I put together this "experiment checklist" for the grad students in my experiments class -- practical advice for experimental design. www.dropbox.com/scl/fi/lwbco...

For folks headed to MPSA next week, the Association for Politics and the Life Sciences is hosting an open conference within a conference! Friday afternoon in Monroe, free food & drinks, & the events are a typical research panel (1:15) & a roundtable (3:20) on doing research during -these times-.

We have created a masterpiece

Why wait? I still have leftover hotdogs and I think we can make this haappen!

New paper out in @thejop.bsky.social : "Immigration, Public Housing, and Support for the French National Front."

How does expanding public housing affect far-right support? The answer depends heavily on local conditions, and specifically on local immigrant shares.

Paper: doi.org/10.1086/736361

Our element (with the amazing Yanna Krupnikov and @lrpalladino.bsky.social ) is *free to download* for the next few weeks! @cambup-polsci.cambridge.org

Across six pre-registered experiments, we find people are skeptical of emotional expression about this critical issue (even when observers themselves are worried about climate change). And, evaluations depend at least in part on the platform through which they encounter those emotions.

Here we focus on the case of people getting emotional about climate change -- an increasingly emotional issue! I see people expressing their feelings about climate change in my social media feed all the time (and research suggests I'm not alone).

Emotions on Our Screens Cambridge Core - Politics: General Interest - Emotions on Our Screens

Now more than ever we encounter each other's emotions about politics, on social media and in the news. When do we take strangers' emotional expression seriously, and when do we dismiss it as inappropriate or even insincere? You can find out now in our Cambridge Element!

Do you need to measure precise preferences for visual outcomes with very little survey space? Markus Prior, Justin Curl, and I have some solutions for you! Now officially published in @polanalysis.bsky.social doi.org/10.1017/pan....

ICYMI my solo article on MENA identity.

When MENA Americans aren’t given a “MENA” option on forms, they answer identity-related questions on politics more strongly (eg higher end of the scale) than if“MENA” had been added.

Having the group label or not changes the average response!

New paper out in Ecological Economics with @gonzalezrostani.bsky.social and @aklin.bsky.social! We look at how long-term labor market risk from automation shapes people's environmental attitudes and climate policy preferences 🧵

My book - “Purges” - has a release date (August 15) and a front cover. I started work on this as my PhD dissertation at the end of 2017 - excited for it to finally be coming out!

We’re so excited to read your great experimental work!

⏳One month left to nominate papers for APSA's Experimental Research Section’s Best Paper Award! We’re excited to read creative experimental work tackling big political questions. Self-nominations welcome (and discussants, please nominate your panelists)!

The sky is not falling; high-quality platforms (Prolific, Verasight, CR Connect) have low rates of apparent bots. osf.io/preprints/ps... But also not zero; vigilance is very much needed!

Sea level much higher than assumed in most coastal hazard assessments - Nature Meta-analyses on a global scale show that the measured coastal mean sea level is higher than assumed in most coastal hazard assessments.

New paper out today suggests sea level rise may be substantially worse than we thought due to underestimates in models. What do all you slr modelers out there think of this paper??? www.nature.com/articles/s41...

I wrote something. I hope it can be the start of more conversations about AI and the choices we all have to make.

Very excited to see this out at @bjpols.bsky.social! In this article, I show that contemporary political news coverage makes it challenging for readers to learn information that is helpful for democratic accountability, even for very politically engaged audiences.

A brief summary:

Rural Versus Urban: The Growing Divide That Threatens Democracy by Suzanne Mettler and Trevor E. Brown

Suzanne Mettler

This Saturday (Jan 31) at 2:00 pm EST, see @smettler.bsky.social, co-author of Rural Versus Urban, give a lecture as part of the National Writers Series! She will discuss her book and how the urban-rural divide drives partisan polarization.

Get tickets for this hybrid event here: buff.ly/2QZ3VnT

Big congrats to @povertyscholar.bsky.social and @profsorelle.bsky.social on the publication of this important new book, which I cannot wait to read!

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
4️⃣ publish your study

applications open Feb 1

Ahem. Political science is the *best* science.

In all seriousness: Political scientists use the scientific method. And it's not like the political world is mystical/made-up. Assuming a closed physical universe, human behavior has some explanation - it's just hard to identify.*

*In all senses

We are seeking a Fellow to lead cutting-edge research on short-form video content and its societal implications. Bridging the gap between computer vision, causal inference, and computational social science, the Fellow will focus on the large-scale analysis of TikTok data (using an existing, massive dataset). The position involves developing novel multimodal methods to understand how short-form algorithmic content shapes public opinion, political polarization, and online culture. This is a unique opportunity to work at the forefront of the field, combining rigorous social science research designs with state-of-the-art computational techniques.

The Center for Information Technology Policy at Princeton invites applications for a Postdoctoral Fellow to work with an interdisciplinary team (me, @bstewart.bsky.social, and @manoelhortaribeiro.bsky.social).

Please apply by THIS SUNDAY, Dec. 14!

Currently in FirstView: In “Meaning Beyond Numbers: Introducing the Plot Staircase to Measure Graphical Preferences,” @talbotmandrews.bsky.social, Justin Curl, and Markus Prior examine how visual characteristics influence preferences. They find that people prefer increasing trends.

Trump Is Kneecapping Some of the Boldest Plans to Fight Climate Change Donald Trump's assault on climate innovation is also affecting scientists researching geoengineering methods like carbon-dioxide removal.

@hollyjeanbuck.bsky.social, @davidho.bsky.social and I were interviewed by @rollingstone.com about the Trump admin and Climate Intervention research. Compared to initial hopes/worries, Trump admin has shown zero interest to support any kind of climate research.

ANES Data Release! electionstudies.org/data-center/...

The 3-wave ANES panel is now available. It merges data from 3 election studies (2016-2020-2024), the first time the ANES has collected interviews of the same respondents across 3 presidential elections.
