in the Kent-Rosanoff test. SUPPLEMENTARY NOTE The following table gives a more accurate estimate of the tested differences than is afforded by comparisons of interquartile ranges. The figures show how significant are the differences in means between the Mechanical Group and the Miscellaneous Sales- men and the Life Insurance Salesmen combined, in those tests in which results on these large groups are available. In Part 3 of Test IX, for instance, the group referred to as the Mechanical Group is compared with the Miscellaneous Salesmen and the Life Insur- ance Salesmen combined. Differences between the primary groups have not been treated in this manner since the procedure has no value with small groups.

The questionnaire method is objective and has the ad- vantages that no timing is necessary and groups do not have to be assembled for purposes of administering the papers. For the same reasons, however, a certain caution must be observed. If the pur- pose of the questionnaire is obvious there is nothing to prevent the subject from filling it out in the way which he thinks will best serve his interests. In order to make the answers more valuable, the purpose of the questionnaire must not be too apparent. If under these circumstances the subject guesses at the purpose and fills out the questionnaire falsely, he runs no greater chance of hitting upon the “right” answers than he would in a test. In this study a series of five detailed questionnaires was submit- ted to the two primary groups and to the Case School seniors. Group comparisons were made in answers given. By this means it was intended to study differences in personality as expressed in in- terests and attitudes, and to determine the importance of personal history as a cause for any differences in personality disclosed. No statistical evaluation of the differences was made, owing to the immense amount of computation involved. In the presenta- tion of the results, the original figures are given in most instances. DESCRIPTION OF QUESTIONNAIRES The subject matter of the five questionnaires is roughly the fol- lowing: Questionnaire 1, early personal history; Questionnaire 2, vocational interests; Questionnaire 3, avocational interests; Ques- tionnaire 4, likes and dislikes; Questionnaire 5, beliefs. The 40 MAX. FREYD groundwork of the lists was a series of questions submitted to C. S. Yoakum by students enrolled in a seminar in personnel re- search in 1919, at Carnegie Institute of Technology. These ques- ~ tions were intended to reveal a cross-section of an individual’s personal history and interests at several important stages of his development. It is due to the incentive furnished by Yoakum that the series of questions was compiled and that modified forms were used in this study. In addition to this source, items were drawn from the published material of the following men: Allport, Baade, Lipman, and Stern, Cimbal, Healy, Hoch and Amsden, Meyer, Moore, Pressey, Sommer, Stern, Wells, and Woodworth. A num- ber of forms in use at various institutions were also consulted. Items for the questionnaire on beliefs were contributed by M. A. Bills and L. D. Anderson, of the staff of the Bureau of Personnel Research. Some use was made of the lists given by Kemble, Nathan and Mencken, and Sumner. Questionnaire 1. Early Personal History. The personality of an individual is the resultant partly of heredity and partly of en- vironment. The latter commences its modifying influence directly after birth, and during childhood so molds the individual that the impressions of this period have more influence in shaping his per- sonality than those of any later period. By finding out what these impressions were, we can better understand the personality of the adult. In our case we can determine to what extent the individuals in the same vocational group were subjected to the same influence ~ in childhood. The most thorough attempts to determine the effect of environ- ment in shaping the adult personality have come from psychi- atrists. Before attempting to cure his patient the psychiatrist makes it a point to have before him all the material he can assemble on the past history of the patient. He can then trace the causes of the malady and apply such curative methods as-the case demands. That personal history is an important factor in vocational choice and success has been proved by Andrews (1), Goldsmith (8), and Ream (17). These workers have found that certain facts yielded by questions ordinarily included in application blanks have such great vocational differentiating value that workers may with fair THE SOCIALLY AND THE MECHANICALLY INCLINED 41 success be chosen merely on the basis of their answers to these questions. Their results have been carried over into this study on a larger scale. Questionnaire I consists of seventy questions covering paren- tage, and early home and social environment, etc., up to the ap- proximate age of twelve. Questionnaire 2, Vocational Interests. Questionnaire 3, Avo- cational Interests. Questionnaire 4, Likes and Dislikes. Questionnaire 2 covers items of vocational interest. The third page is a modification and enlargement of a form used by Moore (13) for determining occupational interests. The 72 occupations are listed in alphabetical order, but they are readily classified into general groups, such as scientific occupations, literary occupations, selling, indoor work, outdoor work, executive work, etc. Questionnaire 3 covers such items as hobbies, literary interests, diversions, athletic interests, social tendencies, religious tenden- cies, etc. Questionnaire 4 contains 129 items toward which the subject expresses his attitude, and which fall into three general groups: first, a series of physical attributes of people, up to item 26; sec- ond, a series of mental attributes of people, items 27 to 76; and third, a series of miscellaneous items, 77 to the end. In addition to the detailed tabulation of the answers given by groups of indi- viduals, this questionnaire offers information on personality in the total number of each kind of symbol checked in response to the first 76 items. Correlations with ratings (Chapter V) show that the person who tends to check a great many “?” after the first 76 items tends also to be rated as flexible and adaptable (r == +.48). The person who checks a great many L’s and L!’s after these items tends to be rated as submissive (r == +.43), self-conscious (r = +.43), and unadaptable (r == +.31). Group comparisons on the basis of the number of such symbols checked reveal no dif- ferences. | An individual may go into an occupation not only because of certain factors in his personal history or because of an interest in that occupation, but also for the reason that he has a number of concomitant interests which are gratified by the type of work he 42 MAX FREYD has elected to enter upon. In addition to sales ability or abilities, which may be difficult to fathom, successful salesmanship is due to communities of interests all of which find an outlet in sales tasks; such interests, for example, as in talking to and meeting people, in variety in daily work, in walking around rather than sitting at a bench all day, and so on. It has been shown that records of such interests are valuable supplements to tests for the selection of salesmen. It does not matter much for present purposes how we define interests. In behavioristic terms, interest in an object may be de- fined as a tendency to make positive reactions toward that object. Introspection would add the affective element, or “likes.’’ We are not concerned here with interests that are mere reflexes, such as the interest in a bright light in the periphery of vision. Rather we are concerned with those which are developed in a social environ- ment and are based on either heredity or social habit. Very little scientific study of interests has been made up to the present. The outstanding researches are those which Thorndike (19) has carried out on interests in school studies. The methods used were such as to make the results of limited significance. They point to the conclusion that courses tend to maintain their relative degree of interest throughout school or collegiate life; that a high correlation exists between a person’s interest in a school subject and his ability in that subject as judged by himself; and that a significant, but somewhat lower, correlation exists between inter- est in a subject and ability in it as measured by school grades. The conclusions give weight to any arguments for the use of interests as auxiliaries to measures of abilities. The analysis of interests has played a prominent part in two major studies produced by members of the staff of the Bureau of Personnel Research. Moore (13) used an interest questionnaire in differentiating among a group of graduate engineers those who inclined toward design engineering and those who inclined toward sales engineering. The section of his interest questionnaire which proved to be the most reliable for the differentiation of the two groups was a record of occupational preferences. A scoring method for this blank was determined empirically; that is, if a THE SOCIALLY AND, THE MECHANICALLY INCLINED 43 larger proportion of the sales engineers than the design engineers liked a certain occupation, this reaction to the occupation was assigned a score favorable to sales engineering. The total score for any person indicated whether his inclinations were in the di- rection of design engineering or sales engineering. No attempt was made to determine the relative significance of the items en- tering into the total score, all such items being weighted one. By means of the total score on choice of occupations, 82 per cent of the men were placed properly, in other words, with the most favor- able critical score, there was an overlapping of only 18 per cent. Ream (17) used interest blanks very much like Questionnaires 2 and 4 of the present series, in his study of methods of selecting successful life insurance salesmen. In his study a refinement of statistical procedure was introduced, namely, where the propor- tions of successful and unsuccessful salesmen who liked or dis- liked an item differed considerably, the ratio of the difference in proportion to its standard error was calculated. All items in which this ratio was one or more entered into the total score on the in- terest blanks. All items were weighted one. Distributions of total scores on the interest blanks showed that by their means approxi- mately 80 per cent of the men were placed correctly. Any attitude which has a strong emotional accompaniment may be called a “complex.’’ Thus Hart (Psychology of Insanity) speaks of the photography complex. Pressey has tried to measure the complexes of an individual by the questionnaire method (15). His contribution presents two aspects of interest: (1) the blank is made extremely concise and compact by printing lists of words with directions for expressing one’s attitude toward them at the top of the page, each word thus representing what would ordinari- ly be a complete question; (2) a method is given for obtaining a total score. Pressey selected for his total score ten items crossed out in greater proportion by successes in school and ten others crossed out in greater proportion by failures. By subtracting each of the latter from the former (checked by any student) he ob- tained a total score which differentiated successes from failures. The overlapping of the distributions for the two groups, using the most favorable critical score, was only Io per cent (11/106). 44 MAX FREYD Questionnaire 4 serves a somewhat similar purpose. Complexes are here disclosed by checking L! or D! These checks are due to | emotionally toned incidents in the previous experience of the re-» agent by which the object of the complex acquired a gil or unfavorable halo. Questionnaire 5. Beliefs. The final questionnaire consists of a number of questions on which people tend to disagree. The answers are therefore measures of attitudes, perhaps emotionally toned, and in a limited sense serve to gauge the subject’s informa- tion. That attitudes expressed in answers to such questions are of vocational importance, is shown by one study at least, that of Leuba (12, p. 255) on the belief in God and immortality. He com- pared leaders and lesser men in the physical and biological sciences in the proportion of their numbers believing in God and immor- tality. The proportions are as follows: PER CENT BELIEVING IN GOD IM MORT. Physical sciences Leaders 34.8 40.0 Lesser men 49.7 ra Biol. sciences Leaders 16.9 25.4 Lesser men 39.1 45.1 These figures have no direct bearing on the present study except as they show the possibility of obtaining important. group differ- ences in reactions to moot questions.

Eighty per cent of the fathers of the salesmen were born in this country; 60 per cent of the fathers of the industries students ; and 53 per cent of the fathers of the engineering students. 6. The per cents of fathers of American or British nationality among the three groups to whom the questionnaire was given are: primary sales group, 73 per cent; primary mechanical group, 56 per cent; and Case School seniors, 46 per cent. American nationali- ty: 23, 13, and II per cent, respectively. 7. The per cents of mothers born in this country are: salesmen, 83 per cent; industries seniors, 43 per cent; and engineering stu- dents, 72 per cent. 8. The per cents of mothers of American or British nationality are as follows: salesmen, 67 per cent; industries students, 43 per cent; and engineering students, 39 per cent.

The follow- ing are mentioned once by the engineering students: Caesar, Han- nibal, J. P. Jones, Grant, King Richard of England, Edison, Alex- ander, and Aeneas. Brill (2) calls the answer to this question the person’s empathic index. The answer indicates the person’s trend of adjustment to the world. A certain personage is admired because of a wish to emulate his mode of reaction to the world. He expresses in his life the conscious and unconscious strivings of those who consider him their ideal. Questionnaire 4. Likes and Dislikes The most important group differences found are the following: the salesmen show a greater proportionate liking for fat men, con- ventions, “Life,” and interviews; the industries students show a greater proportionate liking for very polite people and ‘““The New Republic.” The per cents of the salesmen, industries students, and mechanical engineering students, respectively, checking L! or L after each of these items are: fat men: 55, 17, and 37; very polite people: 47, 90, and 40; conventions: 73, 53, and 49; “Life”: 97, 77, and 93; “The New Republic” : 33, 77, and 14; interviews: 77, 33, and 51.

