Anonymous asked: Many forums have much better (clearer, more exact, or easier to understand) definitions/descriptions of the functions than the common websites that will pop up with a quick search of cognitive functions. I know the MBTI tag frequently has scattered quoting/postings of these, but maybe since this blog is supposed to be somewhat of a directory you could compile a clean list?
That’s something that we’re working on now, anon. I think this quote captures our sentiment perfectly:
“A science can only be as clear as the basic components and definitions it has to offer concerning the basic phenomena in the reality it investigates.”

We’re also very busy with finals coming up, so we have less time to devote to this right now. We appreciate everyone’s patience and interest.
Anonymous asked: so less games for IXFJs?
On the contrary, IFJs are P dominants, one of the main demographics. ISFJs have dominant Si and INFJs, dominant Ni.
P dominants are perceiving dominants, types with a perceiving function first (Ni, Se, Si, Ne). As a mental short cut, IJs and EPs are P dominants.

In terms of functions, the majority of the video game industry caters to P and T dominants. Generally speaking, there’s a universe to explore, and/or the opportunity for problem solving. Even types with inferior T functions will use their secondary or tertiary P functions to play games. You can extend the focus to include games of all kinds to see that depending on the game, there’s something for every function.
Understanding The Model - MBTI Notation to Jungian Cognitive Functions
The four letter types are a notation created by Myers to simplify the communication of a person’s temperament. It’s a lot easier to say “I’m an ISTP,” than “My temperament is dominant introverted Thinking, auxiliary (or secondary) extraverted Sensing, tertiary introverted Intuition and inferior extraverted Feeling.” In order to know what functions are associated with each type, it’s good to understand the notation, the functional dichotomies, and how to decipher the four letter code.
There are four kinds of functions that are represented by capital letters: Thinking, Feeling, (judging functions) iNtuition, and Sensing (perceiving functions) and two orientations (the direction in which a function is focused) for said functions that are represented by lowercase letters: extraversion and introversion. For example, Se is a Sensing function, that orients itself in the external.
The functional dichotomies are as follows:
extraverted Thinking (Te) - introverted Feeling (Fi)
extraverted Feeling (Fe) - introverted Thinking (Ti)
introverted Intuition (Ni) - extraverted Sensation (Se)
introverted Sensing (Si) - extraverted Intuition (Ne)
Broadly speaking, T opposes F, and S opposes N. If one of the orientations in the dichotomy is e, the other is i. If you have Ne, you have Si, if you have Ti, you have Fe, etc.
The Code: The first letter tells you the orientation of the dominant function (and by extension, the orientation pattern your functions follow: eiei or ieie), the second letter tells you which perceiving function has dominance (N or S), the third, which judging function has dominance (T or F) and the fourth letter tells you which kind of function (J or P) is extraverted.
Here’s an example:
ISTP
Here, we have an introverted function first: _i _e _i _e
a S function higher than a N function: Si _e _i _e or _i Se _i _e
a T function higher than a F function Si Te _i _e or Ti Se _i _e
and the perceiving function is extraverted:
- which makes the S function Se: _i Se _i _e
- Se’s opposition is Ni: _i Se Ni _e
- which leaves the T function for the first spot: Ti Se Ni _e
- and the F function for the last spot Fe: Ti Se Ni Fe
ISTP: Ti Se Ni Fe
lilykit627 asked: You mentioned Je/Pe and Ji/Pi a few times. What exactly does that mean? I have not yet heard of those terms (functions?)
Je = Extraverted judging function, meaning either Te or Fe.
Pe = Extraverted perceiving function, meaning either Ne or Se.
and so on.
Anonymous asked: Are you sure Light's not an INFJ? He wanted to impose his ideals onto the world. Then again I rarely feel fictional characters make entirely good representations
Light having Fe/Ti doesn’t make nearly as much sense as him having Te/Fi. If he had Fe/Ti, he:
A. Would pay much more attention to social standards and the obvious moral problems that most people would have with his actions. Fe’s instant reaction to finding such a Death Note would be to relinquish it or destroy it, due to the socially unacceptable connotation attached to dictating who lives and dies.
B. Wouldn’t have any drive to impose it’s will on the world like that (Ti). A tertiary thinking function would also put him at a disadvantage with his mind games with L, considering L has dominant Ti and would be able to recognize and counterattack any NiTi plan Light throws at him.
C. Would much more often get other people to do things for him (something Fe would utilize). Instead, he does everything himself (Te), save for when he is incapable of doing something.
