Tit-for-tat strategy can never do better than its opponent because ________.

Question

Quizplus · Accepted Answer

The tit-for-tat strategy is to start by cooperating and then to mirror the opponent's previous move. This means that if the opponent cooperates, tit-for-tat will cooperate as well, and if the opponent defects, tit-for-tat will defect in the next round. Therefore, tit-for-tat will always respond to the opponent's previous move rather than making the first move. If the opponent always cooperates, tit-for-tat will do well by cooperating back, resulting in mutual cooperation. If the opponent always defects, tit-for-tat will also defect in every round, resulting in mutual defection. In any case, tit-for-tat will never do better than its opponent, but it can achieve the best possible outcome given the opponent's move.
