About this episode

This episode explores the fragility of our sense of control over our minds and how our brains function as prediction engines.

Are we really in control of our own minds? Research suggests our sense of control may be far more fragile – and far stranger – than we imagine. From moments when the body seems to act without us, to the eerie ways our brains can warp what we think we’ve heard, scientists are uncovering a picture of the mind that’s anything but straightforward. And beneath it all lies a surprising discovery: the brain is less an observer of reality than a prediction engine, forever guessing what comes next.
