Medical doctors who feel threatened by alternative medicine like acupuncture and homeopathy, have tried try to disprove their effectiveness by testing it the way they would test new allopathic medication. Thus they find what they are looking for: alternative medicine does not work (the way traditional medicine works.) That patients get well is irrelevant.
These doctors do not see that in different fields of science different sets of laws are applicable. Their method of testing is like proving eye contact is not a form of communication, because it does not obey the rules of grammar!
