Você não é frio. Seu cérebro só tem 150 vagas — e estão quase todas ocupadas.

You have hundreds of followers, maybe thousands of contacts — but how many of those people do you really know? There's an invisible limit within your brain that decides who gets in and who stays out of your real relationships. That limit has a name: Dunbar's Number. In this video, you'll discover why your brain is designed to maintain exactly 150 stable social relationships, what happens when that limit is exceeded, and why social media has never been able to change that — no matter how many followers you have. 📌 Based on research by anthropologist Robin Dunbar, University of Oxford. ────────────────────────── 🔔 Subscribe and turn on notifications so you don't miss the next video. 👍 If this video made you think, leave a like — it really helps the channel. 💬 Write in the comments: how many people do you believe are part of your 150? ────────────────────────── #UnfilteredMind #Psychology #DunbarNumber #HumanBehavior #BrainScience #SocialMedia #Friendship #Neuroscience
