From Participatory Experiments to Democratic Infrastructure
Carolyn Lukensmeyer's apt observations about Engaged California, BG2050, and the Fort Collins citizens' assembly prove that, when given the chance, ordinary citizens can enrich the quality and legitimacy of the policy process. We share her enthusiasm but draw different conclusions about priorities, if not ultimate goals. Lukensmeyer's emphasis is on continuing these sorts of experiments and moving them from cities to states to the national level.…
Complex Contagion in Social Networks
Complex contagion rests on the idea that individuals are more likely to adopt a behavior if they experience social reinforcement from multiple sources. We develop a test for complex contagion, conceptualized as social reinforcement, and then use it to examine whether empirical data from a country-scale randomized controlled viral marketing field experiment show evidence of complex contagion. The experiment uses a peer encouragement design in whic…
Continuity and Change in Trust in Scientists in the United States
Americans’ trust in scientists has been stable and high, relative to other political and social institutions, for the last half century (Krause, Brossard, and Scheufele 2019). Yet, underlying this stability lies a dramatic change such that a partisan gap has emerged, with Democrats exhibiting substantially more trust than Republicans. Fifty years ago, Republicans in fact exhibited more relative trust in scientists. This article explains this cont…
Depression, Populism, and Presidential Approval
Is there a relationship between depression and political evaluations? Building on existing work, we argue that experiencing depressive symptoms will positively correlate with supporting a populist politician and negatively correlate with supporting a nonpopulist officeholder. We evaluate these predictions with data from the United States, focusing on Donald Trump and Joe Biden. Our data are consistent with our hypotheses, and, as expected, we fin…
Using co-sharing to identify use of mainstream news for promoting potentially misleading narratives
Much of the research quantifying volume and spread of online misinformation measures the construct at the source level, identifying a set of specific unreliable domains that account for a relatively small share of news consumption. This source-level dichotomy obscures the potential for users to repurpose factually true information from reliable sources to advance misleading narratives. We demonstrate this potentially far more prevalent form of mi…
Curation Bubbles
Information on social media is characterized by networked curation processes in which users select other users from whom to receive information, and those users in turn share information that promotes their identities and interests. We argue this allows for partisan "curation bubbles" of users who share and consume content with consistent appeal drawn from a variety of sources. Yet, research concerning the extent of filter bubbles, echo chambers,…
A Normative Framework for Assessing the Information Curation Algorithms of the Internet
It is critical to understand how algorithms structure the information people see and how those algorithms support or undermine society’s core values. We offer a normative framework for the assessment of the information curation algorithms that determine much of what people see on the internet. The framework presents two levels of assessment: one for individual-level effects and another for systemic effects. With regard to individual-level effects…
The Diffusion and Reach of (Mis)Information on Facebook during the U.S. 2020 Election
Social media creates the possibility for rapid, viral spread of content, but how many posts actually reach millions? And is misinformation special in how it propagates? We answer these questions by analyzing the virality of and exposure to information on Facebook during the U.S. 2020 presidential election. We examine the diffusion trees of the approximately 1 B posts that were re-shared at least once by U.S.-based adults from July 1, 2020, to Feb…
Covid-19 Spillover Effects onto General Vaccine Attitudes
Even amid the unprecedented public health challenges attributable to the COVID-19 pandemic, opposition to vaccinating against the novel coronavirus has been both prevalent and politically contentious in American public life. In this paper, we theorize that attitudes toward COVID-19 vaccination might “spill over” to shape attitudes toward “postpandemic” vaccination programs and policy mandates for years to come. We find this to be the case using e…
Pathways of Peer Influence on Major Choice
Peers influence students' academic decisions and outcomes. For example, several studies with strong claims to causality demonstrate that peers affect the choice of and persistence in majors. One remaining issue, however, has stymied efforts to translate this evidence into actionable interventions: the literature has not grappled adequately with the fact that in natural settings, students typically select most of their peers. The bulk of causal ev…
Like-minded sources on Facebook are prevalent but not polarizing
Many critics raise concerns about the prevalence of ‘echo chambers’ on social media and their potential role in increasing political polarization. However, the lack of available data and the challenges of conducting large-scale field experiments have made it difficult to assess the scope of the problem 1,2 . Here we present data from 2020 for the entire population of active adult Facebook users in the USA showing that content from ‘like-minded’ s…
Asymmetric ideological segregation in exposure to political news on Facebook
Does Facebook enable ideological segregation in political news consumption? We analyzed exposure to news during the US 2020 election using aggregated data for 208 million US Facebook users. We compared the inventory of all political news that users could have seen in their feeds with the information that they saw (after algorithmic curation) and the information with which they engaged. We show that (i) ideological segregation is high and increase…
How do social media feed algorithms affect attitudes and behavior in an election campaign?
We investigated the effects of Facebook’s and Instagram’s feed algorithms during the 2020 US election. We assigned a sample of consenting users to reverse-chronologically-ordered feeds instead of the default algorithms. Moving users out of algorithmic feeds substantially decreased the time they spent on the platforms and their activity. The chronological feed also affected exposure to content: The amount of political and untrustworthy content the…
Misinformation, Trust, and Use of Ivermectin and Hydroxychloroquine for Covid-19
In this survey study of US adults, endorsement of misinformation about the COVID-19 pandemic, lack of trust in physicians or scientists, conspiracy-mindedness, and the nature of news sources were associated with receiving non-evidence-based treatment for COVID-19. These results suggest that the potential harms of misinformation may extend to the use of ineffective and potentially toxic treatments in addition to avoidance of health-promoting behav…
Categorizing the non-categorical
Studies of gendered phenomena online have highlighted important disparities, such as who is likely to be elevated as an expert or face gender-based harassment. This research, however, typically relies upon inferring user gender—an act that perpetuates notions of gender as an easily observable, binary construct. Motivated by work in gender and queer studies, we therefore compare common approaches to gender inference in the context of online settin…
Using General Messages to Persuade on a Politicized Scientific Issue
