Given growing interest in the potential importance of news literacy around the world, a theoretically grounded and empirically validated measure of news literacy is essential. Building on existing theory, we developed and validated a 15-item true/false measure of news literacy knowledge. This measure comprehensively operationalizes the five C’s of...
Gen Z-ers around the world have grown up and come of age in a period rife with the implications of climate change, heightened rightwing extremism, threats to democracy, and rising inflation. Gen Z has also been characterized by an enhanced awareness of mental health care and body positivity, LGBTQIA+ and the spectrum of gender identity, as well as...
In the US and much of the developed world, Gen Z faces significant challenges such as climate change, racial inequality, and economic precarity. Though this emerging generation faces significant challenges, digital media is invaluable for engaging with public life. In this chapter, we will focus on changing civic identities of citizens in industria...
Prior to the COVID-19 pandemic, the World Health Organization named vaccine hesitancy as one of the top 10 threats to global health. The impact of hesitancy on the uptake of human papillomavirus (HPV) vaccines was of particular concern, given the markedly lower uptake compared to other adolescent vaccines in some countries, notably the United State...
With the ever-increasing spread of misinformation on online social networks, it has become very important to identify the spreaders of misinformation (unintentional), disinformation (intentional), and misinformation refutation. It can help in educating the first, stopping the second, and soliciting the help of the third category, respectively, in t...

Recent intense fire seasons in Australia, Borneo, South America, Africa, Siberia, and western North America have displaced large numbers of people, burned tens of millions of hectares, and generated societal urgency to address the wildfire problem (Bowman et al. 2020). Nearly all terrestrial ecosystems, however, burn with some degree of regularity,...
This study expands on existing research about correcting misinformation on social media. Using an experimental design, we explore the effects of three truth signals related to stories shared on social media: whether the person posting the story says it is true, whether the replies to the story say it is true, or whether the story itself is actually...
Misinformation about climate change is a consequential societal issue, causing polarization and reduced support for climate action. However, the seriousness of the problem does not preclude non-serious solutions. There are numerous potential benefits to humor as a strategy to counter misinformation, such as attracting attention and engaging disenga...
Political campaigns often feature jarring revelations against candidates. This study examines how audiences come to understand major campaign events, the extent to which they shape evaluations of candidates, and how their impact is filtered through an increasingly partisan news media environment. Using national rolling cross-sectional survey data c...
Misinformation has been identified as a major contributor to various contentious contemporary events ranging from elections and referenda to the response to the COVID-19 pandemic. Not only can belief in misinformation lead to poor judgements and decision-making, it also exerts a lingering influence on people’s reasoning after it has been corrected...
The World Health Organization declared the deluge of publicly available information about COVID-19 to be an “infodemic,” comprising both facts and misinformation. Researchers don’t know exactly the degree to which people believe the misinformation they see online, but, in the case of COVID-19, belief in conspiracy theories related to the virus is a...
Although correction is often suggested as a tool against misinformation, and empirical research suggests it can be an effective one, we know little about how people perceive the act of correcting people on social media. This study measures such perceptions in the context of the onset of the COVID-19 pandemic in 2020, introducing the concept of valu...
Given concerns about the persuasive power of video misinformation on social media for health topics, we test two techniques – exposure to a news literacy video and user corrections – to limit the effects on misperceptions. An online sample of American adults from August of 2019 was randomly assigned to view two simulated Facebook videos. The first...
Despite a wealth of research examining the effectiveness of correction of misinformation, not enough is known about how people experience such correction when it occurs on social media. Using a study of US adults in late March 2020, we measure how often people witness correction, correct others, or are corrected themselves, using the case of COVID-...
Interest in news literacy inside and outside the academy has grown alongside related concerns about the quality of news and information available. Attempts to fully define, explicate and operationalize news literacy, however, are scattered. Drawing on literature across journalism and mass communication, we propose a definition of news literacy that...
Extending previous research, we test two solutions for addressing misinformation by pairing news literacy (NL) messages with corrective responses to health misinformation shared on Twitter. Importantly, we consider a range of outcomes, including not just credibility or misperceptions, but also feelings of news literacy and support for its value. Us...
