D. Clarke et al., ASTROLOGICAL SIGNS AS DETERMINANTS OF EXTROVERSION AND EMOTIONALITY -AN EMPIRICAL-STUDY, The Journal of psychology, 130(2), 1996, pp. 131-140
Astrological theories assume a link between an individual's personalit
y traits and the positions of the sun, moon, and planets in the zodiac
at the moment of birth. Previous research has examined the relation o
f the sun sign to personality traits, but moon and ascendant signs hav
e not been studied in relation to personality traits. The dominance ef
fect of the sun on men and the moon on women has also not been empiric
ally researched. Eysenck Personality Inventory (EPI) scores on extrove
rsion and emotionality were obtained from 190 first-year university st
udents. Date, time, and location of birth were requested, to establish
the positions of the sun, moon, and ascendant in positive, negative,
and water signs for each individual. Multiple t tests showed a signifi
cantly greater mean extroversion score for the group with both the sun
and the moon in positive signs than for the group with both in negati
ve signs. No other differences in means were significant. The findings
generally did not support theories claiming that tendencies toward ex
troversion and emotionality are determined by astrological signs.
