You would be appalled to learn that the courts have ruled repeatedly that police departments can utilize iq quota limits, so that people with higher IQ aren't let on the force. I learned about this from hearing about it, like "my friend tried to join and they wouldn't let him" and I'd ask if their friend was smart and they'd say he was very smart, and once you hear about 2-3 people who didn't get in and all were remarkably intelligent, you start putting things together.
