Rationalization is a psychological defense mechanism where individuals justify their actions or feelings with logical reasons, even if these reasons are not the true motivations. This process helps reduce feelings of guilt or anxiety by providing a seemingly reasonable explanation for behavior that may be socially unacceptable or irrational. For example, a student who fails an exam might say, "I didn't study because the test was unfair," instead of acknowledging a lack of preparation. This allows the individual to maintain a positive self-image while avoiding the discomfort of facing their shortcomings. Rationalization can be seen in various contexts, including psychology, behavioral science, and everyday decision-making.