Te/Fi, on the other hand, creates a dynamic where he feels the need to Te his Fi. In other words, he has to impose his morals and what he thinks is right on the rest of the world. With that much power, he quickly becomes corrupt and his operation loses sight of it’s actual goal, with him simply becoming a greater evil extinguishing lesser evils. This is only worsened by his lack of Fe perspective. He wasn’t ready for that kind of power. His Fi wasn’t kept in check with Te, and vice versa. He didn’t have a mature level of balance between them. With more developed functions, he would have taken a much different course of action, much less susceptible to abuse and corruption.
-Sirbromanguyboy (INTP)
This video is an exemplary case of Pe (Extraverted Perceiving) misunderstanding Pi (Introverted Perceiving). It is a result of a common mistake due to a theory of mind oversight. People often either forget or do not realize that the minds of others may not operate like theirs does.
Watch as the INTP “L” and the INTJ “Light” demonstrate one common way this theory of mind mistake manifests.
Pe looks up and out to the world to internalize and think about it. Pi does the opposite, turning out to the world more for the sake of implementation. If either were to assume the other works their way, they would conclude something similar to what L, the INTP, does here. If he were looking at a cake, it would mean he was thinking about it. However, in the case of the INTJ, Light, he is merely facing the cake, not thinking about it at all. (It is also possible he made the same theory of mind oversight, and assumed people would realize that just because you are facing or “have eyes on” something doesn’t mean your attention is on it.)
“At any given moment you can Te to get the result you Fi want.”
This is an important lesson for types with dominant and secondary Fi and conversely, types with tertiary and inferior Fi.
Functions can and do grate against each other, but they can work together to get a result both parties can agree on. This is where folk wisdom phrases like “Do what you have to do now so you can do what you want later,” come from. You can’t run tirelessly towards a goal (Te) without considering if you want to go for that goal in the first place (Fi) and you can’t expect to achieve your goals (Fi) without having to have to work hard for it (Te).
You must find the balance between the two.
The sentiment in the graphic can really be applied to anyone, and hence any type, rather just “ones with Fi.”
The T/F struggle, I find, tends to be more evident in types with their judging functions in the middle. Your dominant function is so pivoted on your lower function that I think this could lend itself as the reason it’s less of a “struggle” for J doms.
Fe can want something, and Ti realize that’s not what they personally, really want, or not the best course of action, etc. etc., and reroute Fe to end the story the way you want it to end. Ti can work towards an ending without fulling utilizing Fe to get there effectively and on course.
You’re right, my analysis was shallow. It more encompassly refers to the T/F divide as a whole. I don’t agree that this struggle is more salient for EPs and IJs than EJs and IPs, though. Functional development is a bit too ambiguous to make any sort of generalization about who has more of a struggle with it.

Anonymous asked: So where's the FeTi perspective?
We’ll keep our eyes peeled, anon, don’t fret! It seems that “functional typography,” isn’t as popular on the Ti/Fe dichotomy. Feel free to submit anything if you come across it!

Extraverted Judging, when well-developed, often results in confidence derived from being able to reliably exert control over the environment to cause desired effects.
Anonymous asked: Is Tina Fey/Liz Lemon an INTJ playing an ENFP?
Tina Fey is an ENTJ. 30 Rock is loosely based on her experiences as head writer for SNL, which would indicate that she’s the basis for Liz Lemon, a caricature of an ENTJ female.
For example, here, Liz talks about finding her first gray toe knuckle hair, throwing up, (Te+Se) and how she would sacrifice lives for free cable (TeNi).
FAQ - Do “this” type and “that” type get along?
When comparing types for compatibility, there are no hard and fast rules. Good relationships come down to a genuine attempt at open and effective communication. Type parings with similar functions and/or compliment functions with supplementary levels of dominance will have a higher likelihood of compatibility than type parings that do not.
Shifting From MBTI to JCF: Why?
So the staff has requested that I write out the full case for abandoning the Myers-Briggs Type Indicator and moving forward into a typology approach centered primarily around Jungian Cognitive Functions (or JCF, as we have recently—and affectionately—taken to calling it.)
1) Changes in the meaning and interpretation of MBTI type codes:
I have to say this is a topic that hasn’t been addressed too much on internet typology forums, and I want to clear up some of the misconceptions involving terminology and so on by suggesting some standards for how to approach Jungian typology in a modern context, without the irritating bipolar dichotomy system upon which MBTI is founded.
“But wait Sim, if you don’t like MBTI, why do you use its four-letter type code labels (ENFP, ISTJ, etc.) all the time?”
Well, dear reader whose future thoughts in response to this not-yet-published article I can apparently predict clairvoyantly, I’m glad you asked that question. First and foremost it’s important to understand that modern Jungian typology has assimilated MBTI’s type labels in reference to various combinations of Jungian Cognitive Functions, and in modern practice most of the better typologists on forums are using these four-letter codes with no intention of referencing MBTI’s type profiles.
