Dunbar’s Number


The primatologist Robin Dunbar observed through study that the number of individuals a primate can get to know and trust closely is related to the size of its neocortex. Extrapolating from his study of primates, Dunbar theorized that the Dunbar number for a human being is somewhere in the 100–250 range, which is supported by certain studies of human behavior and social networks. - Shane Parrish Managing: “A suggested cognitive limit to the number of people with whom one can maintain stable social relationships..with a commonly used value of 150.” - Gabriel Weinberg
