MBTI – Cognitive Function DEVELOPMENT





 PREVIOUS: Attractivenessthe INF

SITEs: “Learn all about MBTI

Mental Symmetry

Birth to about age 13
We develop our DOM function. It’s the most obvious in children, & the one they will have the most control of throughout life. Glimpses of their auxiliary function will be seen as well, but underdeveloped & not quite balanced

13 to about 21
The AUX function develops, in support of the DOM. For Introverts, the AUX will be shown to the outside world, while the Dom is less visible – at first

DOM & AUX are the 2 most relied-on functions, & make up about 90% of our personality type

21 to mid-40s
The TER function develops. While this will never be as strong as the first 2, it will help balance them out if developed properly

40s through 70s
The INF is gradually developed. For many it will always be a weak point in the personality, since it’s rarely going to be as easy to use as the first 2. However, with proper practice & persistence, we can greatly benefit from its addition

✦ Normal personality growth happens in stages which correspond to the order of our specific functional stack, so by observation we can see which stage someone happens to be in, because chances are they’ll gravitate to people who have a weaker function higher up in their stack, in an unconscious attempt to learn from them.

EXP: An INTP (Ti-Ne-Si-Fe) who is having trouble using their Si-Tert successfully (lazy, sloppy, procrastinating….) may hang out with an ESFJ (Fe-Si-Ne-Ti) or an ISFJ (Si-Fe-Ti-Ne) to see how those people organize / structure their life.

Se will look to SPs or NPs for adaptability
Si will look to SJs or NJs for discipline

Ne will look tot NPs or SPs for openness
Ni will look to NJs or SJs for expertise

Te will look to TJs or TPs for competence
Ti will look to TPs or TJs for self-possession

Fe will look to FJs or FPs for compassion
Fi will look to FPs or FJs for moral virtue

✦ Any Undeveloped Function (BY eilamona )
▸ Usage is in its raw, basic form
▸ Usage is usually one-dimensional & not adaptable (like: an undeveloped inferior Ne who only sees negative possibilities)
▸Is present but untrusted & undervalued by the user

▸ User who doesn’t recognizes an undeveloped function’s influence on their thought process will have little or no control over it
▸ When it becomes prominent, usually under pressure, the undeveloped function is explosive & uncontrollable (INF in “Grip”)

Any Developed Function
▸ It’s multi-faceted, so can be used in many complex ways
▸ It easily adapts to & supports many different life situations

▸ The user has mastered the function, trusts their ability to use it in their thinking, & consciously consults it often
▸ Being comfortable with the function, the user relies on it to make important decisions in life

Any Unhealthy Function
It’s used in negative, unproductive & destructive ways, toward self & others
▸ It’s often used in isolation, not interacting with other functions of opposite E / I preferences (such as a DOM/TER loop with an undeveloped AUX), unless other functions are also unhealthy

EXP: An INFJ girl with an unhealthy Ni-Fe “knows” that her friend is dating a ‘wrong’ person who’s likely to cheat. So she plans & proceeds to sabotage the friend’s relationship through manipulation, because she’s sure she knows what’s best, without asking what the friend actually wants (true story)

Any Healthy Function
It’s used in beneficial, productive ways (to self/ others)
▸ It works well with other functions around it

 If the same INFJ girl has a healthy Ni-Fe, she may notice that her friend’s new romantic partner is very non-committal. She cares about her friend & her ‘wants’, so decides to talk to her about it.
It turns out the friend is already aware, & explains the partner will be leaving the country in a few months anyway, so it’s ok. The INF respects her friend’s choice, and will be supportive in future if/when she may have relationship problems, but will never be the cause of them!

