about candidates for law enforcement being rejected for scoring too high on entrance tests. They claimed people who were too smart were easily bored by the job and tended to quit after a couple years (after the community spent a ton of money to train them). In some ways, a sound business decision and an attempt to maximize taxpayer value.

Of course all that reads as "we only hire stupid people to be cops."

Also doesn't help that some of the people society expects the most from (law enforcement and educators come to mind) just aren't paid very well.
