In past posts, we have considered factors influencing ethics without much consideration of the structures that effect person’s responses to those behaviors. This post deals with one way of responding to another person or institutions behavior. Game theorist Robert Axelrod set up a competition to see what strategy would be most successful in an iterated prisoner’s dilemma game (remember the prisoner’s dilemma). Solutions were submitted by a large number of competitors with the object being to see who would be most successful. Two hundred rounds of the game were played with the winning strategy and surprisingly simple solution being Tit for Tat. The strategy was as follows:
In the first round, one player cooperated and after that did whatever the other player did the previous round. In other words, if the other player cooperated, player one cooperated. If player two defected, then player one responded in a like manner. What’s fascinating is that Tit for Tat never won a round. The best it ever did was a tie, but over two hundred iterations, it had the best score.
The features that make the game work is that it is “nice because the player using it never betrays first. It is provokable in that it quickly and reliably punishes the other player’s betrayal. It is forgivable because it can quickly return to cooperation even after defection and it is straightforward because it is simple enough that other players see that cooperation is the best choice.” ( Games People Play, The Teaching Company, 2008)
Whether this system is workable in all situations in real life is debatable but I think there are situations that it applies. Remember our discussion about putting children in timeout and parents saying that it didn’t work. The fact was that in most of those situations parents were inconsistent in carrying out of consequences and threats. In foreign relations we see that with dictators and demagogues it is difficult to deal with them if they see that when they push against other nations and those nations acquiesce to their pushing the belligerent nation pushes even more until either they get what they want or someone places serious sanctions against them. North Korea and Iran are current examples of this. And we saw this same response with Hitler in WWII. On the other hand, we have seen that Israel has taken a very aggressive posture towards aggression towards it and have used the Tit for Tat strategy very effectively. You attack us and we will immediately retaliate. On the other hand they have not always done a very good job with their own citizens as it pertains to illegal building of settlements on the West Bank.
For individual Christians who believe in forgiveness Tit for Tat may seem severe. We believe that everyone should be given another chance and that is as it should be. But we also know that in both the old and new testament there was the concept of consequences and even though forgiveness may flow out of a broken relationship, consequences still occur. So the question that I ask you, the reader, to consider and comment on are:
- How do you see Tit for Tat working or not working?
- What situations might you use Tit for Tat in your own relationships?
- What better ways might you engage persons that you feel have broken ethical covenant?

That was Robert Axelrod not Richard
Thanks for the correction. It’s been changed.
