Intelligence and conservative views on gender

Kirkegaard and I have written up a new paper on the relationship between political views and intelligence:

Literature on the association between political views and intelligence has largely focused on the linear relationship between the two variables, with nonlinear relationships between these two variables being rarely examined. The National Longitudinal Study of Youth (1979), a cohort of about 10,000 youth born between 1957 and 1963 who were administered the ASVAB in 1981, were used as a source of data. IQ and support for the Republican Party were related within Whites (r = .13, p < .001), Hispanics (r = .12, p < .001), and Blacks (r = -.073, p < .001). Within Blacks, IQ and support for the Republican Party were curvilinearly associated: support for the Republican Party was highest within highly intelligent and unintelligent Blacks (F = 18, p < .001). IQ and conservative gender attitudes negatively correlated within all races, however, this relationship did not hold in individuals with an IQ above 115, even within the large White subsample (r = -0.005, p = 0.85, n = 1060).

This was the 8 item survey on gender attitudes that was asked in 4 different waves and and one question that asked about people’s political party affiliation:

I combined the answers to each of the gender-related questions from all four waves into one general factor, which I named ‘conservative/traditional gender views’.
