Expert risk perceptions and the social amplification of risk: A case study in invasive tree pests and diseases

The Social Amplification of Risk Framework (SARF) is often used as a conceptual tool for studying diverse risk perceptions associated with environmental hazards. While widely applied, it has been criticised for implying that it is possible to define a benchmark ‘real’ risk that is determined by experts and around which public risk perceptions can subsequently become amplified. It has been argued that this objectification of risk is particularly problematic when there are high levels of scientific uncertainty and a lack of expert consensus about the nature of a risk and its impacts. In order to explore this further, this paper examines how ‘experts’ – defined in this case as scientists, policy makers, outbreak managers and key stakeholders – construct and assemble their understanding of the risks associated with two invasive tree pest and disease outbreaks in the UK, ash dieback and oak processionary moth. Through semi-structured interviews with experts in each of the case study outbreaks, the paper aims to better understand the nature of information sources drawn on to construct perceptions of tree health risks, especially when uncertainty is prevalent. A key conclusion is that risk assessment is a socially-mediated, relational and incremental process with experts drawing on a range of official, anecdotal and experiential sources of information, as well as reference to past events in order to assemble the risk case. Aligned with this, experts make attributions about public concern, especially when the evidence base is incomplete and there is a need to justify policy and management actions and safeguard reputation.

To fear or not to fear? Applying the social amplification of risk framework on two environmental health risks in Singapore

Smoke haze and dengue fever seasons were nationwide environmental health risk events that plagued Singapore between April and June 2013. Although relatively harmless compared to dengue fever, people in Singapore were visibly more disturbed by smoke haze. They engaged in preventive behaviors such as frantic purchasing of protective masks or staying indoors most of the time. Such reactions hint at the possibility of the social amplification of risk, a term coined to explain irrationally high public concerns over relatively minor risk issues, due to the visible nature of the risk event or people’s reactions to it. The current study aims to confirm the social amplification of risk for the haze event, as well as to test for the underlying reasons behind this phenomenon. Among the antecedents explored were the influence of information channels (traditional media and social media) on risk perception, negative affect, information seeking, and information sharing on the enactment of preventive behaviors. Data were collected from a sample of 343 college students through an online questionnaire. Results supported the presence of social amplification of risk for the haze event, and social media exposure was found to overshadow the influence of traditional media exposure on risk perception, negative affect, information seeking, information sharing, and preventive behaviors.

How are risks generated, developed and amplified? Case study of the crowd collapse at Shanghai Bund on 31 December 2014

The crowd collapse that took place in Chen Yi Plaza in the Shanghai Bund on 31 December 2014 claimed 36 lives and generated strong social ripple effects in China. Using the social amplification of risk framework (SARF), we analyze the roles played by various social groups and individuals during the exit transition following the disaster and investigate how risk information was attenuated, both intentionally and unintentionally, during the entry transition process. It was found that the overarching roles played by the government, specifically their spontaneous, uninformed and unilateral behaviors, are generally the main reason for the generation and evolution of risks, which can then easily be amplified by the media and public under the influence of cultural and commercial mindsets. Managing the sources that generate risks can be a crucial way to reduce the possibility of disasters in modern social risk management.

The Mediated Amplification of a Crisis: Communicating the A/H1N1 Pandemic in Press Releases and Press Coverage in Europe.

In the aftermath of the A/H1N1 pandemic, health authorities were criticized for failures in crisis communication efforts, and the media were accused of amplifying the pandemic. Considering these criticisms, A/H1N1 provides a suitable case for examining risk amplification processes that may occur in the transfer of information from press releases to print news media during a health crisis. We integrated the social amplification of risk framework with theories of news decisions (news values, framing) in an attempt to contribute to existing research both theoretically and empirically. We conducted a quantitative content analysis of press releases disseminated by health and governmental authorities, as well as the quality and tabloid press in 10 European countries between March 2009 and March 2011. Altogether 243 press releases, 1,243 quality press articles, and 834 tabloid press articles were coded. Consistent with research on news values and framing the results suggest that quality and tabloid papers alike amplified A/H1N1 risks by emphasizing conflict and damage, presenting information in a more dramatized way, and using risk-amplifying frames to a greater extent and risk-attenuating frames to a lesser extent than press releases. To some extent, the quality and tabloid press differed in how risk information was presented. While tabloid press articles seemed to follow the leading quality press with regards to content and framing of health crisis coverage, they exhibited a stronger emphasis on drama and emotion in the way they presented information.

How Agricultural Media Cover Safety Compared with Periodicals in Two Other Hazardous Industries.

