用通俗的话来说，道德上的违法行为“在嘴里留下了不好的味道。“这个比喻暗示了道德厌恶和与毒性和疾病有关的更原始形式的厌恶之间的联系，但这种关系仍然缺乏令人信服的证据。我们直接测试了道德厌恶的原始口腔起源，通过寻找由味觉厌恶（由不愉快的味道引起）、基本厌恶（由污染物的照片引起）和道德厌恶（由经济游戏中的不公平待遇引起）引起的面部运动活动的相似性。我们发现，所有这三种状态都引起了面部提唇肌区域的激活，这是口鼻排斥反应的特征。这些结果表明，不道德行为与疾病媒介和不良品味一样，会引发厌恶感。
In common parlance, moral transgressions "leave a bad taste in the mouth." This metaphor implies a link between moral disgust and more primitive forms of disgust related to toxicity and disease, yet convincing evidence for this relationship is still lacking. We tested directly the primitive oral origins of moral disgust by searching for similarity in the facial motor activity evoked by gustatory distaste (elicited by unpleasant tastes), basic disgust (elicited by photographs of contaminants), and moral disgust (elicited by unfair treatment in an economic game). We found that all three states evoked activation of the levator labii muscle region of the face, characteristic of an oral-nasal rejection response. These results suggest that immorality elicits the same disgust as disease vectors and bad tastes.
