Why do parties do what they do? Excited to share my 2nd dissertation paper, just published in @jeppjournal.bsky.social
In the paper, I argue that parties seek internal unity and try to keep the team together: www.tandfonline.com/doi/full/10....

🎺 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

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.

Go home prediction markets: you’re drunk

Political prediction markets moved billions in 2024, but new evidence shows they weren’t very accurate or efficient

PredictIt beat chance 93% of the time

Kalshi? 78%

How do attitudes to 🇪🇺 European integration relate to political ideology and policy preferences?

A major update of my study:
- I added the latest 2023 ESS data for citizens and 2024 CHES data for parties
- I built an app to explore these relationships across datasets, indicators, years & countries
Average support for further European integration of citizens (blue line, based on GAM with cubic regression splines) and positive orientation towards European integration of political parties (black dots and red line, based on a local polynomial regression) as functions of left-right self-placement of the citizens and general left-right party positions as estimated by experts. Originally, party positions on European integration are scored on a 1-to-7 scale, which has been rescaled from 0 to 10 to match the public opinion data. Data: ESS Wave 11 (2023), CHES (2024).

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**.

Paper: arxiv.org/pdf/2509.08825
We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation". We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks. For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations. Then, we collect 13 million LLM annotations across plausible LLM configurations. These annotations feed into 1.4 million regressions testing the hypotheses. For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions. Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors. Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models. Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.
