Psychology of Disgust (And How Your Brain Makes GROSS Things Feel NORMAL)

Psychology of Disgust (And How Your Brain Makes GROSS Things Feel NORMAL) You'd kiss someone but refuse to share their toothbrush. You'd swim in a public pool but never drink a glass of its water. Why does your brain accept some disgusting things as perfectly normal? This video explores the psychology of disgust—and how familiarity, emotions, and learned associations shape what we consider clean, dirty, or disgusting. From Paul Rozin's famous cockroach experiment to surprising research on recycled water and human relationships, discover why feeling disgusted doesn't always mean something is dangerous, and why your brain's definition of normal isn't as logical as you think. What's something everyone else considers normal that you find absolutely disgusting?