Politics and science have become increasingly intertwined. Salient scientific issues, such as climate change, evolution, and stem-cell research, become politicized, pitting partisans against one another. This creates a challenge of how to effectively communicate on such issues. Recent work emphasizes the need for tailored messages to specific groups. Here, we focus on whether generalized messages also can matter. We do so in the context of a high…
Reducing Health Misinformation in Science
The public often turns to science for accurate health information, which, in an ideal world, would be error free. However, limitations of scientific institutions and scientific processes can sometimes amplify misinformation and disinformation. The current review examines four mechanisms through which this occurs: (1) predatory journals that accept publications for monetary gain but do not engage in rigorous peer review; (2) pseudoscientists who p…
The role of race, religion, and partisanship in misperceptions about Covid-19
Concerns about misperceptions among the public are rampant. Yet, little work explores the correlates of misperceptions in varying contexts – that is, how do factors such as group affiliations, media exposure, and lived experiences correlate with the number of misperceptions people hold? We address these questions by investigating misperceptions about COVID-19, focusing on the role of racial/ethnic, religious, and partisan groups. Using a large su…
Bigbirds Never Die
We examine the growth, survival, and context of 256 novel hashtags during the 2012 U.S. presidential debates. Our analysis reveals the trajectories of hashtag use fall into two distinct classes: "winners" that emerge more quickly and are sustained for longer periods of time than other "also-rans" hashtags. We propose a "conversational vibrancy" framework to capture dynamics of hashtags based on their topicality, interactivity, diversity, and prom…
Using Administrative Records and Survey Data to Construct Samples of Tweeters and Tweets
Social media data can provide new insights into political phenomena, but users do not always represent people, posts and accounts are not typically linked to demographic variables for use as statistical controls or in subgroup comparisons, and activities on social media can be difficult to interpret. For data scientists, adding demographic variables and comparisons to closed-ended survey responses have the potential to improve interpretations of …
Demographics and (Equal?) Voice
Critics of deliberative democracy have worried that deliberation may mirror (or even exacerbate) inequalities in participation across categories such as gender, race, and age. Accordingly, we investigate the potential for technology and design to ameliorate these concerns, looking at the extent to which online deliberative sessions facilitate inclusive participation. In a large study of online deliberation (over 1600 participants nested in hundre…
Sustained Online Amplification of Covid-19 Elites in the United States
In the absence of clear, consistent guidelines about the COVID-19 pandemic in the United States, many people use social media to learn about the virus, public health directives, vaccine distribution, and other health information. As people individually sift through a flood of information online, they collectively curate a small set of accounts, known as crowdsourced elites, that receive disproportionate attention for their COVID-19 content. Howev…
Public Health and Online Misinformation
The internet has become a popular resource to learn about health and to investigate one's own health condition. However, given the large amount of inaccurate information online, people can easily become misinformed. Individuals have always obtained information from outside the formal health care system, so how has the internet changed people's engagement with health information? This review explores how individuals interact with health misinforma…
Searching for the backfire effect
their belief in the very misconception the correction is aiming to rectify. There is currently a debate in the literature as to whether backfire effects exist at all, as recent studies have failed to find the phenomenon, even under theoretically favorable conditions. In this review, we summarize the current state of the worldview and familiarity backfire effect literatures. We subsequently examine barriers to measuring the backfire phenomenon, di…
Misinformation in action
One major concern about fake news is that it could damage the public trust in democratic institutions. We examined this possibility using longitudinal survey data combined with records of online behavior. Our study found that online misinformation was linked to lower trust in mainstream media across party lines. However, for moderates and conservatives, exposure to
Who Wants To Deliberate-And Why
Interest in deliberative theories of democracy has grown tremendously among political theorists, political scientists, activists, and even government officials. Many scholars, however, are skeptical that it is a practically viable theory, even on its own terms. They argue(inter alia)that most people dislike politics and that deliberative initiatives would amount to a paternalistic imposition. Using two large national samples investigating people'…
The Coevolution of Networks and Political Attitudes
How do attitudes and social affiliations coevolve? A long stream of research has focused on the relationship between attitudes and social affiliations. However, in most of this research the causal relationship between views and affiliations is difficult to discern definitively: Do people influence each other's views so that they converge over time or do they primarily affiliate (by choice or happenstance) with those of similar views? Here we use …
Management-Based Regulation
We analyze a little-studied regulatory approach that we call management-based regulation. Management-based regulation directs regulated organizations to engage in a planning process that aims toward the achievement of public goals, offering firms flexibility in how they achieve public goals. In this article, we develop a framework for assessing conditions for using management-based regulation as opposed to the more traditional technology-based or…
Friends, Brokers, and Transitivity
Why and how do groups share information in politics? Most studies of information exchange in politics focus on individual-level attributes and implicitly assume that communication between any two policy actors is independent of the larger communication network in which they are embedded. We develop a theory stating that the decision of any lobbyist to inform another lobbyist is heavily conditioned upon their mutual relationships to third parties.…
Data ex Machina
Social life increasingly occurs in digital environments and continues to be mediated by digital systems. Big data represents the data being generated by the digitization of social life, which we break down into three domains: digital life, digital traces, and digitalized life. We argue that there is enormous potential in using big data to study a variety of phenomena that remain difficult to observe. However, there are some recurring vulnerabilit…
The Strength of Weak Ties in Lobbying Networks
How does policy information flow through Washington `issue networks'? And how does information flow determine which lobbyists get access in policy-making? Drawing upon the `strength of weak ties' argument, the authors argue that policy information passes more through acquaintances (`weak ties') than through close, trusted, contacts (`strong ties'). They support this argument in an analysis of data on lobbying networks in health-care policy-making…

