"Decades of social-psychological research can be boiled down to one insight: if we want to predict someone’s behavior, we are better off knowing where they are rather than who they are. Personality is a poor predictor of behavior, and most of the time our actions are determined by situational pressures, not personality characteristics. Knowing about situations tells us a lot more about what people will actually do than knowing more about the people, themselves."
