William Moulton Marston: The Creator of the DISC Model and His Lasting Impact on Business Success
Introduction
In 1928, an American psychologist, lawyer, inventor, and comic book writer, William Moulton Marston, introduced a groundbreaking theory of human behaviour that has since transformed personal and professional development. His DISC model, first outlined in his book Emotions of Normal People, is now one of the most widely used tools in human resources worldwide. This blog explores the life of William Moulton Marston, the creation of the DISC model, and how it continues to influence modern business practices today.
William Moulton Marston: A Pioneering Innovator in Psychology
Early Life and Education
Born in 1893, William Moulton Marston had a varied and exceptional career. After graduating from Harvard University with a bachelor’s degree in 1915, he went on to earn his law degree in 1918 and a Ph.D. in psychology in 1921. This rich academic background played a crucial role in shaping his innovative work in psychology and beyond.
Contributions to Psychology
Marston’s greatest contribution to psychology was his 1928 book Emotions of Normal People. In this work, Marston identified four primary emotional responses linked to behavioural traits, setting the foundation for what would later become the DISC model. Unlike many psychologists at the time, Marston focused on the normal, everyday behaviour of people, rather than on pathological conditions. This approach to understanding human behaviour laid the groundwork for the DISC model, which remains an essential tool in modern business.
Beyond Psychology: The Inventor and Comic Book Creator
Marston’s talents extended far beyond psychology. He invented an early prototype of the polygraph or lie detector, using systolic blood pressure tests to measure deception. But perhaps his most widely recognised creation was the iconic comic book character Wonder Woman, who personified truth, justice, and the belief in human goodness—a reflection of Marston’s own values.
The DISC Model: A Revolutionary Theory of Human Behaviour
The Four DISC Profiles
Marston’s DISC model categorises human behaviour into four primary profiles, each reflecting an individual’s dominant emotional and behavioural traits:
Dominance (D) – Individuals who are assertive, competitive, and results-driven.
Influence (I) – Sociable, enthusiastic, and persuasive communicators.
Steadiness (S) – Calm, patient, reliable, and empathetic individuals.
Compliance (C) – Detail-oriented, analytical, and structured thinkers.
By understanding these four profiles, businesses can better predict how individuals may react in different situations, leading to improved interactions and performance.
Emotions of Normal People: Marston’s Groundbreaking Work
In Emotions of Normal People, Marston argued that everyone exhibits traits from all four of the DISC profiles, though in varying degrees. This insight into human nature is the foundation of the DISC assessment, enabling organisations to understand and predict behaviour, leading to enhanced communication, teamwork, and conflict resolution.
