Many of us know a basic history of the DISC Assessment, but did you know that theory behind the four quadrants of personality actually date all the way back to 444 B.C.?

It was Empodocles in 444 B.C. who first wrote a theory of the four quadrants of personality style.  He recognized that people seemed to act in four distinctly different ways, but believed that it was external, environmental factors that affected this.  These elements are Fire, Earth, Air, and Water.

In 400 B.C. Hippocrates redefined these four quadrants as Choleric, Sanguine, Phlegmatic, and Melancholy.  He also recognized the four different types of behavior, but he believed the reason behind it was our internal fluids.

It wasn’t until 1921 that Carl Gustav Jung re-examined these four quadrants and types of behavior, this time contributing the difference to the way we think and process information.  His four styles were Thinking, Feeling, Sensation, and Intuition.

William M. Marston, in 1928, published the book “Emotions of Normal People”, developing what we know and use as the DISC Personality System.  He redefined these four quadrants of behavior as predictable traits that we act out in our every day lives, which are both internal and innate, but also largely impacted by our external environment.  This leads us to our current four quadrants of Dominance, Influence, Steadiness, and Compliance.  In the 1940′s it was Walter Clark who actually developed the first DISC Assessment and Personality Profile.
