Abstract
After conducting extensive research between 1981 and 1986, Dr Geoffrey Dean concluded that no evidence was found that astrological factors correlated with psychological profiles. However, in 2017, using Dean’s original dataset of 288 subjects with extreme scores on the Eysenck Personality Index (EPI), I found a significant correlation between Eysenck’s personality types (extraversion, introversion, neuroticism, and emotional stability) and the astrological elements (Currey, 2017). Subsequently, in 2022 Dean and his co-authors criticised my methods and conclusion. They claim that the significant findings could be explained by the subjects’ false self-attribution, whereby individuals adapt their personality or manipulate their responses to personality tests to align with the traits associated with their Sun Signs. The authors persist in this claim, despite the absence of evidence indicating any knowledge or interest in astrology among the subjects. Furthermore, in his original paper, Dean asserts the impossibility of false responses given the inclusion of a lie detector response within Eysenck’s test. This current paper aims to eliminate all reasonable doubt by demonstrating that the positions of the Moon and the Ascendant (acknowledged by Dean as not susceptible to false self-attribution) independently hold strong significance (p = .006; r = .13) according to a binomial sign test. When combined with the Sun sign (the third but more controversial theoretical factor), the probability becomes p < .0001; r =.15. The likelihood of such a result occurring by chance is less than one in ten thousand.
