论文摘要

信任和信任度构成了持续的社会和经济互动的基础,它们也是合作,公平,诚实,甚至对于许多其他形式的亲社会和道德行为的基础。但是,信任需要风险,建立可信赖的声誉需要努力。那么,信任和信任度如何发展,在哪些条件下壮成长?为了找到答案,我们使用信托游戏的投资和受托人的投资回报作为两个关键参数,将信任和信托游戏运行。我们在不同的网络上研究此游戏,包括完整的网络,随机和无标度网络以及混合限制。我们表明,除一种情况外,网络结构对信任和可信度的演变几乎没有影响。具体来说,对于混合良好的人群,格子,随机和无标度网络,我们发现信任永远不会发展,而信任度则以某种概率演变,具体取决于游戏参数和更新动态。仅对于具有非归一化动力学的无标度网络,我们才能找到信任演变但可信度的参数值,以及信任和可信度不断发展的值。最后,我们讨论了可能导致信任演变的机制,并概述未来工作的方向。

Trust and trustworthiness form the basis for continued social and economic interactions, and they are also fundamental for cooperation, fairness, honesty, and indeed for many other forms of prosocial and moral behavior. However, trust entails risks, and building a trustworthy reputation requires effort. So how did trust and trustworthiness evolve, and under which conditions do they thrive? To find answers, we operationalize trust and trustworthiness using the trust game with the trustor's investment and the trustee's return of the investment as the two key parameters. We study this game on different networks, including the complete network, random and scale-free networks, and in the well-mixed limit. We show that in all but one case the network structure has little effect on the evolution of trust and trustworthiness. Specifically, for well-mixed populations, lattices, random and scale-free networks, we find that trust never evolves, while trustworthiness evolves with some probability depending on the game parameters and the updating dynamics. Only for the scale-free network with degree non-normalized dynamics, we find parameter values for which trust evolves but trustworthiness does not, as well as values for which both trust and trustworthiness evolve. We conclude with a discussion about mechanisms that could lead to the evolution of trust and outline directions for future work.
