Question regarding Fi (different use in each type)

I have a question that primarily regards to IXFPs

I haven't found any information about difference of usage between ISFPs Fi and INFPs Fi. I know it's all Fi but the functions of information gathering are different in thous two types which tells me that Fi is differently based.
Maybe that's not where the difference is but i would like to hear some description of how Fi reflects in thous two types and where is the difference (and i suspect there is a difference)

Secondary - descriptions of aux, tert, and inferior Fis - how do they work on thous places?

Also third would be the question about aux, tert. and inferior Fi
EXFP - difference between thous two aux. Fis
IXTJ - difference between thous two tert. Fis
EXTJ - difference between thous two inferior Fis

Thank you for all information you can provide here :)

I doubt there's much difference in any of the types beyond the dom/inferior, the former being sophisticated, fluid, trustworthy, etc., while the latter is rough, black-and-white (all-or-nothing), doesn't help them out a ton, etc. The aux. and tert. Fi users I doubt are really that, if even particularly, different from each other (based on IRL observations, I've generally gotten that idea, other than perhaps it is used more flexibly in the tert. ones (positive to negative), I'm not sure). Actually, some thread explaining the differences between aux. and tert. Fi would be great, because that's something I've always wondered about, and whether or not it is any imperative that there are particular differences. So much of what gets considered Fi is myth anyhow, so frankly, I find this a tough question to answer.

I think there's a greater air of independence conveyed by the Fi of the tert. Fi types, but then again, I've known some aux. Fi types who are rather like this also. The main difference between the EXFPs and IXTJs lies in their introversion/extraversion and different P functions (or differently prioritized P functions in the case of INTJs and ESFPs and ISTJs and ENFPs). The main differences between the EXTJs and IXTJs lies in I/E (although less, since those Es are less extraverted people-persons on average) and the fact that the EXTJs operate on a dominant judgement charter of decisive, goal-oriented purpose, while the IXTJs operate on a dominant perception charter of alternative-seeking, exploratory/way seeking purpose. The IXTJs tend to definitely be less people-oriented than EXFPs, but the level to which I would attribute this to their F or introversion (or hell, even enneagram) is up in the air. Most of this stuff that gets associated with the high F functions about people-loving, sociality, etc. is largely myth (or more applicable to dominant F anyhow, although not always) and usually a product of the enneagram, persona, upbringing, social anxiety, temperament, extraversion, etc. I mean, Sigmund Freud was probably an IXFP according to a famous Jungian expert, and he certainly doesn't fit any of these stereotypical F bills whatsoever - the guy was an intellectual giant and not a warm/fuzzy person.

i wouldn't go with thous traits in order to type someone. It sounds too tricky. Even if someone does makes decision based on feelings that doesn't necessarily makes a person warm and fuzzy and also even if some is a thinker doesn't mean in fits into a stereotype. Ofc i do believe stereotypes do exist for a reason but they are usually tops 50% accurate cuz every person is individual also as well as the part of a certain group. Also if feeling preferences usually reflects on a person to be warm and fuzzy, why would that mean all of them should be fuzzy? Induction seems to be the right way to get a stereotype based on observing individuals.

I think there's a greater air of independence conveyed by the Fi of the tert. Fi types, but then again, I've known some aux. Fi types who are rather like this also.

Could depend on an age of a person. With time you can develop your tert. or person can have badly developed aux.

The main difference between the EXFPs and IXTJs lies in their introversion/extraversion and different P functions (or differently prioritized P functions in the case of INTJs and ESFPs and ISTJs and ENFPs)

this was kinda my point. P functions are data gathering - so i had an idea (IDEA not a conclusion) that P functions could have an impact on how judging function works (which is in this case Fi). If you know what i mean, the way of absorbing information can effect your judging process even if it's Fi in both types. It coudl result with different conclusions and different points of view on things. And maybe, just maybe, different reflection of Fi in their behavior.
But Fi itself it's simply a function which means you are making a decision according to how you feel about it and subjectively since it's introverted function. What im talking about is probably about type differences even if they have same dom function and that dom function can be reflected differently. Ofc in the end and in essence - it's all Fi.

The main differences between the EXTJs and IXTJs lies in I/E (although less, since those Es are less extraverted people-persons on average) and the fact that the EXTJs operate on a dominant judgement charter of decisive, goal-oriented purpose, while the IXTJs operate on a dominant perception charter of alternative-seeking, exploratory/way seeking purpose.

and im gonna knock myself out every time i hear "this E type is less extroverted then the average".
So far this sentence ive heard for ENTJ, ENTP, ENFP (that was lol) and even ENFJ, once for ESFP (also LOL)...i will need soon a proper argument on why do people think so cuz it just seems they say that for every type as soon as someones extroversion comes in question. I'm kinda thinking that's rather individual and personally it seems like they are rather tricky things to decide. Hence why i am already annoyed with dichotomies I and E. Ive already pulled a line and said "dom Xi function - introvert, dom Xe function - extrovert" - which would be end of story. I would kinda understand EXTX being less extroverted cuz of their T preference so that would maybe make them less people-oriented hence less social hence maybe less extroverted.
But...i am kinda interested in your opinion about why do you think some extroverted types are less extroverted then the other E types?
I do agree with you on IXTJs maybe being less decisive and i would explain this with them being dom in P function.
Hence why would EXTJs be more decisive cuz of their dom J function.

The IXTJs tend to definitely be less people-oriented than EXFPs, but the level to which I would attribute this to their F or introversion (or hell, even enneagram) is up in the air.

i do understand your point. I know 4 INTJs. One is very social, one is like an old lady just male, one is too serious, the other is also normally social.
all ESFPs i know - well with no exception they are very social.
But...that is only from what i have seen and making a conclusion on this would be very stupid.
About maybe T types being less people-oriented makes sense to me cuz they are naturally maybe more task oriented people. But that doesn't mean task can't involve people.
I consider this as smth rather individual and it's very hard for me to say i can say smth as a rule.
Enneagram could be also one of possible explanations, but i don't know a lot about this subject to be honest. From what i have seen in people debating about it until now, i haven't exactly seen anything very reliable.
But thous things you say that would be up in the air...would you care to share them? What's on your mind?


now in general, my interest was also in Fi preforming on different places (on dom, aux, tert and inferior place in types). Nevertheless, i kinda suppose that there is a much greater difference between Fi on inferior place and Fi on aux place, then between Fi on aux. and tert. place.
And this interest is not only about Fi, but for all functions. There must be a reason and criteria on which you say "this person is IXTJ and i can see tert. Fi in them"
Even one identifies that the person uses for example Fi/Te and Ni/Se, it has to know the order. Ok, they can always recognize which one function is dom and aux cuz they are much stronger. But aren't there reasons and criteria to recognize inferior and tert in someone?

(I hope ive been at least a bit understandable - this was rather hard for me to put in words :/ i hope i haven't missed the point or just about everything)