(1) A greater proportion of the sales group than the other two groups are of native or British Protestant stock. Their parents were better educated and wealthier than those of the industries students. They were thus afforded the advantage of a better social adaptation in this country, which may have been a factor in their choice of salesmanship as a vocation. ¢ 60 MAX FREYD (2) The industries students were apparently subjected to great- er maternal influence in childhood than the salesmen. We find that more industries students than salesmen “‘took after” their mothers; more resembled the mother’s side of their ancestry; more of them liked their mothers in preference to their fathers; more of them state that their mothers exercised the most influence on their lives; and more of them state that their mothers were dominant in the family. A possible explanation is that the predominant influence of the mother may have caused the industries students to become less successfully adapted toward other individuals. They may have clung to their mothers’ apron-strings for too long a period in child- hood. On the other hand, the attachment to the mother may have been symptomatic of more fundamental factors influencing per- sonality. We should expect to find among the industries students compensatory reactions for the weaknesses expressed in their atti- tudes toward their mothers, in that they may have taken an ag- gressive attitude toward their social environment instead of a tact- ful one. - (3) The industries students were evidently not wholly satisfied with their early environment. A greater proportion of them than of the salesmen would desire a change in their home and other early environmental conditions if they were to live their lives over again. More of them would prefer a wealthier environment, more refined companions, and more cheerful conditions. They were treated slightly worse than their brothers and sisters. Their early lack of tactful social adjustment is demonstrated by the fact that — they engaged in more-fistfights as children than the salesmen. Questionnaire 2. (4) In their choice of occupations the salesmen tend to choose the characteristically social occupations and the industries students the mechanical ones. Occupations preferred in greater proportion by the salesmen are: actor, automobile salesman, editor, foreign correspondent, lawyer, magazine writer, newspaper reporter, nov- elist, philanthropist, politician, preacher, real estate salesman, specialty salesman, and surgeon. The industries students are more inclined toward the following occupations: astronomer, auto fe- THE SOCIALLY AND THE*-MECHANICALLY INCLINED 61 pairman, bank teller, baseball player, carpenter, draftsman, ex- plorer, factory manager, hotelkeeper or manager, labor arbitrator, locomotive engineer, machinist, mechanical engineer, musician, office manager, promoter, ship officer, shop foreman, stock broker, toolmaker, and watchmaker. It is an interesting fact that salesmen prefer literary occupations, while the industries students prefer financial occupations. Questionnaire 3. (5) In their attitudes toward school subjects the industries students show the expected liking for shop work, mechanical draw- ing, and manual training. The salesmen prefer economics, sociolo- gy, civics, and public speaking. (6) The salesmen show their social proclivities in that they learned to dance earlier in life and maintain a greater social cor- respondence than the industries students. They probably make themselves less objectionable by not trying to convert people to their religious point of view, although in this respect the indus- tries students show a more marked sales tendency than the sales- men themselves. (7) Salesmen are more credulous in that they tend toward a greater belief in pseudosciences. (8) Among the salesmen the ideal personage is more often Roosevelt and less often Lincoln. Roosevelt expresses a more normal vigorous empathic index. Lincoln expresses an ethical and conscientious attitude toward life. Questionnaire 4. (9) Salesmen show a greater preference for fat men, conven- tions, interviews, and “Life.” Industries students show a greater preference for very polite people and “The New Republic.” The connotations of a preference for good-natured fat men and for “Life” are obvious. Salesmen probably show less liking for very polite people because such people are less free in their social ex- pressions and are more difficult prospects to handle. Questionnaire 5. (10) In their beliefs salesmen show greater credulity and con- 62 MAX FREYD formity with popular opinion than the industries students. The lat- ter display to a great extent the laboring man’s attitude. In most respects the mechanical engineering students occupy an intermediate position, although their leanings are in the direction of the industries students rather than the salesmen. We may con- clude that engineering draws men with slightly greater social pro- clivities than a course such as the one which the industries students follow. CHAPTER TV GROUP COMPARISONS BASED ON RATINGS Group comparisons based on ratings were made in order to deal with a number of traits, (some of which presumably were also measured by the tests and questionnaires), which seemed to be re- lated to the personalities studied. Ratings were obtained on only three groups: the two primary groups and the Case School seniors in mechanical engineering. The data include self-ratings by the members of these groups, plus ratings on them by acquaintances. THE METHOD All the ratings reported here were made on the same scale, a graphic rating scale which afforded ratings on twenty traits. The graphic rating scale is a form in which the rating is indicated by a check along a straight line, under which are printed descriptive phrases indicative of varying degrees of the trait, from one ex- treme to the other. The advantages of this form of scale are set forth in another place by the writer (6). The directions for the present scale and an illustrative item are given below.

In the original it is 65% inches long. 64 MAX FREYD The “good” ends of the scales were alternated in order to coun- teract a motor tendency to check at one edge of the blank. The time required for making the twenty ratings was approximately ten minutes. To score the ratings a stencil was used, one of whose edges was marked off for a distance equal to the length of the graphic rating line. This space was divided off into twenty spaces of equal length, consecutively numbered from left to right. The stencil was placed beneath the line on which the rating was made, so that this line coincided with the marked-off space on the stencil. The score was the number of the space over which the check was made. If the check was made over a division line between two spaces, the score to the right was assigned to the rating. An X-shaped check was scored at the intersection of the two lines, and a V-shaped check at the point of the V. If more than one check was made on the same scale for the same person, indicating doubt on the part of the rater, the average of the ratings was taken. Since the same stencil was used for all the scales, all scores read from left to right. No total score was obtained. The following additional directions were used in obtaining self- ratings from the industries students. Similar directions were used in obtaining self-ratings from the other two groups. “Tt is requested of each senior in Industries that he fill out the enclosed blank and mail it to this office. Our purpose in asking for this information is to provide a check on the tests which were re- cently given, by comparing ratings on character traits with the © test scores. “The rating scale which is enclosed was not intended for self- rating, but we wish you to use it in that way. Let the ratings which you make represent your judgments on your own traits. That is, you are to judge yourself, taking the point of view of an impartial observer. If you care to, you may add marginal comments to make your ratings clearer or to supplement them. “We wish to make it absolutely clear to you that these ratings will be kept confidential. None of the records will go out of this office. They will not be made known to the employment office or to any of your instructors. Do not sign your name to the blanks.” The scales were numbered so that they could be identified THE SOCIALLY AND THE MECHANICALLY INCLINED _ 65 when returned. The industries students returned their ratings by mail, but the other two groups rated themselves in the classroom, with instructions similar to the above. In order to get ratings by acquaintances on these men, as checks on their self-ratings, each member of the three groups gave the names of five men to whom the scale could be sent. To each of these references were sent a copy of the scale and a letter requesting ratings on the student. Out of approximately 400 rating scales sent out, 80 per cent were returned completely filled out. Except in rare instances, no two men were rated by the same judge; that is, with rare exceptions, no two men gave the same reference. All self-ratings and ratings by acquaintances were made anonymously. Distribution tables of self-ratings and ratings of others were drawn up and the interquartile ranges were calculated. The ratings of others include all ratings, and since some men were rated by five references and others by merely one, the ratings of others do not completely represent the groups. All of the engineering stu- dents were rated by three or more people, but about one-fifth of the other two groups were not rated at all by others. RESULTS The interquartile ranges of the self-ratings and the ratings of others for the three groups are shown graphically in Fig. 8. In order to make the results more apparent and to bring out features which would not otherwise be noted, the rating scale instead of the scale of scores is placed below the lines. There are several outstanding facts about these ratings. (1) The general tendency is for raters to make checks directly above descriptive phrases. This is to some extent an error in the use of the scale which should be overcome with practice, and to some extent a weakness in the scale itself. (2) Several of the scales, especially those for Traits 1 and 2, are shown by the interquartile ranges to be defective. The central phrase in every scale should be a neutral one, or should express the most common condition of the trait found in the population at large. The defects of these two scales are made evident by the displacement of the distributions, due to the fact that the central 66 MAX FREYD phrases are more nearly allied in meaning to the unfavorable than the favorable ones. (3) Several other scales,—those for Traits 16 and 17, for in- stance,—are defective because, as indicated by the narrow range of ratings, the intermediate phrases are more nearly like the ex- tremes than they are like the central phrase. Raters therefore tended to avoid them. (4) The general trend is for acquaintances to rate the men higher or more favorably than they would rate themselves. This is true for Traits 1, 2, 3, 4,6, 7,9, 11, 12,14, 19, and 20. Whether this is due to self-depreciation on the part of the subjects of the study or to flattery on the part of their acquaintances, cannot be deter- mined. As we are not in possession of the facts, the ratings must be accepted at face value. (5) The differences between the groups in self-ratings and in the ratings of others are in most cases slight, but they gain sig- nificance from the fact that in almost every case where a difference appears in self-ratings it is corroborated by the ratings of others, and from the fact that the differences are consistent. The direc- tions of the differences between the successful life insurance sales- men and the industries seniors are shown below, based on self- ratings. 1. Salesmen are more wide-awake 2. Salesmen are more good-natured 3. Salesmen are neater 4. Salesmen are more excitable 7. Salesmen are less self-conscious g.

