Looking forward to kicking off the LSE's brand-new Political Methodology seminar! I will present new work with @tarasenkogeorgy.bsky.social and Andrey Tkachenko on detecting batch-generated responses in survey data delivered by third-party vendors. Get in touch for the Zoom link or the draft.

Researchers who outsource survey fieldwork to third-party vendors cede oversight over the collection process. We present evidence that this practice is vulnerable to AI-generated responses within the vendor's pipeline. Analyzing an online survey of Russian residents in 2026, we detect a sharp discontinuity in data quality as the fieldwork deadline approached. Several distinct indicators, spanning open-ended text patterns, completion times, and closed-ended response distributions, shift together during the affected period. The patterns are consistent with coordinated batch generation rather than scattered respondent-level AI use.  While the current literature on AI contamination in surveys focuses on respondent-side threats, our case highlights a risk that data providers within an outsourced data collection pipeline may use AI to fabricate responses. We discuss conditions that amplify supply-side risks of AI responses and propose practical safeguards for researchers who outsource fieldwork.

@christinajuen.bsky.social & I are very happy to see our first publication of our @dfg.de project published in Party Politics. GLMP provides a new dataset for studying local party politics in 🇩🇪: 2,307 manifestos from 306 political actors in 248 municipalities (1989-2024) doi.org/10.1177/1354...

I am very happy to share our new article, published in the @ejprjournal.bsky.social co-authored with Prof Andrea Ceron! This work looks at how parties use the rhetoric of responsibility in their electoral manifestos. #PoliticalScience #PartyPolitics #PoliticalCommunication #Manifestos #LLMs #NLP

🚨 PUBLICATION ALERT 🚨 I am extremely excited that the First View of my new article "Strongmen, Populism, and Soccer: Comparing Silvio Berlusconi, Viktor Orbán, and Donald Trump" is now available. It was quite an ordeal to get it past reviewer 2, but I made it with help of special issue editors.

What makes citizens engage with politicians on social media? Our new study shows that negativity, particularly personal attacks and incivility, gets attention, but not necessarily approval. Citizens comment and share more on such posts, but they don’t necessarily like them. ➡️ doi.org/10.1057/s412...

Engaging citizens? The role of negativity and incivility on politicians’ social media - Acta Politica

Studies show that negative social media posts by politicians generate higher levels of citizen engagement, yet not all forms of negativity have the same effects, nor do they operate uniformly across c...
