What it concludes

• The best strategy in the repeated prisoner's dilemma is Tit for Tat.
• Successful strategies share four qualities: nice, forgiving, retaliatory, and clear.
• Tit for Tat wins tournaments by cooperating first, retaliating immediately against defection, and immediately forgiving when the opponent returns to cooperation.
• Generous Tit for Tat improves performance in noisy environments by occasionally forgiving defections.
• Cooperation can emerge and thrive even among self-interested individuals when interactions are repeated.
