New paper with Don Green and @ethanvporter.bsky.social in the QJPS. After much deliberation, we went with a title that just states the result. 📝 journal: www.emerald.com/qjps/article...
abstract: While attempts to change Americans’ partisanship via persuasive treatments largely fail, partisanship can and does change over time. In this paper, the authors first confirm, via survey and field experiments, that typical campaign messaging in the United States does not budge partisanship. The authors then present experiments in which participants encounter extraordinary hypothetical scenarios (e.g. one party causes economic collapse) before reporting what their partisanship would be under such circumstances. Twelve percent of partisans imagine switching parties in the pro-out-party hypothetical conditions, compared with 5% in the control hypotheticals in which the status quo persists, for a seven-percentage point (SE 1.5 points) difference. These hypothetical shifts are on par with the largest changes in American macropartisanship ever recorded. While the act of ruminating on hypothetical scenarios is not followed by changes in partisanship measured post-treatment, the evidence suggests that extraordinary world events may be able to shift partisan affiliation.

BJPolS abstract discussing the challenges and proposal of a new typology for assessing citizen competence in sustaining democracy. The text addresses empirical data and suggests a solutions-oriented, systemic approach rather than individual-level interventions.

Fact-checks improve accuracy. But can they penalize spreaders of misinfo? At @polbehavior.bsky.social, Jacob Ausubel, Annika Davies and I show that the answer is yes--sometimes. Unknown misinfo producers can be penalized, but well-known figures get off. Link: link.springer.com/article/10.1...
