Dilema dos prisioneiros na vida real

O dilema dos prisioneiros é uma situação clássica da teoria dos jogos. Nela, a decisão racional é de que os dois jogadores traiam um ao outro, embora a situação final de ambos fosse melhor se eles cooperassem. O vídeo abaixo, de um programa inglês de TV, mostra que a teoria funciona.



Da Wikipedia:

Two suspects are arrested by the police. The police have insufficient evidence for a conviction, and, having separated both prisoners, visit each of them to offer the same deal. If one testifies (defects from the other) for the prosecution against the other and the other remains silent (cooperates with the other), the betrayer goes free and the silent accomplice receives the full 10-year sentence. If both remain silent, both prisoners are sentenced to only six months in jail for a minor charge. If each betrays the other, each receives a five-year sentence. Each prisoner must choose to betray the other or to remain silent. Each one is assured that the other would not know about the betrayal before the end of the investigation. How should the prisoners act?
