Practice question · Put in order
A Tit-for-Tat player faces a partner who defects on round 1 but cooperates on round 2. Order what Tit-for-Tat does across the interaction.
- Round 1: Tit-for-Tat cooperates (it is 'nice' and opens with cooperation).
- Round 3: Tit-for-Tat forgives and returns to cooperation.
- Round 2: Tit-for-Tat retaliates by defecting, mirroring the partner's last move.
- The partner defects on round 1.
- The partner cooperates on round 2.
Hints

Show the answer
- Round 1: Tit-for-Tat cooperates (it is 'nice' and opens with cooperation).
- The partner defects on round 1.
- Round 2: Tit-for-Tat retaliates by defecting, mirroring the partner's last move.
- The partner cooperates on round 2.
- Round 3: Tit-for-Tat forgives and returns to cooperation.
Why
Tit-for-Tat starts nice (cooperate), retaliates the round after a defection, and forgives as soon as the partner cooperates again. Being nice, retaliatory, and forgiving - in that behavioral order - is what made it win Axelrod's tournaments.
