10 Narcissist Symptoms
9. Arrogant Demeanor
While not everyone who acts haughty is a narcissist, consistently arrogant mannerisms can be a sign of the disorder. People who display arrogance like to brag about their achievements. They talk about how they are smarter and more talented than others and presume they have skills they do not. They are self-appointed experts on every topic.
In certain situations, arrogance can come across as the positive personality trait of self-confidence. However, the presumptive behavior tends to express itself in all facets of life and is directed toward most people. Narcissists can be expected to treat others with contempt, belittling their competency and worth.
