&gt; I also have a sneaking suspicion that the raw statistical analysis of such a test from the U.S. in 1975 would show a lot of intrinsic racial, gender, political, and age biases.<p>Of course. Public institutions in America are a total joke now because they&#x27;re riddled with patronage posts and affirmative action hires. Any test that actually works is going to be &quot;racist&quot; and &quot;sexist.&quot;
