What is a facial expression?

Have you ever wondered if a smile means the exact same thing everywhere in the world? Or could a smile actually mean you're angry in a different country?! In this mind-bending episode of Philosophy is Not Boring, Mira and Finn explore the amazing science of faces! Travel back to 1967 with an American psychologist named Paul Ekman. He journeyed all the way to the highlands of Papua New Guinea to meet the isolated Fore people. His mission? To see if we all share the same basic facial expressions! By telling simple stories, Ekman discovered that people everywhere seemed to recognize the same six emotions: happiness, sadness, fear, disgust, anger, and surprise. He thought our brains were perfectly hardwired like a tablet! But wait, is it really that simple? Enter modern scientist Lisa Feldman Barrett! She argues that real feelings are much messier. Can you cry when you are super happy? Can you laugh when you are frustrated? Yes! Learn why your brain is actually a giant prediction machine, discover how to wiggle your ears, and find out why we must always ask questions instead of just guessing how someone feels!
