Narcissism is a personality trait characterized by a grandiose sense of self-importance, a constant need for admiration, and a lack of empathy for others. It is considered a personality disorder when these traits significantly impair a person's functioning and relationships.
Whether a narcissist knows why they are the way they are can vary from person to person. Some narcissists may have some awareness of their behavior and personality traits, while others may be largely unaware or in denial about their narcissistic tendencies.
For some individuals with narcissistic traits, their behavior may be a coping mechanism or defense mechanism developed in response to past traumas, insecurities, or feelings of inadequacy. In these cases, they may have some insight into the origins of their behavior, but they may not necessarily recognize it as problematic or harmful.
On the other hand, some narcissists may lack the self-awareness to understand the impact of their behavior on others or recognize that their behavior is narcissistic. They might rationalize their actions, blame others, or externalize the causes of their problems.
It's important to note that not all people with narcissistic traits have a narcissistic personality disorder, and individuals can display varying degrees of narcissism. Additionally, seeking a formal diagnosis and treatment from a qualified mental health professional is essential for understanding and managing narcissistic personality disorder or any other psychological condition.
