>Edit: ok, devil's advocate. Maybe it IS that. How then, does a humans subconscious know where a pipe is buried below ground without any visible indication? it doesn't, but it does a bang-up job of removing the failed attempts from recent memory since the experience of a failure is less rewarding. after a few days of dowsing rod practice you'll only remember the successes intensely, because the failures will be routine and mundane.
