Harvard University to discuss his work on how humans evolved genetically to be a cultural species. Our conversation begins with a discussion of radical interdisciplinarity, or how we need to adopt multiple approaches and perspectives to answer complex social scientific questions. This contrasts with a disciplinary focus, which still dominates most research. Our conversation then turns to discussing Henrich’s wider research agenda, exploring his two most recent books The Weirdest People in the World and the Secret of Our Success, and his current book project, The Collective Brain. Our conversation touches on humans as a cultural species, how the nature vs. nurture binary is false, and how policies regarding marriage and the family implemented by the Roman Catholic Church in the Medieval period shaped psychological variation observed in Western societies, leading to a more individualistic psychology, changes in the nature of Western law, and eventually leading to things like representative government.
