In recent years, we’ve seen more of a marriage between science and public policy. Scientific results are turned into goverment mandates, all for the Greater Good. “The science is settled!!” the Wise thunder from the mountaintop, and us serfs have nothing left but to obey.
However, the history of science in government is pretty horrible. Some good comes out of it, for sure, but the negatives must surely outweigh the positives. Before we get into some pretty nasty examples, we should understand the reasons why.
The act of governing is a political act, that uses political processes – compromise, favor-trading (“log-rolling”), rhetoric, voting, concensus-building, etc. Science is, or at least should be, absolutely nothing like that. Einstein’s theory of relativity isn’t accepted because people traded support for it in return for Einstein’s support for, say, the Germ Theory of disease. Physicists didn’t vote for relativity. Instead, relativity stood the test of time, explaining the data better than any alternate theory. As a counter-example, let’s look at how the goverment’s stance that eating cholesterol causes heart disease started. The evidence was contradictory and weak, and there was a lot of disagreement among scientists. So they held a vote! If I remember properly, the original vote was something like 6-5. Once enshrined as government policy, research into alternative explanations was defunded, disagreeing voices were silenced (after all, you have to stay “on message”), and the public was hoodwinked into thinking “the science is settled.” Now, it’s accepted that eating cholesterol has nothing to do with heart disease. Whoops, sorry about that.
In politics, once the decision is made, everyone is expected to put aside previous allegiences and fall in behind the decision. Indeed, if lots of people continue to criticize the decision and propose alternatives, the populace would be confused and little progress could be made. In science, the exact opposite is true. When a new theory is put up, it is the duty of everyone to criticize it mercilessly – try to find all the observed phenomena and data that the theory cannot explain. It is these divergences that are key. If the theory can’t adapt elegantly to these gaps, it eventually dies and is replaced by something closer to the truth.
However, when dealing with science that has been infected with public policy, where politicial processes are applied to science, the opposite occurs. Naysayers are demonized. They lose tenure. They are vilified in the press. Their reputations are slandered. They are called “baby killers”, “nazis”, “heretics”, on and on – this kind of ad hominem attack has absolutely no place in a scientific discussion. Many great scientists have had awful personalities, and repugnant political views. This does not invalidate their ideas or their theories. Science should be, must be, impersonal.
It should be acknowledged that in the real world, science is indeed political. The “elders” who control the conferences, journals, and tenure approvals are unlikely to enthusiastically approve grants and promotions for some young upstart who is contradicting the very theories that they built their lives and reputations on. This is why Niels Bohr once said “Science progresses one funeral at a time.” When goverment gets involved, the crushing of dissent rises to a new level, having the force of law behind it.
Why does all this happen? An analysis using the branch of economics known as “public choice theory” from the book Beyond Politics gives a glimpse. Here the author is talking about climate change, but substitute your own favorite branch of science:
A public choice analysis of climate change politics predicts that the necessities of electoral politics will drive the climate change policy debate on the national level. Beaurocrats will use the process to increase budgets and influence, interest groups will seek political rents and use the process to pursue ideological committments having nothing to do with climate, voters will remain generally uninformed but sympathetic to “doing something,” and entrepreneurial politicians will maximize their chances of re-election by catering to both bureaucrats and special interests. It would be suprising if the process operated in any other way.
So climatologists, who otherwise would toil in relative obscurity, become rock stars (they are, after all, saving the world), and they get interviewed on TV, have their budgets increased tremendously, get tenure, and get a seat at the Big Table. Bureaucrats of the newly-formed Department of Saving the Climate get huge budgets (to dump iron sulfate or whatever in the atmosphere) and staffs, job security, and a seat at the Big Table. NGOs get validated, and since their expertise is needed, they get government funding and a seat at the Big Table. If it turns out the theory is wrong, it is in the interests of nobody to admit it (government agencies never want to admit they were wrong, because then they lose their authority with the public), and it is in the interests of everyone to pound their fists and proclaim “the science is settled!” and persecute the slobs with offending beliefs.
An excellent discussion of why science cannot solve public policy problems is discussed in this piece that explains that not supporting public climate change policy does not make you a “denier”. “Believing” in climate change, and endorsing specific public policies meant to hopefully address it, are two orthogonal things.
For a great discussion of how this works with a particular example (government advice on nutrition), listen to this really thought-provoking interview with Gary Taubes , someone who has studied this problem in detail for years. He talks about how bad policy gets created, the law of unintended consequences, and the built-in reluctance to admit mistakes and inherent bias toward group-think that government bureaucracies inevitably display.
Another big problem is that science often has been, and is, wrong. To create public policy based on “current science” can be disastrous if it turns out the science was wrong or incomplete, because public policy is incredibly hard to change and the government absolutely hates to admit it’s wrong.
Now let’s look at a couple examples.
Medicine
This is probably where the collusion between government and “science” does the most harm. In Europe, for example, goverment-sanctioned guidelines led to the deaths of around 800,000 people. You can read it here and here. I wonder what would happen if General Electric killed 800,000 people? Think there would be an outcry? But if Big Medicine (which is created, licensed, regulated, funded, protected and empowered by government so much that it might as well be the Department of Medicine) kills that many, no one really bats an eyelid.
