Another alternative might be to do this random test online or at designated centres before each election. A lot of people I am sure would fail it first time, then have to actually look into the issues before casting their vote.I said at the time of eVoting that a quick 10 random question multiple choice quiz at ballot time - covering history and economics, civics, etc. would be a great way to weight votes. Score 10 out of 10 and get a full vote, score 5 out of 10 and effectively half your vote gets eliminated. 0 out of 10 and you still get to vote, it just doesn't get counted.
