I'll get back to you..It's an interesting question. I often talk to my friends/sister about socionics but it's really hard to convince them that it's real or explain the difference between types etc. I guess it comes with practice, but we also need better resources than we already have.
It was all way too much for me at first to get my head around...(nvm why, it just was..). I was just happy when I discovered Rebelondeck's posts and probably read every single one he ever posted as well as screenshotted them...because he was CLEVER and he simplified socionics down to something that resembled science/ or a sort of general wisdom. Most of what I know about socionics I know from him..then there are my own observations from typing and also stuff I pick up from various people on here. But yeah I'll try to explain why you are possiblyy SEE later.
