The most obvious change in American politics this century is the sorting of voters along educational lines. The Democrats are increasingly the party of educated urban elites; the GOP belongs to the white working class. The dispute is over suburban and minority voters. The latter still plump mostly for Democrats, although the party’s social radicalism is pushing them toward the GOP. Voters with impressive educational credentials tend to be Democrats, and those without them lean strongly Republican.
That one party is the educated party—that its members see themselves, in some respects accurately, as more cultured and informed than their opponents—has generated an intellectual pathology that is obvious to everyone but themselves. Adherents of the smart-people party have lost the capacity for self-criticism. Which on its face makes sense. If your views are by definition intelligent, those of your critics must be dumb. Who needs self-reflection?
We can start to understand the Democrats’ predicament by ridding ourselves of a set of metaphors. For a decade or more, we’ve been told that left and right live in “silos” or “bubbles” or “echo chambers” or “information cocoons.” The left watch MSNBC and read the New York Times, and the right watch Fox News and listen to talk radio.
Exacerbating this state of affairs, we’re told, are social-media platforms whose algorithms give politically attuned users only content they’re likely to agree with. Facile claims to the contrary, Facebook, Twitter and similar platforms don’t have this effect. A 2019 study, “Are Filter Bubbles Real?” by Axel Bruns of Queensland University Technology in Australia surveys a wide array of evidence and finds that social-media users on all sides get plenty of exposure to content with which they disagree. “Ironically,” Mr. Bruns writes in an aside, “echo chamber and filter bubble concepts may have become so popular with some journalists, media critics, and politicians because members of these professional classes are genuinely more likely to inhabit an information cocoon of sorts.”
