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. [...] A large-scale test of persons born less than five minutes apart found undisputable hints of the similarities predicted by astrology . Meta-analysis of more than forty controlled studies suggests that astrologers are performing significantly better than chance on basic tasks such as predicting extraversion. More specifically, astrologers who claim to use psychic ability perform notably better than those who do not. The possibility that astrology might be relevant to consciousness and psi cannot be denied anymore as such influences are very strong and noticeable.
