Disgust is an emotional response of revulsion to something considered offensive, distasteful, or unpleasant. Disgust is experienced primarily in relation to the sense of taste and secondarily to anything which causes a similar feeling by sense of smell, touch, or vision. The emotion of Disgust can be described to serve as an affective mechanism following occurrences of negative social value, provoking repulsion, and desire for social distance.
Feelings of Disgust, through rousing social distance, may lead to dehumanization. Therefore, a person or group that is generally connected with disgusting effects and seen as physically unclean may induce moral avoidance. Being deemed disgusting produces a variety of cognitive effects that result in exclusion from the perceived inner group.