This analysis featured a uniquely broad look at challenges and potentials for engaging agricultural and other industrial media more effectively in covering safety. It involved a content analysis of selected industry periodicals serving agriculture, mining, and transportation, which are three of the nation's most hazardous industries, in terms of human safety. Use of the social amplification of risk framework (SARF) provided insight on safety coverage. In particular, it tested previous research indicating that media coverage tends to amplify (increase) more than attenuate (decrease) a sense of risk. Analysis involved 18 periodicals (9 agriculture, 7 transportation, and 2 mining) spanning a five-year period from 2008 to 2012. Full-text digital analysis identified terms found in safety articles across all three industries. A manual review of articles revealed the quantity and nature of safety coverage within and among these industries. Results identified 528 safety-related articles published during the period. Transportation and mining periodicals averaged more than twice as many safety articles as the agricultural periodicals. The amount of coverage within the three industries also varied greatly. Findings on the nature of coverage supported previous media research within the SARF. Coverage across all three industries was clearly oriented more to amplifying than to attenuating risk. This study adds to the understanding of variations, commonalities, challenges, and potentials for enhancing safety coverage by media serving these three industries. It also provides direction for engaging industry media more effectively in the public safety mission. The authors recommend seven areas of opportunity for further research.

The social amplification of risk on Twitter: the case of ash dieback disease in the United Kingdom

It has long been recognised that the traditional media play a key role in representing risk and are a significant source of information which can shape how people perceive and respond to hazard events. Early work utilising the social amplification of risk framework (SARF) sought to understand the discrepancy between expert and lay perceptions of risk and patterns of risk intensification and attenuation with reference to the media. However, the advent of Web 2.0 challenges traditional models of communication. To date there has been limited consideration of social media within the SARF and its role in mediating processes of risk perception and communication. Against this backdrop, we focus on the social media platform Twitter to consider the social amplification of risk in relation to ash dieback disease (Hymenoscyphus fraxineus); a tree health issue that attracted intense media attention when it was first identified in the UK in 2012. We present an empirical analysis of 25,600 tweets in order to explore what people were saying about ash dieback on Twitter, who was talking about it and how they talked about it. Our discussion outlines the themes around which talk about ash dieback was orientated, the significance of users’ environmental ‘affiliations’ and the role of including links (URLs) to traditional media coverage. We utilise the notion of ‘piggybacking’ to demonstrate how information is customised in line with group/individual identities and interests and introduce the concept of the ‘frame fragment’ to illustrate how information is selected and moved around Twitter emphasising certain features of the messages. The paper affords a detailed consideration of the way in which people and organisations simultaneously appropriate, construct and pass on risk-relevant information. A conclusion is that social media has the potential to transform the media landscape within which the SARF was originally conceived, presenting renewed challenges for risk communication.

An Empirical Agent-Based Model to Simulate the Adoption of Water Reuse Using the Social Amplification of Risk Framework.

Water reuse can serve as a sustainable alternative water source for urban areas. However, the successful implementation of large-scale water reuse projects depends on community acceptance. Because of the negative perceptions that are traditionally associated with reclaimed water, water reuse is often not considered in the development of urban water management plans. This study develops a simulation model for understanding community opinion dynamics surrounding the issue of water reuse, and how individual perceptions evolve within that context, which can help in the planning and decision-making process. Based on the social amplification of risk framework, our agent-based model simulates consumer perceptions, discussion patterns, and their adoption or rejection of water reuse. The model is based on the "risk publics" model, an empirical approach that uses the concept of belief clusters to explain the adoption of new technology. Each household is represented as an agent, and parameters that define their behavior and attributes are defined from survey data. Community-level parameters-including social groups, relationships, and communication variables, also from survey data-are encoded to simulate the social processes that influence community opinion. The model demonstrates its capabilities to simulate opinion dynamics and consumer adoption of water reuse. In addition, based on empirical data, the model is applied to investigate water reuse behavior in different regions of the United States. Importantly, our results reveal that public opinion dynamics emerge differently based on membership in opinion clusters, frequency of discussion, and the structure of social networks.

Overcoming Theoretical Divisions in Risk Analysis: Expanding the Idea of Integration in the Social Amplification of Risk Framework

The field of risk analysis is divided along various lines. As early as 1988 the Social Amplification of Risk Framework (SARF) by Kasperson et al. was developed to overcome those divisions and to explain the phenomenon of diverging risk perceptions. This paper presents a meticulous examination of the SARF, one of the most cited theoretical frameworks in interdisciplinary risk analysis, as well as its critics. The SARF aspires to integrate theoretically across two different dimensions: various social-scientific approaches to risk and the tradition of technical risk assessment. With respect to the first dimension, we argue that the SARF is marred by profound vagueness as well as ambiguities that obfuscate the framework. With respect to the second dimension, we suggest that the SARF fails to achieve its objective for systematic reasons. To remedy these shortcomings, we put forward a more integrative concept of risk. This richer concept, then, helps us to shed light on diverging risk perceptions.

