Without commenting on the issue of scientific study of the veracity of Astrology, I'd like to point out that both western Astrology and western Psychology come from the same intellectual history. Theories of the four elements, the humours, etc. have been around for several thousand years and however much contemporary psychology as a discipline would like to divorce itself from them, they are its foundation. This is particularly true for some followers of Jung, who explicitly used Astrological and related thought as the basis of his theories (not of course adopting them in whole). It is no coincidence that Astrology and the *Jung*-Meyers-Briggs typology have overlaps, in fact, it would be quite surprising if they didn't. It is another question whether one sees that as a strength of Astrology, or a weakness of Jungian typologies, or neither.
