Abstract

Scholars warn that partisan divisions in the mass public threaten the health of American democracy. We conducted a megastudy (n = 32,059 participants) testing 25 treatments designed by academics and practitioners to reduce Americans’ partisan animosity and antidemocratic attitudes. We find that many treatments reduced partisan animosity, most strongly by highlighting relatable sympathetic individuals with different political beliefs or by emphasizing common identities shared by rival partisans. We also identify several treatments that reduced support for undemocratic practices – most strongly by correcting misperceptions of rival partisans’ views or highlighting the threat of democratic collapse – which shows that antidemocratic attitudes are not intractable. Taken together, the study’s findings identify promising general strategies for reducing partisan division and improving democratic attitudes, shedding theoretical light on challenges facing American democracy.

  • There is no direct evidence linking ideological extremity to antidemocratic behaviors among elites, but such evidence exists among citizens.

    “While there is no direct evidence linking ideological extremity to antidemocratic behaviors among elites, there does exist such evidence among citizens (e.g., Graham & Svolik, 2020;Voelkel, Stagnaro, et al., 2023).”

    From How to study democratic backsliding (2024) · cites this paper as Voelkel, Stagnaro, et al., 2023

    The ‘Differences between Ideological Moderate and Ideological Extreme People’ section (Table S6.7; page not specified) finds that more ideologically extreme participants reported greater support for undemocratic practices, partisan violence, and undemocratic candidates. These are reported attitudes, not observed antidemocratic behaviors, so the cited study does not establish the behavioral link claimed for citizens. The citation is attached to the citizen-evidence portion of the sentence, not the statement about elites. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
