Divining Rods

Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, claimed radiations (radiesthesia),As translated from one preface of the Kassel experiments, "roughly 10,000 active dowsers in Germany ''alone'' can generate a conservatively-estimated annual revenue of more than 100 million DM (US$50 million)"
''GWUP-Psi-Tests 2004: Keine Million Dollar für PSI-Fähigkeiten''

. gravesites, malign "earth vibrations" and many other objects and materials without the use of a scientific apparatus. It is also known as divining (especially in water divining), doodlebugging (particularly in the United States, in searching for petroleum or treasure) or (when searching for water) water finding, or water witching (in the United States).

A Y-shaped twig or rod, or two L-shaped ones—individually called a dowsing rod, divining rod (Latin: ''virgula divina'' or ''baculus divinatorius''), vining rod, or witching rod—are sometimes used during dowsing, although some dowsers use other equipment or no equipment at all. The motion of such dowsing devices is generally attributed to the ideomotor phenomenon,Zusne, Leonard; Jones, Warren H. (1989). ''Anomalistic Psychology: A Study of Magical Thinking''. Lawrence Erlbaum Associates, Inc. pp. 105–110. Novella, Steve; Deangelis, Perry. (2002). ''Dowsing''. In Michael Shermer. ''The Skeptic Encyclopedia of Pseudoscience''. ABC-CLIO. pp. 93–94. "Despite widespread belief, careful investigation has demonstrated that the technique of dowsing simply does not work. No researcher has been able to prove under controlled conditions that dowsing has any genuine divining power... A more likely explanation for the movement of a dowser's focus is the ideomotor effect, which entails involuntary and unconscious motor behavior."Lawson, T. J; Crane, L. L. (2014). ''Dowsing Rods Designed to Sharpen Critical Thinking and Understanding of Ideomotor Action''. ''Teaching of Psychology'' 41 (1): 52–56. a psychological response where a subject makes motions unconsciously. Put simply, dowsing rods respond to the user's accidental or involuntary movements.

The scientific evidence is that dowsing is no more effective than random chance. via Regal, Brian. (2009). ''Pseudoscience: A Critical Encyclopedia''. Greenwood Press. pp. 55–57. It is therefore regarded as a pseudoscience.

History

Early divination and religion

Dowsing originated in ancient times, when it was treated as a form of divination. The Catholic Church, however, banned the practice completely.Inglis (1986) pp. 246–247.

Reformer Martin Luther perpetuated the Catholic ban, in 1518 listing divining for metals as an act that broke the first commandment (i.e., as occultism).''Decem praecepta Wittenbergensi populo praedicta'', Martin Luther

Old texts about searching for water do not mention using the divining twig, and the first account of this practice was in 1568.

Sir William F. Barrett wrote in his 1911 book ''Psychical Research'' that:

In 1662, divining with rods was declared to be "superstitious, or rather satanic" by a Jesuit, Gaspar Schott, though he later noted that he was not sure that the devil was always responsible for the movement of the rod.Michel Eugène Chevreul, ''De La Baguette Divinatoire du pendule dit explorateur at des table tournants au point de vue de l'histoire, de la critique, and de la méthode expérimentale'', Paris, 1854. "''Le père Gaspard Schott (jés.) considère l'usage de la baguette comme superstitieux ou plutôt diabolique, mais des renseignements qui lui furent donnés plus tard par des hommes qu'il considérait comme religieux et probe, lui firent dire dans une notation à ce passage, qu'il ne voudrait pas assurer que le demon fait toujours ''tourner'' la baguette.''" (''Physica Curiosa'', 1662, lib. XII, cap. IV, pag. 1527). Se

on Google Books In southern France in the seventeenth century it was used in tracking criminals and heretics. Its abuse led to a decree of the inquisition in 1701, forbidding its employment for purposes of justice.

