Quite right. As far as dowsing is concerned, we need to get away from the ideas of "occult practices", "belief" and the like and just treat dowsing as we do any poorly understood phenomenon that requires systematic study and sound research. Both the New Age folk and the Sceptics have taken on board notions about personal powers and other worldly manifestations, instead of forgetting these and just using systematic experimentation. How lucky it is that Reddish was totally ignorant of the subject and started his studies from scratch, just employing the knowledge he had gained from astrophysics and applying standard procedures of observation and measurement.
