Rationalization is a defense mechanism (ego defense) in which apparent logical reasons are given to justify behavior that is motivated by unconscious instinctual impulses. It is an attempt to find reasons for behaviors, especially one's own. Rationalizations are used to defend against feelings of guilt, maintain self-respect, and protect oneself from criticism. Rationalization happens in two steps: A decision, action, judgement is made for a given reason, or no (known) reason at all. A rationalization is performed, constructing a seemingly good or logical reason, as an attempt to justify the act after the fact (for oneself or others). 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 unconscious (e.g. to create a block against internal feelings of guilt or shame). People rationalize for various reasons—sometimes when we think we know ourselves better than we do. Rationalization may differentiate the original deterministic explanation of the behavior or feeling in question. Many conclusions individuals come to do not fall under the definition of rationalization as the term is denoted above.

DSM definition According to the DSM-IV, rationalization occurs "when the individual deals with emotional conflict or internal or external stressors by concealing the true motivations for their own thoughts, actions, or feelings through the elaboration of reassuring or self serving but incorrect explanations". Examples Individual Rationalization can be used to avoid admitting disappointment: "I didn't get the job that I applied for, but I really didn't want it in the first place." Egregious rationalizations intended to deflect blame can also take the form of ad hominem attacks or DARVO. Some rationalizations take the form of a comparison. Commonly, this is done to lessen the perception of an action's negative effects, to justify an action, or to excuse culpability: "At least [what occurred] is not as bad as [a worse
