David McRaney Quote
Once people started coming up with ways to maintain larger groups, like armies, cities, and nations, humans started subdividing those groups. Dunbar’s number explains why big groups are made of smaller, more manageable groups like companies, platoons, and squads—or branches, divisions, departments, and committees. No human institution can efficiently function above 150 members without hierarchies, ranks, roles, and divisions.
