If you grew up in a cold weather state - a new study says you're probably less friendly and more introverted than someone who grew up in a warm weather state.
A study published this week in Nature looked at the differences in personality and human growth between people who grew up in warm vs. cold weather.

The study found that people who grew up in colder climate, with an average around 50 degrees, were less agreeable, less emotionally stable and more closed off.
People who grew up in climate with an average around 72 degrees were more outgoing, friendlier and more willing to explore new things.
"Growing up in temperatures that are close to the psychophysiological comfort optimum encourages individuals to explore the outside environment, thereby influencing their personalities," authors of the study wrote.
"There is ample evidence that ambient temperature affects agri-cultural activities (when and what to farm), individuals’ migration decisions, and pathogen prevalence. Thus, ambient temperature likely has important explanatory power for geographical variation in personality. Overall, our temperature clemency perspective of personality offers a mechanism for why and how macro-level envi-ronmental forces might shape individual-level personality."
