Both optimism and pessimism are strongly influenced by environmental factors, including family environment.[4] It has been suggested that optimism may be indirectly inherited as a reflection of underlying heritable traits such as intelligence, temperament, and alcoholism.[26] There is evidence from twin studies that show, for instance, that the inherited component of the dispositional optimism is about 25 percent, making this trait a stable personality dimension[27] and a predictor of life outcomes.[28] Its genetic origin, which interacts with environmental influences and other risks, also determines the vulnerability to depression across the lifespan.[29] Many theories assume optimism can be learned,[6] and research supports a modest role of family-environment acting to raise (or lower) optimism and lower (or raise) neuroticism and pessimism.[4]	./cache/en-wikipedia-org-3522.html	./txt/en-wikipedia-org-3522.txt
