It's an old-school episode as David and Tamler dive into some intriguing research on the origins of cultural differences. Two neighboring communities in communist China were assigned to be wheat farmers and rice farmers. Seventy years later, the people in the rice farming communities showed signs of being more collectivist, relational, and holistic than the people in the wheat farming communities. Plus, we have some questions about a new study on censorship and self-censorship among social psychologists.
