Unformatted text preview: P r isoner Dilemma
PRI SONER B
This dilemma revolves around two prisoners, Tanya and Cinque, who have robbed H ibernia
Savings Bank and are now placed in separate isolation cells. The dilemma is constructed in
order to demonstrate why two people might not cooperate even if it is in both their best
i nterest. Both the prisoners care about their personal freedom. A prosecutor is makes an
offer to each:
1. If you confess and your partner remains silent, he will pay for the accused
charges and you will be set free. L ikewise, if your partner confesses and you
r emain silent, you will pay for the accused charges and he will be set free.
2. If you and your partner remain silent, both will be accused of possessions on
3. And, if you both confess, you both will spend the maximum time in prison.
Since each prisoner is concerned in maximizing his or her payoff, both shall betray each
other. The only concern of each prisoner is on how to minimize the t ime he or she spends in
p rison, without any concern for the other prisoner. And, since both care about their personal
f reedom, each prisoner will want to purse the best goal. This phenomenon is called ‘selfinterest’. I t’s this self-interest that will make both the prisoners’ confess. Nevertheless, the
p unishment that both will face when they both confess are worse than that when they face
i f both had remained silent. The table below is an interpretation of the above the puzzle.
