Is all of psychology falsifiable?
Just how many cultures had things that may be called deities talk to them? As far as I can tell, almost all Earth cultures have had that. We're talking about the Oracle of Delphi in here - and according to lore, was divinations (as in Divine messages). So, again, I ask - what's really going on? And this wasn't the only one.
And what's more curious and interesting is how durable groups that do occult stuff are. John Dee was Queen Elizabeth's court magister, and created the whole Enochian system in the 1570s. Of course, this can be glossed over due to them not really understanding science. But we have a magical heritage even way before Dee to now.
And infamous occultist, Aleister Crowley, even said that "Magick is the Science and Art of causing Change to occur in conformity with Will." Those are certainly things to inquire - can we see effects? How do they work? How do they not work? Can others sense them? How do we go about sensing it?
Long story short, I see that there's something there. And a whole lot of other people do as well. Enough anecdotes starts to equal a study. And what's the worst that will happen? That I fail? (And even if I fail, still provides more data that wasn't done before; hence a success.)
Can you pull of this same trick with humans, across all their behaviors?
