Evolution. Society works better when most people fall in line with the major consensus narrative. Even a society with a suboptimal strategy that everyone follows is better than a society full of second-guessers that doesn't get anything done. That's not to say that you need everyone to be a mindless drone, but just like reinforcement learning works best with a healthy balance (usually like 90/10) of exploitation and exploration, society works best when a few people explore new options and the majority follows the emergent consensus.
