ISTJ Relationships with Other Personality Types

ISTJ Relationship Featured

ISTJs are dedicated and pragmatic individuals who like to understand how the world around them works. Extremely knowledgeable and highly logical, the ISTJ (also known as The Archivist) personality type is observant and curious. Introverts at heart, ISTJs do need time alone with their thoughts and ideas, but they also have a sentimental side that they only show to the people closest to them.

Their love for logic and practical thinking can lead others to label them as unapproachable and antisocial, but this is simply not true. While they may not be social butterflies, ISTJs cultivate relationships with people they consider important that are far from dry or cold. Therefore, in an attempt to shine a bit more light on the ISTJ universe, we will take a closer look at the ISTJ’s compatibility with other personality types and explore how ISTJs relate to their friends and loved ones.

We’ll also try to answer some of these questions:

  • What is the ISTJ partner like?
  • What is the best match for an ISTJ?
  • Which types make the best friends for ISTJs?
  • Which types have a good work dynamic with ISTJs?

ISTJ Relationships and Dating

ISTJs tend to be one of the most reliable and effective personality types, because they always make sure things are done the right way. Moreover, they take the same approach when it comes to their relationships.

Since they are huge fans of practical thinking, ISTJs don’t enjoy immersing themselves in the complexities of human interaction. In fact, they tend to find the concoction of emotions and irrationalities that comes with relationships quite annoying. As a result, they can seem cold and distant to outsiders (especially Feeling personality types).

The truth is that an ISTJ relationship needs a solid foundation and room to grow before it can bloom into something stronger. The Archivist personality type is not one to lose their head easily; they take their time and analyze the other person’s feelings and motivation for getting close. Once they deem someone worthy of their trust and love, ISTJs are willing to create a strong and long-lasting connection.

Above all, ISTJs value commitment and take their relationships seriously. That’s why they first want to be sure about their feelings and the feelings of the other people involved in their relationships.

You can read a more detailed analysis of ISTJ traits and characteristics here.

ISTJ Dating

The Archivist personality type is quite the traditionalist, and this certainly carries over to their dating life. They believe in showing their intentions with respect and seriousness at every stage of the dating process. An ISTJ falling in love will not be overly romantic or emotional, but they will do their best to show their affection in a practical and direct manner (they are honest when it comes to their feelings).

Because they take their time in both dating and love, it’s easy for others to assume that an ISTJ in love is too serious or sometimes even cold in their approach. But this is not an ISTJ’s intention- they just want to make sure the person that has sparked their interest has the right qualities to be a good partner.

Moreover, an ISTJ in relationships expects the same level of commitment and thoroughness from their partners (whether we’re talking about romantic partners or friends). Overall, the ISTJ partner is caring and protective, doesn’t like (big) surprises, and can be won over by a well-detailed schedule.

Of course, there’s more than meets the eye, which is why we’ll dig deeper into the world of The Archivist and run comparisons with each and every one of the 16 personality types.

ISTJ Best Match

The best match for ISTJ is the ESTP but they also get along quite well with ISFJs.

Why? Well, it’s all about these personality types’ dominant cognitive functions (according to the 16 personalities theory). ESTPs have the dominant function Extroverted Sensing, while the ISTJ’s dominant function is Introverted Sensing. According to the personality type concept, people are naturally attracted to people with similar dominant functions but with differently directed energy (Introverted/Extroverted). In addition, Judging personalities will naturally be attracted to Perceiving personalities, in an attempt to create a harmonious relationship.

Therefore, it makes sense why the logical and practical ISTJ could be attracted to the warm and socially adept ESTP. True, they don’t seem to have a lot in common (at first glance), but they complement each other’s wants and needs.

Some of the other best matches for ISTJ types are: INTJ, ESFJ, and ENTJ

ISTJ Relationship Compatibility

Simple and straightforward, the highly logical ISTJ sometimes seems insensitive, especially to personality types with the Feeling preference – but there’s no malice behind an ISTJ’s intentions. Their by-the-book approach to life could come across as rigid to more spontaneous personality types, but they are committed and loyal partners, friends, and coworkers. Moreover, ISTJs are quite successful at achieving their goals, even if they can be a bit stubborn in their respect for tradition.

