The prisoner's dilemma is a standard example of a game analyzed in game theory that shows why two completely rational individuals might not cooperate, even if it appears that it is in their best interest to do so. The preferred outcome for both players (both cooperating) is not an equilibrium because each has an incentive to defect, leading to a worse outcome for both.
