The Prisoner's Dilemma: A Game Theory Classic

TLDRThe prisoner's dilemma is a game that illustrates why rational players may not cooperate even if it seems in their best interest. It involves two players, Walter and Jesse, who are faced with a choice between confessing or remaining silent. Regardless of their decisions, it results in a Nash equilibrium where both players confess and receive longer sentences.
