Drawing on theoretical insights from the persuasion knowledge model (PKM), this study aims to propose and test a model that maps out the antecedents, process and consequences to explain how consumers process and respond to fake news about brands on Facebook.

Contextualizing the fake news about Coca-Cola’s recall of Dasani water, an online survey was conducted via Qualtrics with consumers in the USA (N  =  468). Data were analyzed using covariance-based structural equation modeling.

Results showed that self-efficacy and media trust significantly predicted consumers’ persuasion knowledge of the fake news. Persuasion knowledge of the fake news significantly influenced consumers’ perceived diagnosticity of the fake news and subsequent brand trust. Furthermore, persuasion knowledge of the fake news mediated the effects from self-efficacy on perceived diagnosticity of the fake news and brand trust, respectively.

This study contributes to the literature of brand management by examining how consumers process and respond to fake news about a brand. It also extends the persuasion knowledge model by applying it to the context of fake news about brands on social media, and incorporating antecedents (self-efficacy and media trust) and consequences (perceived diagnosticity and brand trust) of persuasion knowledge in this particular context. Practically, this study provides insights to key stakeholders of brands to better understand consumers’ information processing of fake news about brands on social media.

Health-related online fake news (HOFN) has become a major social problem. HOFN can lead to the spread of ineffective and even harmful remedies. The study aims to understand Internet users' responses to HOFN during the coronavirus (COVID-19) pandemic using the protective action decision model (PADM).

The authors collected pandemic severity data (regional number of confirmed cases) from government websites of the USA and China (Studies 1 and 2), search behavior from Google and Baidu search engines (Studies 1 and 2) and data regarding trust in two online fake news stories from two national surveys (Studies 2 and 3). All data were analyzed using a multi-level linear model.

The research detected negative time-lagged relationships between pandemic severity and regional HOFN search behavior by three actual fake news stories from the USA and China (Study 1). Importantly, trust in HOFN served as a mediator in the time-lagged relationship between pandemic severity and search behavior (Study 2). Additionally, the relationship between pandemic severity and trust in HOFN varied according to individuals' perceived control (Study 3).

The authors' results underscore the important role of PADM in understanding Internet users' trust in and search for HOFN. When people trust HOFN, they may seek more information to implement further protective actions. Importantly, it appears that trust in HOFN varies with environmental cues (regional pandemic severity) and with individuals' perceived control, providing insight into developing coping strategies during a pandemic.

Climate change is major global policy issue. The news media play a vital role in conveying information about climate change to the public, giving voice to a variety of perspectives as well as outlining policy responses to this issue. However, the growing distrust of news media could lead to dire outcomes on the public's knowledge and policy support related to climate change. This paper uses a mixed method approach (random digit dialing survey, content analysis of newspaper articles) to examine information sources used in learning about climate change, whose voices are presented in climate change discourse, and whose voices are trusted. While news media are the most popular source of information about climate change (n=1207), only half of respondents reported trusting the news media. Scientists are the most trusted source of information (n=1208) and most cited source in news coverage (n=48). Their messages focus on the sources of climate change and the seriousness of this problem. Scientists' messages about climate change are clouded by high levels of distrust in the news media, the primary venue through which their messages are conveyed. In this context, climate change knowledge, level of concern, and support for public policies may suffer.

Television has long been cited by viewers as their primary and most trusted source of news, especially in relation to news of national and international affairs. Aims to explore the issue of trust in the television news.

The paper combines narrative and analysis. Questions whether public trust in the BBC was damaged by the Hutton inquiry: would the BBC's reputation as the nation's premier news service be tarnished in the longer‐term and had public trust in journalism been severely compromised.

Events that followed the transmission of a report about the veracity of the government's case for going to war carried by a BBC radio news broadcast on 29 May 2003 called into question the Corporation's competence as a reliable news provider. The story alleged that an informed source had told BBC correspondent Andrew Gilligan that the government had exaggerated the immediacy of dangers posed to the west by Saddam Hussein's weapons of mass destruction. The source who was eventually exposed was a Ministry of Defence expert on Iraq, Dr David Kelly, who later killed himself. The Prime Minister ordered a public inquiry into Dr Kelly's death, led by Lord Hutton, who severely criticised the competence of the BBC's senior management and the quality of its journalism practices. These conclusions prompted the resignation of the Corporation's Chairman and Director General. Hutton's findings had wider implications for the future governance of the BBC and invoked far‐reaching questions about the trust that the public could place in journalism. The evidence indicates that while the public felt that the BBC had been culpable for failing to launch its own internal inquiry into the Gilligan report, the public perceived this incident as a one‐off aberration rather than as being symptomatic of some wider malaise. Indeed, the Hutton inquiry had impacted more upon public trust in the government and led people to question the independence of the Hutton inquiry.

While trust in journalists is far from universal, the public differentiate among journalists in terms of the news organisations they work for. Among these, the BBC remains one of the most widely trusted.

An exploration of the issue of trust in the television news following the Dr David Kelly/Andrew Gilligan report on “The Today Programme” and subsequent Hutton enquiry.

The purpose of this paper is to examine the emergence of blogging in the news sphere. If blogs represent a genuinely new breed of news provision, then they should adhere to some of the founding principles of mainstream news and journalism. A key principle in this respect is news credibitility.

