one of the things that has been part of the fiatmine gig i have (well, the pay is indexed on fiat) is MBTI, the Myer-Briggs personality system.

as a child i did the test and i got INTP, but when i do it now, 2x out of 3 i get INTJ. well, i guess that means that something changed in me since then. i have thought about it and i think it's that the P is observation and J is impulse and i'm more impulsive and decisive than i was back then.

the other thing that resonated was one site gave a general term for INTJ as "the mediator" and i was like, "omg, i forget how many times i got into shit over the years trying to mediate between people in conflict"

yeah, ok, i'm INTJ

introspective, intuitive, thinking, judging. my mother was ENFJ and we used to often have conflicts about exactly the fields that were different - she was more outward focused and more focused on feeling that thinking.

it's not a useless system, i think. probably can be useful to help guide an organisation. the one i work in i have definitely had issues with two specific people in it and probably they will return a test that has one or both of the last two in conflict (those are tension oriented) or the first two different (those cause misunderstanding).
