赞成票？反对票？没有投票？理解Reddit上反应机制与政治话语之间的关系
Upvotes? Downvotes? No Votes? Understanding the relationship between reaction mechanisms and political discourse on Reddit
摘要：
很大一部分政治话语发生在社交媒体平台上。政策制定者和研究人员试图了解社交媒体设计在塑造全球政治话语质量方面的作用。在过去的几十年里，政治话语理论的研究已经产生了不同类型的突出的政治修辞，如审议，公民，或蛊惑人心的话语的鲜明特征。这项研究调查了社交媒体反应机制（即，通过对政治话语理论进行深入的概念分析，研究用户讨论中的政治修辞（upvotes，downvotes）和政治修辞。首先，我们分析了2010年至2018年间Reddit上55个政治子论坛的1.55亿条用户评论，以探讨用户的政治讨论风格是否与审议，公民和煽动性话语的基本组成部分一致。其次，我们进行了一个定量研究，结合验证性因素分析和差异模型的差异，以探讨不同的反应机制方案（例如，只有赞成票，赞成票和反对票，没有反应机制）对应于或多或少具有审议、公民或煽动性话语特征的政治用户讨论。我们生产三种主要的外卖。首先，尽管是“政治修辞的理想结构”，我们发现政治话语理论在很大程度上描述了Reddit上的政治讨论。第二，我们发现，在子论坛中的讨论，只有赞成票，或赞成票和反对票都与用户话语，是更深思熟虑和公民。第三，社交媒体上的讨论在没有任何反应机制的subreddits中最具煽动性。这些发现为正在进行的关于社交媒体界面设计与用户之间相互尊重的政治讨论之间关系的政策讨论提供了宝贵的贡献。
英文摘要：
A significant share of political discourse occurs online on social media platforms. Policymakers and researchers try to understand the role of social media design in shaping the quality of political discourse around the globe. In the past decades, scholarship on political discourse theory has produced distinct characteristics of different types of prominent political rhetoric such as deliberative, civic, or demagogic discourse. This study investigates the relationship between social media reaction mechanisms (i.e., upvotes, downvotes) and political rhetoric in user discussions by engaging in an in-depth conceptual analysis of political discourse theory. First, we analyze 155 million user comments in 55 political subforums on Reddit between 2010 and 2018 to explore whether users' style of political discussion aligns with the essential components of deliberative, civic, and demagogic discourse. Second, we perform a quantitative study that combines confirmatory factor analysis with difference in differences models to explore whether different reaction mechanism schemes (e.g., upvotes only, upvotes and downvotes, no reaction mechanisms) correspond with political user discussion that is more or less characteristic of deliberative, civic, or demagogic discourse. We produce three main takeaways. First, despite being "ideal constructs of political rhetoric," we find that political discourse theories describe political discussions on Reddit to a large extent. Second, we find that discussions in subforums with only upvotes, or both up- and downvotes are associated with user discourse that is more deliberate and civic. Third, social media discussions are most demagogic in subreddits with no reaction mechanisms at all. These findings offer valuable contributions for ongoing policy discussions on the relationship between social media interface design and respectful political discussion among users.