The Incidental Pundit
Informal discussion plays a crucial role in democracy, yet much of its value depends on diversity. We describe two models of political discussion. The purposive model holds that people typically select discussants who are knowledgeable and politically similar to them. The incidental model suggests that people talk politics for mostly idiosyncratic reasons, as by‐products of nonpolitical social processes. To adjudicate between these accounts, we d…
The co‐evolution of individual and network
Individuals simultaneously choose and are affected by their web of connections. This paper explores this co‐evolution of individual and network in the context of longitudinal attitudinal and sociometric data collected from a government agency, the Office of Information and Regulatory Affairs. Analysis of these data suggests that networks vary in their elasticity ‐ where the internal network of the agency was rigid, but the extra‐organizational ne…
Regulatory interdependence and international governance
The objective of this paper is threefold: First is to produce a broad framework of the ways that state regulatory policies are interdependent. Second is to examine the factors that determine the nature of that interdependence. Third is to discuss the governance implications of different types of regulatory interdependencies. This analysis is applied to the spread of a new international fish inspection regulatory regime. I propose three modes of r…
The Free Trade Epidemic of the 1860s and Other Outbreaks of Economic Discrimination
Why was there an abrupt increase in economic openness in Europe in the 1860s? This increase may have been the result of a contagion process, in which the Cobden-Chevalier treaty between Britain and France threatened to displace third-party exports to France with British exports. As a result, most European states signed similar treaties with France, which had further ripple effects.This article outlines a formal model of this process, based on the…
Regulatory Capitalism as a Networked Order
This article conceptualizes the international system as an informational network—where the sovereign units in the system produce and process information, and linkages among units in the system are conduits for information. Building on a substantial literature that documents the diffusion of policies across nations, this article draws on concepts from network analysis to ask a critical question: what governance issues are raised by viewing the int…

