Why Do Narcissists Lie So Much?

Why do narcissists lie? “Because they can”…as the cliché goes. Seriously, many narcissists do lie and they lie constantly.

They lie about their education, they lie about their achievements, and they lie about extramarital affairs or what they had for dinner.

If someone else is boasting about their 2019 Mercedes, a narcissist will claim (s)he has a 2020 Mercedes just to make her/himself appear superior.

Narcissists may lie for various reasons, including seeking admiration or hiding their flaws or mistakes. They commonly lie to seek attention.

In some cases, a person with this type of personality disorder will lie to make the person (s)he is lying to question their own sense of reality.

The Narcissist and Lying

There’s a difference between lying, and being a liar. Most people tell small lies at some point.

We do this for many different reasons, for example:

• For our own benefit: “The fish I caught was three feet long!” (it wasn’t)
• To get out of trouble: “No officer I have no idea why you pulled me over” (you do)
• To make others feel good “I love your new haircut!” (you don’t)

These are the classic “little white lies” that people tell. They are seen as harmless, for the most part, and a natural part of navigating the social landscape.

But then there are the bigger lies, those that give us an unfair advantage, often at someone else’s expense. Some researchers call these “black lies”.

These are less accepted as part of normal human life. 

One study in 2014 found that narcissistic traits predicted the use of both white and black lies – but was more successful in predicting black lies.

So while narcissists may engage in the same white lies that everyone else does, there’s another layer of lies on top of that, the black lies, that they are also prone to. 

It’s these black lies that separate a liar from someone who lies.

And it’s the type of black lies, and the motivations behind them, that separate a liar from a narcissistic liar.

Narcissists lie for specific reasons related to the condition of NPD. So to understand what a narcissistic liar is, we need to delve into their motivations for lying in the first place.

Why Do Narcissists Lie?

From one perspective, a narcissist’s whole life is a lie. Their huge ego and apparent high self-esteem hides a weaker, fragile self underneath.

Their actions are designed to be consistent with this projected self, and to protect it at all costs. 

And because narcissists have difficulty generating self-worth from within, they need to get it from the reactions of other people. So they lie.

They lie about their skills, their abilities, and their accomplishments.

Their goal is to receive flattery, praise, attention and adoration from others to prop up their self-esteem (known as “narcissistic supply”).

Several studies have confirmed this. In one study from 2014, the researchers looked into the motivations for lying among people who possess one of the “dark triad” of personality traits – narcissism, Machiavellianism, and psychopathy.

They found that narcissists lied for self-gain. Specifically, their lies revolved around popularity, dominance, and appearance themes.

Reading Suggestion: Do Narcissists Enjoy Kissing?

In another study, 100 Facebook users were given tests of narcissistic personality traits, and also self-esteem.

Then, their Facebook pages were independently analyzed to see how much “self-promotional content” they contained (content aimed at presenting themselves positively to others).

They found that higher levels of narcissism and lower levels of self-esteem predicted more self-promotional content.

These studies demonstrate the general pattern behind narcissists’ lies – the goal here is to get that adoration, that narcissistic supply, from other people, to build up their self-esteem.

However, as many victims of narcissistic abuse will attest, this is not the only type of lie that comes out of a narcissist’s mouth.

The Narcissist Lies to Control You

Control is very important to the narcissistic liar. Again, this comes from the need for narcissistic supply.

They need to be in control to put themselves at the top of the social totem poll.

Lies help them control what people think about them and how people act around them.

Once they’ve achieved this sort of control, the narcissist has the upper hand, and they have free reign to please themselves. They can indulge in their desires at will.

For example, a narcissistic husband may engage in adultery, and then lie about who they have been with

If you start to press the matter, the lies may evolve to gaslighting.

This is where the narcissist makes you question your own perceptions, your own memories of what has happened

At this point, your questioning your own sanity.

Now you’re in a bad position – once you’ve been gaslit, you rely on the narcissist to sort the supposed truth from the lies – and they are the one delivering both.

This sort of deliberate, calculated lying is more common in people with malignant narcissism, which is sort of a cross between narcissism and psychopathy.

Malignant narcissists display little to no empathy, and they often lie and abuse not just to gain control, but because they enjoy it.

Does a Narcissist Believe Their Own Lies?

This really depends on the type of lie that they tell.

In July 2020, Donald Trump bragged in a Fox News interview about a “very hard” cognitive test that he apparently “aced.”

The test, it turned out, was the Montreal Cognitive Assessment, a test of cognitive decline.

A high score doesn’t mean you’re mentally superior, it just means you don’t suffer from a major dysfunction in faculties like memory and attention.

It’s the sort of test where they take away your driving license if you don’t get 100%.

So Trump’s brag was a clear lie. But his thought process probably wasn’t “I will lie about the test and make people believe I am superior.”

Most likely, the thought process was something like “Since I am such a stable genius, the test must have been a very hard test.” 

When it comes to self-aggrandising lies – the sort of lie that lines up with how narcissists like to see themselves – they probably do believe them.

It would be very hard for them to believe otherwise, because that would mean catching a glimpse of their true self-worth – something narcissists strive to avoid.

But it’s a different story regarding the more deliberately manipulative kind of lies we just discussed.

