Both among the general public and among archaeologists there is a widespread belief in the presumed abilities of dowsers to locate underground archaeological features. This article reviews the nature of such beliefs as evidenced in published materials from professional archaeologists in the UK. It is found that there is a contradiction between largely privately held convictions that dowsing works and public rejection, caution or silence. An examination of the best available published evidence for the validity of dowsing shows that field tests were badly designed and executed, ignoring important statistical biases and modifying test parameters in order to obtain positive results. These methodological shortcomings are traced to archaeologists' lack of training in controlled test design, and prior belief in the validity of dowsing. Where field tests were properly designed and executed, no evidence for the validity of dowsing was obtained. The article concludes that properly designed tests are entirely feasible, and that it is up to the proponents of dowsing to conduct such tests. *
