Well, Wacomy - if you're not distinctly a particular type - the various online tests aren't going to help you clear it up. You'll have to work with the most developed descriptions of each type and try to decide for yourself. This profile is the most thorough INTP one I know of... Not sure about the INFP profiles.
My personal feeling is if you can't definitively identify which type you are - there really isn't any reason to worry about it. You're sitting on the cusp of the two kinds and you'll probably find facets of each which adequately describe you (both strengths and weaknesses.) If you try to label or conform yourself to a single one, you're going to be distorting how you understand yourself...
Also, I have a less substantiated theory that the more balanced individual you are, the harder it is for you to be typed... and vice verca... but I expect there are others who would take issue with that.
Hmmm... it might be helpful for you to delve into the more detailed analysis of the types functions beyond the general discussions of specific types.
Rather than challenge, I'd expand upon your theory, as I've been thinking along these lines myself.
People who fall 50/50 on every category are either A. Extremely well balanced and developed in all sets, or B. Completely undeveloped in any set.
If I recall correctly, the MBTI is simply a preference typing. We *prefer* to be introverted, there is no reason we can't be extroverted, but we tend to utilize and rely on our introversion more, thus developing that more heavily. The more extroverted behavior we apply, the more developed that function will become, and the closer to 50/50 we'll hit every time we test - hence why older people will tend to be land more 50/50 in many categories and not reliably be 'defined' inside the parameters of ESFJ/INTP letter combo's.
Of course the answers you give all depend on what you *prefer* versus what you *actually do*. I tend to alternate answers, hence inconsistent results. Sometimes I'll answer what I do, despite preference, sometimes I answer what I prefer, even if it's not what I actually do. Mostly, that depends on whether I'm not sure of my preference though.
Anyway, kind of sidetracked there. So, on the other hand, someone who's landing 50/50 could simply be entirely unsure of themselves and what they actually prefer, rather than having a well developed personality, they have an underdeveloped personality. Maybe whatever their natural preference they identify with is being overpowered by a dominating parents nature, or some such external force. Or anything, just throwing out ideas.
In the end, a well balanced answering individual who scores 50/50's across the board, could still have a preference of INTP, but be able to act within an ESFJ's standards comfortably, simply by having developed their weakspots.
Really, they should almost make people test with the idea in mind that, answer the questions in a situation where you feel most comfortable. For me, that's at home, in my room, by myself. When I answer all questions in relation to that concept, I come out as fully INTP. If I chose to answer more work related, I'll come out as more INTJ, but I'm definitely not as comfortable there, though it's not too far out of my skin. Were I to answer in a situation in a party atmosphere, my chameleon survival adaptation would kick in and I might get along fine, but my answers could be skewed, and it definitely is an uncomfortable situation for me. (Though, much of that depends on ones self awareness and realization that that *is* indeed an uncomfortable situation. So an Introvert might be able to answer just as accurately relating to an uncomfortable situation, where an E might not have an easy of a time? Not sure though.)
Anyway, I'll stop rambling... I need to get some stuff done yet this morning
I have not been pushed to that point in over 14 years and this would only be done by someone with a death wish now. I don't go out of my way to bother anyone and everyone typically does the same. Basically someone would have to annoy me to no end day after day building my very slow reserve of anger without letting up or directly threatening my life/well-being. Basically I would have to feel backed into a corner for this to happen. Otherwise my temperament depends on my level or depression. Under severe depression I am INFP/INTP. When relaxed I am my natural INTP with a bit of others mixed in there.