PREVIOUS: Dangerous Types #1

 ⛩ INTUITIVE / THINKING Types (MORE for the healthy version of each)

▪︎ Destructive INTPs are haughty & careless, drifting in their own little world. They avoid responsibilities, neglecting or ignoring family & anyone in their care. They scoff at moral codes, treating people like tools or objects to use & throw away, talking harshly & not caring about the hurt they cause.
They like to toy with others just to see what happens, since to them everything is about cause-&-effect or experimentation. They look down on ‘the masses’ for being less intellectual or ‘enlightened’. They don’t care what others do as long as they’re left alone, & anyone who tries to connect with them is avoided or treated with silent hostility

▪︎ Destructive ENTPs are arrogant, dishonest & self-centered. They live in a constant haze of ideas, which is not bad by itself, but this type will go to any lengths to chase those ideas. They may lie, trick or steal from others to get what’s needed to reach their next goal. They may also enjoy messing with people – like Trolling is considered ‘good fun’ – unaffected by any pain they cause. They’re totally undependable, abandoning ‘loved ones’ to follow ever-changing whims. They’re a charming & good-hearted friend to anyone showing interest in their plans, but the minute that person rejects an idea, the ENTP will mock, bully or discriminate against them

▪︎ Destructive INTJs are cold, arrogant & controlling. They’re contemptuous of & condescending to anyone who doesn’t value their same vision or sense of logic. They believe their intuition & predictions are always right, stubbornly sticking to their ideas without ever considering other viewpoints. They get agitated & vindictive toward anyone who criticizes or contradicts them

They may enjoy belittling others & taking sarcastic jabs, considering themselves more enlightened & intelligent than the rest of humanity. They either isolate because they’re so disappointed in their fellow man, or they’ll micro-manage everyone, forcing them to obey every command. If their vision is evil, they’ll be terrifyingly effective at forming plans that would be disastrous for humanity

▪︎ Destructive ENTJs are dominating, aggressive & quick-tempered. They have a clear vision for the future & will try to force everyone to follow their ideas, ignoring other points of view. Everyone else’s feelings & values are considered stupid, since they’re extremely proud of their ‘logical superiority’. They have a fiery temper & can be intimidating bullies, using a quick wit & cold hard logic as weapons to humiliate & silence opponents. They consider themselves above emotions & subjective feelings but will become moody, wallowing in self-pity when things don’t go their way. They enjoy using their intuitive perceptions to play mean tricks. Domination is their game & they get increasingly power-hungry as they devolve.

= = = = = =


▪︎ Destructive INFPs are self-absorbed & self-righteous, wavering between being passive & blatantly judgmental. They love living in fantasy, ignoring practical realities of daily life, neglecting or abandon family & anyone else who cares about them. They feel morally superior or more ‘righteous’ than anyone else, so married to their idealism that everyone in the real world seems flawed & disappointing. They isolate & silently criticize, over time becoming harsher & more condemning. They can get so obsessed with their own inner imagination that they avoid or berate anyone who tries to find a way into their heart

▪︎ Destructive ENFPs are manipulative, self-absorbed & disloyal. They believe the world revolves around their interests & ideas, only ‘caring’ about others based on how much they can get from them. They jump from one idea or relationship to the next, flaking on plans & shirking responsibilities without a second thought. Inspiration & stimulation is everything, & they’ll try to grab them any way possible, even by deceit or immoral acts. They’re so sure of their own visions that they lash out at anyone who opposes them or questions their abilities. They ignore physical needs, & can become more self-destructive as health & nutritional needs are neglected

▪︎ Destructive INFJs are manipulative, scheming & self-righteous. Above all, they want to fulfill their vision for the future, going to any lengths to reach their goals, using people in the process. They rationalize their actions based on ‘the end justifying the means’, not valuing human interactions, living in a subjective fantasy world.

They consider themselves more broad-minded than others, assuming any input from the outside is worthless. When they hurt someone they don’t feel guilty, but will try to avoid that person, to not face their own wrongdoings. In ‘close’ relationships they’re often passive-aggressive, using people’s shortcomings against them for blackmail. When called out, they’ll slide into self-pity, & shut out anyone who doesn’t show them complete approval

▪︎ Destructive ENFJs are dramatic, overbearing & manipulative. They like to influence or push people into conforming to their opinions & “vision”. They’re convinced their way is always best, so anyone who disregards their ‘friendly’ advice is bullied passive-aggressively. They respect rank & authority, treating those people with respect & eager attentiveness, while looking down on anyone they feel is less ‘sophisticated’. They share other people’s secrets without remorse, pick on the underdog, & kiss up to anyone who can help them advance a vision or idea for the future. They’ll seem incredibly warm & exuberant in person, then ridicule & mock you to others behind your back.





