Q218. Explicate and comment:
The result was another victory for TIT FOR TAT! The analysis of the data from these tournaments reveals four properties which tend to make a decision rule successful: avoidance of unnecessary conflict by cooperating as long as the other player does, provocability in the face of an uncalled for defection by the other, forgiveness after responding to a provocation, and clarity of behavior so that the other player can adapt to your pattern of action.
These results from the tournaments demonstrate that under suitable conditions, cooperation can indeed emerge in a world of egoists without central authority (Axelrod 1984: 184.5).
