德国政客在极右翼崛起后更倾向直觉化表达，影响公共讨论可信度。
German parties shifted towards intuition-based rhetoric after the far right's parliamentary breakthrough
- 用分布式词典量化政治话语中的理性与直觉表达比例。
- 2017年极右翼政党进入议会后，全议院理性表达显著下降。
- 适用于研究政治传播、舆论演变及民主制度韧性的人群。
虚假信息的蔓延被普遍视为对民主讨论的威胁，但政治精英在民粹势力崛起时如何调整对真相的修辞态度仍不清晰。本研究分析了2015至2025年间德国政治精英发布的450万条推文和59,170篇议会演讲，采用经验证的分布式词典方法测量证据型与直觉型语言。在两个领域中，直觉型语言均变得更突出，右翼阵营的证据减直觉（EMI）评分始终最低。2017年极右翼政党“另类选择党”（AfD）进入议会后，整个议会的EMI值出现急剧下滑，而推特上的变化则更为缓慢。研究揭示了极右翼政治可见性与精英话语中真相观念转变之间的关联，呈现了一种多党制欧洲民主国家中的趋势。
原文摘要 · Abstract (English)
The spread of misinformation is widely perceived as a threat to democratic deliberation, yet how political elites' rhetorical commitments to truth shift alongside the rise of populist actors remains poorly understood. Analysing 4.5 million tweets and 59,170 parliamentary speeches by German political elites between 2015 and 2025, we measure evidence-based and intuition-based rhetoric using a validated distributed dictionary representation. Across both arenas, intuition-based language has become more prominent, and right-leaning actors consistently exhibit the lowest Evidence Minus Intuition (EMI) scores. The parliamentary entry of the extreme-right Alternative for Germany (AfD) in 2017 coincides with sharp downward shifts in EMI across the broader chamber, while a more gradual decline is observed on Twitter. These findings document an association between far-right visibility and a changing approach to truth in elite discourse in a multiparty European democracy.
