>We proposed and tested mediation models in which lower cognitive ability predicts greater prejudice, an effect mediated through the endorsement of right-wing ideologies (social conservatism, right-wing authoritarianism) and low levels of contact with out-groups. In an analysis of two large-scale, nationally representative United Kingdom data sets (N = 15,874), we found that lower general intelligence (g) in childhood predicts greater racism in adulthood, and this effect was largely mediated via conservative ideology

>Even though past studies show that women are more liberal than men, and blacks are more liberal than whites, the effect of childhood intelligence on adult political ideology is twice as large as the effect of either sex or race. So it appears that, as the Hypothesis predicts, more intelligent individuals are more likely to espouse the value of liberalism than less intelligent individuals, possibly because liberalism is evolutionarily novel and conservatism is evolutionarily familiar.
>liberals would be more flexible and reliant on data, proof, and analytic reasoning, and conservatives are more inflexible (prefer stability), emotion-driven, and connect themselves intimately with their ideas, making those beliefs a crucial part of their identity (we see this in more high-empathy-expressing individuals). This fits in with the whole “family values” platform of the conservative party, and also why we see more religious folks that identify as conservatives, and more skeptics, agnostics, and atheists that are liberal.
Conservatives would be less likely to assign value primarily using the scientific method.
