One might think that the obvious answer to voter ignorance is education, and the answer to the more specific quandary of voter unreasonableness is perhaps some sort of civic reeducation. But the political philosopher Jason Brennan is having none of this argument. In his book Against Democracy, Brennan points to evidence that the generally rising education levels in the United States have not made citizens more knowledgeable about politics. Like many social scientists, he thinks there’s a simple explanation for why Americans remain so clueless: Ignorance is a rational choice. Since one’s individual vote has an infinitesimally small chance of actually deciding the outcome of an election, it simply isn’t worth the time and effort to bone up on policy basics—or even read the Constitution. As Brennan argues in another of his writings on the subject, democracy’s “essential flaw” is that it spreads power out widely, thereby removing any incentive for individual voters to use their own, more diffuse power wisely.
Of course, some voters seem happy to participate in the process nevertheless; they still display a passionate interest in political, and even constitutional, matters. But most of them, according to Brennan, treat politics like a spectator sport or, even worse, a brutal contact sport. The completely ignorant are what he calls “hobbits”; by contrast, those who root for one team and hate the other are “hooligans.” For hooligans, a little knowledge is a dangerous thing: They understand enough to be deeply convinced that their team is on the side of the angels and that the other side are devils (witness how 40 percent of Trump supporters in Florida thought that Hillary Clinton had literally emerged from hell). But they are incapable of rationally weighing policy options or even comprehending their own basic interests. For the hooligans, it’s all about identity.
