What Is The Most Introverted Personality Type?

Every Myers Briggs personality type gives a title to a complex set of fundamental personality traits, each with an onion’s level of layers beneath an extroverted or introverted façade.

Introverts are a select category of Myers Briggs types, often underestimated due to their quiet demeanors.

Some people are more introverted than others, but even the most introverted MBTI can harness the strengths of their particular type to achieve great success.

We have broken down each of the introvert personality types to help you understand the difference between these types, who are likely to be the most introverted, and the strengths that lie in these quiet personalities. 

Introvert Personality Types

A Myers-Briggs introvert may not be the stereotypical loner staying in to read a book on a Saturday night.

While this is a perfectly pleasant way to spend an evening, many introverted types can actually be quite outgoing, sociable, and have many friends.

Introversion has less to do with the number of numbers saved in your phone, or how many parties you went to in college, but instead how you respond to social situations and where you receive your energy. 

Introverts get recharged from spending time alone and may find themselves drained after a big social event.

After receiving important news, an introvert would rather find a small corner of the world to be alone in order to process that information internally.

If this resonates, you may have noticed the following attributes in yourself:

  • You prefer to hang out in smaller groups.
  • You have a tight circle of friends who you know well. 
  • You're more in tune with yourself. Or you can get lost inside your head, having to retune into reality frequently. 
  • You are more deliberate in your choices, having spent time in reflection. 
  • You quickly tire when socializing. 

What Is The Most Introverted Personality Type

Everyone is unique, informed by their individual experiences, even within a single personality subset. For this reason, there is no standardized way to rank the introverted personalities.

We have ordered the following types based on an assessment of each personality’s common characteristics and ranked them from most to least introverted. 


INTP stands for Introverted, Intuitive, Thinking, and Perceiving, and this personality type is the most introverted of the Introvert Club.

An INTP lives inside their head. The space between each ear is a complex network of intuitive wiring, allowing them to be great purveyors of knowledge.

You will likely find them at home in the library, seeking out the logical mechanisms of impossible questions.

They have a fine-tuned bull crap detector and can spot when they’re being manipulated from a mile away. INTPs may seem arrogant or stuffy to some, but they rarely mean harm and are likely more critical of themselves than anyone else.

INTP’s are continually challenging their ideas, testing them against possible arguments, and reviewing their logic with a fine-tooth comb.


ISTPs are the second most introverted personality type, with the acronym standing for Introverted, Sensing, Thinking, and Perceiving. Highly intuitive and pragmatic, they are often referred to as “the Craftsman.”

They are excellent at locating the problem and testing out solutions; however, they’d like to do it on their own terms, rather than being regulated or managed.

ISTP’s great insight also gives them a comedic edge, whipping out humorous and highly perceptive wisecracks with excellent timing. They are the type to throw away the instruction manual, and build the thing themselves — likely solving several potential issues along the way.

These introverts are action-oriented, unlike other introverted personalities, not wanting to waste any time after finding a solution. 


INTJs are keen observers of patterns as they occur in the world around them and their heads. This personality type can seem to possess an almost psychic quality due to their skills of observation and insight.

The acronym stands for Introverted, Intuitive, Thinking, and Judging, meaning that people with this personality process the world through a series of potentials, opportunities, and possibilities.

They have a capacity for creativity that’s often overlooked, compared to their more expressive counterparts. Much of their creative expression, their ability to build worlds and birth characters into existence, stay inside of their heads.

The pursuit of knowledge for INTJs is a more playful one, unlike the INTP. Their mind is an experimental studio where truth and information can be toyed with and viewed from many angles.

Introverted, Intuitive, Feeling, and Perceiving — the INFP is the Introvert Club’s resident idealist, often taking on the role of a healer. The brutalities of the world are hard to bear for an INFP. Injustice and cruelty are not in their nature, nor are they easy for INFPs to deal with.

While they reflect a quiet demeanor, their minds are bursting with imagination. These are creative types, often using artistic mediums for self-expression and connection.

Their art is how they connect to humanity, as they are revealing profound truths about themselves and exposing their vulnerability to the harsh world.

They serve a role as “mediator,” devoting themselves to caring for the emotional well being of those they are loyal to. Seekers of harmony, INFPs will twist and bend themselves in knots to create balance, unless they are pushed to a breaking point. 


The Introverted, Sensing, Feeling, and Perceiving type is often referred to as “the Artist.” They possess a strong aesthetic appreciation and are attuned to sensory experiences.

Like other introverts, they gain their energy from time alone. However, they have much more of a “go with the flow” personality than an INTJ or an ISTP.

While they can be pleasant and easygoing, you may find it difficult to become close friends with this type. They often keep friendships to a minimum, possessing a small few friends they’ve likely had for many years.

Personal integrity and a strong moral compass are essential to an ISTP. They carve a unique path in the world, and they walk that path with a strong sense of right and wrong. ISTPs dislike inauthentic people or behavior and detest fakeness. They want the real thing. 


The ISFJ is a sentimental creature, a lover of beauty, and a curator of nostalgia. They are seekers of contentment and personal meaning. Everything has a significance, and even the tiniest moments are tucked away for safekeeping.

Introverted, Sensing, Feeling, and Judging — the ISFJ moves through the world in wonder. They have a unique perception of time and how it plays out in their lives. Simply put, there just isn’t enough of it.

They will be your rock in times of need and a shoulder to cry on when things get tough. ISFJs have great faith in people. They believe in the best of humanity and will guard it when they find it. They are deeply compassionate souls and have an even more in-depth understanding of their emotional worlds.

ISTJ stands for Introverted, Sensing, Thinking, and Judging. The sensory function allows for effective data collection, and ISTJs often hold a deep admiration for facts.

These personalities are detail-oriented and organized, with not a hair out of place. Once they commit themselves to a task, they will do everything they can to see it through and complete it efficiently.

They have a strong sense of loyalty to their loved ones and hold deep friendships. ISTJs often have unique interests that they are wholly dedicated to.

Spending time alone allows them to explore their curiosity and break out of their organized work life. ISTJs are observant and utilize this skill by finding patterns in the past to more effectively guess at the future. 


INFJ is the rarest Myers-Briggs personality type with only one percent of the population falling under this category. They ar the most extroverted types of our Introvert Club and one that is often dubbed as an “extroverted introvert.”

INFJ stands for Introverted, Intuitive, Feeling, and Judging. Rarely bored, INFJs have a vast network of possibilities, insights, and fascinations swirling about in their complex brains. Like INTJ’s, this personality type has almost psychic abilities, using their keen intuition and sense of feeling to guide them towards their futures.

INFJs are deeply empathic and often prioritize taking care of others. Their insights can be incredibly powerful, but they require recharging alone time for those abilities to come into fruition at their peak capacity. 

Final Thoughts

While extroverted personalities grace the covers of magazines or become the life of the party, introverts are a powerful secret force for inspiring and changing the world.

Introverts are the caretakers, knowledge-seekers, organizers, and mentors that have such a deep impact on our communities. Being an introvert doesn’t necessarily mean you're antisocial or have difficulty keeping friendships.

Introverts are the best of friends — loyal and compassionate. There is nothing more intriguing than an introvert inviting you into their beautiful, complex inner world.
