cognitive consistency theory

Cognitive consistency theory suggests that people prefer their beliefs, attitudes, and behaviors to align smoothly. When there’s a conflict—such as knowing smoking is unhealthy but still smoking—this discomfort motivates them to change either their beliefs or actions to restore harmony. Essentially, we strive for mental harmony by reducing inconsistencies, which helps us feel more comfortable and confident in our decisions and self-image. This drive for consistency influences many of our thoughts and actions, often leading us to justify or rationalize our choices to avoid internal tension.
