So as I have laerned about the functions I have noticed some combinations pari very poorly together.
For me for instance:
A dominant Fe and my secondary Fi don't always agree and can rub each other the wrong way (even though I very much value the ENFJs and ESFJs I am around as they can be awesome both personally and organizationally-just not as very close friends normally. I make them twitch.)
Another example is when I am stressed I start using tertairy Te to control things. If I am around ENTPs and they start using thier tertiary Fe, profound disgreements can occur as I attempt to control and dominate and they become emotive to get out from under my attempts at control. My very worst fights w my Best Freind ENTP have come from this area and before the functions I could never figure out why.
So question: Have you come across combinations of functions that seem to be harder for you to work than others? Do certain combinations inherently clash?
