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.
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
