This time I used the Reply button instead of the Quote button, and I *still* got the Rasmus post

Hmmm .... Maybe that's paranormal right there, and the prize would belong to ... the developers of VBulletin? JREF's web host? Rasmus?
Claim A has some precedent, you say. I'd like to see that.
I can see your point about derailing the discussion. Maybe there should be a thread for each potential Claim But isn't it part of the process in this case to analyze the pros and cons of each proposal in relation to the others?
At this stage I am feeling most inclined toward choosing Claim B, and have a few ideas for making the proposed protocol more workable. One thing is I can agree to wear a blindfold, to exclude the possibility that I was somehow reading body language and/or facial expression well enough to see that "this person looks so gloomy, I bet s/he suspects s/he is doomed, and is in a lot of pain" and thus probably has cancer. Doing so would disable me from writing notes on the cards, but there may be a way around that, such as, after the person walks away, I can sit down in a little curtained-off booth and make notes about them before the next person comes up.
Alternatively - and this might solve a major logistical problem with Claim B - the Referee and someone from JREF could accompany me to a big hospital if the hospital agrees to allow me to be led, blindfolded, from room to room for a quick visit with 60 or more sick people, at least 10% of whom are undergoing cancer treatment. We could pause between visits for me to write my notes. It might even be harder for JREF to cheat doing it that way, as opposed to having the cancer patients gather in a central test location.
It might also be convenient to visit a big hospital for a chance to test Claim C. I think it's a good bet that a lot of people die in hospitals on a daily basis. Some if not all hospitals have autopsy facilities, so there might be a ripe opportunity to test Claim C. I can't really imagine any hospital personnel above the level of janitor agreeing to allow such a test in their facility, but it might be worth looking into.
