I don't know what a "materialist scientific viewpoint" is, but I'm not sure how one would seek to understand the world from other than a scientific viewpoint. You'd just be guessing based on intuition. If there's something that's real, it should be possible to investigate it in a scientific manner. For example, you could imagine a study comparing the effects of a real Reiki session to a fake one performed by an actor…
I agree with you (and upvoted). However wish to point out that, if the study gave a clear result, great you have something to work with, but if it gave a negative result, that wouldn't prove Reiki per se doesn't work. Instead it would prove that Reiki training is not necessary to obtain the same outcome in this setting. Which would also be great as something to work with. But because of logical possibilities like "ac…
If you wanted, you could also approach studying it from another direction, and try to measure the transfer of energy that supposedly occurs. There would be various ways to go about that. Obviously I seriously doubt that a rigorous experiment would actually show an energy transfer from the practitioner, but if it did, and no flaws could be found in the measurement techniques, that would be pretty interesting!
