Our (with Radha Sarkar) meta-reanalysis of the experimental religion and politics literature is now out at @apsrjournal.bsky.social Open-access link: doi.org/10.1017/S000... Brief thread
title page of journal, that reads:

The effects of religious messages and endorsements on political attitudes: A meta-reanalysis
Sarkar, Radha, Coppock, Alexander. 2026. The effects of religious messages and endorsements on political attitudes: A meta-reanalysis. American Political Science Review.

Abstract
The experimental study of the effects of religious messages and endorsements by religious leaders on political attitudes has a relatively short history yet has coalesced around three main claims: religious treatments are especially effective because of their religious character, effects are larger for religious affiliates than nonaffiliates, and effects are larger for high religiosity types than low religiosity types. Here we meta re-analyze the experimental record (58 treatment-outcome pairs drawn from 43 studies reported in 26 papers) to probe the generalizability of these claims. Our findings indicate that these three headline claims do not generalize straightforwardly across contexts: effects are large in some cases and close to zero in others, and we find no evidence in favor of the claimed heterogeneities by religious affiliation or religiosity. Based on a census of the estimands in this literature, we offer suggestions for future research that would enhance commensurability and synthesis.

🧵 Why do facts often change beliefs but not attitudes? In a new WP with @yamilrvelez.bsky.social and @scottclifford.bsky.social, we caution against interpreting this as rigidity or motivated reasoning. Often, the beliefs *relevant* to people’s attitudes are not what researchers expect.

I am really pleased to see our meta-analysis of media literacy interventions (160 studies!) has been published in HCR. Unsurprisingly, there is a lot of nuance. One piece of good news is that the interventions work longitudinally. Free download here: academic.oup.com/hcr/advance-...

So far persuasion work in polisci has mostly centered on message -> opinion (main result imo: messages have small fx in the right direction that don't differ too much by message or person or issue) with less work on message -> attention need to figure out experimental paradigm for attention

Our meta-analysis of 2018-20 ad experiments is now out at APSR! paper (open-access): doi.org/10.1017/S0003055423001387 Tagging bluesky coauthors @dbroockman.bsky.social, @benmtappin.bsky.social and @jslez.bsky.social Thread ⬇️
Abstract: 

Political campaigns increasingly conduct experiments to learn how to persuade voters. Little research has considered the implications of this trend for elections or democracy. To probe these implications, we analyze a unique archive of 146 advertising experiments conducted by US campaigns in 2018 and 2020 using the platform Swayable. This archive includes 617 advertisements produced by 51 campaigns and tested with over 500,000 respondents. Importantly, we analyze the complete archive, avoiding publication bias. We find small but meaningful variation in the persuasive effects of advertisements. In addition, we find that common theories about what makes advertising persuasive have limited and context-dependent power to predict persuasiveness. These findings indicate that experiments can compound money’s influence in elections: it is difficult to predict ex ante which ads persuade, experiments help campaigns do so, but the gains from these findings principally accrue to campai
