INFP Cognitive Functions: Functional Stack of the Idealist

Each MBTI personality type, including INFP, has four different Cognitive Functions that define the personality type. In simplest terms, Cognitive Functions outline how one processes and makes decisions. These are the way a person thinks, learns, and remembers.

It is interesting to discover the different Myers-Briggs personality types and identify how you may relate one to another. When creating this personality typing system, Isabel Briggs Myers expounded on the work of Carl Jung. In addition, she identified several cognitive functions.

It can also be overwhelming to discover your own. You may become suddenly quiet as you read your Myers-Briggs test results if you have INFP personality traits. What do you do with this information? Understanding cognitive functions can help you understand yourself and others on a deeper level.

INFP Cognitive Function: An Overview

INFP personality types tend to view the world with a degree of idealism, expecting to improve the world around them and leave it better than they found it. Unfortunately, INFPs can become stubbornly overwhelmed when they see their core values violated or confused.

INFP personality types are creative and want to mediate if there is a problem, but they are also quiet and can seem distant and uncaring.

So, what do you do with all this? How do you make sense of INFP functions to inform yourself about who you are and what you are best at doing? And what does INFP even mean?

The INFP Personality Code

INFP stands for:

  • Introverted
  • Intuitive
  • Feeling
  • Perceptive

Four of eight words developed in the Myers-Briggs lexicon of personality descriptions are used to describe personalities according to specific indicators. For example, the Myers-Briggs personality test recognizes that people are individuals and that, as such, they are all different.

According to Myers-Briggs, those differences can often be lumped into general categories that describe how people with different personalities think through situations, what motivates their interactions with others, and what they do when they become stressed or overwhelmed.

The four categories above combine in different ways to create 16 general personality types that can describe how most people think and behave. The INFP, for example, is often referred to as “the healer” or “the idealist.”

The INFP Personality Type

Admittedly, this concept can seem a tad overwhelming at first. It can be hard to understand how the INFP personality type functions when the descriptors seem like a list of vaguely descriptive words.

What qualities make up the INFP versus the qualities that make up the other kind of personalities? How are INFPs different?

According to the Myers-Briggs layout, personalities generally exist within four characteristics categories with two contrasting possibilities for each type. These categories then combine to describe a personality trait. Here are the classes, along with their choices:

  • Category 1: in this category, you are either an extrovert or an introvert
  • Category 2: in this category, you either sense things or intuit things
  • Category 3: in this category, you are either thinking or feeling
  • Category 4: in this category, you either use judgments or rely on your senses

You know which choices combine to make the INFP personality type. Those are listed above. But in what way do those choices interact to describe how an INFP person functions in their day-to-day life?

INFP Functions

The INFP functional stack consists of four primary functions: Introverted Feeling, Extroverted Intuition, Introverted Sensing, and Extroverted Thinking. Combined, they account for every distinct INFP trait, from their internalized view of the world to their barely perceptible preference for analytical thought.

But to fully understand all this, we must ensure we know the significance of the Meyers-Briggs functional stack.

In the Myers-Briggs understanding of personalities, the four categories combine to create a functional hierarchy that describes how the personality works and what function that personality type resorts to in certain situations.

This hierarchy is called a Functional Stack. The functional stack, as outlined below, consists of four modes:

  • Dominant function
  • Auxiliary function
  • Tertiary function
  • Inferior function

These four modes describe how an INFP thinks when faced with certain situations or choices. An INFP naturally resorts to their dominant function first, most likely, and the others follow in order. For an INFP, it looks like this:

  • The primary function is introverted feeling (Fi)
  • The auxiliary function is extroverted intuition (Ne)
  • The tertiary function is introverted sensing (Si)
  • The inferior function is extroverted thinking (Te)

This shorthand version scratches what these things mean to an INFP and how they experience the world. It is easy to break things down into formulas and acronyms, but it is very different to understand how these ideas carry over into practical life.

INFP Dominant Function

This is the thought process that an INFP personality is most likely to exhibit. Their dominant function is described as an introverted feeling. This means that INFPs internalize experiences on their own.

It takes energy for INFPs to be in groups. They want to feel their way through the world solo, even around others.

