Introverts do better in school than extraverts, particularly in more advanced subjects. Also, students withdrawing from college for academic reasons tend to be extraverts, whereas those who withdraw for psychiatric reasons tend to be introverts. Extraverts prefer vocations involving interactions with other people, whereas introverts tend to prefer more solitary vocations . Extraverts seek diversion from job routine , whereas introverts have less need for novelty . Extraverts enjoy explicit sexual and aggressive humor, whereas introverts prefer more intellectual forms of humor such as puns and subtle jokes.
Extraverts are more active sexually, in terms of frequency and different partners, than introverts.
Extraverts are more suggestible than introverts. Finally, the results of a recent investigation of study habits among introverts and extraverts may be of particular interest to college students. The research examined whether such personality differences are associated with differing preferences for where to study and how to study, as would be predicted by Eysenck's theory. An important implication of such research is that different environmental designs for libraries and residence units might best fit the needs of introverts and extraverts. Eysenck suggests that individual variations in introversion-extraversion reflect differences in neurophysiological functioning .
