So, purely hypothetical proposal. Both myself and the JREF witness the preparation by independent manufacturers of the necessary homoeopathic remedies and "sham" preparations, and the appropriate labelling, and their delivery to an independent and mutually trusted lawyer.
The lawyer agrees to send or deliver to me, one at a time and on request, either the remedy I ask for, or a sham. I take my time and decide whether I got the requested remedy or not (any way I please), and notify another trusted third party, who does nothing but keep a record of my decisions. I then notify the lawyer that I'm ready for the next one, and he sends it to me. And so on.
We do this, say, 15 times (which I think would allow for sufficient statistical power). After I have delivered my 15 decisions, the lawyer who was sending out the material compares notes with the person recording my decisions, and the number of correct calls counted. If this makes it to a less than 1 in 1,000 chance that I was guessing, the preliminary phase has been passed.
Naturally, I pay all professional fees accrued by this process.
I'm asking because sometimes homoeopaths complain that it's impossible to satisfy the demands of the challenge, and it would be nice to have a simple and practical protocol that (probably, I'm not asking for guarantees here) meets the requirements.
This one lets them pick the remedy they think they can identify according to what volunteers they can scare up with what symptoms, or "prove" it themselves or on other volunteers or anything, and it lets them take their time about deciding whether the effect is there, without anyone being locked up in a room or having to take a long holiday or provide a number of people with the same disease simultaneously.
I think it's fair, I think it's secure, and I think it would work. And frankly, if I believed in homoeopathy I'd be rushing to get my application in quick before somebody beat me to it. The fact that they're all so coy and can never agree on what they think they can do says to me as clearly as anything that they know they can't do anything.
