A “Double Standard”?
Last week I had planned to write a comprehensive critique of a recent comment by Larry Dossey. He had posted it on Val Jones’s betterhealth website in response to Dr. Val’s essay, “The Decade’s Top 5 Threats To Science In Medicine,” originally posted here on SBM. Much of what Dr. Val had identified as the top threats involved recent dalliances, by government, medical schools, and the media, with the collection of implausible and mostly nonsensical health claims that advocates have dubbed “CAM.” As uncontroversial as Dr. Val’s assertions ought to have been—similar to suggesting that closing one’s eyes and “using the force” would be a threat to safe driving (even if some might quibble over the top threats to science in medicine)—Dr. Dossey demurred by distraction:
Your article implies that conventional medicine is grounded in evidence-based research and that CAM is not. This is grossly overstated, and suggests that a double standard is being applied to these fields.
Dossey trotted out familiar arguments: “Much, if not most, of contemporary medical practice still lacks a scientific foundation”; “the Congressional Office of Technology Assessment (OTA) found that only an estimated 10 to 20% of the techniques that physicians use are empirically proven”; hospital care is “the third leading cause of death in the United States,” accounting for hundreds of thousands of deaths each year.
He concluded with an appeal to fairness, rationality, and collegiality:
Overwhelming evidence reveals that conventional medicine is, on the whole, woefully unscientific. It’s fashionable and easy to deny this, but the facts say otherwise. So, by all means, Dr. Val, be critical of CAM – but do not fall into a double standard. Let us ruthlessly apply science to ALL we do as physicians. Let us challenge ALL areas of medicine to a higher standard. On that, I’m pretty sure we can agree.
Keep up the good work.

I procrastinated with my own rebuttal, and in the meantime David Gorski responded to similar language found in an article by Dossey (and two other magical thinkers) titled “The Mythology of Science-Based Medicine,” published by the Huffington Post. I’ll not repeat Dr. Gorski’s able rebuttal in any detail, and I’ve already written about much of what this matter brings to mind. Examples are here, here, and here on the perils of conflating science-based medicine and Evidence-Based Medicine (EBM); here on the false dichotomy of modern medicine vs. “CAM”; here on a concise definition of “CAM”; here and here on the mischief spawned by demands to “ruthlessly apply science,” in the narrow, EBM sense of the word, to implausible health claims; here (point #7) and here regarding the tu quoque fallacy, the “10-20% empirically proven” claim, and the risks of modern health care; here (scroll down to “this week’s entry”) and here, regarding some of Dossey’s own opinions about science and the future of medicine.
For now I’ll elaborate on a few points. These pertain not only to Dr. Dossey but also to myths common to the advocacy of pseudomedicine, so I hope to provide some useful information.
