Most people think of cultural differences in terms of race, class, nationality, or religion. Michele Gelfand introduces the concept of 'tight" and "loose", which cuts across all of those other categories. Michele is a distinguished professor of psychology at the University of Maryland, College Park and joins David to discuss cultural diversity from an evolutionary perspective and more, including why the working class cares more about following the rules, the fractal nature of social norms, gamma wave synchrony in response to threat, and the strengths and limits of a tight-loose axis approach.
