Prisoner’s dilemma

In game theory, the prisoner’s dilemma tells about two people who have the choice between cooperating and not cooperating. If they both cooperate, it will benefit both of them. However, if one wants to cooperate, and the other does not, it can create a terrible disadvantage for the one who wanted to cooperate. Therefore, risk-averse people will tend not to cooperate, even though it would have been in everyone’s interest to do so.
