The four DiSC personality types and what they mean

What is DiSC?

DiSC is short for Dominance, Influence, Steadiness and Conscientiousness. These are the four DiSC personality types, or behavioural styles, that it can identify through its testing. We will cover these in more detail later, but first let us go over some history of the test.

The DiSC theory was put forward in 1928 by the American psychologist William Moulton Marston. Originally, it was a categorisation for everyday people rather than a business-focused theory, evidenced by it being published in the book Emotions of Normal People.

In the mid-1950s, psychologist Walter Clarke created the Activity Vector Analysis, which was essentially a checklist for job applicants to show their qualifications. Around a decade later, this idea was built on to create the DiSC assessment we know today.

Although it was not initially intended for use in the workplace, it fits in quite well with how we psychologically profile people, particularly leaders. DiSC assessments can also be used on team members, managers and various other roles in the workplace, because it is always useful to have an understanding of how people work with each other.

How does DiSC work?

A DiSC assessment consists of a set of questions, and the number varies between tests. These typically offer behavioural scenarios that the respondent answers with their most likely response. The test uses these to place respondents into one of four behavioural styles.

Typically, a DiSC assessment will end with a behavioural profile that will explain results in more detail. For example, the Everything DiSC assessment for leaders we use generates a twenty-three-page profile that explains what a respondent’s answers mean in relation to specific questions. It is designed to provide actionable insights into behaviour to make people better at what they do.

Although a level of self-awareness is helpful when going into a DiSC assessment, you will certainly have some when you finish it. Being asked to look at your behaviour, and think about what you would do, is a great way to make things click like they have not before.

As such, a DiSC test is useful for both the people taking it and the company they work for. The results discuss what behavioural styles work best together and give explanations of why we choose certain actions. In theory, this can help enhance clarity and create a clearer understanding of expectations.

What are the four DiSC personality types?

Now, let us take a closer look at the four DiSC personality types. Remember, no one is exclusively one style; we are often a blend. However, one style typically dominates. It is also important to note that no single style is better than another.

Dominance (D style): direct, firm and results-oriented

Dominance can sometimes be misunderstood, but it is simply a term to describe individuals who are direct, firm, strong-willed and results-oriented. These leaders are driven by a desire to achieve and thrive on challenges, often taking quick, decisive action.

On the DiSC scale, people with a Dominance style are fast-paced, assertive and dynamic. They prioritise action, results and challenging the status quo, and tend to question ideas to ensure the best outcomes. They focus less on feelings and more on logic and efficiency, aiming for rapid progress and high performance.

In leadership roles, individuals with the D style excel in high-pressure environments where swift decisions and results are crucial. They are natural leaders who thrive when they can set their own pace and push boundaries.

Of course, no behavioural style is perfect, and dominant people do have some weaknesses. As you can probably guess by the adjectives used so far, dominant personalities are not focused too heavily on the people side of things. This is not to say they will not be good leaders, but their focus is more on driving people forward than ensuring everyone is always happy and fully motivated.

A D-style leader’s focus on results can sometimes overshadow their attention to relationships, making empathy and patience areas for development. While they are effective at driving performance, they may need to focus on including others and ensuring team motivation.

Influence (i style): outgoing, enthusiastic and optimistic

As the name suggests, the Influence style is characterised by a focus on people and relationships. Individuals with this style are outgoing, enthusiastic and optimistic, often using their charm and energy to encourage collaboration and inspire their team.

Leaders with an i style tend to be high-spirited, lively and capable of creating a positive, sociable atmosphere. They thrive on expressing enthusiasm and enjoy working in environments where they can motivate others through collaboration and teamwork.

In leadership roles, these individuals shine in people-focused environments, where they can use their social skills to boost morale and encourage creativity. They excel in group settings and are often seen as fun and approachable.

Influential people’s impulsiveness and tendency to prioritise relationships over objectivity can be weaknesses. Leaders with an i style may struggle with follow-through on tasks or providing constructive feedback, making them less effective in high-pressure situations that require critical decision-making.

However, when placed in the right environment, influential styles can thrive in the way they motivate their teams. Their optimism, charm and energy are incredibly useful for teams who might be having difficulty keeping their heads up.

Steadiness (S style): patient, steady and supportive

Steadiness is characterised by patience, humility and a calm approach. Leaders with an S style are often seen as accommodating and even-tempered, providing a stabilising influence in their teams. They focus on creating a harmonious, cooperative environment where everyone feels supported.

People with this style are methodical, tactful and focused on maintaining stability. They value teamwork and support, often prioritising the needs of others. In leadership, they excel in collaborative environments where long-term relationships and cooperation are vital.

However, this focus on others can sometimes work against those classed as steady personalities. They may choose to prioritise the needs and ideas of others over their own, which can impact their personal development and, if left unchecked, their ability to lead. You may find that steady personalities face burnout quicker because they do not value their own needs enough.

Also, as with influencers, steady people can have difficulty facing conflict in the workplace. While they are often more diplomatic than influencers, their desire to accommodate everyone can lead to issues when dealing with disagreements. They may also struggle to motivate a quicker pace for work as key deadlines approach.

Conscientiousness (C style): precise, analytical and systematic

The Conscientiousness style is defined by a focus on accuracy, analysis and systematic processes. People with this style are reserved, precise and logical, often placing great importance on ensuring accuracy and maintaining stability. They tend to question assumptions and prefer environments where they can focus on quality and consistency.

Leaders with a C style are known for their attention to detail and their ability to analyse complex problems before making decisions. They thrive in situations where precision and objectivity are valued, making them ideal for roles that require methodical planning and consistent results.

As you might be able to tell, conscientious people are focused more on actions and results than the people they lead. Similar to dominant personalities, they give less attention to their team members, meaning they may struggle to deal with the empathy side of leadership.

You might also find that they cannot look beyond the data and insist on perfectionism. While this can be helpful in some situations, it can also create tunnel vision that can detract from the overall objective.

Using the DiSC styles to develop leaders

Knowing the four DiSC personality types can be useful for identifying and training effective leaders. Understanding how styles work best helps with placement in departments that need those specific qualities, hopefully resulting in you getting better results from both the leaders themselves and the teams they lead. If you are asking which style makes the best leader, we answer that in which DiSC type is best for leadership.
