People who use Fi judge by whether something fits the values they hold inside. Even if others say something is good, they will not choose it if it does not fit their own standard.
Fi is a way of judging by whether something fits the values held inside. People who use Fi judge right and wrong by the values inside them, not by outside rules.
People who use Fi find this standard hard to put into words. When asked why they judged that way, they find it hard to answer, but that does not mean the standard is unclear. In fact, the standard rarely changes, so it lasts.
People who use Fi first check whether something fits the values inside them. They look at whether they can accept what they are about to choose, and if they cannot, they will not choose it even if the benefit is large.
It also understands other people's feelings through its own experience. When it has been through something similar, it understands deeply, and it tries not to speak carelessly about things it has not experienced.
It seems easygoing on the outside but suddenly says no at some point. It goes along with most things, but it will not agree to requests that go against its own standard.
Because it does not explain that standard, the people around it see this as fickleness. Making clear in advance what is fine and what is not reduces this misunderstanding.
People who use Fi are strong in work that takes long, steady effort before results appear, because they can keep going by their own standard even when no one else recognizes it.
It also suits work that requires understanding people deeply. It looks not at what someone says outwardly but at what that person is actually trying to protect.
They use different standards. People who use Fi take the values inside them as their standard, and people who use Fe take the state of the people they are with.
So they react differently when conflict arises. People who use Fi first look at whether they can accept it, and people who use Fe first look at how the people they are with will be affected. Both are feeling functions, but they keep their standard in opposite places.
When Fi is very strong, compromise is hard. If the person keeps doing things that go against their standard, they may seem to be coping on the outside, but inside they become very tired.
At a moderate level, they consider both their own standard and the situation. When Fi is weak, they follow outside standards, so decisions are easy, but later they are not sure what they actually wanted.
The strength of Fi is also shown separately in the assessment. Even within the same type, people with different Fi scores make very different choices.
