Your statement tells me that you're too ignorant to consider that someone might favor their secondary function nearly as much as their primary function, and therefore have trouble differentiating which is which. I have considered multiple times that my primary function may be Ti or Ne. I used to believe it was Fi, when I knew less about MBTI. I'm practically an ambivert. The fact that I can spend a bunch of time alone and be fully content interacting with media could be indicative of an introverted, analytical nature(INTP), or of a mentally-stimulated, explorative nature(ENTP). Everything about my tendencies could point to either INTP or ENTP cognitive prefecences. However, there are small parts of either stereotyped INTP or ENTP which does not accurately fit me. I also have an affinity toward creative arts/performance and focus on individuality(INFP), but this can also closely fit an ENTP who is often stereotyped as innovative and confident. The thing is, my preferences aren't as easily fit into one of the 16 types as many others. I may think about right and wrong, morals, etc. but this is my Ti working, I believe. I don't make decisions based on feelings at all. If anything, it would only happen when I use Fe to comply with a group, which is also a bit tough for me to do sometimes since I have more of a "don't back down, and stand for what you believe" attitude. Therefore, although I once considered them, I don't think INFP/ENFP are possibilities, and I am certainly to be typed as INTP or ENTP. The thing is, my preference for Ti and Ne are so close that there is nothing left for me to base my decision on. I guess I could further evaluate my enmeagram type and them match that up with the liklihood between INTP/ENTP, but that's probably too much room for error.
