What is DISC?

Robert Rohm describes it best.

A Powerful Way to Understand People Using the DISC Personality Concept

by Robert A. Rohm, Ph.D.

  • 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 that 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.

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.

Based 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.
