When Culture Stops Evolving: Civilisational Drift and the Death of Adaptive Culture

In this episode of Over the Mountains, Rufus is joined by economist and futurist Robin Hanson, who reshapes our understanding of cultural evolution and civilizational collapse, highlighting the importance of curiosity and original thought.

Hanson argues that culture is humanity’s true superpower — a Darwinian process that has historically kept our values and norms fitted to reality. But over the last three centuries, the four key conditions that make cultural evolution work have each quietly shifted into failure: diversity has collapsed into a global monoculture, selection pressures have weakened as wealth insulates us from consequence, the pace of change has outrun our ability to adapt, and internally driven cultural shifts now steer us away from fitness rather than toward it.

“Cultural evolution is the thing that gave you everything you value.”

The result, Robin suggests, is a civilisation drifting back toward its default human state, as he puts it plainly, “lazy, selfish, and myopic.” Low fertility, rising mental illness, drug deaths, and the cultural rejection of transformative technologies like nuclear energy are not isolated crises. They are symptoms.

Robin points toward Futarchy as a solution — a radical reimagining of governance built on prediction markets and the principle of “vote on values, bet on beliefs” — and argues that what civilisation ultimately needs is a sacred goal: something vast enough and serious enough to demand real sacrifice.

This is a conversation about evolution, governance, and what it means to build something worth surviving for.
