The CIA used Remote Viewers during the Iranian Hostage Crisis way back when. Crazy, but true. Then again, how much different is Remote Viewing from GPS anyway? (especially in the late 70’s)
With regards to Astrology and Tarot Card reading, I think you can trust that nonsense EXACTLY as much as you can trust a financial industry expert. They are both just con artists looking into the future, a future where they have emptied your pockets.
In certain cases one can sue a financial adviser for negligence – if they fail to exercise due diligence or lack the necessary skill to offer advice and one suffers damages from relying on that advice. It would be interesting to try the same thing with an astrologer (as opposed to an action for fraud).
