lesjcbs, I have read your explanation . I see that you have not glossed over the fact that there were attempts to make the tests fair and impartial. You acknowledge that the dowsers themselves made the claims on how it works. And under what circumstances it can be tested, their abilities, etc.... Rather than an "unfair" test on the part of the challengers, you agree that it's simply going by the claims and standards of the dowsers themselves . Ok.
But then you distance yourself from the fairness of this, by saying that the dowsers were then "suckered" into the test. By the challengers preying on this confidence. As if to imply that the challengers knew that the "circumstances" of the test would be different (subtly, yet enough to cause the failure). And that the testers were using "magic tricks", etc...
Then, pray-tell, how can it ever be tested ? No matter HOW much the dowsers are quizzed ahead of time about the requirements of settings, etc.. And no matter HOW MUCH the two sides mutually agree ahead of time , .... then upon failure: What's to stop the dowsers from saying the very things you are saying now ? It sounds like a "convenient" fall-back, eh ?
So what test (beyond "personal testimony" ) can ever be done ? Apparently none.
..... dowsing used as a means and method to locate targets, even precious metals, is an established undeniable fact...
Really ? Beyond "personal testimony" ? If there is anything besides personal testimony that can show this, I would very much like to see it. I would accept "personal testimony" if it did not have any accompanying "more plausible explanations". But the minute anything is done to rule out such more-plausible-explanations, is the minute the dowser will cry "foul", right ? Because that's the "minute" it becomes a "test". Andi s therefore the minute the fall-back lines get rolled out.
..... undeniable fact in world history. ...
The thing I see as "undeniable fact of world history", is that many people *claim* (personal testimony) to be able to do it. Yet can never show or prove it beyond personal testimony claims. It's their sincere beliefs. Which do not take into account more-plausible-explanations. So for example, your coins and aluminum in the park: Some persons would consider the "more plausible explanation" to be that : The random odds of going to any park anywhere, picking a spot at random, and turning on a detector .... you will find metal.
Yes yes I know you deny that. So if two sides sit down to establish WHETHER OR NOT that WAS the "more plausible explanation" or not, they can never do it. Any time the results of a test showed that, in fact, my explanation was "more plausible", you would cite the fall-back lines: Skewed testing conditions, magic tricks, etc.... Right ?
.... at the end of that video you put up, after all failed to find the water line, all still said dowsing works. The reason is they and they alone know what their record is and it would be more than foolish to deny or doubt it ....
That is one explanation for their failure to concede. Another explanation could be that the human mind has a history of believing in, and falling for, snake-oils.
Consider cultures with witch doctors who perform incantations, dances, pixie dusts, etc... to cure ailments. Would you rather go to that type doctor for hernia surgery ? Or a doctor here in the USA who practices conventional medicine ? Yet I betcha that witch doctor "still believes". And has personal testimony of supposed successes on his part. Naturally there are more plausible explanations for any supposed cures on his part. Hence the fact of those dowsers "still believe" can be nothing more than strongly held superstitions. Simple human nature.
