This isn't a child or anything, they're a grown adult.
I know a person who really believes in a lot of supernatural bullshit, and refuses to get back to reality.
Some notable things they've done would include spending a few hundred dollars on special 'healing' rocks, blaming everyone's behavior (including their own) on astrology signs, and actually warning me, as though they were concerned for my safety, about not getting into occult things (I made a dumb joke about Satan worship) because of this story they've heard about a guy buying an ouija board and having to sell it on eBay because some spoopy shit was happening.
Whenever I tell them that science has produced no evidence of any of these things, or that the easiest explanation to all of those things would be fake stories, ancient superstition, and the placebo effect, they'll just respond with "Well just because nobody's proven it yet doesn't mean it doesn't exist".
Then I'll ask them if we should believe in unicorns or purple elephants or something stupid, and just assume they haven't been found yet. To which they'll respond with a smug "Maybe, who knows? Nobody can know everything for sure."
How do I convince them that they believe in a bunch of delusional crap? I'm really worried they might fall down the wrong rabbit hole one day and end up getting hurt.
Never claimed to 'like science' in the way you're referring to. I just believe it's a better means of understanding the world than pure superstition. Guess that makes me insane.
Right. But is it rational to believe in something before any reliable evidence for it has surfaced?
People have believed in all sorts of supernatural crap for thousands of years, and not once has anything more than anecdotes been produced. So is it more logical to assume we just haven't found any yet, or that some people will say things that aren't true because they're liars/insane/misinformed?
This is a close family member I am talking about. If some new-age jackass is trying to take advantage of them, I would like to be able to talk them out of it. I guess that's wrong of me.
