> The nash equilibrium is actually for all players to defect. Only in games where players know the number of rounds (e.g. a suicide bomber defects because they’ve decided to cap the number of rounds they’re going to play). The same Wikipedia article describes that in studies where the number of rounds is unknown to players, superrational strategies are sustainable and that the “always defect” strategy becomes only one of several paths to Nash equilibrium.