🙋🏻‍♀️ SENSATE / THINKING Types (MORE for the healthy version of each)

▪︎ Destructive ISTPs are cold, self-destructive & indulgent. They can be ruthlessly logical in pursuit of their own pleasure & at the expense of anyone in their way. They ignore their moral compass & have no concern for the welfare or feelings of others. They keep to themselves & scorn attachments to others, only wanting to get ahead or enjoy sensational thrills, even if it harms themselves or others. They’re calculating & selfish, easily angered by anyone who tries to connects with them. Evil ISTPs make perfect mercenaries.

▪︎ Destructive ESTPs chase thrills, opportunities & pleasure, at the expense of anyone in their way. They’re excellent manipulators, who don’t hesitate to swindle, cheat or lie to get what they want. They have no regard for the feelings & values of other, & ignore all moral standards that may cross their mind. Their code is: Life is for taking advantage & living to the fullest, even if it means leaving a trail of broken hearts & wounded souls. They get a thrill out of negative or positive attention, & enjoy bullying or annoying others for the rush it gives them

▪︎ Destructive ISTJs have usually been raised in a corrupt family or societal system, accepting its unethical values & traditions without question, & have no problem forcing others to accept those same principles. Any question, skepticism or defiance is instantly squashed, since there’s only one way to do things – their’s. They’ll destroy people they see as threats, including those who are completely harmless. They want control the outside world, & will try to force it to conform to their routine or set of rules. Their own security outweighs everyone else’s welfare, & they have no empathy for emotions, ideas or rules other than their own. They’re harsh, aloof & hyper-critical of any procedure outside their set routine

▪︎ Destructive ESTJs are dictatorial, aggressive & controlling. They’re convinced they know what’s best for everyone, & it’s the only way. They deny having any moral compass, disregarding the feelings & values of others in favor of their own rigid views, only trusting their own experience. They push hard to achieve their goals without thinking thru their choices, so they steamroll everyone to get things done, never considering alternate viewpoints or the moral implications of their actions. They may be loyal to a corrupt system or authority, & suppress anyone who questions or stands up to that authority. They make fun of others’ emotions & beliefs, but are free to have temper tantrums & emotional overreactions.

= = = = = =


▪︎ Destructive ISFPs are self-serving, judgmental & indulgent. They can easily get lost in self-pity & bitterness over all sorts of imagined or misread slights, flipping from passive-aggressive coldness to self-righteous indignation. They live for the moment & are extremely reckless – habitually over-eating /shopping/ drinking/drugging…. without considering how it’ll affect themselves or others. They’re easily enraged by people who don’t understand their ‘intense emotional reactions’, even tho they’re never actually verbalized. Anyone they let in is at the mercy of their ever-changing moods, & they can decide to shut people out entirely if they can’t get their complete approval. They’re never swayed by logical arguments or reasonable discussion.

▪︎ Destructive ESFPs are impulsive, vain & self-absorbed, chasing attention & sensation at all costs. They hate anything or anyone that can upstage them, but react passive-aggressively toward someone they think may steal their spotlight. Their life is ruled by subjective emotions, & logical arguments or constructive criticism are dramatically avoided. One minute they’ll be madly in love, the next they can ditch a partners or cheat on them, because they ‘feel trapped’. They jump from one exciting thrill to another, without concern for the people they harm along the way

▪︎ Destructive ISFJs believe everyone must instantly conform to their own form of traditions & values. They may seem friendly at first, but behind a soft-spoken persona they’re manipulative & passive-aggressive. Anyone rebelling against tradition or interrupting their rigid routine will get shut out without a second thought, or sneakily get the ‘offending’ person punished in some way. They only do nice things for people to be validated & praises, but hateful when they don’t get the positive reaction they were expecting. When anyone questions them, they retreat into self-pity & guilt trips. They’re hard workers, relentless in their sense of duty, even if it’s to undermine authority or corrupt social structures

