Coherence at civilizational scale: mathematical history and gene-culture coevolution.

Coherence at civilizational scale.

The same geometry that holds a nervous system together holds a civilization together — or fails to. Peter Turchin predicted 2020's instability using equations. Elite overproduction, fiscal stress, declining wellbeing: these aren't vibes, they're measurable dynamics with 200-300 year cycles.

Cliodynamics
In 2010, Peter Turchin made a prediction that raised eyebrows: American political instability would peak around 2020. His forecast came from mathematical models tracking elite overproduction, declinin
Gene-Culture Coevolution
Humans are evolutionary freaks. We're the only species with cumulative culture, the only ones whose knowledge builds across generations, the only ones who can transmit complex skills through teaching
