hm. i came out as ENFJ, so i'll go back through and give you my thoughts on the questions i think i probably scored "wrong" on.
You are most likely an ENFJ. Okay, this is your result. Your functions are listed below. [i reordered them for ease of comparison]
Fe:14
Ne:13
Fi:12
Se:11
Ni:10
Si:8
Ti: 7
Te: 6
i think i responded to a lot of Fe questions because the statements are essentially just F, and don't split between Fe and Fi.
When others around me are unhappy, I usually become unhappy.
i would guess this is a Fe question, but it's very true for me as well. this might be skewed for me in particular more than other Fi users because my Fi is aux, and therefore secondary to external perception. negative environments are generally displeasing to me because i'm very impacted by my surroundings.
anyway, regardless of that, i still don't think this statement is totally clear between Fi and Fe. a Fi dom/aux would probably still be unhappy when others are unhappy because they have an ethical problem with whatever's making the others unhappy - war, or bullying, or something else negative like that.
maybe you could say something like "i have a very good understanding of social currents."
I put a lot of effort into making others happy and creating a sense of harmony in my social circle.
same thing with Fe and Fi again... both are fundamentally interested in people's well-being. i think the difference comes in that if there's a problem between two people, a Fi user would rather them just confront it aloud and get to the bottom of it instead of trying to preserve a harmony (that seems artificial and therefore probably harmful to Fi) by having them wait until they're in private. maybe you could say something like "i believe that social harmony is always more beneficial than harmful"?
I tend to have a good awareness of how others are feeling and feel pulled to attend to their emotional needs.
is this Fe or Fi? i think that'd apply to both. "emotional needs" is probably more Fi - Fi being intrapersonal, Fe being interpersonal.
i think i scored high on Se because both Se and Ne have an affinity for new, colorful, fast paced experiences.
both allow you to be good at quickly adapting and thrive off more and more information. i think it might be helpful to differentiate between enjoying and being skilled at. people with high Ne might enjoy new sensory stuff but it's because of the associated inflow of new ideas - no way we're as good at comprehending or dealing with it on a sensory level as people with high Se.
I enjoy new and varied sensory experiences such as visiting new and exotic places.
maybe something like "i am good at navigating new sensory experiences" instead?
I find a lot of joy in engaging in exciting physical activities.
same thing here... i love exciting physical activities but that doesn't make me any good at them, especially not the first time around. maybe you could say something like "i am good at adapting to new physical activities" instead?
i think that brainstorming is somewhat misrepresented when talking about Ne.
not just in your test. in general.
I tend to go with most ideas that I come up with through brainstorming.
not that i don't appreciate others' contributions, but i could talk to a brick wall and still come up with new ideas - for me, the act of talking it out is more about the way that speech (or writing) makes you frame your ideas in a different way, so that you see new combinations of ideas, that then lead to new ideas. and then talking with people can be useful in that it double-checks for practicality, which Ne enjoys disregarding, lol...
maybe you could have something along the lines of "i am very good at expanding on and reformulating others' ideas" instead - something that emphasizes external sources for iNtuition but doesn't make it sound like you
need people to idea-generate.
I frequently bounce ideas off people to see what can be thought of.
similar thing. this would seem to imply that the other person plays a role in idea generation too - other people are useful for bouncing ideas off of not because they add more ideas, but because they reign my ideas in with realistic parameters.
ok i think that's all i have to offer

i like the idea of the test and i hope what i've said can help refine it accurately.
