I think that most of the really successful traders are both very intelligent and very well educated. That's because in our culture, intelligent people seek more education, get scholarships, etc.
Another consideration here is that we all know that to succeed in trading, one needs discipline as well as intelligence. This relationship strengthens the argument that good traders are well educated (getting a good formal education takes a lot of discipline.)
On the other hand, lots of (average or mediocre?) traders come to trading out of a (conscious or subconscious) desire to gamble. That's where I would look to see more average intellect and lower educational achievement.
