"...we briefly summarized some of the potentially harmful tendencies of narcissistic leaders, such as the following: defensively dismissing criticism and attacking critics, prioritizing the elevation of their public image over national well-being, refusing to admit they lack relevant knowledge instead of learning new information, making self-serving decisions instead of maintaining consistency with their stated beliefs, turning on anyone who stops singing their praises, and etc." - Jacob A. Fiala, a psychometrist at the University of Colorado at Colorado Springs Aging Center.
