- WEIRD: Among the most prominent features that make people WEIRD is prioritizing impersonal pro-sociality over interpersonal relationships. Impersonal psychology includes inclinations to trust strangers or cooperating with anonymous others. Another big one is having high levels of individualism, meaning a focus on the self and one’s attributes. This is often accompanied by tendencies toward self-enhancement and overconfidence. WEIRD people also rely heavily on analytic thinking over more holistic approaches to problems.
