Sorry, I accidentally cut? undid? a piece of text. I meant that the same way James Randi smartly sabotages the claimers, for example remote viewres by breaking the ether around them, astrlogers with stuff that only expert ancient astrologers knew would make it fail, etc. (My mom was an astrloger, and I grew up on a home seeing the people breaking in tears because she would tell them exactly the day of the year when something would happen, and it did)
Anyway, proving something which has not been fully understood is really hard, even more when others KNOW how it work and their whole work is to make sure others fail.
