Lindenberg et al. report experimental evidence for the effect of hedonic shifts on subjects’ propensity to engage in moral hypocrisy. Hedonic shifts are changes in individuals’ cognitive states that can be triggered by cues in these individuals’ environments such as ambient smells. Individuals in a hedonic cognitive state aim at doing what makes them feel good. Hence, the authors hypothesize that (1) individuals who are in a bad mood and are put in a hedonic cognitive state will more often take a moral stance and (2) when asked to act morally refuse to do so, (3) especially when the costs for acting morally are high, and (4) even if the moral issue upon which they are asked to act is unrelated to the issue pertaining to the moral stance they took. The authors test these four hypotheses in two laboratory experiments and conclude that their results support these hypotheses. In this comment, I highlight design, measurement, and data analysis issues arising with the two studies that challenge this conclusion. Throughout my comment, I give some indications as to how a laboratory experiment testing these four hypotheses could be designed and conducted.

没有证据表明享乐转变会带来更多的道德虚伪：对林登伯格等人的评论。(2018)

林登伯格等人。报告关于享乐转变对受试者从事道德虚伪倾向的影响的实验证据。享乐转变是个体认知状态的变化，可以由这些个体环境中的线索（例如环境气味）触发。处于享乐认知状态的个体旨在做让他们感觉良好的事情。因此，作者假设 (1) 心情不好并处于享乐认知状态的人会更经常采取道德立场，以及 (2) 当被要求按照道德行事时拒绝这样做，(3) 特别是当道德行为的成本很高，并且（4）即使要求他们采取行动的道德问题与他们所采取的道德立场相关的问题无关。作者在两个实验室实验中测试了这四个假设，并得出结论，他们的结果支持这些假设。在这篇评论中，我强调了挑战这一结论的两项研究中出现的设计、测量和数据分析问题。在我的评论中，我就如何设计和实施检验这四个假设的实验室实验给出了一些指示。
