I have noticed certain approach/avoidance attitudes that I have toward some functions that the present theories don't color. I have never looked into Model B but was delighted to see that attitudes toward introverted and extroverted functions are a thing there.
Not gonna lie: I was drawn into Model B when I did a Google picture search and saw the Chomsky-and-Hale's-Features-like +/- symbols. It began as pure click bait for me:
If this were true, you'd likely see the manifestations of +/- of various attitudes by the environments in which the attitudes (functions) appear. There could be a somewhat predictable complimentary distribution of CT expressions.
