IQ does correlate with passing professional tests.
But I’d posit that gays are positively correlated with obsessive behavior and precision in completing tasks—which would correlate with your description.
My point was simply to debunk the idea that gays would need AA to become train engineers.
Passing the test doesn't always correlate to doing the job reliably.
But if the end result is that an unqualified person was made the driver of this train, isn’t that the exact same result as AA?
