Number two, don't count on me to get your girlfriend turned around. My powers of persuasion are awesome, but experience shows these people are immune to argument. After all, the stars are unthinkably distant, and the planets, an essential part of astrology, revolve around the sun, not the earth. But this is not what astrology buffs want to hear. By this they mean a skilled astrologer can give you genuine insights into your personality.
Many experienced astrologers are pretty fair amateur shrinks.
In the course of a one or two hour consultation they can usually get a good fix on your problems. But to say astrology can be helpful doesn't mean it has any objective validity. The fact is, people who want to believe in astrology will convince themselves it works no matter what. In one study of 22 astrology buffs, half were presented with their real horoscopes and half were presented with fake charts saying the exact opposite. Both groups said their horoscopes were 96 to 97 percent accurate.
