Copying rituals has allowed cultural groups to proliferate over time. Rare, traumatic rituals produce strong cohesion in small relational groups, whereas daily/weekly rituals produce cohesion in expandable communities. This study presents a theory of how these two ritual modes have influenced history over thousands of years.
The book explores how our evolved psychological biases—conformism, religiosity, and tribalism—have shaped human behavior throughout history, driving both remarkable advancements and current crises. Renowned anthropologist Harvey Whitehouse delves into diverse cultural contexts, revealing how these biases have led to significant societal transformations while also contributing to today's political polarization and environmental challenges. By understanding our inherited traits, Whitehouse proposes a new approach to address pressing global issues, offering insights into our past and potential future.
