Village in Your Brain ebook

In a world of Facebook friends and Instagram followers, we feel more connected than ever. Yet, loneliness is at an all-time high. The British anthropologist Robin Dunbar proposed a biological explanation for this paradox: the human brain has a hard cognitive limit on the number of stable social relationships it can maintain. That number is approximately 150. "The Village in Your Brain" explains the science behind "Dunbar's Number." It traces our social evolution from primate grooming circles to hunter-gatherer tribes, showing that our neocortex was designed for village life, not global connectivity. When we try to maintain thousands of weak ties online, we exhaust our emotional bandwidth and neglect the deep, supportive bonds we actually need for survival. This book is a call to declutter your social life. It categorizes relationships into layers—from the "support clique" of 5 people to the "sympathy group" of 15—and provides a framework for aligning your digital habits with your biological reality. It challenges the quantity-over-quality mindset of the social media age.
