Are you sure you have good reasons to do what you do and to say what you say ?

I read in several posts on this forum that you use dowsing to decide what is true and what is false and also to decide what to do and what to avoid.

Why do you believe in dowsing ?

What is the evidence that dowsing work reliably ? Do you have any reference of a scientific report or at least a personal experiment made with an objective view ?

Thanks,
