Book detail: How Many Friends Does One Person Need? Dunbar’s Number and Other Evolutionary Quirks is presented as a focused source page for quotations connected with this book, collection, transcript, or source record.
This work examines Dunbar's number, the theoretical cognitive limit of approximately 150 stable social relationships that humans can maintain, proposed by evolutionary anthropologist Robin Dunbar. The book investigates how this constraint emerges from brain size and social complexity in primates, and extends to various aspects of human social organization including personal networks, community structures, and organizational behavior. The text also addresses additional evolutionary patterns in human sociality, drawing connections between our ancestral past and contemporary social challenges. The author applies principles from evolutionary psychology and behavioral ecology to illuminate why human social systems take particular forms and why certain social configurations feel more natural or sustainable than others.
