Joseph Henrich on Cultural Evolution, WEIRD Societies, and Life Among Tribes | Convos with Tyler

Cultural Impact

Joseph Henrich explores how cultural transformations have historically influenced economic growth. He highlights the role of the Western church in reshaping social structures, which fostered individualism and paved the way for secular institutions and economic development. Henrich notes that the church's marriage and family program, which began in 600 in Kent, dissolved complex kinship groups and promoted broader social connections 1. This transformation contrasts with China's historical stagnation, attributed to its strong patrilineal clan system and cousin marriage, which hindered individualism and innovation 1.

The church is the first mover in that account.

Henrich also touches on assortative mating, suggesting that modern societies offer more opportunities for like-minded individuals to marry compared to small-scale societies 2.

   

Cultural Norms

Henrich examines how cultural norms influence market behaviors and economic adaptation. He discusses how genes have been selected over millennia in response to agriculture, citing examples like lactose tolerance and blue eyes in Baltic populations 3. These genetic adaptations are intertwined with cultural evolution, shaping how societies cooperate and function at the state level.

It's individual, garden variety selection responding to a culturally constructed environment.

--- Joseph Henrich

Henrich argues that cultural differences persist over generations, as seen in the cooperative traits retained by migrants' descendants in the United States 3. This persistence suggests that cultural heritage, rather than genetics, plays a significant role in shaping economic behaviors.
