The DISC Time Line

DISC theory as it is known today stems from millennia of research, development, theorisation and refinement. It all started with a 4 Quadrants model. Originating in Ancient Greece, this original 4 Quadrants model is one of the oldest known bahavioural assessment tools.

C. 400 B.C. – Ancient Greece – Hippocrates develops the first 4 Quadrants model: Consciousness, Emotion, Intelligence, Wisdom.

Many great philosophers and mathematicians like Plato and Aristotle studied and augmented Hippocrates’ lessons. In Greece during the Middle Ages and the Renaissance, scientists continued searching for the basis of human bahaviour.

1913 – Munich, Germany – Fourth International Psychoanalytic Congress

Renowned psychologists such as Carl Jung and Sigmund Freud gathered in Munich to discuss their theories. Jung delivered a lecture on psychological types focused on extraverts and introverts. He later expanded his theory to include early models of personality description. Throughout the 20th century, researchers continued to explore variations of the 4 Quadrants model to try to explain human bahaviour. As an example, Jung's research is the foundation for the Myers Briggs Type Indicators (MBTI).

1928 – United States of America – William Moulton Marston, Ph.D.: The Emotions of Normal People

This Harvard-trained psychologist working at Columbia University dedicated much of his life to the study and enhancement of his 4 Quadrants model. His book outlined his theories and became the foundation for modern DISC assessments. Marston introduced the definitions of DISC. He named the four factors Dominance, Inducement, Submission and Compliance. Though each of the terms has held onto its definition, the acronym has been changed over time to better fit the modern society. DISC, as it is known today, is defined as:


  • Dominance – relating to control, power and assertiveness
  • Influence – relating to social situations and communication
  • Steadiness – relating to patience, persistence, and thoughtfulness
  • Compliance – relating to structure and organisation


1958 – Dr. John Geier Creates the First DISC Assessment

Dr. John Geier bought the rights to Marston's book and created the first DISC Assessment in 1958. In the past 50 years, dozens of bahavioural scientists and assessment companies have been instrumental in reworking the DISC theory and commoditizing Marston’s work. Dr. Geier’s research efforts brought credibility to the theories that Marston espoused in Emotions of Normal People.
