Cognitive dissonance is a psychological concept describing the mental discomfort experienced when an individual simultaneously holds two or more contradictory beliefs, ideas, or values, or when a belief conflicts with a behavior. As an academic concept and research area within social psychology, it investigates the resulting psychological tension and the motivational processes individuals employ to reduce this dissonance, often through changing beliefs, attitudes, or behaviors, or by rationalizing the inconsistency. Its significance lies in providing a framework for understanding fundamental aspects of human motivation, decision-making, and attitude change processes driven by the need for internal consistency.
