Should we truly accept ancient rituals and beliefs without testifying? Of course not. Numerous examinations can be proceeded to disqualify wrong attitudes; drowsing is an subtle issue that could be considered phony. According to the professor’s thoughtfulness, drowsers are not validated enough to be called experts in seeking a proper point for water digging.
Extra ordinary claims need extra ordinary evidences to make verified conclusions. It is argued that drowsers can detect and recognize the emitted wave from water; hence, they are capable of finding a suitable spot to make a well. Based on the result of sensitive detectors, water does not emit any spectacular electromagnetic wave.
Therefore, the existence of the mentioned wave has not been found scientifically. As an inferrence based on statistical data, the probability of finding a qualified spot is equal for both who are drowsers and who are mediocre. Furthermore, imperical experiences have indicated that drowsers can’t surpass normal people in certain controlled conditions. That’s why hiring drowsers does not seems to be a profitable or intellectual decision.
Overall, it can be inferred that drowsers are just the same as normal diggers in efficiency. Although they have thought their techniques affect the results, the scientific experiments contradict. Thus no vital need to hire a drowser would be felt.
