Intelligence testing is a human created concept. There are all manner of cultural biases encoded in it. Intelligence is more than just being good at sums which is what your math SAT example seems to suggest.
Jeopardy champions are hardly a representative group. They're a self-selecting group by definition : those who chose to go on a quiz show. Maybe men show a bias towards showing off on TV or are better at remembering random facts. Your example doesn't control for any of those.
