How to Spot an INTJ Among Other Personality Types

INTJ Key Difference Featured

INTJs (also known as The Strategist) are innovative, dedicated perfectionists, who sometimes like to make people feel uncomfortable with their infamous death stare. The INTJ is one of the rarest personality types, making up about 1.5% of the population. They are ingenious, structured, and analytical, due to their Intuitive (N), Introverted (I), Thinking (T), and Judging (J) preferences. You can easily spot an INTJ if you try to find the quiet genius in the room. But what happens when you compare the INTJ to the rest of the types? How do you spot the differences between an INTJ and, say, an ISFJ? Or an ISFP? Is it something in their mannerisms, style, or appearance? Or is there a more subtle way of noticing their individuality?

In order to get a better understanding of the INTJ type, we need to look at how they compare against other types. We’ll explore their differences and similarities to give you an insightful perspective into why INTJs are the way they are.

INTJ Characteristics

INTJs are most likely to be described as quiet geniuses, strategists, and perfectionists. They’re typically easy to spot – they usually use concise and terse statements, and are extremely knowledgeable. But they aren’t know-it-alls per se, because they aren’t in the habit of parading their intellectual advantages over others. Here are some things that can help you spot an INTJ:

  • Introverted and don’t want to be the center of attention
  • Independent and self-assured
  • Humored by sarcastic and witty remarks
  • Snarky, sometimes with a dark sense of humor
  • In love with strategic games (and winning them!)
  • Likely to be clueless about how they make people feel

How Do INTJs Compare to Other Personality Types?

Each of the 16 personality types is made up of 4 preferences in a specific order. These preferences are important in defining what each type is like. They are:

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

The building blocks of any personality are the so-called “cognitive functions.” These are extremely important in making up the way a type responds to the world around them and the information they absorb. These functions can be aimed inward (like INTJ’s Introverted Intuition) or outward (Extroverted Feeling, for example). Each type uses four of them in a strict hierarchical order. Given all of this information, we thought it’s best to go even deeper and compare INTJs to each individual type and present you with any similarities and differences they have. All types are also divided into four categories, according to their temperament types.

INTJs vs SJ Temperament Types

The SJ Pragmatist Temperament includes The Administrator (ESTJ), The Consul (ESFJ), The Defender (ISFJ), and The Examiner (ISTJ). Types sharing this temperament are typically thinkers, they are pragmatists, organized, neat, and prefer to follow traditions and established rules. They understand society to need some form of structure to operate efficiently. And in a way, INTJs agree with these ordered lifestyles, but they disagree that there should be a single norm for everyone to follow. INTJs always look for ways to improve the current state of the world and offer elegant new solutions to societal problems. Even though INTJs have a Judging preference, they still see things differently from the viewpoint of the Pragmatists.


The Administrator (ESTJ) of the 16 personalities is given its name for their value for security. ESTJs have a great sense of duty and are one of the most responsible personality types. They value tradition and are extremely loyal individuals. They have admirable organizational abilities, prioritize structure and easily bring order to a chaotic environment. They feel fulfilled when they have done their job thoroughly and brilliantly. They set high standards for themselves, as well as others. Their efforts are easily recognized by their superiors and often open doors for positions of greater power and more commitment. ESTJs are natural leaders and have all the qualities to become successful managers.

ESTJs are thorough and disciplined leaders who respect people who can follow projects to their conclusion. They notice efficiency in others and respect people who share their dedication to a task. They have deeply ingrained standards and beliefs. Sometimes this can make them look stubborn, especially in the face of the flexible and expansive Strategist. The ideas and innovative projects of The Strategist type can seem like a sign of rebellion against the norms that the one pragmatic and traditional ESTJ lives by. Sometimes, The Administrator can become too focused on the importance of their personal beliefs and can become rigid.

INTJs aren’t as focused on becoming model citizens as ESTJs are. The Strategist type aims to inspire positive change and development in the existing world, and aren’t normally satisfied with life the way it is. They have a pressing desire to manifest their progressive ideas into the present life. A few things they absolutely share with ESTJs are their seriousness, their unbreakable focus on a goal, and their “can-do” attitude. In fact, these two types could make an incredibly productive team if they choose to do so.


