Magical numbers

Some interesting thoughts on group's anthropology

  1. Edward Hall’s “Beyond Culture,” "Fortunately, something is known both empirically and scientifically about the influence exerted by size on groups and the effect of size on how the groups perform. Research with business groups, athletic teams, and even armies around the world has revealed there is an ideal size for a working group. This ideal size is between eight and twelve individuals. This is natural, because man evolved as a primate while living in small groups…Eight to 12 persons can know each other well enough to maximize their talents. In groups beyond this size, the possible combinations of communication between individuals get too complex to handle; people are lumped into categories and begin the process of ceasing to exist as individuals. Tasks than can’t be handled by a group of eight to 12 are probably too complex and should be broken down further. Participation and commitment fall off in larger groups — mobility suffers; leadership doesn’t develop naturally but is manipulative and political."
