Explaining social limits with drawings from @itsmarceliina

The creator explains the concept of Dunbar's number, starting with a hook about the cognitive limit of human relationships. She details its origin from anthropologist Robin Dunbar's study of primate brain sizes and social groups, explaining the role of the neocortex. The creator then applies this theory to humans to arrive at the number 150 and illustrates the broader concept as a series of concentric circles representing different layers of social connection, from close friends to strangers.

Transcript excerpt

No matter how many people you meet in life, there's a limit to how many meaningful relationships you can actually maintain and it all comes down to one number. This is part three of uncovering the hidden patterns that explain how the world works. Today, we're learning about Dunbar's number. When Oxford anthropologist Robin Dunbar came up with this number, he wasn't studying human friendship. He was actually studying why some primates live in larger social groups than others and found that the group size was closely related to neocortex ratio, the size of the brain's outer layer relative to the rest of it. The idea was that larger groups require more mental worse, keeping track of who's who, who's allied with who, and who you can trust. So Dunbar asked if that relationship held for humans, how large should our social groups be? Plugging the human neocortex ratio into his primate regression, he found that number to be about 150. But Dunbar's number is actually a series of numbers which together describe a structured hierarchy of relationships within your social world. The central number tier represents the outer layer of people you can maintain a meaningful social relationship with.
