Why dowsing is a con:

I have seen people do it and convence others it was real. It was very easy to get caught up in. The problem was there is no evidence it works at all.
@hankster Prayers work too according to many. "It works" is not evidence. It takes standing up to science to be evidence. Show me peer reviewed studies.
If you were holding the dowsing rod and it suddenly plunged down, would that be evidence?
@WilliamFleming not unless the experiment was repeatable with anyone that used it, and it could be proven to work anywhere anytime. That is science. The next great step would be a discovery that explains why it happens.
I took part in a dowsing process once. I went from being a total skeptic to believing. It was a shocking experience to be holding the forked branch and have it plunge down. I have since started having doubts though because I experimented with it under controlled conditions and couldn’t get it to work, or the effect was very flukey.
I still retain an open mind. There are a lot of things in nature that are not understood.
Drilling for water better be far far away from fracking that causes earthquakes and poisons ground water for miles around
