Have you ever taken a personality test and been surprised by the result? Many people enjoy learning about their personality type and comparing it with others.
Personality types can show how we think, decide, connect with others, and handle daily life.
One of the most well-known systems is the Myers-Briggs Type Indicator (MBTI), which sorts people into 16 personality types based on their preferences and behaviors.
Some MBTI types are much less common than others, which often leads people to ask which one is the rarest.
INFJ has long been called the rarest personality type, but newer data has raised questions about its rank.
In this blog, you’ll learn about all 16 personality types, how they compare in rarity, and whether INFJ still holds the title of the rarest MBTI type.
Quick Answer: What Is the Rarest Personality Type?
The INFJ is often considered the rarest personality type in the Myers-Briggs Type Indicator (MBTI) system.
Based on U.S. population data, INFJ is widely cited as the rarest MBTI type, representing roughly 1.5% of the population.
However, the 2018 MBTI Manual, sourced from 16,773 people across 23 countries, shows ENTJ at 1.8% as the rarest globally, with INFJ now at approximately 2.3%. The difference comes down to which sample you use.
What stays consistent: all four of the rarest types (INFJ, ENTJ, INTJ, ENFJ) share the Intuition (N) preference, which only about 27% of people have.
Rarity rankings shift depending on the population studied, but Intuitive types consistently cluster at the rare end.

What Is the Myers-Briggs Personality Test?
The Myers-Briggs Personality Test, often called the MBTI, is one of the most widely used personality assessments in the world.
It was created by Katharine Briggs and Isabel Briggs Myers, based on Carl Jung’s personality theories.
The goal of the test is to help people better understand how they think, communicate, and make decisions.
The MBTI evaluates preferences across four categories: Introversion or Extraversion, Sensing or Intuition, Thinking or Feeling, and Judging or Perceiving.
Based on these preferences, each person is assigned one of 16 personality types.
Many people use MBTI for personal growth, career planning, relationships, and understanding their strengths.
The Four MBTI Preference Pairs
The MBTI identifies personality types using four preference pairs. Each pair represents different ways people gain energy, process information, make decisions, and organize their lives.
- Introversion (I) vs Extraversion (E): Introverts recharge through quiet time and reflection, while extraverts gain energy by interacting with people and activities.
- Sensing (S) vs Intuition (N): Sensing types focus on facts and details, while intuitive types look for patterns, ideas, and possibilities.
- Thinking (T) vs Feeling (F): Thinking types rely on logic and analysis, while feeling types prioritize values, emotions, and relationships.
- Judging (J) vs Perceiving (P): Judging types prefer planning and structure, while perceiving types enjoy flexibility, spontaneity, and open options.

In recent years, some reports have suggested that types such as ENTJ or INTJ may rival INFJs in rarity depending on the sample studied.
Even so, INFJs continue to be widely recognized as one of the least common and most distinctive MBTI personality types.

Rarest MBTI Type by Gender
Rarity looks different when you break it down by gender. The Thinking/Feeling split is the most heavily gendered dimension in the MBTI: about 68.6% of men prefer Thinking compared to just 38.8% of women.
Rarest MBTI Types Among Men
Among men, the rarest types are Feeling-dominant, because the majority of men lean toward Thinking. INFJ is the rarest male type, estimated at around 1.3% to 1.5% of the male population.
ENFJ is similarly rare among men, at roughly 1.6%.
Men who test as INFJ often describe a sense of being out of step with cultural expectations, their natural preference for empathy and interpersonal depth runs counter to the Thinking-dominant majority of men around them.
Rarest MBTI Types Among Women
Among women, the rarest types are on the Thinking side. INTJ and ENTJ women are each estimated at roughly 0.9% of the female population, making them among the rarest gender-specific personality profiles in any MBTI data source.
Female INTJs and ENTJs often bring strong decision-making and strategic thinking into many spaces.
Since these traits are less common among women, they may face friction in social or work settings that expect more Feeling-based communication.
Why Are Some MBTI Types so Rare?
Some MBTI personality types are less common because personality develops through a mix of genetics, life experiences, culture, and how traits are spread across society.
- Genetics and Personality: Genetics can influence traits like introversion, intuition, and thinking patterns, making some personality combinations naturally less common.
- Environment and Upbringing: Family, education, and life experiences shape personality development, encouraging certain traits while making others less likely.
- Cultural Influences: Different cultures value specific behaviors and traits, which can affect how often certain personality types appear.
- Personality Distribution in Society: Some personality traits are naturally more common than others, leading to a higher number of certain MBTI types.
Conclusion
The rarest MBTI personality types often include INFJ, INTJ, ENTJ, and ENFJ, though rankings can vary slightly between studies and populations.
For many years, INFJ has been widely recognized as the rarest personality type, especially among men.
However, newer personality data suggests that INFJ may no longer hold the top spot in every survey, as type distributions continue to shift over time.
