For the initial investigation, it suffices to find any difference at all between reiki hands and non-reiki hands. If we use every measurement device humanity has at its disposal, and find no difference, it is safe to conclude that the visible effects of reiki have no discernable cause of action beyond the placebo effect--which can be reliably generated by putting sufficient flimflammery in your bunkum. If there is a difference, it should be measurable. And repeatably measurable using standardized testing devices with SI-derived units. If there is a genuine effect that can only be measured by its effect on biology, then obviously one should be able to build a measurement tool using biological cells. If reiki is real, it can be explained, one question at a time.
