Yeah but you're basically describing ideologues here. This is how the vast majority of political activists approach the world where, last time I checked, parties even pretending to do things by scientific consensus are rare and they tend to not, in reality, refer to much science.
> If you look at vaccines ... they don't trust experts or scientists.
My mother just caught COVID last week. I was told - by people confidently claiming to speak for experts - that this wouldn't happen after she and the rest of the population were vaccinated because the spread would cease. I personally doubt the experts actually said that because they tend to be accurate in their field of expertise but good luck with that perspective around the time of the vaccine mandates.
I suspect even more than lack of trust that the issue is experts are so rare in politics that people don't recognise them when they do turn up. There are a lot of unexperts playing pretend on such topics and expert opinions are subject to misrepresentation.
