Personality differences uncovered between students at different US universities – Research Digest

larger universities tended to have more extraverted students; more urban and diverse universities had more open-minded students;  universities requiring letters of recommendation had more agreeable students; public colleges had less agreeable students than private colleges; and more expensive colleges had higher trait Neuroticism. Differences like these could reflect students with particular personality profiles being drawn to particular institutions; selection could be at play, in the sense of university selectors showing a preference for particular personality types; and also students’ personalities could be shaped by the culture of their university.
