The DiSC model sorts workplace behaviour into four styles: Dominance, Influence, Steadiness and Conscientiousness. Its foundation is psychologist William Moulton Marston‘s 1928 book Emotions of Normal People; today’s best-known version, Everything DiSC, is published by John Wiley & Sons. It is widely used to talk about communication styles, but it is a different tool from the research-based Big Five.

02
Score eight scales
Wiley's current assessment scores eight scales around a circle, asking extra questions where answers are unclear.
03
Plot a dot
The result is a dot on a circular map: the direction shows the style, the distance from the centre shows how strong it is.
04
Talk about differences
Reports describe each style's priorities and how to work with other styles.
Where you see it today
From four boxes to a circle
Wiley’s research report for Everything DiSC describes a circular map divided into 12 styles, with an adaptive test that asks extra items when answers are unclear (Wiley, 2026). The modern product is less a four-way label than a position on a continuum.
Personality in AI models
Researchers gave standard personality questionnaires to 18 language models and found that, under some prompting set-ups, the results were reliable and valid, and that a model’s personality could be shaped along chosen traits (Serapio-García et al., 2023). Style is now something you can set, not only measure.
Hiring decisions
For predicting job performance, the stronger evidence base belongs to the Big Five. A meta-analysis (Barrick and Mount, 1991) found conscientiousness related to performance across all the occupational groups studied. Using DiSC to screen candidates is a much weaker bet than using it to discuss how people work together.
Teams that include AI agents
Many AI assistants now let users choose a tone, from brief and direct to warm and detailed. Teams that already use DiSC language can apply it to how they configure agents and how agents hand work to people.

How to use it
Use DiSC to start conversations about working styles, not to label people.
Do not use it to hire, promote or fire; use validated, job-related assessments for those decisions.
Read the style as a tendency on a continuum, and check it against how the person actually works.
Agree on how each style prefers to get information, such as headline first or detail first.
Apply the same language when you set the tone and hand-off rules for AI agents on the team.
The Business Engineer lens
As agents take on part of the work, the useful question shifts from which style a person has to how people and agents should divide and hand off tasks. The Business Engineer looks at personality as something now designed into AI products, with commercial consequences.
Dominance, Influence, Steadiness and Conscientiousness, four behavioural styles first described by William Moulton Marston in 1928.
Who publishes the DiSC assessment?
The best-known version, Everything DiSC, is published by John Wiley & Sons.
Is DiSC valid for hiring?
It is designed for discussing workplace behaviour; for predicting job performance the Big Five has a stronger research record, so DiSC is a weak basis for hiring decisions.
Can AI models have a personality like DiSC styles?
Research shows language models' responses to personality tests can be measured and shaped, so a style can be set on purpose.

BUSINESS MODEL
What is the DiSC model?
The DiSC model was based on research conducted by Dr. William Moulton Marston in 1928 while he was writing the book The Emotions of Normal People. Marston’s subsequent emotional and behavioral theories were inspired by the work of Swiss psychiatrist Carl Jung. The DiSC model is a tool used to measure one’s personality and behavioral style. The first self-assessment tool based on Marston’s research was developed in 1956 by industrial psychologist Walter Clarke.
Marston distilled his work into four distinct personality styles which comprise the DiSC acronym.

