The well-educated like to mock astrology; I've done it myself. But today over lunch, Robin Hanson convinced me that it's unfair to do so. There's nothing wrong with studying the predictive power of astrological signs. The only problem is concluding that astrological signs HAVE predictive power. In short, the problem is not astrology, but astrologers who habitually publish bogus results.
Thus, a scientist of unimpeachable integrity could write an astrology column. It would just be a little monotonous, because every day, it would make the same prediction twelve times in a row: "Expect a typical day."
