Perhaps Goldacre could be reached by speaking the same language and using criticisms he has for drug studies. He may be interested in how the Science Media Centre portrayed the PACE Trial, a non-blinded study without placebo control, as the "highest grade of clinical evidence" on par with "drug intervention studies". He may also be interested in how the dubious claims of "normal range" in fatigue and physical function were confused for "recovery", not only in the news articles, but also by pro-CBT/GET authors commissioned to write a Lancet editorial on the PACE Trial.
However, I read that Goldacre is a fan of Wessely, whom was like a mentor to him during his formative years? So if true, I doubt Goldacre will be coming after the cognitive behavioural model and CBT/GET for CFS. Also, Goldacre appears to be a true believer in a powerful placebo effect, which may make him more tolerant of mind over body ideologies without applying adequate skepticism to them or examining alternative explanations for the evidence.
As Alex touched upon, skepticism is not about denial and speculative counter-claims, it is about doubt towards claims and a critical evaluation of the evidence. I have found that equal opportunity skepticism is rare. People naturally focus on their own interests and care less about criticizing their own beliefs. I do not expect Goldacre to give a flying toss about the questionable flaw-riddled research into ME/CFS if it involves criticizing a model which Wessely has helped to develop.