The ESFJ, also called The Consul, can be noticed by their kindness and desire to care for other people. Like ESTJs they value stability and security, however, they view life from their Feeling core and their drive to establish meaningful connections with others. They are good at providing both practical and emotional support to their friends, largely due to their unique combination of Sensing (S), Feeling (F), and Judging (J) preferences. ESFJs also tend to put others’ needs above their own and find satisfaction in being “givers.” This can sometimes be harmful to them, as they tend to neglect their inner needs.

The INTJ personality type couldn’t be any more different from ESFJs. For one, if you’re trying to find out how to spot an INTJ, know they are extremely individualistic and care deeply for their personal space. They don’t particularly like it when people are being emotional around them, partly because they don’t know how to deal with hyper emotionality, and partly because they feel like it can be extremely overpowering. They’d rather keep their feelings private and express them only with a handful of trusted friends. They are well aware that emotions are powerful tools for manipulation and, as The Strategists, they realize emotions can be a liability. ESFJs often seek the approval of others, whereas INTJs are more independent. They don’t struggle to be liked the way an ESFJ does.

INTJ and ESFJ have some similarities in terms of how they handle their responsibilities and work – both are organized and serious about finishing their tasks. Both enjoy variety in their working schedule and are responsible and dependable employees. They don’t have trouble bringing a project to a close and they usually do it masterfully.


ISTJs, aka The Examiner, is serious, dependant, and motivated. They are excellent at completing tasks and have great follow-up skills. When they set their mind to something, there’s little that can stop them from achieving it. They are logical and organized and have a deep respect for those who use concrete facts and rational thinking. They have extremely high standards for their family, friends, and colleagues, as well as for themselves. They enjoy digging into details and don’t mind professions that require methodical and thorough research. They are dependable and can be someone’s rock if necessary.

A lot of ISTJ’s beliefs are centered around a logical lifestyle, which also fits in well with an INTJ’s view of the world. INTJs can have a deep respect for ISTJ’s work politics and would be honored to have them as employees. This is largely due to the fact that INTJ’s intuitively understand The Examiner’s priorities and can see that their Sensor (S) preference is an extreme benefit – whatever details the INTJ misses, the ISTJ can spot instantly. Both are also extremely introverted types and understand each other’s strengths and weaknesses of this disposition.

The Examiner is extremely observant, objective and can make decisions based on hard facts. They have a great sense of what’s right and wrong and can quickly judge a situation’s outcome. Because of this, they have a strong opinion on how a task should be done, and often like to think they know the best way of doing it. This is in great part because ISTJs are right more than they’re wrong, which further boosts their confidence. They also dislike doing or dealing with things that make little sense, like abstract art for example, or things that rely heavily on the emotional response of a crowd. That’s why some of INTJ’s original and progressive ideas can seem pointless to them, as they prefer to follow an already established model of living.


The last of the SJ Temperament types is the ISFJThe Defender. They are extremely emotional and empathetic people, are aware of other people’s feelings as their own. This is due to the combination of their Feeling and Sensing preferences – they are both highly observant of others’ feelings and reactions. They also have outstanding memory when it comes to things that are important to them. They are in tune with their surroundings due to the Sensor preference and use their senses to get excellent spatial awareness. Because of this, they can’t really read between the lines or understand abstract or metaphorical explanations. Sometimes, they just can’t get the hint, which creates the potential for an argument – and ISFJs are horrendously appalled by criticism. They can’t deal with conflict or confrontation.

So far, you can probably spot many differences between the INTJ mastermind and ISFJs. The INTJ talents have a lot to do with the ability of The Strategist type to detach from emotional involvement when dealing with day-to-day activities. This means that in situations that require dealing with confrontation, they aren’t offended by any constructive feedback coming their way. They view life as a sort of chess game, and understand that putting yourself first is a way of survival. They also wouldn’t typically put the needs of others above their own, as an ISFJ would. The Strategist has a deeply ingrained sense of independence and views that as a strength.

If we were to look at any similarities between INTJ vs. ISFJ, we could agree wholeheartedly that they are organized, responsible and deliberate. Both think sequentially and like to live a life that’s structured and organized. Chaos isn’t to their taste. They enjoy ticking things off a list and prefer completing tasks, rather than starting them. They might even use step-by-step methods to ensure they’re progressing with a task, as opposed to chaotically juggling between a few jobs.

