Re-examination of the gender differences of ordinary people, as clalmed by J. F. Ruis

Author: Ertel, Prof. Suitbert
Abstract: J. F. Ruis compared birth frequencies between males and females of ordinary people (Gauquelin data) across planetary sectors and claimed that certain frequencies differed significantly. Since the dates of birth in his male and female sub samples had not been matched, the result might be due to an astronomical-demographical artefact. The present study tries to replicate Ruis’ result using the same data with male and female sub samples matched for date of birth (n+ 7,593) each. Each sub sample was divided using the median birth day as the dividing point, into two successive cohorts. For each cohort the male proportion of births, indicating the gender difference, was determined across 36 sectors of 5 planets. If gender differences exist they should be stable across successive cohorts, but gender differences in the first cohort did not reoccur in the subsequent cohort. This was revealed by correlations. The observed lack of stable differences cannot be attributed to the method since the same method successfully demonstrated stability in identifying Mars-prone professionals and ordinary people. The finding of Ruis is thus most probably due to an astronomical-demographical artefact.
