Psychologists say they have developed and validated a new method to identify which people are narcissistic: just ask them.
In a series of 11 experiments involving more than 2,200 people of all ages, the researchers found they could reliably identify narcissistic people by asking them this exact question (including the note):
To what extent do you agree with this statement: "I am a narcissist." (Note: The word "narcissist" means egotistical, self-focused, and vain.)
Participants rated themselves on a scale of 1 (not very true of me) to 7 (very true of me).
How narcissistic are you? Take the test.
