The prisoner's dilemma is a game theory thought experiment involving two rational agents, each of whom can either cooperate for mutual benefit or betray their partner ("defect") for individual gain. The dilemma arises from the fact that while defecting is rational for each agent, cooperation yields a higher payoff for each.
Both players defecting (mutual defection (MD)) results in lower payoffs to each player than both player cooperating (mutual cooperation (MC)). So, while going from the stable equilibrium of MD to MC would be a Pareto improvement, in single-shot Prisoner's dilemma rational economic players fail to achieve the efficiency of mutual cooperation.
Subjective expected relative similarity (SERS) is a normative and descriptive theory that predicts and explains cooperation levels in a family of games termed Similarity Sensitive Games (SSG), among them the well-known Prisoner's Dilemma game (PD). [1]
A Nash equilibrium of this prisoner's dilemma game is the situation in which both players pick "defect", denote it (,). That strategy pair yields a payoff of 10 to the row player and 10 to the column player, and no player has a unilateral incentive to switch their strategy to maximize their own payoff.
The Prisoner's Dilemma game is another well-known example of a non-cooperative game. The game involves two players, or defendants, who are kept in separate rooms and thus are unable to communicate.

To avoid the worst-case outcome of the prisoner’s dilemma, though, the company has hedged its bets. It seeks out fellow corporate climate leaders and sells them on its new CO2-light products.

In iterated prisoner's dilemma strategy competitions, grim trigger performs poorly even without noise, and adding signal errors makes it even worse. Its ability to threaten permanent defection gives it a theoretically effective way to sustain trust, but because of its unforgiving nature and the inability to communicate this threat in advance ...
