What is the Rarest Personality Type? Traits that Make Rare Personality Types Stand Out

We all want to feel unique, like there’s something special that sets us apart from the crowd. That’s part of the appeal of personality tests like the MBTI. They give us a deeper understanding of who we are, while also hinting at how rare or common our type might be. 

When I first found out my MBTI type, one of the first things I wondered was: How rare is this? It’s a natural question. There’s something captivating about knowing whether you're one of the few who see the world a certain way.

Some MBTI types are far less common than others, and while the exact rankings can vary depending on the population studied, certain types consistently rank at the bottom in terms of frequency.

To answer this question, we’ve examined multiple sources — including large-scale surveys and scholarly research — to identify which MBTI personality types are genuinely the rarest. The results might surprise you, especially if you’ve ever felt a little different from those around you. 

What is the Rarest MBTI Personality Type?

Overall, the rarest MBTI personality type word is the INFJ. INFJ stands for Introversion, Intuition, Feeling, and Judging. Also known as The Advocate or The Counselor, this personality type is found in only 1.5% of the overall population, making it the rarest personality type. It is also the rarest among the male population.

INFJ personalities are characterized by their great sense of humanitarianism and their natural intuition. They are good at understanding the motivations and emotions of other people and work hard to help people around them achieve their dreams.

Combinations involving Intuition (N) and Judging (J) are among the least common.

The four NJ types – INFJ (1.5%), ENTJ (1.8%), INTJ (2.1%), and ENFJ (2.5%) – together constitute only 7.9% of the population. This rarity suggests that individuals who primarily orient themselves through future possibilities, strategic planning, and systemic thinking (hallmarks of NJ preferences) are statistically uncommon.

Why is INFJ the Rarest?

The rarity is shaped by both biological predisposition and cultural dynamics. 

From a psychological standpoint, INFJs possess a unique blend of preferences — Introversion, Intuition, Feeling, and Judging — that naturally occurs less frequently in the population. Their dominant function, Introverted Intuition (Ni), is especially rare and centers on future-focused, abstract thinking that often diverges from the more common, detail-oriented Sensing perspective.

Estimated Frequency of MBTI Types in the World

Note: These percentages are based on aggregated U.S. population samples (primarily data collected 1972-2002 by CAPT, CPP, Inc., and SRI, as reported in the MBTI Manual and related scholarly sources).  

Notable Gender Differences in MBTI Type Prevalence

Some MBTI types appear more often in one gender than the other. These patterns may reflect both biological tendencies and cultural influences, showing how personality traits are shaped — and sometimes limited — by societal expectations. 

The table below shows the percentage of each of the 16 MBTI personality types by gender. To highlight key trends, the types are grouped by Feeling and Thinking preferences, and a final column shows the difference in representation between women and men.

Before we move on to the rarest personality types by gender, it’s worth noting a striking pattern in a few of the more common types. 

ESFJ and ISFJ are among the most prevalent types in women, yet show up far less often in men. Conversely, ISTJ is one of the most common types for men, but is significantly less represented among women. These types aren’t rare in the population as a whole, but within a specific gender, they almost function as the mirror image of rarity.

The Rarest Personality Type for Men

As stated above, INFJ is the rarest personality type among men, making up only about 1.3% of the male population (compared to 1.6% of women). INFJs are known for being gentle, idealistic, emotionally attuned, and deeply introspective.  

Some experts suggest that INFJ men are rare because this type reflects traits that are more culturally associated with femininity, such as empathy, sensitivity, and emotional intelligence. These characteristics align with the MBTI’s “Feeling” function, which is statistically less common in men.

In contrast, Thinking-dominant types — like INTJ or ISTJ — are more prevalent among men. This doesn’t mean men can’t be compassionate or emotionally aware. Rather, it reflects broader personality trends and the influence of cultural norms, which may shape how men respond to personality assessments and how they develop emotional traits over time. 

The Rarest Personality Type for Women

According to MBTI data, INTJ and ENTJ are tied as the rarest personality types among women, with only 0.9% of the female population represented in each. Compare that to men, where these types occur more frequently — 3.3% of men are INTJs, and 2.7% are ENTJs. That’s more than triple the rate for INTJs and three times higher for ENTJs.

INTJ and ENTJ women both stand out for being strategic, analytical, and independent thinkers — traits that are often culturally associated with masculinity. While they share a Thinking-dominant, goal-driven approach, they differ in how they operate socially: ENTJ women are typically more outspoken and assertive in group settings, while INTJ women tend to prefer working independently and behind the scenes.

These personality types are statistically rare among women, in part because the Thinking trait is less common in the female population overall. Social and cultural expectations may also play a role, as women are often encouraged to develop more Feeling-oriented traits, like empathy and harmony, rather than logic and assertiveness. This contributes to the significant gender gap seen in types like ENTJ and INTJ.

This doesn’t mean women can’t have or express the Thinking trait. It just highlights broader population trends. What matters most is recognizing which trait — Thinking or Feeling — best serves the situation and using that strength with intention. 

To understand these patterns more clearly, it helps to look beyond full types and explore the four core personality dimensions.

Prevalence of Individual MBTI Preference Dichotomies 

Beyond the frequencies of the 16 full types, examining the distribution of preferences within each of the four dichotomies provides further understanding of population-level psychological landscapes.   

When we look at how people differ in their personality preferences, the biggest gap appears in how they take in information, specifically, between Sensing and Intuition. Around 73% of people prefer Sensing, while only 27% prefer Intuition. That’s a difference of nearly 47%, which is much larger than the differences seen in other traits like Extraversion vs. Introversion or Thinking vs. Feeling. 

This means that how we gather and process information is one of the most significant ways people differ. It also explains why people with different preferences — especially Sensors and Intuitives — may see the world in very different ways or struggle to communicate clearly with each other.

While overall dichotomy preferences provide helpful insights, some gender-based trends also stand out — particularly in the Thinking vs. Feeling dimension. Roughly 75% of women prefer Feeling, while about 65% of men prefer Thinking. Other dichotomies, like Extraversion vs. Introversion and Judging vs. Perceiving, are more evenly split between men and women.

Understanding the Rarest Personality Types

From the list above, we can conclude that among the 16 MBTI types, the rarest personality types have some things in common. They’re Intuitives and Judgers.

However, it’s important to mention that being rare doesn’t make you superior or more desirable.

Every personality type is special, with its own strengths and weaknesses, and every individual is unique despite their personality type. The Myers-Briggs and other personality classifications help you get insights into the strengths and weaknesses of different personalities so you can see where to improve to become a well-rounded human being.

So, embrace your traits and celebrate what makes you special rather than worrying whether you have the rarest type or the most common personality type. After all, it’s not just those with a rare personality type that often feel misunderstood, but also those with a common.

You can improve your personality by developing good communication skills, being comfortable with who you are, acquiring new skills and knowledge, and prioritizing accountability.
