Self-centeredness and self-confidence are often confused with narcissism. It's true that "people who have an inflated sense of self" are narcissists. However, asking your favorite arrogant friend this one question will help you determine whether or not they're actually a narcissist.
For instance, some of the options included the following: 'I prefer to blend in with the crowd' (non-narcissistic response) versus 'I like to be the center of attention' (narcissistic response), or 'The thought of ruling the world frightens me' versus 'If I ruled the world, it would be a better place' (narcissistic response)."
But in a recent study published in the journal PLOS ONE, researchers looked at specific studies that determine narcissism.
The study says, "Participants had the option of rating their agreement on a scale of 1 (not very true of me) to 7 (very true of me). Because narcissists are confident in their answers and basically everything they do, they would likely tell you objectively what kind of person they are. Overall, the score just reveals where one would fall along a spectrum compared with others in the population."
The researchers determined that one question on the longer test could determine whether or not someone is a narcissist: "To what extent do you agree with the statement, 'I am a narcissist'? (Note: The word 'narcissist' means egotistical, self-focused, and vain)."
Ultimately, "Narcissists aren't afraid to tell you they're narcissists."
The best way to figure out if someone is a narcissist is to ask them blatantly, because they aren't ashamed to say yes. In fact, they'll be proud of their honesty.
