In Game Theory, the outcome of a cooperative strategy in the Prisoner's Dilemma will always lead to a better payoff for both players compared to pursuing self-interest.

In Game Theory, the Prisoner's Dilemma shows how two players can achieve a better outcome by cooperating rather than acting in their own self-interest. When both players choose to cooperate, they can both receive a higher payoff than if they each decide to betray the other. For example, imagine two friends who have stolen candy and can either confess or stay silent. If both stay silent, they both get a small punishment, but if one confesses while the other stays silent, the confessor goes free while the other gets a big punishment. Therefore, by working together and staying silent, they can minimize their punishment and achieve a better result than if they acted selfishly.
