Even when a claim is disproved, it hangs around like a deadbeat renter you cant evict. Years after the claim that vitamin E prevents heart disease had been overturned, half the scientific papers mentioning it cast it as true, Ioannidis found in 2007.

If the scientific community didn't herald every new discovery as THE answer to all health woes and the fountain of youth, then this wouldn't be a problem.
When that news broke, EVERYONE heard about it. When they decided the opposite and had to admit they were wrong, well, it just didn't get the publicity as when they claim they're right.
