Introduction

`Is my ex a narcissist?’

It’s a question that’s asked more and more. The answer is almost always `yes’. From podcasts to social media influencers, from YouTube channels to books narcissism is everywhere. And it’s big business too.

If you’re going through a separation/divorce and you’re looking for answers I’d put money on you noticing the word `narcissist’ everywhere.

I’ll speak plainly here: Being in a relationship with a narcissist is damaging, corrosive and abusive.

The usual advice given to someone who is dealing with them is to have nothing to do with them. It’s often good advice.

The problem is that this is hard when there are legal matters than need dealing with. When they involve children there’s a link between people that isn’t going away in the same way that a marriage can end with a divorce or finance settlement.

Spend any time at all on social media you’re going to see the word used a lot. You’ll find Tiktok influencers with millions of followers talking about it. There are large support groups out there with huge numbers of people discussing their experiences and strategies of dealing with narcissists. There are even highly successful coaches out there who help `survivors’ protect themselves and move on with their lives.

Even by just writing this blog post I am going out on a limb here too: Doing anything other than agreeing entirely with someone condemning an ex-partner who has been labelled as a narcissist often invites accusations of a lack of understanding or empathy and can result in anyone questioning things as being a narcissist too.

In the legal context, the word crops up a lot too. That’s the main context of this post. I’m going to give a perspective on the prevalence of narcissism and what it means for you if you’re in the family court with someone you suspect is a narcissist.

Bear with me, as I’m neither a psychiatrist or psychologist. I’m a McKenzie Friend, assisting people to represent themselves in child matters, financial settlements and divorce. Narcissism can play it’s part in these matters, but not always.

Here we go.

What is narcissism?

Let’s talk definitions so we’re clear. `Narcissism’ and Narcissistic Personality Disorder (NPD) are different things.

Narcissism is personality trait, not a mental illness. It involves self-centred behaviour, need for admiration, and lack of empathy. Many people can show narcissistic traits – especially under stress, in certain roles, or temporarily (e.g., during a breakup or career high). It doesn’t always cause major life problems or distress. Narcissism is common and exists on a spectrum: A little can be healthy (confidence, ambition), but too much can be toxic.

Most people exhibit these traits at times. You. Me. Your ex. Everyone. It’s part of being human. Being called a `narcissist’ is by and large a matter of opinion. It’s on a par with being called selfish, rude or lazy. It’s not a personality disorder.

But there’s a difference when it comes to Narcissistic Personality Disorder.

Narcissistic Personality Disorder (NPD) is a clinical diagnosis and a recognised personality disorder. For someone to be diagnosed they need to  meeting a specific set of criteria (e.g., DSM-5 in the US or the definition provided in the ICD-11 – the International Classification of Diseases, 11th edition), published by the World Health Organization (WHO) used in the UK and internationally). Their traits are extreme, rigid, and persistent over time. It causes significant problems in relationships, work, or daily life. The person usually lacks insight and rarely seeks help unless forced by a crisis (e.g., legal trouble or divorce). They’re not just being `full of themselves’ – it’s a deep, fragile, and defensive structure of the self.

This means that only a clinically neutral psychologist or psychiatrist who has carried out a full assessment that include interviews, questionnaires, behavioural history can formally diagnose someone. They look for long-standing patterns that match official criteria (like from the ICD-11 or DSM-5). If the traits are severe, persistent, and causing significant problems, they may diagnose NPD or a personality disorder with narcissistic traits.

The tl:dr means that calling someone a `narcissist’ is an opinion of someone, while NPD is a personality disorder that needs to be diagnosed. There are differences here.

Is my ex a narcissist?

I mentioned it earlier: Calling someone a `narcissist’ has become increasingly fashionable in recent years, especially in conversations about breakups, toxic relationships, and family conflict.

There are a number of reasons to explain this phenomena:

Here’s why that’s happening:

It explains emotional pain in simple terms.

When someone feels an ex partner has behaved selfishly, coldly, or manipulatively – especially in intimate relationships – it can leave the other person hurt and confused. Calling them a `narcissist’ gives a name to the experience and makes it feel less personal:

It wasn’t me – it was their disorder.

Social media & pop psychology

Platforms like TikTok, Instagram, and YouTube are full of bite-sized mental health content. Narcissism is:

• Easy to recognise in others (harder in ourselves)

• Emotionally charged and dramatic

• Click-worthy and relatable

But the downside is: many people confuse narcissistic traits with Narcissistic Personality Disorder (NPD) – see above!

