In other situations, though, lose-lose outcomes occur when win-win outcomes might have been possible. The classic example of this is called the prisoner's dilemma in which two prisoners must decide whether to confess to a crime. Neither prisoner knows what the other will do. The best outcome for prisoner A occurs if he/she confesses, while prisoner B keeps quiet. In this case, the prisoner who confesses and implicates the other is rewarded by being set free, and the other (who stayed quiet) receives the maximum sentence, as s/he didn't cooperate with the police, yet they have enough evidence to convict. (This is a win-lose outcome.) The same goes for prisoner B. But if both prisoners confess (trying to take advantage of their partner), they each serve the maximum sentence (a lose-lose outcome). If neither confesses, they both serve a reduced sentence (a win-win outcome, although the win is not as big as the one they would have received in the win-lose scenario).
