The definition of the term, "double blind," means that
both sides are "blind" to what is going on.
In the case of the LRL tests,
both the person operating the LRL, and the person administering the test, are "blind" to where the target is hidden. The way the administrator is kept in the "blind," is to have another person hide the target. Then the person who hid the target
leaves the area before the administrator and the LRL operator enter the area.
The point being, that nobody in the visible test area knows where the target is, so there cannot be any subconscious cues given to indicate where the target is, or if the LRL operator is getting closer or farther from the target.
So the test is completely fair.
A manufacturer, or you, can use your best LRL operator. 10 tests like the above are done. You win if you find the target 7 times out of the 10 tests.

Lets see now..How about 10 LRL users, 10 dowsers and 10 people who have never done any of these thing..Also a test set up as per the definition of a Double blind Test..Art
Ask Carl if you can use 10 different operators, and different LRLs. He indicates in the rules that he is flexible about stuff like that. He would probably do that.
I don't know what the 10 dowsers would be there for, if the test is for LRLs, though. And I'm not sure what the other 10 would be for. Unless you want to prove that the LRLs work better than the dowsers, and the dowsers work better than the people who've never done either before.
I can't even guess whether Carl would be interested in that kind of test, as he has challenged LRLs, not dowsers. But maybe you can do a Randi test and a Carl test at the same time, or something.
Or course, if someone had a LRL that didn't work very well, if he brought his own dowsers, he could tell them to do poorly, just to make the LRL do better than them. But even if a test like that were done, I'm fairly certain it would still require a 70% hit ratio for the LRLs, so the dowsers being tested wouldn't help the LRL tests at all.
What would be your purpose of having the dowsers and beginner dowsers tested? I don't understand that part.
How would you have the test set up to meet your definition of "double-blind" test. How would it be different than what Carl has in his rules? I don't understand how it could comply with the double-blind standard any more than it already does.
What do you have in mind for your version of the test, step by step?
