For the past month I’ve been trying to type myself and managed narrow it down to those two. Tests give me the LSI-Ti result but I can’t be certain as ESI-Se is also extremely relatable. I don’t quite understand whether having rigid moral principles and not compromising them have to do with Ti or Fi. Going by Quadras or Reinin Dichtonomies didn’t work out since I don’t completely identify with either.

In MBTI I am ISTJ 1w9 6w5 3w4 sp/so if that matters. Most people would convert it to SLI but I’m definitely PolR-Ne. Also MBTI ISFJ has Fe which I most certainly lack.

So my question is what are the most obvious differences between them so I can finally come to a conclusion?

As for another minor question, would my 6 fix more likely to be phobic or counterphobic in that combination? I don’t seek out confrontations but refuse to back down when they happen.

Apologies if I posted this in the wrong section and thanks in advance!
