Diagnosed narcissist shares the one question to ask someone to find out if they're narcissistic

A diagnosed narcissist has shared the one question you should consider asking if you believe someone you know may have the condition.

Previously a way to insult anyone who appeared vain or self centred - with the name being inspired by the Greek myth of Narcissus - narcissism, or narcissistic personality disorder (NPD), is a now clinically diagnosed condition. Symptoms of NPD can include a distinct lack of empathy for others, a grandiose sense of entitlement and a chronic need for admiration.

Research shared via the BBC estimates that 1 in 20 people in the UK may have the condition.

Identifying a narcissist isn't straightforward, especially as the term gets thrown around very easily when describing selfish behaviour, however one man has revealed the one question he thinks you should ask.

Taking to TikTok, a user who goes by the name of @thenamelessnarcissist, recalled how he came to the realisation after having a conversation with a friend who is also a diagnosed narcissist.

The question you need to ask? "Ask them 'don't you think there are just objectively better and worse people in the world... and the rest of the world just likes to ignore that?" the creator revealed.

"Even better if you add something that you and that person are both part of the upper echelons."

He went on to explain how hearing this question for the first time almost felt like a lightbulb moment to him, adding: "I was shocked that finally I had met somebody else who could see the reality of things."

Now this many not seem like the most obvious thing you'd think to bring up in a day-to-day conversation, however the creator went on to explain exactly how this question gives you an insight into how a narcissist's mind works.

"Narcissists view the world through that lens, through the ideas that there are some people who have more inherent self worth and some people who have less self worth," he explained.

"That is an essential core belief that drives their actions. And it is why constantly they're trying to prove they are part of the better people, because deep down they think they are the worst people."

This isn't the only way to tell if someone may have NPD, with psychiatrist Dr. Tharaka Gunarathne revealing how a relationship with a narcissist can leave you feeling.

"It feels like your sense of identity has been removed or hoovered out of your own mind," he said during an interview with BBC's Morning Live.

"This can be really disconcerting... as identity is a really important part of self."
