The University of Minnesota Twin Cities study published in the journal Intelligence found correlation between higher IQ scores and left-wing/liberal political beliefs[1][2]. The study examined over 300 families using both IQ tests and genetic polygenic scores to predict political orientation within families sharing the same upbringing[2]. Lead researcher Tobias Edwards stated: "We find both IQ and genetic indicators of intelligence can help predict which of two siblings tends to be more liberal. These are siblings with the same upbringing, who are raised under the same roof"[2]. The paper's results indicated that "polygenic scores predicted social liberalism and lower authoritarianism, within families"[2]. However, the researchers included substantial caveats about interpretation. Edwards explicitly cautioned: "The way our intelligence affects our beliefs is likely dependent upon our environment and culture" and noted that "there have been extraordinarily intelligent people on both the left and right, from Oppenheimer to von Neumann. These and many more examples show that there is no reason why we must presume one ideology to be more intelligent than another, even if smart people seem more likely to align with one belief or another"[2]. Regarding the education component of the claim, available sources do not provide data comparing educational attainment levels by political affiliation. Research on US IQ generally indicates that environmental factors—income, parental education, nutrition, and healthcare access—are strong predictors of cognitive test scores[3], suggesting that correlations with political beliefs may reflect these broader socioeconomic variables rather than ideological differences themselves.