I feel like nobody has actually consciously pointed this out, and yet it’s vital to understanding what’s going on in the online typology forum community today. The fact is, it’s simply easier to say “ESTP” than “person who prefers extroverted sensing introverted thinking extroverted feeling introverted intuition.”
2) The problem with self-report:
Secondly, MBTI is a self-report instrument, which carries a number of obvious inherent flaws. As I’ve pointed out any number of times by now, self-report tests don’t account for that which the test-taker believes erroneously about himself. They can’t be counted on to produce accurate results because Jungian functions are, at their core, metaphorical representations of value systems, methods of navigating an approach to understanding the self and its relationship to the outside world.
If you don’t understand a certain sort of perspective, a test that evaluates your understanding of that perspective based on your own biased self-description of your understanding of it is not going to generate any sort of meaningful result.
I’m honestly at a loss for why nobody seems to take this into account. You guys obsess over your cognitive functions tests, your Big 5, your MBTI results, your Socionics tests—as if any of it matters to anything! If we’re going to do Jung and his work any sort of justice, we have to recognize that psychological type is simply too complex to be tested by a 20-minute multiple choice questionnaire.
3) Psychological type can’t be quantified objectively:
Sorry Te doms, I know it’s hard for you to place value on anything that can’t be objectively measured, but if that’s a deal-breaker for you, then your time would likely be more productively spent on something other than Jungian typology. We’re not working with science here; we’re working with philosophical metaphors, abstract generalized representations of the various kinds of values and self-images people use to construct their identities. That’s a REALLY complicated thing to figure out, and it’s not going to be solved by a short survey about whether or not you like to organize your desk.
I heard recently about someone claiming to be INTP in Jungian functions and yet ENTJ in MBTI. That may well be true, but the fact that the person who said it found his MBTI test result significant enough to even bother including it in the description in the first place is, unfortunately, highly representative of the vast overemphasis the online type community places on type test results. No multiple choice questionnaire can accurately test your type because you can’t accurately or objectively assess your own understanding of perspectives and mindsets you don’t understand, and don’t even REALIZE you don’t understand because you’ve never experienced them firsthand.
When I mention Jungian typology to most people who aren’t familiar with it, but have heard of the MBTI, it’s understandable that they wouldn’t be aware of what modern typology has done with MBTI’s type labels. That’s certainly a reasonable mistake, but it’s time that this nomenclature discrepancy be cleared up. “I’m ESFP” simply means “I’m an Se dominant with Fi, Te and Ni as my supporting attitudes”, not “I use more S than N/more F than T, etc.”
4) Too much focus on what, not why:
While we’re on that topic, let’s consider what MBTI was designed for. Myers and Briggs attempted to borrow (and grossly oversimplify) Jung’s ideas in order to design a quick and easy test to help people get an idea of what career path might fit them best. It asks a series of questions about what you do with your life—that was never Jung’s focus. He spent the bulk of his career researching subconscious motivations for human psychological needs and value systems: he was after why we think, feel, and behave the way we do.
For instance, why did I use the Oxford comma there? Did I want to impress you all with my sophisticated English? Did I do it just because I am personally irritated by what I see as bad English? Did I do it because having good English is valued among the people I consider peers on this forum? Did I do it because that’s what I’ve always done so it’s comfortable? I could have done it for any number of different reasons, likely a combination of several influences from different functional perspectives. If a type test asked me, “Do you use the Oxford comma?”, how would that information tell us anything relevant about my value system without knowing why I use it?
The problem with the “what” over “why” approach is that the same action can mean a million different things under different contexts and coming from different people. Functions can’t be directly observed; they have to be inferred by collecting a lot of data on a specific person over a lengthy period and coming to know his most treasured values through personal interaction and in-depth analysis of his motivations and viewpoints.
5) Jung’s ideas don’t translate coherently into bipolar dichotomies or “sliding scales”:
That’s not even getting into the myriad problems with the entire concept of using bipolar dichotomies to model personality. I get so tired of seeing people post, “Oh well I used to be a J because I used more J than P, but now I am very borderline on P/J because I do less planning”, and this is pretty much all thanks to MBTI. When you don’t even acknowledge the difference between Se/Si or Ne/Ni or Te/Ti or Fe/Fi, you’re missing the fundamental point of what each of those value systems represents.
Just the other day on PersonalityCafe I saw a post where someone claimed that Lady Gaga used to be an ISFP but has “developed into an NFP” because she’s learned to think abstractly. This is exactly the kind of crap I’m talking about. That’s what happens when an ISFP grows into tertiary Ni—it doesn’t mean she is turning into an INFP!
(On a side note, I’ve seen a lot of talk recently about how “Ne and Ni are really two sides of the same coin”, but I think this is a mistake. I think Ne and Ni contradict each other about the way to deal with abstract perceptions—I think Ne and Si are two sides of the same coin, and this is why the two always accompany each other.)