In short, the ISTJ personality type is perhaps easy to misunderstand, on the surface. Still, they are capable of forming incredible relationships, and once they move past their inability to verbally express their feelings, many people learn to understand and appreciate them.

So no, ISTJs are not cold people; they just need more time to warm up. We’ll prove their potential by comparing ISTJ relationship compatibility with every personality type from the perspective of romance, friendship, and work.

ISTJ Compatibility Chart

Before we talk about the compatibility between the ISTJ type and all the other 16 personality types, let’s get a big-picture view of their interaction with the world (from the perspective of the 16 personality system). We put together a chart to illustrate the ISTJ’s level of compatibility with each of the other 15 personality types.

Here is the meaning behind the colors we used:

  • Blue – Natural soul mates! These types are the ones most in line with ISTJs and have the same interests and views on life.
  • Green – Not exactly perfect kindred spirits, but close enough. These people can understand the ISTJ to a point and can use their differences to build interesting and challenging relationships.
  • Yellow – They tolerate each other. The types in the yellow zone don’t quite understand where ISTJs come from, but their relationships won’t be completely rocky or full of conflict.
  • Red – These types don’t see eye-to-eye with the ISTJ. Since they are almost polar opposites of the ISTJ, it will take a lot of work to get something started (not impossible though).

ISTJ Compatibility Chart


Situated in the “blue zone” of our compatibility chart, the ISTJ and the ESTJ get along quite well.


Given that they share three main preferences (Sensing, Thinking, and Judging), it’s easy to see why ISTJs and ESTJs are so in sync. Both enjoy following rules and live in the present. In addition, both respect traditions and look for the logical solution to any difficult situation.

As romantic partners, the ESTJ may not be a “soul mate” to the ISTJ since they are so similar. However, their common interests may help them forge a logic-based and practical connection. In addition, the extroverted ESTJ is more friendly and socially open than the introverted and reserved ISTJ. This can be a good thing, since ISTJs avoid socializing for the sake of making conversation; their ESTJ partner can ease some of the load in social interactions.


Both ISTJ and ESTJ personality types are logical thinkers; they like to follow plans and achieve their goals. Therefore, as friends, they will understand each other’s way of thinking and will be ready to support each other’s efforts. Moreover, they both appreciate action over words, so communication comes easily in their friendship (in most cases).

Still, the ESTJ is direct and open about the things that dissatisfy them, while the ISTJ prefers a more reserved approach to communication. This difference can be a source of friction between the two friends, but it can also be a source of growth, depending on the situation.

At Work

ESTJs and ISTJs take their work seriously and enjoy an organized environment. They are also practical, logical, and goal-oriented, which is why they can put aside any distractions and dig into their tasks. Their main difference is the way they relate to other co-workers; the ESTJ is happier working in larger groups, while the ISTJ is more of a lone wolf who likes to work independently.


Like birds of a feather, two ISTJ personality types will get along quite nicely (which is why they are in the blue zone). Still, too much of the same thing is not always a good blend, so there will be some troubles to overcome.


As they are both logical and practical, two ISTJs dating will take their time to analyze their options before entering a serious commitment. This way, if they decide on a romantic relationship, they will pretty much have everything sorted out.

Their shared space will be organized and tidy, although they may disagree when deciding how to organize. It may also take a bit of work to find the right way to communicate their feelings to each other, since ISTJs like to let their actions do the talking.

Still, it will be easy for ISTJ partners to find shared hobbies since both enjoy activities that stimulate the senses or the body in some fashion (like cooking or arts and crafts). Therefore, two ISTJs can get closer and strengthen their bond by doing things together.


As friends, ISTJ people can have a great relationship based on mutual respect and understanding. Both introverts who are dedicated to tradition, ISTJs respect each other’s boundaries and values.

However, ISTJs trust their own experiences and sources, which is why it’s easy for ISTJ friends to get into arguments over specifics. As long as they keep an open mind and learn to accept a different point of view, however, their friendship will only become stronger with each argument.

