INTP as always. Over the years, I think I've shifted from being very P with very little J to it maybe being more like 2:1. I think that was always there, it's just that circumstances/upbringing led to suppression of the J tendencies. The other three are not even close to the middle.
the T/A variants are interesting (I only know about these from Jackie posting/explaining on FB). My result was a preference for A (which is also true in the T&A sense!).
Assertive individuals are emotionally stable, calm, relaxed, refuse to worry too much.
Turbulent individuals are self-conscious, care about their image, success-driven, perfectionists.
I see a strong resonance with P/J on these, though it doesn't cover everything. I also see this as being a little more behavioral than inherent. By these definitions, I used to be very T, but now, I'm much more A, albeit with a strong drive for success (although, that could be that need to feel competent, which is one of the big drivers for INTP).
I've had some training in LIFO, which is a behavioral analogue of MBTI; it's used organizations sometimes. In this system, there are four categories, and 90 points split up between them. From taking the assessment, you wind up identifying your "most preferred", "backup" and "least preferred" styles. The categories are: Supporting/giving (keyword: Excellence), Controlling/taking (keyword: Action), Conserving/Holding (keyword: Reason), and Adapting/dealing (Keyword: Harmony). These can change over time (as they are behavioral), and excesses/extremes can be moderated. My scores typically come out something like 22/26/30/12. Anyone else here done this?
