Variation in behaviour promotes cooperation in the Prisoner's Dilemma game.

Nature - 15 Apr 2004

McNamara John M, Barta Zoltan, Houston Alasdair I

Abstract excerpt

The Prisoner's Dilemma game is widely used to investigate how cooperation between unrelated individuals can evolve by natural selection. In this game, each player can either 'cooperate' (invest in a common good) or 'defect' (exploit the other's investment). If the opponent cooperates, you get R i...
