To answer angel Can I prove that Reiki doesn't work? - yes it has already been proven by peer reviewed clinical trials. If you and I were of a mind to we could set up our own clinical trial and prove it to ourselves in person.
I have a problem with any belief system that has been disproved. eg. I do not have any respect whatsoever for the belief that the earth is flat. I don't need to be open minded, I don't need to take on board anyone's opinion. It has been proved that the Earth is not flat and what is more, I can prove it myself.
You don't get an opinion on maths. 2+2=4. you cannot say, well in my belief system 2+2=5 and you have to respect that different people have different opinions.
You don't get an opinion on physics. Electrons are allowed to have the same energy/frequency, this is a fact. You can not say oh but I just have a different opinion, so you have to respect that too.
And you don't get an opinion on clinical trials. The data are there and they are true. The only option you have is to collect more data and see if the consensus of the data changes. It appears there have been getting on for 100 trials on Reiki so your new data would have to be wildly different from anything previously collected to make an impact. Obviously getting a wildly different answer from everyone else is unlikely in the extreme. If you look at something like homeopathy there have been thousands of trials so the job of overturning the consensus is so enormous that it is reasonable to consider it impossible.
But go for it.
Design your own trial. You need to:
Get at least 100 people. Split them RANDOMLY (this is important) into two groups. You must NEVER let them know which group they are in (this is the most important thing of all). Subject one group to the very best Reiki you can. Send the other group to me and I will subject them to the very best Reiki that I can. We then compare some measure from satisfaction, to perceived energy levels to pain relief...whatever you wish to find out really.
It is very likely (given all the evidence already collected on this topic) that we will find no difference between the results of our two groups.
The question is, will you then accept that it doesn't work?
Because I will tell you something. If we find that there IS a big difference between the outcomes in the two groups AND everything about the trial has been done correctly then I WILL change my mind.
Because I am intelligent and I don't let my beliefs get in the way of what the evidence actually says.
