, so you'd have to decide if you really have the right order. Secondly, you have to define what a function is first. Thirdly, you'd have to account for individual differences, that is clearly some INTP's 'run' more Ne than others (entertainer INTP's do this in particular), so is the order the functions are 'used' in your nomenclature canonical, or can it be altered?
If you consult Dario Nardi's work in this, in fact he sees that predominantly INTP's use the F3, F4 and C3 regions of the brain the most. These are "Deductive Analyst, Expert Classifier and Factual Storekeeper." You don't need the definitions of these terms to see they are Ti and Si, which indicates a usage model of Ti-Si-Ne-Fe perhaps.
On Ne he observed that when brainstorming Ne dominants and auxiliaries had 'Christmas Tree" brains, which is all the regions light up asynchronously, which triggers when the person is indeed brainstorming something. So this is some kind of meta function perhaps. Likewise Ni uses all the regions of the brain but instead it is synchronous. He calls it the 'zen state'.
I'm observing these function orders through the writings of authors, as well as phenomenological introspection. I was skeptical for a while that cognitive functions had validity at all, but they're quite clearly there.
In the case of an INTP that uses a heavy amount of Ne, the Ti still comes first, and it still runs as Ti-Ne-Si-Fe, only the Ne section will likely be longer than usual. It's possible too that such an INTP could use an ENTP function order and go Ne-Ti-Fe-Si, but that is just a case of using the function order of a different type. Our type is just the most preferred function order - the default.
I of course am unsure how this would show up on a neurological reading, i.e. whether an INTP would show a synchronous brain state when engaging the Ni-Te-Fi-Se function order or whether something else would happen.
My methodology should be easy enough to use, but maybe it's harder to do for others than it is for me, as years of thinking has led me to stumble upon this particular method so it goes with what I've come to learn over that time.
Give it a go though - pick up a book, go to the start of a chapter, and try to link the first paragraph or few to a function based on the theme of what is being said, and then go onto the next section. This can be done to forum posts too, especially if they're in paragraph form.
There are no doubts in my mind any more that the function order typically suggested is the correct one.
There are some questions though of whether the function order of 4 functions extends into all 8, such that INTP = Ti-Ne-Si-Fe-Te-Ni-Se-Fi, but what I have observed in authors is that their writing cycles using only 4 functions.
If multiple people learn to do this method, we can cross-check each others' typings of authors (or otherwise) to give the idea objective validity.
(I would elaborate on how to link a short piece of writing to a cognitive function, but I do it very subjectively and then explain the reasoning situationally, but I will get something more concrete in time)
[note: I suspect that this post shows an INFJ function order moving through all 8 functions; the number of functions one progresses through seems correlated to how confident one is in the subject matter]
