DISC is the four quadrant behavioral model based on
the work of William Moulton Marston Ph.D. (1893 - 1947) to examine the
behavior of individuals in their environment or within a specific situation.
DISC looks at behavioral styles and behavioral preferences. Marston, the
father of the DISC, was a graduate of Harvard University. Among his
contributions in his profession Marston was a consulting psychologist,
researcher and author of five books, which he either wrote or co-authored.
He was published in the American Journal of Psychology, The Encyclopedia of
Psychology, and The Encyclopedia Britannica.
Marston’s 1928 “Emotions of Normal People”, introduced DISC theory to the public. He defined four categories of human behavioral styles, types or temperament, now know as "D" for Dominance, "I" for Influence, "S" for Steadiness and "C" for Conscientious.
Dominance: Direct & Decisive. These are the people that tend to be strong-minded. They are strong-willed people who enjoy challenges, taking action, and immediate results. The bottom line is their focus tends to be on the bottom line and results.
Influence: Optimistic & Outgoing. These individuals tend to be very social "people people" who prefer participating on teams, sharing ideas, and entertaining and energizing others.
Steadiness: Sympathetic & Cooperative. These people tend supportive, helpful and team players. They prefer being behind the scene, working in consistent and predictable ways. They are often good listeners.
Conscientiousness: Concerned, Cautious & Correct. These people are often focused on quality. They plan ahead, check for accuracy, and utilize systematic approaches to problem solving.
The real power of DISC comes from its ability to interpret the relations between these four quadrants. For example where a highly Dominant person has an equally high level of Influence, they will behave quite differently to an equally Dominant individual without that Influence. The factors combine like this to provide (theoretically) around one million different 'profiles' (that is, combinations of the four factors).
Using this information, DISC can be used to describe a person's general approach, including their motivations and dislikes, strengths and weaknesses, and some of the basic assumptions they make about other people. It can also go far in helping to predict how a person will react to a specific set of circumstances.
