Of SBM and EBM Redux. Part III: Parapsychology is the Role Model for “CAM” Research

This is the third post in this series*; please see Part II for a review. Part II offered several arguments against the assertion that it is a good idea to perform efficacy trials of medical claims that have been refuted by basic science or by other, pre-trial evidence. This post will add to those arguments, continuing to identify the inadequacies of the tools of Evidence-Based Medicine (EBM) as applied to such claims.

Prof. Simon Replies

Prior to the posting of Part II, statistician Steve Simon, whose views had been the impetus for this series, posted another article on his blog, responding to Part I of this series. He agreed with some of what both Dr. Gorski and I had written:

The blog post by Dr. Atwood points out a critical distinction between “biologically implausible” and “no known mechanism of action” and I must concede this point. There are certain therapies in CAM that take the claim of biological plausibility to an extreme. It’s not as if those therapies are just implausible. It is that those therapies must posit a mechanism that “would necessarily violate scientific principles that rest on far more solid ground than any number of equivocal, bias-and-error-prone clinical trials could hope to overturn.” Examples of such therapies are homeopathy, energy medicine, chiropractic subluxations, craniosacral rhythms, and coffee enemas.

The Science Based Medicine site would argue that randomized trials for these therapies are never justified. And it bothers Dr. Atwood when a systematic review from the Cochrane Collaboration states that no conclusions can be drawn about homeopathy as a treatment for asthma because of a lack of evidence from well conducted clinical trials. There’s plenty of evidence from basic physics and chemistry that can allow you to draw strong conclusions about whether homeopathy is an effective treatment for asthma. So the Cochrane Collaboration is ignoring this evidence, and worse still, is implicitly (and sometimes explicitly) calling for more research in this area.

On the other hand:

There are a host of issues worth discussing here, but let me limit myself for now to one very basic issue. Is any research justified for a therapy like homeopathy when basic physics and chemistry will provide more than enough evidence by itself to suggest that such research is futile(?) Worse still, the randomized trial is subject to numerous biases that can lead to erroneous conclusions.

I disagree for a variety of reasons.

Puncturing the Acupuncture Myth

Note: This is slightly revised from an article I originally wrote as a “SkepDoc” column for Skeptic magazine. It was pre-released online in eSkeptic and it has already generated a lot of comments, including “a truly amazing piece of peurile pseudo-intellectualism,” “an ad hominem attack on one form of alternative medicine so beset by poor thinking that one must come to the conclusion this woman might just be paid to write such propaganda,” and “twaddle wrapped in swaddling rhetoric.” (I treasure comments like those as evidence that my critics are so bankrupt of real arguments that they have to dip into the insult pouch for ammunition.)  I thought it would be interesting to post it here on the blog and see how much controversy it would stir up among my co-bloggers and readers.  Please keep in mind that it was written for a popular audience and excuse the lack of scholarly citations. You may recognize some of the studies I refer to from previous blog entries.


“Alternative” medicine is by definition medicine that has not been scientifically proven and has not been accepted into mainstream scientific medicine. The question I keep hearing is, “But what about acupuncture? It’s been proven to work, it’s supported by lots of good research, more and more doctors are using it, and insurance companies even pay for it.”

It’s time the acupuncture myth was punctured – preferably with an acupuncture needle. Almost everything you’ve heard about acupuncture is wrong. (more…)
