Jonathan Haidt | The All-In Interview

The episode launches "the All-In Interview," in which two hosts question one guest instead of four against one. The hosts describe it as an experiment, perhaps ten times a year.

Friedberg summarizes Jonathan Haidt's work as evolutionary biology meeting modernity. Haidt accepts the label but widens it: evolutionary psychology, anthropology, cultural psychology and a little sociology, applied by someone bothered when institutions malfunction. He lists democracy, universities (The Coddling of the American Mind, Heterodox Academy) and now family life for people born after 1995.

it took generations for things like the Bible or the Quran or monarchical systems to kind of permeate

That line comes from the host's contrast: digital media now shows anyone the lives of others instantly, and the right message can shift a brain quickly.

Haidt says evolution is slow, while sociology began with the upheaval of the Industrial Revolution. Early sociologists such as Weber and Durkheim sensed that something deep about living together was changing in ways nobody understood.

He says he is not anti-tech, but notes that tech firms, Meta among them, employ social psychologists, sometimes for manipulation, while he has never heard of a company employing a sociologist.

changing the basic conditions of America's liberal democracy in ways that I think it may not survive

This is Haidt's own judgment, offered as a cause for concern. The conversation does not test it.

Friedberg traces a sequence: app builders borrowed game mechanics such as levels and scores, then handed gamification to machine learning, which is "really TikTok." Haidt compares the shift from television to algorithm-driven media with the shift from heroin to fentanyl, because targeting replaces mass marketing judged by Nielsen ratings.
