The DISC assessment is a powerful tool that has been used for decades to help individuals and organizations better understand human behavior. Developed by psychologist William Marston in the early 20th century, the DISC model categorizes behavior into four primary personality traits: Dominance, Influence, Steadiness, and Conscientiousness. This assessment has since become a cornerstone in fields such as psychology, business, and personal development. In this article, we will delve into the DISC assessment, exploring its history, components, applications, and its impact on individuals and teams.

The Four Personality Traits

D personalities are driven by challenges and are typically motivated by achieving goals.

People with an influential personality are sociable, persuasive, and enthusiastic.

History and Development

The DISC assessment’s foundation can be traced back to William Marston’s research on human behavior, which led to the creation of his book “Emotions of Normal People” in 1928. Marston’s work laid the groundwork for understanding how people respond to their environment and interact with others.

The modern DISC assessment, as we know it today, was further developed by Walter V. Clarke in the 1950s.

Over the years, the assessment has evolved and is now widely used in various personal and professional contexts.
