The title says it all. The game introduced in chapter 12 of this book is probably one of the easiest games I've ever played. Dawkins himself says that "it is so simple that I have known clever men misunderstand it completely, thinking that there must be more to it." (page 203)
This books explains it with a banker who pays out winning to the two players. "Suppose that I am playing against you. There are only two cards in each of our hands, labelled COOPERATE, and DEFECT. to play we each choose one of our cards and lay it face down on the table. Face down so that neither of us be influenced by the other's move: in effect, we move simultaneously. We now wait in suspense for to turn the cards over.The suspense is because our winnings depend not just on which card we have played (which we each know). but on the other player's card too (which we don't know until the banker reveals it). (page 203)
The cards that are played with are 2 by 2, meaning that there are four outcomes.
"Outcome I: We both played cooperate. The banker pays each of us $300. This is respectable sum is called the Reward for the mutual cooperation.
Outcome II: We have both played defect. The banker fines each of us $10. This called the Punishment for mutual defection.
Outcome III You have played cooperate; I have played defect. That banker pays me $500 (the Temptation to defect) and fines you (the Sucker) $100.
Outcome IV: You have played defect; I have played cooperate. The banker pays you the temptation payoff of $500 and fines me, the Sucker, $100." (page 203)
The whole idea of a dilemma starts when both of players play the defect card. From that second, one of the platers suffers the penalty for mutual defection. If one of them would have cooperated, the Sucker's payoff, either way would have been worse. No matter which way you can go, DEFFECT will always have the best outcome. The 'prisoner' comes from an imaginary example, which two men are in jail. What happens through out this games depends on what each on them do, and neither of the prisoners know what crime they have committed. The payoffs in this case, of course are "not in dollars, but in jail sentences... Both players know that whatever their opponent does, they themselves cannot do better than defect., yet both also know that if only both had cooperated, each one would have don better. If only... if only... if only there would be some way of reaching an agreement" (page 205-206) to make things easier.
After reading the whole introduction of this, we started to play this game. We changed the payoffs into our own grading system, and started to play against each other. Seeing as we switched the payoff to our grading system, it was pretty obvious that the results of this game were going to have an impact on our grade. We saw how the suckers suffered, and how the temptation of defect, really does benefit all. We analyzed this game and realized how it is valid for social interactions. Today, we live in a very competitive society. The only thing that people want in the world is success, and they will do whatever takes to get there. Some will cheat, and some will cooperate. There will be cases when those who cheat (play the defect card) and up winning, and seeing how thing are, they win most of the time. It's very rare to see others cooperate for their own benefit. They just think about themselves, why would they care about those who might get in the way, right? When we played this game in class, we see how people would start of cooperating, but as soon as the game was about to end, people played their defect card, and the player being played against, almost felt like they were being stabbed in the back. Maybe the whole idea of the defect card being the most beneficial outcome is to prove how selfish people can actually be.
