You're torn between a DISC test and an MBTI test, or you took one at work and now you're wondering what the other one would have told you. The short answer: they don't answer the same question. DISC describes how you behave with others; MBTI sorts your preferences into one of sixteen types.
The long answer is more useful, because it keeps you from reading one as if it were the other. We'll look at where they come from, what each one actually measures, what the research says about their reliability, and how to choose based on what you want to get out of it. The studies cited are listed at the bottom of the page.
Two Tools Born From Two Different Theories
They're often lumped together, but their histories never actually cross.
DISC comes from William Moulton Marston. In Emotions of Normal People (1928), this American psychologist described four ways of reacting to your environment, depending on whether you perceive it as favorable or hostile, and whether you feel in a position to master it or not. These four reactions became the four letters: Dominance, Influence, Steadiness, Conscientiousness (also called Compliance). One crucial point: Marston never built a questionnaire. The first tests based on his model appeared in the 1940s, and dozens exist today, each with its own set of questions. We tell this story in detail in William Moulton Marston: The History of DISC.
MBTI comes from Carl Gustav Jung. In Psychological Types (1921), Jung proposed a theory of psychological preferences. Katharine Cook Briggs and her daughter Isabel Briggs Myers turned it into a questionnaire starting in the 1940s. Unlike DISC, MBTI is a single, precise instrument, a registered trademark published by one company, The Myers-Briggs Company.
This difference in status matters: whenever you read "DISC says that", you should always ask "which DISC test?" When you read "MBTI says that", you're talking about a single questionnaire.
What Each One Actually Measures
DISC describes a behavior style. It's concerned with what other people see of you: your pace, how you make decisions, persuade, cooperate, and check details. The result is a dominant style out of four, together with the weight of the other three. On Profilia, the test has 25 questions: each one presents four groups of adjectives, and you pick the one that describes you best.
MBTI sorts preferences. It combines four pairs of opposites: Extraversion or Introversion (where you draw your energy from), Sensing or Intuition (how you gather information), Thinking or Feeling (how you decide), Judging or Perceiving (how you organize yourself). Four pairs of two gives sixteen types, labeled with four letters like ENFP or ISTJ.
One detail changes how you should read the result. According to the Myers & Briggs Foundation, which promotes its use, MBTI sorts results into preference categories: you're classified on the extraversion side or the introversion side, and the test doesn't measure how strongly you lean that way. The same source contrasts this approach with trait-based models, like the Big Five, which places each person on a continuous scale.
The Comparison, at a Glance
| DISC | MBTI | |
|---|---|---|
| Original theory | Marston, 1928 | Jung, 1921 |
| First questionnaires | 1940s, by people other than Marston | 1940s, by Briggs and Myers |
| What it describes | Your behavior style with others | Your preferences: energy, perception, decision-making, organization |
| Result | One dominant style out of 4, with the weight of the others | One type out of 16, labeled with 4 letters |
| Answer format | Choice among several statements (4 groups of adjectives on our test) | Choice between two statements |
| Who publishes it | Public model, dozens of different tests | A single instrument, published by one company |
| Hiring use | Not recommended, for lack of evidence that it predicts job success | Against its own code of ethics |
What the Research Says About MBTI
Because MBTI is a single questionnaire, research can evaluate it directly, and its findings are clear-cut.
It largely overlaps with the Big Five. In 1989, psychologists Robert McCrae and Paul Costa compared MBTI to the five-factor model. Their conclusion: the four MBTI scales measure aspects of four of the five major personality dimensions. In other words, one of the five Big Five dimensions has no MBTI scale. And their data didn't support the idea that preferences are true categories.
People don't naturally sort into two camps. If types existed as natural categories, scores would cluster into two bumps, one per pole. A study of about 12,000 people (Bess and Harvey, 2002) shows that the bimodality reported by earlier work came from the scoring method, and that scores actually cluster toward the middle. In 2003, Arnau and colleagues looked for natural categories in three Jungian questionnaires, including MBTI, using statistical methods built for exactly that purpose: they didn't find any. Preferences behave like continuous dimensions.
What this means for your type. If you score close to the middle of a scale, you can flip from one side to the other between one sitting and the next, even though your personality hasn't changed. Each scale, taken on its own, stays stable: the publisher reports test-retest reliability coefficients of 0.81 to 0.86 for the four scales, based on 1,721 adults who retook the test 6 to 15 weeks apart. That figure applies to each scale on its own, and it doesn't say how many people end up with the exact same four-letter code.
Its own code of ethics restricts how it can be used. The MBTI code of ethics is explicit: using its results to screen job candidates is unethical practice.
