Doubt the ancients in their ideas of Personality, as many do. Ridicule some connection to the stars, but
after 6000 years, spanning many human generations of thinkers, our modern psychologists still come up with the repetitious idea illustrated by the organization of the KOFH Universal. It isn't the stars, but the Human Gene Pool, perhaps.

Whether or not the "psychology" is correct seems immaterial. Though
these many practical applications demonstrate that we can not help but think in this pattern, the point is moot, educationally.
It makes good educational psychology to organize repetitiously because "Order in, Order out."
