" 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. "
