What is DISC Assessment?
The DISC assessment is a behavioral profiling tool that measures four primary behavioral traits: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). Developed from the psychological theories of William Moulton Marston in the 1920s, DISC has become the world's most widely used personality assessment in workplace settings.
Unlike other personality tests that focus on what you think or feel, DISC specifically measures how you behave in different situations. This behavioral focus makes it incredibly practical for workplace applications, team building, leadership development, and communication improvement.
Why DISC Assessment Matters
- Improves Communication: Understand how others prefer to receive information
- Enhances Team Performance: Build balanced teams with complementary skills
- Develops Leadership: Adapt your leadership style to different personality types
- Reduces Conflict: Understand and appreciate different behavioral preferences
History & Scientific Foundation
The DISC model traces its roots to Dr. William Moulton Marston, a Harvard-educated psychologist who published "Emotions of Normal People" in 1928. Marston's revolutionary idea was to focus on observable behaviors rather than internal psychological states, making personality assessment more practical and actionable.
Marston's Original Theory
- Behavior is observable and measurable
- People adapt behavior based on environment
- Four primary behavioral factors exist
- Understanding leads to better relationships
