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.

用认知能力和教育程度的多基因分数预测政治信仰
智力与一系列左翼和自由主义政治信仰相关。这可能表明智力会直接改变我们的政治观点。或者,这种关联可能受到社会经济和环境因素的干扰或介导。我们在 300 多个亲生家庭和收养家庭的样本中研究了智力的影响,使用了测量的智商和多基因分数来衡量认知表现和教育程度。我们发现,智商和多基因分数都能显著预测所有六个政治量表。在家庭内部,多基因分数可预测社会自由主义和较低的专制主义。即使在控制了社会经济变量后,智力仍能显著预测家庭内部的社会自由主义和较低的专制主义。我们的研究结果可能是迄今为止关于智力直接影响政治信仰的最有力的因果推论。
