From development to widespread acceptance QM didn’t take very long, because of course it’s possible to test to a high degree of accuracy. Flat Earth was debunked many centuries (millennia really) ago, but still persists. I’m not sure how much more critique needs to be done, or what questions can be raised. Most people are aware of it, and rightly dismiss it. The only people who think it should be treated seriously are people who, believe in it.
So why entertain it? Because of some vague ideological opposition to curation? It seems to me, from experience at least, thst it usually has to do with a desire to use “universal acceptance” as an excuse to smuggle someone’s own pet crank idea into the mix. Creationists don’t seriously care about scientific inquiry or bias, they just started using those lines when legal bans on teaching evolution failed. Fascists and racists turned from trying to dominate society, to undermining it.
Once an idea has been thoroughly and comprehensively discredited it’s a waste of time at best, propaganda at worst. Yes, it can be challenging to deal with ideas on the borderline, and we should always try harder, but the solution isn’t intellectual nihilism. Ceasing to use any critical thinking because it might invite bias is a bad idea, and I think only really put forth by people who’s marginal ideas have no other hope of being heard.
After all, terrible ideas are documented, but there’s no moral, practical or intellectual reasons to document them everywhere.
