厌恶是一种强大的人类情感，直到最近才被研究。目前的理论并没有连贯地解释厌恶的目的，也没有解释为什么广泛的刺激会引起类似的情绪反应。超过4万人使用照片刺激完成了一项基于网络的调查。据报道，具有潜在疾病威胁的物体的图像比很少或没有疾病相关性的类似图像明显更令人厌恶。在世界所有区域都发现了这种反应模式。女性的厌恶敏感度高于男性；在整个生命过程中，厌恶敏感度不断下降；陌生人的体液比近亲的更恶心。这些数据提供了证据，证明人类的厌恶情绪可能是对环境中代表传染病威胁的物体的进化反应。
Disgust is a powerful human emotion that has been little studied until recently. Current theories do not coherently explain the purpose of disgust, nor why a wide range of stimuli can provoke a similar emotional response. Over 40 000 individuals completed a web-based survey using photo stimuli. Images of objects holding a potential disease threat were reported as significantly more disgusting than similar images with little or no disease relevance. This pattern of response was found across all regions of the world. Females reported higher disgust sensitivity than males; there was a constant decline in disgust sensitivity over the life course; and the bodily fluids of strangers were found more disgusting than those of close relatives. These data provide evidence that the human disgust emotion may be an evolved response to objects in the environment that represent threats of infectious disease.
