I tried to post this on /x/ but it was promptly deleted , maybe it will find a better reception here
I have a theory that people who believe in the paranormal have below average IQ as a group and have a disproportionately low percentage of gifted or above level IQ.
Any ideas on how to go about testing this theory of mine?

I do not mean to suggest that there are not many of you with IQ up to say 115 or 120.
I do think that almost none are over 125. Maybe none at all
