What I gather from these types of conspiracy theories is a kind of logic like “what if reality is exactly as simple as it seems prima facie,” and then from that they make all kinds of pseudo-empirical conjectures based on a anecdotal reasoning.

There’s nothing wrong with going out into the weeds with your thinking and doubting everything, for a bit (as a treat). But they seem to fail to realise when their hypotheses are actually far clunkier than the established science, so they just stay out there on the fringes of reason getting wilder and more unhinged.

PS and probably there’s some racism or antisemitism driving the whole thing, even if they don’t see it.
