APSR — pp. 1-22 2026-06-10 Original The Effects of Religious Messages and Endorsements on Political Attitudes: A Meta-Reanalysis RADHA SARKAR, ALEXANDER COPPOCK 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-reanalyze 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.

PMR — pp. 1-33 2026-03-30 Original Experiments in public administration research: contributions, challenges, and the road ahead Ricardo C. Gomes, Gustavo M. Tavares, Gustavo Mirapalheta Abstract Experiments are essential for testing theory and evaluating policy interventions as they uniquely enable causal inference. This study provides a primer on experimental and quasi-experimental methods and reviews their use in public administration research by analysing 1,143 articles through bibliometric and regression techniques. It focuses on laboratory, field, survey-based, and quasi/natural experiments. The findings reveal rapid growth in experimental research, particularly survey-based experiments, which now dominate the field. Key theoretical clusters, themes, and references are identified, and statistical analyses investigate the link between experiment type and citation counts. The study concludes with recommendations for advancing experimental research in public administration.
