Social-psychological factors influencing risk perceptions of chronic wasting disease on social media
Chronic wasting disease (CWD) is a prion-based disease that poses an imminent threat to New York State (NYS), but many NYS hunters do not perceive it as a salient issue or follow recommended practices to prevent its spread to NYS. This study sought to identify the social-psychological factors underlying the efficacy of social media interventions to increase risk perceptions of CWD in NYS. We conducted an online survey experiment with 2760 NYS hun…
Expanding on Behavioral Outcomes in the Risk Information Seeking and Processing Model: Socio-Cognitive Factors Predicting Information Seeking, Sharing, and Discussion
We employed the risk information seeking and processing (RISP) model to identify socio-cognitive factors motivating hunters’ information seeking, sharing, and discussion of the risks of using lead ammunition for hunting. Values, risk perceptions, and informational insufficiency similarly predicted individual- and societal-level informational behavioral intentions. In contrast, knowledge and explicated informational subjective norms (descriptive, …
The Evolving Field of Risk Communication
The 40th Anniversary of the Society for Risk Analysis presents an apt time to step back and review the field of risk communication. In this review, we first evaluate recent debates over the field's current state and future directions. Our takeaway is that efforts to settle on a single, generic version of what constitutes risk communication will be less productive than an open‐minded exploration of the multiple forms that comprise today's vibrant …
Predictors of intentions to conserve bats among New York property owners
Understanding why private property owners take actions to conserve bats has become increasingly important in U.S. states where the fungus causing white-nose syndrome (Pseudogymnoascus destructans) has decimated bat populations. We surveyed property owners in three New York State counties (n = 2,500) and used multiple linear regression analyses to test predictors of intentions to conserve bats. Intentions to take actions that contribute to bat con…
Covid-19: Reflections on trust, tradeoffs, and preparedness
The global coronavirus disease (COVID-19) pandemic has already had an enormous impact and will surely have profound consequences for many years to come. The authors reflect on three risk communication themes related to the pandemic: trust, tradeoffs, and preparedness. Trust is critically important during such a rapidly evolving event characterized by scientific uncertainty. Reflections focus on uncertainty communication, transparency, and long-te…
Scared Yet Compassionate? Exploring the Order Effects of Threat Versus Suffering Messages on Attitude Toward Scary Victims
The order in which individuals receive information about wildlife may influence their attitude toward wildlife differently. We explored order effects of a threat message that induced more fear versus a suffering message that elicited more compassion on attitude toward wildlife. Specifically, we focused on bats, a risk-laden species also suffering massive mortalities due to a disease affecting bat populations across the United States. We randomly …
Public understanding of One Health messages: The role of temporal framing
Building on research in motivated reasoning and framing in science communication, we examine how messages that vary attribution of responsibility (human vs animal) and temporal orientation (now vs in the next 10 years) for wildlife disease risk influence individuals’ conservation intentions. We conducted a randomized experiment with a nationally representative sample of US adults ( N = 355), which revealed that for people low in biospheric concer…
Source Effects on Psychological Reactance to Regulatory Policies: The Role of Trust and Similarity
Efforts to communicate risk reduction policies must consider how target audiences will respond to the source of the message. This study investigates how modifying the message source enhances or diminishes psychological reactance against a policy designed to curb a wildlife disease. In an experimental study, we attributed a press release announcing this policy to different sources. We found that the source had an indirect effect on reactance, whic…
Intersecting frames in communicating environmental risk and uncertainty
Risk scholars have long examined how public opinion about environmental issues is shaped by message framing devices, for example, as when climate change is portrayed as a ‘public health’ vs. ‘environmental health’ issue, or when the phenomenon itself is labeled as ‘global warming’ vs. ‘climate change.’ Yet, seldom do these framing devices occur in isolation; instead, they often co-occur – or intersect – in messaging about emerging environmental r…

