Which DISC Personality Type is The Most Common (and most rare)?

Our organization sees tens of thousands of assessments completed every single month.

When we combine our assessment data with our technology partner, Assessments 24×7, we see hundreds of thousands of assessments completed yearly.

With this pool of data, we have a unique perspective to understand how learners respond to the DISC questionnaire. One of the questions we were curious to answer was what is the most common DISC Personality type?

In order to answer this question, we needed to segment all of the data in a couple of ways. First, this data is from 2024 and only includes assessment results from English speakers (more on this later). Finally, this data only looks at Graph 3 reports and doesn’t look at Natural or Adaptive styles.

So, what is the most common DISC Style we found based on these parameters?

The IS Style is the most common DISC Personality Type, and it was identified 18% of the time out of a sample of 530,842 completed DISC Assessments in 2024.

Conversely, the D-Personality Type is the most rare DISC Style. Only 2% of all assessment respondents sampled received this DISC Style.

In this graph, you will see the data for all possible identified combinations. In this article, we will review data for each of the four primary DISC Styles and insights for the 12 DISC Personality Types.

DISC Personality Types Chart

Before we discuss the data surrounding the most rare and common DISC styles, we must first understand each personality type.

Below is the DISC Personality chart with a review of each style. You can compare the results of each DISC Style with a brief overview of each personality type.

The DISC Personality chart is not comprehensive of the details of each style. For more information about each style, please read our guide to the 12 DISC Personality Types.

D-Style Direct, daring, and natural problem solvers.	DI-Style Fast-paced, persuasive, and results driven.	DC-Style Assertive, determined, and excels at critical thinking
I-Style Magnetic, enthusiastic, and collaborative	ID-Style Influential, upbeat, and fast-paced.	IS-Style Welcoming, easygoing, and trusting
S-Style Consistent, calm, and supportive.	SC-Style Risk-averse, modest, and reflective.	SI-Style Welcoming, conflict-averse, supportive
C-Style Methodical, precise, accurate.	CS-Style Attentive, cautious, and reliable.	CD-Style Logical, resolute, and efficient.

With this information in mind, let’s dig into the most common and rare DISC Personality profiles!

The D-Personality Type is The Rarest DISC Profile

The D-personality type is known for being dominant, decisive, and able to take charge. Ironically, it is the rare DISC Personality Type (more on that below) to be assigned in our data sample.

Here is how often each combination of the D-Personality was assigned in 2024 out of all DISC assessments completed:

DI – 4%
DC – 2%
DS – 2%
D – 2%

Why is the D Personality Type so rare?

The D-Personality type (Dominant Style) is the majority style in only 10% of all completed DISC assessments in our 2024 data sample. Compared to the other DISC Personality Types, those with the D-Style are in sparse company.

Why is the D-Personality type the most rare DISC style? This question is perplexing, given that many famous and well-known political people have this style.

The answer is likely due to social desirability.

Social desirability is a bias where people answer questions about themselves in a manner they feel makes them look more favorably by others.

The D-Personality Type is viewed as less favorable in societies that prize community over individuality. If an individual with this background answers a DISC assessment, they may favor more desirable answers to lessen how dominant their personality is.

In this data sample, we only examined English-speaking respondents, and a majority of those assessments were completed in the United States of America. Even though America is known for being independent and self-sufficient, it is evident that traits like being supportive are more desirable than being direct.

How to connect better with the D-Personality Type

While there are fewer D-Style people than the other DISC personality Types, those with the Style are likely well known because of their dominant personality.

Whether you want to improve relationships with someone at work or in your personal life, it’s easy to connect with this style if you understand their behavioral needs and stresses.

How to Connect with the D-Style at Work

Every workplace has challenges. Potentially, workplaces have more challenges than ever due to technology or because more generations of people are working together than ever before.

Fortunately, those with the D-Style love challenges. Allow them to take charge of a challenge and provide different solutions that they feel could be viable.

I-Personality Type Ts The Most Common DISC Personality Type

The I-Personality type is the most assigned DISC Style across our data from 2024.

The I-Personality Type makes up almost 40% of all assigned styles. Below are the percentages of how often each I-Style is assigned:

IS – 18%
ID – 7%
I – 7%
IC – 6%

Why is the I-Personality Type so common?

The story of the I-Personality Type is similar to the D-Personality type but in reverse. Whereas the D-personality is the most uncommon style, many people likely identify I-Style characteristics due to social desirability.

The I-Style associated behaviors are:

Enthusiastic
Inspiring
Optimistic
Persuasive
Sociable
Trusting

For many, it might be tempting to identify with these characteristics even when they don’t match the reality of one’s personality. It’s important to note that social desirability is considered when researching the overall reliability and accuracy of DISC assessments, but its effect is hard, if not impossible, to determine.

