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.

APSR — pp. 1-19 2026-03-03 Original Partisan Expressive Responding: Lessons from Two Decades of Research MATTHEW H. GRAHAM Abstract Research on partisan expressive responding suggests that the beliefs people express in surveys are more partisan than their underlying perceptions. This article examines the scope and importance of expressive responding through a meta-reanalysis of 44 studies from 25 articles. On average, treatments designed to reduce expressive responding shrink measured partisan bias by about 25%. Across the 242 survey questions in the data, treatments increase the correlation between the average Democrat’s and Republican’s beliefs from 0.81 to 0.86. Contrary to expectations derived from the two leading theories of expressive responding, misreporting (“cheerleading”) and congenial inference, there is no evidence that expressive responding increases in partisan identity strength or educational attainment. As research on expressive responding enters its third decade, greater emphasis on design-based tests of mechanisms may help build a firmer understanding of the nature and substantive importance of expressive responding—namely, whether the forces that produce expressive responding in surveys also shape real-world political judgments.
