Agreed. One mental example I use is that imagine someone brought you proof of a ghost. Maybe it's a testimony from someone who is rational and wouldn't ever lie, maybe it's some unexplainable photograph or phenomenon.

If you didn't believe in ghosts before and then suddenly switched to believing in them, then your entire worldview changes - the soul exists and can exert itself into reality, the afterlife is real, maybe emotions exert some real phenomenon too, and so maybe wishing makes things happen too!

That, in and of itself, would be irrational, to change your entire worldview based on single pieces of evidence, even if they do appear to be true
