Why You can't have more than 5 REAL friends (The Dunbar Effect )

Right now, your phone says you have hundreds of friends. Maybe thousands. But the real answer to how many people you can actually know is far stranger, and it was settled long before the first phone ever existed. In this video, you'll discover why your brain has a built-in social ceiling, how Oxford anthropologist Robin Dunbar found it by studying primates, and why the same layered pattern of 5, 15, 50, and 150 shows up in hunter-gatherer bands, villages, companies, and even your Christmas card list. You'll see why social media expanded your follower count but never your inner circle, what a 2021 study from Swedish researchers says about whether the number is truly exact, and what Jeffrey Hall's research reveals about how many hours it really takes to make a close friend. Most importantly, you'll learn why your oldest instincts are asking you to spend your time on the handful of people who count.
