Thanks for the prompt info. I'm looking forward to hearing more.
I applaud DowserDon for doing this kind of self-test that virtually no other MDC applicant ever does.
Despite the outcome for DowserDon, it sounds like it was a pleasant way for everyone to spend a spring day in England. I wish I could have been there.
Thanks again,

Ah, thanks for the clarification, I clearly didn't keep up with the thread.It was a self test. AIUI Chris French was there principally to assess the acceptability of the test protocol for a formal JREF test.
Within minutes of failing the test he said to me that he should have tried different materials to cover the trenches, because perhaps damp plywood was masking the signal. I pointed out that in that case he wouldn't have got a response in the unblinded test either, which he seemed to accept. Later he said that everyone who designs experiments has to accept that sometimes they fail, again implying that the design of the test must be at fault because it hadn't given the "right" result. The possibility that the test was fine and had reliably confirmed what decades of previous testing had already established was not one he seemed prepared to consider. His final comments as we were leaving were that he would let the trenches "age" for say six months and then see if he could detect them - again ignoring the fact that he was able to detect the brand new trench in the unblinded test without difficulty, and also that as he now knows where the trenches are any later testing will be unblinded and therefore worthless.Any word yet from DowserDon on why he thinks he failed the test?
I (and I think most everyone here) was afraid that would be his response.Within minutes of failing the test he said to me that he should have tried different materials to cover the trenches, because perhaps damp plywood was masking the signal.

Before we went out to start the testing he described the personal experiences which had led him to believe that dowsing really does work. Most of them (some of which he described earlier in this thread) involved him getting a dowsing reaction to something he already knew was there. The one notable exception was when he detected two responses whilst walking a cliff path; later he noticed from the beach below the cliff that waterfalls fell from those positions.DowserDon's reaction (as described by Pixel42) is not surprising. I did not expect a single failed test to shake his beliefs that are based on personal experience. If my personal experiences had been as compelling as he says his were, I doubt a single failure on my part would alter my beliefs, either.

To me this is a real mystery. I can understand how perfectly intelligent and rational people can inadvertantly fool themselves into believing something that isn't true. I can understand why they can continue to hold that belief as long as they remain ignorant of the evidence against it and the alternative explanations of the experiences that led them to it. What I can't understand is why some persist in the belief even after they've been shown compelling objective evidence that the alternative explanation is in fact the correct one.
So I'm confirming what many of you in the JREF Forum predicted - I'm blaming myself and my protocol. I am not admitting to myself that dowsing does not exist (I have been surprised too many times to consider that it is all due to the ideomotor effect). I am encouraged in this by a telephone conversation I had when I got home. It went something like this "...but you cannot have failed! You taught me and I've taught others. You must persist." As I'm easily flattered I shall indeed persist.
At a more serious level - I don't follow the arguments that one negative result should cancel out the many positive ones. Nor do I retract my statement that there have been no earlier field tests of dowsing.
Thanks for devoting your time to following the assessment of my proposed protocol yesterday. I am naturally disappointed with the result but acknowledge that it was a fair test of my proposed protocol. It was not a JREF recognised trial.
As with any scientific experiment that produced results that were not expected, there will be an analysis and then, hopefully, further development. I'm sure that is what they have been doing at the Large Hadron Collider since they turned it on - at far greater expense.

I shall update my web site within the next month with a description of yesterday's events and any further tests I plan. As Pixel 42 has quoted "The correct scientific response to anything that is not understood is always to look harder for the explanation, not give up .....". David Attenborough.
The Oxford English Dictionary says that scientific method is: "a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses." The chief characteristic which distinguishes a scientific method of inquiry from other methods of acquiring knowledge is that scientists seek to let reality speak for itself, and contradict their theories about it when those theories are incorrect. (Copied from Wikipedia).
I observed systematically. I experimented. I have a hypothesis for testing, modification and development. I was hoping that prize money would enable me to commission others in UK and a USA universities to identify and measure, what I can only qualitatively describe as dowsing.
Thanks to all the well wishers who have been following my progress.
Now to the important things in life - the lawn needs mowing.
Bye
