How wonderful to return to a free country, I thought as I stepped off the plane from Beijing at Washington Dulles. No more censorship, no more official lies, no more kowtowing to high officials who gained power by their mindless repetition of party dogma…

Then alas I opened my browser and read the dump-on-Manzi comments on NRO’s The Corner. Manzi had deviated from the One Correct Way of Mark Levin Thought, and all his former colleagues had been summoned together to Denounce and Struggle Against Him.

Not one stood up to be counted in Manzi’s defense, not even colleagues whom Manzi might have had reason to regard as close personal friends. (Take a second to notice whose bylines are missing from yesterday’s discussions.)

What makes this episode all the more remarkable is that Manzi is actually a member of NR’s board of trustees – i.e., somebody who might claim a little more scope to speak his mind. But even for trustees, there are limits, and Manzi crossed them.

It’s important to understand what exactly the limit is.

Manzi could have safely disputed Levin’s claims on global warming if he had observed a couple of conditions. First, acknowledge Liberty and Tyranny as a good and important book. Second, acknowledge Levin’s “service” (i.e., leadership) of the conservative cause. Third, isolate criticisms to one particular finite point – avoid drawing any larger conclusions – and be sure to wrap any criticisms in a blanket of compliments. Just because one particular chapter happens to be slovenly, ignorant, and hysterical should not lead you to question the intellectual merit of the book as a whole.

Manzi negligently violated the rules, and the results are as you see.

The episode reminds me of a conversation I had with a friend a year ago, shortly after I published my piece on Rush Limbaugh in Newsweek. I won’t embarrass my friend by mentioning his name, but if I did, you’d certainly recognize it.

My friend: “You aren’t really mad at Rush Limbaugh you know.”

Me: “I’m not? I thought I was.”

My friend: “You’re not even mad at Fox News. You want to win elections, you know that the troops have to be mobilized, somebody has to get them fired up, and you don’t fire them up with Milton Friedman and James Q. Wilson. You are mad at the conservative intellectual elites. They’re the ones who are supposed to uphold intellectual standards, to sift actual facts from what you call ‘pretend information’. Rush Limbaugh isn’t any worse than he was 20 years ago. But 20 years ago, conservatism offered something more than Rush Limbaugh. Since then, the conservative elite has collapsed. Blame them, not talk radio.”

What happened to Manzi is a perfect illustration of this elite collapse.

Reading through the comments in the Corner, there’s no mistaking who’s in charge, who’s subservient. Two Corner contributors complained about Manzi’s “tone.” Levin is the most vituperative radio host this side of Mike Savage – but imagine anyone at The Corner complaining about Levin’s tone!

Conservatism has always had both elite and popular wings, and in the past they worked together productively. Fred Schwarz drew tens of thousands to his Christian Anti-Communist Crusade in the early 1960s, at the same time as Milton Friedman was publishing Capitalism and Freedom; F.A. Hayek, The Constitution of Liberty; and Edward Banfield, The Moral Basis of a Backward Society. Nobody however demanded that Milton Friedman hail Schwarz’s pamphlets as serious contributions to conservative thought, in the way that the Cornerites demand that Manzi kiss Levin’s ring.

It’s different now, to conservatism’s present shame and future detriment.

Here's the National Review Online post that started the controversy. Personally, I'm glad to see some conservatives standing up to the anti-intellectual idiocy that has permeated the right in this country over the past fifteen years.

Liberty and Tyranny and Epistemic Closure [Jim Manzi]

Jonah notes Ross Douthat’s very interesting post, in which Ross had this to say:

Conservative domestic policy would be in better shape if conservative magazines and conservative columnists were more willing to call out Republican politicians (and, to a lesser extent, conservative entertainers) for offering bromides instead of substance, and for pandering instead of grappling with real policy questions.

I thought some about this over the past few days, and took this as a direct challenge.

Here goes.

I started to read Mark Levin’s massive bestseller Liberty and Tyranny a number of months ago as debate swirled around it. I wasn’t expecting a PhD thesis (and in fact had hoped to write a post supporting the book as a well-reasoned case for certain principles that upset academics just because it didn’t employ a bunch of pseudo-intellectual tropes). But when I waded into the first couple of chapters, I found that — while I had a lot of sympathy for many of its basic points — it seemed to all but ignore the most obvious counter-arguments that could be raised to any of its assertions. This sounds to me like a pretty good plain English meaning of epistemic closure. The problem with this, of course, is that unwillingness to confront the strongest evidence or arguments contrary to our own beliefs normally means we fail to learn quickly, and therefore persist in correctable error.