As COVID-19 vaccines become available to the public, there will be a massive worldwide distribution effort. Vaccine distribution has historically been unequal primarily due to the inability of nations with developing economies to purchase enough vaccine to fully vaccinate their populations. Inequitable access to COVID-19 vaccines will not just caus...
Efforts to address misinformation on social media have special urgency with the emergence of coronavirus disease (COVID-19). In one effort, the World Health Organization (WHO) designed and publicized shareable infographics to debunk coronavirus myths. We used an experiment to test the efficacy of these infographics, depending on placement and sourc...
We experimentally test whether expert organizations on social media can correct misperceptions of the scientific consensus on the safety of genetically modified (GM) food for human consumption, as well as what role social media cues, in the form of “likes,” play in that process. We find expert organizations highlighting scientific consensus on GM f...
This article investigates the prevalence of high and low quality URLs shared on Twitter when users discuss COVID-19. We distinguish between high quality health sources, traditional news sources, and low quality misinformation sources. We find that misinformation, in terms of tweets containing URLs from low quality misinformation websites, is shared...
Background
This study assessed psychosocial predictors of U.S. adults’ willingness to get a future COVID-19 vaccine and whether these predictors differ under an emergency use authorization (EUA) release of the vaccine.
Methods
A survey of 788 U.S. adults was conducted to explore the relationships between demographics and psychosocial predictors of...
Objectives. To compare how human papillomavirus (HPV) vaccination was portrayed on Pinterest before and after the platform acted to moderate vaccine-related search results to understand (1) what the information environment looked like previously and (2) whether Pinterest’s policy decisions improved this environment in terms of sources and content....
Misinformation spreads on social media when users engage with it, but users can also respond to correct it. Using an experimental design, we examine how exposure to misinformation and correction on Twitter about unpasteurized milk affects participants’ likelihood of responding to the misinformation, and we code open-ended responses to see what part...
An emerging infectious disease event like the coronavirus (COVID‐19) pandemic demands careful communication of public health messages to diverse audiences. However, misinformation is easily generated and amplified when a rapidly evolving epidemiological situation is coupled with gaps in scientific knowledge about a novel pathogen. Groups involved i...
This study uses an unobtrusive eye tracking approach to examine understudied psychological mechanisms – message attention and credibility – when people are exposed to misinformation and correction on social media. We contrast humor versus non-humor correction strategies that point out rhetorical flaws in misinformation regarding the HPV vaccine, wh...
Despite renewed interest in news literacy (NL) as a way to combat mis- and dis-information, existing scholarship is plagued by insufficient theory building and inadequate conceptualization of both “NL” and its application. We address this concern by offering a concise definition of NL and suggest five key knowledge and skill domains that comprise t...
The World Health Organization has declared that misinformation shared on social media about Covid-19 is an “infodemic” that must be fought alongside the pandemic itself. We reflect on how news literacy and science literacy can provide a foundation to combat misinformation about Covid-19 by giving social media users the tools to identify, consume, a...
Despite concerns about misinformation across social media platforms, little attention has been paid to how to correct misinformation on visual platforms like Instagram. This study uses an experimental design on a national sample to test two features of user-based correction strategies on Instagram for a divisive issue on which misinformation abound...
A by-product of today’s hybrid media system is that genres—once uniformly defined and enforced—are now murky and contested. We develop the concept of news-ness, defined as the extent to which audiences characterize specific content as news, to capture how audiences understand and process media messages. In this article, we (a) ground the concept of...
Since December 2019, COVID-19 has been spreading rapidly across the world. Not surprisingly, conversation about COVID-19 is also increasing. This article is a first look at the amount of conversation taking place on social media, specifically Twitter, with respect to COVID-19, the themes of discussion, where the discussion is emerging from, myths s...

When is a tweet considered news? This study uses an experimental design to isolate two features of a headline shared on Twitter to determine the impact on audience ratings of ‘news-ness.’ We examine how people rate a Twitter post about potential government shutdown depending on: the type of story headline (breaking, exclusive, fact check, opinion),...