The above differences are reversed by the ratings of others in Traits 9, 11, and 20. Every one of the differences but these three is corroborated by the ratings of others on the men. In addition, the differences are borne out by the self-ratings of the seniors in mechanical engineering.

SUMMARY Although the rated differences are not so great as to withstand detailed statistical examination, they gain significance from the fact that they are psychologically consistent, that self-ratings and the ratings of others corroborate each other in most of the traits, and that the differences between the primary groups in self-ratings are borne out by the self-ratings of engineering seniors. The most significant differences between the primary groups are in Traits 4, 10, 14, and 15. They lead to the conclusion that salesmen are more excitable, more self-confident, and more open- hearted than industries seniors, and make friends more quickly. There is a less significant tendency for salesmen to be more wide- awake, good-natured, adaptable, and talkative, neater, and less self-conscious than industries seniors. GHAP DER W INTERCORRELATIONS OF TESTS AND RATINGS Though not an application of Spearman’s method of proving the existence of a general common factor, the method to be de- scribed is related to it in such an intimate way that it will be neces- sary to give first a brief summary of the development of Spear- man’s two factor theory (3, 10, 18). THE THEORY OF GENERAL ABILITY Spearman first put forth his theory of general ability in 1904 (18). He found that after intercorrelating a number of measure- ments of mental abilities, the correlation coefficients could easily be arranged in a hierarchical order, 7.e., so that on the whole each coefficient was greater than any to the right of it in the same row or below it in the same column. “This fact of ‘hierarchical’ order which he had thus discovered was taken by Professor Spearman to indicate the presence of some common fundamental function which saturates in different degrees the different activities, and is the sole cause of correlation between them except in the case of very similar activities. “Tt can easily be shown that if all the correlations are due solely to one common or general factor, then the correlation coefficients - will be in perfect hierarchical order. “Since clearly perfect hierarchical order cannot be expected in any experimental research, it becomes important to. know what deviation from prefection can be allowed without giving up the idea of a general factor: or on the other hand, what approach to perfection can be attained without the presence of a general fac- tor.” (3, pp. 165-166) Spearman devised a formula for correcting for observational errors which, applied to his correlation coefficients, enabled him to arrange them in perfect hierarchical order. The suppositions underlying this formula have been called in serious question by Thomson (3). THE SOCIALLY AND THE MECHANICALLY INCLINED 75 Researches between 1904 and 1912 differed in the degree of hierarchical order obtained. In 1912 Hart and Spearman pro- posed a criterion for the existence of a hierarchical order, whose underlying idea was that the correlation of adjacent columns of correlation coefficients, if perfect hierarchical order existed, would equal unity, and that its value is therefore a measure of the com- pleteness of the hierarchical order. We need not concern ourselves in detail with the criticisms lev- eled against the theory by Thomson, aside from noting that he produced hierarchical order through a random overlapping of group factors in the absence of a general factor, and that he at- tacks the validity of Spearman’s correctional formulae. He re- places Spearman’s two-factor theory (a factor specific to the ability, and general common factor: intelligence) by a sampling theory of ability, preferring “to think of a number of factors at play in the carrying out of any activity such as a mental test, these factors being a sample of all those which the individual has at his command.” (3, p. 188) MeETHOD EMPLOYED IN THIS STUDY A possibility of the table of intercorrelations which seems to have been overlooked by these writers is to study through them the differences existing between groups as regards the interrelation- ship of their traits. It cannot be said that differences greater than those to be expected by chance between two tables of intercorrela- tions of the same measurements obtained from two different groups of subjects would account for two general factors, but it seems possible that these differences would at least show what specific factors were common to the members of a group. Sup- pose that in Group A we find the three highest intercorrelating measurements to be 1, 2, and 3; and in Group B the three measure- ments showing the highest intercorrelations to be 8, 9, and 10; all these intercorrelations to be over +-.90. Even though these dif- ferences were too great to be ascribed to errors of observation, they could not be attributed to the degree to which the variables were saturated with a general common factor. They must be due to the constitution of the two groups, and these varying factors in 76 MAX FREYD the two groups can only be described in terms of the intercorre- lating traits themselves. Thus, for unknown reasons, Traits I, 2, and 3 always accompany each other in equal degrees in the mem- bers of Group A, forming a constellation of traits for that group; similarly, Traits 8, 9, and 10 form a constellation for Group B. A second possibility is to make tables of the intercorrelations of traits obtained from merging the two groups, and then having found what traits form constellations, all men considered, to de- termine to what degree the groups differ in the extent of the con- stellation which they possess. If, for instance, we should find that Traits 5, 6, and 7 formed a constellation with the data from all the groups combined, it would be interesting to note if the groups differed in their possession of these traits, the latter accom- panying each other in a large amount in one group and in a small amount in the other group. This could be determined by comparing distribution tables of the amounts of each trait possessed by the two groups. I have used both of these procedures with the groups on which the figures were available: the two primary groups and the Case School seniors in mechanical engineering. The correlations were all obtained by the Spearman fourfold table method, which although merely an approximation and subject to considerable error, is perhaps as reliable as any, considering the number of persons in the groups. The following tables of intercorrelations of measurements were obtained : 1. Intercorrelations of self-ratings for the sales primary group. 2. Intercorrelations of self-ratings for the mechanical primary group. Trait 17 was omitted, as the form of distribution of this trait did not permit of the calculation of correlations. 3. Intercorrelations of self-ratings for the Case School seniors in mechanical engineering. Trait 17 was omitted. 4. Intercorrelations of average ratings for 84 cases. These 84 cases were members of the three preceding groups who had been rated by two or more acquaintances. The average rating for any man in any trait was a figure obtained by first averaging the opin- ion of his acquaintances on this trait, and then averaging this com- bined opinion with the man’s self-rating on that trait, giving his THE SOCIALLY AND THE MECHANICALLY INCLINED rip self-rating and the combined judgment of his acquaintances equal weight. 