I would argue that judgement and intelligence are highly correlated. Ref: "hold my beer and watch this" videos on youtube. :)
To a point. It's been my experience that as the intelligent quotient increases past a certain point, the judgement quotient (to coin a term) decreases, especially with regard to other people.
I'd prefer someone 1 standard deviation above the mean with the capability of judging other's character and capabilities than someone three standard deviations above the mean without those qualities.
So, yes, there needs to be a minimum level of intelligence (not average), but the greater the judgement, the better.
Only tangentially related to this is the account I've read of
Earnest Shackleton. The author seems to think Shackleton was randomly choosing people for the expedition, for oddball reasons, but in the failed South Pole expedition, the group held together perfectly with only 2 (out of 56) who broke down under the strain.
He picked 56 people out of a total of 5,000 applications and only failed in his judgement of character twice. THAT is the kind of judgement I would like. Clearly he was highly intelligent, but it is his judgement I prefer.