Definition
DescriptionThe DiSC Model is a psychological theory and assessment tool designed to understand and measure human behavior, particularly in a workplace or organizational context. It categorizes individuals into four primary personality styles: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C).
Development
DescriptionThe DiSC Model was developed by psychologist William Moulton Marston in the 1920s, and it has since evolved and gained popularity as a tool for self-awareness, team building, and leadership development. It was further refined by John Geier in the 1970s.
Key Concepts
Description– Dominance (D): Individuals with a dominant style tend to be assertive, results-oriented, and focused on achieving goals. – Influence (I): People with an influence style are sociable, persuasive, and enjoy working with others. – Steadiness (S): Steadiness style individuals are patient, cooperative, and value stability. – Conscientiousness (C): Those with a conscientiousness style are analytical, detail-oriented, and focused on quality and accuracy.
Assessment Tool
DescriptionThe DiSC assessment typically involves a questionnaire or survey that respondents complete to determine their primary and secondary DiSC styles. The assessment provides insights into an individual’s behavioral preferences, communication style, and tendencies in different situations.
DiSC Profiles
Description– D-Style (Dominance): D-styles are often seen as assertive, direct, and goal-oriented. They excel in leadership roles and enjoy challenges. – I-Style (Influence): I-styles are outgoing, enthusiastic, and skilled at building relationships. They thrive in roles involving teamwork and communication. – S-Style (Steadiness): S-styles are known for their patience, reliability, and ability to maintain stability. They excel in support roles and value cooperation. – C-Style (Conscientiousness): C-styles are detail-oriented, analytical, and highly organized. They excel in roles that require precision and accuracy.
Understanding
DescriptionThe DiSC Model helps individuals and teams better understand their behavioral tendencies, preferences, and communication styles. It provides insights into how people approach tasks, interact with others, and handle challenges. It emphasizes self-awareness and adaptability.
Implications
Description– Improved Communication: Understanding DiSC styles enhances communication by allowing individuals to tailor their messages to the preferences of others. – Enhanced Team Dynamics: DiSC promotes effective collaboration by recognizing and valuing diverse styles within teams. – Leadership Development: DiSC can inform leadership development programs by helping leaders adapt their styles to different situations and team members.
Benefits
Description– Enhanced Self-Awareness: DiSC assessments promote self-awareness, helping individuals recognize their strengths and areas for growth. – Conflict Resolution: DiSC aids in resolving conflicts by providing strategies to navigate differences in styles. – Team Productivity: Teams that understand DiSC styles can leverage individual strengths, leading to improved productivity.
Drawbacks
Description– Simplification: Critics argue that the DiSC Model oversimplifies complex human behavior and may not capture the full depth of individual personality. – Validity Concerns: Some question the scientific validity and reliability of the DiSC assessment. – Stereotyping: There is a risk of stereotyping individuals based on their DiSC style, which can lead to misunderstandings.
Applications
Description– Workplace Training: DiSC is widely used in workplace training programs, including leadership development, conflict resolution, and team building. – Recruitment: Some organizations incorporate DiSC assessments into their recruitment processes to assess cultural fit and team dynamics. – Personal Development: Individuals use DiSC for personal growth, improving relationships, and career planning.
Examples
Description– A manager with a dominant (D) style may benefit from adapting their communication approach when working with team members who have influence (I) or steadiness (S) styles. – A sales team that understands DiSC styles can tailor their sales pitches to better resonate with different customer profiles. – During a team-building workshop, team members discuss their DiSC profiles and explore how they can collaborate more effectively based on their styles.
Understanding the DiSC model
The DiSC model is a tool used to measure one’s personality and behavioral style.
The first self-assessment tool based on Marston’s research was developed in 1956 by industrial psychologist Walter Clarke.
The tool, which measured one’s natural (unconscious) and adjusted (conscious) behavioral style, ultimately morphed into the DiSC model itself.
The DiSC model is practical and simple to understand and implement. For this reason, it is a popular choice with employees who want to improve how they respond to difficult situations as well as rules and procedures.
The model also clarifies how individuals like to influence others and their preferred pace.
The two basic behavioral drivers of the DiSC model
While not part of Marston’s initial research, it is widely accepted that two motivators drive individual behavior:
Motor drive (pace drive) – motor drive is the pace at which individuals prefer to operate. Extraverted people tend to move fast, talk fast, decide fast, and may be impatient. Introverted people speak and move more slowly and employ a cautious and deliberate approach. They tend to think before speaking or acting.
Compass drive (priority drive) – compass drive describes whether someone is task-oriented or people-oriented. Task-oriented individuals focus on data, logic, and projects, while people-oriented individuals are interested in experiences, relationships, interactions, and feelings.
Note that these motivators are not absolutes, with most individuals embodying both types of drivers to varying degrees.
The four components of the DiSC model
Marston distilled his work into four distinct personality styles which comprise the DiSC acronym.
The lowercase “i” is used to differentiate the official trademark held by John Wiley & Sons, Inc., from other interpretations of the model.
With that said, the four personality styles are
Dominance (D) – confident, demanding, outspoken, and sometimes brutally honest. These individuals are results-oriented and holistic thinkers.
Influence (i) – open, trusting, enthusiastic, and energetic. These individuals like to influence or persuade others.
Steadiness (S) – cooperation, dependability, patience, sincerity, and loyalty. These individuals are cool, calm, and collected and do not like to be rushed.
Conscientiousness (C) – quality, accuracy, competency, and expertise. These individuals are detail-oriented, fear being wrong, and enjoy their independence.
No style is more desirable than the others and, like the two motivators we outlined above, individuals will exhibit a mix of all four styles in their lives.
Instead, the DiSC model clarifies one’s comfort zone – or the style they tend to gravitate toward the most.
Based on this information, the individual can understand their tendencies or preferences and adjust their behavior to relate to others more effectively.
Key takeaways
The DiSC model is a tool used to measure one’s personality and behavioral style. The first iteration of the model was released in 1956 and based on research conducted by William Moulton Marston 28 years earlier.
There are two main drivers of behavior. The first is motor drive, which describes the preferred pace at which one likes to operate. The second driver, compass drive, pertains to whether one focuses on logic and data or people, feelings, and relationships.
Marston distilled his work into four distinct personality styles which comprise the DiSC acronym. These include dominance, influence, steadiness, and conscientiousness. No style is more desirable than the others and most will embody all four over their lives.
Key Highlights
Origins of the DiSC Model: The DiSC model was developed based on research conducted by Dr. William Moulton Marston in 1928 while working on his book “The Emotions of Normal People.” Marston’s theories were influenced by Swiss psychiatrist Carl Jung’s work.
Purpose of the DiSC Model: The DiSC model is a tool used to assess personality and behavioral styles. It helps individuals understand themselves and their preferences, improving their responses to various situations, rules, and procedures.
Development and Evolution: The first self-assessment tool stemming from Marston’s research was created in 1956 by industrial psychologist Walter Clarke. This assessment measured natural and adjusted behavioral styles, leading to the development of the DiSC model.
Practicality and Popularity: The DiSC model is known for its practicality and ease of implementation. It helps individuals enhance workplace productivity, teamwork, and communication. Over a million people take the self-assessment each year.
Two Basic Behavioral Drivers:
Motor Drive (Pace Drive): Refers to the preferred operating pace. Extraverted individuals tend to be fast-paced and decisive, while introverted individuals are slower and deliberate.
Compass Drive (Priority Drive): Describes whether someone is task-oriented or people-oriented. Task-oriented individuals focus on logic and projects, while people-oriented individuals value relationships and interactions.
Four Components of the DiSC Model: Marston’s work led to the identification of four distinct personality styles represented by the DiSC acronym:
Dominance (D): Confident, results-oriented, and holistic thinkers.
Influence (i): Open, enthusiastic, and focused on influencing others.
Steadiness (S): Cooperative, patient, and dependable, valuing stability.
Conscientiousness (C): Detail-oriented, quality-focused, and independent.
Balanced Personality Styles: No single style is better than the others. Individuals exhibit a mix of all four styles, and the DiSC model helps individuals identify their comfort zones and adjust their behavior for effective interactions.
