A Powerful Way To Understand People Using the DISC Personality Concept

by Robert A. Rohm, Ph.D.

This Is Just the Beginning!

One of the dangers of learning about DISC is that you may think you now understand all there is to know about it. We have just scratched the surface of the dynamics involved in personality styles. Did you know there are not just four personality styles? We identify 41 specific personality blends that are all very different. Even within the 41 personality blends, there can be a wide variety of nuances.

Each Person Has Unique Personality Traits

Each person’s perspective is built into who they are. Some people call it “personality,” and some refer to it as “temperament.”

Ever notice how different your family and friends can be from you? If you are like me, you have asked yourself, “Why did they do that?” or “What were they thinking?” The starting point of understanding people is to realize and accept one simple fact: everyone is not like you!

Have you ever said the same thing to two people and received two totally different reactions? How can saying the same words produce such different results? Each person “heard” you differently based on his or her personality style! You said the same thing, but what they “heard” was different.

Different is not bad, it is just different! A lack of understanding of ourselves and others can lead to real problems such as tension, disappointment, hurt feelings, unmet expectations, and poor communication. As you know, it is hard to work with a problem, especially if you do not understand what is going on inside the mind of another person.

There Is a Simple Way to Understand People!

The good news is that there is a simple key to understand how people behave and how they are motivated. We call the concept the DISC Model of Human Behavior. This concept will allow you to unlock the mystery behind developing good people skills and creating better relationships. You will be able to use what you learn in this introduction to reduce conflict, improve productivity, and relate with others more effectively.

"Understanding how one can be a task oriented and the other can be people oriented, helped me understand how to communicate differently in the other person's communication style. Saved my marriage!"

Some Background on the DISC Model of Human Behavior

Twenty-four hundred years ago, scientists and philosophers, most notably Hippocrates, began to recognize and categorize differences in behavior that seemed to follow a pattern.

Since then, many psychologists and scientists have explored behavioral patterns. Dr. William Marston wrote The Emotions of Normal People in 1928 after earning his doctorate from Harvard University. Marston theorized that people are motivated by four intrinsic drives that direct behavioral patterns. He used four descriptive characteristics for behavioral tendencies which are represented by four letters of the alphabet: D, I, S, and C. Thus the concept of
“DISC” was introduced.

Building on a “Wellness” Model

Many behavioral models focus on what is wrong with a person to identify “personality disorders.” The DISC model is based on normal behavior, not abnormal behavior. DISC is a “wellness model” that is objective and descriptive rather than subjective and judgmental. Therefore, DISC is a practical way to understand yourself and those around in the common settings of everyday life.

A Positive Approach

The DISC wellness model is a good framework for understanding people. DISC should be used in a positive way to encourage a person to be his or her best—not as a way to “label” someone.

Healthy, positive relationships come from having an accurate understanding of yourself and others. DISC is a powerful tool for obtaining a new appreciation for our personality styles and their effect on our everyday lives.

We apply the DISC model with four main ideas that allow it to be used appropriately as an effective and encouraging tool:

    We use a positive approach to highlight and encourage a person in his or her strengths.
    We use a positive approach to address a person’s possible blind spots without assuming a weakness exists.
    We recognize that each person has a unique blend of all the major personality traits to a greater or lesser extent.
    We recognize that behavioral patterns are fluid and dynamic as a person adapts to his or her environment.

    I have a saying that, “Your strengths should carry you while your blind spots should concern you.” Being able to identify and articulate your strengths can be very empowering. Being able to identify and uncover blind spots can also be very empowering! The next few pages can be the start of your own empowering discovery process.

    So, now that you know where the DISC concept came from and the importance of having a positive, flexible approach, let’s take a look at the Model of Human Behavior using the DISC!

    The DISC Model of Human Behavior

    The DISC Model of Human Behavior is based on two foundational observations about how people normally behave:

    Observation #1: Some people are more outgoing, while others are more reserved. You can think of this trait as each person’s “internal motor” or “pace.” Some people always seem ready to “go” and “dive in” quickly. They engage their motor quickly. Others tend to engage their motor more slowly or more cautiously.

    Observation # 2: Some people are more task-oriented, while others are more people-oriented. You can think of this as each person’s “external focus” or “priority” that guides them. Some people are focused on getting things done (tasks); others are more tuned in to the people around them and their feelings.

