I would take both a bit further. A Ti-dom (my wife, at least, and the ISTP I have known closely) would go beyond the logic, and want to see how it fits into their systematic understanding of things.Y
@itselly As for Ti-Fe in your example, Ti-dom will always focus on the logic of the situation. "Is this logical?" is something a Ti-dom would be asking themselves. A Fe user would ask "How can I achieve harmony and make all sides happy?".
Fi-Te on the other hand would ask themselves "What is the right thing to do in this situation?" "Do I have any evidence to confirm that?" "Am I making the right decision?"
Fi, on the other hand, also has a system, but it's not logical, but rather, "How does this fit into what I know is good and bad, right and wrong, or where is this leading me--equitable/inequitable, happy/sad, comfortable/uncomfortable.
The inferior Fe in the Ti doms I've known tends to follow the socially accepted ways, and attempts or desires to keep the peace because upsetting that upsets their equilibrium, and that interferes with how they can process things logically. It's noise in the datastream that needs filtering. One maybe could say that Ti fights against Te by turning to Fe to smooth things over. However, under duress, it may cause a Ti-dom to resort to strongly emotional outbursts, and strong expressions of emotional language to browbeat down the offending party. (words like mean, hateful, ugly, etc. would be used--emotionally-based ones)
The inferior Te, for Fi doms tends to create the exact opposite effect, a brutal search for a stable foundation so as to protect the feeling stream. Fe is like rocks in the river that create rapids. The rapids can only be negotiated with strong show of force, and quite tumultuously. One could say that Fi fights against Fe by turning to Te to navigate the treacherous waters. Under extreme duress, this means that the outburst can be violently cold and austere, even severe, resorting to cold, cutting language to intimidate the offending party. (words like stupid, incompetent, clumsy, etc. would be used--belittling words)
That's my take, as I think about things, bouncing off of the thought of "is it logical?"
