The Myers-Briggs Type Indicator (MBTI) is a personality assessment based on the theory of cognitive preferences by Carl Jung and developed by Isabel Myers and Katharine Briggs.

It can be used as a tool to understand the ways people think.

People gather information via their senses (observation and experience) and intuition (concept and pattern).

People process information via logic (true/false and correct/incorrect) and values (right/wrong and good/bad).

Individual nervous systems are uniquely attuned to two functions: one method of gathering information (called a perceiving function) + one method of processing information (called a judging function). Bodies become accustomed to using one of those two functions to respond to their environment, and one to respond to itself. These preferences are established early in life; they do not change over time, but may be developed and emphasized in a variety of ways throughout a lifetime. Every body uses all four functions to respond to their environment, but develops favorites that their brain reinforces by building up their respective neural connections.

In MBTI, these four functions are known as:

Sensing

iNtuition

Thinking

Feeling

If you tend to use your favorite function to respond to stimulus originated outside of you, this is called Extroversion. If you tend to use your favorite function to respond to stimulus originated inside of you, this is called Introversion.

If you tend to use your favorite judging function in an extraverted way, you are called a Judger. If you tend to use your favorite perceiving function in an extraverted way, you are called a Perceiver.

Every person uses all four functions in both ways, ergo there are eight cognitive functions total. A person’s order of preference for how they use the cognitive functions to operate is known as their personality type.

In MBTI, the eight cognitive functions are known as:

extraverted Sensing (Se)

introverted Sensing (Si)

extraverted iNtuition (Ne)

introverted iNtuition (Ni)

extraverted Thinking (Te)

introverted Thinking (Ti)

extraverted Feeling (Fe)

introverted Feeling (Fi)

Each cognitive function manifests as a competency in an area:

Se- power

Si- preservation

Ne- possibility

Ni- opportunity

Te- procedure

Ti- structure

Fe- expression

Fi- evaluation

And each cognitive function translates to a condition of value:

Se- agency

Si- consistency

Ne- relevancy

Ni- potency

Te- efficacy

Ti- cogency

Fe- congruity

Fi- integrity

There are rational constraints to a person’s order of their cognitive functions (also known as the order of their function stack).

A perceiving function is followed by a judging function and vice versa (a method of input implicates a method of output).

An extraverted function is followed by an introverted function and vice versa (homeostasis necessitates feedback).

An extraverted function is not immediately followed by the corresponding introverted function and vice versa (balance maintains operation).

With these constraints, sixteen permutations are possible, resulting in sixteen personality types. They are denoted as:

INFJ

ENFJ

INFP

ENFP

ISFJ

ESFJ

ISFP

ESFP

INTJ

ENTJ

INTP

ENTP

ISTJ

ESTJ

ISTP

ESTP

As an example, an INFJ’s function stack is denoted as Ni-Fe-Ti-Se-Ne-Fi-Te-Si.

Each type is drawn to a unique theme derived from the interaction of their favorite two functions, known as the preferred function pair:

INFJ- sagacity

ENFJ- diplomacy

INFP- sincerity

ENFP- originality

ISFJ- security

ESFJ- solidarity

ISFP- virtuosity

ESFP- sensibility

INTJ- perspicacity

ENTJ- pragmaticality

INTP- coherency

ENTP- ingenuity

ISTJ- stability

ESTJ- savvy

ISTP- mastery

ESTP- dexterity

The position of a cognitive function in a function stack changes its behavior. The positions are commonly denoted as:

Dominant / leading

Auxiliary / creative

Tertiary / mobilizing

Inferior / anima

Fifth / opposing

Sixth / demonstrative

Seventh / trickster

Eighth / demon

Positions 1-4 are collectively known as the Ego. Positions 5-8 are collectively known as the Shadow. The shadow parallels the ego. Ego functions are constructive and familiar, while shadow functions are destructive and unfamiliar. Ego functions are used regularly, while shadow functions are reserved for use in distress. The preferred pair of functions of the ego and shadow (1 & 2, 5 & 6 respectively) are strengths; the remaining are weaknesses. The “outer” pair of functions of the ego and shadow (1 & 4, 5 & 8 respectively) are receptive– used to connect to the self– and the remaining are productive– used to connect to others.

