My friend who is participating in the dowsing test emailed me. Here is part of the email:
Please bear in mind that we are testing a specific and limited form of dowsing - I have never made any claims regarding dowsing for water, underground cavities, or anything other than ferrous metals - in fact, I am very skeptical about these other types of dowsing. We could also test the subterranean flowing water type of dowsing in another experiment, but it would require a different, and more complicated, test setup. I'd also like to build a dowsing machine to totally remove human subjectivity from the process, but this too is for later. Do you have a date or place in mind? We need to make this into a fun interesting event!
My response:
You are correct. First priority is that the test must be fun. I propose that all the guests at the party state which result they think will prevail, Skepticism or Dowsing. They are each given something to identify their position (preferably a silly hat). Each t…

DRUNKEN DOWSING: cherry picking

I want to talk a little bit about a logical fallacy called “Cherry Picking,” but first I should bring you up to date on the dowsing test that my friend and I are working on.
I was really pleased with what my dowsing friend Tom (not his real name) said at the last party. He suggested for the dowsing test I hide rebar in one of several PVC pipes. I went to Home Depot and purchased some 2 ½“ PVC and 4 pieces of rebar. I plan to cluster the 4 pieces of rebar together and place the cluster in one of five PVC pipes for him to pick.
I was thinking that the day of the test Tom could designate 5 spots in the backyard that he feels are clear of any interference. We could put towels down to mark those spots. I would then place the PVC pipes on those spots. He would use his dowsing ability to pick which PVC pipe contained the cluster of rebar. We would do this a number of times. Each time I would switch out which piece of PVC contained the rebar.
Tom thought each round should have 10 choices (10 pie…


Here is the next installment of the dowsing test.

(DOWSER- TOM – not his real name)
Let’s make the Dowsing experiment into a kind of performance piece/party! I'll bring plenty of dowsing rods - I know that after I prove that dowsing is true, everyone will want to learn how. Maybe even you!

A test at a party would be great but not at the one coming up. We have not yet come up with the protocol for the experiment. And as the Wicked Witch of the West has said, "These things have to be done delicately."
I would love to learn how to dowse. You may not know this but there are a number of science organizations around the world which will award you large sums of money (we are talking a million dollars) if you can demonstrate to them that you can do what you claim. But we are getting a little ahead of ourselves. Why don't we see if you can dowse first? Then we can have a dowsing rave because you are going to be rich.
From what I have read these science groups usually start out…
