Response Options and the Measurement of Political Knowledge Apr 8, 2026 John G. Bullock; Kelly Rader, 2023, "Response Options and the Measurement of Political Knowledge", https://doi.org/10.60600/YU/H4HBEJ, Yale Dataverse, V2 By many measures, the public knows little about politics. But just how little people seem to know depends on the questions that are put to them. In particular, knowledge levels seem higher when people are asked closed- rather than open-ended questions. In turn, differences between estimated knowledge levels are sometimes attributed to fundamental d...
Does Digital Advertising Affect Vote Choice? Evidence from a Randomized Field Experiment Apr 8, 2026 Donald P. Green; Alexander Coppock; Ethan Porter, 2023, "Does Digital Advertising Affect Vote Choice? Evidence from a Randomized Field Experiment", https://doi.org/10.60600/YU/8KVYSY, Yale Dataverse, V2 Despite the increasing sums devoted to online political advertising, our understanding of the persuasive effects of such advertising is limited. We report the results of a ZIP code level randomized field experiment conducted over Facebook and Instagram during the 2018 U.S. midterm elections in Florida. The ads, produced by a Democratic-leaning poli...
Can the Political Ambition of Young Women Be Increased? Evidence from U.S. High School Students Apr 8, 2026 Joshua L. Kalla; Ethan Porter, 2022, "Can the Political Ambition of Young Women Be Increased? Evidence from U.S. High School Students", https://doi.org/10.60600/YU/A2S7NA, Yale Dataverse, V2 The under-representation of women in American politics can likely be explained, at least in part, by women's comparatively lower levels of political ambition. We analyze a co-ed, religious program for high school students in which participants lobby their Members of Congress and receive political skills training. By leveraging longitudinal survey d...
Identifying Legitimacy: Experimental Evidence on Compliance with Authority Apr 8, 2026 Eric Dickson; Sanford Gordon; Gregory Huber, 2022, "Identifying Legitimacy: Experimental Evidence on Compliance with Authority", https://doi.org/10.60600/YU/6MVZSU, Yale Dataverse, V2 To what extent do individuals’ perceptions of legitimacy affect their intrinsic motivations to comply with an authority? Answering this question has critical implications for law enforcement but is challenging because actions or institutions that affect intrinsic motivations typically also affect extrinsic, material ones. To disentangle these, we p...
Testing the Efficacy of Three Informational Interventions for Reducing Misperceptions of the Black–White Wealth Gap Apr 8, 2026 Bennett Callaghan; Leilah Harouni; Cydney H. Dupree; Michael Kraus; Jennifer Richeson, 2022, "Testing the Efficacy of Three Informational Interventions for Reducing Misperceptions of the Black–White Wealth Gap", https://doi.org/10.60600/YU/IEDYFO, Yale Dataverse, V2 Americans remain unaware of the magnitude of economic inequality in the nation and the degree to which it is patterned by race. We exposed a community sample of respondents to one of three interventions designed to promote a more realistic understanding of the Black–White wealth gap. The interventions conformed to recommendations in messaging about...
"Outside Lobbying” Over the Airwaves: A Randomized Field Experiment on Televised Issue Ads Apr 8, 2026 Joshua L. Kalla; David E. Broockman, 2022, ""Outside Lobbying” Over the Airwaves: A Randomized Field Experiment on Televised Issue Ads", https://doi.org/10.60600/YU/8ESLSV, Yale Dataverse, V2 We present the first field experiment on how organized interest groups’ television ads affect issue opinions. We randomized 31,404 voters to three weeks of interest group ads about either immigration or transgender nondiscrimination. We then randomly assigned voters to receive ostensibly unrelated surveys either while the ads aired, one day after t...
Economic Decline, Social Identity, and Authoritarian Values in the United States Apr 8, 2026 Cameron Ballard-Rosa; Amalie Sofie Jensen; Kenneth Scheve, 2022, "Economic Decline, Social Identity, and Authoritarian Values in the United States", https://doi.org/10.60600/YU/6XTQSD, Yale Dataverse, V2 Why does the contemporary backlash against globalization in the United States have such a substantial authoritarian character? We argue that sustained economic decline has a negative effect on the social identity of historically dominant groups. These losses lead individuals to be more likely to want to enforce social norm conformity—that is, adopt...
