This is a thing where a lot of people on the internet pretend that they do but they actually dont and sometimes does a poor job at it.
In type me threads I could write a lot about what I do use, way too much to fit for a thread.
But in "concrete non-virtual" life, I most of the time do not type anyone. Ok, actually I have some types where I click quite badly, and I only focus on recognizing these (INFJ is not one of them, otherwise I wouldnt be here), but in general I dont know what type the person is unless on a type me thread online or if the person does tell me the type. However, recently one you tuber that I watched went talking about MBTI, I paused to video, think for 30 seconds, said to myself "INTJ or INTP, not that much Introvert" and the you tuber said himself: "I scored last time as INTJ, but today as INTP and I see more myself on the INTP description than on INTJ description" and I was pretty much happy that my guess was quite accurate. On that day (it was this week), in these 30 seconds I first thought of stereotypes, he fitted the INFP one, then I revised all dichotomies (I vs E, N vs S, etc..) and realized that there was too much Ti and Te, so I switched to INTP, and then I realized that the guy had somewhat of INTJ vibe and Te vs Ti and Ne vs Ni wasnt that clear, which made me in doubt if INTJ or INTP.
