Can the Government Deter Discrimination? Evidence from a Randomized Intervention in New York City Joint with Andrew M. Guess and Macartan Humphreys. Forthcoming, The Journal of Politics.
Racial discrimination persists despite established anti-discrimination laws. A common government strategy to deter discrimination is to publicize the law and communicate potential penalties for violations. We study this strategy by coupling an audit experiment with a randomized intervention involving nearly 700 landlords in New York City and report the first causal estimates of the effect on rental discrimination against Blacks and Hispanics of a targeted government messaging campaign. We uncover discrimination levels higher than prior estimates indicate, especially against Hispanics, who are approximately six percentage points less likely to receive callbacks and offers than whites. We find suggestive evidence that government messaging can reduce discrimination against Hispanics, but not against Blacks. The findings confirm discrimination’s persistence and suggest that government messaging can address it in some settings, but more work is needed to understand the contexts under which such appeals are most effective.
Do Subtle Linguistic Interventions Priming a Social Identity as a Voter Have Outsized Effects on Voter Turnout? Evidence from a New Replication Experiment. Joint with Alan S. Gerber and Gregory A. Huber. Forthcoming, Political Psychology.
An ongoing debate in political psychology is about whether small wording differences have outsized behavioral effects. A leading example is whether subtle linguistic cues embedded in voter mobilization messages dramatically increase turnout. An initial study analyzing two small-scale field experiments argued that describing someone as a voter (noun) instead of one who votes (verb) increases turnout rates 11 to 14 points because the noun activates a person’s social identity as a voter. A subsequent study analyzing a large-scale field experiment challenged this claim and found no effect. But questions about the initial claim’s domain of applicability persist. The subsequent study may not have reproduced the conditions necessary for the psychological phenomenon to occur, specifically the electoral contexts were not competitive or important enough for the social identity to matter. To address the first of these critiques, as well as other potential explanations for different results between the first two studies, we conduct a large-scale replication field experiment. We find no evidence that this minor wording change increases turnout levels. This research provides new evidence that the strategy of invoking the self does not appear to consistently increase turnout and calls into question whether subtle linguistic cues have outsized behavioral effects.
The Effect on Turnout of Campaign Mobilization Messages Addressing Ballot Secrecy Concerns: A Replication Experiment. Joint with Alan S. Gerber, Gregory A. Huber, and Catlan E. Reardon. 2017. PLOS ONE. 12(8): e0182199.
Given the persistence of public doubts about the integrity of ballot secrecy, which depress turnout, two prior experiments have shown precise evidence that both official governmental and unofficial mobilization campaigns providing assurances about ballot secrecy increase turnout among recently registered nonvoters. To assess whether these findings replicate in other political settings, we describe a replication experiment where a non-governmental, non-partisan mobilization campaign sent similar treatment mailings containing assurances about ballot secrecy protections to recently registered nonvoters during the 2014 general election in Mississippi. We find that sending this mailer has no effect on turnout rates in this setting, which is characterized by an unusually low baseline turnout rate. These results are consistent with past research concluding that nonpartisan Get Out The Vote (GOTV) mail has very weak effects among very low turnout propensity registrants, and suggest that there are heterogeneous effects of ballot secrecy treatments associated with subjects’ characteristics and the electoral context.
Nongovernmental Campaign Communication Providing Ballot Secrecy Assurances Increases Turnout: Results from Two Large-Scale Experiments. Joint with Alan S. Gerber, Gregory A. Huber, and Andrew Gooch. 2017. Political Science Research and Methods.
Doubts about the integrity of ballot secrecy persist and depress political participation among the American public. Prior experiments have shown that official communications directly addressing these doubts increase turnout among registered voters who had not previously voted, but evaluations of similar messages sent by non-governmental campaigns have yielded only suggestive effects. We build on past research and analyze two large-scale field experiments where a private non-partisan non-profit group sought to increase turnout by communicating ballot secrecy assurances in a direct mail voter mobilization campaign during the 2014 midterm election. Our main finding is that a private group’s mailing increases turnout by about 1 percentage point among registered nonvoters. This finding is precisely estimated and robust across state political contexts.
The Generalizability of Social Pressure Effects on Turnout Across High-Salience Electoral Contexts: Field Experimental Evidence from 1.96 Million Citizens in 17 States. Joint with Alan S. Gerber, Gregory A. Huber, and Andrew Gooch. 2017. American Politics Research. 45(4): 533-559.
Prior experiments show that campaign communications revealing subjects’ past turnout and applying social pressure to vote (the “Self” treatment) increase turnout. However, nearly all existing studies are conducted in low salience elections, raising concerns that published findings are not generalizable and are an artifact of sample selection and publication bias. Addressing the need for further replication in high salience elections, we analyze a field experiment involving 1.96 million subjects where a nonpartisan campaign randomly sent Self treatment mailers, containing a subject’s vote history and a comparison of each subject’s history to their state median registrant’s turnout behavior, in high salience elections across 17 states in 2014. Sending the Self mailer increases turnout by 0.7 points, or 2.2%. This effect is largely consistent across states, with somewhat larger effects observed in states with lower ex ante election salience. Our study provides precise evidence that social pressure effects on turnout are generalizable.
