I agree more negative studies won't help us, but also it won't help to make enemies out of capable researchers, give a bad impression of the ME/CFS population and have no studies done at all. We need as many good studies as possible.
More methodologically flawed negative studies, will not help this community. You, community members, may have to 'make enemies' out of researchers (who may or may not be capable), if they are trying to use your blood in ways that damage scientific progress, and you don't let them, or you call foul. But your alternative is to follow like lambs to the slaughter of that scientific progress.
No studies, ironically, IS better than bad studies. But GOOD rigourous, honest studies are what is needed. No-one here should be settling for anything else. By raising the objections it has recently, this community might just be sending out the right message- that it is not here to be played any more, after years of being played/shafted (whatever term denoting exploited and abused you like) by the 'scientists'.
