In this article, you’ll find a comparison of ISTJs and ENFJs across five important personality domains: Interpersonal/Communication Style, Emotional Style, Intellectual Style, and Organizational Style.

One important note: the following comparisons cannot be made simply by comparing the cognitive functions (letters) of each personality type.

For this analysis, TraitLab gathered data about personality traits from thousands of participants who identified themselves as a particular type in the 16 Personality or Myers-Briggs framework.

The comparisons here show the average similarities and differences between ISTJs and ENFJs. However, remember that all personality types are oversimplifications. For an assessment of your unique position in these areas, you’ll need a personalized assessment that doesn’t rely on personality types.

ISTJ and ENFJ Interpersonal and Communication Styles

Your particular style of communicating and interacting with others can be described fairly well by two dimensions: assertiveness and warmth.

Assertiveness describes your tendency to assert yourself, lead, and influence others in social situations, while warmth describes your tendencies to empathize and put others’ needs ahead of your own.

People with the same personality type often share some similarities in assertiveness and warmth. In the graph below, you can see where most ISTJs and most ENFJs fall along both of these dimensions.

First, take a look at where people in each type, on average, fall in this interpersonal space.

ISTJs are realists who perceive things and people clearly, without being overly optimistic. At their best, they are practical skeptics who are comfortable holding and sharing unorthodox, unpopular views. ISTJs may be overly skeptical and suspicious, and they may have difficulty trusting others. At their worst, they can struggle to make new friends and socialize, and have a hard time showing affection and admiration for others.

ENFJs often support, openly sympathize, and actively offer help to others At their best, they are gentle sympathizers, who are easily trusted and accepted. ENFJs may be overly revealing and have difficulty being alone. At their worst, they can require too much attention and admiration from others and be excessively involved in the affairs of others.

As an ISTJ, one notable difference between you and most ENFJs is in your interpersonal warmth. You are likely on the colder, more combative side of the spectrum. Compared to you and other ISTJs, ENFJs’ can sometimes feel overly focused on feelings and intentions, rather than the facts of the matter at hand.

Another important difference between you and most ENFJs is in your relative assertiveness or passivity in social situations. Like many ISTJs, you are often on the more passive, reserved side of the spectrum. In some cases, this is a perfect compliment to ENFJs’ more dominant, assertive style, and the two of you can make an effective team. However, you may find that you need to put extra effort into making your opinions heard when working with ENFJs.

ISTJ and ENFJ Emotional Styles

Another characteristic of your personality is your emotional style — your tendencies towards different kinds of moods. There are two dimensions that influence emotional style: arousal and valence.

Arousal describes your relative energy level across different situations. Those with high baseline levels of arousal tend to be generally more alert, active, and engaged, while those with a lower baseline are more reserved, subdued, and inhibited.

Valence describes whether these moods tend to be positive (pleasant) or negative (unpleasant). People with a more positively valenced style are more likely to experience emotions like joy, enthusiasm, satisfaction, and serenity. People with a more negatively valenced style are more likely to experience sadness, frustration, dissatisfaction, and anxiety.

The graph below shows where each type, on average, usually sits in this emotional space.

ISTJs have a tendency to be quiet and inhibited. Compared to most people, they can easily drift into gloom and melancholy. They see the glass as half-empty and have a more skeptical outlook and a hesitant approach to life. For better or worse, ISTJs tend to notice the negatives in most situations. In stressful times, they are more likely to withdraw quietly and retreat inward, rather than share their frustration with others.

ENFJs tend to be energetic and enthusiastic across most situations. They take on new challenges with excitement, confidence, and a sense of adventure. ENFJs are usually more optimistic than most people, and they generally feel like they can handle what life throws at them.

As with most ISTJs, you tend to be more reserved, inhibited, and quiet than most ENFJs. Between the two of you, you are more likely to need more personal space, solitude, and time to decompress. While you can tolerate long periods of calm and quiet, your ENFJ counterparts often craves more engagement and excitement. In the best cases, an ENFJ can pull you out of your comfort zone and get you out into the world, while your quiet nature helps to balance out their intensity.

Another difference between ISTJs and ENFJs in their typical emotional valence, or their tendencies towards positive and negative emotions. You and most ISTJs tend to fall on the more negative side. Compared to most ENFJs, you and most ISTJs typically experience more negative emotions like sadness, worry, frustration, and impatience. ENFJs have the opposite pattern, and they tend to gravitate toward positive emotions like enthusiasm, joy, and contentment.

