He knows everything already so he doesn't need experts

He said in a series of interviews that he does not need to read extensively because he reaches the right decisions “with very little knowledge other than the knowledge I [already] had, plus the words ‘common sense,’ because I have a lot of common sense and I have a lot of business ability.”

Trump said he is skeptical of experts because “they can’t see the forest for the trees.” He believes that when he makes decisions, people see that he instinctively knows the right thing to do: “A lot of people said, ‘Man, he was more accurate than guys who have studied it all the time.’ ”

Trump’s approach goes beyond the chief executive manner of Reagan or the younger Bush. “We’ve had presidents who have reveled in their lack of erudition,” said Allan Lichtman, a political historian at American University, citing Warren Harding and Lyndon Johnson as leaders who scoffed at academics and other experts. “But Trump is really something of an outlier with this idea that knowing things is almost a distraction. He doesn’t have a historical anchor, so you see his gut changing on issues from moment to moment.”

One day last month, Trump had a visit from a delegation of prominent executives in the oil, steel and retail industries, and one of the executives told Trump that the Chinese were taking advantage of the United States. “He said, ‘I’d like to send you a report,’ ” Trump recalled. “He said, ‘I’d love to be able to send you’ — oh boy, he’s got a lengthy report, hundreds of pages. . . . I said, ‘Do me a favor: Don’t send me a report. Send me, like, three pages.’ ”

Trump said reading long documents is a waste of time because he absorbs the gist of an issue very quickly. “I’m a very efficient guy,” he said. “Now, I could also do it verbally, which is fine. I’d always rather have — I want it short. There’s no reason to do hundreds of pages because I know exactly what it is.”