5. Intercorrelations of all test scores for the sales primary group. 6. Intercorrelations of all test scores for the mechanical pri- mary group. 7. Intercorrelations of all test scores for the 84 men mentioned in connection with the fourth table above. 8. Correlations of all test scores with the average ratings of these 84 men. These tables of intercorrelations are not reproduced here. In calculating the correlation coefficients where ratings were concerned, one end of the range of actual ratings was arbitrarily accepted as the better end. In many of the scales either end repre- sents an extreme which is undesirable, but checks were rarely made over these extremes. Within the limits of distributions of checks, the good end is easily distinguished. In correlating ratings, the rating at the ‘good’ end of the scale was called high, and the trait was called by the ‘good’ name. In doing this numerical scores were disregarded as expressions of the amount of the trait, and were used merely to obtain medians. The effect is as if the good end of the scales were always to the right instead of being alter- nated, and as if a rating to the right of the median were consid- ered high and to the left low, and the name of the trait were always the right extreme. In obtaining intercorrelations where tests were concerned, a high score represented a high standing. It is unfortunate that writers on the general factor theory give us no method for the closest approximation to hierarchical order where that order is not immediately and obviously made. Brown and Thomson mention in passing two methods, or rather two variations of the same method (3, p. 177, footnote, and p. 185). The method rests on the probability that the ability represented in the upper row and left-hand column in a hierarchical order approaching perfection will have a larger total correlation than any other ability represented in the table, and that the total cor- relations of the other abilities will be in the same order as their 78 MAX FREYD position in the table. A brief method of ranging the measured abilities in hierarchical order is, therefore, to range them in the order of the sums of their correlations with the other abilities (their total correlation). In doing this we are immediately confronted with the question: shall we take the algebraical totals of the correlation coefficients or shall we disregard the signs in computing the sums? In the one example given by Brown and Thomson all the coefficients are positive. If, however, the hierarchy were arranged with only high positive coefficients in the upper left-hand corner, we should ex- pect a number of high negative correlation coefficients in the lower right-hand corner. The last situation is practically impossible, since a group of traits cannot show very high negative intercorrelations. It is possible for a group of traits to show a great many high posi- tive intercorrelations and a few negative ones. Thus, Traits 1, 2, and 3, may intercorrelate very highly (averaging ++.90, for ex- ample), and Trait 4 may correlate negatively with each of these traits. The constellation of traits would then consist of Traits 1, 2, 3, and 4, the first three accompanying each other to the same degree and being accompanied by inverse amounts of Trait 4. In obtaining total correlations, therefore, the signs of the cor- relation coefficients have been ignored. RESULTS As the tables of intercorrelations will not be reproduced here, the reader will have to keep in mind what they aim to present. Each of the eight tables mentioned contains all the correlation coefficients resulting when each of the variables (ratings or tests) is correlated with each of the other variables with which the par- ticular table is concerned. In addition, for each variable in each table, the total correlation is given, a figure which represents the sum of the correlation coefficients of that variable with each of the other variables in the table, the signs of the coefficients being neglected. As a preliminary step, the total coefficients of the variables (self- ratings) in the first table were correlated with those in the second table and with those in the third table, and those in the second table THE SOCIALLY AND THE MECHANICALLY INCLINED 79. with those in the third table. These correlation coefficients were calculated by the rank order method. Thus in the first table, Trait 2 ranked first with a total correlation of 7.37, in the second table Trait 2 ranked fourteenth with a total correlation of 4.77, and in the third table Trait 2 ranked thirteenth with a total correlation of 5.05. The correlation of the values of the total correlation coef- ficients in the first and second tables is —.21, first and third —.13, and second and third +.27. In other words, the figures for the sales group correlate negatively with those for the two groups of mechanics students, whereas the latter correlate positively with each other. This indicates that the two groups of mechanics stu- dents will resemble each other as regards their constellations of traits more closely than either will resemble the sales group. Out of each of the first three tables of intercorrelations the five traits with the largest total correlations were chosen. The inter- correlations of these traits are given below. ‘Sales primary group (data from first table) : TRAIT 2 II 19 15 6 2 +.64 -.51 —A5 73 II +.71 —.66 +.56 19 —.71 +.31 15 —.56 Mechanical primary group (data from second table) : TRAIT. 5 8 18 I 4 9 8 —.51 +.51 —.59 .00 18 +.66 +16 +.977 I +.51 +.51 4 +.68 Case School seniors (data from third table) : TRAIT 18 4 5 13 16 18 gl aero? tooy +.59 4 +.64 37 +.40 5 + .66 +.28 13 +.56 In each of the above cases the traits are arranged in the order of their total correlations. In the first table, the five traits showing the highest total correlations are in order, 2, I1, 19, 15, and 6. In the sales group positive amounts of Traits 2, 11, 19, and 6, 80 MAX FREYD accompany negative amounts of Trait 15. The constellation for this group is therefore the following: 2. Good-nature 11. Even temper 19. Artistic taste 6. Accuracy in work 15. Close-heartedness It should not be assumed that these phrases describe the group. They represent extremes of traits which accompany each other in these individuals. It is just as logical to give the names of the op- posite traits to the constellation. By reference to Fig. 8 we find that the salesmen are more good-natured than the industries. students, whereas the latter are more close-hearted. No important differ- . ences appear with respect to artistic taste, accuracy in work and even temper. The discriminating value of this constellation is therefore very slight. oni For the industries seniors Traits 18, 1, 4, and 9 inter-correlate positively. Trait 8 shows no consistent relationship to the other traits and is consequently omitted in naming the constellation: 18. Talkativeness 1. Present-mindedness 4. Cool-headedness 9. Good bearing Referring to Fig. 8, salesmen excel in talkativeness and present- mindedness, whereas the industries seniors excel in the other two traits. | The constellation for the seniors in mechanical engineering is: 18.

