Dunbar’s number. Named after a British anthropologist named Robin Dunbar. He studied primate brains, and their behavior in groups. And he found something that will change the way you think about the world. He found that the larger the primate’s neocortex, the larger the communities it formed. It takes a lot of brain to process all of the relationships in a complex society, you see. When primates find themselves in groups larger than what their brains can handle, the system breaks down. Factions form. Wars break out.
