To the editor: I am unhappy to see the Record pushing pseudoscience, in Valerie Hill's June 10 article about dowsing. Not a single skeptical word could be found in her gullible treatment. Scientific tests have shown repeatedly that dowsers do not perform better than pure chance. The ideomotor effect causes a dowser's stick to dip -- it has nothing to do with magnetic fields. Macarthur prize winner James Randi offers $1 million to anyone who can exhibit paranormal abilities in a repeatable fashion. Dowsers have repeatedly attempted to win this prize, but all have failed.
