Still, in economics there’s a famous distinction, developed by the great Chicago economist Frank Knight, between risk and uncertainty. Risk is when you don’t know exactly what will happen but nonetheless have a sense of the possibilities and their relative likelihood. Uncertainty is when you’re so unsure about the future that you have no way of calculating how likely various outcomes are. Business is betting that Trump is risky but not uncertain—he may shake things up, but he isn’t going to blow them up. What they’re not taking seriously is the possibility that Trump may be willing to do things—like start a trade war with China or a real war with Iran—whose outcomes would be truly uncertain. Trump won the Presidency by shattering norms and bucking expectations. Markets had better hope that he won’t govern the same way.

But increasingly, citizens don’t want to have those conversations. Rather, they want to weigh in and have their opinions treated with deep respect and their preferences honored not on the strength of their arguments or on the evidence they present but based on their feelings, emotions, and whatever stray information they may have picked up here or there along the way.
This is a very bad thing. A modern society cannot function without a social division of labor. No one is an expert on everything. We prosper because we specialize, developing formal and informal mechanisms and practices that allow us to trust one another in those specializations and gain the collective benefit of our individual expertise. If that trust dissipates, eventually both democracy and expertise will be fatally corrupted, because neither democratic leaders nor their expert advisers want to tangle with an ignorant electorate. At that point, expertise will no longer serve the public interest; it will serve the interest of whatever clique is paying its bills or taking the popular temperature at any given moment. And such an outcome is already perilously near.