▪︎ Destructive ESFJs are manipulative, controlling & prone to gossip. They take on the beliefs of those around them, & bully people who function outside that value system. They’ll mock, ridicule or gaslight anyone who doesn’t follow their traditionally accepted views or doesn’t follow ‘the rules’, even those that are corrupt. They’re “teacher’s pet”, constantly trying to get praise from everyone, especially someone they respect, & will have a pity-party whenever they don’t get it. They easily get enraged about any imagined slight, or anything that takes attention away from themselves. They love to spread rumors if it helps gain approval from authority, being passive-aggressive, two-faced & dishonest.

NEXT: Destructive types #2



PREVIOUS: Attractiveness /Ennea

SITE: From ENFP Mod (scroll way down)



REVIEW: Enneagram is split into 3 centers for a reason. Each group represents an emotion & body part.

How we respond to everything indicates our “core center” location.

Heart / ‘love’ types (2-3-4) are all about how others react to them
They’re the most “needy,” always wanting something from someone else – admiration, attention, devotion, empathy, inclusion, love, praise, to be needed. Yes, even the 4. It’s all about how they are rejecting me. They bristle when their reputation is attacked or are accused of doing something, & defend their actions with what a ‘caring’ person they are

Head / ‘fear’ types (5-6-7) chronically over-think everything
They process new information by taking a step back to think about it They’re fear-based, though they may not realize it. Driven by apprehension about things – even the 7, who’s running away from fear of being trapped in a situation that’s not “fun”

Gut types / ‘anger’ types (8-9-1) live & react by gut-instinct
“I just knew what to do” is their most common comment, because they have a literal physical reaction to the world that keeps slamming into them. It’s an instinctive sense of NOPE or I MUST ACT. No hesitation, they just launch into a reaction (attack, numb, fight)


Enneagram 1: Most likely TJs, by far the most typical being ISTJ, since the ‘duty’ of the 1 pairs naturally with its duty-driven mentality.
IXFJ is somewhat less common but also possible. INFJs are likely, because Ni is prone to the same high idealism (too-high expectations) like the 1. 

Enneagram 2: Most likely EXFJ, because the parental aspect of #2 has a natural similarity with Fe-dom.
IXFJ is next, & then EXFPs. IXFP 2s are possible but rarer, since 2 & Fi are somewhat at odds 

Enneagram 3: EXTJ, EXFJ  / EXTP, EXFP / IXTJ.
The emotional detachment of the 3 fits best with Te-Dom, but can also be effective with a Fe-Dom core.
3s create an ambitious & flashy IXTJ. IXFJ is possible but less likely than EXFJ, since the 3 is a workaholic, & Introverts find it harder to maintain the energy it requires

Enneagram 4: IFP by a mile, because 4 is the embodiment of Fi – taken to emotional extremes.
INFJ is also common, Ni & 4 being a natural combination. Sometimes EXFJ or INTJ.
EXFP is a little less likely but still possible, especially with a 3 wing & an sx subtype.

Enneagram 5: Definitely INTP, since it’s almost exactly like the 5 – analytical, detached, objective, secretive, unemotional).
EXTJ, because frankly it goes with any high thinking function.
IXTJ,  ENTP & ESTP are ‘iffy’ since Se wants to engage with the outer world & 5 would rather watch from a bench

Enneagram 6: Goes well with every single type. Also, factor in the statistics that say 6 is one of the most common type, so the odds of it being a core or a fix are high.
6w5s pair naturally with thinking types, 6w7 is most common in EPs, but again… possible for anyone

Enneagram 7: ENXP, ESXP / ISXP.  The stereotype for EXFPs & 7s is that they’re both easily distracted, avoid pain, never finishing anything, are thrill-seekers, adventurous, & fun-loving. If a 7 thinks they’re an INFP, they’re probably a mistyped ENFP. 7 & Se are a natural mix, so only MAYBE an ISFP

Enneagram 8: EXTJ & INTJ / ESTP, ENTP, ESFP / ISTP. Rarely NF & never SFJ.
8 cores are unemotional, aware of power dynamics, bluntly assess others, earthy & sensual, with severe problems figuring out their more vulnerable feelings. This doesn’t mesh well with NF types (a rare ENFJ-8 might be an exception), & never IXFX.

