In the lonely crowd of experts

David Brooks voices concerns that have also been voiced by your humble blogger in his column today:  Conservatism was once a frankly elitist movement. Conservatives stood against radical egalitarianism and the destruction of rigorous standards. They stood up for classical education, hard-earned knowledge, experience and prudence. Wisdom was acquired through immersion in the best that has been thought and said. But, especially in America, there has always been a separate, populist, strain. For those in this school, book knowledge is suspect but practical knowledge is respected. The city is corrupting and the universities are kindergartens for overeducated fools. The elitists favor sophistication, but the common-sense folk favor simplicity. The elitists favor deliberation, but the populists favor instinct.... I would have more sympathy for this view if I hadn’t just lived through the last eight years. For if the Bush administration was anything, it was the anti-establishment attitude put into executive practice. And the problem with this attitude is that, especially in his first term, it made Bush inept at governance. It turns out that governance, the creation and execution of policy, is hard. It requires acquired skills. Most of all, it requires prudence. This is certainly one reason why the founders wanted a republic and not a democracy -- in republics, leaders do have the ability to resist the populist temptation a little more.  What's interesting is how this resistance to experts plays out in campaign tactics.  Consider, for example, this Washington Post story by Shamkar Vedantum (hat tip:  Kevin Drum): [A]a series of new experiments show that misinformation can exercise a ghostly influence on people's minds after it has been debunked -- even among people who recognize it as misinformation. In some cases, correcting misinformation serves to increase the power of bad information. In experiments conducted by political scientist John Bullock at Yale University, volunteers were given various items of political misinformation from real life. One group of volunteers was shown a transcript of an ad created by NARAL Pro-Choice America that accused John G. Roberts Jr., President Bush's nominee to the Supreme Court at the time, of "supporting violent fringe groups and a convicted clinic bomber." A variety of psychological experiments have shown that political misinformation primarily works by feeding into people's preexisting views. People who did not like Roberts to begin with, then, ought to have been most receptive to the damaging allegation, and this is exactly what Bullock found. Democrats were far more likely than Republicans to disapprove of Roberts after hearing the allegation. Bullock then showed volunteers a refutation of the ad by abortion-rights supporters. He also told the volunteers that the advocacy group had withdrawn the ad. Although 56 percent of Democrats had originally disapproved of Roberts before hearing the misinformation, 80 percent of Democrats disapproved of the Supreme Court nominee afterward. Upon hearing the refutation, Democratic disapproval of Roberts dropped only to 72 percent. Republican disapproval of Roberts rose after hearing the misinformation but vanished upon hearing the correct information. The damaging charge, in other words, continued to have an effect even after it was debunked among precisely those people predisposed to buy the bad information in the first place.... Political scientists Brendan Nyhan and Jason Reifler provided two groups of volunteers with the Bush administration's prewar claims that Iraq had weapons of mass destruction. One group was given a refutation -- the comprehensive 2004 Duelfer report that concluded that Iraq did not have weapons of mass destruction before the United States invaded in 2003. Thirty-four percent of conservatives told only about the Bush administration's claims thought Iraq had hidden or destroyed its weapons before the U.S. invasion, but 64 percent of conservatives who heard both claim and refutation thought that Iraq really did have the weapons. The refutation, in other words, made the misinformation worse. A similar "backfire effect" also influenced conservatives told about Bush administration assertions that tax cuts increase federal revenue. One group was offered a refutation by prominent economists that included current and former Bush administration officials. About 35 percent of conservatives told about the Bush claim believed it; 67 percent of those provided with both assertion and refutation believed that tax cuts increase revenue. This suggests:  The Obama strategy of painting McCain as a liar won't improve perceptions of Obama -- at best they'll simply convince people McCain is a liar. There is a terrible incentive for any "expert" -- i.e., credentialed enough to merit press attention -- to make a wild-ass claim that makes the papers.  Since the first claimer apparently has first-mover advantage, refutation becomes irrelevant.  No one gives a flying f%$# what I think about this.
