What is DISC?

DISC aids in self-success by providing a clear framework for making conscious behavior adjustments while communicating with others.

DISC is an assessment tool used to measure one’s personal behavior in the form of a 7-10-minute questionnaire. The use of DISC provides many benefits to individuals and organizations. The DISC model explained below has been in existence for nearly 100 years and has proven to change individual behavior and workplace efficacy for the better.

History of DISC

DISC is a theory of human behavior turned into a model based on the foundations of Carl Gustav Jung’s work. The DISC model was created in 1928 by William Moulton Marston to increase self-awareness and better understand other people. This model aids in self-success by providing a clear framework to make conscious decisions about how to adjust behavior while communicating with others. The DISC model is powerful because it is easy to learn, understand, and use because it identifies four behavioral styles of individuals: D Style, I Style, S Style, and C Style.

Defining the styles of DISC assessment

DISC Behavior Model


The D-Style is the most aggressive and assertive of the four styles. D-Styles tend to be quite competitive and results-oriented. As a result, others may perceive D-Styles as being too aggressive, blunt, and even rude. Under pressure they can appear to have a lack of concern for others. D-Styles want to be in charge and have the power. A few of the well-known D-Styles include Simon Cowell, Kanye West, and Alec Baldwin.


I-Styles are outgoing, social, and talkative, and like to be the center of attention. They like to interact with others and meet new people. They do not like to focus on details, or spend a lot of time by themselves. Others tend to perceive I-Styles as very friendly, enthusiastic and animated. Some well-known I-Styles include Jim Carrey, Ellen DeGeneres, and Amy Poehler.


S-Styles are steady, calm, and laid back. While they do like interaction with other people, they are more reserved and less animated than I-Styles. S-Styles prefer things to remain the same because changes and surprises threaten their sense of security. Family and friends tend to be very important to S-Styles. They often defend their own group or team almost emotionally; fairness and justice are very important to S-Styles. A few well-known S-Styles include Sarah Jessica Parker, Halle Berry, and Mahatma Gandhi.


C-Styles are the most analytical of the four behavioral styles. C-Styles can be very detail-oriented, focusing on the facts, information, and proof. They are comfortable working alone and are the most reserved of the four styles. C-Styles are logical and methodical in their approach. Some well-known C-Styles include Bill Gates, Al Gore, and “Monica” from friends.

It is important to remember that when studying the four DISC styles that you keep in mind that no DISC style is better or worse, and that all styles have strengths and development areas-they just happen to be different.
