Keep your promises, even when your peers do not
This study measures the effect of partisan and polarizing social media messages on political trust and trustworthiness in Brazil and Mexico. We implemented two survey experiments with approximately 2,300 respondents each, using a modified “trust game” to measure the effects of polarizing social media messages on two dimensions: trust (the belief that others will fulfill their pledges) and trustworthiness (fulfilling the pledges made to others). A…
Survey Professionalism
Online panels have become an important resource for research in political science, but the compensation offered to panelists incentivizes them to become “survey professionals,” raising concerns about data quality. We provide evidence on survey professionalism exploring three US samples of subjects who donated their browsing data, recruited via Lucid, YouGov, and Facebook (total $n = 3,886$ ). Survey professionalism is common, but varies across sa…
Misinformation Beyond Traditional Feeds
The fact-checking dilemma
This study examines how exposure to counter- and pro-attitudinal fact-checking messages impacts the fact-checker’s perceived quality and ideological leaning. In a well-powered and pre-registered survey experiment conducted during the 2021 mid-term election in Argentina, when COVID-19 was a polarizing issue, we exposed 5757 respondents to real tweets reporting the number of COVID-19 cases, followed by fact-checking adjudications that appropriately…
Voting for Law and Order
In this article, we examine the demand-and-supply dynamic of security policies. We argue there are two informational shortcuts through which voters process policy alternatives and choose among them: (1) their own personal experiences with violence and (2) candidates’ profiles. We test our argument through an original survey experiment conducted in Mexico. We model voters’ decisions to support candidates campaigning over a variety of security prop…
Training Computational Social Science PhD Students for Academic and Non-Academic Careers
Social scientists with data science skills increasingly are assuming positions as computational social scientists in academic and non-academic organizations. However, because computational social science (CSS) is still relatively new to the social sciences, it can feel like a hidden curriculum for many PhD students. To support social science PhD students, this article is an accessible guide to CSS training based on previous literature and our col…
Network activated frames
Our article describes how users’ decisions to share content alter the frequencies of the frame elements observed by social media peers. Changes in the frequency of distinct frame elements shape how individuals interpret, classify and define situations and events. We label this process Network Activated Frames (NAFs). We test the mechanisms behind NAF with an original image-based conjoint design that replicates network activation in three surveys.…
Truth be told
When do users share fact-checks on social media? We describe a survey experiment conducted during the 2019 election in Argentina measuring the propensity of voters to share corrections to political misinformation that randomly confirm or challenge their initial beliefs. We find evidence of selective sharing—the notion that individuals prefer to share pro-attitudinal rather than counter-attitudinal fact-checks. This effect, however, is conditioned…
The Effect of Streaming Chat on Perceptions of Political Debates
Broadcast media consumption is becoming more social. Many online video “livestreams” come with embedded livestreaming chatboxes, uniting the on-screen and social components. We investigate how streaming chat shapes perceptions of political events. We conducted a field experiment during the September 2019 Democratic Primary Debate where subjects were assigned to view the debate with or without streaming chat. We use text analyses to characterize t…
News Sharing, Gatekeeping, and Polarization
What explains news sharing in polarized social media environments? Will polarization of the audiences further polarize news organizations? In this article, we connect existing theories of news sharing and gatekeeping to describe the conditions under which social media polarization will increase polarization among news organizations. Our results show that a polarized readership will further polarize news organizations. However, polarization will b…
News by Popular Demand
Social media news sharing has become a central subject of scholarly research in communication studies. To test current theories, it is of an utmost importance to estimate the meaningful parameters of news sharing behavior from observational data. In this article, we retrieve measures of ideological congruence, issue salience, and media reputation to explain news sharing in social media. We describe how the proposed statistical model connects to d…

Will I Get Covid-19? Partisanship, Social Media Frames, and Perceptions of Health Risk in Brazil - Corrigendum
Will I Get Covid-19? Partisanship, Social Media Frames, and Perceptions of Health Risk in Brazil
In these polarized and challenging times, not even perceptions of personal risk are immune to partisanship. This article introduces results from a new survey with an embedded social media experiment conducted during the first months of the COVID-19 pandemic in Brazil. Descriptive results show that progovernment and opposition partisans report very different expectations of health and job risks. Job and health policy have become wedge issues that …
O Partido dos Trabalhadores e as Instituições Participativas
O artigo argumenta que a dinâmica intrapartidária do Partido dos Trabalhadores (PT) explica a emergência de políticas públicas participativas nas administrações municipais desta organização e que acabaram diferenciando-a da tradição de pouco enraizamento social dos partidos políticos no Brasil. Utilizando de forma pioneira dados do Processo de Eleições Diretas do PT no nível local, analisamos como a dinâmica das facções do partido interfere na pr…

O Partido dos Trabalhadores na Câmara dos Deputados
Este artigo analisa a evolução das bases eleitorais do Partido dos Trabalhadores para a Câmara dos Deputados no período de 1994 a 2014. Utilizando análise descritiva e modelos longitudinais com dados municipais, verificamos uma alteração dessas bases em direção a cidades com menor população e renda per capita mais baixa, localizadas, sobretudo, no Nordeste brasileiro. Demonstramos que as bases eleitorais do PT para a Câmara sofreram mudanças seme…
Mais Participação, Maior Responsividade? As Conferências Nacionais de Políticas Públicas e a Qualidade da Democracia no Brasil
Indagando se inovações democráticas podem, ao aumentar a participação da sociedade, ampliar a qualidade da democracia, o artigo toma uma das dimensões desta, a responsividade, como objeto de investigação. Propondo um modelo analítico deste conceito em três níveis (impacto nas políticas públicas, congruência temática e multidimensionalidade da participação), o artigo busca examinar se as Conferências Nacionais de Políticas Públicas aumentaram (ou …
