The fact that they seem very prevalent in security clearance is quite alarming, I suspect security clearance does not assume to be attempting to trick gullible applicants.

If they were just a gimmick I don't think they would be used as much as they are. Clearly there is some validity to them. How much is the question. I'd be willing to bet they are right more often than they are wrong.
