当今社会中人民大众非常关注道德，关于道德的新闻、事件充斥着我们的日常生活，人们经常通过网络、媒体和自媒体的形式对他人的行为进行道德判断评价。在大众普遍参与的道德评判过程中，受到关注最多的是高社会阶层或低社会阶层行为者的行为。那么，人们会不会受到行为者本身社会阶层特征的影响，导致给予他们更宽松或更严厉的道德判断？为了发现并证实道德判断中社阶层效应的存在，本研究将通过研究一和研究二分别从道德行为和不道德行为两个方面探讨社会阶层特征对评判者进行道德判断的影响。 研究一主要是从道德行为方面出发，探索行为者的的社会阶层特征如何影响判断者对其行为的道德判断，及其内在机制与边界条件。研究一包括研究1、研究2和研究3。 研究1发现，被试对不同社会阶层行为者的道德行为进行判断时，存在道德判断的社会阶层效应。不管是通过整体的道德行为判断材料还是具体的关爱行为和公平行为情境想象，行为者社会阶层都会影响被试对其道德行为判断的严厉程度。同样的道德行为，相比低社会阶层行为者，被试对高社会阶层行为者的道德判断更宽松。 研究2从社会认可路径解释道德判断的社会阶层效应，在研究1的基础上，发现行为者的社会阶层通过社会认可的中介影响判断者对其道德行为判断。相比低社会阶层，被试对高社会阶层行为者有着更高的社会认可，更高的社会认可导致被试对高社会阶层做出的道德行为赞赏更高，道德判断标准更宽松。 研究3从判断者的角色角度出发，探索道德行为判断社会阶层效应的边界条件。研究发现，判断者角色是行为者社会阶层对判断者对其道德行为判断影响的边界条件。当被试是观察者时，行为者的社会阶层会影响被试的道德判断，使他们对高社会阶层比对低社会阶层的道德行为判断更宽松；而当被试是受益者时，道德行为判断的社会阶层效应消失。 研究二主要是从不道德行为方面出发，探索行为者的的社会阶层特征如何影响判断者对其不道德行为的道德判断，及其内在机制与边界条件。研究二同样包括三个研究，分别是研究4、研究5和研究6。 研究4发现，被试对不同社会阶层行为者的不道德行为进行判断时，存在道德判断的社会阶层效应。相比低社会阶层的不道德行为，被试认为高社会阶层行为者的不道德行为更加不道德，对他们的道德判断标准也更严厉。 研究5从愤怒路径解释不道德行为判断的社会阶层效应，在研究4的基础上，排除了社会期望和同情的中介路径，发现行为者的社会阶层通过愤怒的中介机制影响他人对其不道德行为判断。相比低社会阶层，被试对高社会阶层的不道德行为有着更高的愤怒，更高的愤怒导致被试认为高社会阶层做出的不道德行为更加不道德，对高社会阶层行为者的道德判断更严厉。 研究6从判断者的角色和不道德行为的不道德程度角度出发，探索不道德行为判断社会阶层效应的边界条件。发现判断者角色和不道德程度是行为者的社会阶层对判断者对其不道德行为道德判断影响的边界条件。当判断者角色是观察者时或行为的不道德程度一般时，存在道德判断的阶层效应，判断者对高社会阶层比对低社会阶层的不道德行为判断更严厉；而判断者角色是受害者时或行为的不道德程度严重时，不道德行为判断的社会阶层效应消失。 综上，行为者的社会阶层特征会影响判断者对其行为的道德判断。在道德行为上，判断者对高社会阶层比低社会阶层行为者的道德判断更宽松；在不道德行为上，判断者对高社会阶层比低社会阶层行为者的道德判断更严厉。

In today’s society, people are very concerned about morality. News and events about morality are full of our daily life. People often make moral judgment and evaluation on the behavior of others through the network, media and self-media. In the process of moral judgment in which the general public participates, the behavior of high-class or low-class actors is the most concerned. Then, will people be influenced by the social class characteristics of the actors themselves, leading to more lenient or stricter moral judgment? In order to discover and confirm the existence of social class effect in moral judgment, this research will discuss the influence of social class characteristics on the judges’ moral judgment from two aspects of moral behavior and immoral behavior through two studies respectively. The first part of research is mainly from the aspect of moral behavior, exploring how the social class characteristics of the actor affect the judge’s moral judgment of his behavior, as well as its internal mechanism and boundary conditions. The first study includes study 1, study 2 and study 3. Study 1 finds that there is social class effect in moral behavior judgment. Whether through the overall moral behavior judgment materials or specific caring behavior and fair behavior situational imagination, the social class characteristics of the actors will affect the severity of moral judgment on the moral behavior of the participants. For the same behavior, compared with the low-class actors, the participants had looser moral judgment on the moral behavior of the high-class actors. Study 2 explains the social class effect of moral judgment from the social acceptance path. Based on study 1, it is found that the social class characteristics of the actors influence the moral judgment of the judges on their moral behavior through the intermediary of social acceptance. Compared with the low-class actors, the participants have higher social acceptance for the high-class actors. Higher social acceptance leads to higher appreciation and looser moral judgment for the high-class actors. Study 3 explores the boundary conditions for judging the social class effect of moral behavior from the perspective of the judge’s role, and finds that the judge’s role is the boundary condition for the influence of the social class characteristics of the actor on the judge’s moral judgment of moral behavior. When the participants are observers, the social class characteristics of the actors will affect their moral judgment, making them more lenient to the moral behavior of the high-class actors than the low-class actors; However, when the participants are beneficiaries, moral behavior judges that the social class effect disappears. The second part is mainly to explore how the social class characteristics of the actor affect the judge’s moral judgment of his immoral behavior, and its internal mechanism and boundary conditions from the aspect of immoral behavior. The second study also includes three studies, namely study 4, study 5 and study 6. Study 4 finds that the social class effect of immoral behavior judgment, the imoral behavior of the high-class actors were more immoral and harsher than that of the low-class actors. Study5 explains the social class effect of immoral behavior judgment from the anger path. On the basis of study 4, it excludes the intermediary path of social expectation and sympathy, and finds that the social class characteristics of the actor influence others’ moral judgment of their immoral behavior through the intermediary mechanism of anger. Compared with the low-class actors, the participants have higher anger towards the immoral behaviors of the high-class actors. The higher anger leads the participants to think that the immoral behaviors of the high-class actors are more immoral, and the moral judgment to the high-class actors is more severe. Study 6 explores the boundary conditions for immoral behavior to judge the social class effect from the perspective of the role of judges and the immoral degree of immoral behavior. It is found that the judge’s role and immoral degree are the boundary conditions that the social class characteristics of the actor influence the judge’s moral judgment on his immoral behavior. When the judge’s role is observer or the immoral degree of behavior is general, there is a class effect of moral judgment. The judge is more severe in moral judgment of immoral behavior of the high-class actors than the low-class actors. However, when the judge’s role is the victim or when the immoral behavior is serious, the social class effect of immoral behavior judgment disappears. To sum up, the social class characteristics of the actor will affect the judge’s moral judgment of his behavior. In terms of moral behavior, the judges are more lenient in their moral judgment towards the high-class actors than those of the low-class actors. As for the immoral behavior, judges are more severe in their moral judgment of the high-class actors than those of the low-class actors.
