Prisoner's dilemma


You and a randomly chosen co-player are matched for one round of the prisoner?s dilemma game. Each can opt either for cooperation or defection. If both choose to cooperate, both get 3 points each. If you both choose to defect, you get 1 point each. If you choose defect and the other cooperate, you receive 5 points and your co-player nothing. Conversely, if you cooperate and the other defects, you receive nothing and the co-player gets 5 points. Evaluations Number of players: 28 (14 games)
Frequency of payoffs:
Notes Comments The rational move is to defect (you get more, no matter what the other player decides to do). A majority chooses to cooperate, however.
