Actually I think it'd have the opposite effect. Certain people are more qualified to recognize corruption and self-serving in gov't and vote it out than others. Generally, that would be high IQ people, but some high IQ people don't give a shit, so they'd be out. You could have a lower than average IQ and still pass the 'informed' test. You basically just have to demonstrate some political savvy. Not sure how that would work in practice though or what the test would look like.
