It comes down to something very simple. If someone claims to have a cure for cancer, you would be seeing everyone getting cured of cancer. If people could fly you would see people flying all the time. If people could actually move objects with their minds, you would be seeing people doing it all the time in real life yet you don't. There are only stupid youtube videos and that's about it, just like there are videos about ghosts and other stupid shit.
Your explanation is not as simple as using the scientific method to answer these questions. What exactly is unscientific about these tests? You simply do not want to address the research or inquire into the facts because it is in conflict with your belief system (BS).
