The Prisoner's Dilemma

       THE PRISONER'S DILEMMA

The prisoner's dilemma is a paradox in decision analysis in which two individuals acting in their own self-interests do not produce the optimal outcome. The typical prisoner's dilemma is set up in such a way that both parties choose to protect themselves at the expense of the other participant. As a result, both participants find themselves in a worse state than if they had cooperated with each other in the decision-making process. The prisoner's dilemma is one of the most well-known concepts in modern game theory . In this classic game theory experiment, you must decide: rat out another for personal benefit, or cooperate? It is best explained by taking the example of two prisoners( let them be A and B) who are being investigated in two separate cells . The policemen do not have substantial evidence against them ( this information is not known to the prisoners ) and both of them are offered certain incentives to testify against their partner . In this situation each has two options and their fates depend upon the choices made by the other person. 

The Prisoner's Dilemma is widely used in fields like Psychology , Business , Economics, Computer Science and is an exemplary example of human behaviour and loyalty under pressure.
