The WEIRDest People in the World

'A landmark in social thought. Henrich may go down as the most influential social scientist of the first half of the twenty-first century' MATTHEW SYED Do you identify yourself by your profession or achievements, rather than your family network? Do you cultivate your unique attributes and goals? If so, perhaps you are WEIRD: raised in a society that is Western, Educated, Industrialized, Rich and Democratic. Unlike most who have ever lived, WEIRD people are highly individualistic, nonconformist, analytical and control-oriented. How did WEIRD populations become so psychologically peculiar? What part did these differences play in our history, and what do they mean for our collective identity? Joseph Henrich, who developed the game-changing concept of WEIRD, uses leading-edge research in anthropology, psychology, economics and evolutionary biology to explore how changing family structures, marriage practices and religious beliefs in the Middle Ages shaped the Western mind, laying the foundations for the world we know today. Brilliant, provocative, engaging and surprising, this landmark study will revolutionize your understanding of who - and how - we are now. 'Phenomenal... The only theory I am aware of that attempts to explain broad patterns of human psychology on a global scale' Washington Post 'You will never look again in the same way at your own seemingly universal values' Uta Frith, Professor of Cognitive Development, University College London

“The weirdest people in the world” - has a very good roots cause analysis of all this.

Basically banding into groups and guarding against outsiders is the default human behaviour. It just works that way if you do a game theory analysis of our social structures. They usually don’t scale too well, but that’s what we revolved to do as social creatures.

It’s actually and very counter intuitively the Catholic Church that lead us to individualism, common laws, nationalism, even the Industrial Revolution and the scientific method.

It sounds bizarre but if you follow the historical logic, in a round about way it has paved the way for the modern world, which the rest of human civilisation was forced to adopt, either to compete or at gunpoint.

There are few books I read in a year that change the way I look at the world, “The Weirdest people in the world” was definitely one of them.

Can’t recommend the book that coined this acronym enough: The WEIRDest People in the World Book by Joseph Henrich.

It is such an eye-opening piece that explains so much of the world around us. He’s an anthropologist that goes into the psychology of it all. Touching on points like how religion plays a part in shaping the America of today and even how humans are worst at discerning faces today because we need to discern letters and words and dedicate brain power for that.

There are so many interest studies mentioned there, one that really stuck with me is how Protestant-raised Americans will work harder for the next day after having (reasearch-led) incestuous thoughts when compared to Catholics and Atheists.

He explains how monogamy is to blame for a lot of our western views today, and how Mormon towns in Utah were affected by not having monogamy as the basis of society (women there tend to prefer to be 2nd wives of a better man rather being the only wife of a lower-ranking man).

One of the wildest claims in there is the one that the north of Italy is more developed today because it was part of the Holy Roman Empire while the south wasn’t. About a thousand years separate these and he finds effects still. Mostly in connection to the spread of read/write to the public being a core tenant of Protestantism.

Anyway, this is not a summary of the book but instead a few points from it that really stuck with me after reading it. Fascinating stuff

Agree. The book "WEIRDest" people in the world was kind of eye-opening in arguing that the Western world (especially the US) is unique (both in time, and geographically) in being so individualistic.

And it's getting worse. Decline of the local church or equivalent religious community, decline of even the workplace especially after Covid, etc. And of course, social media giving people a way to consume time and feel some (fake) version of being connected.

My wife and I moved our kids from the US back to our country of origin last year. Partly because we wanted to be closer to family. But partly because we didn't want them growing up in a society that lacks community and social fabric.

You might enjoy this as well, similar big picture and fascinating, but a bit more scientific and focused on the human element.

It’s been probably a year since I read The WEIRDest People in the World by Joseph Henrich, but the ideas in there have really stuck in my head.

The WEIRD acronym stands for Western, Educated, Industrialized, Rich, and Democratic. The thesis is that the Christian Church inadvertently created modern society by prohibiting polygamy and cousin marriage.

The topic of polygamy is what’s really stuck in my head. Polygamy is a more natural state for civilized human societies than we think it is. It may be to women’s advantage to choose an “elite” spouse she has to share because it could mean a better quality of life for her and her children than the alternatives. Chris Hemsworth could have two dozen wives if it were legal and social acceptable (and he wanted to), and his wives might be happy with that. But the downside (or one of them) is that it creates huge imbalances in society—men find it really hard to find a mate. They then do risky stuff to make it into the elite to try to attract a mate—steal to accumulate wealth or kill potential romantic rivals.

This isn’t in the book, but it made me think—are we back in that same position now? Polygamy isn’t *technically* legal or common, but you still have plenty of people who have many romantic partners—just not at the same time. We know the what the activity of dating apps looks like—a very small subset of “elite” men get an outsized proportion of likes and matches from women. It’s slim pickings for the rest of the men. Are men, unable to find a mate, going to resort to risky behavior to try to make it into that subset that are able to attract women?
