Are human behavioral studies giving us the complete picture? Joseph Henrich says no. As a Harvard professor of evolutionary biology, he argues that our understanding of human nature is skewed by the fact that the vast majority of people who volunteer to take part in studies are educated Westerners, who remain a psychologically peculiar crop. Henrich joins Walter Isaacson to explain his theory and give a preview of his new book, "The WEIRDest People in the World." Originally aired on November 3, 2020.
