Even if you think that IQ tests are unscientific mumbo-jumbo, it's amazing to learn that some US police departments don't, and furthermore, that they defended their legal right to exclude potential officers because they tested too high.
From a 1999 NYT article:
In a ruling made public on Tuesday, Judge Peter C. Dorsey of the United States District Court in New Haven agreed that the plaintiff, Robert Jordan, was denied an opportunity to interview for a police job because of his high test scores. But he said that that did not mean Mr. Jordan was a victim of discrimination.
