Joseph Henrich on how religion changed sex, families and culture

What made some societies so individualistic, so democratic, and so rich? The short version of Joe Henrich’s answer is: religion. By undermining kin-based networks, universalizing religions (especially Western Christianity) prompted the “big innovation” of impersonal trust, altered the Western brain and laid the foundations for free markets, geographical mobility and democratic institutions. In other words, some people became WEIRD (Western, educated, industrialized, rich, democratic). We discuss how the concept of coevolution helps to get us past the tired nature v. nurture distinction, the role of culture in shaping our biology, how polygamy causes a “math problem of surplus men”, the rise of the incel movement along with feminism, how monogamous marriage lowers testosterone (and why that’s a good thing), The Life of Brian, morality and politics and much more.
