ABSTRACT Two twin studies are used to explore genetic influence on political discussion. Results from both studies demonstrate latent genetic traits account for, on average, 40.63% of variance in traditional and online political talk, discussion with agreement and disagreement, and political conflict avoidance. Taken together, the findings suggest a heritable genetic mechanism may partly explain why individuals vary across multiple dimensions of political discussion and differentially experience discussion effects. Implications for the political discussion effects literature and for reconceptualizing the etiology of political discussion are discussed.

政治讨论的遗传影响：两项双胞胎研究的结果

摘要 两项双胞胎研究用于探讨遗传对政治讨论的影响。这两项研究的结果表明，在传统和在线政治谈话、同意和不同意的讨论以及避免政治冲突中，潜在的遗传特征平均占方差的 40.63%。综上所述，研究结果表明，一种可遗传的遗传机制可能部分解释了为什么个体在政治讨论的多个维度上存在差异，并且对讨论效果的体验也不同。讨论了政治讨论影响文献和重新概念化政治讨论的病因的含义。
