The WEIRDest People in the World

Joseph Henrich · 2020

A familiar way of thinking is not necessarily a universal one.

Big Idea

Henrich argues that Western psychology is historically unusual and connects it with changes in kinship, institutions, and cultural learning.

Sampling

Western, educated, industrialized, rich, democratic populations do not represent all human psychology.

Cultural learning

Practices and institutions can shape thinking and behavior over generations.

Kinship

Henrich emphasizes historical family and marriage arrangements in his explanation.

Institutional feedback

Changing social structures and psychological tendencies can influence one another.

Argument limits

This is a broad, debated historical account, not a ranking of peoples or cultures.

Notooo Take

Ask who participated in a study before treating its result as universally human.

One Thing to Keep

A familiar way of thinking is not necessarily a universal one.