In these cases, the narcissist likely knows they are lying and is doing so consciously.

A 2018 study at Ariel University in Israel found a connection between narcissistic personality traits and how people say they lie.

They also found that, not only do narcissists admit to lying more, they believe they are better at lying than other people (and there may be some truth to that – practice makes perfect after all).

So this study suggests that narcissists do tell some lies that they know to be lies – lies that they don’t actually believe themselves.

Is the Narcissist a Pathological Liar?

If you have a narcissist in your life who is constantly lying, whether to boost their own ego or to manipulate you, you might wonder, do narcissists lie all the time?

Is the narcissist a pathological liar?

The answer is probably not. Pathological liars, generally speaking, lie compulsively.

When they see an opportunity to lie, they cannot resist it.

There’s some evidence suggesting this comes down to abnormalities in the brain, perhaps liked to certain personality disorders, head injuries, or hormone imbalances. 

Think of it like this – in any conversation, the brain is churning away in the background, coming up with things you might say next.

Many of these possible responses will be lies. Still, in most people, there is a filter blocking the lies – except in certain circumstances (the white lies we talked about earlier, or perhaps black lies on occasion, in moments of weakness, or to avoid shame or punishment).

Pathological liars lack this filter, so the lies just come pouring out.

There’s no strategy, no rhyme, and no reason. They just can’t stop them.

With narcissists, as we’ve seen, there is usually a reason for the lies – and sometimes even a deliberate manipulative strategy.

So while narcissists lie frequently, the narcissistic liar is not a pathological liar, in the strictest sense.

But if that is indeed the case – if there is a reason for the lies, do narcissists ever feel bad about lying?

Can a Narcissist Feel Remorse About Their Lies?

The boring answer here is, “it depends.” 

Think of remorse as social glue that helps keep people together.

When you start doing something negative towards someone else, remorse kicks in, you feel bad, discouraging you from doing something like that in the future.

This helps you avoid alienating people so that you’ll enjoy better relationships with the people around you.

So, to feel remorseful about something you did, you have to understand the consequences of your actions on other people.

That requires empathy – the ability to feel what others feel in a given situation. 

Unfortunately, many narcissists display low levels of empathy. In these cases, they don’t feel bad for hurting others.

The remorse “circuitry” might well be present in the narcissist’s brain, but without empathy, it doesn’t get triggered.

Now, not all narcissists are low in empathy, and even in those that are, “low” does not mean “zero.”

So it’s likely that narcissists do feel some remorse at some times. B

ut this may not be enough to trigger a shift in how they behave towards you. For more information on this topic, see my related article: Can a Narcissist Truly Apologise.

How to Deal With a Narcissist Who Lies?

So we’ve gone over the “what” and the “why” of narcissistic lies, now let’s talk about how you can deal with them.

The first and perhaps most important step, is to get a good picture of the relationship with the narcissist.

As we’ve talked about, it can be hard to separate fact from fiction when dealing with narcissists, especially the high-functioning variety. 

Do you find yourself questioning your senses, memories, and perceptions?

Do you have an underlying feeling that something isn’t “right” in the relationship, feelings that they can talk you out of?

If so, you may be deep into a web of lies. It can help to get a second opinion, from someone who doesn’t know the narcissist or a counselor who specializes in NPD.

This can give you a grounding in reality, as someone looking in from the outside may see things very clearly that you can’t.

Even if you’re already sure you’re being lied to, it can still help to seek outside support, which can give you more emotional strength.

Next, try to evaluate the situation carefully. Lies and manipulation are a form of emotional abuse, and they are not something you should feel you need to accept.

If you are being abused in this way, it is time to think about leaving the narcissist.

Wait a second, just leave? Shouldn’t you consider confronting them about their behavior?

Should You Confront a Narcissist About Their Lying?

Because some narcissists have a way of getting you “under their spell”, so to speak, you may hold strong, and genuine affection towards them, even despite their abusive behaviour.

So you might hold out hope,

Unfortunately, this outcome is quite unlikely. Confronting a narcissist will often lead to more of the same behavior that you’re trying to avoid.

Remember, narcissists, are good at lying, and probably very good at lying to you. Once you start a confrontation, you’re in their world.

This will not be the first time they’ve been caught lying, and, quite possibly, they’ve had some practice at getting out of this situation.

Rebecca Zung has a nice post breaking down what often happens when a narcissist gets caught lying, which she breaks into the Four D’s:

• Denial: they may simply deny that they lied, or deny that your version of events is the truth (potentially leading to gaslighting).

• Deflection: with narcissists, there’s always someone else to blame, and they may even see their actions as justified – “I only do it because I love you!”. 

• Devalue: in a fight-fire-with-fire tactic, they might even shift the blame onto you, using criticisms and put downs to lower your self-esteem, making it harder for you to continue the confrontation.

• Dismissal: They might try to just shift gears, change the topic, and find excuses not to talk about it.

The bottom line is that confrontations probably won’t go as you hope.

A better approach is to set boundaries of behavior you won’t accept “If you continue to lie to me, I will end the conversation.”

This way, you stand up for yourself without being pulled into their world.

And it’s worth repeating, find some support, and then think seriously about ending the relationship, and how you would do that.
