What started as a political science project with Slava Jankin and Hannah Béchara spiraled into its own paper, exploring how language shapes how we perceive distances & construe events. Excited to share the journey! #sciencerocks

👏Applause offers a revealing lens on party competition! In a recent article @wepsocial.bsky.social (w/@jocmuel.bsky.social+@pluggedchris.bsky.social), we study how applause reflects party and coalition unity, ideological agreement, political exclusion, issue ownership, and the electoral cycle! (1/6)
Cover page of the article: "The sound of party competition: how applausereflects unity, disagreement, and the electoralcycle in parliamentsAndreas Küpfera , Jochen Müllerb and Christian Steckeraatechnical university of Darmstadt, Darmstadt, Germany; buniversität Greifswald, Greifswald,GermanyABSTRACTThis article studies how applause reflects the dynamics of party competitionduring parliamentary debates. While legislative scholars often emphasise theselection of speakers and content of debates, spontaneous reactions from fel-low MPs remain understudied. Analysing 750,000 instances of applause in thedebates of the German Bundestag (1976–2020), it was found that applausepatterns, although largely spontaneous and immediate by nature, systemati-cally reflect incentives from party competition such as signalling party andcoalition unity, ideological (dis)agreement, and ostracising specific parties.Applause also indicates issue emphasis, especially near elections. The findingssuggest that applause can serve as a nuanced and abundant indicator in thestudy of party competition, complementing more static measures derived frommanifestos and expert judgements. By analysing applause patterns over fourdecades, this study opens new avenues to explore nonverbal reactions asmarkers of party competition in other parliaments."

Today @10 in Pacific Rim 2: our framework for assessing LLM output. a) separates general vs. domain-specific similarity b) handles existing classifiers c) accounts for probabilistic DGP d) model-independent & efficient

I'm at #APSA25! On Saturday at 2 pm (Panel "Seeing is Believing: Innovations and Applications in Image Data Analysis"), I'll present a new project with @chrisguarnold.bsky.social, Oliver Rittmann, and @smtorres.bsky.social in which we quantitatively measure media slant based on news article images.

Heading to #EPSA2025 in Madrid next week! I will be part of a paper asking:

"How Useful is Your LLM Output?"

It is the first from a project on simulating political negotiations w/ LLMs.
DM if you are around---tea, coffee, or confusion matrices?
