But that doesn't make the old stuff a lie, it just replaces the knowledge you had with what's correct and that's absolutely fine.
"Experts" are ten a penny, actual experts are the ones you want to listen to, the people at the top of their field, the ones with certified backgrounds in their area of study.
Take Covid. Nobody, not even the media, took it seriously until it started killing people very quickly. There were a lot of scientists warning that this was incredibly dangerous. At that point, opinion should not have been split, nobody should have been calling it "the flu" and nobody should have been calling it a hoax. There should have been people taking that warning seriously. Instead, we've seen nearly 4,800,000 people die worldwide and many more suffer life changing side effects.
Was there a lot of scientific knowledge about Covid 19 in November 2019? No, there was not, but there very quickly was data and warnings were put out by people who knew what they were talking about, which were promptly ignored by non-scientific people who thought they knew better.
Now we have it with climate change. There is undeniable proof that human influence on climate change is real, yet there are still major celebrities and politicians who say it's all false. That shouldn't be happening, there shouldn't be a window for a scientific fact to go from the objective to the subjective, especially given the dangers the threat poses.
