Unfortunately for him, Michel Gauquelin allowed his work to be tested by a French Committee which resulted in a statistical comparison that revealed no predictive value in Michel Gauquelin’s work.
However, that is what science does -- allows for new theories to be tested to determine if they can predict results when the tests are duplicated by others.
Of course, astrologers will ignore any scientific results that demonstrate that astrology is bunk.
