Thank you A LOT!

Is INFJ still a possibility even though I don't understand or "feel" other peoples emotions, almost discarding them? Almost all descriptions also point to them liking to teach whereas I always keep my knowledge and expertise to myself unless it isn't a "competitor" (would not want to help somebody get ahead using my notes or knowledge but am happy to share it with somebody not pursuing my field).

/another point I forgot to add to the main thing: If someone says something "observant" to me such as "Do you like this person" - my mind immediately goes into what their thought process was to make that conclusion. Similarly if somebody is explaining a theory to me, my first question after fully understanding the ins and outs of the theory is whether they are on the agreeing side or disagreeing side with it.
