Figure 6: Asymptotic behaviour of the simulation model.
From: Resilient cooperators stabilize long-run cooperation in the finitely repeated Prisoner’s Dilemma

(a) Cooperation by game for rounds 8, 9 and 10 for the simulation with 40% resilient cooperators. The timescale is 4,000 games, ten times the length of our experiment, suggesting that the stabilization of unravelling observed in Fig. 5b is permanent. (b) Asymptotic average round of first defection r∞ versus fraction of resilient coooperators α, averaged over 10 sets of simulations. The single point shows the values (α, r∞) obtained from our experiment.