INTJs vs SP Temperament Types

The SP Originator Temperament includes four of the 16 types: The Persuader (ESTP), The Entertainer (ESFP), The Craftsman (ISTP), and The Artist (ISFP). The Originators among the personality types that are easy to notice – they’re artistically inclined, they love to have fun and be surrounded by people. They are adventurers who like to collect experiences that can be turned into fascinating stories. They live for the present and take everything as it comes, without dwelling on the past or worrying about the future. Sometimes, this lack of organizational skills can have negative effects on their lives, and they might struggle to complete tasks, to concentrate, or be punctual. INTJs appreciate their spirit and enthusiasm for living their eccentric lives, but apart from that, they find most of their ideas and thinking foreign.


ESTP, also referred to as The Persuader, is a personal relations specialist. Much like the rest of the SP temperament types, this one is quick at turning any stranger into a friend. They’re extremely easy-going, friendly, and charismatic individuals who almost have a persuasive superpower. They are excellent at convincing people to do anything, which makes them successful salespeople. It’s a special gift and yet also considered a type of manipulation. The fact is ESTPs are capable of quickly reading body language (using their Sensor preference) and pinpointing the priorities of the individual they’re talking to. They can read facial expressions and mannerisms, and might even notice some details in a person’s clothes that highlight their individuality.

ESTPs are also dramatic, both in the positive and negative sense of the word. They are quick thinkers, they like movement and gesticulations, they can be loud and overall don’t mind being in the limelight. They also like to take risks and deal with crisis situations well. This again has a lot to do with their Sensing (S) preference, making them great improvisers who are extremely aware of the here and now, and of their reflexes. Most people of the SP temperament live life as though it’s played out on a stage. They like to think everything should be fun and they have a carefree approach to life.

The NT temperament and the SP temperament have a few similarities, mainly their brilliant brains and their active approach to problem-solving. They can never get bored if they’re paired up in a team. But apart from these things, an INTJ in a group of SP-temperamental people can be spotted easily. For one, they stand out with their quiet, unapproachable exterior and their disinterest in social affairs. They might even have a stark visual contrast to ESTPs, as people with the SP temperament can be eccentric, while an INTJ outfit can blend easily with the crowd.


ESFP or The Entertainer is probably the most gregarious of all the types. They are unique, spontaneous, and optimistic. They love fun no less than their ESTP friends and they are incredibly talented. They live life like they’re the true stars of the show and enjoy being the center of attention. In life, they aim to be appreciated and understood and feel truly special when someone can recognize their unique talents. They can make powerful friendships with people. They are likely to develop strong bonds with those who can appreciate them for who they are.

ESFPs have a great sense of aesthetics and enjoy being surrounded by beautiful things. INTJs and ESFPs are different both in their preferences and generally. ESFPs dislike theory and logical challenges, while INTJs thrive when using their rational and analytical skills. ESFPs are realistic and live in the present, they live day by day, while INTJs like to plan things out and always have one eye on the future. ESFPs are popular and have admirable people skills, they’re well-liked by most people they meet, while INTJs aren’t everyone’s cup of tea. ESFPs need social interaction in order to feel energized, while INTJs prefer to spend time by themselves.

Nonetheless, INTJs and ESFPs have some similarities. Both hate mundane activities and meaningless professions that bring them little satisfaction or potential for personal growth. Both are independent and resourceful and like to bring new ideas to the table. Overall, you’d be able to easily recognize the INTJ type when in the presence of an ESFP, regardless of the few similarities they share.


ISTP, also known as The Craftsman, is a jack-of-all-trades – ISTPs can easily switch between tasks and often prove to be good at multiple things. They are the maestros and are extremely proficient in their desired occupation. Some might even say that ISTPs are workaholics, often devoting their lifetime to experiments in their favored sphere of interest. ISTPs need to find their true calling, otherwise, their lives quickly become boring and meaningless. They have that in common with INTJs, who share a similar disregard for ordinary professions that lack a deeper meaning.

ISTPs share many similarities with INTJs – they share the same passion for work and dislike of hierarchies, and they’re both independent, determined, and self-confident. Even though there are many similarities between the two types, their models of structuring their work are different. ISTPs don’t have any difficulties absorbing theoretical material, but they are more likely to find it pointless. They have a hands-on approach to their work and they value information that can be useful to their practical experiments. In a way, studying something they can’t smell, see, touch, or hear is useless to them. INTJs couldn’t be any more different than that. They love abstract information and philosophical discussions and can usually develop excellent plans and ideas.

