Fourth: this leaves a severely fragmented party system. By my count 🇩🇰 now has the 2nd most fragmented parliament in Europe, surpassed only by 🇧🇪. Traditionally, parties have delivered mostly stable governance in spite of fragmentation. But we are in uncharted territory. (4/4)

Third: the mainstream left loses votes to the radical right. A familiar pattern reemerged: the single biggest voter movement between blocs was Social Democrats losing voters to the Danish People's Party. (Based on estimates from the final YouGov poll). (3/4)

Second: overall, a terrible night for mainstream parties. The four traditional "prime ministerial" mainstream parties had their worst collective result ever, dipping below 50 pct. for the first time. (2/4)

FOUR GRAPHS ABOUT 🇩🇰'S GENERAL ELECTION My read of the election in four graphs. First: big urban-rural divide. The two big mainstream parties, Social Democrats and Liberals, are now mainly rural/suburban, with niche parties dominating in cities. (1/4) #polisky

🪙Do politicians signal partisan conflict through what they say? ➡️ Using Danish parliamentary debates, @mathiasoestergaard.bsky.social & @fghjorth.bsky.social show that vocal pitch signals partisan polarization, revealing the strategic use of nonverbal cues cambridge.org/core/journal... #FirstView

If you work on legislative politics, polarization, or computational methods, we hope this provides a new toolkit and motivates more work on nonverbal signals in democratic politics. Full article (open access) here: www.cambridge.org/core/journal... Thanks for reading this far! 🙏 11/11

The paper concludes by outlining implications for representation, elite behavior, and experimental design. If emotional arousal is both perceivable and strategic, then public reactions—and misperceptions—may depend on vocal features that standard text-based analyses cannot detect. 10/11

Substantively, the results imply that elites communicate partisan conflict even when their words remain civil or non-polarized. Nonverbal cues allow legislators to signal conflict along dimensions not easily observed in text. 9/11

Methodologically, our findings highlight the value of audio as data for political science. Text alone cannot capture pitch, intensity, or prosody—yet these features encode meaningful political information. Multimodal approaches can enrich research on polarization and legislative behavior. 8/11

This distinguishes spontaneous emotional display from strategic communication. In parliamentary settings, vocal style appears to be *deliberately deployed* to influence audiences and coalition partners, not merely an uncontrolled affective reaction. 7/11

We then ask: are these signals strategic? Two results suggest yes. • Legislators exhibit greater arousal in high-profile debates with substantial media attention. • They signal more conflict toward parties with > bargaining leverage—i.e., parties that could shape alternative governments. 6/11

Importantly, these patterns persist *conditional on verbal content*. Even when sentiment, emotionality, and topic structure are held constant, pitch carries distinct information about partisan conflict. Nonverbal communication adds an independent dimension to elite polarization. 5/11

We also show that nonverbal conflict signals correspond closely to policy disagreement. When two parties vote differently on a bill, legislators’ pitch rises significantly in speeches addressing the opposing party. This is a robust, dyad-level pattern. 4/11

Our core finding: nonverbal arousal systematically tracks partisan polarization. Legislators speak with higher pitch when addressing out-bloc parties than in-bloc parties. This holds even after accounting for sentiment, rhetoric, and topic controls. 3/11

Using >20 years of Danish parliamentary audio (≈380,000 speeches), we develop a measure of emotional arousal based on within-speaker deviations in vocal pitch. Decades of psycholinguistics show that pitch rises when speakers are more emotionally activated. 2/11

Political communication research overwhelmingly relies on text. But parliamentary speech is multimodal! In our new @psrm.bsky.social article, Mathias Rask and I show that legislators also signal partisan conflict nonverbally— through changes in vocal pitch during floor speeches. 🧵 1/11 #polisky

In *the annotated sample alone*, these proportions correspond to ~1500 published survey experimental papers yearly, rising sharply. I'm no stranger to survey experiments myself, but seems a bit much.

Why has women's representation in parliament been lagging? Can it be that party elites have penalized women candidates? Come find out tomorrow at "Primaries and Candidate Selection" at 8.00 am in West 215. @fghjorth.bsky.social @fkjoeller.bsky.social @annalund.bsky.social @apsa.bsky.social

I highlight two main implications: first, the rhetorical cost of governing adds to our understanding of the constraints faced by governing parties (and the advantages oppositions enjoy). 9/10

Do voters prefer simple rhetoric? Yes. In a preregistered survey experiment (N ≈ 4k), citizens preferred the exact same policy stated simply over complex wording by 0.34 pts on a 0-10 scale. 8/10

Instead, it's likely about agenda constraints. Topic model evidence shows ministers pivot toward technocratic & crisis issues (e.g., EU treaties, COVID-19) and away from easy ideological staples (taxes, immigration) → govt. agendas are harder to talk about simply. 7/10

It is not about formal speech requirements. To show this, I consider high profile opening/closing debates where ministers aren’t forced to read bills. Same simplicity gap. 6/10

🔄 Once politicians leave cabinet, simplicity bounces back. No evidence of a permanent drift—this is office-specific, not aging or learning. 5/10

To provide evidence, I collect 1.5 million speech snippets from Denmark’s parliament (1997-2022) & link them to every MP’s career path. I use two measures of simplicity, validated with survey assessments. 3/10

Electoral costs of governing are well established. But what about non-electoral costs? I highlight 'the rhetorical cost of governing': simply put, holding government office constrains politicians' ability to craft simple, effective messages. 2/10

So what happens to volunteer led sites like stackoverflow now? Do the companies that ate them make and release the labels they generate for new languages? Do we just hope and pray LLMs fill the gap? Something real has been lost.