At Work

The Archivist is an independent thinker who appreciates logical arguments and goal-oriented planning. Therefore, an ISTJ-ISTJ work relationship should flow seamlessly, right?

While they are amazing when it comes to details and identifying the most efficient solutions, ISTJs are still introverts who favor action over words. So, they may find it difficult to get their thoughts across to each other. On the other hand, they are both good listeners and can be respectful of the other’s need for space. Overall, ISTJs working together can make a great team, as long as they allow room for the other’s thoughts and opinions.


Both introverts who are focused on achieving their goals, these two personality types can develop amazing relationships together (hence, the blue on our compatibility chart). However, there are differences that, if left unaddressed, can cloud their happiness.


The relationship compatibility is quite high for an ISTJ and ISFJ, but only if the logic-oriented ISTJ learns to accept the feeling side of the ISFJ. Both these personality types value and respect traditions, and both care deeply about their commitments. Therefore, if they enter a romantic relationship, both partners will have thought it through.

But, there is a big hurdle to overcome in terms of communication. The ISFJ can seem too emotional to their ISTJ partner, who tends to be blunt in their approach. In turn, ISFJs are easily hurt by criticism and tend to take every negative remark to heart. Moreover, an ISFJ partner will often be reluctant to share anything that could lead to conflict, which may leave the ISTJ in the dark about their partner’s feelings.

Overall, a successful relationship between an ISTJ and an ISFJ is one where they both understand and accept their differences, especially when it comes to their differing Thinking/Feeling preferences.


ISTJ and ISFJ personalities are united by a love for schedules and structure, as well as a respect for tradition and commitment. Deeply practical and logical, ISTJ and ISFJ friends can easily understand each other’s view of the world.

While it takes time for a friendship to bloom since both types are reserved with new people, they are naturally attracted to each other due to common values and interests. Therefore, as long as ISTJs learn to respect ISFJs’ emotional side and ISFJs understand ISTJs are more direct by nature, this friendship can be fulfilling for both sides.

At Work

When it comes to professional relationships between ISTJs and ISFJs, efficiency and good planning are the words of the day. Both logical and pragmatic personalities, The Archivist and The Defender can successfully collaborate on a wide range of projects.

When they combine their strengths, these two types can make an invincible team. ISFJs use their heightened emotional sensitivity to understand and relate to others’ needs, while ISTJs enforce objectivity and make sure each detail of a project is well-planned. Most importantly, they can help each other grow: ISFJs can help ISTJs understand how their direct approach can influence sensitive people’s reactions, while ISTJs can teach ISFJs to be more assertive.


Due to their shared preferences (Introversion, Sensing, Thinking) there is a lot of potential for a solid connection between the ISTJ and ISTP personality types. But, even though they are blue on our chart, there is still room for misunderstandings.


Both ISTJ and ISTP personalities are fond of decisions based on logic and facts. They also value traditions, commitment, and practical solutions. In romantic relationships, both the ISTJ and the ISTP will take time to get to know their partner, but they will feel a natural attraction from the start due to their shared beliefs and values.

However, their relationship can be clouded by the fact that the ISTJ tends to find the ISTP’s spontaneity and easy-going approach to life irksome. The ISTJ personality type likes to organize their environment and thrives in structure, but this can feel limiting for the ISTP, who is happy to go with the flow and enjoys last-minute opportunities. As with any relationship, the two can either let this difference lead to conflict – or to personal growth and a broadening of their horizons.


If ISTJs can find room for their ISTP friends’ spontaneity, then a friendship is more than likely between these two personality types. However, the ISTP type must also understand and respect their ISTJ friend’s need for structure and organization.

As both types are introverts with a here-and-now approach to life, and a straightforward approach to communication, there is plenty of common ground here for a beautiful and long-lasting friendship.

At Work

In a professional environment, both ISTJ and ISTP personality types favor rational decision-making over emotional thinking. They are also organized and relentless in their pursuit of productivity and efficiency.

The main difference is that ISTPs are more comfortable with change and can adapt to unexpected events. On the other hand, ISTJs are quite inflexible and don’t feel comfortable when things don’t go according to plan. Therefore, they can follow their ISTP colleagues’ example and learn to be a bit more relaxed.


