Generosity Always Rewards

This is the title of the article published in the American scientific magazine. Stewart and Plotking, from the biology department at the University of Pennsylvania, believe that in the long run the only tactics that cause a positive response are those based on generosity. This research calls to mind the "Prisoner's Dilemma," a game from the 1950's. In the game, two prisoners who cannot communicate with one another have to choose whether to confess their crime (thus betraying the other), or to deny it (cooperating with the other). By cooperating, the prison sentence will be shorter. Flipping the Darwinian concept of survival of the fittest on its head, Stewart said, “We find that in evolution, a population that encourages cooperation does well. To maintain cooperation over the long term, it is best to be generous.”
