Most facets of the human personality are already charted out. People fit into the same criteria (even beyond zodiac signs) There is a set number of profiles that everyone fits into. And scenarios that predict human response and behavior. Were actually not very different from eachother. Nature still made all of us from the basic mold.

The Highest science of predictabilty I would say is the Planets and their positions. They send out electromagnetic pulses that effect the ionic field.
One trained can look into your natal positions, do a dual wheel chart over your chart, check the degrees of the transits and predict what you will do and where you will go tomorrow. It is a advanced science with some Secret Societies. Its used for countries and people and events, especially with a astro cartography overlay.

The Freemasons also measured the energy pulses of the rising planets and the closest proximity planets called bright morning stars. This imparted a higher probability of high intellect and musical gifts.
