Trump - a bit off the mark

But making suggestions was deeply complicated. Here was, arguably, the central issue of the Trump presidency, informing every aspect of Trumpian policy and leadership: he didn’t process information in any conventional sense—or, in a way, he didn’t process it at all. Trump didn’t read. He didn’t really even skim. If it was print, it might as well not exist. Some believed that for all practical purposes he was no more than semiliterate. (There was some argument about this, because he could read headlines and articles about himself, or at least headlines on articles about himself, and the gossip squibs on the New York Post’s Page Six.) Some thought him dyslexic; certainly his comprehension was limited. Others concluded that he didn’t read because he just didn’t have to, and that in fact this was one of his key attributes as a populist. He was postliterate—total television. But not only didn’t he read, he didn’t listen. He preferred to be the person talking. And he trusted his own expertise—no matter how paltry or irrelevant—more than anyone else’s. What’s more, he had an extremely short attention span, even when he thought you were worthy of attention. The organization therefore needed a set of internal rationalizations that would allow it to trust a man who, while he knew little, was entirely confident of his own gut instincts and reflexive opinions, however frequently they might change.
