   Liberals tend to have higher IQs than their conservative siblings

   A new study from an excellent team of scientists at the U. of Minnesota   
   finds that higher IQ siblings tend to be more politically liberal than   
   their lower IQ brothers and sisters. And polygenic scores for IQ predict   
   liberalism even better than do IQ tests.   
      
   Since Thomas Bouchard’s famous 1990 Minnesota Twins study reuniting   
   identical twins largely raised apart, the University of Minnesota has been   
   a leader in hard-headed analyses of the effects of nature and nurture using   
   sibling, twin, and adoption studies along with the new polygenic scores.

   Here’s an important new article in the scientific journal Intelligence out   
   of Minnesota’s crack psychology department:   
      
       Predicting political beliefs with polygenic scores forcognitive   
   performance and educational attainment

       Abstract   
      
       Intelligence is correlated with a range of left-wing and liberal   
   political beliefs. This may suggest intelligence directly alters our   
   political views. Alternatively, the association may be confounded or   
   mediated by socioeconomic and environmental factors. We studied the effect   
   of intelligence within a sample of over 300 biological and adoptive   
   families, using both measured IQ and polygenic scores for cognitive   
   performance and educational attainment. We found both IQ and polygenic   
   scores significantly predicted all six of our political scales. Polygenic   
   scores predicted social liberalism and lower authoritarianism, within-   
   families. Intelligence was able to significantly predict social liberalism   
   and lower authoritarianism, within families, even after controlling for   
   socioeconomic variables. Our findings may provide the strongest causal   
   inference to date of intelligence directly affecting political beliefs.   
      
   Trust me when I say that that this study isn’t some conspiracy rigged up by   
   leftists to make conservatives look bad.