Furthermore, ISTPs are result-oriented and have a desire to see immediate returns on their efforts. This is largely due to their Sensor preference which makes them prone to using their five senses and turns them into practical and resourceful individuals. ISTPs also live in the here and now, in the present, unlike INTJs who constantly think about the future. Both types are excellent problem solvers with well-developed analytical skills.


ISFPs also referred to as The Artist, are an aesthetically inclined, free-spirited, and creative individual. They are gifted with abstract ideas, and can also dip into their Sensor nature to appreciate things that can be experienced through the five senses. This makes them great for careers in art, for example as painters, photographers, or even curators – their sense of composition and style is one of a kind. They also need freedom at their desired workplace and can’t be tied to the same schedule every week. They don’t work particularly well in a team and would rather work on their project solo. They need personal space to develop their ingenious creativity, and can rarely find people who can share their unique perspectives.

INTJs share a similar passion for their own ideas. Much like The Artist type, they need space to experiment and brainstorm and they find value in time spent by themselves. They’re also quiet and reserved like ISFPs and have original and unconventional thoughts. However, The Strategist always has a plan and wants to know where things are headed. ISFPs, on the other hand, live in the present and like to take things slow, without putting too much pressure on themselves. INTJs think everything through very carefully and can sometimes be inflexible. INTJs are also natural leaders, while ISFP desires neither to lead nor follow.

Many people might struggle to see the difference between these two types, mainly because they look so similar on the surface. They both have quiet and serious exteriors. They both have ingenious and even futuristic ideas that are often ahead of their time. But they operate differently and this can be easily noticed. We shouldn’t forget that the ISFP has a Feeling core and makes a lot of their decisions based on their personal subjective opinion. INTJs, on the other hand, view life from the prism of logic and reason and they always rely on their rational mind when dealing with a problem.

INTJs vs NT Temperament Types

INTJ (The Strategist) is part of the NT Analyzer Temperament. They share this temperament with The Chief (ENTJ), The Originator (ENTP), and The Logician (INTP). These types are characterized by their logical and analytical thinking, their admirable knowledge and proficiency in their chosen profession, as well as their dedication and ability to focus on a complicated task for extended periods of time. NT Temperament types also have the incredible ability to take in huge amounts of descriptive and heavy information, with much better ease than the other types. They owe that to their Intuitive and Thinking Preferences, which are their main drives.


INTJ and ENTJ have a lot of similarities, and share three preferences – Intuition, Thinking, and Judging. They also share the exact same cognitive functions (albeit in a different order). This can be a useful example of how the different order of functions can fundamentally change the behavior of a type under the same Temperament.

ENTJ, known as The Chief, has Extroverted Thinking as their dominant function. And extroversion truly defines this overly analytical and organized type. ENTJs have a tendency of being controlling of their subordinates and are particular about the way a task should be performed. They are extremely self-confident and driven to turn their ideas into facts. They enjoy theorizing on various subjects but would be even more satisfied seeing these concepts come to fruition. They don’t want to spend hours on end waffling about the possibilities and the potential of something. They want to make it happen and they know the exact way it should happen.

Much like INTJs, they have little patience for incompetence and absent-mindedness. ENTJs are “executives” and they can be brutally honest about their disagreeing points of view. They are thick-skinned and aren’t averse to being criticized, in fact, they are often impressed by people who can express their disagreements as eloquently as them. INTJs have a similar understanding to ENTJs, but their need to manage and control everyone is less obvious. They are slightly more level-headed than ENTJs who can be considered “type A.” All in all, INTJs recognize a job well done and on an occasion when someone proves incompetent, they wouldn’t take it as a personal offense, whereas an ENTJ is likely to do so.


ENTP, also referred to as The Originator, is enthusiastic, curious, and crafty. They prioritize getting along with people and take their relationships seriously. They are flexible and have diverse interests. They enjoy inspiring others and can serve as motivational and inspirational figures for everyone around them. They enjoy a challenge and like to debate the outcomes of different scenarios with others. They are natural leaders, who truly understand the difference between being in charge and being in control. They understand the responsibility leaders carry, and the amount of pressure leadership comes with. That’s not to say they would refuse a leadership position if given the chance, of course.