It’s often used during or after breakups

Calling an ex a `narcissist’ can be a way of:

• Validating your own pain

• Gaining support from others

• Trying to make sense of betrayal or emotional chaos

It can also become a way to justify cutting contact or going no-contact.

It gives power back to the hurt parties

When someone feels mistreated, manipulated, or gaslit, diagnosing the other person (even unofficially) can feel empowering:

Now I know what they are. I’m not crazy.

But here’s the risk

• Not everyone who hurts you is a narcissist.

• Overuse of the label waters down its meaning and hurts real understanding.

• It can lead to diagnosing others unfairly – which isn’t neutral, and isn’t therapeutic.

I don’t know your ex (or you). I wasn’t present during your relationship. I’m not a psychologist or psychiatrist. Which means I am the last person to be able to say if your ex is a narcissist and/or someone who has NPD.

Which leads us to the next two sections: How likely is that your ex is one or the other (or both).

Narcissism – the data

Narcissism is less about loving oneself and more about controlling how others see you.

Dr. Sam Vaknin

Let’s get into the numbers. You can skip this part and go to the next paragraph if data isn’t your thing and you want to read what it actually means. It’s heavy going.

Feel free to skip this section (and the next one and head to `So does this mean they’re a narcissist?’ if you like!

Still here? The problem is, there’s no universally agreed cut-off point for being a narcissist. Instead researchers compare average scores across demographic groups and cultures. That’s because scores reflect the intensity of narcissistic characteristics rather than the presence of a disorder.

Prevalence and demographic patterns

Sub‑clinical narcissism in different environments

• Social media and digital life: Many studies link higher narcissistic traits to greater use of social media platforms and online self‑presentation. However, the direction of causality is debated: narcissistic individuals may be drawn to platforms that allow self‑promotion, while social media can also encourage narcissistic behaviour.

• Professions: Small studies suggest that professions involving competition and status (e.g., performing arts, politics, business leadership) attract individuals with higher narcissistic traits. Military recruits and medical students have shown elevated narcissism scores compared with general population samples.

Prevalence summary

Because sub‑clinical narcissism is a continuum rather than a diagnosis, researchers assess average scores rather than incidence. Nevertheless, the consistent findings above suggest that:

• Most people exhibit some narcissistic traits, but very high levels are uncommon. Extreme narcissism (top decile of scores) likely occurs in around 5-10 % of individuals depending on the measure and demographic group.

• Younger age, male gender, and certain cultural contexts (hierarchical or collectivistic societies) are associated with higher narcissism scores pmc.ncbi.nlm.nih.govsouthampton.ac.uk.

• Cross‑cultural variation exists; in some global surveys, collectivistic societies report higher grandiose exhibitionism and leadership traits psypost.org, while Western cultures show higher agentic admiration pmc.ncbi.nlm.nih.gov.

I’ll sum this up in `So does this mean they’re a narcissist (or have NPD)?‘ below.

NPD – the data

People with NPD don’t see relationships as mutual; they see them as opportunities for supply.

• Dr. Karyl McBride

This section is about NPD, not narcissism. Most of the data comes from the US meaning the DSM-IV criteria apply (as opposed to the ones used in the UK and most other countries). This will of course skew things but it can be hard to get balanced data. Here we go…

Check `What it all means’ if this makes you go cross eyed!

Interpretation

• Clinical NPD is relatively rare. The NESARC study (U.S.) found a 6.2 % lifetime prevalence, but most other community surveys suggest <1 % of people meet NPD criteriaresearch.uga.edu. Meta‑analyses of personality disorders show that cluster B disorders (which include NPD) account for about 2.8 % of the world’s populationremedypublications.com. The disorder is more frequently diagnosed in men (~75 % of cases)emedicine.medscape.com.

• Prevalence estimates vary because NPD is difficult to diagnose, individuals rarely seek treatment, and symptoms overlap with other disorders.

• Subclinical narcissistic traits (e.g., grandiosity, entitlement, lack of empathy) exist on a continuum and are more common than diagnosed NPD.

