This confirmed my long-held belief that many people would rather be seen to be right than to get well.
I mostly agree, but I think it's just that: it's very hard to change a strongly held belief. Saying they'd rather be right than get well is a bit victim blaming.
It's more that they don't believe it will heal them. I've had people tell me I should accept Christ and pray more because in this realm that's the only thing that can really heal. I haven't so,, but not because I'd rather be right than healthy; it's because I don't believe it would help me. Maybe I'm wrong.
That's why I just prefer stuff that says, "Hey, worked for me - might not work for you." As soon as promises go beyond that, it gets quite aggravating. Like all the doctors who promise to heal us, then get annoyed with us if we don't get better with their wonderful care.
I don't think I have a ton of strongly held beliefs. I try to have a lot of well formed beliefs, lightly held. If we find out tomorrow that ME/CFS is not a distinct illness but is a bucket of five illnesses, I'm fine with that.
As for DNRS - what you said about kidney disease is one of the things that bothers me about those programs. None of them offer to treat any illness where there's a clear biomarker or even a widely accepted illness diagnosis. They don't offer to cure HIV, CKD, ALS, MD, even MS, etc.
In the end, I actually don't really care. If some people benefit, that's fine. If they benefit from prayer, that's fine. I'm relatively open minded and I tried Gupta for months following their instructions not to tell anyone (a smidge cult-like), repeat their mantras, etc. I found the mantras vaguely pleasant, found the videos horribly boring and annoying use of energy, and that was about it. Made zero impact on my health that I could tell.
To each their own, until we find reliable treatments for the majority.
