Which MBTI is the hardest to understand?

The Myers-Briggs Type Indicator (MBTI) is a popular personality assessment that categorizes individuals into 16 distinct personality types. Despite its widespread use, some MBTI types are often considered more complex and difficult to grasp than others.

What is MBTI?

The MBTI categorizes individuals based on four dichotomies that represent two opposite preferences or tendencies:

  • Extraversion (E) vs Introversion (I)
  • Sensing (S) vs Intuition (N)
  • Thinking (T) vs Feeling (F)
  • Judging (J) vs Perceiving (P)

This results in 16 possible personality types like ESTJ, INFP, ENTP, and so on. Each type has its own unique strengths, weaknesses, and tendencies.

Why are some MBTI types harder to understand?

There are a few key reasons why certain MBTI personality types may be more enigmatic and complex:

  • Rarity – Some types, like INFJ and INTJ, are quite rare in the general population. This means people have less exposure to these types and their thought processes.
  • Isolation – Types that lead with introversion, like INTP and ISFJ, may be more inwardly focused and private, making it harder for others to get to know them.
  • Abstract reasoning – Intuitive types like ENTP and ENFP thrive on abstract ideas and possibilities, which is less tangible than sensory information.
  • Individualistic – The most independent types, like INTP and ISTP, have such idiosyncratic ways of thinking that they defy stereotypes.

Additionally, some MBTI types use cognitive functions that are quite different from how most people process information and make decisions.

The 5 Most Difficult MBTI Types to Understand

Based on their rarity and unique qualities, here are 5 MBTI personality types that tend to be the most perplexing and hardest to comprehend fully:


INFJs are the rarest MBTI type, making up only 1-3% of the population. Nicknamed “The Counselor,” INFJs have a unique ability to intuitively understand people and empathize. However, they are very private, with an inner world that is complex and difficult to penetrate.


INTJs are analytical, strategic thinkers who love logic and complex problem solving. But as introverts, they reveal little of themselves and their intense thought processes to the outside world. Their brilliance and single-minded determination make them a puzzle to many.


These logical, abstract thinkers thrive on theorizing and intellectual discovery. INTPs have little interest in the everyday world and practical affairs, preferring to spend time unpacking ideas and concepts. Their intense inward focus and detached nature makes them hard to get to know.


ISTPs are adventure-seekers who are reactive and tuned into their physical surroundings. They live very independently, following their own path and analyzing the world through their own internal logical framework. Few people understand their unconventional ways and enigmatic nature.


ENFPs are enthusiastic, creative, and people-focused. Their strong intuition and imagination lead them in novel directions which are sometimes difficult for others to comprehend. ENFPs think abstractly and divergently, making them intellectually complex.

Why is the INFJ the Most Mysterious MBTI Type?

The INFJ is considered the hardest MBTI type to understand. Here’s why the INFJ is often seen as the most mysterious personality type:

  • Very rare – INFJs are the rarest personality type.
  • Private and complex inner world – INFJs are very internal and guarded about sharing their inner selves.
  • Think and process information differently – INFJs rely heavily on intuition over sensation and have a future-oriented perspective.
  • Idealistic visionaries – INFJs are guided by their personal values and principles, envisioning a better future.
  • Empathic counselors – INFJs have great insight into others but few understand them in return.

In summary, INFJs are complex paradoxes – simultaneously creative yet analytical, compassionate yet resolute, thoughtful yet decisive. The combination of their rareness and their many contradictions culminates in an extremely enigmatic personality that most find difficult to unravel and truly get to know.

What are the Biggest Misconceptions About Complex MBTI Types?

When it comes to the most complicated MBTI personality types like INFJ and INTJ, there are some common misconceptions:

They are cold and robotic

While they may seem aloof and overly analytical at times, complex types like INTJ have deeply held values and care a great deal about things they are passionate about. They just don’t show emotions as openly.

They are antisocial loners

These types simply need time alone to recharge and process their thoughts. But they often enjoy meaningful conversation and relationships once they are comfortable with someone.

They are arrogant know-it-alls

Their insightful minds can come across as egotistical sometimes. In truth, they are very self-critical and always striving to improve their knowledge.

They are hopeless romantics

While imaginative types like INFJ do have romantic tendencies, they are very thoughtful in relationships. Their idealism is balanced by pragmatic concerns when it comes to love.

How to Interact With the Most Complex MBTI Types

If you want to better understand or communicate with the most hard-to-grasp MBTI personalities like INTJ or INFJ, here are some tips:

  • Ask probing questions to understand their thought processes and values.
  • Don’t pry into their inner world too quickly; build trust over time.
  • Appeal to their intellectual side with complex ideas.
  • Discuss abstract concepts and future possibilities they may find interesting.
  • If they open up, don’t take advantage of their vulnerability.
  • Give them time and space to process information.
  • Show you care about understanding them more deeply.

In Conclusion…

Personality types like INFJ, INTJ, and INTP are among the most difficult MBTI types to truly comprehend. Their complex thought processes, insightful intelligence, and reserved natures makes them a unique challenge to get to know on a deeper level. But by understanding their motivations and respecting their need for space, you can gradually gain their trust and appreciation. At the end of the day, the “hardest” MBTI types often turn out to have some of the most rewarding interiors once you are privileged with access to their inner worlds.
