I've met both overconfident PhD holders and intermediate sci knowledge "flat-earthers" (conspiracy theory propagationists). Both are really hard to talk to, and both one couldn't convince they are wrong. I observed both being wrong. And meanwhile some of conspiracy theories became true... It's really hard to by sure of anything these days