The Influence of Unrestricted Information Exchange on Willingness to Share Information With Outsiders: Unrestricted Exchange and External Information Sharing
This study addressed how engaging in different forms of information exchange within a group is related to group members' willingness to share risk information with outsiders. Drawing from social exchange theories, we focused on 3 unrestricted forms of information exchange: pure-generalized, group-generalized, and productive. We hypothesized that individuals' intentions to share information with outsiders would be associated positively with engage…
Media’s Role in Enhancing Sustainable Development in Zambia
The dual pressures of climate change and population growth in Africa make enhancing sustainable development an important focus of initiatives hoping to reach as many people as possible with appropriate innovations. Resource and infrastructure challenges often limit the ability of programs to expand through the use of extension and other forms of in-person training. Although media such as radio, television, and mobile phones cannot replace the val…
Transparency in the food aisle: The influence of procedural justice on views about labeling GM foods
Issues of transparency lay at the center of the debate surrounding the labeling of genetically modified (GM) food products in the USA. These issues include not only the argument that consumers should be allowed to make purchasing choices based on full disclosure of product ingredients but also that they should have access to the process that makes decisions about labeling. This study examines the influence of procedural justice on perceived decis…

How Motivated Reasoning and Temporal Frames May Polarize Opinions About Wildlife Disease Risk
We draw from theories of motivated reasoning, dual-processing models, and attribution of responsibility to examine how scientific messages may increase public polarization with respect to emerging risk issues such as Lyme disease. A nationally representative sample of Americans ( N = 460) read messages about Lyme disease that varied the framing of responsibility for the prevalence of the disease (human/wildlife vs. wildlife only) and when its eff…

Perspective on ‘Four Questions for Risk Communication’
In his essay, ‘Four Questions for Risk Communication, ’ Roger Kasperson challenges the risk communication community to take better stock of the lessons it’s learned over the past several decades. Implicated are the failure of many to reap the rewards or benefits of our field’s discoveries and the attendant responsibility we collectively bear in not communicating them well enough. Less a scolding than a call to action, Kasperson thoughtfully refle…
Something old and something new: Comparing views about nanotechnology and nuclear energy
Much discussion surrounds the question of whether people tend to perceive new and emerging technologies in ways similar to how they perceive older, more familiar technologies. The study argues that the direct association between familiarity and support is just one way of thinking about how familiarity may affect views about emerging technologies, such as nanotechnology and nuclear energy. The study uses a probability-based survey of Americans whe…

Exploring risk attenuation and crisis communication after a plague death in Grand Canyon
In 2007, a US National Park Service (NPS) biologist working in Grand Canyon National Park in the state of Arizona died from pneumonic plague contracted from a mountain lion, prompting NPS, in partnership with local and federal agencies, to inform publics about plague risk within park contexts. Overall, the incident attracted limited media attention and public concern about an increased risk of plague. Drawing on the Social Amplification of Risk F…
Visitor Proficiency Profiling and Risk Communication at a National Park
While cognitive heuristics may produce successful, efficient outcomes, they can also introduce predictable biases that may be unavoidable even for seasoned experts. This study connects the concept of “professional intuition” to the practice of strategic communication, suggesting that people may rely on heuristics to profile an audience. These judgments, in turn, influence crafting of communication to meet the audiences’ assumed needs, the definin…
Citizen views about public meetings
The current study seeks to demonstrate that a citizen views about public meeting structure and related groups matter in predicting satisfaction with public engagement and willingness to attend future meetings. Public health agencies frequently use public meetings to communicate risk information, but relatively little social science research has examined how potential meeting participants view them. Using survey data (N = 866) collected in seven U…

Applying the theory of planned behavior to study health decisions related to potential risks
This study examines theoretical linkages between the Risk Information Seeking and Processing model (RISP) and the Theory of Planned Behavior (TPB) in a context of health decision making related to potential risks involved in clinical trials. A decade after the RISP model was proposed, abundant empirical evidence attesting to the model’s robustness in depicting individuals’ motivations for risk information seeking and processing deems that it is c…
Are Issue-Cycles Culturally Constructed? A Comparison of French and American Coverage of Global Climate Change
We present a cross-cultural comparison of newspaper coverage of global warming in France and in the United States (1987-1997) as a case study to analyze the impact of culturally bound journalistic practices on media attention cycles. Based on the results of a content analysis, we show that France's coverage was more event-based, focused more on international relations, and presented a more restricted range of viewpoints on global warming than Ame…