Searching for Answers
How do public administrators find information about the problems they confront at work? In particular, how and when do they reach across organizational boundaries to find answers? There are substantial potential obstacles to such searches for answers, especially in a system of decentralized governance such as the U.S. government. In this article, we examine the alternative mechanisms within the public sector that compensate for this dispersion of…
The Strength of Strong Ties
Interest groups establish contacts with each other as a way of gaining useful policy information, and in this article we develop and test a model to explain this political phenomenon. Our simulation model suggests that when few need information, groups will pursue an acquaintance strategy by investing time and resources in gaining `weak tie' political acquaintances rather than in gaining `strong tie' political friends, but that as the collective …
Networks in Political Science
What are the relational dimensions of politics? Does the way that people and organizations are connected to each other matter? Are our opinions affected by the people with whom we talk? Are legislators affected by lobbyists? Is the capacity of social movements to mobilize affected by the structure of societal networks? Powerful evidence in the literature answers each of these questions in the affirmative. However, compared to other paradigmatic f…

Estimating Treatment Effects in the Presence of Noncompliance and Nonresponse
If ignored, noncompliance with a treatment or nonresponse on outcome measures can bias estimates of treatment effects in a randomized experiment. To identify and estimate causal treatment effects in the case where compliance and response depend on unobservables, we propose the parametric generalized endogenous treatment (GET) model. GET incorporates behavioral responses within an experiment to measure each subject's latent compliance type and ide…

The social silos of journalism? Twitter, news media and partisan segregation
The present work proposes social media as a tool to understand the relationship between journalists’ social networks and the content they produce. Specifically, we ask, “what is the association between the partisan nature of the accounts journalists follow on Twitter and the news content they produce?” Using standard text scaling techniques, we analyze partisanship in a novel dataset of more than 300,000 news articles produced by 644 journalists …
Expanding the Conversation
Do formal deliberative events influence larger patterns of political discussion and public opinion? Critics argue that only a tiny number of people can participate in any given gathering and that deliberation may not remedy—and may in fact exacerbate—inequalities. We assess these criticisms with an experimental design merging a formal deliberative session with data on participants' social networks. We conducted a field experiment in which randoml…

Since adapting old practices to new technology entails uncertainty, the authors expect legislative offices to learn website representation practices from each other. Using data from the 2006 and 2007 official home pages of members of the U.S. House of Representatives, the authors find that web design practices regarding the content of legislative websites diffuse w…

Structure and tie strengths in mobile communication networks
Electronic databases, from phone to e-mails logs, currently provide detailed records of human communication patterns, offering novel avenues to map and explore the structure of social and communication networks. Here we examine the communication patterns of millions of mobile phone users, allowing us to simultaneously study the local and the global structure of a society-wide communication network. We observe a coupling between interaction streng…
Inferring friendship network structure by using mobile phone data
Data collected from mobile phones have the potential to provide insight into the relational dynamics of individuals. This paper compares observational data from mobile phones with standard self-report survey data. We find that the information from these two data sources is overlapping but distinct. For example, self-reports of physical proximity deviate from mobile phone records depending on the recency and salience of the interactions. We also d…

And this should especially be true for freshman members. We test th…
