You've probably seen the word "narcissist" thrown around online in headlines, on dating apps or in therapy-themed TikToks. But the label that people often unthinkingly slap on toxic bosses or reality TV villains hides a much more complicated psychological picture.

Psychologists have studied narcissism for many years, but over time, our understanding has evolved. One of the biggest changes is that today, narcissism is no longer seen as just grandiosity, arrogance or egotism.

Early scientific descriptions of narcissism focused on dominance, ambition and self-importance, all of which are traits associated with traditional masculine stereotypes.

That meant narcissistic tendencies in women were often misread or overlooked. When those traits show up as emotional sensitivity, insecurity or relational manipulation, they sometimes still are misdiagnosed as anxiety, mood disorders or borderline personality disorder traits.
