Prisoner’s dilemma

The prisoner's dilemma is a situation where two people who committed a crime are being interrogated in separate rooms, giving them two choices on how to act, creating three possible outcomes. We'll call the prisoners Prisoner A and Prisoner B.

• If Prisoner A keeps his mouth shut and doesn't say anything, but Prisoner B spills his guts, Prisoner A will get the worst punishment, while Prisoner B will walk free.
• Symmetrically, if Prisoner A speaks up but Prisoner B stays silent, Prisoner A walks free and B is severely punished.
• If both Prisoner A and Prisoner B confess both get punished, but to a lesser degree.
• Lastly, if both keep their mouths shut, the police will not be able to convict either, forcing both to receive the least punishment for a different, unrelated crime.

Chicken Dilemma

The game of chicken, also known as the hawk-dove game or snowdrift game, is a model of conflict for two players in game theory.

Chicken is a famous game where two people drive on a collision course straight towards each other. Whoever swerves is considered a 'chicken' and loses, but if nobody swerves, they will both crash. So the payoff matrix looks something like this:

                  B swerves               B straight

A swerves            tie               A loses, B wins

A straight     B loses, A wins            both lose
