What really frustrates me is Lazy HBD. There are dozens of public use data sets waiting to be explored from a HBD perspective. Statistical packages can be downloaded for free. All sorts of HBDish questions can be addressed: Do 2nd generation Blacks do worse on cognitive tests than 3rd+ generation Blacks? Do mixed White and Asians outperform Whites? What is the standardized difference between first, second, and third generation Hispanics controlling for SES? Does color correlate with IQ in the Hispanic population? Does color correlate with crime in the Black population? But it seems that few are interested. I don’t get it.
First, people do have a tendency to rate their intelligence correctly--self-described intelligence is positively correlated with measured IQ--but the tendency is only moderate. Next, males are not more likely than females to inflate their smarts. By contrast, blacks are significantly more likely to--compared to whites. The other racial/ethnics groups do not differ from whites.
