Researchers have linked personality traits to
diverse outcomes such as experiential buying tendencies, political orientation,
natural language use, preference in pets, the state of one’s personal living
space, and even more important life outcomes such as divorce, morbidity, and
occupational attainment. Some recent data suggests that people who find
themselves in disease-ridden environments tend to be less open and extraverted,
presumably because this makes them less motivated to explore and interact with
others (which reduces the chance they will become infected).
