Final answer:
Contempt is caused by a violation of communal norms or ethical standards, differing from disgust, which deals with revulsion, and anger, which is a reaction to injustice.
Step-by-step explanation:
According to Paul Rozin and colleagues (1999), contempt is elicited by a violation of community standards, social hierarchies, or ethics.
This emotion can arise when we perceive someone as being beneath us or as violating a moral or social expectation, which distinguishes it from other negative emotions such as disgust and anger. Disgust typically is a reaction to physical or moral revulsion, whereas anger is often a response to perceived harm or injustice.
