"The Village Brain – Why you can only love 150 people at a time" examines the cognitive limit known as "Dunbar's Number." Evolutionary anthropologist Robin Dunbar theorized that the human neocortex can only maintain stable social relationships with about 150 people. This book contrasts our biological hardwiring, evolved for small tribes, with the modern reality of thousands of social media "friends." Science writer Monica Hart explains the stress and anxiety caused by exceeding this limit. She argues that the feeling of social burnout is a natural reaction to trying to maintain emotional bonds with a population size our brains were not designed to handle. The book breaks down the layers of friendship (inner circle vs. acquaintances) and how digital platforms flatten these nuances. "The Village Brain" is a call to prune your social network. It validates the need for a smaller circle and explains why deep connection requires a limit on quantity. It is a guide to aligning your social life with your biology.
