I didn't say cultural bias was an issue, you're twisting my words. And the people I know who vouch for the effectiveness of test prep classes don't even teach them anymore, they taught them mostly as a summer jobs or jobs out of college before they found more of a career path job. They have no reason to vouch for the effectiveness of the classes, they are speaking about personal experience. And you honestly don't think the classes help at all? Seeing sample questions, taking sample tests, and learning strategies to handle questions you don't know. You might as well say structured practice doesn't help. And sure you could say "why don't the kids from less affluent families practice just as much?" but if your parent doesn't know how the game is played the sixteen year old kid still isn't as prepared as the kid who has affluent parents. And the scores aren't going to reflect ability as much as they reflect whether you come from a household that prepares you for standardized tests.

The demographic information collected for the test is a proxy for culture, since we really don't have any idea. We just detected if individual test items were gotten wrong substantially more often for any individual demographic categories. In the end it really doesn't matter why people got it wrong, just that statistically it's a strong sign it's a bad question. Yes, the tests help. But they just help you reach your maximum potential. You're not hacking the test, you're hacking yourself. You can get basic prep courses for not much money. Yes some people cannot afford that, but that is a problem with secondary education that test prep even exists. There is no way you can make a test that doesn't discriminate against people that don't get enough sleep or show up hung over or the person didn't figure out the basics of taking standardized tests through primary and secondary education.
