Abstract: Many astrologers attribute a successful birth-chart reading to what
they call intuition or psychic ability, where the birth chart acts like a crystal ball.
As in shamanism, they relate consciousness to a transcendent reality that, if true,
might require a re-assessment of present biological theories of consciousness. In
Western countries roughly 1 person in 10,000 is practising or seriously studying
astrology, so their total number is substantial. Many tests of astrologers have
been made since the 1950s but only recently has a coherent review been possible.
A large-scale test of persons born less than five minutes apart found no hint of
the similarities predicted by astrology. Meta-analysis of more than forty controlled
studies suggests that astrologers are unable to perform significantly
better than chance even on the more basic tasks such as predicting extraversion.
More specifically, astrologers who claim to use psychic ability perform no better
than those who do not. The possibility that astrology might be relevant to consciousness
and psi is not denied, but such influences, if they exist in astrology,
would seem to be very weak or very rare.
