In a fascinating conversation, Joseph Henrich, a Harvard professor specializing in cultural evolution, unveils the biases introduced by focusing on WEIRD populations in psychological research. He proposes a bold theory linking cultural practices, such as the Catholic Church's stance on kinship, to the emergence of modern Western psychology. The dialogue delves into empathy, moral perspectives across cultures, and how shifts in family structures reflect broader societal changes. Henrich challenges us to rethink our understanding of identity and human behavior through diverse cultural lenses.
Psychological research has focused on WEIRD populations, skewing our understanding of human psychology.
Cultural differences influence time perception, evolving from fluid interpretations to linear measures.
Literacy affects brain hemispheric specialization, shifting functions towards language processing.
Belief in free will varies across cultures, impacting behavior and cognitive processes.

Cultural Insights and Psychological Research
Psychological research has predominantly focused on western educated, industrialized, rich, and democratic populations (WEIRD) when studying behaviors and cognitive traits. These populations have been found to be outliers in terms of psychology and brain functions, impacting how studies are interpreted. Joseph Henrich emphasizes how this narrow focus has skewed our understanding of psychology and how cultural factors influence our behavior and cognition.
Evolution of Time Perception
The perception of time has evolved differently across cultures, influenced by historical practices and societal norms. Time as a concept has shifted from more fluid interpretations to a linear and quantifiable measure, particularly emphasized in western cultures. The dissemination of mechanical clocks and the development of wage labor further illustrate this transition towards a more precise understanding and utilization of time in society.
Brain Hemispheric Specialization
Neuroscientific studies reveal that literacy and cultural practices have a significant impact on brain hemispheric specialization. As individuals become literate, facial recognition shifts to the left hemisphere due to the localization of language centers. Literate societies' brain functions align more with reading and language processing, altering traditional patterns of object and facial recognition in the brain's neural pathways.
Free Will Perception and Decision Making
The concept of free will varies across cultures and is influenced by societal norms. In weird populations, the belief in free will correlates with increased charitable behavior and delayed gratification. Research suggests that cultural norms play a crucial role in shaping individual perceptions of decision-making, emphasizing the interplay between culture, behavior, and cognitive processes.
Impact of Kinship Structures on Societal Development
The podcast discusses how the evolution from extensive kinship to clan-based social structures impacted the scaling up of societies. It explains how kin ties, clan loyalty, and inheritance rules influenced social networks, psychology, and behavior, emphasizing the shift towards larger cooperative groups.
Role of Church in Shaping Social Networks
The episode delves into the church's influence, particularly the Western Church's strategic decisions that shaped societal structures. It highlights how the church's policies regarding cousin marriage, inheritance rules, and family systems led to the evolution of monogamous nuclear families and the development of voluntary institutions.
Weirdness of Protestantism and Societal Impact
The podcast explores how Protestantism accelerated individualism and innovation by promoting individual interpretation of religious texts, education, and societal structures. It discusses the Protestant work ethic, literacy initiatives, and the impact on democracy, capitalism, and intellectual exchange, underlining the link between cultural norms, psychological adaptations, and societal progress.
We all know stereotypes about people from different countries; but we also recognize that there really are broad cultural differences between people who grow up in different societies. This raises a challenge when most psychological research is performed on a narrow and unrepresentative slice of the world’s population — a subset that has accurately been labeled as WEIRD (Western, Educated, Industrialized, Rich, and Democratic). Joseph Henrich has argued that focusing on this group has led to systematic biases in how we think about human psychology. In his new book, he proposes a surprising theory for how WEIRD people got that way, based on the Church insisting on the elimination of marriage to relatives. It’s an audacious idea that nudges us to rethink how the WEIRD world came to be.
