Further, he is using his personal story to argue for a specific range of treatment programmes (am I being fair, I suspect I am as though he does not always name programmes himself, he does lend his support to individuals and articles/events that do), none of which he actually undertook.
This emphasizes how morally and intellectually bankrupt the whole psychobehavioral project is. Ideologues have for decades 'tried' every possible variation and combination of modalities and approaches, treating them as if they all need to be independently checked (and then compared, then all summarized under a single generic label, showing how they know it's all pretend BS).
And yet when it comes down to it, all of them find no problem with just generally recommending any of them, doesn't matter what's in it, even based on a personal anecdote of someone who didn't even use any of those. The way Garner explains it, it's clearly a simple matter of belief. He says that first he believed he would not recover, then he did, and he recovered, even though by his own account he had been very active for months by then.
It's a completely generic approach where the details absolutely don't matter, but every imaginable combination of details has to be checked, ten times at a minimum, then twice more again, as long as it takes. Even though to them it literally doesn't matter, they couldn't care less whether someone faithfully applies the LP, or Gupta, or does mindful yoga, it's all just the generic idea of... some kind of fear avoidance / stress reduction, or whatever.
Every one of those, and they keep creating new ones, all identical to every other one, has to be checked for all possible combinations, individually and in group, in person or through an app, intensive or leisurely, focused on fitness or maybe enjoyment. But everyone involved in this truly doesn't care, worst case they'd advise to try them all, it's not as if it makes any difference. Some years ago Chalder even said that, that she doesn't care what helps someone, they're not just agnostic as to cause, they're completely agnostic as to the process itself, as people who create, sell and promote processes.
All of this is blatant fraud. They are stealing scarce research funding to do something they know is performative BS. They know it makes no difference, they all personally don't even care. But they'll keep going, will keep lying and stealing and harming, until the very last second, when the giant castle of cards they built just collapses from a simple whisper: "we found it, we found the cause, we know what happens".
