Of 500 people tested only six managed to show dowsing ability slightly above chance. Chance was 12% they achieved 16%. Rubbish results seen as all the dowsers predicted they could do it with more than 90% success.

More recently a scientific study[3] was undertaken in Kassel, Germany, under the direction of the Gesellschaft zur wissenschaftlichen Untersuchung von Parawissenschaften (GWUP) [Society for the Scientific Investigation of the Parasciences]. The three-day test of some thirty dowsers involved plastic pipes through which a large flow of water could be controlled and directed. The pipes were buried 50 centimeters under a level field. On the surface, the position of each 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 agreeing this was a fair test of their abilities and that they expected a 100% success rate. However, the results were no better than what would have been expected by chance.

The contestants agreed to all the procedures prior to the test. They were also allowed to dowse the field with no water running to determine whether there might be any interfering natural phenomena, and to dowse the field with water running in a known pipe to verify (subjectively) their sensitivity to it. Similar tests were designed for contestants who believed they could find brass or gold. In all, 111 trials were made. There were 15 successes, which is well within the range (around 11) expected by chance.
One of the reasons we know dowsing is bunkum is because it is so very easy to test using double blind methods.
I've offered you a free holiday to the UK to prove your claims before. If you would like to come over and do the bucket test or even the pipe test I'll refund all your expenses including spending money if your successful.
Until then all you have is anecdotal evidence and that shows nothing apart from the fact you find it easy to deceive yourself.
Science may not have all the answers but when it comes to dowsing they do. Its all bunkum.
So I'd have say that it is a technique that has had some exceptionally long historic staying power for something that's as "fake" as some claim it to be.
That is a very silly argument. Stars predicting the future, people being tortured because of witchcraft, throwing salt over shoulder, not passing on the stairs, walking under ladders breaks the holy trinity, history is full of stupid ideas that still persist today.
