I don't personally view Professor Crawley's involvement in the study as a cause for concern, irrespective of disagreement with some of her treatment recommendations for CFS. She would be one of a large group of scientists in MEGA who are all aiming to find the causes of M.E. based on replicable biomedical research, and I think she could contribute a lot of useful information on M.E. that many of the other scientists may not be aware of e.g. she has written interesting articles on CFS phenotypes in adults and children, has had a good article in the New Scientist recently and her colleague Dr. Hammond has had an excellent article in Private Eye.
From reading your post it seems to me that you take whatever is said by the BPS crowd at face value. I think that is a mistake.
Esther Crawley knows very well that if she had said what Hammond said that very few would believe her. But we have less knowledge of Hammonds opinions on ME so that the BPS crowd can get him to write something that sounds somewhat reasonable on the face of it on their behalf to bolster their credibility. They may not like having to allow for the concessions made regarding the illness but they are desperate and they are staring at the abyss of irrelevance while other researchers do real work. PACE has failed. So now they impose on their colleague Hammond to present a reasonable front in an attempt to calm any concerns that BPS bias will affect the MEGA research.
They lie.
Do not be fooled. The funding, should they get it will only be first stage funding. It will cover the cost of acquiring samples and the questionnaires EC will administer. Their is no guarantee of further funding.
Perhaps we might stop to ask the question: why the turnabout in the UK to a biomedical model just as PACE has failed. Is it because those at the CMRC recognise that the BPS model is incorrect or because they need to make a desperate attempt to control the narrative through pretense of biomedical research to maintain outward public credibility to those who don't look too hard at their methods?
They also need to do this now because they know that others elsewhere are getting close to an understanding of this disease and how to treat it. They can ignore all that research so long as they can say that they have something similar in the pipeline. They must simply await the results of their own research (then drag it out).
Nothing has changed. BPS are still in charge and they report to political bureaucrats in the NHS and elsewhere. There is a bigger context here than MEGA being an isolated piece of research. The treatment of people with ME in the UK reflects a larger agenda of treatment of disabled and unemployed people.
