Robin Dunbar, a British anthropologist, developed Dunbar's number in the 1990s after discovering a relationship between the average size of a social group and the brain size of primates. The suggested cognitive limit for the number of people with whom someone can maintain a stable social relationship is 150. Exceeding this number is extremely rare, because becoming close to new people causes the quality of some older relationships to deteriorate over time
