The 8 Jungian Cognitive Functions: Overview & Career Implications

A Glance into the History of the 8 Jungian Functions

Carl Jung, the famous Swiss psychiatrist, proposed his model of the eight (8) functions in his work, Psychological Types (1921). He divided the functions into two groups, extraverted (tethered in the external world) and introverted (unfolded in the inner world).

Jung’s work would later be built upon by Isabel Briggs Myers and her mother Katharine Cook Briggs, who created a personality model we know today as the Myers-Briggs Type Indicator (MBTI®). The Myers-Briggs approach used scales for Extraversion-Introversion, Sensing-Intuition and Thinking-Feeling based on Jung’s work and then added a fourth dimension of their own, Judging-Perceiving. The result is 4 different scales on which a person will be assigned one of two possible values. Thus there are 16 combinations (2 x 2 x 2 x 2 = 16).

Each of the 16 personality types have four cognitive functions in alternating directions (i.e. introverted then extraverted, or vice versa), which can be thought of as four “puzzle pieces” in a particular type. External factors such as upbringing and stress can alter the way each function manifests.

The four (4) personality scales as proposed by Briggs and Myers:

  1. Extraversion (E) – Introversion (I) → Gaining energy by interacting with other people or alone
  2. Sensing (S) – Intuition (I) → Collecting information through the senses or imagination
  3. Thinking (T) – Feeling (F) → Making decisions through logic or emotions
  4. Judging (J) – Perceiving (P) → Organizing time by using schedules or without them; result- or process-oriented

As mentioned, the first three above are based on Jung’s work with the fourth added by Myers-Briggs. According to Jung, the “cognitive functions” are the two scales of Sensing-Intuition and Thinking-Feeling. These are the ways in which humans process information and think about the world. Then each function can be expressed both in an extraverted manner or an introverted manner. As such, Jung didn’t really view people as “extraverts” and “introverts” but rather was more focused on the extraverted or introverted expression of each of the four cognitive functions.

Jungian four (4) cognitive functions stack:

Jung’s cognitive function “stack” describes the priority or order in which a person uses their cognitive functions, with Primary being the most natural and commonly used and the Inferior being the least-commonly used.

  1. Primary → Most natural (and comfortable) function; the internal “mother tongue”
  2. Auxiliary → Supporting function, usually connected with creation and job choice
  3. Tertiary → Function where individual often takes action steps to improve upon
  4. Inferior → Activates under extreme stress, generally avoided out of self-protection

Descriptions of the Eight (8) Cognitive Functions

Now let’s discuss the eight different cognitive functions originally outlined by Jung. His theory proposed that for each of the 4 functions (Sensing, Intuition, Thinking and Feeling) each person would generally either extravert (display outwardly or externally) or introvert (consider inwardly or internally) that function.

As you read below, consider each function and its expression. Are you more Se or Si? Does Te or Ti come more naturally for you?

Extraverted Sensing (Se)

Taking action, using all five senses, going forward. Se takes in the present moment in its entirety, and makes rapid decisions on the fly. During times of crisis and emergencies, individuals with primary or auxiliary Se can make the best out of the situation.

Example career areas that emphasize extraverted sensing (Se):

  • Archaeology
  • Stunt driving
  • Firefighting
  • Emergency patrol
  • Massage therapy

Introverted Sensing (Si)

Associations, metaphors, nostalgia. Si can travel back to any point in time through a single scent or sound. Important information (and sometimes interesting trivia) is stored in filing cabinets, where it can be retrieved at any later time.

Example career areas that emphasize introverted sensing (Si):

  • Museum curation
  • Interior design
  • Quantitative sciences (e.g. statistics)
  • Library sciences
  • Medical coding

Extraverted Intuition (Ne)

Brainstorming, thinking outside the box, idea generation. Ne easily hops from idea to idea, while making abstract connections. Many artists—especially poets—use significant Ne in their work. To the outside, Ne seems quick, random, and extremely “jumpy.”

Example career areas that emphasize extraverted intuition (Ne):

  • Filmmaking, concept art
  • Copywriting, art direction
  • Entrepreneurship
  • Video producer (e.g. Youtube)
  • Workshop facilitating

Introverted Intuition (Ni)

Time-space awareness, predicting the future, hunches. Ni is a far-reaching, visionary function—and can picture the future, sometimes with scary-accurate results.

Example career areas that emphasize introverted intuition (Ni):

  • Detective services, private investigation
  • Economic predictions and analysis
  • Forensic and engineering psychology
  • Public speaking, mentoring
  • Consulting, all types

Extraverted Feeling (Fe)

Expressive emotions, social norms, etiquette. Fe respects the consensus of the group, and puts harmony above personal desires. The function often acts as a mediator between groups, as it naturally puts others’ needs above its own.

