None of these will work because the reason for population differences is genetic and not just opportunity.
At every level, across thousands of school systems and tens of thousands of tests, even when opportunity is normalized, the rank order of various populations–particularly ones based on gender and traditional racial categories–does not change simply because opportunity is equalized or supposed bias is removed.
The New Haven case is typical, but it’s only a newsworthy example. The broad ordinary experience never makes the news.
Women can’t compete on any kind of screening test devised for the NFL or PGA.
White western european men aren’t ever going to be equally represented in the NBA just by providing them better opportunity and helping them not be so lazy in their work ethic for developing basketball skills.
Blacks are never going to be on par with asians on their SATs even if their household is superiorly educated and richer, and their schooling system superior in comparison with the asian peer group.
The differences in potential among our population groups is genetic, and until we come to grips with that, we’ll continue to have laws based on an incorrect premise: that given equal opportunity, all groups will perform equally. That’s nonsense and no one has ever been able to show it.
8 years on after identical educational background opportunity, 1st-year Post-Med School licensing exams show the same broad disparity between and the same rank order between blacks and whites that was present at admission to college (and admission to med school).
Any hiring screen that requires quantitative measures for physical or mental capacity will always show a difference among populations because those differences–at an average level for race- and gender- based populations, at least–are genetic and therefore immutable.