The government decides what treatments are to be reimbursed, and what treatments are to be illegal, all on the advice of pharmaceutical lobbyists and doctors’ associations, even though medical practice is hopelessly out-of-date with research . In Australia, they even went so far as to pass a law that basically outlaws
The publication and/or dissemination of false or misleading health related information that may cause general community distrust of, or anxiety toward, accepted medical practice.
In other words, Australia has outlawed the free and open discussion of objective scientific results – IOW, they have outlawed the scientific method (I realize it says “false” information – but who decides if it’s false, especially before it’s been published and discussed!!). (This happened, by the way, when a journalist decided to write an article on statins, and went and read the original scientific publications rather than the press releases, and was completely underwhelmed by the results). This is a huge giveaway to Big Pharma: once you can get a treatment, by hook or by crook, to be “accepted” according to some “expert witnesses”, it’s now basically illegal to criticise it. The priests who threw Galileo in jail would feel right at home in modern day society.
Nutrition
The government started recommending low-fat diets in the mid-20th century, and at the end of the 1970s created concrete guidelines on nutrition (again, listen to the Gary Taubes interview for details) (through the farm bill, the government also subsidizes overproduction of selected commoditites). Massive shifts in the diet of Americans ensued, leading directly to the obesity epidemic. The government recommended trans-fat based margarine over butter or other fats, and recommended reducing cholesterol in the diet. Recently, however, cholesterol has been removed as a “nutrient of concern” from almost every government’s list (the US was one of the last). New York recently banned trans-fat, and deaths from heart attacks and strokes have declined dramatically. Now, the first evidence against trans-fat was discovered in the 1960s by Dr. Fred Kummerow, and Dr. Mary Enig did extensive research in the 70s and 80s (Dr. Kummerow was ignored; Dr. Enig was villified). A mere 60 years after the first evidence against trans-fats was published, the FDA sprung into action (after all, they are protecting our health, right?) and instituted a voluntary partial ban on trans-fat to provisionally start in a couple years. The ban was so toothless that the Grocery Manufacturers Association (basically the defenders of junk food) sent a letter to it’s members stating “nothing had changed” with the FDA’s action (or rather, non-action). Given the rate of reduction of disease in New York, if it’s really due to the removal of trans-fat (and that conclusion is not “settled”), this means that the goverment’s advice likely killed tens of millions of people over the last half-century. I wonder if we are going to get a “sorry” note? (How many people must die, do you think, before we get an apology? A hundred million not enough for you?) More likely, the people who try to write about and publicize this scandal will be crushed.
Climate Change
Personally, I really don’t know to what extent climate change is caused by humans, and I’m not here to debate that. But you can hear what happens if you dare challenge the consensus here. If you wonder who could want to crush scientific truth, ask yourself who would be the losers if tomorrow a study came out that completely debunking the entire narrative around global warming. They have the most incentive to keep the narrative going, and therefore the money flowing. This is a classic example of using negotiating, voting, and compromise to create a “scientific consensus” and the evil that comes from that. And you can hear what happens to people who dare to say “I don’t think this is quite correct.”
Don’t Trust the Experts
A bizarre outcome of all this is that you should not trust “experts” who interpret and summarize scientific fields of study. Almost all of them belong to organizations that have strong conflicts of interest. For example, in medicine:
It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgement of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of The New England Journal of Medicine. – Dr. Marcia Angell.
And she’s not the only one:
Journals have devolved into information laundering operations for the pharmaceutical industry… science has taken a turn towards darkness – Richard Horton, Lancet editor.
and of course
The medical profession is being bought by the pharmaceutical industry, not only in terms of the practice of medicine, but also in terms of teaching and research. The academic institutions of this country are allowing themselves to be the paid agents of the pharmaceutical industry. I think it’s disgraceful. – Arnold Seymour Relman, Harvard Professor of Medicine and Former Editor-in-Chief of the New England Medical Journal
You can read about how the research literature is co-opted and how the data is twisted. And that’s only medicine. Other fields are similarly corrupted. And the more money involved and/or the closer to government it is, the more corrupted it is.
To have a chance of understanding, you need to go back to the original research literature. Of course, that’s very time-consuming, so the next best bet is to find someone without conflicts of interest doing it out of their own interest. It’s hard, but you can’t trust organizations or institutions. You need to find indivuals that you respect.
Summary
The closer we get to human behavior, the dicier this romance between public policy and science gets. For example, suppose someone published some research showing that straight couples are happier than gay couples. Would the goverment then be justified in forceably breaking up gay couples and demanding that they “go straight”? After all, the science is settled, so if you answered no, you are obviously an anti-science zealot.
Just remember, “the science is settled” is code for “this is the political consensus, and we are set to make a ton of money off of this. If you value your career, get with the program.”
You can hear more about fake science driving public policy, and more of the risks for public policy.
Basically, anytime anyone says “I know how you should live better than you do, and you’d better listen to me because I’m smarter than you, and not only that I’ll have you crushed if you don’t obey” you should run the other direction.
