RESUMEN
Previous research suggests that when individuals have limited knowledge to make sense of new or emerging technologies, they may rely more on available cues, such as the fairness of those managing the risks, when developing their attitudinal and behavioral responses to the technology. To examine this further, we designed an online experiment (N = 1,042) to test the effects of risk managers' nonoutcome fairness on individuals' selective exposure to additional information and perceived risk. As the study context, we used the development of enhanced geothermal systems (EGS), which uses drilling to tap deep underground sources of heat for district heating and electricity and remains low in familiarity among the U.S. public. The results suggest that participants who read about the fair risk manager were subsequently more likely to have positive attitudes toward EGS development. In turn, those with more positive attitudes were more likely to select and read positively valenced articles about EGS, resulting in an indirect effect of the fairness condition. Although this study also explored whether uncertainty moderated this fairness effect on information seeking, it found no evidence. Additionally, when participants were exposed to information featuring fair risk managers, perceived risk decreased, an effect that was mediated by beliefs that EGS was controllable and not dreadful. These results underscore the importance of using practices that will increase nonoutcome fairness in the introduction of new technologies.

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 interdisciplinary field. We then review a selection of prominent cognitive, cultural, and social risk communication scholarship appearing in the published literature since 2010. Studies on trust in risk communication messengers continued to figure prominently, while new research directions emerged on the opportunities and critical challenges of enhancing transparency and using social media. Research on message attributes explored how conceptual insights particularly relating to framing, affective and emotional responses, and uncertainty might be operationalized to improve message effectiveness. Studies consistently demonstrated the importance of evaluation and how varying single attributes alone is unlikely to achieve desired results. Research on risk communication audiences advanced on risk perception and multiway engagement with notable interest in personal factors such as gender, race, age, and political orientation. We conclude by arguing that the field's interdisciplinary tradition should be further nurtured to drive the next evolutionary phase of risk communication research.
RESUMEN
The interplay between science, risk assessment and risk management has always been complex, and even more so in a world increasingly characterised by rapid technical innovation, new modes of communication, suspicion about authorities and experts, and demands for people to have a say in decisions that are made on their behalf. In this challenging era where scientific advice on food safety has never been in greater demand, risk managers should effectively navigate the interplay between facts and values and be able to rely on robust and fit-for-purpose risk assessments to aid them. The fact that societal resistance is often encountered when scientific advice on food safety operates at a distance from social values and fails to actively engage with citizens, has led to increasing emphasis on the need to advance forms of risk assessment that are more contextual, and socially sound and accountable. EFSA's third Scientific Conference explored how risk assessments could be constructed to most usefully meet society's needs and thus connect science with society, while remaining scientifically robust. Contributors to the conference highlighted the need to: (1) frame risk assessments by clear policy goals and decision-making criteria; (2) begin risk assessments with an explicit problem formulation to identify relevant information; (3) make use of reliable risk assessment studies; (4) be explicit about value judgements; (5) address and communicate scientific uncertainty; (6) follow trustworthy processes; (7) publish the evidence and data, and report the way in which they are used in a transparent manner; (8) ensure effective communication throughout the risk analysis process; (9) involve society, as appropriate; and (10) weigh risks and benefits on request. Implementation of these recommendations would contribute to increased credibility and trustworthiness of food safety risk assessments.
RESUMEN
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 concern, messages that highlighted both human responsibility for and the imminent nature of the risk failed to enhance conservation intentions compared with messages highlighting animal responsibility. However, when messages highlighting human responsibility placed the risk in a temporally distal frame, conservation intentions increased among people low in biospheric concern. We assess the underlying mechanism of this effect and discuss the value of temporal framing in overcoming motivated skepticism to improve science communication.
RESUMEN
This study investigates the level of awareness about funding influences and potential conflicts of interests (COI) among early career researchers. The sample for this study included users of one or more of the 14 U.S. laboratories associated with the National Nanotechnology Infrastructure Network. To be eligible, respondents must have been either still completing graduate work or <5 years since graduation. In total, 713 early career researchers completed the web survey, with about half still in graduate school. Results indicate that although respondents were aware of potential funding and COI influences on their work, they remained largely ignorant of their role in addressing or managing these issues. Respondents often attributed the responsibility of addressing these issues to their supervisors. Respondents who had received some training around these issues, however, were more likely to assume more personal responsibility. Overall, this study points out that ignorance among early career researchers is less about awareness of funding and COI issues and more about taking personal responsibility for addressing these issues.

