Although many societies endorse objectivity in moral judgment and punishment, humans are frequently influenced by deep-rooted biases, such that superficially irrelevant factors can influence moral judgment and decision making. Hunger is a fundamental source of motivation and is known to redirect behavior in other domains. The present research aims to test whether hunger influences moral judgments and punishments. We first report results from four pilot studies (n = 1354) which, taken together, imply a positive relationship between self-reported hunger and harsher moral judgment. The main preregistered study then examined the effect of experimentally induced hunger on judicial sentencing and moral judgments. Hunger was manipulated by asking 246 undergraduates to not eat for at least four hours before the study. Participants in the Satiated condition received a snack before taking questionnaires, while those in the Hungry condition were given the same snack after responding to the questionnaires. Contrary to our pre-registered predictions, participants in the Hungry condition recommended significantly more lenient punishments, while the manipulation had no effect on moral judgment. Overall, the results suggest caution regarding previous findings indicating that hungry people punish more, and offer tentative evidence of the opposite effect under some conditions. We discuss possible reasons for the apparent inconsistencies between studies.

lut子惩罚？实验诱发的饥饿出乎意料地降低了建议处罚的严厉程度

尽管许多社会都认可道德判断和惩罚的客观性，但人类经常受到根深蒂固的偏见的影响，因此表面上无关的因素会影响道德判断和决策。饥饿是动机的基本来源，众所周知，它可以重定向其他领域的行为。本研究旨在检验饥饿是否影响道德判断和惩罚。我们首先报告了四个试点研究（n = 1354）的结果，这些研究加起来表明自我报告的饥饿与更严厉的道德判断之间存在正相关关系。预注册的主要研究然后研究了实验性饥饿对司法判刑和道德判断的影响。在研究开始之前，要求246名本科生至少四小时不吃东西，从而操纵了饥饿。满足条件的参与者在接受问卷调查之前先接受了零食，而饥饿状态的参与者则在回答问卷后给予了相同的点心。与我们预先登记的预测相反，处于饥饿状态的参与者建议宽大得多的惩罚，而操纵对道德判断没有影响。总的来说，这些结果表明人们对以前的发现保持谨慎，表明饥饿的人会受到更多的惩罚，并在某些情况下提供了相反效果的初步证据。我们讨论了研究之间明显不一致的可能原因。饥饿状态的参与者建议宽大得多的惩罚，而操纵对道德判断没有影响。总的来说，这些结果表明人们对以前的发现保持谨慎，表明饥饿的人会受到更多的惩罚，并在某些情况下提供了相反效果的初步证据。我们讨论了研究之间明显不一致的可能原因。饥饿状态的参与者建议宽大得多的惩罚，而操纵对道德判断没有影响。总的来说，这些结果表明人们对以前的发现保持谨慎，表明饥饿的人会受到更多的惩罚，并在某些情况下提供了相反效果的初步证据。我们讨论了研究之间明显不一致的可能原因。
