The real war on science

A post in Judith Curry’s Climate etc pushed me to read a long essay from the City Journal Magazine by John Tierney. I hadn’t heard of either of them. The magazine is published by a right-wing think tank in New York, and focuses mostly on urban issues. John Tierney, according to Wikipedia, is a ‘contrarian’, which I see as a dismissive term. Forewarned, I went off to read the piece, and I think it is insightful. But then, I would probably be called a ‘contrarian’ too, by those who don’t like what I write, and believe they have the truth in them and should prevail. What I have done is to provide you with a few long extracts. There is a lot more, and some of it is American material that would be of less interest to Australian readers. I normally put other people’s writing in italics, but there is a lot of Tierney’s text, and italic is not the easiest font to read.

‘My liberal friends sometimes ask me why I don’t devote more of my science journalism to the sins of the Right. It’s fine to expose pseudoscience on the left, they say, but why aren’t you an equal-opportunity debunker? Why not write about conservatives’ threat to science? My friends don’t like my answer: because there isn’t much to write about. Conservatives just don’t have that much impact on science. I know that sounds strange to Democrats who decry Republican creationists and call themselves the “party of science.” But I’ve done my homework. I’ve read the Left’s indictments, including Chris Mooney’s bestseller, The Republican War on Science. I finished it with the same question about this war that I had at the outset: Where are the casualties? Where are the scientists who lost their jobs or their funding? What vital research has been corrupted or suppressed? What scientific debate has been silenced?

Yes, the book reveals that Republican creationists exist, but they don’t affect the biologists or anthropologists studying evolution. Yes, George W. Bush refused federal funding for embryonic stem-cell research, but that hardly put a stop to it (and not much changed after Barack Obama reversed the policy). Mooney rails at scientists and politicians who oppose government policies favored by progressives like himself, but if you’re looking for serious damage to the enterprise of science, he offers only three examples. All three are in his first chapter, during Mooney’s brief acknowledgment that leftists “here and there” have been guilty of “science abuse.” First, there’s the Left’s opposition to genetically modified foods, which stifled research into what could have been a second Green Revolution to feed Africa. Second, there’s the campaign by animal-rights activists against medical researchers, whose work has already been hampered and would be devastated if the activists succeeded in banning animal experimentation. Third, there’s the resistance in academia to studying the genetic underpinnings of human behavior, which has cut off many social scientists from the recent revolutions in genetics and neuroscience. Each of these abuses is far more significant than anything done by conservatives, and there are plenty of others.

The only successful war on science is the one waged by the Left. The danger from the Left does not arise from stupidity or dishonesty; those failings are bipartisan. Some surveys show that Republicans, particularly libertarians, are more scientifically literate than Democrats, but there’s plenty of ignorance all around. Both sides cherry-pick research and misrepresent evidence to support their agendas. Whoever’s in power, the White House plays politics in appointing advisory commissions and editing the executive summaries of their reports. Scientists of all ideologies exaggerate the importance of their own research and seek results that will bring them more attention and funding.

But two huge threats to science are peculiar to the Left—and they’re getting worse. The first threat is confirmation bias, the well-documented tendency of people to seek out and accept information that confirms their beliefs and prejudices. In a classic study of peer review, 75 psychologists were asked to referee a paper about the mental health of left-wing student activists. Some referees saw a version of the paper showing that the student activists’ mental health was above normal; others saw different data, showing it to be below normal. Sure enough, the more liberal referees were more likely to recommend publishing the paper favorable to the left-wing activists. When the conclusion went the other way, they quickly found problems with its methodology. Scientists try to avoid confirmation bias by exposing their work to peer review by critics with different views, but it’s increasingly difficult for liberals to find such critics.

Academics have traditionally leaned left politically, and many fields have essentially become monocultures, especially in the social sciences, where Democrats now outnumber Republicans by at least 8 to 1. (In sociology, where the ratio is 44 to 1, a student is much likelier to be taught by a Marxist than by a Republican.) The lopsided ratio has led to another well-documented phenomenon: people’s beliefs become more extreme when they’re surrounded by like-minded colleagues. They come to assume that their opinions are not only the norm but also the truth. Groupthink has become so routine that many scientists aren’t even aware of it. Social psychologists, who have extensively studied conscious and unconscious biases against out-groups, are quick to blame these biases for the underrepresentation of women or minorities in the business world and other institutions. But they’ve been mostly oblivious to their own diversity problem, which is vastly larger. Democrats outnumber Republicans at least 12 to 1 (perhaps 40 to 1) in social psychology, creating what Jonathan Haidt calls a “tribal-moral community” with its own “sacred values” about what’s worth studying and what’s taboo…’

‘Conservatives have been variously pathologized as unethical, antisocial, and irrational simply because they don’t share beliefs that seem self-evident to liberals. For instance, one study explored ethical decision making by asking people whether they would formally support a female colleague’s complaint of sexual harassment. There was no way to know if the complaint was justified, but anyone who didn’t automatically side with the woman was put in the unethical category. Another study asked people whether they believed that “in the long run, hard work usually brings a better life” — and then classified a yes answer as a “rationalization of inequality.” Another study asked people if they agreed that “the Earth has plenty of natural resources if we just learn how to develop them” — a view held by many experts in resource economics, but the psychologists pathologized it as a “denial of environmental realities…”’

‘And that brings us to the second great threat from the Left: its long tradition of mixing science and politics. To conservatives, the fundamental problem with the Left is what Friedrich Hayek called the fatal conceit: the delusion that experts are wise enough to redesign society. Conservatives distrust central planners, preferring to rely on traditional institutions that protect individuals’ “natural rights” against the power of the state. Leftists have much more confidence in experts and the state. Engels argued for “scientific socialism,” a redesign of society supposedly based on the scientific method. Communist intellectuals planned to mold the New Soviet Man. Progressives yearned for a society guided by impartial agencies unconstrained by old-fashioned politics and religion. Herbert Croly, founder of the New Republic and a leading light of progressivism, predicted that a “better future would derive from the beneficent activities of expert social engineers who would bring to the service of social ideals all the technical resources which research could discover.” This was all very flattering to scientists, one reason that so many of them leaned left. The Right cited scientific work when useful, but it didn’t enlist science to remake society—it still preferred guidance from traditional moralists and clerics. The Left saw scientists as the new high priests, offering them prestige, money, and power. The power too often corrupted. Over and over, scientists yielded to the temptation to exaggerate their expertise and moral authority, sometimes for horrendous purposes…’

I find it easy to see Australian parallels in this essay, but I will leave it to readers to draw their own. And let me commend Judith Curry’s own dissection of the Tierney essay and, as always, the Comments that follow on her website, 595 of them at last count. My own reaction has a twist. I don’t think that there is a ‘war on science’, at least in Australia. What I see is the misappropriation of science by activists of all kinds, for their own purposes, which has pushed aside the normal path of scientific research: think of a theory, test it experimentally or through field work, and accept the outcome. If the theory failed the test, then it is not good. Start again. We now have ‘model runs’ masquerading as experiments, and research offered to support previously defined policy. Too many scientists, it seems to me, shrug when they see bad science. Maybe they always did. But there seems a an awful lot of it about today.