An epigram by Samuel Sheppard, from ''Epigrams theological, philosophical, and romantick'' (1651) runs thus:

Modern dowsing

Despite religious disapproval, dowsing was practiced in Germany during the sixteenth century much as it is practiced today, when it was used in attempts to find metals. The 1550 edition of Sebastian Münster's '' Cosmographia'' contains a woodcut of a dowser with forked rod in hand walking over a cutaway image of a mining operation. The rod is labeled in Latin and German; "''Virgula Divina – Glück-Rüt''" (Rod Divine, Luck-Rod), but there is no text accompanying the woodcut. By 1556, Georgius Agricola's treatment of mining and smelting of ore, '' De Re Metallica'', included a detailed description of dowsing for metal ore.William Barrett and Theodore Besterman. ''The Divining Rod: An Experimental and Psychological Investigation.'' (1926) Kessinger Publishing, 2004: p. 7

In the sixteenth century, German deep mining technology was in enormous demand all over Europe. German miners were licensed to live and work in England; particularly in the Stannaries (tin mines) of Devon and Cornwall and in Cumbria. In other parts of England, the technique was used in the royal mines for calamine. By 1638 German miners were recorded using the technique in silver mines in Wales.

The Middle Low German name for a forked stick (Y-rod) was ''Schlag-Ruthe'' ("striking rod"). This was translated in the sixteenth century Cornish dialect to ''duschen'' (''duschan'' according to William Barrett) (Middle English, to "strike" or fall). By the seventeenth century the English term "dowsing" was coming into common use.

In the lead-mining area of the Mendip Hills in Somerset, England in the seventeenth century the natural philosopher Robert Boyle, inspired by the writings of Agricola, watched a practitioner try to find "latent veins of metals". Boyle saw the hazel divining rod ("''virgula divinatoria''") stoop in the hands of the diviner, who protested that he was not applying any force to the twig; Boyle accepted the man's genuine belief but himself remained unconvinced. Towards the end of the century, in 1691 the philosopher John Locke, who was born in the English West Country, used the term ''deusing-rod'' for the Old Latin name ''virgula divina''. So, ''dowse'' is synonymous with ''strike'', hence the phrases: to ''dowse''/''strike'' a light, to ''dowse''/''strike'' a sail.

Dowsing was conducted in South Dakota in the late nineteenth and early twentieth centuries to help homesteaders, farmers, and ranchers locate water wells on their property.Grace Fairchild and Walker D. Wyman, Frontier Woman: The Life of a Woman Homesteader on the Dakota Frontier (River Falls: University of Wisconsin-River Falls Press, 1972), 50; Robert Amerson, From the Hidewood: Memories of a Dakota Neighborhood (St. Paul: Minnesota Historical Society Press, 1996), 290–298.

The military have occasionally resorted to dowsing techniques. In the First World War Gallipoli campaign, sapper Kelly became well known for finding water for the British troops. In the late 1960s during the Vietnam War, some United States Marines used dowsing when locating weapons and tunnels.FIX ME (could not access entire article) As late as in 1986, when 31 soldiers were taken by an avalanche during an operation in the NATO drill Anchor Express in Vassdalen, Norway, the Norwegian army attempted to locate soldiers buried in the avalanche using dowsing as a search method.

Dowsing is still used by some farmers and by water engineers in Britain, however many of the United Kingdom's water utilities have since tried to distance themselves from the practice.California Farmers Hire Dowsers to Find Water

Postulated mechanisms

Early attempts at an explanation of dowsing were based on the notion that the divining rod was physically affected by emanations from substances of interest. The following explanation is from William Pryce's 1778 ''Mineralogia Cornubiensis'':

A study towards the end of the nineteenth century concluded that the phenomenon was attributed to cryptesthesia, where the practitioner makes unconscious observations of the terrain and involuntarily influences the movement of the rod. Early investigations by members of the Society for Psychical Research endorsed this view.Inglis (1986), pp.254-5.

Committed parapsychologist G. N. M. Tyrrell also believed that the action of the rod was caused by involuntary muscular movements and debunked the theory of external influences.

However dowsing over maps, prior to visiting the site, was also believed to work, and so some kind of clairvoyance was proposed. This was believed to act on the nervous system, rather than on the muscles directly. These various mechanisms remain in contention among dowsers.

Fraudulent security devices

In the late twentieth and early twenty-first centuries a number of dowsing-like devices were marketed for modern police and military use, primarily as explosive detectors, such as the ADE 651, Sniffex, and the GT200.Double-Blind Field Evaluation of the MOLE Programmable Detection System
Sandia National Laboratories In consequence of these frauds, in 1999 the United States National Institute of Justice issued advice against buying equipment based on dowsing.

Equipment

The device used by a dowser is typically referred to as a dowsing or divining rod, even though it may not be rod-shaped.