What the Research Says About DISC
DISC poses a different problem: since every publisher built its own questionnaire, there's no single "DISC" to evaluate, and independent research is scarcer. We gathered what it shows, and what it doesn't, in Is DISC scientific?. Two points matter for this comparison.
It also overlaps with the Big Five, to a degree. A 2013 study (Jones and Hartley) found significant but modest links between a DISC test and the five-factor model, for example between the Influence style and extraversion.
Forced-choice format describes a balance, not a score. When every answer gives a point to one style at the expense of the others, the total is the same for everyone. Psychologist L. E. Hicks showed as early as 1970 that these scores describe the balance of styles within one person well, but don't lend themselves to comparisons between two people. So read your profile as your own combination, not as a ranking against your colleagues. To see how profiles actually break down, we published ours, along with our methodology, in DISC personality types percentages.
Do DISC and MBTI Measure the Same Thing?
A study published in 2025 had the same 130 Korean students take both questionnaires (Kim and colleagues, JMIR Human Factors). The authors found significant correlations between the two, for example between the Thinking or Feeling dimension of MBTI and the Dominance style of DISC. The coefficients they highlight range from 0.17 to 0.38 in absolute value. With a sample that small, treat it as an order of magnitude, not a final measure.
In practical terms: even the strongest link (0.38) leaves more than 85% of the differences between people on one scale unexplained by the other. The two tools overlap without matching up. That's also why the charts circulating online, the kind that claim "ESTJ equals Dominance", should be taken with caution: we haven't found any correspondence table validated by a study.
Which One Should You Choose?
Instead of asking "which one is better", ask yourself: what do I actually want to do with it?
Choose DISC if you want to work better with others. You can remember four styles after a single meeting, and they give you a simple vocabulary for talking about what's getting in the way: "I need us to get to the point", "I need time to check things over". This is where DISC is most at home: on teams, in management, or in client relationships. To go deeper on each style, read understanding DISC profiles.
Choose MBTI if you want to think through your preferences. Its vocabulary (introversion, intuition, judging) is widely used in coaching and personal development. Keep in mind what the research says: your type is a marker on continuous scales, not a box you're locked into.
Choose the Big Five if you want the most-studied model. It's the reference framework in personality research: it covers all five dimensions, including one that MBTI doesn't measure, and it places you on scales rather than in categories. Our free Big Five test explains how it works.
And nothing stops you from taking the first two: they shed light on different facets, as long as you don't try to translate one into the other. If you're also torn between several versions of DISC, our comparison of DISC and Everything DiSC sorts that out, and the complete guide to the DISC model brings together all our articles on the subject.
Take the Test and Make Up Your Own Mind
The simplest way to compare is to see yourself in one of the models. Our DISC test has 25 questions, takes about 5 minutes, and your result shows up right away, no sign-up required.
And if you want to find out where you stand on the five major personality dimensions, the Big Five test is there too.
Frequently asked questions
Is MBTI more reliable than DISC?
That's not quite the right question, because DISC isn't a single test. For MBTI, the publisher reports good retest stability for each scale (coefficients of 0.81 to 0.86), but studies show preferences are continuous, so a score near the middle can flip sides. For DISC, reliability depends on which questionnaire you use. Neither one is the reference model in personality research: that's the Big Five.
Can you convert an MBTI type into a DISC profile?
Not reliably. The 2025 study that had the same people take both tests found modest links, with coefficients of 0.17 to 0.38. We haven't found any validated correspondence table: an ENTJ isn't necessarily Dominant, and someone with a Dominant profile isn't necessarily an ENTJ.
Why does my MBTI type change from one time to the next?
Because the test splits continuous scales into two. If you sit near the middle of a pair, say between extraversion and introversion, a small difference in your answers is enough to flip your letter. Your personality hasn't changed, it's the boundary between two categories that runs close to you.
Can DISC or MBTI be used for hiring?
The MBTI code of ethics considers it unethical to use its results to screen candidates. For DISC, it's not recommended either: we found no meta-analysis showing that a DISC profile predicts job success, and our test is designed for personal reflection and team discussion. We cover this in detail in Is DISC scientific?.
Does DISC come from Jung, like MBTI?
No. MBTI is based on Jung's theory of types (1921). DISC comes from William Moulton Marston's model (1928), which describes reactions to your environment, not psychological preferences. The two were born a few years apart, but from different ideas.
Should you take both tests?
It's not necessary, but it makes sense if your questions are different: DISC for how you interact at work, MBTI for your preferences. If you want a single measure backed by research, start with the Big Five instead.
