本研究分析德国2015-2025年的推文与议会演讲，发现极右翼AfD进入议会后，德国各政党转向基于直觉的修辞，右翼精英的EMI得分最低，极右翼可见性与精英真理态度转变相关。
AI 中文摘要
错误信息的传播被广泛视为对民主审议的威胁，但随着民粹主义者崛起，政治精英对真理的修辞承诺如何转变却鲜为人知。我们分析2015至2025年间德国政治精英的450万条推文及59170次议会演讲，采用经验证的分布式词典表示法衡量基于证据和基于直觉的修辞。在两个领域中，基于直觉的语言愈发突出，右翼倾向者始终呈现最低的证据减直觉（EMI）得分。2017年极右翼德国选择党（AfD）进入议会，与整个议会EMI急剧下降同步，而推特上则呈现更渐进的下降。这些发现记录了多党制欧洲民主国家中，极右翼可见性与精英话语中真理态度转变之间的关联。
英文摘要
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.