Sociability with the other sex No valuable conclusions as to group differences in constellations of traits can be drawn from these results. Turning to the intercorrelations of average ratings (fourth table), we find the intercorrelations of the five traits with the largest total correlations to be as follows: THE SOCIALLY AND THE MECHANICALLY INCLINED 81 TRAITS . 18 13 I 2 20 18 +.37 -+-.10 +.16 +.37 13 +.45 +.29 +.66 I +.43 +.51 2 +.16 The constellation, though not very coherent, consists of the fol- lowing traits: 18. Talkativeness 13. Flexibility 1. Present-mindedness 2. Good-nature 20. Quickness in work In every one of these traits the sales group excels the industries students. Here we have the basis for a group differentiation as regards a constellation of traits. These traits form a constellation, perhaps in the general population, and also individually differen- tiate the two groups. The terms in the above list are then the best oties to apply to the general traits of the groups in differentiating them. Similar comparisons with regard to test scores are less reliable since we have included several measures from the Kent-Rosanoff Test which are very closely related. The five test scores with the largest total correlations for the sales group (fifth table) are all in the Kent-Rosanoff Test, being Adjective and Adverb Responses, Noun Responses, Speech-Habit Responses, Contrast Responses, and Responses with a Common- ality Value of 1-5. The comparison of these results with those of the sixth table produced entirely negative results. No differentiat- ing constellations were discovered. The intercorrelations of test scores for three groups combined (seventh table) yield more favorable results. The intercorrelations of the five tests with the largest total correlation are given below. All are in the Will-Temperament Test. TEST PT.9 PTS.IANDIO PT.9Q,F. POCO ee rr.

An ideal arrangement would exist here if one group of subjects excelled the other in all of these tests except Part 9, ratio, and if every test in the five correlated highly with the constellation of rated traits on the preceding page. We should then have found a differentiating constellation of rated traits and adequate measures cf them for use on other groups of subjects. The sales primary group excels the industries group in Part 9, Part 6, letters, and Part 4, ratio. The industries students excel in Part 9, ratio, and very slightly in Parts 1 and 10. This seems to offer a possibility that the ideal arrangement would be obtained. The correlations of each of the five tests with each of the five ratings are given below (from eighth table).

SUMMARY The results of this attempt to find differentiating constellations of traits are for the most part negative. This may be due partially to the unreliability of the correlation coefficients, and partly to the nature of the method for selecting the traits entering into the constellation. The intercorrelations of average ratings showed the most posi- tive results. With the data from the three groups combined, the following traits formed a constellation: 18. Talkativeness 13. Flexibility or adaptability 1. Present-mindedness 2. Good-nature 20. Quickness in work In all of these traits the salesmen rate higher than the industries THE SOCIALLY AND THE MECHANICALLY INCLINED 83 seniors. The conclusion to be drawn from this is that the above five traits form a constellation (as far as our data show) and that the salesmen are distinguished from those who are mechanically inclined in that the former possess these traits to a more marked degree. Of all the rated differences between the two groups, these five traits could most readily be represented by one distribution curve on which salesmen and mechanically inclined people would occupy distinct positions. CHAPTER VI APPLICATION OF RESULTS IN A TOTAL SCORE It is of interest to know how well the two general groups that are dealt with in this study can be differentiated by a total score which takes into consideration the significant individual items. If the items can be combined in such a way as to produce a total score which will clearly differentiate between men of extreme mechani- cal tendencies and those of sales tendencies, we shall have a con- venient mode of discovering the propensities of an individual, and can use this information for vocational guidance along broad lines rather than specific ones,—lines which will probably lead to greater vocational happiness than any other method of vocational guidance can afford. We have found that no single test or other measurement com- pletely differentiates the two primary groups. If the most sig- nificant measurements are combined we shall have a total score which, although it may not differentiate as well as the most sig- nificant individual test, will yield the best combination of differen- tiation and reliability. Although an individual may not conform to his group in getting a high score in a certain test he may make up for this by having all of the interests of his group, and this re- . flected in his total score will place him properly. The extreme in- dividuals will have a greater number of the interests and abilities of their group than will any of the intermediate individuals. Tue MetTHOD The method of combining scores offers an interesting problem. I have followed with some modifications, the procedure of Ream (17). The ratings and all the questionnaires but 2 and 4 were left out of consideration because of the difficulty of gathering the ma- terial and scoring the blanks in any future applications of the method. THE SOCIALLY AND THE MECHANICALLY INCLINED 85 The application of the method of combining scores to the ques- tionnaires has already been explained (7). It need be necessary only to review briefly what that procedure involves. The problem is to discover the significant group differences in answers to particular items in the questionnaires, and to bring these differences together into a total scoring method by which their cumulative differentiating power will be a maximum. The steps in the solution of this problem are as follows: 1. For each of the two groups to be compared, make tables showing the frequency with which each symbol in the question- naires is checked. 2. Select for statistical treatment those symbols which seem to show significant differences in the proportions of the two groups checking them. 3. In the case selected, determine the difference in proportion. 4. Determine the standard error of the difference in proportion by the formula given by Yule (formula 6, p. 269). The size of this standard error is an index of the probability of the difference in proportions arising through chance due to the fact that we have merely sampled the total number of persons engaged in the two types of occupation; in other words, it is an index of the univer- sality of our findings. 5. List the cases in which the difference in proportions is at least twice as great as its standard error. These items should all re- ceive equal weight in the total score. Yule claims that if the differ- ence in proportion does not exceed three times the error of the difference, it may be obliterated by an error of simple sampling on taking fresh samples in the same way from the same material. But for practical purposes the probability of the difference being ob- literated is very little less if the error is twice the difference in pro- portion, and this enables us to use a great many more items. 6. Determine which items will enter into the total score in a pos- itive way and which in a negative way. This will depend on which group it is desired to favor in the total score. Thus, if we wish to “favor” the sales group, we assign positive values to symbols which are checked by a larger proportion of the salesmen than the students of mechanics, and negative values to symbols where the 86 MAX FREYD opposite condition exists. The resultant total scores will reveal “higher” scores on the part of the salesmen, but this does not in- dicate a superiority, since the scores are merely relative, the main object being to differentiate the groups. It does not matter which group we select to assign the higher scores, but having selected one, plus and minus signs should be consistent throughout. All symbols should be given equal value, that is -+-1 or —1; since the criterion for inclusion is high (see 5 above) no weighting of symbols is necessary. 7. The total score for any person will be the algebraical sum of the positive and negative values attached to the significant items (symbols) which he checks. The application of this method to test scores is fairly obvious. In the case of the two primary groups, critical scores were found by inspection which divided the distributions for the two groups into sections in which there were significantly different propor- tions of the members of the groups. For example, critical scores were set at 2 and 11 for the number of contrast responses in the Kent-Rosanoff Test. Seventeen per cent of the sales group and 53 per cent of the industries group obtained scores of 2 or less. Forty per cent of the sales group and 7 per cent of the industries group obtained scores of 11 or more. Both of these differences are significant and consequently enter into the total scores. The sig- nificances of the differences in proportion may be determined in the same manner and by the same formula as differences in propor- tions checking the symbols in the questionnaires. Thus, scores. of II or more in the number of contrast reponses may be treated the same as checking D after an item in a questionnaire; scores of 2 or less may be treated as checking L, and scores of 3 to Io inclu- sive as checking ?. The significant differences are in the propor- tions checking L and D (scoring above 11 or below 2). Setting critical scores corresponds to the second step in the above outline. A possible objection to this scoring method is that it leaves out of consideration in most cases the majority of the groups;that is, the majority of both groups may obtain scores of 3 to 10 inclusive in the number of contrast responses. This objection is not valid for the following reasons: THE SOCIALLY AND THE MECHANICALLY INCLINED 87 I have not set critical scores nor included in the total score items of questionnaires, no matter how significant the differences in pro- portion may