A number of solutions have been proposed to address concerns about misinformation online, including encouraging experts to engage in corrections of misinformation being shared and improving media literacy among the American public. This study combines these approaches to examine whether news literacy (NL) messages on social media enhance the effect...
Amid growing concerns about misinformation on social media, scholars, educators, and commentators see news literacy as a means to improve critical media consumption. We use a nationally-representative sample to investigate the relationship between news literacy (NL), seeing and posting news and political content on social media, and skepticism towa...
Misinformation causes a range of negative impacts. One proposed solution is applying critical thinking techniques to neutralize misinformation by explaining its misleading techniques or logical fallacies. This study tests the efficacy of corrections after exposure to misinformation that adopt inoculating techniques. We test two forms of rhetorical...
The question of how to measure exposure to different types of content on social media grows in importance with increased use of these platforms. Social media further complicate this task by bringing diverse content into the same space, raising the question of whether selective exposure or incidental exposure theories best explain attention patterns...
As concerns grow about the spread of misinformation through social media, scholars have called for improving the public’s media literacy as a potential solution. This study examines the effectiveness of deploying news literacy (NL) messages on social media by testing whether NL tweets are able to affect perceptions of information credibility and NL...
The increased reliance on social network sites for news and the proliferation of partisan news have refocused scholarly attention on how people judge credibility online. Twitter has faced scrutiny regarding their practices in assigning the "verified" status to Twitter accounts, but little work has investigated whether users apply this cue in making...
We examined whether news media literacy (NML) messages attenuate selective exposure and avoidance. One week before the 2016 U.S. presidential election, participants were randomly assigned to see a NML video advertisement before entering a simulated news aggregation website where behaviors were unobtrusively tracked. For three of the four NML messag...

Despite the importance of news exposure to political outcomes, news consumption is notoriously difficult to measure, and misreporting news exposure is common. In this study, we compare participants’ news behaviors measured on a news aggregator website with their self-reported story selection immediately after exposure. We find that both individual...
Drawing on interviews with a diverse group of adults living in the United States, this study examines news media literacy and how perceptions of personal bias and news bias affect news choices and interpretation in general and evaluation of two news stories specifically. Findings suggest that while people recognize that their worldviews shape their...
How do different types of host partisanship affect viewers of political talk shows? An experiment replicated on 2 age cohorts examines how different manifestations of partisanship in the cable news environment —explicit partisanship in which the host makes clear his views, and implicit partisanship in which the host gives more time to the guest on...
Ideologically motivated rejection of scientific evidence can be harmful to individuals and society, especially regarding consequential issues like climate change. A growing base of evidence suggests a cognitive style known as Actively Open-Minded Thinking (AOT) may reduce ideological rejection of scientific findings. In this article, we test the as...

Many scientists communicate with the public about risks associated with scientific issues, but such communication may have unintended consequences for how the public views the political orientations and the credibility of the communicating scientist. We explore this possibility using an experiment with a nationally representative sample of American...
Social media are often heralded as offering cancer campaigns new opportunities to reach the public. However, these campaigns may not be equally successful, depending on the nature of the campaign itself, the type of cancer being addressed, and the social media platform being examined. This study is the first to compare social media activity on Twit...
Cancer awareness campaigns compete with other health and social issues for public attention. We examined whether public engagement with breast cancer and prostate cancer declined in 2016 during the U.S. presidential election compared to 2015 on Twitter and Google Trends. We found that attention to breast cancer and prostate cancer declined in 2016...
In this article, we focus on the potential influence of a scientist’s advocacy position on the public’s perceived credibility of scientists as a whole. Further, we examine how the scientist’s solution position (information only, non-controversial, and controversial) affects the public’s perception of the scientist’s motivation for sharing informati...

This study tests whether the number (1 vs. 2) and the source (another user vs. the Centers for Disease Control and Prevention [CDC]) of corrective responses affect successful reduction of misperceptions. Using an experimental design, our results suggest that while a single correction from another user did not reduce misperceptions, the CDC on its o...