Example career areas that emphasize extraverted feeling (Fe):

  • Acting, performance arts
  • Singing
  • Dance therapy
  • Television hosting
  • Public relations (PR)

Introverted Feeling (Fi)

Values, notions of “right” and “wrong,” likes and dislikes. Fi is a deeply personal and intense function that digs to the core of the human condition. Convictions, morals, and strong beliefs all fall under the Fi umbrella.

Example career areas that emphasize introverted feeling (Fi):

  • Poetry, creative writing
  • Art, various forms
  • Narrative design
  • Mental health counseling
  • Peace studies

Extraverted Thinking (Te)

Facts, pros and cons, methodological step-by-step strategies. Te respects rules and regulations—and takes great pride in a job well done. Checklists and clear-cut meeting agendas get Te’s gears going—a top-down approach floats its boat.

Example career areas that emphasize extraverted thinking (Te):

  • Accounting
  • Public and private law
  • Computer programming
  • Natural sciences, laboratory support
  • Computational mathematics

Introverted Thinking (Ti)

Iterations, holistic reasoning, agile strategies. Ti takes a bottom-up approach to problem-solving, and fixates on information management. When new data comes in that contradicts old beliefs, Ti will shift like a fluid crystalline framework.

Example career areas that emphasize introverted thinking (Ti):

  • Data analysis
  • Systems design engineering
  • Philosophy, sociology
  • Cybersecurity
  • Language translation

What are YOUR Functions and Cognitive Stack?

According to Jung’s theory, each person would essentially predominantly displaying each function (Sensing, Intuition, Thinking, Feeling) in either an extraverted or introverted manner. So of the 8 functions listed above, you’d have 4 of them. If you favor Extraverted Intuition (Ne) it doesn’t mean you can’t use Introverted Intuition (Ni) but rather just that it is less common for you and thus Ne is your primary mode of Intuition. Since Intuition and Sensing are together on scale, if you extravert your Intuition then you tend to introvert your Sensing. So you’d have Ne and Si.

Next you must consider your Thinking-Feeling scale. If this same person tends to externalize (or extravert) their Thinking then we have a Te, and thus by definition the Feeling would be introverted (Fi). So we have Ne, Si, Te, Fi.  But not necessarily in that order.

The next task is to determine which function is primary, auxiliary, tertiary and inferior. Whichever is most natural is likely the primary, and so on. This is the order of the “stack”, which of your functions comes first or primary, and which comes last or inferior. Let’s say the order in this case is was Ne, Fi, Te, Si. That translates to the ENFP personality type.

How Does this Relate to “Personality Typing”?

This is the underlying theory behind the Myers-Briggs model and behind most models that also use the 16 personality types nomenclature. There is no shortage of different “personality tests” online that you can take that will attempt to determine what your functions are (Fe vs Fi, Te vs Ti, etc.) and in what order they are “stacked”. This then determines which of the 16 types you fall into. While the tests are certainly convenient, any such self-assessment is naturally rigid and prone to testing limitations and thus is never able to get a fully-accurate picture of a human being.

Oftentimes a test may have you near the middle in one or more of the scales. Take an INTJ and INTP for example. The only difference in terms of the letters is the J vs. P at the end. However, the two types are actually much more different than would seem once you consider their functions and cognitive stack:

INTJ:

  1. Ni
  2. Te
  3. Fi
  4. Se
INTP:

  1. Ti
  2. Ne
  3. Si
  4. Fe

When you look at the above functions for each type, they don’t share ANY of the same functions – each is almost a mirror opposite of the other. What is most similar is the order or stacking of the Intuition and Thinking above Sensing and Feeling. Thus, having a better understanding of the underlying type theory here can help you not only to better understand your type, but also to determine your type should you find that you get different results from different tests or from subsequent attempts at the same test. If you find that you’re in between on one letter, look further into the cognition functions outlined above to see which seem to most accurately describe your common or default mode.

Summing Up: The 8 Jungian Functions for Career Selection

We’ve taken a look at the eight (8) Jungian functions from a careers’ perspective as well as considered how these functions align with personality type theory. As an extension of the 16 personality types, it’s yet another useful resource in the self-understanding and career direction toolbox.

Each of the 16 personality types have a stack of four functions, in descending order: primary, auxiliary, tertiary, and inferior. Typically, people select careers which focus on their strongest two; their natural strengths. The idea here is that these are areas where you will excel. Could you still be successful in a career that is more aligned with your tertiary function? Perhaps, but it would be more of an uphill battle and generally not as natural of a fit.

Want to get a better understanding of your cognitive functions or type? Start by taking a credible, reliable personality test based on the 16 types approach or one of the other popular personality testing models. Then visit our career guides page and filter to find careers that are most closely aligned with your personality type.
