This episode of Hidden Brain explores how ancient cultural inventions, such as mechanical clocks and the Catholic Church's marriage rules, continue to shape modern psychology, behaviors, and societal structures. Anthropologist Joseph Henrick reveals that practices like punctuality, individualism, and the nuclear family are historically unique products of specific cultural evolution, not universal human traits.
