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.

Does ideological congruence or perceived competence matter more for vote choice? @dieterstiers.bsky.social & @annkristinkolln.bsky.social argue both matter, but valence consistently outweighs spatial considerations. Read more: buff.ly/J3cy21u @polstudiesassoc.bsky.social #polsky #polsci
Abstract
Rational choice theories offer one of the major explanations for citizens’ voting behavior. The most prominent models within the rational choice framework – spatial and valence voting – share the same roots but differ in central aspects, emphasizing ideological congruence and competence evaluations, respectively. In this note, we provide a direct test of the models’ relative strength. Does a party’s issue congruence with a voter (spatial) or its effectiveness in handling important issues (valence) have a larger effect on vote choice? Our results from lab-like conditions using a novel conjoint experiment show strong evidence for both models, but valence evaluations consistently trump spatial considerations. These results have important implications for research on electoral behavior, party politics, and democratic representation.

Overall, the findings suggest that the electoral returns to valence communication depend on parties’ broader strategic and ideological positioning. More work on valence politics is coming soon!

Stefano Sangiovanni @stesangio.bsky.social · 07/08/2026
Once parties’ broader positioning is taken into account, the picture changes. Policy-based competence claims become more positively associated with polling support when parties blur their ideological positions, while character-based appeals become less effective.

Stefano Sangiovanni @stesangio.bsky.social · 07/08/2026
The main finding is simple: not all valence appeals work in the same way. Character-based appeals are consistently associated with more favourable polling dynamics during election campaigns.

Stefano Sangiovanni @stesangio.bsky.social · 07/08/2026
I examine this using campaign communication from the Comparative Campaign Dynamics Dataset (@marcdebus.bsky.social et al.) and daily polling data from 57 parties across 11 elections in 8 European countries. Rather than comparing parties, I focus on within-party polling dynamics during campaigns.

Which city/district councils have live streams of their meeting and can they serve as a data source for political scientists? Do politicians behave differently when they are on a live stream? Find out in the open access research note by Paul Reimers (in German) doi.org/10.1007/s11615-026-00672-8

Bridging the Gap? Liveübertragungen in Kreistagen und Stadträten als Datengrundlage für die politikwissenschaftliche Forschung - Politische Vierteljahresschrift
The scarcity of meeting minutes makes it difficult to analyze the working methods of local political bodies and the behavior of the actors involved. The increasing availability of livestreams and video recordings of district and city council meetings is helping to remedy this situation. Combined with technical innovations for extracting and processing large (multimodal) datasets, this availability enables new perspectives for local political research. However, for this wealth of data to be widely used, it must be generalizable to the broader population of local government bodies. Accordingly, questions arise regarding whether districts and cities that offer livestreams and recordings differ systematically from those that do not and whether these broadcasts induce shifts in local political debates.To this end, based on systematic research and a survey of district council members, this study describes the legal, political, and financial framework for introducing such recordings and examines the resulting influence on speakers’ behavior. Meeting recordings are available, particularly in large cities, but have so far been scarce in districts with low population density; furthermore, significant differences exist among the federal states. The survey indicates that adjustments to expanded public visibility of meetings are also occurring at the local level. Thus, the external validity of meeting recordings as a data source is not yet established, which should be taken into account during research design and case selection.