6) MBTI has created numerous misconceptions and erroneous colloquial definitions of Jungian terms:
Anyway, MBTI is also responsible for the misconception that intro/extroversion is based purely on how much social interaction you do. This couldn’t be further from the truth. E/I isn’t about being social. T/F isn’t about being an emotionless prick or an overly sensitive baby. P/J isn’t about being messy or neat, and FOR THE LOVE OF GOD, S/N is not about seeing “details vs. the big picture.”
That last one is possibly the worst thing MBTI has done to Jung’s ideas, almost single-handedly. No, you don’t need to be an N type to “see the big picture.” Hell, you don’t even need to be an N type to have a strongly developed iNtuitive function! Which leads into yet another problem…
7) MBTI ignores functional imbalances and mistypes those who emphasize tertiary over secondary:
MBTI doesn’t account for dominant/tertiary loops, because it assumes that anyone who accents his N function over his S function must be an N type, etc. This one is really pervasive—some hyper-introverted Ni+Ti INFJ with poorly developed Fe shows up and people say, “OMG HE IS MORE T THAN F, HE MUST BE INTJ”, which utterly misses the point and does this person a disservice by mistyping him and falsely attributing a Te attitude to someone whose value system has nothing to do with Te.
I’ve said it before and I’ll say it again: INTJ vs. INFJ isn’t about “more T vs. more F”; it’s about TeFi vs. FeTi. Until you guys learn this, you are just going to keep plowing into the same wall of misunderstandings and erroneous type reads.
8) There is no objective correctness in philosophy:
So how do you type people, then, if you don’t know them in depth? Well see, that’s the thing—Jungian type can’t be quantified and therefore has no objective definition. Jungian types are rather like “genres” of people, in that there’s no way to empirically assess them. They only exist as general, collective understandings among people who have studied them, and different people may disagree about a person’s type. Neither is objectively right or wrong. That is the nature of the beast. Reading types is something that happens gradually—the more you’ve done it, the faster and more accurately you can do it. The more information you obtain on a given person, the more likely your type read is to be accurate. If you’re experienced with typology, you can snap type a lot of people with relatively high accuracy, but you’re still going to be wrong sometimes—first impressions can be misleading, and there’s no simple quick fix in the form of an internet quiz that will settle the momentous question of your identity for you.
If you can’t deal with that, forget typology and go work on the hard science of mapping out the entirety of human cognition in quantifiable terms—I imagine you’ll figure it out by the year 4,000 or so. Good luck!
Until science completely figures out cognition, however, we’re going to have to settle for the imprecise and nebulous nature of philosophy and analytical psychology, which depends heavily on subjective interpretation, and thus can’t be tested meaningfully with a simple questionnaire. Don’t like it? Don’t bother with Jung.
9) MBTI creates erroneous assumptions about surface similarities between people of the same type or similar types:
Another of the more irritating problems is that MBTI results in the erroneous assumption that people of the same type all must behave similarly or possess similar surface preferences, religious/political/social beliefs, etc. I’ve lost count of how many times I’ve seen, “But he can’t be INTJ, because he doesn’t remind me of this other INTJ that I know!” or “There’s no way he’s INFP, because he’s way too rude to me to be an F!” or worse yet, “He can’t possibly be an S—he’s way too smart!”
That doesn’t mean they aren’t the same type; it means you haven’t yet recognized the similarities between their cognitive approaches because you’re too busy focusing on virtually meaningless surface differences.
10) MBTI misrepresents types that share all four function attitudes as “complete opposites” when they are nothing of the sort:
Lastly, MBTI is heavily misleading in its portrayal of types that share zero letters as “opposites.” Without JCF, it’s impossible to see how ESFJ and INTP could be categorized together—they differ on all four dichotomies, so they must be opposites, right?
Wrong. They also share all four functions attitudes {Fe, Ne, Si, Ti}. They’ll probably have trouble getting along earlier in life before their functions are differentiated, but once they grow into their full potential they become, in many respects, far more similar to each other than to types that share one, two, or even three of their MBTI letters.
Generally speaking, I still get along vastly better with ISFJs (with whom I share zero letters) than with ENTJs, with whom I share three. If you don’t understand JCF, it’s impossible to see why, and it’s impossible to have any idea what Jung was talking about or what any of this personality typing stuff is actually about if you still stick to a simplistic system designed to tell you all about your deepest personal values based on a 20-minute internet quiz.
Once again, forget what and focus on why. Once you do that, you’ll realize the massive inherent problem with type profiles, start to study Jungian Cognitive Functions, figure out your type and others’ types for real, and take off the damn training wheels.
I wonder what Carl Jung would say if he saw what has become of his original psychological types.
