Any guesses about which way the SMC is going to jump on this one? They, too, painted themselves into a corner with their almost hysterical support of the PACE (and related) studies. KCL has now put the SMC in the position of either coming down against basic scientific research principles or accepting egg on its face for having persistently reported extremely poor research in glowing terms. Neither is a place the SMC is going to like standing.
One possibility -- play the wide-eyed innocent and pretend they were completely taken in by people they had every reason to trust. This ignores the fact that, 1) they're supposed to be guardians of proper science reporting and so should have been looking out for such obvious abuses as this, and 2) they were warned repeatedly that there is something not right about this research and they chose to defend it vociferously anyway. Still, that might be the best option they have -- deflect responsibility and play the victim.
