Intresting read. I kind of relate to this article but not in the introvert/extrovert way (I'm a clear introvert). I've often felt that my personality is an almost even split between thinking and feeling, and when I do take personality tests I usually get INFp, but also often times come out with INTp. Also, as far as socionics subtypes goes, I generally classify myself as a Ni subtype, but Fe subtype also makes sense, so I think being split subtype works best for me.
Does anyone else relate?
