This gotcha stuff is just nasty deceitful tricks, with no legitimate basis. The 'professionals' who devise and administer this drivel this should be ashamed of themselves for abusing their training and authority like this.
The part that bothers me the most, and I never see this addressed in the literature, is how misusing invalid 'gotchas' invalidates the otherwise valid ones. Saying scientifically valid things from the same position of authority where one says made up ones doesn't make the invalid things better, it only discredits the valid things, and the entire claim to legitimate expertise.
Which is something we do see out there. Once you are lied to your face by a health care professional, and it only takes one time, you never trust them implicitly again. This is one reason why conspiracy fantasies are so popular: the discrediting by official sources of their own credibility. They do have to be perfect, and it's hard, but this isn't even trying to be perfect, it's blatantly abusing the credibility of legitimate things to push through arbitrary politics.
Surely, there must be some of those that are legitimate. Maybe even universally so. That is, they will not be misapplied in situations where the conditions needed for this to be a gotcha aren't met. And yet, how do we know? Because they keep using completely fake gotchas, and misapplying real ones in cases where the conditions aren't even met, such as the EEfRT test at the NIH intramural study.
This reminds me of the so-called tests for FND - there's probably that same desire for the 'gotcha' moment.
We've seen this routinely misapplied by the very researchers who built this evidence base, who insist that those "rule in" signs are credible and necessary, yet aren't bothered when they aren't found. Again, same as the dude who invented the EEfRT thing, who made being able to perform either difficulty of the test a strict requirement, but is fine with this condition not being met, likely because he doesn't believe that ME/CFS is such a limitation, which is both arbitrary and wrong.
In the end much of this isn't any different than rejecting someone because you don't like their face, or their gender, or their religion, or their clothes, or literally any other arbitrary thing.
The real expertise, if it exists, which we can't know, because their tools also stamp as valid things that clearly aren't, becomes mixed with fake pseudoscience, where the latter is asserted to be just as valid by borrowing legitimacy from the valid things, if they even really are valid. Not only can't we know whether any of this is valid, neither can they.
Which is so much worse. It then becomes the same kind of problem where people start knowingly lying to get in power, all aware that what they say are lies, but with enough time, people who have been brought up in those lies end up believing the lies, unaware that they were lies in the first place, thus losing control over the entire thing.
This ends justify the means approach only ever has one outcome: the means become the ends. Lying to achieve an outcome almost never achieves that outcome, but it does make lying an accepted norm, which is exactly what we have seen out of psychobehavioral ideology and "Imagine a world"-based medicine.
