FIGURE 20-1 Prisoner's Dilemma This payoff matrix illustrates the prisoner's dilemma. If the prisoners could agree not to confess, each would get a light sentence. But each prisoner is offered the chance to go free if he confesses to the crime and agrees to serve as a witness against the other prisoner. With this incentive, both will likely confess and each will be sentenced to 5 years in jail. B Confesses B Does not confess Prisoner A: 5 years A Confesses A Does not confess Prisoner B: 5 years Prisoner A: 10 years Prisoner A: Goes free Prisoner B: 10 years Prisoner A: 6 months Prisoner B: Goes free Prisoner B: 6 months
