This episode explains why superstition continues to exist even in modern scientific societies. It shows that superstitions function as emotional coping tools, reducing anxiety and creating a sense of control during uncertainty. Because rituals comfort the brain, require little mental effort, and are reinforced by culture and memory bias, they persist alongside rational thinking. The episode concludes that superstition survives not from ignorance, but from the human need for reassurance in an unpredictable world.
