Dunbar's number

Dunbar's number is a theoretical limit on the number of stable social relationships a person can maintain, estimated to be around 150. This concept, proposed by anthropologist Robin Dunbar, suggests that due to cognitive constraints, humans can effectively keep track of and have meaningful interactions with about 150 individuals, including friends, family, and acquaintances. Beyond this number, relationships tend to become less personal and more superficial. Dunbar's number helps explain social group sizes in communities, workplaces, and online networks, emphasizing the importance of close, meaningful connections within manageable social circles.
