Why Your Brain Can Only Handle 150 Friends

Your phone says you have 1,200 friends. But if something went wrong at 3 in the morning, how many would you actually call? That gap isn't a flaw in you. It's a limit built into your skull over millions of years. In this video, you'll discover why your brain evolved to manage only about 150 relationships, and why the number gets stranger the closer you look. You'll meet the anthropologist Robin Dunbar and his social brain hypothesis, learn why gossip was ancient infrastructure, and see why your closest circle holds only about five people. You'll also find out what happened when researchers tested whether social media could break the limit, and what actually keeps a friendship alive. If this made you look at your own friendships differently, like the video, leave a comment telling us who your five are, and subscribe for more stories about what your ancient brain is still doing today. #DunbarsNumber #DunbarNumber #SocialBrainHypothesis #RobinDunbar #HumanEvolution #Anthropology #Psychology #HumanBehavior #EvolutionaryPsychology #Friendship #Loneliness #SocialMedia #HumanHistory #BrainScience #EducationalVideo #Doodle #Explainer #WhyYouDoThis #AncientHumans #Neuroscience