As a result of this dominant function, INFPs tend to be artistic and creative people who internalize the exterior landscape through their interior views. They see new experiences, whether in reality or a book, as a way of understanding who they are and place a high value on that understanding. Think Audrey Hepburn and Princess Diana; INFPs have complex feelings and a somewhat romanticized view of life.

Though not attracted to large groups, INFPs can form very close friendships.

However, they are not total loners. On the contrary, INFPs make strong personal relationships about which they feel a deep loyalty and commitment. But they do not gain energy from group relationships like extroverts do.

INFPs also feel a strong commitment to higher ideals, leading them to be often involved in important causes.

INFP Auxiliary Function

The auxiliary function of the INFP is extroverted intuition. If INFPs are concerned with who they are in an introverted sense, they can be extroverted in how they discover who they are. They look to the world outside themselves to inform their sense of self.

The auxiliary function of extroverted intuition, for example, drives them to value travel so highly. The new experience of different locations or even just the unique character of the journey creates new possibilities for INFPs to learn more about who they are and their identity in the world.

This may make INFPs sound scattered like they are free-associating when intuiting different ways of discussing the topic. Interpersonally, this can mean that INFPs will focus on questioning an individual, any individual, on learning about that person and their way of life.

On the negative side, this sense of exploration can make INFPs notoriously slow decision-makers. As a result, they tend to doubt their conclusions and want to learn more about whatever they are trying to decide.

INFP Tertiary Function

The third function of the INFP is introverted sensing. This function engenders itself in the intuiting, feeling, and perceiving facets of the INFP personality. Introversion with sensing manifests as:

  • A way of recalling memories that help them address situations in the future
  • A minimalist lifestyle that prefers to reuse old things for a new purpose
  • Respect for the past, including cultural traditions

INFPs value the past, especially when internalized through the first two functions. INFPs are not bound to tradition but will honor traditions they have experienced and assimilated when they believe they reflect their values and speak to the INFP’s identity.

This use of the past applies to lifestyle and memory as well. INFPs tend to have an affection for old things that express something about who they are or their lifestyle and use them for their purposes. INFPs can be found scouring thrift stores for items to reuse.

They also use their memories this way, latching onto events in their past that were particularly meaningful and internalizing them to become touchstones for evaluating how to navigate new experiences.

INFP Inferior Function

For their inferior function, INFPs have extroverted thinking. In the hierarchy, this last function tends to work subconsciously, affecting things in ways that every personality, regardless of type, is unaware of. This makes the inferior part challenging to understand but essential.

For the INFP, the extroverted thinking of their inferior function is best described by the fact that they sometimes tend to choose careers that require analytical thinking, such as:

  • Engineering
  • Math
  • Science
  • Law

You would not normally associate these careers with someone who wants to travel and experience life, yet INFPs can often be found in jobs where structure and organization matter.

In the same way that this feeling-based group of people can be seen as unfeeling because they are so quiet, they also value structure even though they are seen as disorganized. They sometimes struggle to achieve the kind of control over the chaos they want, even becoming overwhelmed by the task of it. Still, they crave it.

INFP Careers

Given that this article has discussed the functions of an INFP personality type, it is time to look at the careers most suited to an INFP. Remember that INFPs are creative and internalize their experiences. They have strong principles but can also be very focused on others, asking questions to learn about their experiences.

Look at this table to get an idea of the categories of career paths and the specific types of careers suitable within each category:

Art and Communication Science and Medicine Social Services Education
Graphic Designer Chiropractor Community Service Manager Elementary School Teacher
Photographer Massage Therapist Counselor School Counselor
Interpreter Psychologist Career Counselor Librarian
Writer Speech Pathologist Social Worker Special Ed Teacher

INFP Hobbies

Your career is not the only meaningful choice you make. What you do with your free time is at least as necessary. We all need to recharge, and knowing the activities that help us do that is good.

