Birthdate psychology: a new look at some old data

Area of Science:

• Psychology
• Astrology
• Human Development

Background:

• Earlier research indicated significant differences in California Psychological Inventory (CPI) "Femininity" scores among individuals born under different astrological zodiac signs.
• The observed pattern of scores remained unexplained and provocative.

Purpose of the Study:

• To explore alternative perspectives on the unexplained correlation between astrological signs and CPI "Femininity" scores.
• To analyze discrepancies between astrological sign classifications and measured femininity.
• To investigate potential environmental or developmental factors influencing this correlation.

Main Methods:

• Analysis of existing data on CPI "Femininity" scores and astrological birthdates.
• Comparison of observed score patterns with traditional astrological sign classifications.
• Speculative consideration of environmental influences on prenatal and neonatal development.

Main Results:

• A continuous trend was observed: higher "Femininity" scores correlated with birthdates from July 24 to January 20.
• Lower "Femininity" scores correlated with birthdates from January 21 to July 23.
• Discrepancies were noted between astrological sign "masculine/feminine" labels and measured CPI "Femininity" scores.

Conclusions:

• The study highlights an unexplained link between birth timing (astrological signs) and adult personality, specifically femininity.
• Potential environmental factors such as climate, diet, or geomagnetic events during critical developmental periods may influence personality traits.
• Further research is needed to elucidate the mechanisms behind this observed correlation.
