ISFJ is the most common at about 13.8%, followed by ESFJ and ISTJ. The rarest types are all introverted intuitives, and the most common types are all sensing types, because Sensing is preferred by about three out of four people.

These are the widely cited estimates compiled by the Center for Applications of Psychological Type and published in the MBTI Manual. They are based on US samples, so treat them as a rough picture rather than exact counts.

Why INFJ is the rarest personality type
INFJ sits at the bottom of the distribution because it stacks three minority preferences. Intuition (N) is already a minority trait, since most people prefer Sensing. Combine Intuition with Introversion and a Feeling-Judging structure and you get a profile that simply does not show up often.
There is also a perception effect. INFJs tend to be private and selective about who they open up to, so they rarely cluster in visible groups. That makes the type feel even rarer than 1.5%, because an INFJ can go years without knowingly meeting another one.
The most common personality type
At the other end, ISFJ tops the list at about 13.8%. ISFJ pairs Sensing with a caretaking, detail-oriented, duty-driven style, and those traits are both common and socially rewarded. The four most common types, ISFJ, ESFJ, ISTJ, and ISFP, are all Sensing types, and together they account for a large share of the population.
The single biggest split in the whole system is Sensing versus Intuition. Roughly three out of four people prefer Sensing, which is why every one of the rarest types is intuitive and every one of the most common types is sensing.
Rarest four versus most common four
| Rank | Rarest types | Most common types |
|---|---|---|
| 1 | INFJ, 1.5% | ISFJ, 13.8% |
| 2 | ENTJ, 1.8% | ESFJ, 12.3% |
| 3 | INTJ, 2.1% | ISTJ, 11.6% |
| 4 | ENFJ, 2.5% | ISFP, 8.8% |
The pattern is hard to miss. Every type in the rarest column is an introverted or extraverted intuitive, and every type in the common column is a sensing type. Rarity in MBTI is mostly a story about how uncommon Intuition is.
Does a rare type make you special?
This is the part people get wrong. A rare result is not a grade. Rarity measures how often a type appears, not how capable, smart, or successful its members are. ISFJ and ESFJ are common precisely because their warmth and reliability are traits society leans on every day.
It is worth remembering that MBTI itself is a self-report framework with well-documented reliability limits. The percentages describe a population, not your potential. The healthiest way to read your type is as a language for your preferences, not a tier on a leaderboard. If you want the lighter, just-for-fun version of self-typing, What Animal Are You? and What Element Are You? give you a shareable result in a couple of minutes without any of the rarity debate.
Where the rarity numbers come from
The figures in this guide trace back to estimation samples compiled by the Center for Applications of Psychological Type and reported in the MBTI Manual. Because they come from samples rather than a full census, different sources publish slightly different numbers, and gender changes the picture too. INTJ, for example, is several times more common among men than women, which makes female INTJs one of the rarest profiles of all.
Use the percentages as a map of the landscape, not as exact coordinates. They are reliable enough to answer "which type is rarest" and "which is most common," which is exactly what most people want to know.
Frequently asked questions
What is the rarest personality type?
INFJ is the rarest Myers-Briggs personality type, estimated at about 1.5% of the population. INFJ stands for Introverted, Intuitive, Feeling, and Judging. The next rarest types are ENTJ at roughly 1.8% and INTJ at about 2.1%. All of the rarest types share the Intuitive (N) preference, which is itself a minority trait, so introverted intuitive types end up at the bottom of the distribution.
What is the most common personality type?
ISFJ is the most common Myers-Briggs personality type, estimated at about 13.8% of the population. ISFJ stands for Introverted, Sensing, Feeling, and Judging, the practical and caretaking profile. It is followed by ESFJ at around 12.3% and ISTJ at about 11.6%. The four most common types are all Sensing types, and Sensing is preferred by roughly three out of four people.
How rare is the INFJ personality type?
INFJ is estimated at about 1.5% of the general population, which means roughly 1 in 65 people. It is rarer still among men, where some samples put it closer to 1%. INFJ feels even rarer than the numbers suggest because the type tends to keep to itself, so two INFJs can go a long time without meeting another one and assume the type is more unusual than it is.
Is a rare personality type better than a common one?
No. Rarity is just how often a type appears in the population, not a ranking of worth, intelligence, or success. Every type has strengths and blind spots, and common types like ISFJ and ESFJ are common partly because their traits are socially valuable. Treating a rare result as a badge of superiority is the most common misreading of MBTI data.
Are MBTI rarity percentages accurate?
They are reasonable estimates, not exact counts. The widely cited figures come from samples compiled by the Center for Applications of Psychological Type and published in the MBTI Manual, and different studies produce slightly different numbers. MBTI itself has known reliability problems, so treat the percentages as a useful rough picture of how the 16 types are distributed, not as precise population statistics.
