There is a tendency for real doctors with backing from Academia or whoever's in charge of deciding how you science to just plain getting it wrong and not realizing it for a long time.
Homeopathy is a good example of this, as it appeared to get great results when it was created during the Bubonic Plague and had such staying power to the point that in the 1800's it was considered a legitimate and mainstream field of medical practice.
Now today we know Homeopathy is nonsense... Remembers New Age Healing is still a thing Okay, those of us with sense know homeopathy is garbage. With the only reason it was getting such wonderful results was because the state of medicine for a long period of time in human history was so god awful that not getting any treatment at all was actually the smarter idea. Since Homeopathy is basically just "No medicine at all", that's exactly what was happening with its success.
Incidentally this is also why the Christian Science movement (Which was neither Christian nor Science) had so many people behind it, people were genuinely living longer from it because it required people to stop smoking at a time when no one knew smoking killed you.
Anyhow. With that in mind, I want to know if there's a case where the exact opposite happened.
Where Scientists got together on a subject, said "Wow, only an idiot would believe this. This clearly does not work, can not work, and is totally impossible."
Only for someone to turn around, throw down research proving that there was no pseudo in this proposed pseudoscience with their finest "Ya know I had to do it 'em" face.
The closest I can think of is how people believed that Germ Theory, the idea that tiny invisible creatures were making us all sick, were the ramblings of a mad man. But that was more a refusal to look at evidence, not having evidence that said "No" that was replaced by better evidence that said "Disregard that, the answer is actually Yes"
Can anyone who sciences for a living instead of merely reading science articles as a hobby and understanding basically only a quarter of them at best tell me if something like that has happened?
Thank you, have a nice day.
She did, she had a history of lying and hypochondria, and gaslighting herself into believing her own lies because of the hypochondria.
She started suspecting she had powers after she believed she had cured her own paralysis...
The doctor who treated her would review his case files for biographers, and revealed he never believed her to be in critical injury nor even implied that she had any kind of paralysis. What really happened is her own hysteria caused her to blatantly misinterpret everything he said in the worst way possible.
The only reason she had as many followers as she did was because her system actually was helpful. Not because she had powers or anything, but at the time hers was one of the only movements that barred people from smoking, something that people believed was not only harmless, but healthy for you. So people actually were seeing notable improvements in their health and longevity... because they stopped smoking, not because they had magic powers.
There was also the not allowing people to go to the doctor at a time where the doctor was more likely to kill you than your disease.
As Medical Science got better, Christian Science became less helpful and more detrimental.
People really were seeing miracles, Mark Twain even directly stated that Christian Science would one day be bigger than the Roman Empire because of what it was doing for people....
But no one realized it was from abstaining from tobacco
