Although DiSC® describes four styles (D, I, S, and C), the model is two-dimensional.
The first dimension runs along the vertical axis, from fast-paced at the top, and moderate pace at the bottom. It depicts an individuals activity level, their energy. The second dimension runs along the horizontal axis, ranges from skeptical on the left, to accepting on the right. People whose dot fall to the left are expected to be more questioning and cynical. While people who fall to the right are expected to be more trusting of others.
The two dimensions of DiSC® create four quadrants which many people are familiar with and refer to as their DiSC® style.
In additions to the four quadrants, DiSC® drills down deeper into twelve segments to give you a more accurate view of your DiSC styles. Many individuals have a primary and secondary style. So instead of just being a "D," an individuals style may be an "iD" which demonstrates that their primary style is Influencing, however, given a certain situation, they have the tendency to respond with the D (dominance) style also.
With practice, we all have the ability to utilize all four styles of the DiSC® model.
