Hit & Run : Reason.com: "Tierney correctly observes lots of leftwing partisans forget that science is applied skepticism and instead treat "science" as a collection of dogmas. What dogmas? "The Left's zeal to find new reasons to regulate has led to pseudoscientific scaremongering about "Frankenfoods," transfats, BPA in plastic, mobile phones, electronic cigarettes, power lines, fracking, and nuclear energy," summarizes Tierney. And let's not forget Rachel Carson's thoroughly debunked claim that exposure to trace amounts of synthetic chemicals is a major cause of cancer or the assertion the current average consumption of salt is a major cause of cardiovascular disease."
The Real War on Science | City Journal: "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."
...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.”
...The Blank Slate dogma has perpetuated a liberal version of creationism: the belief that there has been no evolution in modern humans since they left their ancestral homeland in Africa some 50,000 years ago. Except for a few genetic changes in skin color and other superficial qualities, humans everywhere are supposedly alike because there hasn’t been enough time for significant differences to evolve in their brains and innate behavior. This belief was plausible when biologists assumed that evolution was a slow process, but the decoding of the human genome has disproved it, as Nicholas Wade (a former colleague of mine at the New York Times) reported in his 2015 book, A Troublesome Inheritance. “Human evolution has been recent, copious and regional,” writes Wade, noting that at least 8 percent of the human genome has changed since the departure from Africa. The new analysis has revealed five distinguishable races that evolved in response to regional conditions: Africans, East Asians, Caucasians, the natives of the Americas, and the peoples of Australia and Papua New Guinea. Yet social scientists go on denying the very existence of races.
The American Anthropological Association declares race to be “a human invention” that is “about culture, not biology.” The American Sociological Association calls race a “social construct.” Even biologists and geneticists are afraid of the R-word. More than 100 of them sent a letter to the New York Times denouncing Wade’s book as inaccurate, yet they refused to provide any examples of his mistakes. They apparently hadn’t bothered to read the book because they accused Wade of linking racial variations to IQ scores—a link that his book specifically rejected. Some genetic differences are politically acceptable on the left, such as the biological basis for homosexuality, which was deemed plausible by 70 percent of sociologists in a recent survey. But that same survey found that only 43 percent accepted a biological explanation for male-female differences in spatial skills and communication. How could the rest of the sociologists deny the role of biology? It was no coincidence that these doubters espoused the most extreme left-wing political views and the strongest commitment to a feminist perspective. To dedicated leftists and feminists, it doesn’t matter how much evidence of sexual differences is produced by developmental psychologists, primatologists, neuroscientists, and other researchers. Any disparity between the sexes—or, at least, any disparity unfavorable to women—must be blamed on discrimination and other cultural factors...
Over and over, scientists yielded to the temptation to exaggerate their expertise and moral authority, sometimes for horrendous purposes. Drawing on research into genetics and animal breeding from scientists at Harvard, Yale, Johns Hopkins, and other leading universities, the eugenics movement of the 1920s made plans for improving the human population. Professors taught eugenics to their students and worked with Croly and other progressives eager to breed a smarter society, including Theodore Roosevelt, Woodrow Wilson, and Margaret Sanger. Eventually, other scientists—notably, in England—exposed the shoddy research and assumptions of the eugenicists, but not before the involuntary sterilization or castration of more than 35,000 Americans. Even after Hitler used eugenics to justify killing millions, the Left didn’t lose its interest in controlling human breeding. Eugenicist thinking was revived by scientists convinced that the human species had exceeded the “carrying capacity” of its ecosystem. The most prominent was Paul Ehrlich, whose scientific specialty was the study of butterflies. Undeterred by his ignorance of agriculture and economics, he published confident predictions of imminent global famine in The Population Bomb (1968). Agricultural economists dismissed his ideas, but the press reverently quoted Ehrlich and other academics who claimed to have scientifically determined that the Earth was “overpopulated.” In the journal Science, ecologist Garrett Hardin argued that “freedom to breed will bring ruin to all.” Ehrlich, who, at one point, advocated supplying American helicopters and doctors to a proposed program of compulsory sterilization in India, joined with physicist John Holdren in arguing that the U.S. Constitution would permit population control, including limits on family size and forced abortions. Ehrlich and Holdren calmly analyzed the merits of various technologies, such as adding sterilants to public drinking water, and called for a “planetary regime” to control population and natural resources around the world...
Their ideas went nowhere in the United States, but they inspired one of the worst human rights violations of the twentieth century, in China: the one-child policy, resulting in coerced abortion and female infanticide. China struggles today with a dangerously small number of workers to support its aging population. The intellectual godfathers of this atrocity, had they been conservatives, surely would have been ostracized. But even after his predictions turned out to be wildly wrong, Ehrlich went on collecting honors...
For his part, Holdren has served for the past eight years as the science advisor to President Obama, a position from which he laments that Americans don’t take his warnings on climate change seriously. He doesn’t seem to realize that public skepticism has a lot to do with the dismal track record of himself and his fellow environmentalists. There’s always an apocalypse requiring the expansion of state power. The visions of global famine were followed by more failed predictions, such as an “age of scarcity” due to vanishing supplies of energy and natural resources and epidemics of cancer and infertility caused by synthetic chemicals. In a 1976 book, The Genesis Strategy, the climatologist Stephen Schneider advocated a new fourth branch of the federal government (with experts like himself serving 20-year terms) to deal with the imminent crisis of global cooling. He later switched to become a leader in the global-warming debate...
