How to Encourage Cooperation
Political Scientist Robert Axelrod
asked game theory experts to submit computer programs designed to prevail in game providing rewards  either  for refusing to cooperate  or  for cooperating when the programs encountered other programs
 
TIT  FOR  TAT
1 st  encounter with any program,  Tit for Tat cooperates   2d encounter:  Tit for Tat  did what the other program did on previous encounter
Tit for Tat never gets repeatedly victimized & never gets locked into mutually costly chains of mutual betrayal
Simple conditional cooperation is more infectious than unmitigated meanness
if tit for tat had been  tossed into the game  with 49 steadfast  non-cooperators,  there would have been a 49-way tie for first place Robert Wright, The Moral Animal
Most of Tit for Tat’s neighbors were designed to cooperate under at least  some  circumstances
We are designed to cooperate under at least some circumstances
When volunteers playing the Prisoner’s Dilemma Game  cooperated with one another, the “reward circuits” of their brains were  activated, the same regions that are activated when certain drugs are taken or when good fortune befalls us Emory University Professor Gregory Berns .
How Do You Play Tit for Tat? Cooperate  Retaliate for Betrayal Forgive  Return to Cooperation