Enneagram 9: Can be any type, like the 6  – it’s common all across the board.

⬆️ Long chart: ONLY one person’s opinion. EXP: This blog writer is an ENFJ – Ennea 8, but this is considered rare.




PREVIOUS: M vs F Brains #8

REVIEW: Relationship stages // Continuum





1. Sanity – The ability to distinguish between reality & fantasy
2. Psychological health – A person with good psychological health is more stable, positive & easier to live with

3. Assertive boundary (B) – a form of Personal Bs, expressed in actions
EnneaType: 1s & 8s have the strongest active boundary function, with an internal reference frame of reality, good at pushing their beliefs into the external world
MBTI: T + J gives strong assertive Bs (ENTJ & ESTJ, INTJ & ISTJ)

4. Non-reactive boundary – also a form of personal Bs, but it’s to not take on the fight. Instead, it’s being able to ignore the whole thing (big or small) & move on. It’s expert at conserving energy by not reacting – a preservation mechanism.
EnneaWings: 5w4 & 5w6, 8w9 & 9w8 – are the strongest
MBTI: I-TP (ISTP & INTP) are the strongest

5. Human Depth
We are complicated & easily insulted. Most people seem to think there’s so much more to them than others realize OR that everyone’s just like themselves. However, MBTI shows that –
• Thinkers have more depth in the world of the mechanical
• Feelers have more depth in the world of the living
• iNtuitives are better at abstract, imaginative thinking
• Sensers are better at taking in & processing information through the 5 senses

6. Intelligence – women want a smart partner more than men do
• Men are more visual, so care more about looks than women (proven scientifically)
• Some men are very proud &/or dominant types,  so need to feel smarter than their woman. If a potential partner is much smarter, it could be a deal-breaker
• Women go more by personality, which includes intelligence. so a smart man is never a deal-breaker

7. Brain-side orientation
Opposites attract – someone who mostly uses the Left brain is strangely drawn to someone who mainly uses the Right side. It doesn’t have to be an exact 1-1 correlation, it just needs it to be decent. People who are balanced, with only a slight left side domination (say 55%), can be with a wider range of people.  (Right vs Left sides)

8. Speed
: of action, decision making, physical movements & thinking.
Enneagram Instinctual Variants: – Sexual (sx) brings massive speed,  Social (so) gives some, & Self-preservation (sp) slows things down

HIGH: 2w1, 2w3 / 3w2, 3w4 / 4w3 (burst quality) / 6w7 / 7w6, 7w8 / 8w7
MODERATE: 1w2 / 4w5 (burt) / 6w5 / 8w9
Burst quality depends a lot on the persons’ mood or mental stateattractiveness

9. General physical attraction
• good posture, good skin
• right ratios in face & body
• slim, tall (usually, not always)
• muscular, + other signs of health &/or fertility

10. Personal physical attraction – its purpose is to even out one’s own extremes of some characteristic. The farther away from the “preferable average” of a given trait is, the more compelled a person will be to find a partner that cancels out that extreme, so their combination creates a “healthy average”

11. Genetic smell (immune system switches)
A collection of genes called The Major Histo-compatibility Complex (MHC) coordinates our immune system, & also decides how we smell.
Here too, opposites attract. We like people who have different ‘switches’ in their immune system from ours, & we can tell that by their smell. Our opposites also help to produce healthier offspring. This preference might prevents incest, since we’re less attracted to ‘like’ types

12. Ns and Ss mostly attract each other
This is the exception the opposites-attract rule. Normally, people with these opposing functions are not drawn to each other.
However some Ns & Ss do form a successful relationship that last a life-time, BUT only if they match each other very well on other criteria (OR if the N is used to having their S/N side discounted or abused – as so many ACoAs do!)

