TIT-FOR-TAT (ohgod)

Consider the following: two well-intentioned people adopt the TFT strategy for deciding whether to be cooperative with each other. All goes well for a while, but then one of these unintended slights occurs. Person A believes that Person B “defected” on her (whether defection here means intentionally revealing a secret, skimming profits, not working hard enough, etc.), when in actuality Person B’s behavior was accidental (i.e., she didn’t intend to act in an untrustworthy manner). Assuming they both adhere to TFT, the death spiral begins. While tit-for-tat can recover from defections when used against many strategies, this isn’t the case when it’s used against itself. The result is that noise in the system can doom what otherwise appeared to be the superior strategy; diz DeSteno.