have been, unless a fair proportion of the total num- ber of individuals were taken into consideration. There would be no point in setting a critical score if only two members of one group and none of the other group were beyond it, or accepting an item (in a questionnaire) which was checked by 2 per cent of one group and 8 per cent of the other. It would require a great number of such partial scores to obtain a total score which would differentiate. f Those whose scores do not fall into any of the compartments formed by the critical scores and who consequently do not receive either a plus or a minus score for that measure, are not totally ignored in the composite score for that reason. Their score for that test is zero. This makes the dividing line between the two groups in the total score tend to be around zero, a convenient place for it. It also makes scoring a simpler matter. The method could be made more obvious by assigning to all those who score below 2 in the number of contrast responses a score of 1 toward their total score, assigning 2 to those who score from 3 to 10, and assigning 3 to those who score 11 or above. A third answer to this objection is that even if a certain propor- tion of the groups were ignored in the total score because of their scores in any individual measurements, we should still have a logical basis for differentiation with our total score. We may assume that the factors which operate to cause one to go into an occupation are very diverse, and that any two or three are suf- ficient to place him in that occupation. Then as long as an indi- vidual falls into compartments showing significant differences in two or more tests or answers to questionnaires, he shows evidence of having been influenced by those two factors to place him in the occupation in which he finds himself. Only the extreme individuals are influenced by all of the factors. RESULTS The individual items from the two questionnaires and the tests which entered into the final score for differentiating the industries 88 MAX FREYD seniors from the thirty successful life insurance salesmen, do not in every case differentiate the secondary groups from each other, but the results on the secondary groups were not tabulated until the final scoring method was drawn up. In determining differences in proportions of symbols checked in Questionnaire 4, L! and L were combined and D and D! were combined, and not tabulated separately. The reason for doing this was that another form of the blanks in which only one kind of L and D occurred was given to most of the secondary groups, and if we wished to score them according to the final scoring method we should not have been able to do so unless we made this change. The items which entered into the total score for differentiating the sales from the mechanical groups are given in Table 4 on the following page. The scoring method was decided upon by com- paring the two primary groups, and the results of this comparison are in Table 4. In obtaining the total scores the sales group was favored; that is, where a greater proportion of salesmen than industries students checked a given symbol, checking that symbol counted +-1 toward the total score, and where the opposite relationship held, checking the symbol counted —1 toward the total score. | One member of the primary sales group failed to fill out several of the forms, and his figures are omitted entirely in the presenta- tion of results. Three members of this group also failed to com- plete parts of Test IX. Fig. 9 shows the results of the composite scoring method on the ~ two primary groups. In this figure are shown the total composite scores, composite scores on tests alone, and on Questionnaires 2 and 4, separately and combined. Each component of the total com- posite score is very effective in differentiating the two groups." The total score is, however, more effective than any of the compo- 1 The only check we have on the reliability of these scores is the following: Eleven men in the Division of Cooperative Research at Carnegie Institute of Technology filled out Questionnaire 4 twice at an interval of one month. Their scores were obtained on those items which enter into the total score and occur in that questionnaire. Of the eleven, five obtained the same total score on this questionnaire, and four others gained or lost one point. ; THE SOCIALLY AND THE MECHANICALLY INCLINED 89 TABLE IV Items which Entered into the Total Scoring Method for Differentiating Sales- men from the Mechanically Inclined.

Another interesting point is that the most favorable critical score for dividing the groups is near the zero point in each case. The total composite score was obtained for the secondary groups. The interquartile ranges are presented in Fig. 10.

The sales groups include the entire membership of the Life Insurance Schools of Spring, 1920-21, and Fall and Winter, 1921-22; and the salesmen of the Harrison Real Estate Corporation, the Burroughs Adding Machine Company, and the Cleveland Discount Company. For further information about these groups, see Chapter I. The Westinghouse seniors were a composite group, some being salesmen and some mechanics. Most of them neglected to state their occupation. Of the three making the lowest scores, two were draftsmen (the only two in the group), and of the three making the highest positive scores, one was a salesman and the other a sales correspondent (the only ones in the group). The outstanding feature of this figure (Fig. 10) is the fact that there is no overlapping of the interquartile ranges of the sales and mechanical groups. The overlapping of the actual distributions is less than one-fourth, which may include all those individuals who are vocationally misplaced. Another feature is the fact that the best critical score remains around the zero point. There is a tendency toward bimodality in the distribution curve of total scores for all groups (Fig. 11c) although the tendency is not marked. The modes correspond very roughly to the medians of the two main groups. Fig. 11a and Fig.11b show the complete distribution curves for the mechanical and sales groups. It is clear from the curve for the mechanical group that if there were more individuals in the group its mode would be around —3. If the numbers in the two groups were equal the bimodality of the curve for all cases (Fig. 11c) would be accentuated. SUMMARY Two important points are presented in this chapter. (1) A method is explained for arriving at a scoring method for differentiating groups. : (2) A scoring method for differentiating salesmen from men who are mechanically inclined, is presented. The main purpose of the chapter is to show how the results ob- tained in this study may be applied to practical problems in voca- 93 THE SOCIALLY AND THE MECHANICALLY INCLINED Las ot Ot 8 9 4 FA Q Z v 9 8 Olie.claeeyt ot *(saseo Ivy) Us [[V 1OF saz09S [eIOL JO aainy voNysiqg 02 JII “OI og OF + = Videe.dts Ola 8 9 v Z ) 2 id 9 8 ol ° oT *(sased Sgz) UIWISI[VS ][[Y OF sat09g 02 [®1O], JO VAIN UOTNQIySIG ql “Oly og *(sosed PzZ1) sdnoist) “Yoda IOF S9tOIS [eJO], FO VAIND UOTINAIIYsIC DII “Oly 61095 sesso Jo Iequni 04 MAX FREYD tional guidance. By the use of this scoring method, we can discover the inclinations of any individual as regards mechanical or social types of occupation, and advise him accordingly. From the standpoint of the mere study of the personality of any individual the results of this scoring method may be of interest. The scoring method not only places the individual vocationally, but places him with regard to constellations of personality traits and interests. CHAr Ti RsVil SUMMARY AND CONCLUSIONS There is nothing in the results submitted to prove the existence of types of people; rather can we conclude that extremes exist with regard to any trait or combination of traits. If we assume the normal probability distribution for any trait or combination of traits, the persons lying beyond sigma, to be dogmatic, may be said to belong to extremes. We find some evidence for a bimodal distribution, which Thorndike sets up as a criterion of types, in the distribution curves of total scores. In general, though, the evi- dence is against the existence of types. The great majority of peo- ple have no pronounced tendencies which warrant their placement in extremes, but only show leanings toward one or another of ex- tremes. Leanings toward extremes are of psychological value, and in a sense this study has shown how they may be approached and utilized. The importance has been shown of a distribution of ten- dencies with mechanical inclinations at one extreme shading off into social inclinations at the other extreme, and to some extent the personality traits correlated with these tendencies have been deter- mined. The measures of personality used in this study are open to criti- cism on several points. The test results may be interpreted as measures of any one or more of a number of traits. The question- naires may have been completed without regard for the truth. The ratings may have been invalidated because of a bias in favor of the persons rated, or because of errors of self-estimation. These objections are not fatal, since the interpretations of the function measured by any test will vary within rather narrow limits, and the interpretation placed on the tests cannot therefore be greatly in error; the purpose of the questionnaires was not so obvious as to indicate the most profitable direction of falsification; and if the raters were biased in favor of the subjects of the experiment, this 06 MAX FREYD bias would be a factor common to all groups of raters and if neces- sary could be corrected for, but in any case this would not change the standing of any group relative to the other groups. If the ratings are not very accurate for any individual, they are at least sufficiently accurate for group comparisons. The most effective contradictions to the criticisms of the means by which the results were obtained, come from the fact that the tendency is for the re- sults obtained with the three sets of forms to corroborate each other, and from the fact that the resulting description of the per- sonality of the extremes of the two groups is psychologically consistent. The following table summarizes the basis for the conclusions drawn as to differences in personality between the two groups.

