The rise of social media has been great in many ways. In a media environment with endless inputs and outlets, citizens can inform and entertain one another, organize more easily and hold their leaders accountable. But it also turns out that when everyone can customize his or her own information bubble, it’s easier for demagogues to deploy made-up facts to suit the story they want to tell.
That’s what Mr. Trump has done. For him, facts aren’t the point; trust is. Like any autocrat, he wins his followers’ trust — let’s call it a blind trust — by lying so often and so brazenly that millions of people give up on trying to distinguish truth from falsehood. Whether the lie is about millions of noncitizens voting illegally, or the crime rate, or President Obama’s citizenship, it doesn’t matter: In a confusing world of competing, shouted “truths,” the simplest solution is to trust in your leader. As Mr. Trump is fond of saying, “I alone can fix it.”
