If we're going to have a discussion about ending the requirement for a college degree or other seemingly arbitrary job requirements we have to understand why companies seek those things. The answer is that companies want to hire smart workers. It's fine to suggest that the degree requirement is wasteful, but I don't think we can expect employers to stop using that metric if we can't offer a better one. IQ is already something employers are looking for, even if they use coded language like "smart" or "problem solvers." Let's at least make it explicitly legal for them to ask for it.

I'm not going to suggest that there's absolutely no bias in the IQ tests themselves, but we've come a long way with them, and they're certainly going to be less biased than the average human who is hiring. Your IQ has no race or gender.
