Brennan calls people who don’t bother to learn about politics hobbits, and he thinks it for the best if they stay home on Election Day. A second group of people enjoy political news as a recreation, following it with the partisan devotion of sports fans, and Brennan calls them hooligans. Third in his bestiary are vulcans, who investigate politics with scientific objectivity, respect opposing points of view, and carefully adjust their opinions to the facts, which they seek out diligently. It’s vulcans, presumably, who Brennan hopes will someday rule over us, but he doesn’t present compelling evidence that they really exist. In fact, one study he cites shows that even people with excellent math skills tend not to draw on them if doing so risks undermining a cherished political belief. This shouldn’t come as a surprise. In recent memory, sophisticated experts have been confident about many proposals that turned out to be disastrous—invading Iraq, having a single European currency, grinding subprime mortgages into the sausage known as collateralized debt obligations, and so on.
