People vary in how they perceive, think about, and respond to moral issues. Clearly, we cannot fully understand the psychology of morality without accounting for individual differences in moral functioning. But decades of neglect of and explicit skepticism toward such individual differences has resulted in a lack of integration between moral psychology and personality psychology—the study of psychological differences between people. In recent years, these barriers to progress have started to break down. This special issue aims to celebrate and further increase the visibility of the personality psychology of morality. Here, we introduce the articles in this special issue by highlighting some important contributions a personality-based perspective has to offer moral psychology—particularly in comparison to the currently prominent social psychological approach. We show that personality psychology is well-placed to (a) contribute toward a rigorous empirical foundation for moral psychology, (b) tackle the conceptualization and assessment of stable moral tendencies, (c) assess the predictive validity of moral traits in relation to consequential outcomes, (d) uncover the mechanisms underlying individual differences in moral judgments and behavior, and (e) provide insights into moral development. For these reasons, we believe that moral psychology needs personality psychology to reach its full scholarly potential.

为什么道德心理学需要人格心理学

人们对道德问题的感知、思考和反应的方式各不相同。显然，如果不考虑道德功能的个体差异，我们就无法完全理解道德心理学。但几十年来对这种个体差异的忽视和明确的怀疑导致道德心理学和人格心理学（研究人与人之间的心理差异）之间缺乏整合。近年来，这些进步的障碍已开始被打破。本期特刊旨在颂扬并进一步提高道德人格心理学的知名度。在这里，我们通过强调基于人格的观点必须为道德心理学提供的一些重要贡献来介绍本期特刊中的文章，特别是与当前流行的社会心理学方法相比。我们表明，人格心理学非常适合（a）为道德心理学提供严格的实证基础，（b）解决稳定道德倾向的概念化和评估，（c）评估与后果相关的道德特征的预测有效性。结果，(d) 揭示道德判断和行为中个体差异的机制，(e) 提供对道德发展的见解。出于这些原因，我们认为道德心理学需要人格心理学才能充分发挥其学术潜力。
