"Consider the various ways in which Trump's campaign represented a one-man campaign against established knowledge. He was one of the original "birthers" who demanded that Barack Obama prove his American citizenship. He quoted the National Enquirer approvingly as a source of news. He sided with antivaccine activism. He admitted that he gets most of his information on foreign policy from "the shows" on Sunday morning television. He suggested that Supreme Court Justice Antonin Scalia, who died from natural causes in early 2016, might have been murdered. And he charged that the father of one of his opponents (Ted Cruz) was involved in the Mother of All Conspiracy Theories, the assassination of John F. Kennedy."
