📖 เนื้อเรื่อง
Cognitive dissonance refers to the mental discomfort experienced when a person holds two or more contradictory beliefs, values, or attitudes. This discomfort often leads individuals to alter their beliefs or justify their behavior to reduce the inconsistency, rather than changing the behavior itself. The theory, proposed by Leon Festinger, suggests that people strive for internal consistency to maintain psychological harmony.

Professor: Let me give you a classic example. Imagine a student, Sarah, who strongly believes that cheating is morally wrong. Yet, during a difficult exam, she panics and copies answers from a classmate. Afterward, she feels intense discomfort. To reduce this dissonance, she doesn't admit her wrongdoing. Instead, she tells herself, 'The exam was unfair and the teacher made it too hard, so my action was justified.' By convincing herself that the situation was exceptional, she aligns her belief ('I am an honest person') with her action ('I cheated')—but only by changing her perception of the situation, not her actual behavior. This rationalization relieves her mental tension, allowing her to move on without changing her future study habits.
