Abstract The American reaction to the COVID-19 pandemic is polarized, with conservatives often less willing to engage in risk-mitigation strategies such as mask-wearing and vaccination. COVID-19 narratives are also polarized, as some conservative elites focus on the economy over public health. In this registered report, we test whether combining economic and public health messages can persuade individuals to increase support for COVID-19 risk mitigation. We present preliminary evidence that the combination of messages is complementary, rather than competing or polarizing. When given a message emphasizing COVID-19’s negative health and economic effects in a pilot study, conservatives increased their support for a broad range of risk-mitigation strategies, while liberals maintained high levels of support. A preregistered larger-n follow-up study, however, failed to replicate this effect. While complementary frames may be a promising way to persuade voters on some issues, they may also struggle to overcome high levels of existing polarization.

Abstract Email can deliver mobilization messages at considerably lower cost than direct mail. While voters’ email addresses are readily available, experimental work from 2007 to 2012 suggests that email mobilization is ineffective in most contexts. Here, we use public data to reexamine the effectiveness of email mobilization in the 2016 Florida general election. Unsolicited emails sent from a university professor and designed to increase turnout had the opposite effect: emails slightly demobilizing voters. While the overall decrease in turnout amounted to less than 1 percent of the margin of victory in the presidential race in the state, the demobilizing effect was particularly pronounced among minority voters. Compared to voters from the same group who were assigned to control, black voters assigned to receive emails were 2.2 percentage points less likely to turn out, and Latino voters were 1.0 percentage point less likely to turn out. These findings encourage both campaigns and researchers to think critically about the use and study of massive impersonal mobilization methods.

Abstract Discussions around declining trust in the US media can be vague about its effects. One classic answer comes from the persuasion literature, in which source credibility plays a key role. However, existing research almost universally takes credibility as a given. To overcome the potentially severe confounding that can result from this, we create a hypothetical news outlet and manipulate to what extent it is portrayed as credible. We then randomly assign subjects to read op-eds attributed to the source. Our credibility treatments are strong, increasing trust in our mock source until up to 10 days later. We find some evidence that the resulting higher perceived credibility boosts the persuasiveness of arguments about more partisan topics (but not for a less politicized issue). Though our findings are mixed, we argue that this experimental approach can fruitfully enhance our understanding of the interplay between source trust and opinion change over sustained periods.

Abstract Overcoming vaccine hesitancy is critical to containing the COVID-19 pandemic in the United States. To increase vaccination rates, the State of Ohio launched a million dollar lottery in May 2021. Following a pre-registered analysis, we estimate the effects of Ohio’s lottery program Vax-a-Million on COVID-19 vaccination rates by comparing it to a “synthetic control” composed of eight other states. We find a statistically insignificant 1.3% decrease in the full vaccination rate in Ohio at the end of the lottery period. We investigate the robustness of our conclusion to model specifications through a multiverse analysis of 216 possible models, including longer time periods and alternative vaccination measures. The majority (88%) find small negative effects in line with the results of our pre-registered model. While our results are most consistent with a decrease in vaccination rate, they do not allow a firm conclusion on whether the lottery increased or decreased vaccine uptake.

Abstract The number of multiracial candidates seeking office is growing in an increasingly diverse America. This raises questions about how the media frame candidates with potentially complex racial backgrounds and how voters respond to these frames. We investigate the impact of media frames that emphasize race and gender attributes using survey experiments on Kamala Harris—the first Black woman and first Asian woman vice president. Our findings are mixed. In a survey experiment conducted after her nomination, headlines emphasizing different elements of Harris’s race or gender had no impact on public attitudes. In an experiment conducted after Harris was inaugurated, however, headlines that cued her gender only or both her gender and her Black racial background boosted popular support. Taken together, these findings suggest that some types of identity-based cues may matter, but the effects are sensitive to experimental settings and contexts.