Cross‑cultural patterns of narcissism

Narcissism includes two broad forms – grandiose (overt self‑inflation, assertiveness) and vulnerable (feelings of inadequacy, hypersensitivity). Cross‑cultural studies comparing trait‑level narcissism across countries reveal important differences:

• Independent vs. interdependent cultures – A study comparing adults in Germany (individualistic) and Japan (collectivistic) found that vulnerable narcissism was more prevalent in Japan and was more strongly associated with mental‑health problems in Germanypmc.ncbi.nlm.nih.gov. The authors argue that cultural context shapes the form of narcissism; individualistic cultures encourage grandiose traits while interdependent cultures may foster vulnerable traitspmc.ncbi.nlm.nih.gov.

• Collectivistic vs. individualistic regions – A cross‑regional survey of 2,754 adults from the United States (51 %), Asia, Europe, Canada and Australia found that respondents from collectivistic societies (Asia and Africa) scored higher on the leadership/authority and grandiose exhibitionism facets of the Narcissism Personality Inventory than respondents from individualistic societiespsypost.org. The study cautioned that entitlement/exploitativeness may not be measured consistently across culturespsypost.org.

• Dark‑Triad study across 49 countries – A large study using the `Dirty Dozen’ scale examined narcissism, Machiavellianism and psychopathy in 49 countries. It found that advanced, modern democracies had lower average narcissism scores; countries with less intellectual autonomy, more hierarchy and embeddedness scored highersouthampton.ac.uk. Sex differences were larger in affluent democracies – women scored lower on narcissism than men – and smaller in less developed countriessouthampton.ac.uk.

These trait‑level studies suggest that cultural values, economic development and gender roles influence expressions of narcissism. However, they measure narcissism as a personality trait, not as a clinical disorder; cross‑cultural epidemiological data for NPD are lacking.

Narcissism in family‑court and legal contexts

Evidence from published case‑law analyses

Systematic research on the prevalence of NPD or other Cluster B disorders in family courts is scarce, partly because courts rarely record litigants’ diagnoses. One of the few empirical datasets is a 2018 analysis of U.S. federal and state case law:

• The authors searched 1,399 published cases (1980-2016) in which litigants were described as having Antisocial, Borderline, Narcissistic or Histrionic Personality Disorder – the four Cluster B disorders.

• Narcissistic Personality Disorder appeared in 102 cases. Family‑law cases (including child custody, divorce and child‑support disputes) accounted for 18 of these 102 NPD cases (~17.6 %) pmc.ncbi.nlm.nih.gov.

• Across all Cluster B litigants, family‑law cases comprised 10.2 % of the sample pmc.ncbi.nlm.nih.gov. NPD litigants had the lowest success rate (18.6 %) in litigation among Cluster B disorders p mc.ncbi.nlm.nih.gov.

• The study noted that personality disorders were disproportionately represented in the judicial system -cluster B disorders occur in >50 % of psychiatric outpatient samples and >70 % of prison populations, compared with ~10 % in the general population pmc.ncbi.nlm.nih.gov.

High‑conflict family‑court experiences

Although quantitative prevalence data are lacking, numerous legal commentaries and psychological writings draw attention to the overrepresentation of personality‑disordered individuals in high‑conflict divorce and custody disputes:

• In Impasses of Divorce (1988), mediation specialists observed that parents who engage in prolonged custody battles often display borderline personality‑disorder patterns and other Cluster B traits; these individuals `consume an inordinate amount of time and energy of family lawyers and the family court system’ highconflictinstitute.com.

• The High Conflict Institute, which trains legal professionals, notes that over 10 % of the adult population meets criteria for a personality disorder highconflictinstitute.com and that high‑conflict clients in family courts frequently have Cluster B traits highconflictinstitute.com.

• A scoping review of parental mental illness in family courts (2023) found that mental illness is commonly raised in parenting disputes; some court judgments refer to parents exhibiting Cluster B personality traits (including narcissistic personality disorder) even when no formal diagnosis is provided link.springer.com. Parents reported that their mental illness was often used against them, and 88 % of surveyed parents who had a mental illness said the illness was raised in court link.springer.com.

Gaps and limitations

• No global prevalence data – Outside of the U.S. case‑law analysis, there is no systematic worldwide data on how often NPD or other personality disorders appear in family‑court proceedings. Courts seldom document psychiatric diagnoses, and many jurisdictions avoid labels such as `narcissism’ during proceedings bishopandsewell.co.uk.

