Joseph Henrich, Harvard University
The WEIRDest People in the World
Over the last few decades, a growing body of research has revealed not only substantial global variation along several important psychological dimensions, but also that people from societies that are Western, Educated, Industrialized, Rich and Democratic (WEIRD) are particularly unusual, often anchoring the ends of global psychological distributions. To explain these patterns, I'll first show how the most fundamental of human institutions—those governing marriage and the family—influence our motivations, perceptions, intuitions and emotions. Then, to explain the peculiar trajectory of European societies over the last two millennia, I lay out how one particular branch of Christianity systematically dismantled the intensive kin-based institutions in much of Latin Christendom, thereby altering people's psychology and opening the door to the proliferation of new institutional forms, including voluntary associations (charter towns, universities and guilds), impersonal markets, individualistic religions and representative governments. In light of these findings, I close by arguing that the anthropological, psychological and economic sciences should transform into a unified evolutionary approach that considers not only how human nature influences our behavior and societies but also how the resulting institutions, technologies and languages subsequently shape our minds. 
Joseph Henrich's research focuses on evolutionary approaches to psychology, decision-making and culture, and includes topics related to cultural learning, cultural evolution, culture-gene coevolution, human sociality, prestige, leadership, large-scale cooperation, religion and the emergence of complex human institutions. Methodologically, he integrates ethnographic tools from anthropology with experimental techniques drawn from psychology and economics. His area interests include Amazonia, Chile and Fiji.
