Since the influential work of Schelling, binary choice games with externalities (situations in which the consequences of the choices of an agent are affected by the actions of other agents) have become central within social dilemma literature. Previous literature has developed models with agents mainly based on classic probability theory where populations formed by impulsive agents (i.e., they tend to switch strategies even when the difference between payoffs is extremely small) are one of the most common case. However, recent theoretical and empirical findings have showed how the recurrent contextual effects observed in psychology studies are better predicted by the probability theory employed in quantum physics. In this paper, we study the dynamics in binary choices when introducing quantum cognition in the Schelling model, distinguishing between context-insensitive agents (compatible choices in the quantum framework) and context sensitive agents (incompatible choices). We observed that: (i) in the context insensitive model, quantum agents population dynamics can be interpreted as a particular case of the impulsive agents population; (ii) the context-sensitive quantum population dynamics cannot be replicated by a context-insensitive population; (iii) assuming all things being equal, the future choice of the context-sensitive quantum agents is unpredictable. These results suggest that the quantum framework can be seen as an ideal tool to improve the modeling attempt of binary choice with externalities.

具有量子决策的二元选择动力学

自从谢林(Schelling)的有影响力的工作以来,具有外部性的二元选择游戏(一种行为者的选择的后果受其他行为者的行为影响的情况)已成为社会困境文献的中心。以前的文献已经开发了主要基于经典概率理论的代理模型,其中由冲动代理形成的总体(即,即使收益之间的差异非常小,它们也倾向于切换策略)是最常见的情况之一。但是,最近的理论和经验发现表明,通过量子物理学中使用的概率理论,可以更好地预测心理学研究中观察到的反复情境效应。在本文中,我们将在Schelling模型中引入量子认知时研究二元选择的动力学,区分上下文不相关的代理(量子框架中的兼容选择)和上下文不相关的代理(不兼容的选择)。我们观察到:(i)在上下文不敏感模型中,量子代理种群动态可以解释为脉冲代理种群的特殊情况;(ii)上下文无关的种群无法复制上下文敏感的量子种群动力学;(iii)假设所有条件都相同,则上下文敏感量子试剂的未来选择是不可预测的。这些结果表明,量子框架可以被视为一种理想的工具,可以改善带有外部性的二元选择的建模尝试。(i)在上下文不敏感的模型中,量子代理种群动态可以解释为脉冲代理种群的特殊情况;(ii)上下文无关的种群无法复制上下文敏感的量子种群动力学;(iii)假设所有条件都相同,则上下文敏感量子试剂的未来选择是不可预测的。这些结果表明,量子框架可以被视为一种理想的工具,可以改善带有外部性的二元选择的建模尝试。(i)在上下文不敏感的模型中,量子代理种群动态可以解释为脉冲代理种群的特殊情况;(ii)上下文无关的种群无法复制上下文敏感的量子种群动力学;(iii)假设所有条件都相同,则上下文敏感量子试剂的未来选择是不可预测的。这些结果表明,量子框架可以被视为一种理想的工具,可以改善带有外部性的二元选择的建模尝试。上下文敏感量子试剂的未来选择是不可预测的。这些结果表明,量子框架可以被视为一种理想的工具,可以改善带有外部性的二元选择的建模尝试。上下文敏感量子试剂的未来选择是不可预测的。这些结果表明,量子框架可以被视为一种理想的工具,可以改善带有外部性的二元选择的建模尝试。
