In game theory, the word 'game' is used to describe any interdependence between interacting parties, and the Nash equilibrium is a prominent tool for analysing such interactions. I argue that the concept of the Nash equilibrium may also be used in non-gaming contexts. An individual is in a Nash equilibrium if his or her beliefs are consistent with his or her actions. Given that discordance between beliefs and behaviour is a typical cause of psychiatric disorders, individuals who are not in a Nash equilibrium are likely to be affected by such disorders. In this regard, the concept of the Nash equilibrium could aptly be introduced into the medical practitioner's vocabulary for describing a patient's mental health status.
在博弈论中，“游戏”一词被用来描述相互作用的各方之间的任何相互依存关系，纳什均衡是分析这种相互作用的重要工具。我认为，纳什均衡的概念也可以用于非博弈的情况。如果一个人的信仰与其行为一致，那么他就处于纳什均衡之中。鉴于信仰和行为之间的不一致是精神障碍的常见原因，因此处于纳什均衡之外的人很可能会受到这种障碍的影响。在这方面，纳什均衡的概念可以恰当地引入到医疗从业者的词汇中，用来描述患者的心理健康状况。
