Question

Quizplus · Accepted Answer

The self-interest of players in a prisoners' dilemma game typically leads to a less than optimal outcome for both. Each player's incentive is to defect and betray the other, which results in both players getting a worse outcome than if they had cooperated. This is known as a Nash equilibrium, where neither player has an incentive to change their strategy unilaterally, even though both would benefit if they cooperated.
