> Using IQ is effectively illegal[2] in the US, so you'll have to find a test that acts as a good proxy.

You've posted this before and been called out on it. Please stop spreading misinformation.

There is nothing special about IQ tests specifically. Any proxy test will have exactly the same legal ramifications. As long as you can show that the results of that test are relevant to job performance, it is fine. Whether it is labeled an "IQ test" is irrelevant.

Put plainly, the callout and yourself are wrong. To muddy the waters about this may put small companies at risk.

I've spoken with an lawyer about this. There is case law directly concerning IQ tests.

The bar for acceptance to prove the use of IQ in hiring in a discrimination case is unattainable by most software companies. Hence, it is effectively illegal.

NB: I would desperately love to use IQ tests in the US myself. I want to be on your side and use IQ tests, but wouldn't risk my supper for it.

I didn't intend to imply that IQ tests are okay (although the test I suggested is in fact what you have to prove). I'm actually concerned by the suggestion that IQ proxy tests are any different. They are bound by exactly the same requirements.
