Is there a most depressed MBTI type? What the research says

Lists of the “most depressed MBTI types” and charts of “depression risk by type” keep circulating on social media and forums. Some rank all 16 types; others give each type a reason it “breaks down easily.” If your mood has been low lately, or someone close to you seems to be struggling, it is natural to look for an answer in a type. But these lists rarely say who was studied, or how.

The short answer: the MBTI does not measure depression, and it does not measure neuroticism, the personality trait most closely tied to depression. We found no research-based ranking of the 16 types by depression. A few studies that gave the MBTI to people with depression found that more of them came out on the Introversion (I) and Sensing (S) sides, but the samples were small, and every one tested people who were in treatment for depression. Any type can become depressed, and any type can get better.

If your mood has stayed low, the past two weeks will tell you more than your type. The depression check-in (PHQ-9) walks you through those two weeks, and depression symptoms covers which signs to watch for. This guide then looks at the studies that put the MBTI and depression side by side, what the Big Five personality traits add, and how to read a type ranking with a critical eye.

The MBTI describes what feels natural to you through four preferences. On each of four axes, Extraversion-Introversion (E–I), Sensing-Intuition (S–N), Thinking-Feeling (T–F) and Judging-Perceiving (J–P), you lean one way or the other, and the four leanings together name one of 16 types. There are no right or wrong answers, and neither side of an axis is the healthier one.

Depression is not a preference; it is a health problem. The World Health Organization (WHO) describes it as a depressed mood or a loss of pleasure or interest that lasts most of the day, nearly every day, for at least two weeks, together with other symptoms such as poor concentration, excessive guilt, hopelessness about the future, changes in sleep and appetite, or feeling very tired. The WHO also states that there is effective treatment for mild, moderate and severe depression (WHO, 2026). A diagnosis is made by a professional, in an interview.

One is a questionnaire about how you like to do things; the other is about your health right now. So an MBTI result cannot tell you whether you have depression. Whether the two are related at all can only be checked by giving the MBTI to people with depression, or by following personality and depressive symptoms together over time.

The first study comes from a team at the University of North Carolina. It gave the MBTI to 130 patients with unipolar depression (depression without episodes of mania) and compared them with general norms. The patients came out more often than the norms on the Introversion (I), Sensing (S), Feeling (F) and Perceiving (P) sides, and among four-letter types, ISFP and INFP were more common (Janowsky et al., 2002, from the abstract). In the same team’s study of social anxiety, 24 inpatients with major depressive disorder, included for comparison, also scored on the Introverted side (Janowsky et al., 2000, from the abstract). We could not read the full text of either study, so we give no percentages by type. These findings show which types were common among patients with depression; they do not mean that people of those types are more likely to become depressed, for reasons explained below.

A team in Uruguay gave the Spanish edition of the MBTI to 82 patients with depression who had come to a university-run community counseling center or a medical center. When the 71 who scored 9 or more on the Beck Depression Inventory (BDI) were compared with the norm data, 72% of them came out as Introverted (I), against 46% in the norms, and 78% as Sensing (S), against 56%. Thinking-Feeling and Judging-Perceiving showed no meaningful difference. Among four-letter types, ISTJ was the most common in both the norms (11%) and the patients (24%), and ISTP was 3% of the norms and 14% of the patients, a statistically significant gap. These are shares of patients, not the chance that people of a type become depressed. Split by severity, 79% of the patients scoring 19 or more on the BDI came out as Introverted (I), against 56% of those scoring lower (Amezaga & Saiz, 2015). Although both studies recruited patients with depression, the four-letter types that stood out were not the same as in the North Carolina study, and the authors wrote that their sample of 71 and the way it was recruited do not allow the results to be generalized.

These patient studies share some limits. First, all of them tested people who were in treatment for depression. Depression drains interest and energy, which can change how people answer, and as shown below, research has found that depressive symptoms can shift personality scores. Second, they compared patients with norm data drawn from other people, not with a control group matched for age and sex. Third, the patient samples were small, from 24 to 130 people. Fourth, finding a type more often among patients is not the same as people of that type being more likely to become depressed. The 14% in the Uruguayan study is the share of patients who came out as that type; it says nothing about what share of people with that type become depressed. Answering that would mean giving people the MBTI before they become ill and following them for years, and we found no study that did so.

