A great many pixels have bee spilt over Ron Unz's March cover story in The American Conservative, "Hispanic." The critiques that appeared at AltRight and VDARE can be found here, here, and here -- and Unz's response to them, here. If you'd like to follow the debate play-by-play, the best place to turn is this exhaustive catalogue on the Conservative Heritage Times's blog.
And just today, Jason Richwine has written another blog on the subject, this time over at AEI, and he includes this startling new revelation:
Though this is only one of many contentious issues, Unz suggested that a 2006 report from the Public Policy Institute of California (PPIC) could help resolve it. The PPIC report uses incarceration data from California’s government that Unz says could be among the most reliable available. The report gives an HDW of 1.48, which Unz claims as a victory. Once we control for age, he says, the HDW comes down to just about his 1.1 estimate.
But Unz missed something important in the report. The 1.48 number is already fully controlled for age. I exchanged emails with one of the PPIC report’s coauthors to confirm this fact.
