“Am I an INFP or an INFJ?” This is a question I get every day as an MBTI® practitioner and blogger. The reason this question comes up so frequently is because there are so many unreliable online tests out there. These knock-off personality quizzes claim to be as accurate as the official Myers-Briggs Type Indicator®, but they are lacking the reliability and validity testing that went into the official MBTI®. As a result, numerous people are being mistyped or getting different results each time they take the test. The most common mistype to come from these online tests is the INFP/INFJ mistype.

Why are so many INFPs and INFJs mistyped?

The majority of online tests focus on the letter dichotomies (E or I, S or N, F or T) without considering the cognitive functions. Because of this, a very slight preference towards the P dichotomy or the J dichotomy could change your entire type. This isn’t how personality typing should work. INFJs and INFPs share zero cognitive functions. Plus, to make it even more confusing, INFJs lead with a perceiving preference, and INFPs lead with a judging preference. In turn, many INFPs type as INFJs and many INFJs type as INFPs! Are you confused yet? Let’s try to simplify things!

Let’s start by taking a look at the different cognitive functions for the INFJ and the INFP.

INFJ Functions

 

INFP Functions

 

If you look closely, you can see that the INFJ uses introverted intuition (Ni), extraverted feeling (Fe), introverted thinking (Ti), and extraverted sensing (Se). The INFP uses introverted feeling (Fi), extraverted intuition (Ne), introverted sensing (Si), and extraverted thinking (Te). There is not one function that these two types share.

How INFPs and INFJs Use Intuition

INFJs lead with introverted intuition. This is their dominant function. Their #1 favorite driver. They use it so much that they probably don’t even realize they are using it. More than anything else in the world, INFJs are going to look at patterns, perspectives, and the big picture. They privately consider the purpose and meaning of life, and analyze human patterns and behaviors. They like to discard possibilities until they come to the one most likely possibility for the future. Their intuition is like a tall, narrow tree, with very deep roots. It has lots of depth, not as much breadth.

INFJs feel “detached” from the world, as if they are observing it from a distance. They “zoom out” of situations to try to see how the pieces fit into the big picture. It’s important for them to look at an idea from many angles and predict which idea has the most plausibility of becoming “real.” This is more natural to them than considering their feelings or values.

You can see the INFJ perspective of the overall meaning of things and the “big picture” in Dante Alighieri’s writings.

“Heaven wheels above you, displaying to you her eternal glories, and still your eyes are on the ground.”

INFPs do not lead with intuition. They lead with introverted feeling. Extraverted intuition is their 2nd favorite function and they enjoy using it but it’s not as automatic as feeling is. Extraverted intuition sees a multitude of ideas and possibilities in the external environment. Unlike the INFJ, who focuses on discarding possibilities until the right one is reached, an INFP adds MORE possibilities to the picture. They can see one thing and extrapolate numerous ideas and connections from that one thing. Brainstorming and bouncing from idea to idea is natural to them. Their intuition is like a tree with short roots but broad branches reaching out in many different directions. It has lots of breadth, and extrapolates many connections.

INFPs tend to feel different from the rest of the world. They have a strong individual set of morals, values, and ideals that they strive to live by. Being authentic and living in alignment with their moral-code is vital to their well-being. Their intuition gives them a creative outlook and an innate ability to see many possibilities and alternatives for the future. 

You can see the INFP feeling of “difference” beautifully described by Edgar Allan Poe, who is an INFP.

“From childhood’s hour I have not been
As others were – I have not seen.
As others saw – I could not bring

My passions from a common spring.”

How INFJs and INFPs Use Feeling

INFJs use Extraverted Feeling. This is their 2nd favorite, or auxiliary function. It balances out their intuition. INFJs notice and absorb the moods and emotions of the people around them. They usually know how to alter their behavior to promote external harmony. The INFJs feeling function is like a tree with shallow roots, but long branches reaching out and absorbing emotions and feelings everywhere around it.

INFPs use Introverted Feeling. This is their favorite function, the one they use without having to try. INFPs constantly analyze how things fit in with their value system. They have a deep, individualistic set of values that they strive to adhere to in every aspect of their lives. INFPs are independent and seek to maintain an independent moral code that is refined more and more over time. They are constantly in check with their conscience to determine if something is “right” or “wrong”. They “step into other people’s shoes” to try to understand how they would feel in their position. This is called “mirroring” emotions. INFPs feelings are extremely deep, with a lot of focus. Their feeling function is like a tall tree with deep, long roots that refine and dig deeper into the INFPs own values, morals, and emotions.

INFPs will rarely alter their ideals or identity to “smooth over” things in the outer environment. Internal harmony and authenticity will always be more of a priority than external harmony.

INFJs Tertiary Introverted Thinking and INFPs Tertiary Introverted Sensing

INFJs will use tertiary introverted thinking to connect all their ideas in a way that makes sense to them.  They strive for logical consistency and enjoy organizing thoughts in their mind and piecing together bits of information. Categorizing and sorting out information is often enjoyable for them – they enjoy understanding the principles and underlying framework for things. They also like to analyze the emotions and moods of other people so they can understand them better.

INFPs will use tertiary introverted sensing to ground all their ideas and processes with what they’ve experienced in their lives. INFPs have a certain nostalgic quality about them and like to remember what’s happened before and what they felt before. They use Si (introverted sensing) to recall numerous details about a past experience, how it made them feel, and what they learned from it. This gives them faith in their experience and an ability to remember things vividly. They often have favorite books, movies, and songs that they enjoy re-experiencing again and again. INFJs tend to have little cause for nostalgia and will usually pick a new book over re-reading a favorite.

INFJs use Introverted Thinking (Ti) as their “relief” function. During stress-free times, INFJs enjoy tinkering with ideas and principles. They enjoy doing brain-teasers and mental puzzles. They like to categorize and research.

INFPs use Introverted Sensing (Si) as their “relief” function. During stress-free times, they enjoy revisiting places they’ve been, ideas they’ve explored, or pulling information from the past or history. They can be very nostalgic and enjoy reminiscing about past experiences.

 INFJs Inferior Extraverted Sensing and INFPs inferior Extraverted Thinking

The inferior function is the least developed of all the functions for each type. It’s also the most sensitive, and the most “at odds” with the dominant function.

INFJs have inferior Extraverted Sensing (Se). They are so often “in their heads” that they can lose touch with the world around them. They can also become very frustrated if the world around them is in a chaotic, disorderly state. When under intense stress, an INFJ might fall “into the grip” of extraverted sensing, and start over-indulging in sensory pleasures; over-eating, making impulsive decisions, drinking too much, over-exercising, being impulsive and reckless.

INFJs in a healthy mood can use Se in a positive way to enjoy a hobby that calms them; some INFJs become skilled gardeners, bakers, or they might enjoy bird watching or stargazing as a way to calm down and relax.

INFPs have inferior Extraverted Thinking (Te). Because it’s inferior, they can sometimes seem irrational because all their other functions tend to “crowd it out”. Just like INFJs can be so stuck in their heads that they can walk into walls (due to inferior Se), INFPs can be so occupied with their ideals and values that they lose their logical focus (due to inferior Te). Under extreme stress, INFPs can fall “into the grip” of inferior Te. This can make them seem overly directive, harshly critical, or sarcastic. They may become obsessed with righting wrongs or fixing errors.

INFPs in a healthy mood can use Te very effectively to bring their ideas and values to life and to give them a logical direction. Te can help them to put their ideas out into the world in a convincing, rational way.
