“Why Are We in the West So Weird? A Theory

According to Joseph Henrich’s book, it was the advent of Protestantism, aided by the invention of the printing press, that brought along the spread of literacy and altered the workings of our brains.

How the West Became Psychologically Peculiar and Particularly Prosperous
By Joseph Henrich


The world today has billions of inhabitants who have minds strikingly different from ours. Roughly, we weirdos are individualistic, think analytically, believe in free will, take personal responsibility, feel guilt when we misbehave and think nepotism is to be vigorously discouraged, if not outlawed. Right? They (the non-WEIRD majority) identify more strongly with family, tribe, clan and ethnic group, think more “holistically,” take responsibility for what their group does (and publicly punish those who besmirch the group’s honor), feel shame — not guilt — when they misbehave and think nepotism is a natural duty.


WEIRD folk are the more recent development, growing out of the innovation of agriculture about 10,000 years ago, the birth of states and organized religions about 3,000 years ago, then becoming “proto-WEIRD” over the last 1,500 years (thanks to the prohibition on marrying one’s cousin), culminating in the biologically sudden arrival of science, industry and the “modern” world during the last 500 years or so. WEIRD minds evolved by natural selection, but not by genetic selection; they evolved by the natural selection of cultural practices and other culturally transmitted items.

Henrich is an anthropologist at Harvard. He and his colleagues first described the WEIRD mind in a critique of all the work in human psychology (and the social sciences more generally) built on experimental subjects almost exclusively composed of undergraduates — or the children of academics and others who live near universities. The results obtained drawing on this conveniently available set of “normal” people were assumed by almost all researchers to be universal features of human nature, the human brain, the human emotional system. But when attempts were made to replicate the experiments with people in other countries, not just illiterate hunter-gatherers and subsistence farmers but the elites in Asian countries, for instance, it was shown in many cases that the subject pool of the original work had been hugely biased from the outset.

One of the first lessons that must be learned from this important book is that the WEIRD mind is real; all future investigation of “human nature” must be complicated by casting a wider net for subjects, and we must stop assuming that our ways are “universal.” Offhand, I cannot think of many researchers who haven’t tacitly adopted some dubious universalist assumptions. I certainly have. We will all have to change our perspective.


This is an extraordinarily ambitious book, along the lines of Jared Diamond’s “Guns, Germs and Steel,” which gets a brief and respectful mention, but going much farther, and bolstering the argument at every point with evidence gathered by Henrich’s “lab,” with dozens of collaborators, and wielding data points from world history, anthropology, economics, game theory, psychology and biology, all knit together with “statistical razzle-dazzle” when everyday statistics is unable to distinguish signal from noise. The endnotes and bibliography take up over 150 pages and include a fascinating range of discussions.


This book calls out for respectful but ruthless vetting on all counts, and what it doesn’t need, and shouldn’t provoke, is ideological condemnations or quotations of brilliant passages by revered authorities. Are historians, economists and anthropologists up to the task? It will be fascinating to see.”
