If both players cooperate, they both receive the reward R for cooperating.
If both players defect, they both receive the punishment payoff P.
An extended "iterated" version of the game also exists, where the classic game is played repeatedly between the same prisoners, and consequently, both prisoners continuously have an opportunity to penalize the other for previous decisions.
If the number of times the game will be played is known to the players, then (by backward induction) two classically rational players will betray each other repeatedly, for the same reasons as the single-shot variant.
the only outcome from which each player could only do worse by unilaterally changing strategy).
The dilemma then is that mutual cooperation yields a better outcome than mutual defection but it is not the rational outcome because from a self-interested perspective, the choice to cooperate, at the individual level, is irrational.
The iterated prisoner's dilemma game is fundamental to some theories of human cooperation and trust.
On the assumption that the game can model transactions between two people requiring trust, cooperative behaviour in populations may be modeled by a multi-player, iterated, version of the game.
If both defect, then neither one gains or loses anything.They hope to get both sentenced to a year in prison on a lesser charge.Simultaneously, the prosecutors offer each prisoner a bargain.In reality, humans display a systemic bias towards cooperative behavior in this and similar games, much more so than predicted by simple models of "rational" self-interested action.A model based on a different kind of rationality, where people forecast how the game would be played if they formed coalitions and then maximized their forecasts, has been shown to make better predictions of the rate of cooperation in this and similar games, given only the payoffs of the game.
