How Cross-Cutting Ties Reduce Affective Polarization: Evidence from Latino Americans - Political Behavior Affective polarization—that is, personal dislike and distrust between Democrats and Republicans—is argued to arise, at least in part, from fewer cross-cutting ties that bridge Democrats and Republican...

Across multiple datasets, researchers find that cross-cutting social ties predict warmer out-party feelings, and Latino Americans, who hold more of these ties, consistently exhibit lower affective polarization.

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

Political Behavior NOTE FROM THE EDITORS OF POLITICAL BEHAVIOR: We have recently transitioned from Editorial Manager to SNAPP. The submission process for SNAPP requires ...

Political Scientists: I am the chair of the committee that is picking the next editor of @polbehavior.bsky.social. If you are interested, I'd be happy to chat about it (and I know the current editors would be too).

Impressive for sure but that y-axis truncation is doing a lot of work as well...

In political science, sample sizes, placebo tests, preanalysis plans, and power analyses are on the rise.

While our @polbehavior.bsky.social paper primarily shows that people ascribe partisanship to cultural activities/hobbies etc., there is a larger literature linking social sorting to affective polarization. And politicizing/polarizing culture means that people become sorted on even more categories.

Graph showing perceptions of which activities/hobbies people perceive as Democratic or Republican. Some of the most Republican coded categories are gun, hunting, NASCAR, church, boots, and country music.

"a woman who hates Christianity, will take away your guns [...] and openly disdains Country music"

Clear example of politicization of culture, which may solidify social sorting and facilitate us-vs-them categorization and in turn can fuel affective polarization

How do people form beliefs about complex topics?

Happy to report our Bayesian model of the psychology of Bayesian updating is out in @ispp-pops.bsky.social! (w/ Gabriel Li & Krosnick)

If you gloss over the Greek, it's a new model for how to assess the impacts of information on summary judgments.

‼️ Two weeks left to apply for the postdoc in Political Text Analysis in the MULTIREP project 👇.

Our paper on how cross-cutting group memberships predict warmer out-party affect and analyses suggesting this is why Latinos in the US have warmer feelings toward the out-party is now fully published in the most recent @polbehavior.bsky.social issue.

Do any meta-analyses or other reflection pieces exist that catalog the sorts of mechanisms specifically, and outcomes generally, studied as consequences of providing white Americans information on their declining population share?

Totally, I agree. It's an important proof of concept but given the profit margin mentioned in the paper and the ease of automating all processes, this could quickly become quite profitable (in the short term).

Drew, I have some news for you ;)

Yes but the paper also demonstrates that (1) even a few such LLM generated respondents can skew responses, and (2) that there is a clear business model whereby opt-online panels can be used to make money using such agents.

Important paper. So far most of the potential solutions I've seen mentioned (in-person surveys, high-quality/validated panels, address-based sampling) cost lots of money and will thus deepen divides based on resources. Something that we'll also need to grapple with.

Are victimhood claims in political party manifestos and election programs on the rise? Yes, they are! Check out a brand new paper authored by @marlenevoit.bsky.social , @lucaskohler.bsky.social et al. -- published yesterday in @polpsyispp.bsky.social. Open Access: doi.org/10.1111/pops....

Across social media sites, political posting is tightly linked to affective #polarization - the most partisan users post the most

As casual users disengage & polarized partisans remain vocal, the online public sphere grows smaller, sharper, and more ideologically extreme

Pleased to share that the @aapor.bsky.social report looking at 2024 election polling is out now: aapor.org/wp-content/u...

After a huge post-election flip in economic perceptions, I thought Democrats and Republicans might be lying to pollsters to send a partisan message — but I was wrong!

This is awesome Drew! I think this will lead to a ton of really interesting discussions
