The process of creating excuses to justify behaviors is known as:

Rationalization is the process of creating excuses or justifications for behaviors, thoughts, or feelings that may otherwise be deemed unacceptable. This defense mechanism allows individuals to preserve their self-esteem and maintain a positive self-image by framing their actions in a more acceptable light. For instance, someone who procrastinates on an important task might tell themselves that they work better under pressure, thereby rationalizing their behavior instead of confronting the underlying reasons for their procrastination.

In the context of lifespan developmental psychology, understanding rationalization helps illuminate how individuals cope with conflicts and make sense of their choices across different stages of life. Recognizing this defense mechanism can also provide insight into patterns of behavior that may repeat in various contexts, contributing to an understanding of growth and change over time.
