“For example, a set of twenty-five studies involving five hundred astrologers examined the average degree of agreement between astrological predictions. In social science, such as in psychology, tests that have less than o.8 (i.e., 8o percent) agreement level are considered unreliable. Astrology's reliability is an embarrassingly low o. I, with a variability around the mean of o.o6 standard deviations. This means that there is, on average, no agreement at all among the predictions made by different astrologers.”
