Two Workplace Favorites, Two Different Lenses
DISC and MBTI are the two most commonly used personality assessments in organizational settings. Millions of professionals take them annually for hiring, team building, leadership development, and career planning. But despite their shared popularity, they measure fundamentally different aspects of personality. Choosing between them — or understanding how to use both — starts with knowing what each one actually captures.
What Does DISC Measure?
DISC was developed from the work of psychologist William Moulton Marston, who in 1928 proposed four primary behavioral dimensions. The modern DISC assessment measures:
- Dominance (D): How you respond to problems and challenges. High-D individuals are direct, results-oriented, and competitive. Low-D individuals are more cautious, diplomatic, and collaborative.
- Influence (I): How you interact with and persuade others. High-I individuals are enthusiastic, optimistic, and socially active. Low-I individuals are more reserved, reflective, and task-focused.
- Steadiness (S): How you respond to pace and consistency. High-S individuals value stability, patience, and reliability. Low-S individuals prefer variety, change, and multitasking.
- Conscientiousness (C): How you approach rules, procedures, and quality. High-C individuals are analytical, detail-oriented, and quality-focused. Low-C individuals are more big-picture, flexible with rules, and willing to improvise.
DISC focuses on observable behavior — what you do, not why you do it. This makes it immediately practical for workplace applications. Take the free DISC assessment on JobCannon to discover your behavioral style.
What Does MBTI Measure?
The MBTI measures cognitive preferences — how you naturally process information and make decisions. Its four preference pairs are:
- Extraversion (E) vs Introversion (I): Where you direct and receive energy
- Sensing (S) vs Intuition (N): How you take in information
- Thinking (T) vs Feeling (F): How you make decisions
- Judging (J) vs Perceiving (P): How you organize your outer life
MBTI goes deeper than behavior to address cognitive style. Two people might behave similarly in a meeting (both speaking up assertively) while having completely different cognitive processes driving that behavior (one processing logically, the other intuitively).

Key Differences at a Glance
What They Measure
DISC measures behavior — your observable actions and tendencies in workplace situations. MBTI measures cognition — your internal preferences for processing information and making decisions. Think of DISC as "how you act" and MBTI as "how you think."
Stability Over Time
MBTI types tend to be more stable because cognitive preferences change slowly. DISC profiles can shift depending on context — many people have a different DISC style at work versus at home. This contextual flexibility is actually a feature, not a bug, since DISC is designed to assess situational behavior.
Number of Types
DISC produces profiles along four dimensions with no fixed type count, though practitioners commonly identify 12-16 style combinations. MBTI produces 16 distinct types. Both systems allow for nuance beyond their primary categories.
Workplace Application
DISC is the go-to for communication training, sales coaching, and team dynamics because it directly addresses observable behavior. MBTI is preferred for career counseling, leadership development, and strategic team composition because it addresses cognitive strengths and blind spots.
When to Choose DISC
DISC is your best choice when you need to:
- Improve communication with specific colleagues or clients
- Understand your sales or negotiation style
- Build more effective team dynamics
- Adapt your management approach to different reports
- Prepare for a role that requires specific behavioral competencies
DISC shines in situations where immediate behavioral change is the goal. Because it measures what you do rather than who you are, it provides actionable steps you can implement immediately.
When to Choose MBTI
MBTI is your best choice when you need to:
- Explore which careers align with your cognitive strengths
- Understand why certain types of work energize or drain you
- Develop your less-preferred cognitive functions for growth
- Build a shared language for team cognitive diversity
- Explore deep patterns in how you process the world
MBTI excels when the goal is self-understanding and long-term career alignment rather than immediate behavioral adaptation.
Using Both Together
The most powerful approach is taking both assessments and comparing results. DISC tells you how you behave at work; MBTI tells you why. An INTJ (MBTI) might have a high-D DISC profile at work but express it through strategic thinking rather than aggressive competition. An ESFP (MBTI) might show a high-I DISC profile, expressing their cognitive style through enthusiastic social engagement.
When the two profiles seem to conflict, that is often the most interesting finding. It may indicate that you are adapting your natural style to meet workplace demands — a common and potentially exhausting pattern that career planning should address.
For the fullest picture, complement both with the Big Five personality test, which adds the Neuroticism dimension that neither DISC nor MBTI captures, and provides the strongest scientific validation of any personality framework.
Which Assessment Do Employers Prefer?
It depends on the industry and purpose. Sales organizations and customer-facing companies tend to prefer DISC for its direct behavioral focus. Consulting firms, tech companies, and leadership programs tend to prefer MBTI for its cognitive depth. Increasingly, forward-thinking organizations use both: DISC for team communication and MBTI for strategic role placement.
Neither test should be used as a hiring gate — responsible organizations use personality assessments for development and team optimization, not for screening candidates in or out.