Placed in the green zone of our compatibility chart, these two personality types can develop amazing relationships, but it may take a bit of work.


In an ISTJ-INTJ relationship, the INTJ will be focused on the big picture (as expected from an Intuitive type). They like to imagine a wide range of outlandish (and sometimes unrealistic) scenarios, but their expansive vision and dreaming can be both a source of admiration and irritation for the well-grounded and present-focused ISTJ.

Still, both types are logical and prefer a straightforward and honest communication style, without bringing too much emotion to the table. Additionally, they both value organization and need structure in their lives.

In summary, as long as they learn to accept each other’s quirks and differences, an INTJ-ISTJ relationship has lots of chances for success.


The INTJ personality looks for intellectual connections before anything else, which is why they will be attracted to the highly logical and practical ISTJ. However, the ISTJ may find the INTJ a bit quirky and lost in their visions of the future, while the INTJ may view an ISTJ friend’s respect for tradition as stubbornness or being stuck in their ways.

The ISTJ is grounded in the present, while the INTJ likes to imagine the future and doesn’t care much for details. As friends, these two have a lot to learn from each other – The Archivist (ISTJ) can learn not to sweat the small details as much, while The Mastermind (INTJ) can learn to be more tuned in to present-day life.

At Work

Work relationships can be a bit challenging for ISTJ and INTJ personalities, as the Strategist’s unbridled free thinking can clash with the practical and grounded thinking of The Archivist.

Still, the ISTJ can act as a stabilizing force for the INTJ and balance out the wildness of their ideas, while still allowing the INTJ’s open-mindedness to broaden their perspective. In this situation, the ISTJ-INTJ professional team can become unstoppable. It’s a matter of proper communication and respect on both sides.


Another green match in our compatibility chart, the ISTJ and ESFJ relationship has the potential to be great.


The contrast between Introversion and Extroversion can be the spark that starts the romantic flame for ISTJs and ESFJs, but it can also serve as a source of irritation as the relationship advances.

Unlike ISTJs, empathic ESFJs are open to social engagements and relate easily to others. This may be appealing to the reserved and logical ISTJ at first, but it can get bothersome later in the relationship if they don’t learn to open up a bit more (or if their ESFJ partner doesn’t respect their need for solitude and space). On the other hand, if they assume the role of the listener and are mindful of their partner’s emotional side, ISTJs can enjoy a warm and loving relationship with ESFJ types.


The warm-hearted and supportive ESFJ may be the friend that will drag the logical ISTJ out of their shell and into some fun social events. However, for this friendship to grow and last, the ESFJ must respect an ISTJ’s need for time alone and accept their straightforward way of communicating their thoughts. On the same note, The Archivist personality type should avoid criticism and focus on being encouraging to their ESFJ friends.

At Work

Each of these two personality types has something that can help the other be more well-rounded. For instance, The Archivist is practical and focused on details and facts, which allows them to be objective in their decision making. On the other hand, The Caregiver (ESFJ) type is empathetic and social, bringing positive energy into the group. Therefore, these two can use their strengths to support each other and grow towards their professional goals.


The General (ENTJ) and the Archivist (ISTJ) share the Thinking and Judging preferences, which is why they are in the green area of our compatibility chart.


As Thinking personalities, ISTJs and ENTJs don’t have to be too careful with how they express their thoughts to one another. Still, both types can be stubborn in their arguments, which can cause intense conflicts. In addition, they both value organization and planning, but they may quarrel over the specifics of how to get things done.

ENTJs like to take the lead (a personality trait ISTJs can learn to accept) and are social and charismatic. Since ENTJs are also an Intuitive personality type, they focus on the bigger picture and tend to think about the future (another personality trait that clashes with the ISTJ’s focus on practicality and the present).

Overall, the ISTJ – ENTJ romantic relationship will take some work, but there are plenty of similarities and interesting traits that can keep them going strong.


Organized and logical thinkers, these two Thinking and Judging personalities can get along quite nicely. Their common interest in achieving their goals and their love for order, facts, and logic solidifies their friendship.

