You have to expound more on your "they are creative therefore they are not S" argument.
It's easy. Intuition is abstract, conceptual thinking, otherwise known as an imagination. Planning a heist requires N thinking.
What is the difference between being someone and acting like someone? You can't really read her mind, so you can only define her type via her actions.
By functioning as one type, but exhibiting a pattern of behavior most commonly associated with another type. Type isn't a measure of behavior but rather cognitive processing, so one can
work as one type (that being the type one is), but behave like another. I have an INTJ friend who exhibits the quirky, spontaneous humor of an ENTP for example.
Again, you are saying he behaves like an SFJ most of the time, except for the one time when he behaved like an INTJ, which makes him an INTJ?
That doesn't make sense to me.
No. I'm saying he
is an INTJ because ISFJs are not ruthless, meticulous strategists. And that isn't the only time -- The way he rescued River showed plenty of Ni Te, hence my reference to having caught the movie halfway. he also showed himself rather INTJ in Jaynestown, though not to the extent he did in Ariel. He is relentlessly polite and nice (and yes unwilling to kill people, though he does it if he has to -- again, not F), thereby exhibiting ISFJ behavior, but he is a definite INTJ.
Book was a devout preacher who died saying "I don't care what you believe, just believe in something". Quite an act to keep for an INTJ (even when he is about to die).
It's possible he was INFJ altogether, yes. It's also possible that he grew into the role over time, but I still suspect INTJ. The following two exchanges spring to mind:
Book: [
to Mal] If you take sexual advantage of her, you're going to burn in a very special level of hell. A level they reserve for child molesters and people who talk at the theater.
Zoe: Preacher, don't the Bible have some pretty specific things to say about killin'?
Book: Quite specific. It is, however, somewhat fuzzier on the subject of kneecaps.
On Inara being INFP: She shows herself to be a J on numerous occasions, particularly in Objects in Space, with her meticulously planned-out and structured list of accommodations. She's also rather decisive, one to take action herself rather than wait for events to come to her
