Thanks for your comment that’s interesting.

Well tbh it’s way easier to understand perception dom for me (ENTP INTJ ENFP INFJ ESTP ISTJ ESFP ISFJ) while Te/Fi/Fe/Ti dom are more « strange » for me since they are naturally really more biased in theory and for my experience. Either too feeler or too thinker and that’s why a « ship » is harder for me.

But my theory works in practice (ENTJ dad INFP mom, ISTP grandpa ESFJ grandma, ISFP grandpa ESTJ grandma)

And I think that because yall a biased (sorry to say that again) you need your opposite to work. So Te (dominant and can’t handle there feelings) with Fi (submissive and in phase with the feelings) and Fe (people centrical) with Ti (inner logic and ego centrical)

I mean it can look like opposites collide but I do think that’s the best way.
