Elite political incivility is rising across democracies

The study analyzes 13.8 million tweets from parliamentarians in 26 democracies and finds that severe political incivility nearly doubled from about 2.7 % in 2017 to 5.8 % in 2022. Populist parties are the strongest predictor of incivility, especially when in opposition, while stronger liberal democracies are associated with lower levels of severe incivility. The increase is largely behavioral, with mainstream parties becoming more aggressive, leading to a narrowing gap between radical and mainstream parties’ uncivil rhetoric.

High prevalence of antagonizing rhetoric in trending topics on Twitter/X

The study introduces a computational method to distinguish between antagonizing and criticizing rhetoric in political discourse on Twitter/X. Analyzing over 17 million tweets from German trending topics, it finds that roughly one‑third contain antagonizing rhetoric, which is more prevalent in trending discussions than in general Twitter traffic. Right‑leaning users use antagonizing language more than left‑leaning users, and both forms of rhetoric are amplified within political camps, with certain parties—AfD and the Greens—emerging as primary antagonists.

LLM-Ideoplasticity: Measuring Ideological Plasticity in the Political Behavior of LLMs as a Context-Conditioned Distribution

arXiv:2606. 28335v1 Announce Type: cross Abstract: We argue, with systematic empirical evidence, that a large language model's political ideology is not a fixed point, but a conditional distribution $\mathbb{P}($position$\mid$context$)$ over a real political space.

Validating LLM-generated political networks with survey-reported partisan exposure

The study evaluates large language models (LLMs) that generate political networks by comparing them to survey-reported partisan exposure from the ANES 2020–2022 Social Media Study. It finds that while network structure and political assortativity vary across model configurations, many models either over‑separate Democratic and Republican egos or underestimate Republican exposure, leading to group‑specific errors in local partisan environments. These discrepancies persist even among networks with similar aggregate properties, indicating that aggregate metrics alone can mask important individual‑level inaccuracies.

Blaming Across the Aisle: Political Contrasting and Blame Attribution in the Danish Parliament

The study analyzes blame attribution in the Danish Parliament from 1997 to 2026 using a custom classifier, BlameBERT, and multilevel modeling. Results show a banana-shaped trend: blame fell until about 2016, then rose sharply from 2019 onward. Blame is consistently higher by opposition parties, especially among right-wing and ideologically extreme groups, indicating an ideologically asymmetric hardening of political discourse.

Unifying Models of Intergroup Hostility in Online Discourse

The paper examines how six foundational theories of intergroup hostility—boundary construction, threat construction, scapegoating, negative evaluation, dehumanization, and action orientation—manifest in online discourse. Using 2.86 million posts from TikTok, Truth Social, and Twitter/X during the 2024 U.S. presidential election, the authors model these mechanisms within a common empirical framework and find that boundary and threat construction anchor the system, with a regular temporal ordering of rhetorical strategies. The study maps theoretical frameworks onto real-world discourse, offering a clearer empirical basis for computational social science to model intergroup hostility beyond single-label detection.