Environmental science has become so politicized that its myths endure even after they’ve been disproved. Rachel Carson’s Silent Spring set off decades of chemophobia with its scary anecdotes and bad science, like her baseless claim that DDT was causing cancer in humans and her vision of a mass avian die-off (the bird population was actually increasing as she wrote). Yet Silent Spring is taught in high school and college courses as a model of science writing, with no mention of the increased death tolls from malaria in countries that restricted DDT, or of other problems—like the spread of dengue and the Zika virus—exacerbated by needless fears of insecticides. Similarly, the Left’s zeal to find new reasons to regulate has led to pseudoscientific scaremongering about “Frankenfoods,” transfats, BPA in plastic, mobile phones, electronic cigarettes, power lines, fracking, and nuclear energy. The health establishment spent decades advocating a low-salt diet for everyone (and pressuring the food industry to reduce salt) without any proof that it prolonged lives. When researchers finally got around to doing small clinical trials, they found that the low-salt diet did not prolong lives. If anything, it was associated with higher mortality. The worst debacle in health science involved dietary fat, which became an official public enemy in the 1970s, thanks to a few self-promoting scientists and politically savvy activists who allied with Democrats in Congress led by George McGovern and Henry Waxman. The supposed link between high-fat diets and heart disease was based on cherry-picked epidemiology, but the federal government endorsed it by publishing formal “dietary goals for the United States” and creating the now-infamous food pyramid that encouraged Americans to replace fat in their diets with carbohydrates. The public-health establishment devoted its efforts and funding to demonstrating the benefits of low-fat diets. But the low-fat diet repeatedly flunked clinical trials, and the government’s encouragement of carbohydrates probably contributed to rising rates of obesity and diabetes, as journalists Gary Taubes and Nina Teicholz have chronicled in their books...
The dietary-fat debate is a case study in scientific groupthink—and in the Left’s techniques for enforcing political orthodoxy. From the start, prominent nutrition researchers disputed fat’s link to heart disease and criticized Washington for running a dietary experiment on the entire population. But they were dismissed as outliers who’d been corrupted by corporate money. At one hearing, Senator McGovern rebutted the skeptics by citing a survey showing that low-fat diet recommendations were endorsed by 92 percent of “the world’s leading doctors.” Federal bureaucrats and activists smeared skeptics by leaking information to the press about their consulting work with the food industry. One skeptic, Robert Olson of Washington University, protested that during his career, he had received $250,000 from the food industry versus more than $10 million from federal agencies, including ones promoting low-fat diets. If he could be bought, he said, it would be more accurate to call him “a tool of government.” As usual, though, the liberal press focused only on corporate money. These same sneer-and-smear techniques predominate in the debate over climate change...
Pesident Obama promotes his green agenda by announcing that “the debate is settled,” and he denounces “climate deniers” by claiming that 97 percent of scientists believe that global warming is dangerous. His statements are false. While the greenhouse effect is undeniably real, and while most scientists agree that there has been a rise in global temperatures caused in some part by human emissions of carbon dioxide, no one knows how much more warming will occur this century or whether it will be dangerous. How could the science be settled when there have been dozens of computer models of how carbon dioxide affects the climate? And when most of the models overestimated how much warming should have occurred by now?
These failed predictions, as well as recent research into the effects of water vapor on temperatures, have caused many scientists to lower their projections of future warming. Some “luke-warmists” suggest that future temperature increases will be relatively modest and prove to be a net benefit, at least in the short term. The long-term risks are certainly worth studying, but no matter whose predictions you trust, climate science provides no justification for Obama’s green agenda—or anyone else’s agenda. Even if it were somehow proved that high-end estimates for future global warming are accurate, that wouldn’t imply that Greens have the right practical solution for reducing carbon emissions—or that we even need to reduce those emissions. Policies for dealing with global warming vary according to political beliefs, economic assumptions, social priorities, and moral principles. Would regulating carbon dioxide stifle economic growth and give too much power to the state? Is it moral to impose sacrifices on poor people to keep temperatures a little cooler for their descendants, who will presumably be many times richer? Are there more important problems to address first? These aren’t questions with scientifically correct answers. Yet many climate researchers are passing off their political opinions as science, just as Obama does, and they’re even using that absurdly unscientific term “denier” as if they were priests guarding some eternal truth.
Science advances by continually challenging and testing hypotheses, but the modern Left has become obsessed with silencing heretics. In a letter to Attorney General Loretta Lynch last year, 20 climate scientists urged her to use federal racketeering laws to prosecute corporations and think tanks that have “deceived the American people about the risks of climate change.” Similar assaults on free speech are endorsed in the Democratic Party’s 2016 platform, which calls for prosecution of companies that make “misleading” statements about “the scientific reality of climate change.” A group of Democratic state attorneys general coordinated an assault on climate skeptics by subpoenaing records from fossil-fuel companies and free-market think tanks, supposedly as part of investigations to prosecute corporate fraud. Such prosecutions may go nowhere in court—they’re blatant violations of the First Amendment—but that’s not their purpose. By demanding a decade’s worth of e-mail and other records, the Democratic inquisitors and their scientist allies want to harass climate dissidents and intimidate their donors. Just as in the debate over dietary fat, these dissidents get smeared in the press as corporate shills—but once again, the money flows almost entirely the other way. "
