With that logic, I would be an INFP.INFPs are extremely imaginative and often out of it because we kind of live in our own worlds. ISFPs are not often out of it at all because they observe the world they're already in. As an INFP, I often feel i was meant to live in a fairy tale. ISFPs love the world around them and don't act for it to be different or try to imagine it in a different way that it is. INFPs are both curious and shy, so even being introverted they often will ask loads of questions. From the outside, INFPs and ISFPs appear very similar, both looking off into the distance quite a bit (at least from my experience). It's the thought process that will differentiate. ISFPs look at something and think about that one thing, and the beauty of it. INFPs appear to be looking at the same thing, but really that object is simply a trigger to other thoughts. These thoughts are often something completely out of this world. With feelings, ISFPs are easily hurt and they show it, but INFPs get hurt too just as easily, and they will quite often bottle it up and not let you know how they really feel. Both are creative, but the ISFPs creativeness comes from putting together what is already there, whereas the mind of an INFP produces things that can only exist in fairy tales and imaginations as mindblowing as theirs.
There are separate tests for just S/N. Some of them aren't too good but they have all helped me figure out some of the characters I write about. You can just google sensing vs intuition test, and a bunch of them come up. Based on what you have said so far, I think you're an ISFP. ISFPs are probably the most creative of the S-types anyway. I think you are because you are trying to figure out every detail at which you are one or the other. S-types do that. N's just want the big pictureI am not intuitive because people tell me I am not. Lmao.
If you read a description of S vs N
I do not resonate strongly with either.
I see two major differences in the way we interact with the world:
1) ISFPs are more willing to expose themselves to the world. By this I mean they are more prone to share emotions, more prone to live in the moment, they often seem more in touch with social conventions. This is because their second-strongest function is Se, Extraverted Sensing, or engaging in the present moment. This contrasts with INFPs' Ne, Extraverted Intuition, which is closer to seeing all the possibilities present in the world around us. This does not involve actually doing anything about our ideas! So ISFPs are more engaged with reality, I find, and generally have more friends than INFPs.
2) ISFPs have this tendency to become dependent on stronger personalities. I've seen this in almost every ISFP friend I've ever had, and it's super sad when the stronger personality is a shitty person who bosses them around and such. But going back to the dependency thing, I think it's just because ISFPs really, really want to be loved in the present moment (Fi + Se). By "tagging along," almost, with a person with a strong personality, I think this gives them more confidence to express themselves and be unafraid that people will dislike them, because everyone likes their close friend. I often see ISFPs playing a sort of "sidekick" role. As an INFP I have this more abstract view of it, like I want people to love me of course, but meh, that doesn't always have to happen right now, it WILL happen, somewhere and in some place, and here are a million possibilities in my mind of how it could happen.
