"In your case, your unusually developed Fi may come from a long-standing habit of self-analysis. INTPs are commonly described as latching onto systems to analyze them, and for this reason, they like to work with systems like programming, languages, or mathematics. But many INTPs also approach themselves as a system: they approach their own psychology as almost a plaything, something to understand and master. I certainly do.
And, in a way, this does develop Fi. It doesn't seem to develop all the parts of Fi that, for instance,INFPs would develop,but it does fine-tune that sort of discernment required to understand systems that aren't cut-and-dried.
For instance, no Fi is required in mathematics. There's one right answer. There's no "better" way of getting to the answer--maybe there's a faster way, but it's not ultimately better or worse. It's the same answer.
But when you delve into psychology, everything's different. You have to notice fine details. If it weren't for my Fi, I wouldn't be able to type people based on their writing style and the feelings their approach gives off to me.I sense, in writing (which,by the way, is a very Ti method of communicating: INTPs like writing, because it gives them a chance to be comprehensive and to refine their statements more than speech ever would), more emotion and feeling (two different things)than most people can pick up. And it's because of my Fi."
Well...she's misinformed.
Self-analysis. Think of the word itself...self...analysis. Analysis as defined as "the process of separating something into individual parts, understanding their features and their relations to each other." (paraphrased collectively from several online dictionary sources). Are we really going to attribute a Feeling function to analysis, here? Just because it's analysis of
the individual? We can all look inward from time to time and I believe it's a characteristic of introverts, especially IN (because of the Intuition's role in the dom or aux slot to be comfortable with the non-concrete and theoretical and the mystic (which the inner person, soul, mind, etc, can very much so be)), to gather an understanding, more or less, of themselves earlier in life (I'll be real general and under the first 30 years).
Explanation and Expoundance:
Yes, self-discovery, just looking into yourself, is both a service provided by Ti and Fi. However, Ti's and Fi's approach are quite different in its form. Fi will look into discovering "you", yourself. What you love, what you hate. Your values. Just coming to know yourself
as a person. Ti aims to figure out how you
work. "I reacted to this and in this way...Why?" Finding your own patterns of behavior and thought processes. Could extend into emotional matters but, as a Thinking function, Ti aims to remain objective and analyze this "weird sensation". xD It's called an emotion, buddy.
Does this make sense?
Since, at the time of this post you are undecided on INFP or INTP, you have concluded you have an inner Judging function, correct? (sidepoint: Also, because of the P preference, you aren't quick to express your conclusions/judgments as the Judgers are). So, how do you judge things in your reality? By logic? It's either logical or not logical? Or more subjectively? Good/bad, like/dislike, hate/love?

About the sensing emotion in writing...And I invite [MENTION=9350]sentientsixpence[/MENTION] and [MENTION=1360]TheDaringHatTrick[/MENTION] thoughts on this, but it seems much more Fe or Ni (working with Se). Fe because it's taking in the emotion outwardly and recognizing that. Hence, the FJ's gift with discerning people's emotional states. This would give basis to the individual whom spoke with you being an INTP because she'd be using Fe. Despite it's inferior place, it'd be more used (and dare I say, developed?) than Fi because it's actually in the stack, not a shadow.
Or this occurrence can be a result from Ni and Se. Idk why I felt to include them together here. It picks up it on certain words/phrases/sentences and forms the general "impression" of, in this case, the emotion of the writer "most so then other people." Idk why but I kinda felt some INFJ in the writer of the above quote (not INXP but the user on the other forum whom the quote's from). Just me? (my Ni may be overstimulated from figuring out the thriller movie I just watched).
But I doubt it's Fi. If it is, I can argue it's accompanied with Si's data of what Fi has already experienced. So then can remember what the individual has felt before and recognize, "This writer is feeling this."
