Anthropologist Robin Dunbar argued our brains can only juggle so many genuine relationships — a limit that shows up everywhere from villages to army units.
Dunbar's number, proposed by anthropologist Robin Dunbar, suggests humans can realistically maintain around 150 stable, meaningful social relationships at once, based on a correlation he found between primate brain size, particularly the neocortex, and typical social group sizes across primate species. Applied to humans, this predicted number lines up strikingly well with many historical and modern social groupings, from hunter-gatherer bands to military companies.
Numbers like 30 or 1,000 do not match Dunbar's proposal, 30 is far too small to reflect the layered circles of acquaintance his research described, while 1,000 vastly overshoots the limit he argued our brains evolved to handle.
Interestingly, Dunbar's broader model also describes smaller, nested circles within that number, roughly 5 very close intimates, 15 good friends, and 50 wider friends, suggesting our social world isn't just capped at 150 but structured in rings of closeness radiating outward from a tiny inner circle.