This paper presents a review of recent literature about news blogging and assesses whether news blogs manifest many of the core attributes of mainstream news and journalism. The review considers the attributes that have previously been identified as defining good quality news and competent journalism and then applies some of these principles to “news” blogging.

There is no doubt that blogs have emerged as news sources of increasing significance and there have been occasions when they can be influential in setting news agendas. The essential qualities of credibitiltiy and capturing public trust in the news sphere, however, often depends upon the established reputation of known news “brands”. Although some blogs have emerged as reliable information sources in some specialist areas, they have yet generally to assume the key characteristics of mainstream news that drive public trust.

This paper provides an up‐to‐date review of a topic that is rapidly developing and attempts to set out some foundations on which further analysis of news blogging can be constructed.

During the past few years, the rise in social media use for information purposes in the absence of adequate control mechanisms has led to growing concerns about the reliability of the information in circulation and increased the presence of fake news. While this topic has recently gained researchers' attention, very little is known about users' fake news identification behavior. Hence, the purpose of this study is to understand the factors that contribute to individuals' identification of fake news on social media.

This study employs a quantitative approach and proposes a behavioral model that explores the factors influencing users' identification of fake news on social media. It relies on data collected from a sample of 211 social media users which is tested using SEM.

The findings show that expertise in social media use and verification behavior have a positive impact on fake news identification, while trust in social media as an information channel decreases this identification behavior. Furthermore, results establish the mediating role of social media information trust and verification behavior.

The present study enhances our understanding of social media users' fake news identification by presenting a behavioral model. It is one of the few that focuses on the individual and argues that by identifying the factors that reinforce users' fake news identification behavior on social media, this type of misinformation can be reduced. It offers several theoretical and practical contributions.

Fact-checking is a process of seeking and displaying facts to confirm or counter uncertain information, which reduces the spread of fake news. However, little is known about how to promote fact-checking posts to online users on social media. Through uncertainty reduction theory and message framing, this first study examines the effect of fact-checking posts on social media with an avatar on online users' trust, attitudes, and behavioral intentions. The authors further investigate the congruency effects between promotional message framing (gain/loss/neutral) and facial expressions of the avatar (happy/angry/neutral) on online users' trust, attitudes, and behavioral intentions in the second study.

The authors conducted two studies and statistically analyzed 120 samples (study 1) and 519 samples (study 2) from Facebook users.

Results showed that including the neutral facial expression avatar in fact-checking posts leads to online users' greater trust and more positive attitudes. Furthermore, the congruency effects between loss message framing and the angry facial expression of the avatar can effectively promote online users' trust and attitudes as well as stronger intentions to follow and share.

This study offers theoretical implications for fact-checking studies, and practical implications for online fact-checkers to apply these findings to design effective fact-checking posts and spread the veracity of information on social media.

This study examines a controversial issue (biotechnology) and how news disputes about misinformation related to the issue impacts individuals' attitudes toward a biotechnology company and their trust in the media source.

This study conducts a 2 (risk: low vs. high) x 2 (pre-existing attitude: anti gene-editing technology vs. pro gene-editing technology) x 2 (dispute message: absent vs. present) x 2 (media source: Buzzfeed vs NYT) factorial online experiment using a Qualtrics panel (N = 1,080) to examine the impact on individuals' attitudes toward a biotechnology company and trust in the media source.

Results indicate that dispute messages enhance attitudes toward the company but decrease trust in media sources. Interaction effects between pre-existing attitude and the dispute message, along with perceived risk and the dispute message, illustrate stark differences in how individuals with favorable vs. unfavorable pre-existing attitudes assessed the company after viewing the dispute message.

This study applies arguments from extant literature about prebunking and debunking misinformation. Specifically, this study investigates how dispute messages, a form of debunking through source derogation, actually impact individuals' perceptions of media credibility and/or their attitudes about the content they are reading. The study findings also reveal new insights regarding the interaction between pre-existing attitudes and perceived risk, as well as how dispute messages interact with each of the aforementioned factors.

The authors sought to unpack the paradox between increasing demand for probiotics products against inconclusive scientific evidence about the effectiveness. This paper investigated public understanding of the composition and benefits of probiotic products, measured trust in news media and scientists as sources of information about probiotic products and informational and attitudinal predictors of consumer trust in the news media and scientists.

A cross-sectional survey was conducted amongst a representative sample of 2000 UK consumers. Participants responded to multiple-choice questions and psychometric scales capturing probiotics knowledge, consumption, information seeking behaviour, attitudes to and confidence in the news media and probiotics scientists. Descriptive statistics, one-way ANOVA and hierarchical regression modelling were performed.

Information exposure to probiotics content was highest from traditional media followed by online channels. Levels of confidence in probiotics scientists were higher than in the news media, even though these levels were highest amongst current consumers and lowest amongst non-consumers. Conflicting information, health consciousness and trust in nutrition stakeholders were identified as important predictors of trust in news media and scientists.

This study provides a large-scale nationally representative overview of public attitudes and sentiments related to probiotic products with a focus on attitudes towards the news media and the scientific establishment. The findings suggest a need for better consumer awareness about the state of science around probiotic products, interventions that could enable consumers to discern conflicting evidence or news reports, and critical skills that can render them more resilient to online misinformation.