Dowsing twig

Traditionally, the most common method used is the dowsing twig, a forked (Y-shaped) branch from a tree or bush. Some dowsers prefer branches from particular trees, and some prefer the branches to be freshly cut. Hazel twigs in Europe and witch-hazel in the United States are traditionally commonly chosen, as are branches from willow or peach trees. The two ends on the forked side are held one in each hand with the third (the stem of the Y) pointing straight ahead. The dowser then walks slowly over the places where he suspects the target (for example, minerals or water) may be, and the dowsing rod is expected to dip, incline or twitch when a discovery is made.Inglis (1986) This method is sometimes known as "willow witching." Some dowsers would hang a golden ring on the edge of the dowsing rod, or split the tip to slide in a silver coin.

Pair of rods

Many dowsers today use a pair of L-shaped metal rods. One rod is held in each hand, with the short arm of the L held upright, and the long arm pointing forward. The upright arm is often free to rotate inside a tube. When something is "found," the rods move in synchrony. Depending on the dowser, they may cross over or swing apart. If the object is long and straight, such as a water pipe, the rods may point in opposite directions, showing its orientation. The rods may be fashioned from wire coat hangers or wire flags used for locating utilities. Glass or plastic rods have also been accepted. Straight rods are also sometimes used for the same purposes, and were not uncommon in early-nineteenth-century New England.

Pendulum

A pendulum weight on a short cord or thread is the tool of choice for many modern dowsers.Inglis (1986), pp. 245–246 The dowser holds the cord in one hand and allows the pendulum to swing freely. The dowser then observes how the pendulum is swinging and interprets the motion to offer insights.William Bown;

* Physicists John Taylor and Eduardo Balanovski reported in 1978 a series of experiments they conducted that searched for unusual electromagnetic fields emitted by dowsing subjects, they did not detect any.
* A 1979 review by Evon Z. Vogt and Ray Hyman examined many controlled studies of dowsing for water, and found that none of them showed better than chance results.
* Three British academics Richard N. Bailey, Eric Cambridge and H. Denis Briggs carried out dowsing experiments at the grounds of various churches. They reported successful results in their book ''Dowsing and Church Archaeology'' (1988).Leusen, Martijn Van. (1998). ''Dowsing and Archaeology''. Archaeological Prospection 5: 123–138. Their experiments were critically examined by archaeologist Martijn Van Leusen who suggested they were badly designed and the authors had redefined the test parameters on what was classified as a "hit" or "miss" to obtain positive results.
* A 2006 study of grave dowsing in Iowa reviewed 14 published studies and determined that none of them correctly predicted the location of human burials, and simple scientific experiments demonstrated that the fundamental principles commonly used to explain grave dowsing were incorrect.
* A randomized double-blind trial in 2012 was carried out to determine whether homeopaths were able to distinguish between Bryonia and placebo by use of a dowsing method. The results were negative.McCarney R, Fisher P, Spink F, Flint G, van Haselen R. (2002)

. was undertaken in Kassel, Germany, under the direction of the ''Gesellschaft zur Wissenschaftlichen Untersuchung von Parawissenschaften'' (Society for the Scientific Investigation of the Parasciences). James Randi offered a US$10,000 prize to any successful dowser. The three-day test of some thirty dowsers involved plastic pipes through which water flow could be controlled and directed. The pipes were buried under a level field, the position of each marked on the surface with a colored strip. The dowsers had to tell whether water was running through each pipe. All the dowsers signed a statement agreeing this was a fair test of their abilities and that they expected a 100% success rate. However, the results were no better than chance, and no one was awarded the prize.

Betz 1990 study

In a 1987–88 study in Munich by Hans-Dieter Betz and other scientists, 500 dowsers were initially tested for their skill, and the experimenters selected the best 43 among them for further tests. Water was pumped through a pipe on the ground floor of a two-story barn. Before each test, the pipe was moved in a direction perpendicular to the water flow. On the upper floor, each dowser was asked to determine the position of the pipe. Over two years, the dowsers performed 843 such tests and, of the 43 pre-selected and extensively tested candidates, at least 37 showed no dowsing ability. The results from the remaining 6 were said to be better than chance, resulting in the experimenters' conclusion that some dowsers "in particular tasks, showed an extraordinarily high rate of success, which can scarcely if at all be explained as due to chance … a real core of dowser-phenomena can be regarded as empirically proven."Wagner, H., H.-D. Betz, and H. L. König, 1990. Schlußbericht 01 KB8602, Bundesministerium für Forschung und Technologie
As quoted by Jim T. Enright
in the ''Skeptical Inquirer''.

