ISPS Data Archive

Part of the Yale Institution for Social and Policy Studies (ISPS) Dataverse, the ISPS Data Archive includes “replication packages” (i.e., data, analysis code, requisite documentation, and other associated materials) for research supported by ISPS. Replication packages have been reviewed to enable long-term usability using the YARD tool. Read about our approach to curating for reproducibility.

Sources of Bias in Retrospective Decision Making: Experimental Evidence on Voters’ Limitations in Controlling Incumbents Apr 8, 2026 Gregory Huber; Seth J. Hill; Gabriel S. Lenz, 2014, "Sources of Bias in Retrospective Decision Making: Experimental Evidence on Voters’ Limitations in Controlling Incumbents", https://doi.org/10.60600/YU/DCNMXL, Yale Dataverse, V2 Are citizens competent to assess the performance of incumbent politicians? Observational studies cast doubt on voter competence by documenting several biases in retrospective assessments of performance. However, these studies are open to alternative interpretations because of the complexity of the real world. In this article, we show that these bia...
Personality and the Strength and Direction of Partisan Identification Apr 8, 2026 Alan S. Gerber; Gregory Huber; David Doherty; Conor M. Dowling, 2013, "Personality and the Strength and Direction of Partisan Identification", https://doi.org/10.60600/YU/IO8VSO, Yale Dataverse, V2 We examine the associations between personality traits and the strength and direction of partisan identification using a large national sample. We theorize that the relationships between Big Five personality traits and which party a person affiliates with should mirror those between the Big Five and ideology, which we find to be the case. This sugg...
Assessing the Stability of Psychological and Political Survey Measures Apr 8, 2026 David Doherty; Gregory Huber; Alan S. Gerber; Conor M. Dowling, 2013, "Assessing the Stability of Psychological and Political Survey Measures", https://doi.org/10.60600/YU/HZ2OY5, Yale Dataverse, V2 Recent research demonstrates growing scholarly interest in the relationship between personality characteristics and political attitudes and behaviors. In this article we present analysis using data from a national panel survey conducted in two waves—the first prior to the 2010 U.S. midterm election, the second after it. We assess the stability of a...
Is There a Secret Ballot? Ballot Secrecy Perceptions and Their Implications for Voting Behaviour Apr 8, 2026 Alan S. Gerber; Gregory Huber; David Doherty; Conor M. Dowling, 2013, "Is There a Secret Ballot? Ballot Secrecy Perceptions and Their Implications for Voting Behaviour", https://doi.org/10.60600/YU/FHS5P3, Yale Dataverse, V2 Do people believe the votes they cast are truly secret? Novel items added to a nationally representative survey show that 25 per cent of respondents report not believing their ballot choices are kept secret and over 70 per cent report sharing their vote choices with others. These findings suggest that standard models of candidate choice should acco...
Emails from Official Sources Can Increase Turnout Apr 8, 2026 Neil Malhotra; Melissa Michelson; Ali Valenzuela, 2014, "Emails from Official Sources Can Increase Turnout", https://doi.org/10.60600/YU/SCUYUK, Yale Dataverse, V2 Previous research by Nickerson (2007a) testing 13 email get-out-the-vote (GOTV) campaigns concludes that email from third parties is not an effective method of increasing voter turnout. We conducted three rounds of email GOTV experiments in San Mateo County, California, in cooperation with the local registrar, the elected official responsible for a...
Which Elections Can Be Lost? Apr 8, 2026 Nikolay Marinov; Susan D. Hyde, 2013, "Which Elections Can Be Lost?", https://doi.org/10.60600/YU/2XL4V3, Yale Dataverse, V2 The concept of electoral competition is relevant to a variety of research agendas in political science, yet the question of how to measure electoral competition has received little direct attention. We revisit the distinction proposed by Giovanni Sartori between competition as a structure or rule of the game and competitiveness as an outcome of tha...
Voter Attitudes When Democracy Promotion Turns Partisan: Evidence From a Survey-Experiment in Lebanon Apr 8, 2026 Nikolay Marinov, 2012, "Voter Attitudes When Democracy Promotion Turns Partisan: Evidence From a Survey-Experiment in Lebanon", https://doi.org/10.60600/YU/VERU3G, Yale Dataverse, V2 This article studies how voters react when foreign powers support a particular political party in a fragile democracy. The article identifies which voters believe the intervention plays a positive role in the electoral process and which voters have the opposite opinion. The article argues that educated and politically sophisticated voters will reje...

Does Less Income Mean Less Representation? Apr 8, 2026 Eric Brunner; Stephen L. Ross; Ebonya Washington, 2013, "Does Less Income Mean Less Representation?", https://doi.org/10.60600/YU/YUVYJP, Yale Dataverse, V2 We assemble a novel dataset of matched legislative and constituent votes and demonstrate that less income does not mean less representation. We show: (i) The opinions of high- and low-income voters are highly correlated; the legislator's vote often reflects the desire of both. (ii) What differences in representation by income exist vary by legislat...
Cognitive Biases and the Strength of Political Arguments Apr 8, 2026 Kevin Arceneaux, 2012, "Cognitive Biases and the Strength of Political Arguments", https://doi.org/10.60600/YU/LLY9L4, Yale Dataverse, V2 Competition in political debate is not always sufficient to neutralize the effects of political rhetoric on public opinion. Yet little is known about the factors that shape the persuasiveness of political arguments. In this article, I consider whether cognitive biases influence the perceived strength of political arguments, making some arguments mo...
