You know that relationship is hurting you. You know that job is wearing you down. And every time someone points it out, you find yourself explaining to yourself why, deep down, it's not that bad.
The cognitive dissonance is the tension we feel when two of our beliefs contradict each other, or when what we do doesn't match what we believe. It's an unpleasant feeling, and the mind works actively to make it disappear.
Festinger's theory
Leon Festinger, in 1957, defined cognitive dissonance as the state of discomfort that arises when inconsistent ideas, beliefs, or behaviors coexist.
The discomfort grows the more the conflict concerns aspects important to the person: it's not very bothersome to discover an inconsistency on a marginal topic, much more so when it touches one's own values or self-image.
The originating experiment
In 1959, Festinger and Carlsmith conducted an experiment that has become a classic, and it's instructive because the result is the opposite of what one would expect.
Participants were made to perform a deliberately boring task. Then they were asked to tell the next participant that it had been interesting. Some were offered twenty dollars, others just one.
Those who had received just one dollar later declared that they had found the task more enjoyable. Those who had received twenty did not.
The explanation: those who had been paid well had an external justification — I lied for the money — and no tension to resolve. Those who had received one dollar did not, and in order not to think they had lied for nothing, they changed their own opinion. Unable to change the behavior, they changed the belief.
How the tension is resolved
There are three paths, and only one is the one we would want.
Change the behavior. The healthiest and most difficult: stop doing the thing that contradicts what we believe.
Change the belief. "After all, it's not that harmful." It costs little and works immediately, which is why it's the most used.
Add elements that reduce the contrast. "I work too much, but I'm building something." "He treats me badly, but he had a difficult childhood." The contradiction remains, but it's softened.
There's a fourth path, very frequent: avoiding the information that creates dissonance. Not talking about that thing, changing the subject, pushing away those who bring it up.
The Fox and the Grapes
Aesop's fable is the best-known representation of the mechanism: what cannot be obtained gets devalued. "It probably wasn't good anyway" doesn't describe the grapes, it describes how the fox protects itself from frustration.
Where we encounter it
In relationships that don't work. It's one of the most powerful drivers in maintaining a harmful bond. The more time, energy, and sacrifices you've invested, the more unsustainable it becomes to think it was all for nothing — so the mind reassesses the relationship upward. This is the reason why, paradoxically, the more one has suffered, the harder it becomes to leave. I often see this in the emotional dependency.
In manipulative relationships. Those who suffer gaslighting experience continuous dissonance between what they perceive and what they're told. Resolving it by siding with themselves means acknowledging they're in a harmful relationship; resolving it by siding with the other person is easier — and that's exactly what the mechanism leverages.
In addictions. "I can quit whenever I want" is cognitive dissonance in pure form. It applies to substances as well as to work: I talk about it regarding the workaholism.
In health. Knowing that something is harmful and continuing to do it produces tension, which is often resolved by downplaying the risk rather than the behavior.
In important choices. After an irreversible decision, we tend to reassess the chosen option more favorably and devalue the discarded one. It's not that we were right: it's that we need to have been right.
Why this mechanism exists
It's not a flaw. It serves to maintain a coherent sense of self, which is a condition for functioning: living while feeling in permanent contradiction would be unsustainable.
The problem is that coherence can be achieved in two ways — by changing what one does, or by changing what one thinks — and the second costs much less. So, systematically, we take the shortcut.
Recognizing it in yourself
A few practical signals.
- You find yourself defending a situation that, if a friend told you about it, you would immediately judge
- You have very elaborate explanations for something simple
- You get irritated when someone touches on that topic, more than the situation warrants
- You avoid talking about that subject with people who know you well
- You often use "yes, but"
- You feel relieved when someone agrees with you, more than convinced
Irritation, in particular, is a useful indicator: a disproportionate reaction signals that someone has touched a point where tension already exists.
What can be done
Noticing the justification while you're making it. There's no need to dismantle it: just noticing it is enough. "I'm explaining again because it's fine this way."
The friend's criterion. If a friend told you exactly this situation, what would you think? Distance makes visible what cannot be seen from within.
Ignoring what you have already invested. The years spent are not an argument for staying: they are spent regardless. The only useful question concerns the future, not the past.
Don't avoid those who contradict you. The temptation to push away those who mention the problem is strong, and it's often the first step of isolation.
Tolerating contradiction without resolving it immediately. Staying for a while in "this doesn't add up for me", without rushing to fix it, is uncomfortable but it's the only way not to close it off in the easiest way.
Frequently Asked Questions
Is it a disorder?
No. It's a normal and universal mechanism, not a pathology.
Can it be eliminated?
No, and that's a good thing. You can learn to recognize when we're resolving it in the most comfortable way instead of the most honest way.
What relationship does it have with denial?
They are close but distinct. In denial, the information is excluded from consciousness. In dissonance, the information is present and gets reinterpreted to make it compatible.
Why do people defend those who treat them badly?
Because admitting to being treated badly implies admitting that you stayed, and this produces very strong tension. Justifying the other person is, in the moment, less painful than acknowledging one's own situation.
A journey in Florence or online
If you recognize yourself in the mechanism of justifying a situation that part of you knows to be harmful, you can contact me for an initial introductory session. I receive in my office in Florence, at Via Tommaso Campanella 5, in the Campo di Marte – Coverciano area, and online.
You'll also find repetition compulsion and halo effect.
