Human brains don’t just perceive reality—they invent it. In this episode of Science Quickly, cognitive neuroscientist Daniel Yon speaks with host Rachel Feltman about how perception is an active process of prediction in which the brain constructs theories about the world that can sometimes lead us astray. Drawing from his book A Trick of the Mind, he reveals why this “hallucination” of reality is not a flaw but a fundamental feature of how we navigate the world.
