Joseph Henrich — Humans defeated smarter species with cultural evolution

Joseph Henrich's research posits that human progress relies on a "collective brain" where cultural knowledge and institutional frameworks like the Roman Catholic Church's dissolution of kinship systems drove Europe's Industrial Revolution. This perspective reframes human history as a series of expansion-collapse cycles where population density, social interconnectedness, and the offloading of cognitive tasks into culture determine innovation rather than individual intelligence or genetic mutations. By contrasting stable but isolated societies with fragmented, mobile populations, the analysis highlights how institutional erosion and the forced integration of strangers create the conditions necessary for scientific and technological breakthroughs.
