What is


The DISC assessment is a widely used tool in the field of psychology and human resources that helps individuals understand their behavioral preferences and communication styles. Here's a brief overview of the history of DISC assessments:

The History


The Start.

The DISC model traces its roots back to the 1920s when psychologist William Moulton Marston developed the theory. Marston was a Harvard-trained psychologist, lawyer, and inventor, best known for creating the comic book character Wonder Woman. His work on the DISC theory aimed to understand and categorize human behavior.

Developments & Evolution.

Marston's research led to the identification of four primary personality traits, represented by the acronym "DISC":

  • Dominance (D): Emphasis on control, power, and assertiveness.
  • Influence (I): Emphasis on communication, sociability, and enthusiasm.
  • Steadiness (S): Emphasis on patience, persistence, and teamwork.
  • Conscientiousness (C): Emphasis on precision, accuracy, and systematic approaches.

Over the years, various researchers and practitioners have refined and adapted the DISC model. Numerous DISC assessments and tools have been developed to help individuals and organizations gain insights into behavioral styles for personal and professional development.

Application in Business

The DISC model gained popularity in the business world as a valuable tool for improving communication, teamwork, and leadership. Many organizations use DISC assessments for team building, conflict resolution, and employee development.

Assessment Tools

There are several DISC assessment tools available today, each with its own methodology and approach. These assessments typically involve a series of questions or statements that individuals respond to, leading to a profile that highlights their primary DISC traits

Limitations and Continued Popularity

While DISC assessments provide valuable insights, it's important to note that they are just one tool among many for understanding human behavior. People are complex, and behavior can vary in different contexts.

The enduring popularity of DISC assessments speaks to their effectiveness in helping individuals and teams enhance communication, collaboration, and overall effectiveness.


The history of DISC assessments reflects a journey of understanding and categorizing human behavior, with ongoing applications in personal and professional development. As with any assessment tool, it is important to use DISC results as a starting point for self-awareness and improvement rather than as a rigid categorization of individuals.
