Research indicates that the typical criminal has an IQ of around 90. Since the mean IQ of Hispanics is in the same range, I wondered if the deportation of criminals is not eugenic for the Hispanic population.
Using General Social Survey (GSS) data, I estimated mean IQ for Hispanics who have ever been arrested and those who haven't. I limited the sample to native-born Latinos since IQ tests in English are biased against people who don't speak English well (sample size = 92).
Arrestees have a mean IQ of 92.2. For non-arrestees, the mean is 92.9--not much higher.