ENTPs are also extremely good at resisting control from others and often have an “I’m above it” attitude, especially in the face of a bully. ENTPs would never be truly happy in regimented and confined occupations, as they need the space and freedom to create. They don’t like a routined profession and look for deep meaning and satisfaction in their careers. They have that in common with INTJs, who also wouldn’t be happy doing any ol’ job. Actually, INTJ’s strength is in generating ideas and possibilities, and that’s about all they have in common with ENTPs.

INTJs value structure and like it when their ideas follow a detailed plan of action. INTJs are doers and are excellent at taking anything that comes their way and placing it in a rational system. They also feel frequently misunderstood, and often place the blame on whoever doesn’t “get them.” They rarely express the flexibility that ENTPs exemplify so effortlessly and, in fact, they view it as messy and somewhat inadequate. Given their difficulty to express themselves, INTJs may sometimes come across as snobbish or arrogant.


INTPs, also known as The Logician, are brilliant and ingenious. Like the INTJ they have a knack for logical challenges. They also trust their personal opinions and insights above everyone else’s and can sometimes appear detached and uninvolved. The similarities continue – INTPs and INTJs both value knowledge and skill. They both prefer to work alone and feel like that’s when they do their best work. They also really despise mundane details. INTJs and INTPs do have a lot in common, and if you’re looking to spot the INTJ in a crowd of INTPs, you’ll need to take a close look at their differences.

Unlike INTJs, who are born to lead and take charge of large groups of people, INTPs have the qualities of a good leader but have little desire to become one. Moreover, INTPs aren’t usually interested in leadership, creating an even trickier situation for themselves. INTPs seek total autonomy at their occupation, and this independent streak can also categorize them as eccentric. They like to come up with complicated theories and abstractions, which not everyone has the capacity to understand. They are also likely to put less focus on things such as customs, traditions, or social status. This creates a complex and temperamental personality type.

INTJs are runner-up introverts in comparison to INTPs. Even INTJs would like to have some close and personal relationships, while INTPs aren’t as interested. They truly have a hard time communicating their thoughts and most times they don’t want to share them. They truly put intelligence and logic on a pedestal. INTPs can spend a lot of their time in their own heads, so much so that even INTJs can notice it.

INTJs and NF Temperament Types

The NF Empath Temperament includes the following four personality types: The Optimist (ENFP), The Guide (ENFJ), The Dreamer (INFP), and The Sage (INFJ). These types are characterized by their innate generosity, love, and affection they have for others. Empath types are peaceful individuals, who prioritize interpersonal harmony. They are excellent teachers, often capable of balancing criticism and emotion to create constructive arguments. They are excellent listeners and can easily tap into their emotional core to gain an understanding of other people’s feelings. They give advice based on their wisdom and personal experience and are heart-driven. INTJs operate through logic and strategic calculation, and a lot of the NF methods of dealing with problems are unusual to them. And yet, an INTJ can learn a lot about communicating their own feelings through the help of the NF Empaths.


ENFPs (often referred to as The Optimist) are fun-loving, humoristic, charming, and warm. They are the true free spirits of the 16 types. They are curious and love talking to people. As extroverts, they always like to be part of a crowd or have a large group of friends. They like to experience new things, otherwise, they can get bored easily. They despise the mundane and aren’t particularly structured or logical. If daydreaming was a job, they’d be the first ones at the interview – ENFPs have grand visions and ideas about the world, and sometimes all this thinking can distract them. Their imagination is admirable, and yet it’s because of it that they sometimes lack focus.

INTJs on the other hand believe that the human brain has the power to overcome any difficulty. INTJs are confident and skilled and strive to achieve perfection. Much like ENFPs, they enjoy exploring various possibilities and ideas. They are fascinated when they find someone they can share this experience with. You’ll often find that even though they are opposites, ENFP and INTJ would truly like to hang out together. Even though they are quite different, they still feed off each other and find inspiration in the different ways they express themselves.