There is also plenty of room for mutual growth, as the ENTJ is the visionary, social friend while the ISTJ is the reserved, grounded friend. Together, they can learn from one another and help each other improve .

At Work

Both ENTJ and ISTJ personality types are focused on planning and achieving their goals through deep, logical thinking. However, the ENTJ is more empathetic and charismatic, so they will almost always take on the mantle of leadership. On the other hand, the ISTJ will be the detail-oriented planner who can help to ground the future-focused ESTJ.


When things go right, these two personality types can fit together like Yin and Yang, but they are in the green area because of their notable differences in personality.


ESTPs are natural partners for ISTJs because of their warm, energetic, and bold personality. Nicknamed The Persuader, these curious logical thinkers can coax the reserved ISTJ out of their shell to embark on explorations and adventures (literal or figurative).

Both are straightforward in communication style and share an interest in practical, real-world matters. These two personality types have a lot to talk about and enjoy listening to one another’s stories. Although they are both well-grounded in the present, the ESTP is more of a fun-loving, easy-going kind of person, which may frustrate the ISTJ a bit. However, once ISTJs decide to join in the fun and relax about their schedule occasionally, everything else falls into place.


These two types also get along well as friends, but one will usually be the talker (ESTP) while the other will be the listener (ISTJ). Therefore, it’s important for the ESTP to become a better listener and the ISTJ to share more about themselves for this friendship to last.

Overall, ISTJs appreciate their ESTP friends’ fun nature and respect their zest for adventure. On the same note, ESTPs respect their ISTJ friends’ commitment to goals and admire their resolve to be productive and well-organized.

At Work

While they are both practical problem-solvers and rational thinkers, in a professional environment, the ISTJ may get frustrated with their ESTP colleagues’ careless approach to planning and organization. Therefore, for a successful work relationship, ISTJs need to learn how to embrace change and unpredictability, while ESTPs need to learn how to be more structured.


The ISTJ – INTP pair is colored in yellow on our ISTJ relationship compatibility chart, which means there is potential for an amazing collaboration, but it will take some work and compromise from both parties.


Since they are both introverts who share the Thinking preference, an ISTJ – INTP couple will like to keep to themselves, using logic and analysis to find the most effective solutions to their problems.

They do have some notable differences though; the INTP personality, also known as The Logician, is more interested in exploring new and challenging ideas and less interested in making plans and following rules. This can be a point of friction in an INTP-ISTJ relationship, but it can also cultivate personal growth for both types.


Friendship may not come naturally between these two types, because they are both independent thinkers who prefer spending time on their own. Moreover, both types are frank and straightforward in expressing their thoughts, which may lead to conflict given that the ISTJ is focused on concrete details while the INTP is more of an abstract thinker.

But, if they learn to listen to each other’s point of view and try to understand it, this can lead to a beautiful friendship of the mind.

At Work

Both logical and focused on achieving their goals, these two types can bring balance to a professional environment. The INTP personality type is a free thinker who doesn’t like planning and tends to get lost in grand ideas. On the contrary, the ISTJ is happy when every detail is well-planned. They also have a strong sense of the here and now, which is helpful in balancing the INTPs future-focused vision.

Overall, it may take some work, but if ISTJ and INTP colleagues put their frustrations aside, there is room for growth.


The Sage (INFJ) and The Archivist (ISTJ) can learn to understand each other, but it may be a bit of a rough ride, which is why they are represented in yellow on our chart.


The most dominant ISTJ personality traits are their logical view of the world and their love for details. The Archivist doesn’t like mixing emotions with their rational thinking process, instead staying well-grounded through their strong observational skills. On the other hand, INFJs are altruistic, idealistic, and passionate about making the world a better place. They are also more social (despite being introverts) than the ISTJ, and they use emotions to guide their thought process.

At their best, an ISTJ and INFJ can help each other with their weaknesses and blind spots. The ISTJ can learn to be more considerate of other people’s feelings and let go of the little things from time to time, while the INFJ can learn to value logical reasoning and being more present.