    With both observations, we want to emphasize that these behavioral tendencies are neither right or wrong or good or bad. They are just different. We are simply identifying normal behavior styles. People have different styles, and that is okay. We represent these two observations:

    Four Major Personality Traits

    In review, we have four behavioral tendencies to help us characterize people:


    Everyone has some of all four of these tendencies at different times and in different situations. However, most people typically have one or two of these tendencies that seem to fit them well in their everyday behavior. And, on the other hand, one or two of these tendencies usually do not fit them well, and these tendencies may even seem “foreign” to their approach to life. The balance of these four tendencies shapes the way each person “sees” life and those around them. By combining the two previous diagrams, we can show four basic quadrants of the circle as shown below. Thus, four basic personality traits emerge from our diagram corresponding to the four quadrants of the circle (in clockwise order):

    Outgoing and task-oriented (upper left quadrant)
    Outgoing and people-oriented (upper right quadrant)
    Reserved and people-oriented (lower right quadrant)
    Reserved and task-oriented (lower left quadrant)

    Next, we will add descriptive terms for each of the four main personality types that emerge in the diagram. The descriptive terms will begin with D, I, S, and C.

    Describing Each Personality Style

    There are four different personality types with four different priorities. Notice the letters D, I, S and C appear in the four quadrants of the circle in the figure below. You will also notice that descriptive terms have been added in each of the four corners of the diagram. Now we can further describe each of the four main personality styles:

    D-I-S-C Descriptive Terms

    1. The Dominant “D” type. An outgoing, task-oriented individual will be focused on getting things done, accomplishing tasks, getting to the bottom line as quickly as possible and “making it happen”! The key insight in developing a relationship with this type of person is respect and results.

    2. The inspiring “I” type. An outgoing, people-oriented individual *to interact, socialize, and have fun. This person is focused on what others may think of him or her. The key insight in developing a relationship with this type person is admiration and recognition.

    3. The Supportive “S” type. A reserved, people-oriented individual will enjoy relationships, helping or supporting other people, and working together as a team. The key insight in developing a relationship with this person is friendliness and sincere appreciation.

    4. The cautious “C” type. A reserved, task-oriented individual will seek value, consistency, and quality information. This person focuses on being correct and accurate. The key insight in developing a relationship with this individual is trust and integrity.

    Summarizing the DISC Traits

    D stands for the Dominant type, which is outgoing and task-oriented.
    I stands for the Inspiring type, which is outgoing and people-oriented.
    S stands for the Supportive type, which is reserved and people-oriented.
    C stands for the Cautious type, which is reserved and task-oriented.

    What Is Your PQ (Personality Quotient)?

    We spend years in school developing our intelligence to effectively use our mind. Developing our unique personality to effectively use our behavior is just as vital to successful living. Your intelligence quotient, or IQ, measures your intelligence. Your Personality Quotient, or PQ, refers to your ability to understand yourself and others for effective communication and teamwork. Studies have shown that technical skill, beginning with intelligence and developed through education and experience, accounts for only 15 percent of success in the workplace. The other 85 percent of workplace success comes from people skills! These skills are developed through learning better ways to behave and interact.

    The Elevator Test: Which Type Are You?

    The elevator doors are about to close on an eager rider who is trying to get on the elevator. Four people are already inside the elevator. One of the people in the crowded box is in a hurry and does not want to wait (outgoing and task-oriented). There is also a bubbly, energetic passenger who holds the door open while greeting the newcomer (outgoing and people-oriented). A third rider is happy either way and smiles while waiting patiently (reserved and people-oriented). The final passenger is concerned as she calculates the weight to see if the elevator can handle another person (reserved and task-oriented).

    While not perfectly scientific, this scenario illustrates the Dominant (outgoing / task-oriented) person who is focused on getting somewhere fast; the Inspiring (outgoing / people-oriented) person who is energized by all the interaction; the Supportive (reserved / people-oriented) person who reacts calmly and tries to get along regardless; and the Cautious (reserved / task-oriented) person who wants to make sure the added person doesn’t exceed the weight limit! As you can see, there were four different people who responded to the same event in four very different ways!
