N人信任博弈及其复制者动态

The N-Player Trust Game and its Replicator Dynamics

Hussein Abbass, Garrison Greenwood, Eleni Petraki

摘要:

信任是一个基本概念,它支撑着社会系统的一致性和弹性,并塑造人类行为。尽管信任作为一个社会和心理学概念的重要性,但这个概念并没有得到进化博弈理论家的太多关注。介绍了一个N人信任社会困境博弈模型。虽然该理论表明,从长远来看,一个没有不值得信赖的个人的社会将为整个社会和个人带来最大的财富,但进化动力学表明,只有在初始种群中没有不值得信赖的个人的特殊情况下,才会达到这种理想状态。当初始种群中包含哪怕是最小数量的不值得信任的个体时,社会就会收敛为零信任者,并有许多不值得信任的个体。信任的促进是一项艰巨的任务,尽管事实上,信任者和值得信赖的受托人的组合是最理性和最佳的社会状态。本文介绍了复制动力学的博弈和结果,希望进化博弈的研究人员在填补这一关键空白的文献中看到机会。

英文摘要:

Trust is a fundamental concept that underpins the coherence and resilience of social systems and shapes human behavior. Despite the importance of trust as a social and psychological concept, the concept has not gained much attention from evolutionary game theorists. In this paper, an N-player trust-based social dilemma game is introduced. While the theory shows that a society with no untrustworthy individuals would yield maximum wealth to both the society as a whole and the individuals in the long run, evolutionary dynamics show this ideal situation is reached only in a special case when the initial population contains no untrustworthy individuals. When the initial population consists of even the slightest number of untrustworthy individuals, the society converges to zero trusters, with many untrustworthy individuals. The promotion of trust is an uneasy task, despite the fact that a combination of trusters and trustworthy trustees is the most rational and optimal social state. This paper presents the game and results of replicator dynamics in a hope that researchers in evolutionary games see opportunities in filling this critical gap in the literature.
