Robin Ian MacDonald Dunbar (born 28 June 1947) is a British anthropology, evolutionary psychologist, and specialist in primatology behaviour. Dunbar is professor emeritus of evolutionary psychology 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
The son of an engineer, Dunbar was privately educated at Magdalen College School, Brackley.
He went on to study at the University of Oxford as an undergraduate student 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.
Career and Research
Dunbar spent two years as a freelance science writer.
[ Dunbar told BBC Radio interviewer Jim Al-Khalili in The Life Scientific in 2019 that he "got his first real job" only at the age of 40.][" The Life Scientific" interview, BBC Radio Four, 23 July 2019.]
Dunbar's career includes appointments at the University of Bristol, University of Cambridge from 1977 until 1982, and University College London from 1987 until 1994.
