We investigate the effects of populist messages that (a) stress the centrality of “ordinary” people, (b) shift blame to the “corrupt” elites, or (c) combine people centrality and antielitist cues on 3 dimensions of populist attitudes: anti-elitism, homogeneous people, and popular sovereignty. We conducted an extensive 15-country experiment in which we manipulated populist communication as social identity frames (N = 7,271). Multilevel analyses demonstrate that messages stressing the centrality of the ordinary people activate all dimensions of populist attitudes. In contrast, anti-elite messages activate anti-elitism attitudes only for those individuals with lower levels of education and extreme positions on the ideological left–right spectrum. Our findings suggest that populist political communication plays a key role in activating populist attitudes across Europe.

民粹主义身份框架对整个欧洲民粹主义态度的影响：来自 15 个国家的比较实验的证据

我们调查了民粹主义信息的影响，这些信息 (a) 强调“普通”人的中心地位，(b) 将责任推给“腐败”精英，或 (c) 在民粹主义态度的 3 个维度上结合民粹主义和反精英主义线索：反-精英主义、同质化的人民和人民主权。我们进行了一项广泛的 15 个国家/地区的实验，其中我们将民粹主义交流作为社会身份框架（N  = 7,271）。多层次分析表明，强调普通民众中心地位的信息激活了民粹主义态度的各个方面。相比之下，反精英信息只会对那些教育水平较低且意识形态左派和右派极端立场的人产生反精英主义态度。我们的研究结果表明，民粹主义政治传播在激活整个欧洲的民粹主义态度方面发挥着关键作用。
