I think my friend is ISFJ.
It's obvious that she is a feeler. When we met 2 years ago, that was the most obvious thing about her. I think that xxFJs usually appear to be obviously feelery, and we are sure she is a 2w1 (when me and another friend of hers read the description, we laughed so hard). She has a very strong E1 wing in her. I mean, she could be a 9 ..............BUT SHE IS A 2, DAWG.
She cares SO MUCH about the opinions people have about her. Like, it's so cute and sad and dramatic at the same time; she'll come home depressed/in tears when she would come home from work sometimes. Life becomes hard for her if the people around her aren't warm to her the way she'd like. She had issues with being bullied in the past, so she is super sensitive. Rejection is super hard for her. She is definitely a warm person and wants to see the world turn into a warmer, caring place where people are there for each other. She feels really really really really strong feelings for those who are mistreated but she isn't "fiery" about her values like I feel an ExFJ would do so (according to the Myers Briggs book, it's the feeler who is EXTROVERTED that champions their values, not the feeler that is introverted. Again, this is how a mistype happens if you rely on shallow descriptions you get from psychology classes or high school guidance counselor).
...I mean, I guess she is fiery. However, she doesn't champion her values for the sake of it... it's only when it's really really needed. So that is why I think her Fe is second
She used to write poetry and other things. She is an awesome writer. Like, no joke... sometimes I think she was born in the wrong century because you practically never see poetry so well done these days. She actually won lots of awards for her work. It is something that really mattered to her (it probably still does), but she doesn't promote her writing. It's not that kind of writing that you can put in a stereotypical blog these days. She doesn't do it to feel unique or anything, she writes because she simply finds it beautiful. She HARDLY ever shares it with anyone; I think I just got really lucky that day. She really isn't into writing so she can share it and inspire people. It's something that really is PURELY for herself. She really just likes the cool ways you can say things. But she hides it from everyone ever because it's close to her heart and it would be a sensitive thing if she had people looking/judging her work. Instead, she puts A LOT of her focus on volunteer work (like she wouldn't go to a graduate school that wouldn't give her the time to be of service in some way). She volunteered at children's hospitals and organizes fundraisers for children in other countries to go to school. She is a scientist (I think this is due to a strong influence of her mom, who wanted her to be a scientist). And she is good at it. In college, I felt like she over-worked herself. She hates not doing something because she'll feel bad. Of course, she apologizes too much for being a "bad friend". Like, if I call her and she doesn't pick up (because she is sleeping or something) you can sense it in her voice that she feels so horrible. She is always over-exerting herself for her friends (but she doesn't resent it; it's what she feels she has to do ...same thing with being a scientist.... she doesn't resent the pressure... in fact, she does very well conforming to it). On some level, she likes being a scientist. She likes tinkering with things and seeing what works. And she has a really great understanding of the concepts/details to know when something won't work. But at the same time, this is how she gains acceptance from the world.
I want to stress how the poetry aspect about ISFJs have this sensitive poetic side to them, but the popular opinion about ISFJs does not reflect this. This not because MBTI is wrong ...becuase this side of them really IS hidden. This is where Fi and Si can get confused because both functions are pretty secretive like that. Si doms don't parade their feelings for all to see and neither do Fi doms. I think this is the same for INFJs. I am looking through the book and the Ni in INFJs barely gets touched.
When there exists no capacity for artistic expression, all impressions sink into the inner depths, whence they hold consciousness under a spell, removing any possibility it might have had of mastering the fascinating impression by means of conscious expression. Relatively speaking, this type has only archaic possibilities of expression for the disposal of his impressions; thought and feeling are relatively unconscious, and, in so far as they have a certain consciousness, they only serve in the necessary, banal, every-day expressions. Hence as conscious functions, they are wholly unfitted to give any adequate rendering of the subjective perceptions. This type, therefore, is uncommonly inaccessible to an objective understanding and he fares no better in the understanding of himself.
This is a quote taken from Jung. Si is best expressed artistically, but if it cannot do that... then thought/and feeling (which are best understood consciously), take over and that gives the ISFJ the "every day expressions" we normally see in them. Their Si can be largely hidden. So, in my friend, her expressions (Fe/Ti) come out in her volunteer work, being a Christian and stuff like that).
I want to use this last point to also stress that is the ESFJ/ENFJ user who has the desire to impact people/parade their values, according to Myers Briggs. They are usually more expressive/have the desire to express. Their thoughts/feelings take shape when they can express. Both ESFJs and ENFJs) are described as idealistic and seek ways to express their idealism. I think that people confuse even Ne/Fi or Fi/Ne for extroverted feeling often because people rely on tests that have been adapted from Myers Briggs to use in the corporate world... where they don't care for such a distinction. So they get rid of that when they make their tests for high schoolers and stuff. But the actual MBTI makes it clear that it is the Fe user that cares for self-expression more than the INFP or ISFP. IxFPs appear to be "judgy" ...looking for ways that match their internal idealism. IxFP and ExFJ probably have the same level of internal idealism in them... but the Fi user doesn't show their feeling (hence why a lot of them mistype other introverted types, such as INTP, if they rely on high school style personality tests instead of the actual MBTI book). When I was in high school, the psych test my guidance counselor gave me said I was INFP and the description was like "they are the inspirering/champions" or something like that. At that time, my extroverted feeling was really strong, so that is why I got such a result. So I think that those who think they are INFP due to high school style testing are a mixture of any of the xxFJ types, including the extroverts.

This is how her Fe/Ti come out (in the banal, everyday expression).