A combination of development and health influence the presentation of a type. If underdeveloped or unhealthy, an individual may fall back on their shadow functions, causing them to behave like the type that mirrors them on a bad day.

The healthy/unhealthy presentations of the functions in each position are:

Dom- motivates/tempts

Aux- guides/curbs

Tert- advises/pesters

Inf- supports/distracts

5th- questions/obstructs

6th- critiques/chastises

7th- challenges/restrains

8th- pressures/threatens

An individual may experience the functions in each positions as:

Dom- orienting

Aux- directing

Tert- backing

Inf- assisting

5th- perturbing

6th- repulsing

7th- distressing

8th- devastating

When overstimulated, the dominant and tertiary functions may form a closed feedback loop. To break out of a loop, the auxiliary function must be activated.

When understimulated, the auxiliary and inferior functions may form a closed feedback loop, known as a grip. To break out of a grip, the tertiary function must be activated.

In addition to their type, a person may exhibit a partiality for their auxiliary function over their dominant function. While this does not mean their stack order is different from individuals of the same type that are partial to their dominant function, it does call for recognition of subtypes. Aux-pref subtypes appear to be more outgoing than their dom-pref counterparts because the auxiliary function connects to others. A subtype is denoted by a dash followed by the abbreviation of the preferred function. For example, and INFJ who favors their auxiliary function is denoted as INFJ-Fe.

Finally, while MBTI can be used to understand how a person takes in information and processes information, it does not speak to what drives the way a person uses that information, known as the Ego Drive. For this reason, people often supplement their MBTI type with their Enneagram or Millon types (or even their Alignments or Hogwarts Houses!)

1234 - valued (ego, constructive)

5678 - unvalued (shadow, destructive)

1256 - strong (sophisticated)

3478 - weak (rudimentary)

1278 - conscious (mental)

3456 - unconscious (vital)

1458 - accepting (independent)

2367 - producing (dependent)

12 = valued, strong, conscious (ego)

34 = valued, weak, unconscious (super-id)

56 = unvalued, strong, unconscious (id)

Sensory Sensitivities of the 16 MBTI Personality Types

Perceivers: Touch

Perception operates in the here and now, as does touch. If something is not within grasp at the same time as you, you can't feel it. Touch senses force and largely operates on an instinctual level. It is subconscious yet concrete, like perception. Perception makes us jump, like feeling a surprise touch.

Thinkers: Sight

Thinking apprehends the here, but not necessarily now, as does sight. You can only see clealry what's near you at a given time. Sight detects danger within vicinity and prompts inhibition. It is conscious yet concrete, like thought. Thought makes us pause, like spotting a snake.

Feelers: Sound

Feeling functions in the now, but not necessarily here, as does sound. You can hear something coming before it is there. Sound gives away incoming threats and stimulates impulse. It is conscious yet abstract, like feeling. Feeling makes us arouse, like hearing a scream.

Intuitives: Smell

Hi Anon!!

Well lucky for you, I am an INFJ who had a 2 year relationship with an ISTP. I've reflected on our time as partners in these posts:

How ISTPs can do better when paired with INFJs

How INFJs can do better when paired with ISTPs

My (INFJ) relationship story with an ISTP

and for fun, a meme.

I hope these provide some insight! However, I suspect you were looking for less of a personal reflection and moreso a socionics analysis, so here's that:

Each the reverse inverse of the other's ego, ISTPs and INFJs are partners and playmates. In the expanded theory of Myers-Briggs, this pairing is known as "Supplement", and in Socionics its denominated "Activation".

This pairing can resemble complements; however, these relations are somewhat less fulfilling (hence "supplementary" rather than "complementary"). Activation relationships are often romantic if both partners find each other attractive. These relationships are often very easy to start, as both partners share either extraversion or introversion. Introvert activation relationships appear reserved.(a)

When presented with the same scenario, Supplement pairs will begin reasoning from different angles but ultimately follow the same logic. It's like racing the same track but starting from opposite sides of the loop; they arrive at the same conclusion by retracing each other's path, ending up in agreement but for different reasons.