Just as INFPs are drawn to specific career paths, they are also drawn to certain activities. These activities tend to draw out the natural qualities of their personalities and engage them in exciting and beneficial ways. Here are some possibilities:

Artistic Hobbies

Below are artistic hobbies that INFPs will be naturally drawn to:

  1. Creative Writing – INFPs enjoy language and interact with language well, though they tend to prefer writing to verbal communication. As such, creative writing, such as fiction and poetry, is an excellent INFP pastime.
  2. Music – Many INFPs enjoy music, including creating and listening to it. Music can often be rooted in our experiences and memories, so a piece significant to an INFP can make for a great hobby.
  3. Design – Not all creative pursuits are internal. Design and decorating can be a great hobby that INFPs tend to pursue. It allows them to express themselves and have an impact on their surroundings.

Sentimental Hobbies

Below are hobbies that satisfy the sentimental INFP nature:

  1. Prayer and Meditation – INFPs tend to be deeply spiritual, so they are often drawn to quieter spiritual practices, such as prayer or meditation. This can be an excellent way for INFPs to stay balanced.
  2. Connecting with Nature – This activity can have a deeply spiritual component. INFPs can find a chance to reconnect with nature and satisfy their urge to travel by hiking and camping.
  3. Collecting – INFPs have an attachment to the past that often causes them to enjoy collecting. Whether it is postage stamps, old books, or records, INFPs can enjoy building extensive collections of things that are meaningful to them.
  4. Cooking and Baking – This hobby can be significant since we all have to eat. And while theoretically, INFPs could eat everything they cook or bake themselves, sharing food is also a meaningful way to deepen their strong bonds with other people in their lives.

Freeform Hobbies

Below are hobbies that give INFPs a sense of freedom:

  1. Dance – While dance is often seen as an intensely social activity, many INFPs enjoy dancing because it allows them to express themselves and focus on another person’s needs.
  2. Travel – This was mentioned before, but it bears repeating that discovery through travel is an essential hobby for INFPs. Whether it is a Sunday drive or a grand adventure to the Ozarks, INFPs thrive on the thrill of the journey.
  3. Gaming – Gaming has become a widespread INFP interest. Immersive video games involving roleplaying and robust story elements can be beautiful to the INFP.

INFP Personality in Relationships

One thing that everyone will wonder about at some point is the kind of person who will make a good companion for them. Whether that relationship is a friendship or a romantic partnership, most people wish they could understand their compatibility with others before searching for someone who clicks.

Whether you are looking for a friend or a partner, it can take time to find the proper connection. Knowing more about the different personality types can help you understand why certain people click while others do not. Here’s a chart of how compatible INFP is in relationships with the other personality types:

Other Personality Types and How They Relate to INFPs

In the table above, some personalities share traits with INFPs and may be empathetic friends.

  • INTP, or “the Thinker,” is a logical thinker but imaginative enough to relate to the INFP.
  • ENFP, otherwise known as “the Inspirer,” shares the creative and people-centric attributes of the INFP
  • INFJ is “the Protector,” which relates to how the INFP cares for people.

Among those you click, there are those with whom you do not. It is important to note that this does not mean you should only seek out compatible types and avoid all personality types that conflict with your personal Myers-Briggs type. Instead, it gives you more insight into potential shortcomings and areas you can work on.

There may be people with whom you are not getting along. If that is the case, take a look at their personality types.

Maybe there are some identifiable reasons why you are butting heads. Maybe there are things you can learn to improve. Here are some likely personality types that could present challenging learning opportunities for INFPs:

  • ISTJ, or “the Duty-fulfiller,” may clash with an INFP over order and the Investigator’s drive to create it everywhere.
  • ESTP, “the Doer,” finds inherent meaning in envelope-pushing thrills that may clash with the INFP’s more gentle and intuitive approach to adventure.
  • ESFJ, “the Caregiver,” may seem like a companionable choice for helping people, but the ESFJ’s sense of duty may clash with the INFP’s desire to create bonds.


“Be true to yourself” is never more appropriate than summarizing what to take away from your personality type. If you have taken a Myers-Briggs test and are in the INFP category, understanding your function stack can help you relate more clearly to the world around you. You have to know yourself first.

The best use of this knowledge is to create understanding and empathy for all personalities, including your own. People change as they grow older. Rather than putting yourself or the INFPs in your life in a box, understand who they are and let them grow and perceive life in their ways.
