Dunbar’s number” is a theoretical cognitive limit on the number of stable social relationships humans can maintain at one time. According to Robin Dunbar, a British anthropologist, humans have the cognitive capacity to keep track of somewhere around 150 close personal connections. Beyond this limited circle, we start treating people less like individuals and more like objects, and groups of people beyond this limit are likely to splinter off into subgroups over time.
