Replication Data for: How Language Shapes Belief in Misinformation: A Study Among Multilinguals in Ukraine
Jun 25, 2025
Erlich, Aaron; Aslett, Kevin; Graham, Sarah; Tucker, Joshua, 2025, "Replication Data for: How Language Shapes Belief in Misinformation: A Study Among Multilinguals in Ukraine", https://doi.org/10.7910/DVN/YEAJ85, Harvard Dataverse, V1
Scholarship has identified key determinants of people's belief in misinformation, predominantly from English-language contexts. However, multilingual citizens often consume news media in multiple languages. We study how language of consumption affects belief in misinformation and true news articles in multilingual environments. We suggest that lang...

Replication Data for: Pro-equality initiatives increase expressed sexism among men but may improve trust among women football fans
Jun 19, 2025
Gatto, Malu; Araújo, Victor, 2025, "Replication Data for: Pro-equality initiatives increase expressed sexism among men but may improve trust among women football fans", https://doi.org/10.7910/DVN/OS4PSG, Harvard Dataverse, V1, UNF:6:q5kSRH8D+zZz3N0mZIS1pQ== [fileUNF]
Globally, prejudicial attitudes towards women persist. By taking anti-discriminatory stances, value-oriented organisations---e.g., political parties and religious denominations---can tap into group identities to shape their members’ attitudes. We know much less about the role of organisations that are not inherently value-oriented---such as sports...
Replication Data for: Legislator Responsiveness to Racialized Constituencies in Mexico
Jun 9, 2025
Muzquiz, Jose; Alcocer, Jose Javier, 2025, "Replication Data for: Legislator Responsiveness to Racialized Constituencies in Mexico", https://doi.org/10.7910/DVN/VS3GL8, Harvard Dataverse, V1, UNF:6:CKZ9gThLTt8ULTsOU3zrHQ== [fileUNF]
This study examines how racial identity affects legislative responsiveness in Mexico using an email-based audit experiment. Emails from simulated Indigenous, Mestiza, and European-White constituents were sent to all 626 federal legislators to test whether perceived identity shapes replies and their quality. Contrary to expectations, Indigenous-name...
Replication Data for: Re-stigmatizing the radical right: A one-way street?
Replication Data for: Re-stigmatizing the radical right: A one-way street?
Jun 3, 2025
Balcells, Laia; Martínez, Sergi; Valentim, Vicente; vanderWilden, Ethan, 2025, "Replication Data for: Re-stigmatizing the radical right: A one-way street?", https://doi.org/10.7910/DVN/QPTLBA, Harvard Dataverse, V1
Radical-right behavior and support for radical-right parties have increased across many countries in recent decades. A growing body of research has argued that, similar to the spread of other extremist behaviors, this is due to an erosion of political norms. This suggests that re-stigmatizing radical-right parties might be an effective way of count...
Replication Data for: Status Threat, Partisanship, and Voters' Conservative Shift toward Right-wing Candidates
May 21, 2025
Ferrari, Diogo; Brianna Smith, 2025, "Replication Data for: Status Threat, Partisanship, and Voters' Conservative Shift toward Right-wing Candidates", https://doi.org/10.7910/DVN/AUMLXM, Harvard Dataverse, V1
Past research indicates that support for conservatism increases when individuals perceive threat to their group's social status—i.e., prestige and respect. However, the causal link between status threat and increased electoral support for conservative candidates has not been established. Most prior studies rely on observational data, and it remains...

Replication Data for: Life-or-Death Framing of Public-Health Policy in a Pandemic
Apr 22, 2025
Gaines, Brian, 2025, "Replication Data for: Life-or-Death Framing of Public-Health Policy in a Pandemic", https://doi.org/10.7910/DVN/EJ8UZQ, Harvard Dataverse, V1
The justifiably famous "Asian disease" experiment (ADE) by Tversky and Kahneman established that choices involving uncertainty can be dependent on framing. Description emphasizing gains induced much higher preference for choices in which outcomes were described as certain rather than probabilistic, as compared to description emphasizing losses. The...
