Extended DISC Profiles - I Style

What is the DISC Assessment?

The DISC assessment is based on the work of William Moulton Marston, a psychologist who created the DISC theory. The DISC model centers on four DISC factors known as Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C).

The I Style

The I Style profile, also known as Influence or I type, is one of the four basic DISC types that originated from the William Marston’s DISC Model.

I Styles make up approximately 29% of the worldwide population.


I personality styles are talkative, sociable, optimistic and lively. They are people-oriented, spontaneous, energetic and enthusiastic. I styles tend to be positive and good at influencing others.

I styles can also be inattentive to details, overly talkative and emotional. They may over-promise because they are so optimistic and are eager to be popular. Others may perceive I styles as somewhat careless, impulsive and lacking follow-up.


I Styles love to talk about people and positive subjects. They tend to avoid negative issues and are not always direct in their approach to communication.

When communicating with I Style individuals, focus on feelings and emotions, be positive, move quickly, but spend time chatting.
