Can someone with a scientific background explain to me what the distinction is (if there is one) between what Wessely admitted (in the bolded section above) and scientific fraud? Because Wessely's admission that the PACE team changed their recovery criteria so that they could claim their preferred treatments were 'moderately effective' rather than completely ineffective doesn't seem that far away from an acknowledgement that they falsified their results. But I'm not a scientist, so it's quite possible I've misunderstood how falsification is defined...
Because 'scientific fraud' is not a thing, in any other than the most obvious cases of data falsification.
I note again that Andrew Wakefield despite his paper reasonably arguably causing close on ten thousand deaths, and having much worse errors in the data collection and interpretation has faced no charges.
The problem here is that what they did was approved (apparently) by the various people with oversight.
They did not take the reported figures and lie about them, or alter them.
They apparently went to the supervising bodies and got approval for their new analysis plan.
What they did was (assuming for the moment they believed in their study) not fraudulent.
The fact that they did in fact get approval (assuming no collusion or undue influence) serves to insulate them from nearly all possible consequences other than the retraction of the paper(s) and possibly loss of medical licence.
We might wish that there was a criminal offence of publishing inaccurate science while being reckless or worse as to its effect on patients.
There isn't.
And any such offence is likely to only cover doing things and not revealing them to your supervisory body.
To make a financial analogy.
This is not a case of a banker stealing money from old peoples inactive bank accounts.
It's a case of them changing the terms and conditions of the accounts in order to make accounts that have been idle fee-charging, and going to the relevant authorities to confirm that they can do this with no notice, and those authorities agreeing.
The overall result may have been to create a paper which mislead most who read it, but they announced all of these flawed things first and underwent the peer review process.
