…The prisoner’s dilemma focuses on the choice between cooperation and selfishness. Superficially it seems quite simple: You and another person have been caught by the police on suspicion of criminal activity and are being held in separate cells. The prosecutor visits each of you separately and offers a deal. If you confess and incriminate your accomplice while he or she remains silent, you will be convicted of a lesser crime, serving just one year in prison while your accomplice serves four. In the parlance of the game, you have “defected” from your friendship.
If you and your accomplice both refuse the deal and stay true to each other—remaining “cooperators” in the game’s lingo—you will both be convicted of a lesser crime and serve two-year sentences, since the police do not have enough evidence to convict either one of you of the more serious crime. If you both testify against each other—that is, if you mutually defect—then the police will convict both of you for the serious crime but give you only three years, since you provided some evidence.
Clearly, the best choice for you as an individual is to defect. You get only one year in prison if you rat on your accomplice and he doesn’t rat on you. Even if you both rat on each other, the penalty is three years, not the maximum sentence. It is only the sucker who doesn’t defect while his accomplice does who spends four years in the slammer, the maximum sentence. On the other hand, both prisoners are worse off when they turn on each other than they would be if they both kept silent.
Nowak was fascinated by the prisoner’s dilemma because it provides a mathematical way to study human behavior and, more broadly, the evolutionary costs and benefits of cooperation. Each round of the game generates numbers (the number of years in prison can be considered points), there can be different results based upon different strategies, and all of this can be turned into calculations. With the prisoner’s dilemma, Sigmund said, one could use math to examine the thorniest conundrum of our social lives: how to weigh personal gain against the common good.
For the rest of the alpine weekend and all the way back to Vienna, Nowak talked to Sigmund about the game. He visited him the following day at his office at the Institute for Mathematics in Vienna, which shared a building with a seminary, the priests on the first floor and the mathematicians on the second. “It was total tranquility,” says Nowak, a Roman Catholic who holds fast to his faith. “In biochemistry, we were always breaking things, and there were bad smells. But here there were just empty corridors with someone occasionally walking by, deep in thought. I was amazed that someone could make a living just by thinking.”
In 1987 Nowak decided to do doctoral work with Sigmund on the mathematics of evolution. Their focus was the prisoner’s dilemma and its endless iterations, now parsed with computers and math.
Others had already studied cooperation using the prisoner’s dilemma, notably political scientist Robert Axelrod, who held virtual tournaments in the 1970s. Scientists around the world sent Axelrod strategies for the “prisoners”—instructions for when they would cooperate and when they would defect—to wield in round after computerized round. Each round, the strategies received points; the shorter the prison term, the higher the score.
Over the course of hundreds of computerized rounds, the winning strategy was one called Tit for Tat: Whatever you did in the last round of the game, I will do to you in this round. This strategy relies on direct reciprocity and abounds in the real world, especially in communities where creatures have a history with one another. For instance, Neighbor Jones is more likely to change a flat tire for Neighbor Newell if Newell helped fix Jones’s broken lawn mower last week. It holds true in the animal world as well: A vampire bat is more likely to share a blood meal with others in the cave if those others shared a blood meal with it the last time it failed to find prey…Read More
