Okay, so let's forget Randi, though your reply sounds like rationalization to me. If these techniques worked as demonstrated, we'd almost certainly read about them in scientific journals. Scientists get a lot of notoriety and build a great reputation (which can actually help them make more money) if they publish studies that put forth evidence contrary to what other scientists think they know. If this worked, I'd expect some ambitious scientist to be testing it. If those tests showed even a little promise, they would be published in journals. And sensational results like that would certainly be picked up by the media.
I also believe seeing scientific proofs are useful in supporting beliefs. I think there are two problems with this approach in regard to the OP's belief and support as it has been expressed.
First, in order to get the study you wish, a professor or scientist would have to get funding. Just based on the reactions here in this thread, and other threads which speak of the use of Gi, where do you suppose the money for a study would come from? And how much control over the outcome would anyone providing the funding require.
Second, if the use of Gi is from a faith foundation, how do you scientifically study that? Then if you believe there are good and bad influences in the world, would you also wish to scientifically study from which influence that ability came, and how would you conduct such studies?
My personal belief is that the OP believes what she is posting (assuming that the OP is female from the avatar photo only). I am not prepared to believe what she posts until I can personally learn, or test the abilities of practitioners.
This is where my doubt comes into play. What I see is "earth shattering" but the response to it being done isn't "earth shattering" I don't hear anything about scientific studies being done, or scientist trying to figure out how the body is able to do perform the feat.
I would be more comfortable with reading scientific studies than seeing a demo. I'm not calling anyone a liar, it's just that my brain goes into caution overload with stuff like this. Something so big lands in the ocean but doesn't make a splash.
Scientific studies are indeed useful. One just needs to research the funding, methodology, and the statement at its beginning to see if any bias is detected.
And on the others side, one needs to be observant for attempts by charlatans to deny participation, or methodology as an excuse not to participate in a study or in an attempt to debunk a study.
I don't think it would be an easy thing for a scientific study by believers or detractors
