Steve Hsu looked at this: people scoring less than 600 on the math SAT were very unlikely to manage a B or better average as physics majors. There was an effective threshold.

I once looked at some sample questions on a exam for promotion to Captain in the NYPD. I go most of them right, enough to pass - invoking principles like " don't play practical jokes with a corpse, no matter how tempting".

But many cops just can't pass it, even after several tries. Same for the Sergeants' exam.

And, are you a good cop Mr Cochran? Point is is doing well in these tests in any way important for being a good Sergeant or Captain?

Cops have close-to-average IQs, but usually above 90. Would a cop with a higher IQ do better, on average? Probably: it's true for almost every job.