The Social Amplification of Haze-Related Risks on the Internet

abstractThis study explores the implications of the digital network society for public health communication and management through an empirical study on communication related to the transboundary haze crisis in Singapore. Using the Social Amplification of Risk Framework (SARF), the authors applied sentiment and thematic analysis on haze-related posts on an online discussion forum (HardwareZone) and a social networking site (Facebook), and to haze-related articles in The Straits Times (a newspaper). The study shows that the medium matters in social amplification of risk: Facebook had an effect on the amplification of emotions, while HardwareZone and The Straits Times did not. In addition, the results show that spikes in online risk amplification were strongly influenced by unprecedented events. They also suggest that anger expressed online may be linked to a sense of futility. Implications for practice and recommendations for future research are provided in the conclusion.

Ontario's Experience of Wind Energy Development as Seen through the Lens of Human Health and Environmental Justice.

The province of Ontario has shown great commitment towards the development of renewable energy and, specifically, wind power. Fuelled by the Green Energy Act (GEA) of 2009, the Province has emerged as Canada’s leader in wind energy development (WED). Nonetheless, Ontario’s WED trajectory is characterized by social conflicts, particularly around environmental health. Utilizing the Social Amplification of Risk Framework, this paper presents an eight-year longitudinal media content analysis conducted to understand the role Ontario’s media may be playing in both reflecting and shaping public perceptions of wind turbine health risks. We find that before and after the GEA, instances of health risk amplification were far greater than attenuations in both quantity and quality. Discourses that amplified turbine health risks often simultaneously highlighted injustices in the WED process, especially after the GEA. Based on these findings, we suggest that Ontario’s media may be amplifying perceptions of wind turbine health risks within the public domain. We conclude with policy recommendations around public engagement for more just WED.

The socio-environmental data explorer (SEDE): a social media–enhanced decision support system to explore risk perception to hazard events

ABSTRACTSocial media are increasingly recognized as a useful data source for understanding social response to hazard events in real time and in post-event analysis. This article establishes social media–enhanced decision support systems (SME-DSS) as a synergistic integration of social media and decision support systems (DSSs) to provide structured access to native, near real-time data from a large and diverse population to assess social response to social, environmental, and technological risk and hazard events. We introduce a prototype SME-DSS entitled socio-environmental data explorer (SEDE) to explore the opportunities and challenges of leveraging social media for decision support. We use a winter storm during 25–28 January 2015 that accumulated record amounts of snow along the East Coast of the United States as a case study to evaluate SEDE in helping assess social response to environmental risk and hazard events as well as evaluate social media as a theoretical component within the social amplification of risk framework (SARF) that serves as a theoretical foundation for SME-DSS.

Agent-based computational modelling of social risk responses

A characteristic aspect of risks in a complex, modern society is the nature and degree of the public response – sometimes significantly at variance with objective assessments of risk. A large part of the risk management task involves anticipating, explaining and reacting to this response. One of the main approaches we have for analysing the emergent public response, the social amplification of risk framework, has been the subject of little modelling. The purpose of this paper is to explore how social risk amplification can be represented and simulated. The importance of heterogeneity among risk perceivers, and the role of their social networks in shaping risk perceptions, makes it natural to take an agent-based approach. We look in particular at how to model some central aspects of many risk events: the way actors come to observe other actors more than external events in forming their risk perceptions; the way in which behaviour both follows risk perception and shapes it; and the way risk communications are fashioned in the light of responses to previous communications. We show how such aspects can be represented by availability cascades, but also how this creates further problems of how to represent the contrasting effects of informational and reputational elements, and the differentiation of private and public risk beliefs. Simulation of the resulting model shows how certain qualitative aspects of risk response time series found empirically – such as endogenously-produced peaks in risk concern – can be explained by this model.

A Study on the Application and Proposals of Safety Culture, New Public Management and Social Amplification of Risk Framework via Ship Accidents in Korea

This paper provides a study on the application and proposals of safety culture, new public management and social amplification of risk framework via ship accidents in Korea. This document analyzes what are the concept of safety culture, new public management as well as social amplification and risk framework and describes how 3 issues act, harmonize, interrelate through M/V Sewol accident. Korean government is needed to apply social amplification of risk framework to the in order to promote the safety culture in the maritime administration. Hence, this paper proposes safety framework in order to prevent and resolve future unexpected accident especially for maritime field.

