The Science Media Centre should not be seen as authoritative science organisation -- or a serious organisation at all. It is one of the many supposedly neutral-sounding bodies that are the product of the degeneration and disintegration of a once left-wing organisation, the Revolutionary Communist Party (in Britain, no relation to the US-based group still running under that name) that gave up on itself some 20 years ago, and has since become a peculiar right-wing quasi-libertarian think-tank called Spiked On-Line. Why any proper scientists wish to be associated with it can only be ascribed to ignorance on their part or the desire to get their names at any cost into the media. Read more about them
here and
here: you will note how the same names keep reappearing from one organisation to another.
Following the methodology of the old political group, the SMC and all the other groups in and around Spiked like to be 'edgy' and 'controversial', and which usually means putting forward a line that -- very peculiarly -- usually ends up aligning with the most rapacious ends of big-business. Why SMC has decided to throw its lot in the Wesselyans on ME/CFS is, however, a bit of a mystery to me.
