Although tests should stand by on their own, in practice, it *is* more
convincing if the theory behind it appears to be sound. For example, if
we can investigate the components of a system, and verify how they work,
there is more confidence if what we appear to measure is what we can
predict from the components. For example, we can measure electrical
properties of nerves. We can measure electrical properties of say, eye
light cones. We can then make predictions say, of colour response. If
one starts using words like "chi" and stuff like it, the only reasonable
conclusion is that its all made up. There is just way too much to take
on face value. Both the mechanism and the results of the claims just
come across as dubious. Its just one of those gut feels from experience.
Usually, when something is sound, sound reasons for the soundness pop
up.

How would you do a double-blind trial on a therapy like shiatsu?
Maybe. However, it might be convincing enough if enough tests were done.Double-blind means neither the doctor nor the patient know whether the
treatment being given is the correct one or a placebo. But shiatsu is
a hands-on therapy - like a form of massage but based on the
principles of chinese medicine. And to do it properly needs a long
period of training (at least 3 years) where the doctor learns how to
detect imbalances in chi using methods like feeling muscle tone in
various parts of the body (according to the chinese understanding
there's more to it than that, but I'll stick at that for the purpose
of argument), looking at skin colour, tone of voice etc. The
treatment consists of pressure point massage along the meridians,
stretching limbs in particular ways, and similar things.
There's no way that you could do this properly without knowing
whether or not you were doing it properly, if you see what I mean -
it wouldn't be enough to have an untrained person read a chart and do
the massages because they might not do it in the right way, and the
right treatment to apply would vary session by session anyhow.
This is quite different to a drug trial, where nurses can be given
drugs and apparently identical placebos in unmarked containers, and
then it's just a question of the patient swallowing one or the other.
The best you could do for something like this would be either a
single-blind trial where the practitioner deliberately applies an
irrelevant treatment to some of the patients, or a non-blind trial
where you compare with some other kind of treatment like a normal
massage. But if it was done like this, then people might reject the
results just because it's not double-blind.
Hard to say, just what might be considered reasonable in difficult test
situations.
Performing decent tests is always a problem. It is, in principle,The point being that it's easy to say 'I won't believe it until I've
seen a double-blind trial', without really thinking about what this
would mean for a treatment like shiatsu. Which is an example of the
point I'm arguing
- judging something like that by the standards of scientific
medicine, and expecting to be able to apply the same sort of tests
that are used there isn't necessarily going to be the best way to
find out whether it really works or not. It's not a case of special
pleading - saying it's not fair to apply those tests because they are
too harsh or something, it's because at least in this example, they
are simply not appropriate to the situation.