Genetic modification (GM) of crops and climate change are arguably two of today's most challenging science communication issues. Increasingly, these two issues are connected in messages proposing GM as a viable option for ensuring global food security threatened by climate change. This study examines the effects of messages promoting the benefits of GM in the context of climate change. Further, it examines whether explicit reference to "climate change," or "global warming" in a GM message results in different effects than each other, or an implicit climate reference. An online sample of U.S. participants (N = 1050) were randomly assigned to one of four conditions: "climate change" cue, "global warming" cue, implicit cue, or control (no message). Generally speaking, framing GM crops as a way to help ensure global food security proved to be an effective messaging strategy in increasing positive attitudes toward GM. In addition, the implicit cue condition led to liberals having more positive attitudes and behavioral intentions toward GM than the "climate change" cue condition, an effect mediated by message evaluations.

Since 1960, bat rabies variants have become the greatest source of human rabies deaths in the United States. Improving rabies awareness and preventing human exposure to rabid bats remains a national public health priority today. Concurrently, conservation of bats and the ecosystem benefits they provide is of increasing importance due to declining populations of many bat species. This study used a visitor-intercept experiment (N = 521) in two U.S. national parks where human and bat interactions occur on an occasional basis to examine the relative persuasiveness of four messages differing in the provision of benefit and uncertainty information on intentions to adopt a rabies exposure prevention behavior. We found that acknowledging benefits of bats in a risk message led to greater intentions to adopt the recommended rabies exposure prevention behavior without unnecessarily stigmatizing bats. These results signify the importance of communicating benefits of bats in bat rabies prevention messages to benefit both human and wildlife health.

As anthropogenic stressors threaten the health of marine ecosystems, there is a need to better understand how the public processes and responds to information about ocean health. Recent studies of public perceptions about ocean issues report high concern but limited knowledge, prompting calls for information campaigns to mobilize public support for ocean restoration policy. Drawing on the literature from communication, psychology and related social science disciplines, we consider a set of social-cognitive challenges that researchers and advocates are likely to encounter when communicating with the public about ocean health and emerging marine diseases--namely, the psychological distance at which ocean issues are construed, the unfamiliarity of aquatic systems to many members of the public and the potential for marine health issues to be interpreted through politicized schemas that encourage motivated reasoning over the dispassionate consideration of scientific evidence. We offer theory-based strategies to help public outreach efforts address these challenges and present data from a recent experiment exploring the role of message framing (emphasizing the public health or environmental consequences of marine disease) in shaping public support for environmental policy.

This study examines support for the genetic modification (GM) of crops in the context of preventing "late blight," a devastating potato and tomato disease that caused the Irish Potato Famine in the 1850s and results in substantial crop loss today. We surveyed U.S. adults who do the primary grocery shopping in their household (n = 859). Half of the respondents were randomly assigned to read a vignette describing late blight before responding to questions about GM, whereas the other half read a vignette about generic crop disease before responding to questions. We also examine how the perceived fairness of decision makers relates to GM support and the perceived legitimacy of GM decision making. We found that disease specificity mattered less to support and legitimacy than the perceived fairness of decision makers. The perceived risks of GM to human and environmental health negatively related to GM support and legitimacy, whereas the perceived benefits (e.g. reduced threats to crops and a more secure food supply) positively related to support and legitimacy. Objective knowledge about GM had a small, negative relationship with legitimacy whereas self-assessed familiarity with GM had a positive relationship. Overall, the results offer additional confirmation of past findings from more localized settings that perceived fairness of decision makers matters to support for GM and underscore the importance of considering how risk managers' behaviors and actions are perceived alongside individuals' perceptions about the risks and benefits.

