Call for Proposals: Data Collection for Replication+Novel Political Science Survey Experiments Alexander Coppock and Mary McGrath January 27, 2026 We invite proposals for a survey experiment replication+novel design competition. Se- lected replication+novel design survey experiments will be conducted on large samples of American respondents, quota sampled to match U.S. Census margins and filtered for quality and attention by the survey sample provider Rep Data (repdata.com). Each proposal consists of two parts: (1) a replication study of an existing, previously published survey experiment, and (2) a novel experimental design on a topic of the authors’ choosing. The replication studies and reanalyses of the existing studies will be combined into a meta-paper to be co-authored by all authors of accepted proposals along with the princi- pal investigators (Coppock and McGrath). As a condition for acceptance, authors commit to sharing the data and producing a write-up of the findings from their novel design for submission to a scholarly journal, and public posting of a working paper pre-publication.

🎺 Call for proposals 🎺

1️⃣ replicate an existing experiment
2️⃣ run a novel experiment

on repdata.com

3️⃣ coauthor with Mary McGrath and me to meta-analyze the replications and existing studies

After years in academia, I’m exploring data science and research roles in industry.

I'm a quant. social scientist (PhD Yale ’24, NYU) focused on causal inference, experiments, and large-scale data.

Feel free to get in touch or share; all leads appreciated. dwstommes@gmail.com

Yes, I know I am late. Yes, I know the world is on fire. Sorry!

Looking for 1-2 papers (and maybe one more discussant) to put together an #APSA2026 panel proposal on recent methodological developments in surveys/experiments (can go either way). Feel free to reach out!

Shameless plug. We made a similar distinction a while ago: gustavodiaz.org/files/resear...

I appreciate the emphasis on the importance of intellectual origins and how they map to different goals. Sometimes people talk past each other because their training emphasizes one or the other more.

An Audit of Social Science Survey Experiments Abstract. Survey experiments have become a popular methodology for causal inference across the social sciences. We study the efficacy of survey experiment

Needed - larger samples, more realism about (the lack of) heterogeneous treatment effects:
-"less than a third of proposed hypotheses were supported... the largest predictor of positive exp. results was sample size"
-"moderation hypotheses were rarely significant"

🏆APSA's Experimental Research Section Best Paper Award🏆
Did you present an experiment at APSA2026? Submit your conference paper for the Experimental Research Section's best paper award by April 15, 2026. @sumitra.bsky.social @talbotmandrews.bsky.social and I are excited to read your work!

Currently in FirstView: In “Balancing Precision and Retention in Experimental Design,” @gustavodiaz.org and Erin Rossiter study how experimental design choices can increase precision when estimating treatment effects. Specifically, they examine block-randomized and pre-post designs.

Just over one week to go before the September 16 deadline.

Excited to review the applications and engage with folks’ work!

Check out this fascinating paper by my colleagues Erin Rossiter and Jeff Harden. Such a cool design and interesting findings. Plus, Taylor!

“Balancing Precision and Retention in Experimental Design.” Political Analysis, 2025, 1–10. https://doi.org/10.1017/pan.2025.10008 Gustavo Diaz and Erin Rossiter In experimental social science, precise treatment effect estimation is of utmost importance, and researchers can make design choices to increase precision. Specifically, block-randomized and pre-post designs are promoted as effective means to increase precision. However, implementing these designs requires pre-treatment covariates, and collecting this information may decrease sample sizes, which in and of itself harms precision. Therefore, despite the literature’s recommendation to use block-randomized and pre-post designs, it remains unclear when to expect these designs to increase precision in applied settings. We use real-world data to demonstrate a counterintuitive result: precision gains from block-randomized or pre-post designs can withstand significant sample loss that may arise during implementation. Our findings underscore the importance of incorporating researchers’ practical concerns into existing experimental design advice.

Hey, I'm on the Casual Inference podcast this week!

I've been a massive fan of @lucystats.bsky.social and @epiellie.bsky.social since Episode 1 of Casual Inference. Talking to great experts (and conversationalists!) like them was a ton of fun.

Thanks so much for the invitation!

Diaz, Gustavo, Virginia Oliveros, Rebecca Weitz-Shapiro, and Matthew S. Winters. “Ignoring Women’s Performance: A Survey Experiment on Policy Implementation in Argentina.” British Journal of Political Science 55 (2025): e54. https://doi.org/10.1017/S0007123424000668. Abstract How does a politician’s gender shape citizen responses to performance in office? Much of the existing literature suggests that voters hold higher expectations of women politicians and are more likely to punish them for malfeasance. An alternative perspective suggests that voters view men politicians as more agentic and are, therefore, more responsive to their performance, whether good or bad. Using an online survey experiment in Argentina, we randomly assign respondents to information that the distribution of a government food programme in a hypothetical city is biased or unbiased, and we also randomly assign the gender of the mayor. We find that respondents are more responsive to performance information – both positive and negative – about men mayors. We find little evidence that respondents hold different expectations of malfeasance by men versus women politicians. These results contribute to our understanding of how citizens process performance information in a context with few women politicians.

Put me in, coach!

Thanks and sorry for the delay! It's a mix of topics ranging from causal inference to concept formation to fieldwork. There is already one discussant so you would split papers. If you email me at the address on my website I can tell you more.

Polisky! Still need one more!

Polisky! I'm looking for volunters for chair/discussant for a panel on fieldwork and qualitative methods for the next MPSA conference. Ping or email me if interested👀
