I regret causing confusion here. It turns out that this correlation was true on the initial small data set, but after gathering more data, the correlation went away. So the real lesson should be: "if you gather data on a lot of low-frequency events, some of them will display a spurious correlation, about which you can make up a story."

You and/or Google HR were also prominently quoted as saying, IIRC, that GPA, standardized test scores (and interview ratings?) had no observable correlation with job performance either. I always wrote that off as just range restriction/Berkson's paradox, but did those also go away?
