Data: Are lighter-skinned Hispanics smarter than those with a darker tone?

The General Social Survey (GSS) had interviewers rate the skin tone of respondents from 1 (lightest) to 10 (darkest). This can serve as a rough proxy of European ancestry. GSS also gave them a ten-question vocabulary quiz which is highly correlated with verbal IQ.  I limited the analysis to Hispanics born in this country who self-identified as white (N= 185).

The correlation between IQ and skin tone is -.28, which indicates a medium-strength association between European ancestry and higher intelligence.
