They missed the fact that job ads that were listed as jobs for women and jobs for men, or even jobs for whites and jobs for blacks. And somehow didn't see a fairly startling salary gap between these sets of ads. Because of tests. Testing, of course, measures skills white men happen to be very good at, spatial reasoning and verbal logic. This is nonsense.
Firefighters take tests for promotion.
And there are certainly objective facts that one would want all firefighters to know. No city government in its right mind would hire a fire chief who got the best test scores but who dithered when decisions had to be made. And if a police force is made up of white guys commuting in from the suburbs to arrest black kids in the ghetto, it isn't a police force at all. It's an army of occupation. Don't think the black kids don't understand that.
