When analyzing birth charts, astrologers are often struck by certain planets, and they give them more importance. Many astrology authors claim traditional rules of what they call “dominance”, which is placements within a natal chart where the astrological influences of the planets are strongest. Planetary dominance would be the first factor in power, the one that takes precedence and has the most influence helping us considerably increase the accuracy of astrological interpretation.

There are several methods to determine planetary dominance. But none of them has been tested on a large scale and validated. Our goal was to identify the combination of astrological factors allowing us to arrive at the biographical dominance only from the information contained in the astrological chart. 

Therefore, we have designed a protocol to establish dominant planets from biographies by using automated matches between whole charts and biographies, a method that has already demonstrated success (Godbout, 2020). 

To do this, we had each of the ten planets play the dominant role in turn; then, by examining each of the ten portraits thus obtained in Mastro software, we identified the optimal dominance by choosing the portrait that best matched the biography. These biographical dominant planets became targets that were checked for a match with planetary dominance calculated according to rules determined solely from the astrological chart. 

For 189 subjects, if we compare the dominant planets according to our model of Adjusted Planetary Dominance with the dominant planets according to biographies, the success rate obtained could only be achieved by pure chance two out of one million (p < 2.08E-06).
