What hinders good research? Ego. Period. Simon Wessely is a good example. He has a belief - that Chronic Fatigue Syndrome is a neuropsychiatric condition. So why would he want to try and replicate the XMRV findings then - Ego. To reinforce his beliefs. How do you do this - answer: pervert the results. How do you pervert scientific findings - answer: break the rules that in order for a scientific study to be valid, you have to copy exactly. So he obtained negative results, further reinforcing his beliefs that CFS is not infectious.
But why the motive? In countries like the UK, much of the research is government funded, and the National Institute For Clinical Excellence (NICE) has a lot of control over what research goes on. In recent years, budgets have become increasingly constrained. In one of my previous posts, I mentioned about some findings on CFS that were suppressed - I directly challenge any UK bureaucrat who has access to any of these to post them on WIKILEAKS. Currently, the UK health care system has become increasingly under strain from high drug costs for biologics to treat anything from cancers, to psoriasis, rheumatoid arthritis, ankylosing spondylitis, multiple sclerosis, and Psoriasis. For them, treating CFS would mean another huge cost factor to expand coverage of HIV drugs to CFS patients, as well as perhaps Rituximab. As long as the neuropsychiatric psychobabble can drown out the voices of good science, it is a cost they do not have to face.