Theory and practice of public meetings
Public meetings are among the most commonly used, frequently criticized, yet least understood methods of public participation in community planning. Although systematic research on public meetings is sparse, a vast, if fragmented, amount of experiential knowledge exists, and that can form the basis for a working theory of why some public meetings work and others do not. Characteristics of successful public meetings can be generally grouped by whe…
The Rituals of Public Meetings
Public meetings are often referred to as “rituals” to denote a largely symbolic activity with little concrete meaning. This essay explores how public meeting rituals may produce very real impacts on participants and pragmatic outcomes. Whereas tangible outputs of rituals are not always evident, ritual theory suggests that participants can derive latent meaning and significant comfort from their application. Although rituals serve to reify certain…
Why Citizens Do and Do Not Attend Public Meetings about Local Cancer Cluster Investigations
Why do citizens choose to attend or not to attend community public meetings about possible cancer clusters? To answer this question, we examine self‐report data collected during a series of mail surveys conducted in six communities experiencing current health investigations into suspect levels of cancer or cancer clusters. We analyze the data using quantitative content analysis while also providing qualitative summaries and categorizations of sur…
Framing Justice: Using the Concept of Procedural Justice to Advance Political Communication Research
Efforts aimed at increasing civic-mindedness must consider both what encourages and what discourages political engagement. Procedural justice argues that individuals care about the fairness of decision-making or deliberative procedures beyond whether the outcome of any future decision goes in their preferred direction. In turn, perceptions of procedural fairness influence participant satisfaction, commitment to the organization, perceived legitim…

Telling Stories About Global Climate Change: Measuring the Impact of Narratives on Issue Cycles
A theory of cyclical patterns in media coverage of environmental issues must account for more than intrinsic qualities of the issues themselves: Narrative factors must be considered. A content analysis of The New York Times and The Washington Post stories from 1980 to 1995 shows how media construct narratives about global warming and how these narratives may influence attention cycles. Empirically, the frequency of newspaper coverage shows cyclic…

The Function of Credibility in Information Processing for Risk Perception
This study examines how credibility affects the way people process information and how they subsequently perceive risk. Three conceptual areas are brought together in this analysis: the psychometric model of risk perception, Eagly and Chaiken's heuristic‐systematic information processing model, and Meyer's credibility index. Data come from a study of risk communication in the circumstance of state health department investigations of suspected can…
Media Coverage of Conflicts of Interest in Science
Some scientists are concerned that too much news media coverage of conflicts of interest in science threatens the public's belief in the integrity of the field, whereas other scientists worry that news media do not pay enough attention to conflicts of interest. To examine news media coverage of conflicts of interest in science, we conducted a ten-year content analysis of stories from the New York Times, Washington Post, Los Angeles Times, and USA…

Conflicted scientists: The “shared pool” dilemma of scientific advisory committees
Science advisors play a critical role in government policy making, yet these advisors are often equally attractive to regulated industry. Despite efforts to manage conflicts of interest among science advisors, allegations of conflict frequently plague advisory committee deliberations or outcomes. This article examines what we term the “shared pool” dilemma using data collected from 92 members of 11 US Food and Drug Administration advisory committ…

Defining Moments in Risk Communication Research: 1996–2005
Ten years ago, scholars suggested that risk communication was embarking on a new phase that would give increased attention to the social contexts that surround and encroach on public responses to risk information. A decade later, many researchers have answered the call, with several defining studies examining the social and psychological influences on risk communication. This article reviews risk communication research appearing in the published …

Public meetings about local cancer clusters: Exploring the relative influence of official versus symbolic risk messages on attendees’ post‐meeting concern
Scholars have long lobbied for a view of risk communication that supplants a conventional ‘transmission’ model of risk communication with an alternative that considers the complex social environment that accompanies any risk communication effort. Along these lines, this study examines the relative influence of official health messages versus symbolic risk messages on public meeting attendees’ post‐meeting concern about cancer clusters in six US c…
