Here is a controversial one: there is no scientific “fact”.
Science has been so successful that scientists have forgotten that their method doesn’t unearth truths, but models.
This is very annoying in astro physics. If you visit a planetarium, they’ll tell you all about dark energy as an absolutely certainty of the universe without ever mentioning that it’s a giant thorn in the butt of physics. No one will tell you: “hey remember that 9th planet we told you about in school, yeah that’s not a thing anymore!”
Obviously there are things in the models that work perfectly, so you could say that it’s a fact that people with three chromosome 21 have dawn syndrome.
But overall few scientific models work as well as genetics, and even there, discoveries in epigenetics seem to make things not as black or white as we used to think.
My opinion is that the current distrust in science comes from the extreme cockiness of some scientists (and stupidity of science journalism), just imposing their views by stating “it’s been scientifically proven”, when they actually mean: “it’s not been scientifically disproved”.
The rna-based vaccination is a great example. The fact is that no one knows the long term effects of an rna-based vaccination. People are fairly confident that there are none, but there is no proof whatsoever that this is safe long term (disclaimer I think it is safe and I am vaccinated).
While Rna-based vaccination is a gigantic achievement stemming from decades of immense progress in molecular biology, it is an insult to intelligence to tell people that it is safe.
Anyways, just my thoughts…
