Before Google became a huge success, it tried to select for the smartest people, in so far as it was legally possible to do. It then became a huge success.
Today, Google’s chief human resources officer tells us selecting for smart does not work, so Google does not do it any more. (Hat tip, Lion of the Blogosphere)
What do you think is more likely: That selecting for smart does not work, or that it gives politically incorrect results?
This looks like the same phenomenon as elite educational institutions furtively or openly blowing off the LSAT, and contenting themselves with an intake that is low on the LSAT. Google says smarts are not useful, colleges are finding the results of LSAT inconvenient.