Five years after the Munich study was published, Jim T. Enright, a professor of physiology who emphasized correct data analysis procedure, contended that the study's results are merely consistent with statistical fluctuations and not significant. He believed the experiments provided "the most convincing disproof imaginable that dowsers can do what they claim", stating that the data analysis was "special, unconventional and customized". Replacing it with "more ordinary analyses", he noted that the ''best'' dowser was on average out of closer to a mid-line guess, an advantage of 0.04%, and that the five other "good" dowsers were on average farther than a mid-line guess. Enright emphasized that the experimenters should have decided beforehand how to statistically analyze the results; if they only afterward chose the statistical analysis that showed the greatest success, then their conclusions would not be valid until replicated by another test analyzed by the same method. He further pointed out that the six "good" dowsers did not perform any better than chance in separate tests. Another study published in ''Pathophysiology'' hypothesized that such experiments as this one that were carried out in the twentieth century could have been interfered with by man-made radio frequency radiation, as test subjects' bodies absorbed the radio waves and unconscious hand movement reactions took place following the standing waves or intensity variations.

Scientific reception

Ideomotor phenomenon

Science writers such as William Benjamin Carpenter (1877), Millais Culpin (1920), and Martin Gardner (1957) accept the view of some dowsers that the movement of dowsing rods is the result of unconscious muscular action. Carpenter, William Benjamin. (1877). ''Mesmerism, Spiritualism, &c. Historically & Scientifically Considered.'' New York: D. Appleton and Company. pp. 47–53 Culpin, Millais. (1920). ''Spiritualism and the New Psychology: An Explanation of Spiritualist Phenomena and Beliefs in Terms of Modern Knowledge''. London: Edward Arnold. pp. 34–43 Gardner, Martin. (1957). ''Fads and Fallacies in the Name of Science''. Dover Publications. pp. 101–115. This view is widely accepted amongst the scientific community. Hyman, Ray. (2003)

Quackwatch. French, Chris. (2013)
"The unseen force that drives Ouija Boards and fake bomb detectors"
The Guardian. The dowsing apparatus is known to amplify slight movements of the hands caused by a phenomenon known as the ideomotor response: people's subconscious minds may influence their bodies without consciously deciding to take action. This would make the dowsing rod susceptible to the dowsers' subconscious knowledge or perception; and also to confirmation bias.Hyman, R; Vogt, E. Z. (1968).

The Skeptic's Dictionary.

Pseudoscience

Dowsing is in all other respects considered to be a pseudoscience. Regal, Brian. (2009). ''Pseudoscience: A Critical Encyclopedia''. Greenwood. pp. 56–57. Pigliucci, Massimo; Boudry, Maarten. (2013). ''Philosophy of Pseudoscience: Reconsidering the Demarcation Problem''. University Of Chicago Press p. 38. Radford, Benjamin. (2013)
"Dowsing: The Pseudoscience of Water Witching"
Live Science.

Psychologist David Marks in a 1986 article in ''Nature'' included dowsing in a list of "effects which until recently were claimed to be paranormal but which can now be explained from within orthodox science." Specifically, dowsing could be explained in terms of sensory cues, expectancy effects, and probability.

Science writer Peter Daempfle has noted that when dowsing is subjected to scientific testing, it fails. Daempfle has written that although some dowsers claim success, this can be attributed to the underground water table being distributed relatively uniformly in certain areas. Daempfle, Peter. (2013). ''Good Science, Bad Science, Pseudoscience, and Just Plain Bunk: How to Tell the Difference''. Rowman & Littlefield Publishers. p. 115.

In regard to dowsing and its use in archaeology, Kenneth Feder has written that "the vast majority of archaeologists don't use dowsing, because they don't believe it works."

Psychologist Chris French has noted that "dowsing does not work when it is tested under properly controlled conditions that rule out the use of other cues to indicate target location."

Water dowsers often achieve good results because random chance has a high probability of finding water in favorable terrain.
