Are people self-serving when moralizing personality traits? Past research has used cross sectional methods incapable of establishing causality, but the present research used experimental methods to test this. Indeed, two experiments ( = 669) show that people self-servingly inflate the moral value of randomly assigned personality traits they believe they possess, and even judge other people who share those same traits as more moral, warm, and competent than those who do not. We explain various methodological challenges overcome in conducting this research, and discuss implications for both psychology and philosophy.

道德品质评价中的自私偏见

人们在道德化人格特质时是否自私？过去的研究使用了无法建立因果关系的横截面方法，但目前的研究使用了实验方法来检验这一点。事实上，两个实验 (= 669) 表明，人们会自私地夸大他们认为自己拥有的随机分配的人格特质的道德价值，甚至判断其他具有相同特质的人比那些拥有相同特质的人更有道德、更热情、更有能力。不是。我们解释了在进行这项研究时克服的各种方法论挑战，并讨论了对心理学和哲学的影响。