This study uses two experimental designs to examine how audiences make genre assessments when encountering media content that blends elements of news and entertainment. Study 1 explores how audiences characterize three different versions of a fictitious political talk show program. Study 2 considers whether audience perceptions of ‘news-ness’ are i...
High quality cross-platform research is difficult and expensive to perform in political communication. Yet studying media platforms in isolation ignores the realities of the contemporary media experience. As platforms multiply, the media environment itself has become more complicated, as classic understandings of media ecology give way to a growing...
This study extends past research on the relationship between news use and participation by examining how youth combine news exposure across an array of media devices, sources, and services. Results from a national survey of U.S. youth ages 12 to 17 reveal four distinct news repertoires. We find that half of youth respondents are news avoiders who e...
Social media are often criticized for being a conduit for misinformation on global health issues, but may also serve as a corrective to false information. To investigate this possibility, an experiment was conducted exposing users to a simulated Facebook News Feed featuring misinformation and different correction mechanisms (one in which news stori...
Developing news media literacy skills is recognized as an important part of becoming an informed citizen, but not enough research examines how growth in media literacy differs by individual characteristics. Using a panel study of undergraduate students, we examine which predispositions predict growth in news media literacy beliefs over the semester...
Background: The recent Zika outbreak witnessed the disease evolving from a regional health concern to a global epidemic. During this process, different communities across the globe became involved in Twitter, discussing the disease and key issues associated with it. This paper presents a study of this discussion in Twitter, at the nexus of location...
Social media are often criticized as serving as a source of misinformation, but in this study we examine how they may also function to correct misperceptions on an emerging health issue. We use an experimental design to consider social correction that occurs via peers, testing both the type of correction (i.e., whether a source is provided or not)...
Selective exposure is a growing concern as people become more reliant on social media for political information. While self-reports often ask about exposure to political content on social media, existing research does not account for the fact that even those exposed to political content may still choose to ignore it. To effectively account for this...
It is often assumed that issue advocacy will compromise the credibility of scientists. We conducted a randomized controlled experiment to test public reactions to six different advocacy statements made by a scientist—ranging from a purely informational statement to an endorsement of specific policies. We found that perceived credibility of the comm...
As approval ratings of the U.S. Congress remain depressed, many candidates present themselves as mavericks, willing to counter their party on issues. Yet disagreeing with one's party can be a risky decision and one that is not equally viable for all politicians. In particular, female candidates often face a hostile political climate that privileges...
This study seeks to understand how American youth (aged 12–17 years) learn to consume the news, with specific concern for which devices (television, computer, tablet, and mobile phone) they employ in consuming news. Using a national survey of parent–child dyads, we explore (1) the role of demographics in creating a home environment supportive of ne...
Moving media literacy messages out of the classroom and onto the Internet, where much news consumption happens, offers an opportunity to extend media literacy education to a wider public. However, in doing so it becomes important to consider how the context in which such messages are seen conditions their impact on media literacy attitudes and know...
Purpose
Social networking sites (SNS) increasingly serve as a source of political content for Americans. The purpose of this paper is to clarify the relationships between types of political content exposure, especially congruent vs incongruent content, and its effects on political expression and participation. This study pays special attention to w...
In an evolving news environment, our understanding and application of ?news media literacy? must also evolve to equip individuals with the skills to critically engage with news and participate in public life. Using an experimental design, this study tests different news media literacy messages to determine whether certain messages appeal to some gr...
Research on social media content overwhelmingly relies on self-reports, which we suggest are meaningfully limited and likely biased. Instead, we apply an under-utilized method—corneal eye tracking—for gauging attention to content in social media. We expose subjects to different types of Facebook content and track their gaze as they browse through p...
While a growing body of literature examines exposure to social, news, and political information via social media, we have little understanding of how users delineate these categories. In this study, we develop over 100 discrete Facebook stimuli varying these topics, and then test to what extent and which users match our definition of those posts. O...
