Populism in the Plenary - Populist Rhetoric and its Effects on Debates, Legislators and Voters

是什么让政治言论成为民粹主义？民粹主义言论对议会辩论、立法者和选民有什么影响？我采用定量研究方法，以衡量民粹主义言论在1999年至2017年欧洲议会议会辩论中的存在，调查民粹主义言论如何影响议会辩论以及立法者的行为，评估民粹主义言论对选民的影响以及如何改变这些影响。更准确地说，我将衡量民粹主义的修辞手段的监督分类，这是通过众包培训，调查的影响，民粹主义的修辞精英行为相结合的花束不同的定量文本分析工具，如字典和主题模型，并评估其对选民的影响在两个调查实验。尽管这本身就是一种贡献，但在议会辩论中制定一个可靠的民粹主义言论衡量标准非常重要，因为它是系统研究民粹主义言论如何影响议会和民主话语以及选民的先决条件，而这反过来又对理解民粹主义如何改变欧洲政治至关重要。

: What makes political rhetoric populist? And, what are the effects of populist rhetoric on parliamentary debates, legislators and voters? I adopt a quantitative research approach in order to measure the presence of populist rhetoric in parliamentary debates of the European Parliament from 1999 to 2017, to investigate how populist rhetoric affects parliamentary debates as well as the behaviour of legislators, to assess the effects that populist rhetoric has on voters and how these effects can be changed. More precisely, I will measure populist rhetoric by the means of a supervised classifier which is trained through crowdsourcing, investigate the effects of populist rhetoric on elite behaviour by combining a bouquet of different tools of quantitative text analysis such as dictionaries and topic models, and assess its effects on voters in two survey experiments. Despite being a contribution on its own, developing a reliable measure for populist rhetoric in parliamentary debates is important because it is a prerequisite for systematically investigating how populist rhetoric affects parliamentary and democratic discourse as well as voters which in turn is vital for understanding how populism transforms European politics.
