Would you support a basic aptitude test in order to vote?

This study here tested a citizen's own ability to pass their country's own naturalisation test with Australia ranking very high and UK very low

It's debatable, to put it no higher, whether these citizenship tests measure anything of importance. They certainly don't measure civic responsiblity or political awareness and I think it would be bizarre to base voting rights on them.

What the Australian test mainly measures is command of English — most people who fail the test do so because they misunderstand the questions or they cannot express the answers clearly. Most people who sit the test already have permanent resident status and have been living in Australia for years. There are countless reports of people failing the test despite a considerable history of living, working, paying taxes, raising a family, community engagement, volunteering, etc in Australia.

The failure rate for the UK citizenship test is much higher because it's a much tougher test. This has nothing to do with measuring civic virtue or responsibility; it's simply an aspect of the "hostile environment" policy of making settling in the UK as difficult and unpleasant as possible. The questions have nothing to do with acceptable standards of citizenship; they're largely trivia designed to catch out as many people as possible. People have been asked things like "Who made the film Four Weddings and a Funeral?", "Name the patron saints of the countries of the UK, and the feast day of each of them" and "Is the UK a member of OPEC?".

Only if the 'aptitude test' can be contrived in the intervening weeks of an election by the sitting government. Seems democratic to me. 😁

Most other countries don't have knowledge, literacy or information tests for voters. Those that do are generally assumed to be engaged in thinly-disguised racial or other discrimination — e.g. the literacy tests that, up until the 1960s, were widely used in some US states to disenfranchise black citizens.

It's a form about where your grandad was born if you qualify for citizenship on the basis of descent.

But no country has a literacy or knowledge for those who qualify for citizenship by descent. The countries which have tests like that use them in cases of citizenship by naturalisation.

I think everyone should be allowed to vote but there should be a weighting factor to each vote based on a standardised IQ test.

I think it's desperately unfair that a stupid person's vote counts for the same as my one.
