I just want to be very clear about this: You are saying that the explanation for every single person who has experienced sustained remission with any intervention that failed a double-blinded trial (so basically all of them), or with mind-body therapies...all of these, because placebos don't work and neither do interventions that fail in trials...all of these people are experiencing coincidental-with-treatment spontaneous long-lasting natural remissions? All of them? So many long-lasting natural coincidental remissions, in all these case control trials, in the placebo arm of blinded trials, in all these anecdotes, but that's what they must be, because no therapy has worked in a blinded trial and placebos don't work either? I mean, this might be the beating heart of our disagreement right here. To me, that position is outlandish. I think the more likely explanation is that at least a subset of people have symptoms that respond well, long-term, to something that was happening with the intervention that sparked their remission/recovery. If we can identify them, then we've got a subset who will respond well to an intervention that exists already. And that is medical progress. Edit: And if the treatment they responded well to is a pharmaceutical that doesn't work in a blinded trial, then we know even more about what they are responding to.
