You say my interpretation of Socionics? (Or were you addressing me?)
I should admit I'm still not sure what exactly this is representing (I know it's accurate and a nice looking organization as I said, but what exactly is the point? Sorry, but a lot is on my mind these days, so it's taking me time to figure what this is about).
I guess you're starting with your own type and ranking the other types in order of functional commonalities? So you have fellow extraverts on the left, and their introverted counterparts on the right. And then moving down, iNtuition moves from dominant to inferior, but since you have the extraverts on one side, that's why ENTJ (Which is really entirely in the ENTP's shadow) is next. Really, in order of function commonality, it would be ENTP, INTP, ESFJ, ISFJ, but you have the columns grouped by E/I, so the type differing only by J/P is then the next closest after it.
Then it starts over again with dominant N, but now with T/F reversed, so ENFP, etc.
I'm curious on what exactly I've said that this is based on? In the OP, I grouped the by quadras, (so again, the NTP's and SFJ's would all be in the same group. I guess that's what you did with the bolding?)
