Cognitive Evolution Based on Subjective Learning Promotes Cooperation in Public Goods Game

In order to alleviate the cognitive bias and cooperation dilemma caused by the supremacy of interests among players in the game, we take the subjective game as the research framework, propose two strategies updating models based on subjective cognition from the perspective of information fusion and emotion regulation, and study the cognitive evolution of participants in the public goods game. Through the simulation experiment on the NetLogo platform, we find that, for the decision-making process of information processing, the participants pay more attention to the long-term reputation value, which can avoid cognitive bias to some extent, and then improve the cooperation dilemma of the system through the reputation effect; For the internal emotion regulation process, individuals stick to their accumulated emotional value and improve their emotional sensitivity, which can make them have a strong resistance to the invasion of the betrayer. Our research, to a certain extent, inhibited the free riding behavior in the multi-player game situation, and maintained a high level of cooperation between groups. The strategy updating model proposed in our research provides a new way to study the cognitive evolution of players in the game process from the perspective of modeling and simulation, and has certain practical significance to help solve the problem of group cooperation dilemma.
