Prisoner's Dilemma


Prisoner's Dilemma

An illustration of game theory. Two prisoners are questioned separately for a crime. They are both told that if neither confesses, each will get a year in prison. If one confesses, there is a chance he will go free if the other does not, in which case the other gets three years in prison. If both confess, both get three years in prison. The prisoner's dilemma was originally formulated by mathematician Albert W. Tucker and has since become the classic example of a "non-zero sum" game in economics, political science, and evolutionary biology.
