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)."
