Human behaviour: Punisher pays
Manfred Milinski1 & Bettina Rockenbach2
Abstract
The tendency of humans to punish perceived free-loaders, even at a cost to themselves, is an evolutionary puzzle: punishers perish, and those who benefit the most are those who have never punished at all.
Humans are champions of cooperation. Reciprocity — the idea that, if I help you this time, you'll help me next time1 — is a secret of our success.
