Abstract We examined the association between intelligence, party identification, and political orientations using genetically informative data gathered from German twins and their families (n = 9553 individuals including 1524 adolescent and young-adult twin pairs). The results indicated that supporters of the Pirate Party and the Green Party had levels of intelligence that were significantly higher than those of other party identifiers, with the exception of individuals who preferred the Free Democrats. These findings were remarkably similar to results based on British research participants that were reported in a previous study. We also observed a significant, albeit modest, negative correlation between intelligence and political conservatism, and our data indicated that this correlation could be accounted for by common genetic influences on those two variables. The findings of the study were interpreted in light of competing theories on the nature of the relationship between intelligence, party identification, and political orientations.

情报、政党认同和政治取向之间关联的模式和来源

摘要 我们使用从德国双胞胎及其家庭（n = 9553 个人，包括 1524 对青少年和年轻成人双胞胎）收集的遗传信息数据检查了智力、政党认同和政治取向之间的关联。结果表明，海盗党和绿党的支持者的智力水平显着高于其他党派标识符，但偏爱自由民主党的个人除外。这些发现与之前一项研究中报告的基于英国研究参与者的结果非常相似。我们还观察到智力和政治保守主义之间存在显着的，尽管适度的负相关，我们的数据表明，这种相关性可以通过对这两个变量的共同遗传影响来解释。根据关于智力、政党认同和政治取向之间关系性质的竞争理论，对研究结果进行了解释。
