I'm not saying I'm surprised they believe something that isn't true. We all do, myself included I'm certain. But some things would be trivial to test to see if it's true or not. I used to think carrots made your eyesight better, because that's what I was taught. I've since let go of that belief in light of new understanding and evidence. That is a claim that's harder to demonstrate, so it takes time to learn the truth of the matter. If was selling you a charm that made you bulletproof, it would be trivial to demonstrate. I'd wear it and you'd shoot me and I would be unharmed. But I'd wager money that no vendor selling such a charm would ever agree to such a simple demonstration of their wares.
