Based on my time spent working with a man who tested as an ISFP (as told to me by him), I would say that he had interest in concrete, real-world aesthetics that was more physical than mental. Also, he had an interest in the politics of personal relationships that I didn’t really understand, inasmuch as my preferences in terms of interpersonal engagement would have left me with zero political capital in the game as he saw it. I should also mention, “the game” is my language, because I have difficulty thinking about it in terms of anything other than an idea; he didn’t think of it that way — to him, it was a dynamic process.
On the other hand, I would begin to speak of something in an abstracted, conceptual way and I would see him roll his eyes and he would then tell me he had neither capacity or patience for that kind of talk.
But in some ways, we were very much alike.
cheers,
