The Genesis of the DISC
Few researchers have dared to explore the uncharted territory of everyday human behaviour and psychology quite as thoroughly as William Marston, a Harvard-trained psychologist and academic. In 1928, Marston published a book titled "The Emotion of Normal People", which laid the groundwork for the personality profiling tools that would follow decades later.
How successful was William Marston?
Ironically, Marston's work stayed largely unnoticed for decades, gathering dust on library shelves for close to fifty years. It wasn't until the early 1970s, with the rise of the computer industry, that his theories were rediscovered and turned from academic curiosity into a practical management tool — what we now know as DISC.
The Tenets of Marston's Theory
Marston's theory rests on two basic axes. The first is the introvert–extrovert spectrum, recognising that most people sit somewhere between the two extremes rather than at either end. The second axis looks at how a person perceives their environment — as broadly friendly or broadly hostile — which in practice translates into whether they lean task-oriented or people-oriented.
Cross these two axes and Marston's theory opens out into a spectrum of profiles, each represented by a colour and a letter — D, I, S, and C. In our practice, the DISC Assessment is a widely used tool for both team building and individual coaching.
Delving into the DISC
Looking more closely at the DISC model means exploring the four primary behavioural styles it represents. It remains a widely used tool in psychology and organisational development for understanding — and to some extent predicting — human behaviour at work.

The first letter, D, stands for Dominance.
Symbolized by the color red, it represents energy, passion, straightforwardness, and dynamism. Individuals with a high level of D in their DISC profile are often seen as assertive, decisive, and goal-oriented.
I is the second letter, representing Influence.
Colored yellow, it stands for happiness, positive thinking, creativity, and an easy-going nature. These individuals are typically extroverted, enthusiastic, persuasive, and excellent in roles that require collaboration and team dynamics.
S, the third letter, signifies Steadiness.
Its color green signifies tranquility, nature, calmness, and willpower. Individuals with a high level of S are often seen as reliable, patient, and prefer a steady pace in their work and personal lives.
Finally, the last letter, C, stands for Compliance.
Marked by the color blue, it signifies control, organization, and rules. These individuals prize structure and reliability and are often meticulous, analytical, and detail-oriented.
The Practicality of DISC
What does this mean in practical terms? Importantly, DISC is not a test to pass or fail — it's a profiling tool that helps you understand yourself and the people around you. It offers a reference point, a shared framework for understanding how different people respond to challenge, influence, rules, and pace.
Ideally, a balanced team features a genuine mix of all four DISC profiles. A management team made up entirely of D profiles might excel at fast decision-making but struggle with the fine detail and process. Conversely, an all-C team might thrive in a structured, rule-driven environment but find dynamic innovation or flexible problem-solving harder going.
The diversity of DISC profiles within a team fosters a richer, more adaptable work environment. Each profile brings a unique set of skills and perspectives to the table, making the team as a whole more robust and versatile.
The purpose of Marston Theory
In conclusion, Marston's DISC theory holds a mirror to our behavioral patterns, helping us understand ourselves and others better. It’s a tool we can use to enhance our interpersonal skills, foster a harmonious work environment, and attain personal and professional success.
Whether you're a D, I, S, or C, remember, every individual is a unique combination of these traits. Embrace your strengths, work on your weaknesses, and use the DISC as a guide to navigate your journey to success. After all, as Marston himself embodied, it's our individual differences that make us uniquely human.
FAQ
What is the primary purpose of using the DISC methodology in the workplace?
The primary purpose of using DISC in the workplace is to improve communication and team dynamics. By understanding the predominant personality traits across a team, managers can adapt their leadership style and communication approach to boost collaboration and productivity, rather than relying on a single one-size-fits-all style.
How does the DISC model differ from other personality assessment tools like the Myers-Briggs Type Indicator (MBTI)?
Unlike the MBTI, which categorizes individuals into one of 16 personality types, the DISC model focuses on four primary personality traits (Dominance, Influence, Steadiness, Conscientiousness) and allows for more fluidity in assessing personality. It emphasizes observable behaviors rather than underlying psychological preferences.
Can individuals' DISC profiles change over time, or are they relatively stable?

While an individual's core DISC style tends to remain relatively stable, people can adapt their behavior and exhibit traits from other categories in response to different situations and life experiences. This adaptability makes the DISC model a dynamic tool for understanding behavior.
