Case Study: The Prisoner Dilemma Match.

Let's say you're playing a prisoner's dilemma with a "suspect" who is locked up in another room. Moreover, imagine that this game is not played once, but many times. The final score you get for your game is the total number of years you have been imprisoned.

You want to make that score as little as possible. What strategy should you use? Should you start by confessing or keeping silent?

How will the actions of another participant affect your confessional decisions later on?

The prisoner dilemma is a complex game. To encourage cooperation, participants should punish each other for uncooperative behavior. But the previously described strategy of Jack and Jill's water cartel – that as long as the other defaults, one party defaults forever – is not forgiven.

In a game that has been repeated many times, it may be more desirable to allow participants to return to the outcome of the cooperation after a period of non-cooperation.

To illustrate which strategy is best, political scientist Robert? Robert Axelrod played a match. People enter the game through a computer program designed to repeatedly play the prisoner's dilemma.

Each program in which the game is played corresponds to all the others. The one who gets the procedure with the fewest total years in prison is the "winner".

The winner results in a simple strategy known as a pay-for-one. According to the report-for-report, participants should start with cooperation, and then do what the other participant did the last time. Therefore, the participants must cooperate until the other party breaches the contract; He defaulted until the other party re-cooperated.

In other words, the strategy starts with friendship, punishes unfriendly participants, and, if the other person changes, gives forgiveness. To Axelrod's surprise, this simple strategy is better than all the more complex strategies that people lose.