One way to determine if you are completely accurate in determining your DISC Style if you have the I-Personality Type is to take the DISC 360 assessment. This assessment asks you to complete the DISC Questionaire along with having close colleagues, friends, or family members answer the same questions about you. The results allow you to see how others see your personality which can be very eye-opening.

How to connect better with the I-Personality Type

Those with the I-Style prefer close relationships and enjoy working with others. They are social, optimistic, and trusting.

They fear the disapproval of others. This could cause them to go above and beyond in relationships compared to other styles.

How Businesses can leverage those with the I-Style at Work

Gallup’s annual workplace survey asks a very simple question that might seem odd at first glance:

Do you have a best friend at work?

This question, is extremely important to understand organizational health and also effectiveness. In organizations where employees have a best friend at work, they have longer tenure, are more productive, and have better customer interactions.

When considering these factors, those with the I-Style can play a large role in helping organizations come together and socialize. This alignment helps those individuals engage in behavioral needs while helping the organization promote friendships.

Which S-Personality Type Is The Second Most Common DISC Personality Type

When looking at everyone who completed a DISC assessment in 2024 and was given a version of the S-Personality Type, the most common S-style was the SC-Personality type.

Here is the complete data for this group:

SC – 15%
SI – 8%
S – 3%
SD – 1%

How is an SD-Style possible?

While very few people have received this style, it is possible. This style was only assigned to 5,700 people in 2024.

We don’t consider it one of the 12 standard DISC Personality Types because it’s so rare. In other DISC assessments, like Everything DiSC, the assessment process actually forces a learner to choose one style over the other by asking a single, two-choice question that features the behaviors of either style. The person would receive an S or a D-Style, but their graph would be close to even for either style.

So, what does this style mean?

Ultimately, these individuals are very good at switching between two very different behaviors.

When coaching these individuals, we will ask questions to help them uncover more about themselves:

Do you feel like a chameleon at work where it’s easy to be dominant and supportive?
Are you able to flip quickly between either style?
Is this something you have always been good at, or did you develop these behaviors out of necessity?

At times, it’s evident that a certain situation forced a person to take on two competing behavioral styles and it is now part of their personality profile.

How to connect better with the S-Personality Type

The S-Style or Steadiness personality seeks a stable and consistent environment. For this reason, they are often the peacemakers and bring a sense of calmness to the environment where they work and live.

This style can be very patient, but their fear of losing security or stability can force them to make questionable decisions.

How to connect with the S-Style at work

The S-Style is likely the workplace listener, coach, or guide. Because of their calmness and patience, they are often excellent listeners.

It’s important not to limit the potential of those with this style. They may not be the first ones to raise their hand to lead a project, but they will often be on the backend of any project, ensuring they have contributed to its success.

The C-Personality Type Is The Third Most Common DISC Personality Type

Next to the D-Personality Type, the C-Style is the second least common DISC style. The CS Style, however, is the second most common style, with 17% of assessment respondents in 2024 identifying with this style.

Below is the complete data for this group:

CS – 17%
CI – 3%
C – 2%
DC – 2%

Thoughts on the CS-Style and Today's Workplace

A majority of the U.S. workforce does not work in technology. However, a concept from the tech world has quickly taken over the rest of the world: Moore’s Law.

Moore’s Law is an observation of how the number of transistors doubled on each new computer chip each year at a steady rate since the 1960s.

Because transistors allow computer chips to process and compute information, Moore’s law has become a catch-all phrase to explain the speed of change we are experiencing as a society.

While the CS-style isn’t the most common DISC Style, it’s a very close second. This style also works at the slowest pace.

As you think about your workplace or your team, consider those with this Style and the amount of stress that fast-moving changes could cause this style. While the reason for workplace stress is hard to identify, this correlation does stand out. Leaders may want to consider how many of their employees have this style and ensure that any proposed changes allow time for this style to digest and work through the changes.

How to connect better with the C-Personality Type

Those with the C-Personality strive for accuracy. This need to showcase their accuracy drives them to be precise and focus on the details.

In addition, their need for accuracy plays into why they work at a slower pace than other DISC Styles. After all, if you are moving too quickly, you may make a mistake.

How to connect with the C-Style at work

One of the ironies of the speed of change our society is experiencing is that those who slow down and focus on the details are able to help groups use the new technology more effectively.

When leveraging new technology, consider allowing those with the C-Style a few days to really unpack everything that is included and ask them to present their findings to their team or the organization as a whole. You will be impressed with what they can discover and how to apply it to everyone’s work.
