If placebos were legitimate for subjective symptoms surely they would be even more legitimate for objective measures? If they worked.
Exactly. Subjective improvement must indirectly lead to objective improvement elsewhere.
Wessely himself said that
"in the later stages of treatment patients are encouraged to increase their activity (which must ultimately be the aim of any treatment)"
Wessely, David, Butler, & Chalder – 1990
Otherwise what is the point of simply priming patients to report temporary, modest, and practically meaningless gains on subjective measures? Especially for chronic conditions.
Even if ME was what Wessely claims it to be, then his treatments must still lead to patients improving and getting at least a fair chunk of their 'normal' lives back.
But those treatments clearly don't. So he has nothing. And he knows it.
Hence his endless revisionist sophistry.
I think it would be possible to come up with a clinical trial design that largely eliminates the problem of biased self-reporting.
Having this sort of design would allow them to safely experiment with all these various tricky ideas without risk of, bear with me, fooling themselves with false beliefs about the illness.
Ironically, that is (partly) what PACE originally was.
But they then either failed to collect relevant objective data (actimeter outcomes), or downplayed, misconstrued, or simply ignored the solid collective null result from the objective measures that they did collect.
This, more than anything, is where their sin lies. They refused to face up to what the evidence from their own "definitive" trial was clearly saying.
If they had said in the main PACE paper something like
'these treatments and this approach have not delivered what we had hoped for, their explanatory and therapeutic power is poor, and it is time to try something else', they probably would have got away with it. They might even have been considered good examples of honest scientists at work.
But they didn't. They chose instead to keep doubling down on their denial and advocacy, and their ruthless assault on the credibility and integrity of their critics.
So it is important to ensure his real history is not lost.
This.
