10 Reasons Why INTJs and INFJs Make Great Friends

What’s your best friend like? Are they INTJs or INFJs like you?

INTJs and INFJs feel most comfortable when plans are made and stuck to, as opposed to acting in the spur of the moment.

How much are they like you? Or are they completely different?

There is no true formula to friendship… or is there?

Compatibility can lead to the strongest friendships, and no personality types are more compatible than INTJs and INFJs.

What is an INTJ Personality Type?


Myers-Briggs theory is an adaptation of the theory of psychological types produced by Carl Gustav Jung. It is based on 16 personality types […]. At the heart of Myers-Briggs theory are four preferences. Do you prefer to deal with:

  • People and things (Extraversion or “E”), or ideas and information (Introversion or “I”).
  • Facts and reality (Sensing or “S”), or possibilities and potential (Intuition or “N”).
  • Logic and truth (Thinking or “T”), or values and relationships (Feeling or “F”).
  • A lifestyle that is well-structured (Judgment or “J”), or one that goes with the flow (Perception or “P”).

The personality type INTJ is an acronym for introverted (I), intuitive (N), thinking (T), and judging (J).

INTJ indicates a person who is energized by time alone (Introverted), who focuses on ideas and concepts rather than facts and details (iNtuitive), who makes decisions based on logic and reason (Thinking) and who prefers to be planned and organized rather than spontaneous and flexible (Judging).

INTJ is the 3rd rarest personality type and is found only in 2% of the general population (3% of men and 1% of women).

Famous faces who can be categorised as INTJ personality types include Bill Gates, Stephen Hawking, Lewis Carroll, and Sir Isaac Newton.

What is an INFJ Personality Type?

Much like INTJ, INFJ is an acronym for Introverted (I), Intuition (N), Feeling (F), and Judging (J).

Each of the four letters of the INFJ code signifies a key personality trait of this type. INFJs are energized by time alone (Introverted), focus on ideas and concepts rather than facts and details (iNtuitive), make decisions based on feelings and values (Feeling) and prefer to be planned and organized rather than spontaneous and flexible (Judging).

Only 2% of the general population (2% of women and 1% of men) have this personality type, making it the rarest in the world.

Famous people who possess a INFJ personality type include Adam Sandler, Eleanor Roosevelt, Oprah Winfrey, and Nelson Mandela.


INFJs and INTJs are suited to each other in many ways.

Friendship and compatibility can be difficult concepts to discover and nurture. However, for the personality types INTJ and INFJ, common ground is easy to establish.

Here are 10 reasons why INTJs and INFJs make the best of friends…



Both INTJ and INFJ personality types are sceptical by nature. Whether that scepticism be pointed toward religion, social tradition, or anything in between, INTJs and INFJs are not afraid to question the world around them.

Which leads us perfectly into the next point…

A Thirst for Knowledge

This falls under the initiative (N) branch of their personality types.

Neither an INTJ nor an INFJ are likely to take things at face value. Instead, INTJs and INFJs are analytically minded and take pleasure in exploring concepts, ideas, asking questions, and sharing the knowledge they have acquired.

All in all, both INTJs and INFJs are traditionally high achieving personality types (whether that be academically or professionally).


A somewhat unsurprising fact consider ‘introvert’ is also present in both acronyms – introversion is a huge part of an INTJs and an INFJs life.

Both personality types tend to draw themselves inward to explore thoughts, feelings, and ideas (as opposed to a more extroverted personality type).

INTJs are commonly more private with their feeling when compared to their INFJ counterparts.


As discussed above, both INTJs and INFJs are the judging type – however not in the traditional sense…

The term ‘Judging’ is in reference too decision making – not perception.

This means the INTJ and INFJ personality types prefer structure as opposed to spontaneity. For example, INTJs and INFJs feel most comfortable when plans are made and stuck to, as opposed to acting in the spur of the moment.

Similar Values & Goals


Both INTJs and INFJs share similar values and goals.

Whether it be looking for love or achieving academic / work goals, INTJs and INFJs will understand and support their friends desire for success because they too share that trait.

Additional values held by both INTJs and INFS include truth-telling, loyalty and commitment.


Both the INTJ and INFJ personality types are (traditionally) fiercely independent people.

Neither go out of their way to form relationships and are usually content with exploring their individual interests.

If you are like this and are either an INFJ or an INFJ personality type, we have the solution for you… An INTJ / INFJ friendship.

Why? Because sharing similar interests can bond those who previously felt the need to peruse interests independently whilst eliminating the pressure of neediness/disinterest from the second party.


Another common trait of the INTJ and INFJ personality types is stress.

Both get stressed out by similar incidents and situations (for example conflict with others or an unplanned change of routine).

In addition to this both handle stress in similar ways, meaning they can understand and comfort each other when times get hard (after all, that’s what friends are for).

Sense of Humour

Being able to laugh with each other is an important part of friendship.

Both INTJs and INFJs share a dark and sarcastic sense of humour.

Their use of sarcasm serves their personality type on many levels – dark humour and sarcasm is often very smart (knowledge) with an underlying message (truth).

Easy Conversation


Both INTJs and INFJs possess a trait called Introverted Intuition;

Intuitive people process data through impressions, possibilities and meanings, so the Introverted Intuition function allows a person to have a sense about the future. Introverted Intuition is the ability to grasp and get a sense of a pattern or plan.

INTJs and INFJs being ‘Intuitive People’ often lead to deep conversations concerning ideas, concepts, and experiences.

Appreciating Each Other’s Differences

INTJs and INFJs do in fact differ in many ways. For example,

  • Differences in the decision-making process.
  • They are perceived differently by others – whether that be too cold (INTJs) or too sensitive (INFJs).
  • INTJs are more reserved whereas INFJs are more open with their feelings.

And more.

However, their differences complement each other.

INTJs often motivate INFJs with their strategic decision making and INFJs help INTJs access their emotional side…

Final Thoughts.

So, if your personality type is INTJ, consider a friendship with an INFJ personality type – your personalities will bring out the best in one another and, who knows, you may even become great friends.
