Narcissism

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. 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.

Narcissism exists on a continuum that ranges from normal to abnormal personality expression. 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, leading to functional impairment and psychosocial disability. It has also been discussed in dark triad studies, along with subclinical psychopathy and Machiavellianism.
