>But say passing the test was a requirement to vote, wouldn't the people who want to vote naturally proceed with studying for and taking the test, while those who don't want to won't be bothered since overcoming the obstacle is even greater than overcoming the resistance of mailing in a form or going to an actual booth? The problem is that any such test with answers could be inherently biased against some groups. 'Do I feel like going to vote today' is not biased in such a way as the person taking the test is the creator of the test itself. Imagine if there was a test to vote, but every person created their own test, answered their own test, and then scored their own test (and the test didn't have to make sense to anyone, including the person who created/took/graded it).
