The DiSC^® Model of Behavior was first proposed in 1928 by William Moulton Marston, a physiological psychologist, in his book Emotions of Normal People. Marston made a deliberate decision to focus only on psychological phenomena that were directly observable and measurable through objective means. From his research, Marston theorized that the behavioral expression of emotions could be categorized into four primary types, stemming from the person’s perceptions of self in relationship to their environment. These four types were labeled by Marston as Dominance (D), Inducement (I), Submission (S), and Compliance (C). He created a model that integrated these four types of emotional expression into a two-dimensional, two-axis space.
