The truth bearing of Fe dominant
Remember this about functions: If you lead by the dominant function, you are led by the inferior function.
ENFJs and ESFJs are driven by their Introverted Thinking (Ti), and they use Extraverted Feeling (Fe) as the means to express Ti. That makes them logically driven people. This is different from other Fe's of other types. They interact with the world via Fe based on their Ti laws and principles. They seek the truth, live by the truth, promote the truth. They can live so logically and objectively they're willing to ignore their own feelings and opinions. They see feedback from others are more objective (read more valuable).
We've always heard how Ti is like having this one single truth or theory of everything. Ti-domimants like to build and model their own, Fe-dominants promote it. Truth sets people free, the world is better off if we understand more about it. They can even be evangelical about that. Harmony is when everyone's unified by that one Ti truth—for everyone to agree on something and fall in line.
The typical descriptions of ENFJs and ESFJs are sensing other people's emotions. But again, Fe is just the means to promote Ti. Many of us picture them as social people pleasers when they’re actually ego managers enforcing logical rules and convincing others to follow them. So one way to reword that is typically ENFJs and ESFJs have learned to be good with people and emotions in order to find sensible ways to instill truth in people. Fe is the utility and creativity to inform emotional human beings.
A practical example is being a teacher teaching math in grade school. Arithmetic is irrefutable truth in the practical sense, and we're better off knowing about it. Some of us might *feel* discouraged when we don't get it, and the Fe-dominant teacher can help us sort our feelings around and help us better intake the information.
But it’s not like Fe-dominants figured everything out nor have the necessary knowledge to make themselves useful in the first place. They study. A lot. That’s what Ti Oppositional means—To proactively research and acquire knowledge for Fe to shape the world. The best teachers make the best students. Learn to follow before you lead. More than any other type, Fe-dominants put a lot of pressure on themselves to ensure they’re in the position of knowing what they’re doing. If they were insecure about one thing, it’d be losing that credibility. There’s motivation to go beyond competence, and be the embodiment of excellence.
Competence is meeting performance expectations, excellence is putting a face on it.
So that introduces many ways an Fe-dominant can be:
The more extraverted ones can get into more combative situations where people may not agree with their Ti. They'll try to hammer in and talk some logical sense into them.
The more introverted ones are rather private with what they believe in, they might see Ti as principles to live by on a personal level. And would only share their thoughts if those around are willing to listen.
The more anxious ones feel like they believe in something that people might disagree on and might get volatile about, so they keep it to themselves.
The more agreeable ones tend to operate safely with information that everyone already agrees with. Everyone likes humor, everyone likes music for example.
There are infinitely more, these are just what I can come with. Just remember that there's a catch with Ti, in that it's actually quite subjective. But ENFJs and ESFJs can get too caught up with it thinking it's objective and that people should look at it as such.
