But looking in terms of the OP, which specifically talks about INTJs and also about "regular INTJs" (the assumption is that they are convergent to start with), whereas bnova is suggesting that his mild schizophrenia leads him to be more "divergent."
So I then immediately ask (1) How are INTJs convergent, in bnova's view, if I want to define convergent for this discussion and (2) how would schizophrenia push an INTJ towards more divergent thinking and what would divergent mean in that context?
My take on that was that INTJs seem to have a sharp focus -- they have an internal vision that they then sharpen to very specific concrete ideas. Yes, that's in context of a Ni + Te mechanism. (this also could apply to Si + Te.)
Meanwhile, if you get Ti, you get a Ti + Pe setup (Ne or Se), which to me seems to more naturally radiate. Te seems to focus on very specific statements, it wants to crystalize things and moves from the general to the specific; Ti is looking for principles by nature, it moves from the specific to the general. That's where I think you are going with your suggestion here.
My mind is already racing on to see if even BROADER generalizations can be made though (such as with Fi and Fe).
So would it likely that:
Ji + Pe = divergent in nature
Pi + Je = convergent?
Still thinking, but that's where my process just went.
[And I guess my thought process, as you see, has trouble crystalizing into specifics: You can see that the more I think about it, the more I 'reach out' for more things to bring into a general concept, versus crystalizing into something very specific.]
