I sent this recently to the "rapid response" section of the BMJ. It was in response to a disussion
of homeopathy, which is still attracting precious medical research funds (God knows why). Exactly
the same considerations apply to many other "alternative" treatment theories.
Quote (slightly altered)
"Time to rephrase the questions"
Evidence that homeopathic remedies possess intrinsic biomedical properties is actually weakening.
Even after two hundred years the several extraordinary hypotheses upon which it is based remain
quite unvalidated (where on earth else in medicine does a "like cures like" principle apply?).
It is surely time to forget the "weird science" aspect of it altogether.
It is, after all, only one of many improbable treatment methods competing for our interest, all with
fairly similar levels of evidence or lack thereof. They are all sustained mainly by simplistic (and
too self-serving?) interpretations of outcomes within the clutter of influences that apply within
everyday medical practice.
It would be easier to take such contenders seriously if there were not altogether too many "weird
sciences" involved, far too many for science to have overlooked in the year 2003, and also if novel
conventional medical methods were not producing equally staunch believers until dummy treatments
were shown to be capable of producing equivalent "responses"(e.g. 1).
The questions, rephrased, are "why can absolutely ANY kind of well- intended medical attention lead
to apparent clinical benefits, what are the limitations of such non-specific effects (we already
have a fairly good handle on that) and what might be the ethics of using pseudoscientific pretences
as a therapeutic method (once this penny finally drops, as it must eventually for most)."