This study extends a risk information seeking and processing model to explore the relative effect of cognitive processing strategies, positive and negative emotions, and normative beliefs on individuals' decision making about potential health risks. Most previous research based on this theoretical framework has examined environmental risks. Applying this risk communication model to study health decision making presents an opportunity to explore theoretical boundaries of the model, while also bringing this research to bear on a pressing medical issue: low enrollment in clinical trials. Comparative analysis of data gathered from 2 telephone surveys of a representative national sample (n = 500) and a random sample of cancer patients (n = 411) indicated that emotions played a more substantive role in cancer patients' decisions to enroll in a potential trial, whereas cognitive processing strategies and normative beliefs had greater influences on the decisions of respondents from the national sample.

Dependence in nanotechnology on external funding and academic-industry relationships has led to questions concerning its influence on research directions, as well as the potential for conflicts of interest to arise and impact scientific integrity and public trust. This study uses a survey of 193 nanotechnology industry and academic researchers to explore whether they share similar concerns. Although these concerns are not unique to nanotechnology, its emerging nature and the prominence of industry funding lend credence to understanding its researchers' views, as these researchers are shaping the norms and direction of the field. The results of the survey show general agreement that funding sources are influencing research directions in nanotechnology; many respondents saw this influence in their own work as well as other researchers' work. Respondents also agreed that funding considerations were likely to influence whether researchers shared their results. Irrespective of their institutional affiliation or funding status, twice as many researchers as not considered financial conflicts of interest a cause for concern, and three times as many respondents as not disagreed financial conflicts of interest in nanotechnology were uncommon. Only a third was satisfied with the way that conflicts of interest are currently managed and believed current procedures would protect the integrity of nanotechnology research. The results also found differences in views depending on researchers' institutional affiliation and funding status.

In response to low influenza vaccination rates among health care workers, health officials have explored determinants of uptake and developed communication interventions. Key to these efforts is how workers seek and attend to vaccine information. We applied a model of risk information seeking and processing to survey 226 physicians and nurses at a large, urban hospital (response rate = 5.7%; cooperation rate = 91.5%). Our goals were to (1) apply the model to a new setting, audience, and issue and (2) explore novel concepts (e.g., source credibility and information usefulness) and moderating relationships among variables. Consistent with previous research, information subjective norms-perceived social pressure to remain informed about vaccination-were a strong predictor of information seeking and systematic processing. Neither source credibility nor information usefulness independently increased explained variance, although they moderated the relationship between norms and communication behavior. We discuss theoretical and practical implications of these findings.

Research suggests that fairness perceptions matter to people who are asked to evaluate the acceptability of risks or risk management. Two separate national random surveys (n = 305 and n = 529) addressed Americans' concerns about and acceptance of nanotechnology risk management in the context of the degree to which they view scientists and risk managers as fair. The first survey investigated general views about scientists across four proposed dimensions of fairness (distributional, procedural, interpersonal, and informational). The results show that respondents who believe that the outcomes of scientific research tend to result in unequal benefits (distributional fairness) and that the procedures meant to protect the public from scientific research are biased (procedural fairness) were more concerned about nanotechnology. Believing scientists would treat them with respect (interpersonal fairness) and ensure access to information (informational fairness) were not significant predictors of concern. The second study also looked at these four dimensions of fairness but focused on perceptions of risk managers working for government, universities, and major companies. In addition to concern, it also examined acceptance of nanotechnology risk management. Study 2 results were similar to those of study 1 for concern; however, only perceived informational fairness consistently predicted acceptance of nanotechnology risk management. Overall, the study points to the value of considering fairness perceptions in the study of public perceptions of nanotechnology.