Korean studies point in different directions. One analyzed 481 university students who had come to counseling centers and scored high on at least one scale of the Minnesota Multiphasic Personality Inventory (MMPI); Introversion (I) was related to the MMPI depression scale (Lim et al., 2008, from the abstract). A 2024 study of nursing students, on the other hand, found that levels of depression did not differ meaningfully by MBTI type (Cho, 2024, from the abstract). In November 2026 we also searched the Korean database RISS and the medical database PubMed and found no journal article that compared depression rates across the 16 types and ranked them.

Since few studies link the MBTI and depression directly, the Big Five, the model most widely used in research, can serve as a bridge. McCrae and Costa reported that the four MBTI scales capture parts of four of the five Big Five dimensions (McCrae & Costa, 1989). When 900 people took both tests, the same pairs appeared: Extraversion-Introversion lined up with extraversion, Sensing-Intuition with openness, Thinking-Feeling with agreeableness and Judging-Perceiving with conscientiousness (Furnham et al., 2003). That leaves neuroticism, the tendency to feel negative emotions such as worry and sadness easily, with no MBTI scale at all. The mind.io Big Five test calls this trait Emotional sensitivity.

Personality and depression have been studied far more. A 2010 meta-analysis of 175 studies of adults looked at the personality of groups diagnosed with depressive, anxiety and substance use disorders. Every diagnostic group was high on neuroticism (mean d = 1.65) and low on conscientiousness (mean d = −1.01). Many diagnoses also went with low extraversion, most of all dysthymic disorder, a long-lasting chronic depression (d = −1.47). Agreeableness and openness were largely unrelated, and the differences were larger in patient samples than in samples from the general population (Kotov et al., 2010, from the abstract). Here, d is how many standard deviations apart two groups’ averages are.

Studies that followed the general population rather than patients found much smaller links. A 2015 analysis pooled 10 cohorts from the US, the UK, Germany and Australia, 117,899 people in all. Put personality scores and depressive-symptom scores on the same scale (standard deviations), and the standardized regression coefficient (B) says how many steps the symptom score moves when a trait score is one step higher. In data measured at a single point in time from more than 115,000 people, B was 0.39 for neuroticism, −0.08 for extraversion and −0.09 for conscientiousness. The extraversion and conscientiousness figures hold neuroticism constant. In the 56,735 people looked at again about 5 years later, with earlier symptoms taken into account, the figures shrank to 0.12, −0.03 and −0.04 (Hakulinen et al., 2015). The authors said the reasons these links came out smaller than in earlier meta-analyses are not known, but that publication bias and their adjustment for neuroticism may have played a part.

Carried across the bridge into MBTI letters, the picture looks like this. It is our translation, not something the studies measured. Low extraversion lines up with Introversion (I) and low conscientiousness with Perceiving (P), so depressive symptoms may be linked a little to the I side and a little to the P side. In the population study, the two coefficients were similar, too: −0.08 and −0.09. Openness and agreeableness were largely unrelated to depression, so through this bridge, Sensing-Intuition and Thinking-Feeling are not linked to it. That means the bridge does not explain why the patient studies found more Sensing (S) or Feeling (F). And neuroticism, the trait most strongly tied to depression, had a coefficient (0.39) more than four times those for extraversion and conscientiousness, yet it is in none of the four letters.

The link runs both ways. In the same 2015 analysis, depressive symptoms in turn changed personality scores years later: people with depressive symptoms tended to become higher in neuroticism and lower in extraversion, agreeableness and conscientiousness, changes the authors said may be temporary or lasting (Hakulinen et al., 2015). Carried across the bridge, this means an MBTI taken during a low period may lean toward Introversion (I), Perceiving (P) or, with lower agreeableness, Thinking (T). The Uruguayan finding that patients with heavier symptoms were more often Introverted can be read the same way. Whichever comes first, links this small cannot tell you how any one person is feeling from their letters.

