To find out if someone is a Narcissist, just ask them if they are a Narcissist. It sounds tongue and cheek, but the answer could be surprisingly accurate.
You could click on this line to visit an interactive version of the 40 question Narcissistic Personality Inventory. Then have the subject go thru all 40 interactive screens.
Or you could simply ask him or her : “Are you a Narcissist?“
Their answer apparently could correspond well to the DSM test for Narcissistic Personality Disorder.
Prior studies have shown that such is the case. In 2012 as study titled “Honestly Arrogant or Simply Misunderstood? Narcissists’ Awareness of their Narcissism” was published. Click on this line to visit the Study publication site.
A newer study titled: “Measuring narcissism with a single question? A replication and extension of the Single-Item Narcissism Scale (SINS)” confirmed the results of the prior study. Click on this line to visit the Science Direct page which features this new study.
To me it sounds strange that a Narcissist would have no problem answering someone who has asked if they are a Narcissist. This all came from a recent post on Psychology Today which is titled: “How to Profile a Narcissist With One Simple Question.The one question a true narcissist cannot resist.“.
