A test that is multiple choice can easily be biased. I will give a brief example, though the bias won’t necessarily be “anti-black.”
I am putting together a math question for the SAT. The math question, rather than just saying, "33% of 525 is ____ " asks the question using a baseball hypothetical, in which a player has 525 at bats, and hits .330, resulting in how many hits? Now, for those who are at all aware of baseball and baseball statistics, this question is not difficult to answer. But if you are not aware of baseball, if you pay little attention to the game, and the statistics that accompany it, you will be at a disadvantage in trying to determine what exactly the question is asking.
This is a very simple example of what is a very complex science: reducing or removing test bias from standardized tests. One way to tell if a test is biased is to look at the results of the test over time and see if they produce unexpectedly low scores for certain groups of test takers, when other potential score-lowering factors are accounted for. Indeed, one of the ways of proving that discrimination is occurring against a particular group is to use statistics showing otherwise unexplainable low results for a protected class, such as “blacks.”
So, the issue in the New Haven case is this: the city offers its firefighters a test, the results of which will be used to create a promotion list. The list will follow the “rule of three,” that is, that promotions have to be offered first to candidates who score in the top three rankings of the results. When the test is scored, it turns out that no blacks, and IIRC only one Hispanic, fall into the top three ranks. In addition, overall, the scores of “black” and Hispanic candidates are significantly lower as a group than those of the non-minority candidates; relatively few of the minority groups “passed” the test (which makes them eligible for promotion at all, once the top three ranks are promoted or decline promotion). The City of New Haven finds these results alarming; they worry that this is evidence that the test unintentionally discriminated against the “black”, and to a lesser degree Hispanic, candidates. Fearful that a lawsuit under Title VII would follow, they decided to annul the results and try again with a different test. As a result, certain non-minority candidates sue under Title VII, asserting that the city has engaged in intentional discrimination against the non-minority candidates.
As for whether or not it is acceptable to discriminate in favor of non-“white” people as a government, the answer is yes, it is acceptable, but how it can be done is not exactly settled law. Starting with the Bakke case in 1978, up through the University of Michigan cases of a couple years ago, the Supreme Court has said that race may be a factor used to determine the admittance of candidates to schools and the like. In addition, other cases have established that affirmative action programs are an acceptable method of remedying the impact upon society of past discrimination against “blacks.” The legal analysis for this follows the following algorithm: remedying the effects of anti-former slave discrimination is an issue of vital importance to government, and as long as the method is very closely tailored to help accomplish that goal, it will pass the otherwise strict scrutiny to which we subject such discriminatory acts.
The law in this area is VERY fluid. Stay tuned for developments.
