You are correct that many narcissists, especially those with narcissistic personality disorder (NPD), are unlikely to admit that they have a problem or identify themselves as narcissists. Narcissists often have a deeply ingrained sense of grandiosity and entitlement, making it difficult for them to recognize their own flaws or take responsibility for their actions.
However, there can be exceptions, and some individuals with narcissistic traits might eventually acknowledge their behavior and seek help or self-awareness. These individuals may be referred to as "vulnerable" or "covert" narcissists, and they can display a different set of characteristics compared to the more overt or grandiose narcissists.
Covert narcissists tend to be more introverted and may present themselves as sensitive, victim-like, or self-effacing, making it harder to detect their narcissistic traits. They might also have a strong need for admiration and validation but express it in subtler ways compared to their overt counterparts. Because of their inward focus and feelings of inadequacy, they may be more open to self-reflection and may occasionally admit to their flaws or tendencies.
It's important to note that even if someone admits to having narcissistic traits, it does not necessarily mean they have NPD or that they are willing or able to change their behavior. True change and growth require consistent effort and commitment, often with the help of therapy or counseling.
If your son has acknowledged his narcissistic tendencies, it may be an opportunity for him to explore self-awareness and work towards healthier relationships and personal growth. Encouraging him to seek professional help from a mental health professional experienced in dealing with narcissism could be beneficial. However, keep in mind that change is a challenging process, and it ultimately depends on your son's willingness and dedication to addressing his behaviors and patterns.
