Robin Dunbar
Robin Ian MacDonald Dunbar (born 28 June 1947) is a British anthropologist and evolutionary psychologist and a specialist in primate behaviour. He is currently head of the Social and Evolutionary Neuroscience Research Group in the Department of Experimental Psychology at the University of Oxford. He is best known for formulating Dunbar's number, a measurement of the "cognitive limit to the number of individuals with whom any one person can maintain stable relationships". Education Dunbar, the son of an engineer, was educated at Magdalen College School, Brackley. He went on to study at Magdalen College, Oxford, where his teachers included Niko Tinbergen; he completed his Bachelor of Arts in Psychology and Philosophy in 1969. Dunbar then went on to the Department of Psychology of the University of Bristol and completed his PhD in 1974 on the social organisation of the gelada, ''Theropithecus gelada'', a monkey that is a close relative to baboons. He spent two years as a freela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunbar's Number
Dunbar's number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships—relationships in which an individual knows who each person is and how each person relates to every other person. This number was first proposed in the 1990s by British anthropologist Robin Dunbar, who found a correlation between primate brain size and average social group size. By using the average human brain size and extrapolating from the results of primates, he proposed that humans can comfortably maintain 150 stable relationships. There is some evidence that brain structure predicts the number of friends one has, though causality remains to be seen. Dunbar explained it informally as "the number of people you would not feel embarrassed about joining uninvited for a drink if you happened to bump into them in a bar." Dunbar theorised that "this limit is a direct function of relative neocortex size, and that this, in turn, limits group size ..the limit ...
