Cognitive dissonance
Explanation:
Cognitive dissonance was proposed by Leon Fe-stinger. Cognitive dissonance is related to conflicts between belief, attitude, and behavior of a person. This process produces mental discomfort in a person. If a person is not satisfied create discomfort in person related to their belief, attitude, and behavior.
