Rationalization as a Defense: How It Works

Rationalization is a defence mechanism in which a convincing explanation makes one’s own behaviour, decision or feeling more acceptable while leaving an uncomfortable part of the experience unexamined. The person is not necessarily inventing an excuse deliberately: they may genuinely regard the reason as sufficient. Here we examine how that explanation reduces an inner conflict while getting in the way of a change in action.

“I work better under a deadline,” someone says after another overnight finish. The project was delivered, but a colleague had no time to check it, and the following day was lost to exhaustion. The question is specific: does the explanation account for the full cost of working this way?

A symbolic illustration about explanations and experience.

Imagine someone who wants to see themselves as reliable but has again put off a difficult task. Acknowledging “I was afraid to start and delayed it” is uncomfortable: shame and anxiety about being judged arise. Attention shifts from that conflict to the benefits of rushing: “But the last minute is when I really focus.” The explanation brings relief, and the need to reconsider preparation is postponed.

Next time, starting is delayed again. Rationalization sustains this particular loop: an action conflicts with the desired self-image → discomfort arises → a justification reduces tension → the pattern of action remains unchanged. When a mistake leads to self-attack through shame, it is especially important to distinguish responsibility for an action from the conclusion “there is something wrong with all of me.”

The fable of the fox and the grapes illustrates this movement through devaluing an unreachable goal: unable to reach the grapes, the fox declares them sour. An everyday version follows a job rejection: “I didn’t want to work there anyway.” Useful questions are what is actually known about the company, when the assessment changed and whether there is room for disappointment.

A work schedule really can be overloaded. The need for solitude can be genuine. Not wanting a relationship does not establish a hidden fear of intimacy. “I love my freedom” alone cannot reveal someone else’s motive.

A useful explanation can be checked against evidence and can account for consequences. “I was overloaded and didn’t reply. I should have let you know; next time I’ll say when I can return to the conversation” combines a reason with responsibility. “Everyone is busy; there was no reason to get upset” closes off the question of how the silence affected the other person.

Organising experience and finding meaning are not, by themselves, rationalization. This mechanism differs from intellectualization in its direction: abstract analysis creates distance from experience, while rationalization makes a particular action or decision easier to accept. The two approaches can occur in the same conversation.

“I was just telling the truth” leaves tone, insulting words and consequences outside the conversation. Disagreement on the substance does not disappear when someone acknowledges harshness: “I disagree with your decision, but the insult was unnecessary. I’m sorry for those words.” The disagreement still needs to be discussed afterwards.

The same applies to a pause in contact. People have a right to rest and distance; agreeing on when to return to a conversation helps the other person avoid being left in uncertainty. Self-observation should not turn a legitimate need into guilt.

In the online diary or a notebook, record one situation in four parts: what happened; how I explain it; what evidence supports the explanation and what it leaves out; what I feel and will do next. There is no need to reject your reason first or search for a single “true” motive. The aim is to broaden the picture enough to make a decision.

For example, someone cancels a medical appointment and explains it through work. They can then check: was another time genuinely unavailable, have they postponed before, and is there fear about the examination? If fear is present, it can be named. If money or scheduling is the issue, a different solution is needed. Whatever the findings, a journal entry cannot replace medical assessment of symptoms.

The next step should be an available action: finding another appointment, checking the cost or asking someone to come along. In the deadline example, it might mean starting with a short draft and allowing time for review. Changed action shows more than the harshest accusation of self-deception.

CBT SHIFT. Part 1 can be used to record a situation, a thought and a check of the evidence. CBT SHIFT. Part 2 provides a format for exploring beliefs that recur across situations. Self-Discovery Diary Course offers space for regular observations, while Emotion Diary provides a place to name feelings. Choose one tool for the task; this exercise does not require buying all of them. Other formats can be compared in the MriyaRun catalogue.

These materials do not identify a hidden motive on a person’s behalf or guarantee behaviour change. If writing becomes an endless search for what is “wrong” with you, shorten the practice and discuss the difficulties with a professional.

What in my explanation is supported? Which consequence am I leaving out? Can I acknowledge disappointment, fear or guilt without devaluing myself? Am I willing to revise the explanation if new evidence appears? What action is needed now, even if I do not yet understand all my motives?

Rationalization is worth exploring with curiosity about one’s own experience. Acknowledging “I had reasons, and I also caused inconvenience” leaves room both for circumstances and for repairing what is within my control.