First, most rankings give no source. It is hard to find one that says how many people took which test, or how depression was judged. Even the patient studies above did not rank the 16 types; they compared the preferences that were common among patients with the norms.

Second, a type is not neuroticism. The trait most strongly tied to depression is in none of the four letters, so people who share a type can differ widely in Emotional sensitivity. How sensitivity relates to the MBTI is covered in our guide to sensitivity and MBTI types.

Third, an average does not describe a person. In the population study, the coefficients for extraversion and conscientiousness were −0.08 and −0.09. That only means group averages differ a little: the depressive-symptom scores of people higher and lower in extraversion or conscientiousness mostly overlap. Carried across our bridge, the same would hold for the Introverted and Extraverted sides, and for the Judging and Perceiving sides. On top of that, the MBTI measures four fairly independent dimensions rather than truly distinct types (McCrae & Costa, 1989), so an axis near 50:50 can change letter when you retest. Our guide to MBTI accuracy explains why.

Fourth, a result from a hard stretch may not reflect your usual self. As shown above, depressive symptoms can shift personality scores, so an I or a P you got while worn out may be an answer from that period. Before deciding that a ranking proves “it’s just my type,” think back to when you took the test.

Fifth, type descriptions fit almost everyone a little. A line like “seems fine on the outside but keeps a lot bottled up” sounds right to nearly anyone. The tendency to accept descriptions that would fit almost anyone is called the Barnum effect. If a ranking’s description of a “fragile type” feels spot on, that may have little to do with your type.

Sixth, labels can cut both ways. Taking “I’m an I, so I’m just the gloomy kind” to heart can make a state that can improve feel like fate. Believing “cheerful E types never get depressed” can make it easy for an outgoing person, and the people around them, to miss the signs. Depression can come to anyone, whatever their type, and it can get better with treatment.

mind.io has no “MBTI depression test,” because there is no evidence that a type can pick out depression. If you want to know how you are doing, a check-in that asks about your state directly is more useful than your type.

The depression check-in (PHQ-9) has 9 questions and takes about 2 minutes. It is a screening tool that looks back at how often you have had symptoms of depression over the past two weeks. It is not a diagnosis; it shows whether a closer look may help, and mind.io suggests talking with a professional at a score of 10 or more. The result is saved only in this browser, and the check-in has no share link.

If you are curious about neuroticism, the trait the MBTI leaves out, look at the Emotional sensitivity score in the Big Five test (30 statements, about 6 minutes). Each of the five traits is scored from 0 to 100, and the result page explains that a higher Emotional sensitivity score means you tend to feel emotions such as stress, worry and sadness more strongly and more often. It is not a good or bad score, and a high one does not mean you have depression. The page also suggests talking to someone you trust or a professional if those feelings keep disrupting daily life.

The MBTI test (32 statements, about 4 minutes) shows how far you lean on each of the four axes, in percent; it does not measure your mood. If you took it during a very hard stretch, try it again once you feel better and compare.

All the check-ins and tests in this guide are tools for self-reflection, not diagnoses. The mind.io MBTI test is not the official MBTI (Myers-Briggs Type Indicator); it is a free MBTI-style test built around the same four preference axes. The Big Five test is a self-report questionnaire built from mind.io’s own statements.

Please do not read someone’s mood from their type. Remarks like “you’re an I, so you’re always a bit down” or “you’re an E, you’ll be fine” get in the way of asking how they are actually doing, and listening. If you are worried about someone, skip the type and ask how they have been sleeping, or whether the things they used to enjoy still feel good.

If low mood or loss of interest has lasted more than two weeks, or it is getting in the way of work, school, home life or relationships, talk with a doctor or a mental health professional, whatever your type. Depression can get better with treatment.

If you ever have thoughts of harming yourself, please do not carry them alone: in the US and Canada call or text 988, in the UK and Ireland call Samaritans on 116 123, or contact your local emergency number.