As friends, an ISTJ and an INFJ can get along smoothly, as long as both of them can learn to relax their stubbornness. The INFJ is warm and caring, but they tend to get defensive about their deeply held beliefs. Therefore, the ISTJ needs to learn to accept this personality trait of the INFJ even if these beliefs don’t always make much sense to a deeply logical mind. On the same note, The Sage needs to be more accepting of The Archivist’s blunt approach and must learn to not take things too personally.

At Work

Creative, warm, and social, the INFJ brings balance to the reserved and logical ISTJ. In the workplace, these two can collaborate by using their strengths and weaknesses to balance each other out. The INFJ can help the ISTJ relate to other people’s needs, and the ISTJ can help the INFJ to be more grounded and practical.


These two types share Introversion and Sensing preferences, which means they respect each other’s need for time alone and they share good observation skills. However, the ISTJ – ISFP pairing doesn’t happen naturally, which is why they are in the yellow zone.


The ISTJ personality usually bases relationships on logic and reason, while the ISFP is more focused on emotions and is always open to new challenges. Therefore, without compromise, a relationship between these two types may get difficult since the bluntness of the ISTJ can unintentionally hurt the ISFP’s feelings. Moreover, the ISFP’s openness to new experiences and unpredictability can irritate the over-organized ISTJ.


If they learn to accept each other’s differences, these two types have a lot to learn from each other as friends. The ISTJ can learn to relate to other people’s feelings and understand how their logical approach, although correct, can be hurtful. On the same note, the ISFP can learn to be more organized and objective in their decisions.

At Work

The difference in Thinking vs Feeling preferences can affect the ISFP – ISTJ work relationship, but it can also help them bring the team together. The ISFP will appear more warm and relatable, while the ISTJ is more logical and assertive. The ISTJ’s focus on organization can also be highly appreciated in the workplace.


While the ISTJ and the ESFP are both well-grounded in the present and focused on concrete details, these two personalities don’t have much else in common – hence their spot in the yellow zone.


The ESFP is hearty and bubbly, always looking for attention and enjoying the energy they get from large crowds. Still, they can learn to admire the calm and stoicism of the ISTJ and appreciate their commitment to the relationship. In intimate relationships, the ISTJ is the sort of person who will stand by their partner through thick and thin. This can be a very appealing personality trait to the outgoing and dynamic ESFP – when the going gets tough, they know their partner has their back.

ISTJs can be attracted to the ESFP’s live-in-the-now approach, but only if it’s experienced in small doses and paired with respect for the ISTJ’s need to keep things organized. If they can loosen up, ISTJs will get to have a lot of fun with their extroverted sensing partner. On the other hand, time alone is crucial for the well-being of the ISTJ, so they will need an ESFP partner who respects their boundaries and doesn’t overwhelm them with energy and emotion.

Still, if the ISTJ doesn’t learn to accept their ESFP partner’s lack of organization and tendency to make last-minute plans, the relationship can become suffocating for the ESFP.


Reserved and introverted, the ISTJ can learn to get out of their shell and be more sociable under the influence of an ESFP friend. Still, the spontaneity and easy-going nature of the ESFP can be a source of frustration for the schedule-oriented ISTJ. Therefore, both people need to be open and accepting of their differences if they want this friendship to work.

At Work

In a professional setting, the ESFP will shine as the charming and fun colleague who everyone knows and admires. In addition, ESFPs have a natural way of bringing people together, which is in direct contrast with the ISTJ’s introverted and reserved nature. Still, if they manage to reconcile their differences, these two can take the world by a storm. In a team, the logical and goal-oriented ISTJ will appreciate the support of the highly energetic and adaptable ESFP who can help people understand the ISTJ’s point of view.


Situated in the red zone of our chart, the ISTJ and ENTP are not very similar (they only share the Thinking Preference).


Curious and communicative, ENTPs are always up for a challenge. But they also love intellectual debate, so they will be attracted to the ISTJ’s logical thinking. On the same note, the reserved ISTJ may feel attracted to the refreshing and social ENTP, but it takes more than the initial spark to put the basis of a romantic relationship between these two.

