Rationalization (making Excuses)
In psychology and logic, rationalization (also known as making excuses) is an unconscious defense mechanism in which perceived controversial behaviors or feelings are logically justified and explained in a rational or logical manner in order to avoid any true explanation, and are made consciously tolerable – or even admirable and superior – by plausible means. Rationalization encourages irrational or unacceptable behavior, motives, or feelings and often involves ad hoc hypothesizing. This process ranges from fully conscious (e.g. to present an external defense against ridicule from others) to mostly subconscious (e.g. to create a block against internal feelings of guilt).
People rationalize for various reasons. Rationalization may differentiate the original deterministic explanation of the behavior or feeling in question. Sometimes rationalization occurs when we think we know ourselves better than we do. It is also an informal fallacy of reasoning.
