New from Hainmueller and Laitin on the causal effects of becoming a citizen on wages. Short story: the observational ests overstate the premium relative to the experimental ests. Authors conclude "observational averages should not be used as causal forecasts for policy" doi.org/10.1073/pnas...

When oh when will polling outfits stop asking "more/less likely" questions? No way does this promise make 27% of the country *much less likely* to vote R, No way does this promise make a different 11% of the country *much more likely* to vote R!

The latest from YouGov: Does Trump's $5,000 promise make you more/less likely to vote R: Less +11 Would Trump keep this promise: Pro/definitely not +44 Would you be better off if Dems/Reps won in November: Dems +8 Everyone knows Trump is a liar. yougov.com/en-us/daily-...

Applications are open for EuroWEPS Berlin.👇There is also some change in the EuroWEPS organising committee. @pavisuri.bsky.social is taking a step back, while @aalrababah.bsky.social & @ewirsching.bsky.social are joining starting with this edition. A big thank you to Pavi & welcome to Ala and Elisa!

Anselm Hager@anselmhager.bsky.social · 2mo ago

EuroWEPS 14 is here! We'll meet in Berlin @wzb.bsky.social and discuss designs/papers focusing on causal inference. No presentations, just constructive discussions. Early career scholars especially welcome to apply! Deadline is Sept 11.

Northwestern poli sci is hiring in quant methods! I'm not on the committee, but I AM excited to welcome new junior colleagues. We're also hiring in IR -- separate search, same amazing department (and university!)

Northwestern is hiring in quant methods (assistant level, tenure track) Please repost and share with those you think would be good candidates, thank you! polisci.northwestern.edu/about/facult... #psjobs #psjminfo #poliscijobs

Assistant Professor of Quantitative Political Methodology (Tenure-Track)
The Department of Political Science at Northwestern University invites applications for a full-time position in Quantitative Political Methodology at the rank of Assistant Professor, tenure-track, to begin Fall 2027. We emphasize methodology with a strongly applied perspective: successful candidates will maintain an active, independent research program that includes methodological contributions in their own right, while also teaching quantitative research methods courses at the undergraduate and graduate levels and applying those methods to substantive questions in their area of expertise. We are especially interested in candidates whose work bridges data-driven/computational approaches with design-based inference, though we welcome applicants making cutting-edge contributions in either of these traditions or in other areas of political methodology. Successful candidates' substantive research agendas may be in any area of political science or may cross boundaries; as with all Northwestern faculty, successful candidates will be expected to provide service to the department, the university, and the profession.

Just an enormous difference in Russian support for the war when comparing direct question estimates with experiments from list experiments. Also, peep those CIs! sensitivity bias has to be HUGE (which it apparently is in this case) to be detected with Direct - List

Every wave after that splits. Direct support holds at ~75%. Indirect support drops to 44–58%. The gap runs from 16 to 30 percentage points.

I'm thrilled to share that my dissertation has been selected as the co-winner of the Best Dissertation Award from the APSA Women, Gender, and Politics Section. Many thanks to the award committee, and to mentors and colleagues who offered support along the way!

I really hope that Sociology reforms. My main work is reanalyzing other scholars' experiments in service of meta-analysis. It's only possible because transparency is embraced so thoroughly by our political science community. Most exps are posted; i'm getting ~80% when I email for the rest.

John Holbein@johnholbein1.bsky.social · 4mo ago

Only 9.9% of top Sociology articles from 2019-2024 provided replication packages. And ≈ half of those with replication packages could not be verified due to missing or incomplete materials. www.econstor.eu/bitstream/10...

🚨NEW PUBLICATION🚨 in Science Advances. We meta-reanalyze 100 conjoint experiments to assess which immigrants citizens prefer around the world. Our evidence reinforces existing findings, identifies novel insights, and provides a basis for future research 1/n www.science.org/doi/10.1126/...

Which immigrants do citizens prefer? A meta-reanalysis of 100 conjoint experiments

Meta-reanalysis of 100 conjoint experiments reveals patterns of similarity and variation in public immigration preferences worldwide.

He talked about description as well, including the specific recommendation to avoid associational language, simply because it has become so ambiguous (so not "is SES associated with Y" but rather: do people of different SES differ on average in Y).>

Climate change impacts are here, but public support for action remains polarized. Which climate messages move people? In a ~13,500-person megastudy, we tested 10 of the most-cited messages. Six increased pro-environmental attitudes in the U.S.—but only by 1–4 percentage points. 🧵

Once again asking people not to post about poll results without links to the surveys, and not to repost anything that cites poll results without links to the surveys. This is not (primarily) about credit, it's a data credibility check.

Friends, you've been submitting great proposals for this project and we're now coming up to capacity. We're closing proposals on April 15th; please send yours in!

Alex Coppock@aecoppock.bsky.social · 9mo ago

🎺 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 4️⃣ publish your study details: alexandercoppock.com/replication_... applications open Feb 1 please repost!

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.

Psychology has a whole cottage industry in which people come up with some construct that is essentially "attitudes/beliefs/expectations/feelings about X", and then the central claim is that this construct is a super important determinant of future X outcomes.>

Congratulations to @yamilrvelez.bsky.social, @patrickpliu.bsky.social, and @scottclifford.bsky.social ! we think attitudes are some function of beliefs; our exps routinely move beliefs but not (even correlated) attitudes. This team found a way to guess which beliefs matter more (and they do!)

Yamil Ricardo Velez@yamilrvelez.bsky.social · 7mo ago

Conditionally accepted at the APSR (w/ @scottclifford.bsky.social & @patrickpliu.bsky.social): Why does political information so often change beliefs but NOT attitudes? We highlight the role of belief relevance, or the extent to which beliefs bear on attitudes.
