Are climate and personality related?

To test the relationship between ambient temperature and personality, we conducted two large-scale studies within two geographically large yet culturally distinct countries: China and the United States. Using data from 59 Chinese cities (N = 5,587), machine learning and multilevel analyses revealed that individuals who grew up in areas with milder temperatures (i.e., closer to 22 °C) scored higher on personality factors related to socialization/stability (agreeableness, conscientiousness, emotional stability) and personal growth/plasticity (extraversion, openness to experience). These same relationships between temperature clemency and personality factors were replicated in a larger dataset of 12,499 ZIP-code level locations (the lowest geographic level feasible) within the United States (N = 1,660,638).