The pos- sible explanation of the factors which operated to place the men in the opposing extremes of occupation and personality are as fol- lows: (1) The mechanically inclined men were more often of non- American or non-British extraction. Not being of the same stock THE SOCIALLY AND THE MECHANICALLY INCLINED 97 as the majority of the inhabitants of the country, and not having the advantages of training by parents of that stock, they were handicapped in their adaptation to society and tended therefore to enter occupations where mechanical rather than social ability was of prime importance. (2) The early family history of the mechanically inclined men points to a less healthful and cheerful environment than that of the salesmen. The indications are that the mechanics students were dissatisfied with the financial status of their families, the charac- teristics of their companions, and the generally cheerless tone of their environment. They tend to claim they were treated worse than their brothers and sisters, and engaged in more fist-fights than the salesmen. (3) Maternal influence was exerted predominantly on the me- chanically inclined men and paternal influence on the salesmen. How these influences shaped their personality is an obscure psycho- logical problem. Without going unnecessarily deeply into the pos- sible psychoanalytic explanation, the conclusion seems warranted that the mechanics student was very early rebuffed by his human environment, owing perhaps to a greater mechanical than social intelligence, and subjected himself largely to the influence of the person who naturally took the deepest interest in him,—his mother. The mother’s influence may have caused him to become less vig- orously adapted’ toward society, but a more plausible interpreta- tion of the facts is that the same factors which caused in the me- chanics student an attachment to his mother, gave rise to his per- sonality traits and caused him to enter a mechanical occupation. The influence of the mother may be accepted as an intensifying factor in shaping personality, and as subordinate to the fact that a greater proportion of the men were of foreign stock and in general grew up ina less fortunate environment than the salesmen. There is nothing to indicate that race is responsible for choice of occu- pation or for personality differences such as we have been study- ing. We should probably find socially inclined and mechanically inclined individuals distributed in the same proportions in every race and nationality, but we should also expect to find among a submerged minority of different stock a greater proportion of men 98 MAX FREYD of mechanical inclinations, simply because they have not the train- ing, appearance, and other qualities necessary to exert social in- fluence. In America, especially, there is a marked tendency to look with distrust on foreigners or those bearing foreign names. (4) There remains, however, a large per cent of men of me- chanical tendencies who are of native stock. The explanation given in the preceding paragraph will not account for the differences be- tween them and the salesmen. The most suitable explanation is to describe them as lacking in social ability and possessing mechanical ability, and the salesmen as possessing social ability and lacking mechanical ability. Thorndike (21) postulates three kinds of intel- ligence: mechanical, social, and conceptual, represented among others by mechanics, salesmen, and engineers, respectively. The mechanics students may dominate in mechanical intelligence and be weak in social intelligence, and the salesmen display the opposite tendency. It is the writer’s belief that conceptual intelligence is not of a distinct sort, but displays itself in both mechanical intelligence and social intelligence. Social intelligence may be conceived as the ability to manipulate human beings so as to accomplish definite ends, in contradistinction to mechanical intelligence, which is the ability to manipulate machines. But conceptual intelligence is de-: manded in both of these processes. Social intelligence and mechan- ical intelligence are the only ones which may be distinguished be- havioristically. Social intelligence is perhaps best illustrated by pointing to the politician, the orator, or the salesman. The ma- chinist or the draftsman illustrate the possession of mechanical intelligence. The reactions of human beings and machines are of not quite the same nature, and require a different technique. On its passive side, social intelligence is shown in social suggestibility, identification with the crowd in associations and beliefs, in suscep- tibility to “being sold,” in apparent credulity. The credulous per- son, or the person who appears to be credulous, is more apt to make a favorable impression on others than the person who is open in his disbeliefs. (5) At least one of the traits displayed by the mechanics stu- dents may be compensatory in nature. I refer here to conceit, ap- parently measured by the means explained in Chapter II, and also THE SOCIALLY AND THE MECHANICALLY INCLINED ~—99 shown in the statements of the industries students that they won a majority of the fights they engaged in as children. A realization on the part of many of the mechanics students that they lacked certain of the elements of social ability may have wittingly or un- wittingly caused them at least to assume the attitude of possessing those elements. Conceit is a typical compensatory attitude. Incre- dulity may in a sense be compensatory. It is an attitude assumed by those who realize their weaknesses and are consequently on guard that no one takes advantage of them. It is less easy to find examples of compensation among the salesmen, since it is a lack of social adaptation that is usually compensated for. Lack of mechanical ability would be less often a cause of social mal-adapta- tion than lack of sociability, and it is the realization that one is socially poorly adapted that gives rise to compensation. Persever- ance on the part of the salesmen may possibly be a compensatory mechanism, and their lack of conceit may well be considered as over-correction lest they be judged as conceited in the slightest degree.
