Common traits of a narcissist are a sense of self-importance and the belief that he is special and superior to others, according to Psychology Today. A narcissist also has a sense of entitlement and a lack of empathy towards others.
Another common trait of narcissism is the negative reaction to criticism, notes Psychology Today. This is sometimes actual criticism against the person or the work he does; at other times, it is what he perceives to be a negative evaluation of his performance. A narcissist tends to change the subject when his personality or performance is heavily criticized. It is not uncommon for a narcissist to have low self-esteem due to a complicated psyche. On the other end of the spectrum, self-righteousness is common among narcissists.
People with these traits of narcissism have narcissistic personality disorder, according to Psych Central. With this personality disorder, the person feels a high level of grandiosity, sometimes in fantasy and not reality. Someone with a case of narcissistic personality disorder is constantly in need of admiration and doesn’t understand when he does not get it. This person also believes that his existence is important to people in his life, including his friends and family.
