History I / Political Organization
Practice question · Multiple choice

A band of thirty foragers has no chief; a neighbouring chiefdom of two thousand does. Why does political centralisation track group size so closely?

Hints
  1. Count the pairs of people in a group of 30 and in one of 2,000.
  2. What must happen to a dispute once everyone cannot be in one conversation?
Show the answer

D. Because face-to-face consensus stops scaling past a few dozen

Why

The number of relationships grows roughly as the square of the group, so consensus fails long before the group feels large. Centralisation answers that arithmetic.
