Because he'll always fall back into saying that either the descriptions are badly written or that you haven't understood them - that is, that someone (but never he, the "person who studied this more deeply than any other person in the world") is incompetent. So how can you go anywhere? No one can.

I think a better person to ask this is Jonathan (who hasn't been around much lately), since he also read the official MBTT manuals but he doesn't seem to really care much for this issue going one way or the other. The question is really if those "clear, undisputed MBTT descriptions" are not only more complete, but actually contradict those simpler descriptions available online. If that is the case, then the next question is why that is the case.

On the other hand, I do believe that a number of the other functions are radically different, like introverted sensing.
Now you were the one to hit the nail on the head.

Where I make very similar observations to yours.

Basically, both Myers-Briggs and socionics derived their functions from Jung's, but also changing them, to varying degrees. So yes, as you say, introverted feeling is not that different for both systems because they both stayed close to Jung's concept. In the case of sensing, both introverted and extraverted, socionics has changed their definition in relation to Jung's.
