First things first, most people in general in my life would probably type me as an xNTJ 8. But I'll get a little more into the reasons for that below.
Family Members: So my "close" family members (mam, dad, brother) would probably type me as an 8w9 (853 tritype). They might even see a 4 fix actually, they really don't see me as all that image oriented. I've been in multiple verbal and physical altercations with them and they would probably be unable to look past that. As for MBTI, they'd probably type me as an INTJ. I imagine what I just said would be interpreted by them as some sort of Fi expression, and overall they see me as more introverted (I stay in my room a lot and I come off quite cold). They see me as almost anti-positivity which would probably be read as Fe PoLR as well. In terms of Ni-Te, they certainly recognise my naturally strategic point of view (which causes a lot of clashes I notice) and tendency to tunnel vision. They may also perhaps read Se inferior in my reluctance to do things without prior planning.
Close friends: Hmm, again probably either 8w7 or 7w8. My close friends see more my "troll" side that this forum also gets to see from time to time and they'd probably read my feisty-ness as 8 core or wing. For the tritype, they'd probably agree with triple assertive in some order. I imagine they'd type me as more of an ENTJ though, or at least be less inclined to see me as Fe PoLR. They'd probably agree with what my family sees regarding the Te-Ni, however I'm often more "open" regarding my goals in life with my close friends (even if my natural inclination is to keep these to myself) so they'd probably see more Te-Se than my family do.
School/College Acquaintances: With enneagram, they'd probably see 8 and 3 - perhaps 5 as a head fix with these people as well. MBTI INTJ would probably also be what they see. Especially in my younger years I was largely seen as overly serious, cold and reserved especially by people who didn't really get to know me very well. Any humour I tried was often in the realm of dry sarcasm. I never really went to parties or anything with classmates (I still don't honestly), and while the party thing is a stereotype of introversion/extraversion it would very likely play into their surface level analysis of me. I also would guess the fact I never really enjoyed team activities (sport. group projects, etc.) would play into their perception of introversion.
Extended Family: A lot of similarities to my other family members view of me, however the key difference is they probably see me as being even more reserved than my "close" family members. I don't really care to make the effort to reach out and communicate with them, so all interactions are usually short and brief. They'd certainly be more accustomed to me going off and doing my own thing. So yeah they'd certainly type me as an INxJ of some kind.
