Having though a little longer on this topic -- and at the same time watching the news and trying to keep up with what's being said here and elsewhere in the world of the web -- I have something that I'd like to add...
Religion does, in fact, encourage unskeptical belief, at least in the things that the religion focuses on. But unskeptical belief can easily become a habit -- after all, it's so much less work than trying to uncover the truth, isn't it?
And this leads me to the propensity to belief in so many absurd "conspiracy theories" -- especially, I think, in the US. After all, how many Americans believe firmly that the 2020 election was "stolen" from Republicans? (For the record, it wasn't!) But they were told it was -- so of course they believe it, when if they really thought about it at all, they'd see such a notion is purest nonsense. And why do so many believe in the disproven "Qanon" theory? Obvious bunk, but once again, they were told by those they consider reliable sources, and therefore had zero need to look any further.
Wikipedia has a nice list of such conspiracy theories, which you can look at if you think it's a rare phenomenon. It's not!
