Hostility towards scientific consensus: A red flag identifying a crank or quack


I have yet another grant deadline to deal with, this time for the Department of Defense Congressionally Directed Medical Research Programs, this time around its Breast Cancer Research Program. Unfortunately, that put a high degree of time pressure on me. Fortunately, there’s still stuff in the archives of my not-so-secret other blog that I deem quite appropriate for this blog and that can be updated with minimal effort. If you don’t know what I’m talking about when I refer to my not-so-secret other blog, then it’ll definitely be new to you. If you haven’t been reading that blog for at least four and a half years, it’ll be new to you as well. And even if you have seen it before, I think it’s worth revisiting.

Why? It came up because of an encounter I had on Twitter with Jane Orient, MD, who, as you might recall, is the executive director of the American Association of Physicians and Surgeons (AAPS). I’ve written about the AAPS before. You can get the details in the link, but if you don’t have time suffice to say that it is an entire organization of libertarian-leaning “brave maverick doctors” who think Medicare is unconstitutional, don’t believe that the government should have much, if anything, to do with regulating the practice of medicine, and reject evidence-based guidelines as an unholy affront to the independence of the physician. Along the way, the AAPS, through its journal, The Journal of American Association of Physicians and Surgeons (often abbreviated JPANDS), promoted antivaccine views, including the discredited concept that vaccines cause sudden infant death syndrome, HIV/AIDS denialism, and the scientifically unsupported idea that abortion causes breast cancer (a topic I might have to revisit, given the activity promoting it recently).

In any case, two or three weeks ago, I was having a bit of an exchange with Dr. Orient over anthropogenic global climate change (often abbreviated as AGW, for anthropogenic global warming, for short), the well-accepted science that concludes that CO2 generated by human activity is having a serious warming effect on the earth’s climate. As you might expect, she’s not big on this particular scientific consensus. I forgot about it, but then the other day saw this Tweet exchange between Dr. Orient and Ed Wiebe:

An open letter to Penn & Teller about their appearance on The Dr. Oz Show

An open letter to Penn & Teller about their appearance on <em>The Dr. Oz Show</em>


Dear Penn & Teller,

I really don’t want to say this, but I feel obligated to. I’m afraid you screwed up. Big time. (Of course, if this weren’t a generally family-friendly blog, where we rarely go beyond PG-13 language, I’d use a term more like one that Penn would use to describe a massive fail, which, as you might guess, also starts with the letter “f”; I think he’d appreciate that.)

I’m referring, of course, to your appearance on The Dr. Oz Show one week ago (video: part 1, part 2, part 3, part 4). Before I begin the criticism, let me just take care of the obligatory but honest statement that I am a fan. I’ve been a fan for a long time. Indeed, I remember seeing you guys perform in Chicago back in the late 1990s when I was doing my fellowship at the University of Chicago. I’ve also seen you in Las Vegas a couple of times, most recently a couple of years ago (see pictures below) at TAM. The two of you have become skeptical icons, through your association with James Randi and over the last several years through your Showtime series Bullshit!, which is advertised with the tagline, “Sacred cows get slaughtered here.” And so they did for the eight seasons Bullshit! was on TV. When you guys were on, it was a thing of beauty to behold, both from the standpoint of entertainment and skepticism.

“Motivated reasoning,” alternative medicine, and the anti-vaccine movement

One theme that we at Science-Based Medicine keep revisiting again and again is not so much a question of the science behind medical therapies (although we do discuss that issue arguably more than any other) but rather a question of why. Why is it that so many people cling so tenaciously to pseudoscience, quackery, and, frequently, conspiracy theories used by believers to justify why various pseudoscience and quackery are rejected by mainstream science and medicine? Certainly, I’ve touched on this issue before on several occasions, for example, with respect to the anti-vaccine movement, the claim that abortion causes breast cancer, and how we as humans crave certainty.

It turns out that science and science-based medicine are hard for humans to accept because they often conflict with what our senses perceive and brains interpret as irrefutable evidence. The pattern-seeking function of our brain, when evaluating questions of causation in medicine, frequently betrays us. For instance, when a parent sees her child regress into autism sometime not long after being vaccinated, the easiest, most instinctive, and most emotionally compelling conclusion is that the vaccine must have had something to do with it. When scientists tell her that, no, in large studies looking at hundreds of thousands of children, there is no good evidence that vaccination confers an increased risk of autism and a lot of evidence that it does not, it’s a very hard message to believe, because it goes against how the parent interprets what she’s seen with her own eyes. Indeed, how often have we seen believers in the vaccine-autism link pour derision on the concept that when something like autistic regression happens in close temporal proximity to vaccination that the correlation does not necessarily equal causation? Similarly, believers in “alternative medicine” who experience improvement in their symptoms also pour derision on the observation, explained so well by R. Barker Bausell in Snake Oil Science, that people frequently take remedies when their symptoms are at their worst, leading them to attribute natural regression to the mean to whatever nostrum they started taking at the time.

These issues have come to the fore again, thanks to an article by an acquaintance of mine, Chris Mooney, author of The Republican War on Science, Storm World: Hurricanes, Politics, and the Battle Over Global Warming, and Unscientific America: How Scientific Illiteracy Threatens our Future (co-authored with Sheril Kirshenbaum). The article appeared in a recent issue of Mother Jones and was entitled, rather ironically, The Science of Why We Don’t Believe Science. Chris made his name as an author primarily in writing about the science of anthropogenic global warming and the political battles over policies intended to mitigate it and, to a lesser extent, over creationism and evolution denial. Of late he has written about the anti-vaccine movement as an anti-science movement, leading predictably to his being attacked by the likes of J.B. Handley as viciously as I and others have. Also of note, although he was widely praised for The Republican War on Science and Storm World, Mooney has been widely criticized in some circles for being too critical of “new atheists” and for lack of substance. In his current article, he discusses some of the science thus far about why people can cling to beliefs that science doesn’t just cast doubt upon but shows convincingly are totally wrong.
