While philosophers have discussed the emotion of contempt from antiquity to the present day, contempt has received less attention in psychological research. We review the defining features of contempt, both as a short-term emotion and as a more long-lasting sentiment. Contempt is similar to anger in that it may occur after (repeated) social or moral transgressions, but it differs from anger in its appraisals, actions, and emotivational goals. Unlike anger, contempt arises when a person’s or group’s character is appraised as bad and unresponsive to change, leading to attempts to socially exclude the target. We discuss associative, self-regulatory, and social distancing functions of contempt and present a dynamic social model of contempt versus anger.
