The present research directly replicates past work suggesting that metadehumanization, the perception that another group dehumanizes your own group, erodes Americans’ support for democratic norms. In the days surrounding the 2020 US Presidential Election, American political partisans perceived that their political opponents dehumanized them more than was actually the case. Partisans’ exaggerated metadehumanization inspired reciprocal dehumanization of the other side, which in turn predicted their support for subverting democratic norms to hurt the opposing party. Along with replicating past work demonstrating metadehumanization's corrosive effect on democratic integrity, we also contribute novel insights into this process. We found the most politically engaged partisans held the most exaggerated, and therefore most inaccurate, levels of metadehumanization. Moreover, despite the socially progressive and egalitarian outlook traditionally associated with liberalism, the most liberal Democrats actually expressed the greatest dehumanization of Republicans. This suggests that political ideology can at times be as much an expression of social identity as a reflection of deliberative policy considerations, and demonstrates the need to develop more constructive outlets for social identity maintenance.

在 2020 年总统选举期间，元非人性化侵蚀了民主规范

目前的研究直接复制了过去的工作，表明元非人性化，认为另一个群体将你自己的群体非人化的看法削弱了美国人对民主规范的支持。在 2020 年美国总统大选前后的日子里，美国政治党派人士认为，他们的政治对手对他们的非人化程度超过了实际情况。游击队夸大的元非人性化激发了对方的相互非人性化，这反过来又预示着他们支持颠覆民主规范来伤害对方。除了复制过去证明元非人性化对民主完整性的腐蚀作用的工作外，我们还为这一过程提供了新的见解。我们发现政治参与度最高的游击队员持有最夸张、因此也是最不准确的非人性化程度。而且，尽管传统上与自由主义相关的社会进步和平等主义观点，最自由的民主党人实际上表达了对共和党人最大的非人性化。这表明政治意识形态有时可以作为社会认同的一种表达，也可以作为审议政策考虑的反映，并表明有必要为社会认同的维护发展更具建设性的渠道。
