My first guess, in INFJs, and even ENFJs for that matter (while Ti is the inferior, it’s still the sidekick judging function), is that we need to be aware of how anything that initially ‘makes sense’ to us isn’t based on objective reality so much as it makes sense according to our own experience of the world. Ti isn’t really in any managerial position, it works for Fe.
If I may butt in here, technically, I think it probably works for Ni.
Judgment functions qua cognition need a space in which to operate, it seems to me. Further, I'm pretty sure, for introverted judgment, introverted perception provides that space. Perception provides starter data, and we all knew that, but where does judgment itself form? Not decisions or rulings, but the function of judgment. I think there's some sense in which perception data instantiates judgment rulings. More importantly, judgment active amongst similarly oriented data is just that, active. Creative. Actually creating and changing itself. Judgment operating on data of an opposite orientation is static--the judgment itself doesn't develop as judgment, it just judges.
I think though there can come a time when there is some communication between the orientations, and the (Ji+Pi)+(Je+Pe) becomes some 4-way dynamic. But I don't know what that is yet, either prosaic maturity or transcendent godhood, one or the other.
It might be possible to say that feeling is feeling and orientation of judgment is something else. The interesting thing I keep reading reported about Fe is--and I paraphrase, perhaps even warp--the effort that goes into maintaining Fe rulings at the expense of passing emotion, allowing of course that the rulings can change over time as patterns of passing emotion are noted and external checks with other people are used. Fi obviously has something like this conclusion maintenance too, but there's some different nuance to the Fe method that seems like it might be important.