I’m not expert on many topics the book addresses, so I flipped to its treatment of a subject that I’ve spent some time studying — global warming — in order to see how it treated a controversy in which I’m at least familiar with the various viewpoints and some of the technical detail.

It was awful. It was so bad that it was like the proverbial clock that chimes 13 times — not only is it obviously wrong, but it is so wrong that it leads you to question every other piece of information it has ever provided.

Levin argues that human-caused global warming is nothing to worry about, and merely an excuse for the Enviro-Statists (capitalization in the original) to seize more power. It reads like a bunch of pasted-together quotes and stories based on some quick Google searches by somebody who knows very little about the topic, and can’t be bothered to learn. After pages devoted to talking about prior global cooling fears, and some ridiculous or cynical comments by advocates for emissions restrictions (and one quote from Richard Lindzen, a very serious climate scientist who disputes the estimated magnitude of the greenhouse effect, but not its existence), he gets to the key question on page 184 (eBook edition):

[D]oes carbon dioxide actually affect temperature levels?

Levin does not attempt to answer this question by making a fundamental argument that proceeds from evidence available for common inspection through a defined line of logic to a scientific view. Instead, he argues from authority by citing experts who believe that the answer to this question is pretty much no. Who are they? An associate professor of astrophysics, a geologist, and an astronaut.

But he says that these are just examples:

There are so many experts who reject the notion of man-made global warming and the historical claims about carbon dioxide they are too numerous to list here.

He goes on to cite a petition “rejecting the theory of human-caused global warming” sponsored by the Oregon Institute of Science and Medicine and signed by more than 31,000 scientists. There are a few problems with this survey that Levin doesn’t mention. More than 20,000 of these “scientists” lack PhDs in any field. There was very little quality control: At least one person signed it as Spice Girl Geri Halliwell. Scientific American did the hard work of actually contacting a sample of individual signatories, and estimated that there are about 200 climate scientists who agree with the statement in the petition among the signatories. And most important by far, the text of the petition is not close to Levin’s claim of rejecting the notion of man-made global warming. In the key sentence it says that signatories do not believe that there is compelling scientific evidence that human release of greenhouse gases will cause catastrophic heating and disruption of the earth’s climate. Depending on the definition of “catastrophic,” I could agree to that. Yet I don’t reject the notion of man-made global warming.

On one side of the scale of Levin’s argument from authority, then, we have three scientists speaking outside their areas of central expertise, plus a dodgy petition. What’s on the other side of the scale that Levin doesn’t mention to his readers?

Among the organizations that don’t reject the notion of man-made global warming are: the U.S. National Academy of Sciences; The Royal Society; the national science academies of Australia, Belgium, Brazil, Canada, China, France, Germany, Ireland, Italy, India, Japan, Mexico, New Zealand. Russia, South Africa, and Sweden; the U.S. National Research Council; the American Association for the Advancement of Science; the American Chemical Society; the American Physical Society; the American Geophysical Union; and the World Meteorological Organization. That is, Levin’s argument from authority is empty.

Of course, this roll call could be arbitrarily long and illustrious, and that does not make them right. Groupthink or corruption is always possible, and maybe the entire global scientific establishment is wrong. Does he think that these various scientists are somehow unaware that Newsweek had an article on global cooling in the 1970s? Or are they aware of the evidence in his book, but are too trapped by their assumptions to be able to incorporate this data rationally? Or does he believe that the whole thing is a con in which thousands of scientists have colluded across decades and continents to fool such gullible naifs as the U.S. Congressional Budget Office, numerous White House science advisors, Margaret Thatcher, and so on? Are the Queen of England and the Trilateral Commission in on it too?

But what evidence does Levin present for any of this amazing incompetence or conspiracy beyond that already cited? None. He simply moves on to criticisms of proposed solutions. This is wingnuttery.

There are many reasons to write a book. One view is that a book is just another consumer product, and if people want to buy jalapeno-and-oyster flavored ice cream, then companies will sell it to them. If the point of Liberty and Tyranny was to sell a lot of copies, it was obviously an excellent book. Further, despite what intellectuals will often claim, most people (including me) don’t really want their assumptions challenged most of the time (e.g., the most intense readers of automobile ads are people who have just bought the advertised car, because they want to validate their already-made decision). I get that people often want comfort food when they read. Fair enough. But if you’re someone who read this book in order to help you form an honest opinion about global warming, then you were suckered. Liberty and Tyranny does not present a reasoned overview of the global warming debate; it doesn’t even present a reasoned argument for a specific point of view, other than that of willful ignorance. This section of the book is an almost perfect example of epistemic closure.
