Actually, those things are being used; just perhaps in ways you wouldn't recognize.
For instance, most hospitals (in California, anyway) now have at least one alternative practitioner on staff -- homeopathy, hypotherapy, reiki, etc. Financial and business planners regularly use astrology, tarot, and other modalities; they just don't usually tell you about it. (Remember Ronald Reagan?) And military organizations certainly use curses and hexes - that is, mind tricks and manipulations that have a win/lose intention, which is what a curse or hex is.
