Reading time: 5 minutes
In this article, you’ll find a comparison of INFJs and INTJs 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 INFJs and INTJs. 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.

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 INFJs and most INTJs fall along both of these dimensions.
First, take a look at where people in each type, on average, fall in this interpersonal space.
INFJs often agree, trust, and cooperate with others. At their best, they are friendly, affectionate, and bring out the warmth and sympathy in others. INFJs may be too agreeable and quick to compromise. At their worst, they may seek approval and agreement too much, and be dependent on the approval of other people.
INTJs are forthright, firm, and speak their mind directly. At their best, they are fiercely independent and unaffected by the thoughts and opinions of others. INTJs may be harsh, frank, or insensitive in their criticism of others. At their worst, they can be overly aggressive and too eager to fight and argue with others.
One notable difference between many INFJs and most INTJs is in your interpersonal warmth. Like many INFJs, you are more likely on the warmer, friendlier, more empathetic side of the spectrum. Compared to you and other INFJs, INTJs’ interpersonal style can sometimes feel distant, cold, and uninterested in your wants and needs.
Another important difference between you and most INTJs is in your relative assertiveness or passivity in social situations. Like many INFJs, you are often on the more passive, reserved side of the spectrum. In some cases, this is a perfect compliment to INTJs’ 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 INTJs.
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.
INFJs 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, INFJs 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.
INTJs tend to be reserved, laid-back, and content. They often see the glass as half-full, confident that things will eventually work out for the best. INTJs typically respond to challenges with quiet optimism and rarely become overwhelmed when things get difficult. When their efforts fail, they calmly dust themselves off and try again.
Like many INFJs, you and most INTJs tend to be on the more reserved and quiet side. You both prefer to sit back and observe, and the two of you are usually perfectly happy with lower levels of excitement and stimulation. You understand each other’s need for personal space and solitude, and you are both content to leave each other to do their own thing.
One difference between INFJs and INTJs in their typical emotional valence, or their tendencies towards positive and negative emotions. You and most INFJs tend to fall on the more negative side. Compared to most INTJs, you and most INFJs typically experience more negative emotions like sadness, worry, frustration, and impatience. INTJs 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 INFJs and INTJs process new information. You and most INFJs are quicker to see the negatives and consider what could go wrong, while INTJs might receive the same news with excitement and optimism.
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 INFJs and INTJs, on average, fall in this intellectual space.
Most INFJs and INTJs overlap heavily in their intellectual style.
INFJs and INTJs tend to be deep thinkers — bright, curious, and philosophical. They are highly receptive to new ideas and drawn to complex, abstract concepts. INFJs and INTJs enjoy taking in large amounts of information and typically have one or more creative outlets.
As an INFJ, you and many INTJs share a love of learning new, challenging ideas. You both appreciate complexity and nuance, and the two of you can spend hours discussing and debating a wide range of topics. When you are together, you often elevate the conversation to a more theoretical, philosophical level.
Likewise, both INFJs and INTJs share a deep appreciation for beauty in the natural and artistic world. Both of you can easily become absorbed in aesthetic experiences and overcome with a sense of awe and wonder. The two of you can find common ground in your love of creative expression and unconventional approaches to life’s challenges.
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 INFJs and INTJs along these dimensions of organizational style.
Most INFJs and INTJs share a similar organizational style.
INFJs and INTJs are usually systematic and highly organized. They like setting big, long-term goals and then creating detailed plans to accomplish them. INFJs and INTJs are generally good at ignoring distractions and making steady progress through consistent routines and habits.
As an INFJ, you and most INTJs 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 INTJ 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, INFJs and INTJs 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.
Most people have complex personalities and don’t fall into a single personality type.
