I can't speak on whether or not you all actually DO have more Fi than Fe, but here's what I think anyway.
Fe is
*conscious, Fi
*isn't. Ti being
*directly opposed to Fe, it makes sense that the INTP would be consciously
AWARE of Fe, and more than that,
AWARE of his or her own limitations, (or at least "distaste") in that regard. Fi
*"operating" much like Ti, at least superficially, would seem more comfortable to the Ti-dom, and having that as an
*unconscious function, would already place it in the "ill-defined by the psyche" category - leaving it more apt to be confused with their Ti on the basis of a similar "structure."
"Fe. I know exactly what they're talking about, and I KNOW I don't do that" verses "Evaluate what is worth believing in and most important to who you really are inside" - appealing to the INTP's independence and want to "think for himself," too. I don't see why a typical [?], younger [?], especially introverted, or VERY T-ish INTP wouldn't score higher on Fi than Fe, assuming any of this makes any sense at all.
It probably doesn't help that the Fe descriptions are written more for a hypothetical Fe dom or aux, or at least someone that would be "proficient" at it - not a Ti-dom with his ego built and placed in
*direct opposition to it.
There should be a flow chart-like format for CP tests, or one with options that also give descriptions of the more "negative" (<- not the right word) manifestations (<- not the right word) of each process, I think. That creates different problems, of course, and it would be much harder to give accurate definitions, but I think it could be done. Just not by me, obviously.
* SUPPOSEDLY!
