Rolling's Four Temperaments

In around 19 80, an american psychologist named David kearcey argued that virtually all humans fall under one of four basic temperaments. Kearcey label these as guardians who value security, order and hard work, artisans who value adventure, artistry or technique, physical beauty and excitement. Idealists, who value harmony with other people, profound experiences and recognition, correspond to house griffendor. rationals are those who value knowledge and understanding complex systems, and would correspond to house ravenclaw. So is it possible that roling drew her inspiration not from plato, but from kersey's four temperaments?