These emotional differences can be subtle, but they may color how ISTJs and ENFJs process new information. You and most ISTJs are quicker to see the negatives and consider what could go wrong, while ENFJs might receive the same news with excitement and optimism.

ISTJ and ENFJ Intellectual Styles

Your intellectual style describes how you receive, process, and pursue different kinds of information. Differences in intellectual style are captured well by two dimensions: ideas and aesthetics.

Ideas describes your appetite for new information and your interest in complex, challenging material. People high on the ideas dimension have an appreciation for complexity and technical details. People lower on ideas are less interested in learning for learning’s sake, and they prefer to simplify complex topics down to the essential details.

Aesthetics captures your relative interest and sensitivity to aesthetic information and its emotional impact. People higher on the aesthetics dimension usually have strong artistic interests and a deep appreciation for beauty in many forms. Those lower on aesthetics tend to value practical application over artistic merit and usually adhere to more conventional standards of beauty.

In the graph below, you’ll see where ISTJs and ENFJs, on average, fall in this intellectual space.

ISTJs are practical realists. They focus on building practical skills and essential knowledge and are less likely to spend time learning for learning’s sake. In addition, they usually value conventional, tangible accomplishments over artistic expression and rarely feel compelled to develop a creative outlet.

ENFJs tend to be deep thinkers — bright, curious, and philosophical. They are highly receptive to new ideas and drawn to complex, abstract concepts. ENFJs enjoy taking in large amounts of information and typically have one or more creative outlets.

Like most ISTJs, you are less interested in learning purely for learning’s sake, compared to most ENFJs. You’d prefer to focus on the essentials and the practical issues at hand, while your ENFJ counterpart typically wants to dig deeper and understand the bigger picture. In conversations, you may find that your ENFJ partner often gets caught up in theoretical or abstract details, and you need to bring them back down to earth.

Another difference between ISTJs and ENFJs is their relative interest in aesthetic, artistic, and emotional experiences. As a ISTJ, you tend to be more practical and focused on tangible results, while your ENFJ counterpart is more likely to be drawn into the emotional and artistic aspects of an experience. In addition, ISTJs and ENFJs often differ in their receptivity to unconventional and eccentric ways of thinking. Like many ISTJs, you often lean towards well-worn, conventional approaches and view new alternatives with healthy skepticism. In contrast, ENFJs are quicker to do away with convention and embrace a new approach.

ISTJ and ENFJ Organizational Styles

Your organizational style describes your habits around organization and planning. Your organizational style influences how you structure your time and physical space. Differences in organizational style fall along two dimensions: industriousness and orderliness.

Industriousness describes your persistence, need for achievement, and intensity of focus. People higher on industriousness usually organize their behavior around a few important long-term goals. People lower on industriousness are usually more focused on the present and will more easily change their focus when new opportunities appear.

Orderliness describes your need for regularity, order, and structure in your environment. People higher on orderliness prefer tidy, organized physical spaces, detailed schedules, and reliable routines. People lower on orderliness can tolerate more disorganization and prefer a more spontaneous, unstructured approach.

The graph below shows the average position of ISTJs and ENFJs along these dimensions of organizational style.

Most ISTJs and ENFJs share a similar organizational style.

ISTJs and ENFJs are usually systematic and highly organized. They like setting big, long-term goals and then creating detailed plans to accomplish them. ISTJs and ENFJs are generally good at ignoring distractions and making steady progress through consistent routines and habits.

As an ISTJ, you and most ENFJs share a natural drive to achieve and perform at a high level. Both of you enjoy setting goals and pushing yourselves to accomplish them, and you likely share an interest in self-improvement and productivity strategies. As a result, you and your ENFJ counterpart can fuel each other’s ambition and keep each other accountable as you work towards your long-term goals. However, between the two of you, nobody usually reminds you to slow down and enjoy the present.

Similarly, ISTJs and ENFJs tend to be neat, tidy, and organized. You both rely on high amounts of structure and routine and compared to most people, you have lower tolerances for messiness and disorder. With a few exceptions, both of you stick closely to most social conventions and feel uncomfortable straying from them.