Points 4 & 9 are directly related to MBTI type

Points 1 & 3 / 10 & 12 are not. (Though “Sanity” is weakly correlated, since more neurotic types like Ennea 4′s often have mental problems)

• Points 1 & 9 are about the brain / 10 & 12 are about the body
• Points 1, 2 & 3 are ‘invisible’ things unknown to humans, but incorporate some commonly known things

OTHER influences on attractiveness, commonly known & also impossible to scientifically pin down or define:
— character / confidence (big one!) / how funny someone is / how big
— honesty / maturity / street smarts / wit…..

Male vs Female BRAINS (Part 8)


SITE: “Are male and female brains really different?

 tend to have more fully developed organizational skills, combining analytical & intuitive thinking.

M: are faster to absorb information, & are optimized for motor skills, so they react faster.  EXP: If a male sees a ball on the ground, he’ll probably kick it, while a woman is more likely to pick it up

M: tend to have better spatial abilities. Because they have a thinner parietal region of the brain than women, it’s easier for them to visualize rotating 3D objects

F: find it harder to mentally rotate objects – because of a thicker parietal region of the brain (More.…)

Research has shown that babies as young as 5 months can visualize an image, negating any idea these abilities were created by environmental influences

M: better at the exact sciences. They’re geared slightly more toward math because of much larger inferior-parietal lobules (IPL) which is thought to influence visual perception, math & geometry ability

PS: The IPL is the area of Einstein’s brain discovered to be abnormally large. Brain areas thought to control these skills mature in boys about 4 years earlier than in girls

F: better at the social sciences. The IPL also processes sensory information, & the larger right side in women allows them to focus on specific stimuli, such as a baby crying in the night (IMAGE ▲)

Even at 24 hours after birth gender differences emerge:
: the male brain is adapted for understanding & building systems.
EXP: Male infants look longer at inanimate mobiles, & later gravitate to action toys

F : the female brain is adapted to ’empathy’
EXP: Female infants look longer at faces, & later gravitate to dolls

In other research, vasopressin in women increased peace-making behavior, & both oxytocin & vasopressin caused them to treat computer partners more like humans.
In men, vasopressin increased reciprocation of cooperation from both human & computer partners.

M: Male rats and male humans are more likely to navigate by dead reckoning – knowing which way is north, east, south and west.
F: Female humans are more likely to navigate through landmarks – go up to this 7-11, turn left…..


One study shoved that women’s performance on math & verbal tests is best at higher temperatures (More.…)
M: while men perform best on the same tests at lower environmental temps

F: Better at distinguish between subtle shades of primary colors
M: Far more likely to have some form of color blindness, usually genetic (rarely in women).
BUT are better able to pick up on sudden movements & identify rapidly changing images

In general – smaller fingers have a finer sense of touch (tactile acuity), with more closely spaced sensory receptors to pick up a wider variety of external stimulii. Research indicates it’s fingertip size, not gender that makes the difference. Because women usually have smaller hands, they’re better at distinguishing surfaces than most men, but men with small fingertips are just as discerning.

M : Male hearing is weaker, in general. They’re 5 1/2x more likely to lose their hearing (may be partly from things like smoking, noise exposure & cardiovascular risk factors)

F : Women hear sounds that men can’t. At all ages, they have better hearing at frequencies above 2,000 Hz, but with age, are less able than men to hear low frequencies (1,000 to 2,000 Hz)

Women smell things better that men. On average, they have 43% more cells & almost 50% more neurons in their olfactory centers than males. (Originally it may have helped women choose the best mates for reproduction)

Women tend to have more sensitive palates, with more taste buds. About 35% are “supertasters,” identifying flavors such as bitter, sweet & sour more intensely than others. (Only 15% of men are).
Also, women of childbearing age have stronger taste-sensitivity than younger or older ones, especially during pregnancy.
