jesus, they have a hard time counting normal votes. how the fuck they gonna pull off that slight an adjustment?

But really, the problem with intelligence testing isn't that the factoring of intelligence is itself inherently evil, it's that intelligence is pretty hard to quantify and you couldn't trust the people who make the tests, so it would be to easy to politicize. Here in the states, incoming administration could so something like add the question "Global warming is a hoax y/n" with a "No" answer shooting down your score. Then bam, it becomes a test of political purity and we get into some weird territory.

A good example of how this has worked in real life comes from the South, where the literacy tests for voting used back in the Jim Crow days would involve asking the testee a vague question, with the answer's rightness or wrongness being determined by the tester. Made it easy as shit for the tester to make personally biased decisions on who can and cannot vote, which they used to turn away black voters.