Low patient accrual in clinical trials poses serious concerns for the advancement of medical science in the United States. Past research has identified health communication as a crucial step in overcoming barriers to enrollment. However, few communication scholars have studied this problem from a sociopsychological perspective to understand what motivates people to look for or pay attention to information about clinical trial enrollment. This study applies the model of Risk Information Seeking and Processing (RISP) to this context of health decision making. By recognizing the uncertainties embedded in clinical trials, we view clinical trial enrollment as a case study of risk. With data from a random-digit-dial telephone survey of 500 adults living in the United States, we used structural equation modeling to test the central part of the RISP model. In particular, we examined the role of optimistic feelings, as a type of positive affect, in motivating information seeking and processing. Our results indicated that rather than exerting an indirect influence on information seeking through motivating a psychological need for more information, optimistic feelings have more direct relationships with information seeking and processing. Similarly, informational subjective norms also exhibit a more direct relationship with information seeking and processing. These results suggest merit in applying the RISP model to study health decision making related to clinical trial enrollment. Our findings also render practical implications on how to improve communication about clinical trial enrollment.

This study investigates whether perceived fairness of doctor-patient interactions relates to individuals' willingness to communicate with their doctors about clinical trial enrollment. It also explores how willingness to talk, the perceived fairness of interactions, and trust in doctors relate to intentions to participate in a future clinical trial. Results from a random digit dial (RDD) telephone survey of U.S. adults (N = 500) measured respondents' willingness to talk to their doctors about clinical trials and intentions to participate in future trials. Perceived fairness of interactions and trust in doctors were associated with willingness to talk about clinical trials. A negative relationship emerged between perceived fairness of interactions and intentions to participate when willingness to talk was introduced into the equation. This relationship suggested that when respondents were more willing to talk to their doctors and perceived these discussions as fair, they were also less likely to express intentions to enroll in future trials. In turn, perceiving these interactions as less fair was related to greater intention to enroll. Fairness of interactions and trust in doctors were less relevant to respondents who were less willing to talk to their doctors; however, these respondents also were more likely to express intentions to enroll in future clinical trials.

OBJECTIVE: To investigate cancer patients' motivations for clinical trial enrollment, this study tests the proposition that a model of Risk Information Seeking and Processing (RISP) could serve as an antecedent to the Theory of Planned Behavior (TPB). METHODS: With data from a telephone survey, we examined whether components of the RISP model had significant impact on belief-based attitudes and behavioral intentions. RESULTS: Risk judgment and affective responses, especially optimistic feelings, consistently related to attitudes and behavioral intentions. Trust in doctors also significantly related to our respondents' positive attitudes toward clinical trials. CONCLUSION: The RISP model might have more constrained applicability as compared to the TPB in explaining cancer patients' motivations for clinical trial enrollment. However, certain components of the RISP model seemed to contribute to our respondents' attitude formation as interesting additions to the TPB. PRACTICE IMPLICATIONS: Communication about clinical trials is a balance act between providing sufficient information about the potential risks and benefits involved in a clinical trial and managing emotional responses that cancer patients associate with participation. Both acts contribute to the formation of positive attitudes toward clinical trials among cancer patients, which is the driving force behind their intentions for clinical trial enrollment.

A knowledge, attitudes, and practices (KAP) questionnaire combined with entomological surveys of residential mosquito-breeding sites were conducted in two Upstate New York neighborhoods. We tested the hypothesis that "correct" West Nile virus (WNV) knowledge and perceptions correspond with the use of practices that prevent mosquitoes from breeding and biting. Our results demonstrate that perceptions of WNV relate to the number of positive containers in yards and the use of mosquito preventive measures. In contrast, WNV knowledge was not related. Culex pipiens and Cx. restuans were common species found breeding in containers. Aedes japonicus was the most abundant species in 77% of positive containers (buckets, flower pots, and birdbaths). This new, invasive mosquito together with the Culex species identified in this study represent significant potential as vectors of WNV and other arboviruses affecting human and animal health. We conclude that more training and education programs should focus on WNV control strategies and recognizing mosquito breeding in residential yards. This is the first study to directly investigate the relationship between KAP and breeding of WNV vectors in residential yards.
