North Korea’s Kim Jong Un is correct about at least one thing: Donald Trump is a “dotard.” He is proudly ignorant, does not read, is crude and boorish, and lacks any sense of grace or humility.
In many ways, Trump is a living embodiment of the Dunning-Krueger effect — a social-psychological phenomenon where those with the least expertise and knowledge overestimate their own competence and systematically undervalue true expertise — on a grand stage.
Trump is also a brazen liar who has created his own reality organized around narcissism, egotism and self-aggrandizement. He is an overt racist who traffics in violent language and imagery, and who brags about sexually assaulting women. His willful embrace of ignorance amplify those other profound character defects.