• Stigma and under‑diagnosis – People with personality disorders are often unaware of their condition and rarely seek treatment highconflictinstitute.com. In family courts, mental‑health issues may be hidden or weaponised, making accurate data difficult to obtain link.springer.com.

• Lack of cross‑cultural studies – Most available research examines U.S. or Western contexts; there are no comparative studies of NPD prevalence in family courts across different countries.

So does this mean they’re a narcissist (or have NPD)?

If you’ve read those last two sections you may wonder what it means. To sum it all up however we can say the data available says.

For narcissism (not NPD)

1. Narcissism is common. Most people display narcissistic traits at some point, but few people show very high levels. The people with the highest levels represent 5-10% of the population, depending on the group of people you’re looking at.
2. It tends to decline with age (but the people with higher levels usually tend to remain higher).
3. Men are very slightly more likely to show narcissistic tendencies than women.
4. People from countries in Asia or Africa score higher on some aspects of narcissism than people in Europe, the USA or Australia.
5. Democracies tend to have lower levels of people with narcissists than other countries.
6. Social media amplifies perception of narcissism, but it could be that social media attracts people with narcissistic traits instead.
7. Some jobs attract people with narcissistic traits (e.g., performing arts, politics, business leadership, medicine and the military).

For NPD (not narcissism)

• General population – True Narcissistic Personality Disorder is relatively uncommon. Community surveys in the United States estimate prevalence between 0.5 % and 6.2 %, with men more often diagnosed than women emedicine.medscape.compmc.ncbi.nlm.nih.gov. Global meta‑analyses suggest that cluster B personality disorders, which include NPD, account for roughly 2.8 % of the world’s population remedypublications.com. Subclinical narcissistic traits are more common and vary across cultures; modern democracies tend to have lower trait‑level narcissism southampton.ac.uk, while collectivistic societies may report higher levels of specific narcissism facets psypost.org.

• Family‑court settings – Empirical research shows that personality‑disordered litigants are over‑represented in high‑conflict cases. A U.S. case‑law analysis found that family‑law matters accounted for ≈18 % of narcissistic personality‑disorder cases in courts pmc.ncbi.nlm.nih.gov, even though NPD is very rare in the general population. Qualitative reports and scoping reviews describe a `high percentage of personality disorders’ among protracted custody disputes highconflictinstitute.com. However, there is no reliable global prevalence estimate of narcissism in family courts due to under‑diagnosis, stigma and lack of data collection.

• Implications – Because personality‑disordered individuals may drive lengthy, adversarial disputes and can manipulate legal processes, many family‑law experts advocate education and training for judges and lawyers to recognise and manage these cases highconflictinstitute.com. Research also highlights the need for trauma‑informed, culturally sensitive approaches that avoid stigmatisation while protecting children and supporting parents with mental‑health challenges link.springer.com.

Or more simply…

1. Studies show a minimum of less than 1% and a maximum of 6.2% of of people have Narcissistic Personality Disorder (with 7.8% for all personality disorders which include antisocial personality disorder, borderline personality disorder, histrionic personality disorder, and narcissistic personality disorder).
2. 75% of people diagnosed are male.

3. It’s  difficult to diagnose, individuals rarely seek treatment, and symptoms overlap with other disorders.

4. Subclinical narcissistic traits (e.g., grandiosity, entitlement, lack of empathy) exist on a continuum and are more common than diagnosed NPD

The simplest way of summing this up is this:

Most people show narcissistic tendencies. People with narcissistic personality disorder are rare.

Should I be calling them a narcissist at all?

Based on the stats…no.

OK, I get it. You can reasonably call someone who shows narcissistic traits a `narcissist’. Which means calling your ex a narcissisit – in court, on social media or when talking to your friends may strictly be correct.

But the statistics show that you likely exhibit at least some of these traits which means you could be similarly described…

I’m here to help you with your family law matter. I’m going to tell you labels are seldom helpful. And the term `narcissist’ isn’t a compliment and is best avoided if you’re hoping to dial down animosity as opposed to escalating matters. You should most definitely not be calling them one in court, nor proving they are and especially not claiming they have narcissistic personality disorder in your family law case unless they have been diagnosed by a court appointed professional (part 25 expert).

As always, describe the behaviour – don’t label it. Talk about how it has impacted your child (or their conduct in the rare cases is it is dealt with finance cases under Section 25 of the Matrimonial Causes Act) but leave it at that.
