The Reason You Feel Watched When Nobody's There

You're alone. Your neck prickles. You turn around - nobody's there. So what exactly just happened? The answer isn't a ghost story. It's a machine in your brain that has been running for hundreds of thousands of years, and it's doing exactly what it was built to do. This video explores the science of feeling watched: the neurons David Perrett found that fire only when eyes point at you, why humans are the only primate out of hundreds with a bright white sclera (and what Michael Tomasello's cooperative eye hypothesis says about why), the Newcastle honesty box experiment where a photograph of eyes made people pay three times more, Justin Barrett's hyperactive agency detection, and Edward Titchener's 1898 experiment that tested the feeling directly - and found nothing. Your gaze detector isn't broken when it fires in an empty room. It's a smoke alarm. And smoke alarms are supposed to scream at burnt toast. You didn't inherit a paranoid brain. You inherited a social one.
