This sounds pretty self-serving to me, I must say. Wouldn't it be possible that there is no pattern whatsoever, and an intuitive sees one that isn't there, whereas a sensor would in fact be more accurate just determining the accuracy/validity of the information? Wouldn't that be more "intelligent" than a mental process that was flawed to begin with? I don't think that your assertion that intuition correlates with intelligence holds water.
you're only saying that because you think you're an S. i think you're an ENFP.
and of course N functions are correlated to intelligence. if you use no N functions, you never broaden your context or try to see other viewpoints. Ss that are smart are smart because they use N functions.
if you're facing a problem and you can't come up with a solution, you gotta use N functions. otherwise you'll beat your head against a wall forever. EVERYONE uses N functions. Ns just use them more often than Ss.
(i'm gonna get attacked for this)
