Dealing with complicated problems is an occupational hazard faced by outsiders in all fields — and there's never been a president who is more of an outsider to the realm of public policy. Consequently, a lot of his assertions about critical matters of public concern are based on ... nothing at all. As president, he is fitfully coming into contact with concrete policy choices, actual information, and well-informed people. And it's making a difference.
That's the dynamic behind many of this spring's jarring policy reversals on backing out of NATO, Chinese currency manipulation, and relations with Russia.
And to the extent that Trump is replacing ignorance with information and bad policy with good policy, it deserves to be celebrated rather than mocked. But the wild swings themselves are disturbing and have consequences. And Trump's actual habits around issuing ignorant pronouncements and failing to obtain sound information don't appear to have changed. Most fundamentally of all, Trump's laziness and ignorance leave him easily manipulated.
Some of the things he's "learned" since taking office aren't true, like when Paul Ryan convinced him Republicans had to do health care reform before tax reform. And as his equal-opportunity openness to both new information and new "information" become clearer to all interested parties, the race will be on to manipulate the president and incite further chaos in American public policy.
