+This paper observes that generative agent behaviours in game experiments align
+with observed human subjects’ behaviours. The reasoning analysis reveals that
+the decision to cooperate in the final round of in the iterated prisoner’s
+dilemma game is influenced by the misconception that one’s defection might lead
+to simultaneous defection from the other player.