INTJ and ENFP share a dominant Intuition preference, but they express it differently. This means they’re both good at coming up with abstract concepts and they tend to think about the future a lot. The difference is that, while ENFPs are emotional, energetic, and strive to be the center of attention, INTJs prefer to have some quality time alone, working on their dreams while also laying out a structured plan on what they’re going to do next, and actually doing it. If an INTJ is orderly and serious, ENFPs are prone to distractions, spontaneity, and chaos.


ENFJs are called The Guides of the 16 Personality types. They are thoughtful and deeply concerned with the well-being of others. ENFJs are also great empaths and have no trouble understanding how other people feel, even without having to deal with the same issues. ENFJ loves to help others and inspire positive change in everyone they meet. They tend to know all kinds of people and establish meaningful connections easily. They strive to help those in need and they sometimes live vicariously through other people’s happiness. They enjoy being surrounded by people they love and who appreciate them for who they are. To ENFJs, friends can be equal to family and they feel recharged after spending time with others.

An INTJ on the other hand couldn’t be any different. INTJs are focused on their goals and tasks. They wouldn’t let things distract them so easily, and they put their ambitions on a pedestal. Sometimes, spending time getting to know people seems like a waste of time and they can constantly have thoughts about their current projects while being with friends. INTJs are also introverts and would rather keep their friendly hangouts to a group of two or three. They aren’t exactly down for a rave if you know what I mean.

On the other hand, INTJs and ENFJs do have similar ideas about how their workdays should look. Both don’t want to be tied to a 9-5 job that lacks deeper meaning. They need to feel like they’re doing something important, life-changing, and fulfilling. They need to feel they belong at their workplace, not like they are outcasts or pawns in the hands of a corporation. Both types can generate new ideas and have imaginative solutions to problems.


INFJ also referred to as The Sage of the 16 types, is complex, deep, and private. As part of the NF temperament, INFJs understand that people’s emotions are extremely important, and the INFJ’s empathetic tendencies give them their unique nickname. INFJs make it extremely easy to trust them and people often like to tell them about their problems or share deep secrets with them. INFJs feel truly appreciated when they see that someone trusts them because they value these deep and authentic relationships. INFJs have strong value systems and are highly principled. They may seem closed-off, but the truth is they’re actually sensitive and compassionate towards people. This understanding of people’s emotions makes them prone to be great leaders, but they can also be service-oriented.

INTJs also represent some powerful leadership qualities, but share few similarities with the INFJ type. Yes, they too are reserved, introspective, and often prove to be good listeners. They share three preferences with the INFJ type, but their “drive” is different. INFJs place their focus on their emotions and how they feel or make others feel, while INTJ’s central focus is their need for rational thinking and decision making based on hard facts and reason. This is a great difference between INTJ and INFJ – The Sage can’t tolerate conflict while The Strategist enjoys giving their informed opinion and openly providing constructive criticism.

This resentment of critique comes from the INFJ’s deep desire to protect themselves and sometimes leads to stubbornness and the inability to listen to their people. They may ignore the opinion of others and lead with an “I am right” attitude. This deprives them of personal growth. INTJs understand the only way to improve is to recognize their mistakes and weaknesses and work on them patiently. This may not be the easiest task for an INFJ, as they have high expectations for themselves and feel offended if someone pinpoints their flaws.


INFPs or The Dreamers, are an interesting personality type. They like to dip into the world of extroverts from time to time and need a good balance between being by themselves and seeing other people. Even though they are introverts at heart, their inability to stick to a schedule creates a craving for a more unusual lifestyle. INFPs love to have fun, and equally like to have quality time alone. They prefer to work alone and may have some issues being part of a team. At the same time, they are also deeply interested in people and often put the needs of others above their own. They’re almost a walking contradiction. The truth is, INFPs want to be seen and appreciated for who they are – loyal, devoted, warm people.

INFPs are prone to distractions and have difficulty concentrating. This has a lot to do with their Perceiving preference. Perceivers are drawn to the unexpected, spontaneous, and random events in their lives, and feel limited by routine and schedules. This of course has a flip side – they can be extremely flexible and, when aware of their strength, can even juggle multiple projects at once. They may seem flakey, when in fact they just want to keep their options open for any potential opportunities.

NT and NF preferences may be opposites, but as we all know, opposites attract. You don’t have to be exactly like someone in order to be happy with them. INTJs share their intuitive understanding of the world with INFPs and with the NF temperament types in general, but their methodical and calculated approach to problem solving is what makes them stand out.
