The psychological state characterized by the presence of contradictory thoughts, beliefs, or attitudes within an individual. It occurs when there is an inconsistency or conflict between one's existing beliefs or attitudes and new information or experiences. This state of cognitive dissonance often creates a sense of discomfort or tension, prompting individuals to seek resolution by modifying their beliefs, attitudes, or behaviors to align with one another. The experience of cognitive dissonance can lead to a process of attitude change or decision-making as individuals strive to reduce the inconsistency and restore a sense of internal harmony.
