The only thing that "The Neuroscience" shows is that the brain can do some cool things we wouldn't initially expect. It categorically does not show that the brain does do X or Y cool thing in any other context. Simply the possibility of something occurring is poor evidence that it actually is occurring.
And to this point, many such as yourself might point to some patient testimonies, or some small gains in clinical trials, to show that their success is retroactive proof that the theory actually is true. To that I would say: it really, really isn't proof.
If your theory relies on the fact that someone's perception and interpretation of their own bodily state cannot be trusted at face value when they are sick,
you simply cannot claim that their perception and interpretation of their body after the treatment is proof of its correctness and effectiveness. You're quite literally saying that you can't trust the patient when they say it won't/doesn't work, but you should trust the patient when they say it does work.
That's why, as many have argued across different threads, a subjective outcome measure will never be effective proof that the treatments work.
@dundrum I can understand why you say that you need to use subjective measures when nothing else exists, but the nature of any cognitive restructuring technique is such that it inherently invalidates their use. I really really hope you can understand that.
Even if we could prove that these therapies "actually work" by an objective measure, it's not proof that the underlying theory is true. You said yourself
@Friendswithme that there are many examples of severe pwME "relapsing" over and over again after somaticisation techniques. In fact, many pwME report similar patterns from things like supplements and off-label medications. Just because a biological mechanism enables you to somehow push through what is wrong for a short period of time does
not mean it's reversing the original problem.
What you might be observing in these situations is a very effective mobilization of some backup mechanism that can compensate for whatever is actually wrong for a short period of time. But the fact that relapses keep happening would then be evidence that this backup mechanism cannot be employed long term, and you simply don't know what the risks are of continuing to employ it. And again, because of lack of actual evidence, wild speculations are all that can be done here.
That's why many of us can never get behind a therapy that literally requires gaslighting patients to distrust their own perceptions. If it's:
1) not proven that you're actually right, and
2) you have no way to make sure they're being effectively "deprogrammed" after giving it an honest go, and
3) there's no way to make sure that there is no consequence of failing to get better from this method (wasted money, being disbelieved by family and medical professionals, pushing themselves so much their baseline condition permanently worsens etc.),
then the harms of continuing to push this method as an effective treatment are very substantial!
