Dunbar’s number has been popularized as the supposed cognitive limit to the number of individuals with whom any one person can maintain stable social relationships: the kind of relationships that go with knowing who each person is and how each person relates socially to every other person.[1] Proponents assert that group sizes larger than this generally require more restricted rules, laws, and enforced policies and regulations to maintain a stable cohesion.

Dunbar’s number was first proposed by British anthropologist Robin Dunbar, who theorized that “this limit is a direct function of relative neocortex size, and that this in turn limits group size … the limit imposed by neocortical processing capacity is simply on the number of individuals with whom a stable inter-personal relationship can be maintained.” On the periphery, the number 150 also includes past colleagues such as high school friends with whom a person would want to reacquaint themselves if they met again.[2]
