Many people have asked why is Keirsey Temperament Theory not known broadly as “it should be.”
For a long time, I couldn’t give a good answer.
The answer is: “It’s a Slow Idea.”
My father outlines “The History of Madness” in his lectures. And the Wholistic Theory of Madness is a slow idea, its roots going back to over a century with my father adding the idea of Temperament in the last half century. Fast Ideas about “madness” have been around since Homo Sapens possessed language.
The roots of the Idea of Keirsey Temperament also go back to ancient times.
In addition, there is the idea of: Slow Ideas <=> Fast Ideas
The root of this idea appeared just recently, thanks to Atul Gawande.
