Conversely, here's the method of "arguing" that an IEI might use (using a huge sample size of Myself) if the goal isn't simply to win at all costs..
Involves more compromisation, responsiveness to clear logic, desire to de-escalate and promote the fact that it's not a conversation against but two people wishing to work together:
deliberately not getting emotionally heated and deliberately not taking offense at things, showing that they assumed the person didn't mean to attack them but rather just explain a point of view (regardless of it's true or not) and kind of be like, okay so what can we do.. take genuine interest in what the person is saying and trying to UNDERSTAND what they're saying and make it clear that they are trying to do so(showing genuine curiosity via Fe) and taking turns. the goal is to promote a shared point of view that this is a discussion. show zero malice. smile genuinely. (preferably not fake-genuinely lol) So that's how I'm good at de-escalating things.
I've come to realize it's quite Fe/Ti rather than Fi/Te. it is harder with Serious quadra because they don't seem responsive to "logic" or whatever. For example, when ILE and I argue, ideally, with Fe we maintain the fact and keep reassuring that we are on the same side and share goodwill throughout (with Serious, it's like they tell you it once and I know they mean it, but i always get scared and i need to always be reassured via outward emotional display, which Fi won't provide), with Ti we say exactly what we feel even if it's ugly, and we try to make sense of things together and work things through from there. With Fi/Te I feel like everything has to be so personal and illogical. my goal is to get it so we can really understand each other as well as possible.
i think i could get accused of rationalizing things too much, but with the right person, it is not viewed this way. for almost everyone except a couple of people, i would not be so emotionally invested into arguments and try to almost-100% resolve them, so I'll be fine with not being so invested in trying to understand each other and doing what i personally view as "superficially" resolving things-- it is resolved and we are happy, but i don't feel like we really understood each other as much as possible (probably because i feel that it's not possible just due to how we each see things differently) and really addressed the roots of the problem. i haven't come to feel closer to understanding them in the process, but simply resolved the issue itself and the relationship at this moment..
