The solution to finding out whether someone is a narcissist or not is apparently very simple.

Researchers have found that the best way to identify narcissism is to just ask people if they are narcissists. The real narcissists will speak right up and say that that are according to a new study reported by USA Today.

"People who are not narcissists would never say that they. Somebody who is a narcissist doesn't think it's all that bad and is maybe even a little proud of it," explained Sara Konrath, a researcher at Indiana University in Indianapolis.

Konrath and colleagues at Ohio State University and Gettysburg College developed the one-question test for narcissism in trials involving 2,250 people.

Subjects were reportedly told that the word "narcissist" means "egotistical, self-focused and vain." When asked the question, "To what extent do you agree with this statement: 'I am a narcissist?" those who agreed chose a 6 or 7 on a 7-point scale.

These were the same people who scored high for narcissism on a traditional 40-item questionnaire test. The self-proclaimed narcissists made up about 5% of test-takers, according to the website.

For those who don't know, narcissistic personality disorder is considered a disorder with symptoms that vary from expecting praise and admiration to fantasizing about power, success and attractiveness, according to the Medical Daily.

"Overall, narcissism is problematic for both individuals and society. Those who think they are already great don't try to improve themselves. And narcissism is bad for society because people who are only thinking of themselves and their own interests are less helpful to others," stated the study's co-author Brad Bushman.
