Cognitive Dissonance occurs when a person holds two or more contradictory beliefs, ideas, or values, or participates in an action that goes against one of these three, and experiences psychological stress because of that. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person’s belief clashing with new information perceived, wherein they try to find a way to resolve the contradiction to reduce their discomfort.
