"When narcissists are confronted by people who disparage the legitimacy of their extravagant claims, they tend to react badly. They may plunge into depression--or become infuriated. As Gardner explained to the court, when narcissists are belittled or denigrated "they feel horrible. . . . They have this sense they're either grandiose, perfect, and beautiful people, or absolutely worthless. So if you challenge their grandiosity--these are the words in the diagnostic manual--'They respond with humiliation or rage.' Their reaction to criticism is intense."
