Does dowsing work?
Of more interest than why the rods move, however, is the issue of whether dowsing works. Obviously, many people believe it does. Dowsing and other forms of divination have been around for thousands of years. There are large societies of dowsers in America and Europe and dowsers practice their art every day in all parts of the world. There have even been scientists in recent years who have offered proof that dowsing works. There must be something to it, then, or so it seems.
The testimonials of dowsers and those who observe them provide the main evidence for dowsing. The evidence is simple: dowsers find what they are dowsing for and they do this many times. What more proof of dowsing is needed? The fact that this pattern of dowsing and finding something occurs repeatedly leads many dowsers and their advocates to make the causal connection between dowsing and finding water, oil, minerals, golf balls, etc. This type of fallacious reasoning is known as post hoc reasoning and is a very common basis for belief in paranormal powers. It is essentially unscientific and invalid. Scientific thinking includes being constantly vigilant against self-deception and being careful not to rely upon insight or intuition in place of rigorous and precise empirical testing of theoretical and causal claims. Every controlled study of dowsers, including the "Scheunen" study [see below], has shown that dowsers do no better than chance in finding what they are looking for.
Most dowsers do not consider it important to doubt their dowsing powers or to wonder if they are self-deceived. They never consider doing a controlled scientific test of their powers. They think that the fact that they have been successful over the years at dowsing is proof enough. When dowsers are scientifically tested and fail, they generally react with genuine surprise. Typical is what happened when James Randi tested some dowsers using a protocol they all agreed upon. If they could locate water in underground pipes at an 80% success rate they would get $10,000 (now the prize is over $1,000,000). All the dowsers failed the test, though each claimed to be highly successful in finding water using a variety of non-scientific instruments, including a pendulum. Says Randi, "the sad fact is that dowsers are no better at finding water than anyone else. Drill a well almost anywhere in an area where water is geologically possible, and you will find it."
Some of the strongest evidence for dowsing comes from Germany and the so-called "Scheunen" or "Barn" experiment. In 1987 and 1988, more than 500 dowsers participated in more than 10,000 double-blind tests set up by physicists in a barn near Munich. (Scheune is the German word for barn.) The researchers claim they empirically proved "a real dowsing phenomenon." Jim Enright of the Scripps Institute of Oceanography evaluated the data and concluded that the so-called "real dowsing phenomenon" can reasonably be attributed to chance. His argument is rather lengthy, but here is a taste of it:
The long and the short of it is that dowsing performance in the Scheunen experiments was not reproducible. It was not reproducible inter-individually: from a pool of some 500 self-proclaimed dowsers, the researchers selected for their critical experiments 43 candidates whom they considered most promising on the basis of preliminary testing; but the investigators themselves ended up being impressed with only a few of the performances of only a small handful from that select group. And, even more troublesome for the hypothesis, dowsing performance was not reproducible intra-individually: those few dowsers, who on one occasion or another seemed to do relatively well, were in their other comparable test series usually no more successful than the rest of the "unskilled" dowsers (Enright ?Water Dowsing: the Scheunen Experiments,? Naturwissenschaften, vol. 82 1995).
The Barn study itself is curious. It seems clearly to have been repudiated by another German study done in 1992 by a group of German scientists and skeptics. The Gesellschaft zur wissenschaftlichen Untersuchung von Parawissenschaften (GWUP) [Society for the Scientific Investigation of the Parasciences] set up a three-day controlled test of some thirty dowsers, mostly from Germany. The test was done at Kassel, north of Frankfurt, and televised by a local television station. The test involved plastic pipe buried 50 centimeters in a level field through which a large flow of water could be controlled and directed. On the surface, the position of the pipe was marked with a colored stripe, so all the dowsers had to do was tell whether there was water running through the pipe. All the dowsers signed a statement that they agreed the test was a fair test of their abilities and that they expected a 100% success rate. The results were what one would expect by chance (Randi, 1995). Defenders of dowsing do not care for these results, and continue to claim that the Barn study provides scientific proof of dowsing.
After the usual ad-hominems, whining and hand-wringing is done; NOT ONE PERSON will put up an equal amount of money up to $20,000 to take the Swami Dowsing Challenge. Hasn't changed in 5 years. Won't change in the future.

The proof is in the pudding.
