The title question is:
“Do intuition and sensing play a bigger part in how we thing than thinking and feeling?”
To which the answer is, NO.
Rephrased in light of the first paragraph, the question becomes:
“Does the preferred secondary function play a bigger part in cognitive process than the preferred dominant function?”
To which the answer is, NO, under normal circumstances, and YES, when the preferred dominant function is suppressed.
In my first post in this thread, I showed how a misinterpretation can occur, gave a reason for why we often see suppression of the dominant function, and suggested how it might be recognised and corrected.
Apart from the OP's first paragraph, the main body of the post is her own observations and attempts at correlating the data.
The following are my own observations of the data:
I'm only asking because I've noticed a lot of supporting intuition users on this site identifying more as intuitive types than as feeling or thinking types.
I've probably seen that more with intuitors only because there are more intuitors on this site. But I have seen some ISTPs(who seem to be the most common sensor type on here) who seem to identify more often with Se-users than with Ti-dominants.
In these cases, we see individuals who are using their stated preferred secondary function where their stated preferred dominant function fails them. This is likely to be due to a suppression of the dominant function, and/or a misdiagnosed preference of the dominant function. It has nothing to do with the rational or arational (J or P) function playing a bigger, better or stronger part in general cognition.
For instance, INFPs labelling themselves more often as Ne-types than as Fi-types. I would think that they may identify more with ISFPs. I understand that with ENFPs, they may see some similarities in the fact that they have the same cognitive functions, but how far would actual similarities go?
If given the opportunity to express themselves without expectation or hindrance, in any situation, you will see rational dominants expressing themselves as rational dominants, and arational dominants expressing themselves as arational dominants. BUT, we all have sociological constraints and expectations placed upon us, and sometimes those restrictions require us to not display certain types of behaviour or restrict the ways we are 'allowed' to think.
To demonstrate this concept, lets look at a male who has mistyped himself as INTP, and should have been typed INFP. This person may, in effect, be saying that he perceives feeling types as feminine and, as he values his masculinity, decides to describe himself as a thinking type. The result is that he neglects his dominant function, because he's not actually a thinking type and he doesn't want to appear as a feeling type. He still has to relate to other people, so he uses his secondary function, iNtuition. (He may even recognise that he has a greater affinity for value based judgements, ie. Feeling, than most INTPs, but refuses to acknowledge it as part of his personality because he perceives it as feminine.)
The main thing that can be seen by the trained eye, is that he has not understood the MBTI course material, which in no way implies feeling as feminine.
Once this individual gains a proper understanding of feeling as the value based decision making function and release any false ideas about it being feminine, he will be able to embrace it as a part of his personality and start to identify to a greater degree with those of his dominant type. He would no long be restricted by a falsely imposed expectation. It doesn't mean that he can't make logic based Judgements, but that he prefers to make value based Judgements.
I've seen INFJs and INTJs who seem to identify well with each other as Ni-doms/Se-inferiors, even though they don't share any other cognitive function similarities, obviously.
I (being INTJ) get along great with my INFJ brother, and I don't have any issues with ENTJs. But, for the most part, I find myself in conflict with ISTJs and ESTJs because there is very little common ground. We both have Te as our secondary function, but that only allows us to talk logically with each other, it doesn't reconcile our conclusions.
Though that also makes me wonder...If intuition and sensing do play a bigger part in our cognition, then would INTPs and INFPs, for example, have a stronger way to identify with each others' brain processes even though they don't share dominant functions? And would that be different with ESFPs and ENFPs?
INTPs, INFPs, ENTPs and ENFPs are able to identify through the common Ne function, but as has already been noted, INTPs and ISTPs or ESTPs, despite having a common way of communicating, find it difficult to reconcile their conclusions.
I think I have address the entire OP thoroughly, and in conclusion I reiterate the original modified question and my answer:
“Does the preferred secondary function play a bigger part in cognitive process than the preferred dominant function?”
To which the answer is, NO, under normal circumstances, and YES, when the preferred dominant function is suppressed.
And, thank-you nevermore for providing inspiration for my case-in-point. If you're wondering what I mean, just think about how this sounds:
My Ti is definitely in charge, and I can assure you I feel more in common with iNtuitives than Thinkers generally
Were I to go through your other posts I'm sure I could find more evidence that you are Fi dominant.