For ISTPs and INFJs, this is likely to lead to both mutual appreciation and fascination. They find each other's perspectives useful for connecting the dots. Their constructive rapport and unique affinity makes them good partners in both work and play; while they don't quite balance each other like yin and yang, they do fit together and finish each other, like yin and upsidedown yin.

While INFJs seek external harmony, ISTPs value internal consistency. The INFJ will be intrigued by the ISTP's mental frameworks, and the ISTP will be compelled by the INFJ's holistic analyses.

As a couple, the ISTP and INFJ will remain somewhat mysterious to each other, yet one will always meet the other where they are at. As two developed individuals, they will naturally have each other's backs. Where the INFJ struggles to structure their world the ISTP will step in to help, and where the ISTP lacks insight into their choices the INFJ will offer wisdom.

However, as two undeveloped individuals, the ISTP and INFJ will easily slide into codependency and contempt. The INFJ will resent the ISTP for their unwillingness to engage in emotional labor, and the ISTP will feel burdened by the INFJ's avoidance of technical labor.

To avoid these pitfalls, the INFJ will have to get their shit together, and the ISTP will have to face their wounds. The INFJ may benefit from a coach, and the ISTP needs a therapist, rather than each asking the other to fulfill that role for them. Once they address these personal liabilities, they can flourish into a fruitful interdependence where they find safety, stability, and deep trust in each other.

Thanks for the request, feel free to send more asks in the future!

I'm having a tritype crisis. I'm unsure if I'm 496 or 497

I think I have both 6 and 7 things

I'm always afraid that I'm losing my life, I'm losing possibilities. I want to have adventure (even tho I don't follow my desire, and when I do it I just go extreme) when troubles come most likely I will runaway

But, at the same time, I'm always questioning myself, others, the world itself. I'm constantly looking to feel secure, and I'm most happy when I feel protected.

So Idk hahhaha

Hey! So first off, I noticed the tritype descriptions I usually link others to have become inaccessible. Here they are on another website.

Second, it's pretty obvious you have a self-preservation instinct. This is why you're most happy when you feel protected yourself. It also seems that your desire for security comes from a discomfort with uncertainty. 6s combat fear of uncertainty by always having their defenses secured; meanwhile, 7s combat this fear by always having their escape secured.

To me, the fact that you feel guarded about the world is a symptom of your instinctual variant and is a feature of all "head" types. Any enneatype may question themself– this is not necessarily the distrust or skepticism characteristic of a 6. From what you've presented here, it doesn't sound like you have evidence indicating that your go-to strategy for dealing with fear is to hide from it or to seek it out, as a phobic and counterphobic 6 would do respectively. But you explicitly stated that you will run away from it, which is the "escape hatch" phenomena of a 7.

Imagine you are a medieval warlord. A 5 would feel protected knowing the strategy of the enemy cavalry and how to counter it. An 8 would be preparing his foot soldiers to defend the fortress, more concerned with winning the battle than with safety. A 6 would feel protected knowing their fortress is impenetrable, but a 7 would feel trapped in this fortress unless they know the way out. If you're a 7w6 (which I suspect) the strength of the fortress would comfort you, but knowing you have a secret tunnel under the fortress would reassure you. And vice-versa if you're a 6w7.

In my head, this is the archetypal ENTJ that highkey wants to fight everybody but lowkey has noble reasons for this. 8 defends, 6 reacts, 4 rebels— so they're pugnacious, testy, and somewhat insolent. On the flipside, they believe fiercely in justice, loyalty, and truth. ENTJs are already 10/10 intense but ENTJ 864 is 11/10 intense. They may seem like they want to tear the world down, but this is because they are foundationally optimistic that the world can be rebuilt into something better. So externally this ENTJ will probably look like a debater and advocate with a flair for drama and subtle aesthetic.
