Narcissism is a self-centered personality style characterized as having an excessive preoccupation with oneself and one's own needs, often at the expense of others.[1][2] Narcissism, named after the Greek mythological figure Narcissus, has evolved into a psychological concept studied extensively since the early 20th century, and it has been deemed highly relevant in various societal domains.[3]
Narcissism exists on a continuum that ranges from normal to abnormal personality expression.[4] While many psychologists believe that a moderate degree of narcissism is normal and healthy in humans, there are also more extreme forms, observable particularly in people who have a personality condition like narcissistic personality disorder (NPD), where one's narcissistic qualities become pathological,[4][5] leading to functional impairment and psychosocial disability.[6] It has also been discussed in dark triad studies, along with subclinical psychopathy and Machiavellianism.[7][8][9]
