well perhaps, being an N, i view everything as attempts to explain Da Big Truth and thus criticize accordingly.
i don't know for sure if they were actively trying to impress, or even if they were directed by a subconscious need to impress.
disregarding accuracy i willingly admit to having made assumptions. i think assumption is unavoidable but that is another matter.
what i disliked was not your explanation per se but the connection with some shallow self-reports from intuitives. again, assuming these are there to support your view. the self-reports are boring and poor to me because they are rather concrete despite attempting to describe the abstract. biased they are through the concrete cultural associations that still, to me, imply a desire to impress which distorts the validity of their accounts.
i may be overthinking N vs. S but most typology sources view cognitive functions as essentially distinct, i.e. specific neural processes, albeit unexplored. some of them view the functions as behavioral cathegories instead, but in any case it's a bit problematic to have a personality variable so easily equated with intelligence, don't you think? after all personality psychology strives to recognize variation as complementary and neutral.
that is actually a very good idea for a thread. this issue is pretty much the core of jungian typology imo.
