Yup, except for people who have experienced hallucinations, day dreams, delusions, optical illusions, magic tricks, etc..
The way our brain can conspire to trick us into false beliefs is almost limitless. The very definition of self delusion is that the person who is deluded does not recognize that fact in them selves, they TOO believe they have validated their belief so they can't be mistaken.. To think that YOU would somehow be able to recognize if you were deluded or that you are immune to being mistaken about your interpretation of reality is what gets you into trouble.
Every wacky belief you've ever heard of is validated by someone's personal objective experience. The only way to be confident about which are actually real and which aren't is what Science
was invented for.
says that after 14 years, there is not a single verified case of Miracle-Mineral-Supplement
curing anyone of a serious illness. Not one. We live in the information age, if Miracle-Mineral-Supplement
was really curing people of AIDS, by now it should be trivially easy to find a verified case somewhere, but there is none.
