As a science type, I encourage you to not turn off your brain to astrology, Feng Shui, crystal power, and other crap.
Instead, test it formally, with double blinds, hoping that it works (so you don't subconsciously suppress data). Then if you find something, have others duplicate your work. That's the scientific method.
Done, Done, done and done. There have been _endless_ double blind tests of alternative medicine and other magic beans. All of them show that the accuracy (if even testable) is no better than blind chance.
The reason "us science types" are so dismissive of these things is we're sick of re-debunking ideas we finished with _decades_ ago.
I've looked at the listing, and it's right! -- Joel Halpern