The ISTJ may be put off by the ENTP’s love for new experiences and abstract views of life. ON the other hand, the ENTP can see the ISTJ as distant and controlling (due to their need for planning and scheduling).


Besides their love for intellectual sparring, there is little common ground for these two personality types to build on in a friendship. The ISTJ’s preferences tend towards solitude and structure, while the ENTP is fond of spontaneous adventure and sweeping, big-picture views.

At Work

ISTJs are commitment-minded people, so when they set their gaze on a goal, they’ll do everything in their power to achieve it. This approach makes them reliable and productive, but it can also paint them as bossy and distant. On the other hand, the ENTP is charismatic and adaptable, which allows them to connect with other team members. Together, these two personality types can lay the groundwork for both productivity and support in the workplace.


The ISTJ – ENFJ relationship compatibility is in the red zone of our chart, but this doesn’t mean they can’t learn to collaborate. It just takes work and understanding from both parties.


The ISTJ personality is practical, detail-oriented, and grounded in the present. They don’t use emotions when making decisions, and they enjoy a structured environment.

Therefore, in a relationship with an ENFJ, an extrovert with Intuition and Feeling preferences, the ISTJ must learn to accept their partner’s focus on emotion and appreciation for abstract ideas. They can also inspire the ENFJ to be more grounded, while learning to be more relaxed themselves.


As long as they steer clear of criticism and accept their ENFJ friend’s abstract ponderings, ISTJs can be good friends with the warm and empathetic ENFJ personality. On the same note, the ENFJ should learn to not take the ISTJ’s bluntness as a personal attack and appreciate the ISTJ’s example of how to be more grounded.

At Work

Both ISTJs and ENFJs are interested in creating an organized and productive work environment. However, the ENFJ is friendlier and relates more easily to others (whether coworkers, superiors, or customers), while the ISTJ will probably be the one devising strategies and problem-solving with their logical thinking.


Besides the fact that they are both introverts, these two types of the 16 personalities system don’t have much in common (hence their placement in the red zone). Of course, with a bit of work and an open-mind, ISTJs and INFPs can learn to be in a successful relationship with each other.


INFPs are true romantics; they fall in love easily and like to be swept off their feet by the perfect partner. In contrast, ISTJs’ practical nature keeps them reserved and patient in their pursuit of love. Therefore, there won’t be too many sparks flying between these two personality types (at least in the beginning).

In addition, ISTJs value structure, traditions, and commitment. This can scare away the dreamer INFP who needs to feel free to explore to their heart’s content. At their best, these two can learn what makes them tick and help each other become more well-rounded.


As friends, these two types understand and respect one another’s need for time alone. But it can be difficult to go beyond that. The idealistic and freedom-loving INFP is not good at finishing projects and tends to procrastinate when they don’t feel inspired. This can be irritating for the ISTJ, who is focused on completing tasks and organization.

At Work

ISTJs enjoy a well-organized work environment and promote rational thinking based on facts and details. On the other hand, INFPs are creative thinkers who look for innovative solutions and thrive in a flexible environment. They can also be procrastinators, so it helps to have an ISTJ around to make them more committed to achieving their goals.


In the personality type indicator system, the ISTJ and the ENFP are complete opposites. They share no preferences, which is why their relationship compatibility is in the red.


In true “opposites attract” fashion, a romantic relationship between an ISTJ and an ENFP will be anything but boring! Since it’s difficult to find common ground, the relationship won’t be without frustrations from both sides. Still, if both partners keep an open mind and learn to appreciate each other’s point of view, there is a lot of room for growth.


For ISTJ types who are interested in new experiences, an ENFP friend can be the ideal person to have around. The ENFP will push the ISTJ out of their comfort zone and into adventurous challenges and fun experiences. Of course, the ISTJ still needs space and time alone, so the ENFP must be considerate of these preferences.

At Work

People-centered, curious, and spontaneous, the ENFP will quickly become the center of attention at work. This works nicely for the ISTJ who likes space and time to think, but they may get frustrated by the ENFP’s lack of organization or attention to detail. As they navigate their way through collaboration, these two can learn to play on their strengths and shore up each other’s weaknesses.
