This situation is called a prisoners’ dilemma because both sides are led to take an action that is against their mutual interest.* In the classic version of the prisoners’ dilemma, the police are separately interrogating two suspects. Each is given an incentive to be the first to confess and a much harsher sentence if he holds out while the other confesses. Thus each finds it advantageous to confess, though they would both do better if each kept quiet.