Forecast communication through the newspaper Part 1: Framing the forecaster

This review is split into two parts both of which address issues of forecast communication of an environmental disaster through the newspaper during a period of crisis. The first part explores the process by which information passes from the scientist or forecaster, through the media filter, to the public. As part of this filter preference, omission, selection of data, source, quote and story, as well as placement of the same information within an individual piece or within the newspaper itself, can serve to distort the message. The result is the introduction of bias and slant—that is, the message becomes distorted so as to favor one side of the argument against another as it passes through the filter. Bias can be used to support spin or agenda setting, so that a particular emphasis becomes placed on the story which exerts an influence on the reader’s judgment. The net result of the filter components is either a negative (contrary) or positive (supportive) frame. Tabloidization of the news has also resulted in the use of strong, evocative, exaggerated words, headlines and images to support a frame. I illustrate these various elements of the media filter using coverage of the air space closure due to the April 2010 eruption of Eyjafjallajökull (Iceland). Using the British press coverage of this event it is not difficult to find examples of all media filter elements, application of which resulted in bias against the forecast and forecaster. These actors then became named and blamed. Within this logic, it becomes only too easy for forecasters and scientists to be framed in a negative way through blame culture. The result is that forecast is framed in such a way so as to cause the forecaster to be blamed for all losses associated with the loss-causing event. Within the social amplification of risk framework (SARF), this can amplify a negative impression of the risk, the event and the response. However, actions can be taken to avoid such an outcome. These actions revolve around use of words and quotes that cannot easily be exaggerated or turned into “sledgehammer” or blaming headlines, while tracking the media for developing frames so as to guide future communications.

Enhancing the Social Amplification of Risk Framework (SARF) by exploring trust, the availability heuristic, and agricultural advisors' belief in climate change

Using a survey of agricultural advisors across the Midwestern U.S., this paper explores two additions to the Social Amplification of Risk Framework (SARF)—trust in information sources and the availability heuristic. Connections between demographic factors, belief in climate change, perceived risk, and advisors' attitudes toward adaptation to climate change are examined. Three-fourths of advisors believe climate change is occurring, but disagree on the human contribution. Trust in information sources predicted agricultural advisors' belief in climate change. Consistent with the availability heuristic, perceiving variability in weather made advisors more likely to believe in anthropogenic climate change. Believing climate change is at least partly human caused increased agreement that agricultural adaptation is important. Perceiving greater risk from potential climate impacts and noticing variable weather also significantly increased adaptation attitudes. Findings suggest that trust and availability heuristic could be added to help explain the processes of social amplification and attenuation of risk.

Social Media and the Virality of Risk: The Risk Amplification through Media Spread (RAMS) Model

AbstractSocial media have transformed traditional configurations of how risk signals related to an infectious disease outbreak (IDO) are transmitted from public health authorities to the general public. However, our understanding of how social media might influence risk perceptions during these situations, and the influence of such processes on ensuing societal responses remains limited. This paper draws on key ideas from the Social Amplification of Risk Framework (SARF), Socially Mediated Crisis Communication (SMCC) model and a case study of the US Centers for Disease Control and Prevention’s (CDC) social media management of the 2009 H1N1 pandemic to propose a new conceptual model. The Risk Amplification through Media Spread (RAMS) model brings clarity to the new complexities in media management of IDOs by delineating the processes of message diffusion and risk amplification through communication channels that are often highly integrated due to social media. The model offers recommendations for communication priorities during different stages of an IDO. The paper concludes with a discussion of the RAMS model from theoretical and applied perspectives, and sets the direction for future conceptual refinement and empirical testing.

Social agents and news media as risk amplifiers: a case study on the public debate about the E. coli outbreak in Germany 2011

The social amplification of risk framework highlights the role which the news media play in risk communication by interacting with other agents in amplifying risk. However, the precise ways in which the media and other social agents actually amplify risks in public debates are unclear. In this article we draw on insights from the sociology of news to examine whether and to what extent social agents and news media amplify an emerging health risk. We use the debate about the Escherichia coli outbreak in Germany in 2011 to examine three issues: the amount of risk reporting by news media and social agents in their function as news sources; their evaluation of risk; and how they contribute to the escalation of risk, also known as ripple effects. In this article we draw on data from a content analysis of press releases from public health authorities and affected stakeholders and of news items in leading German news media. We found that the affected stakeholders were amplifying the risk to the greatest extent. We also found that there was a shift over time in the use of dominant frames. At the start of the debate the risk was framed as a public health issue and linked to medical-scientific progress. As the debate developed, more attention was given to political and economic consequences of the outbreak and the original health risk event was layered by other risk-related events.

Understanding tourism leaders’ perceptions of risks from climate change: an assessment of policy-making processes in the Maldives using the social amplification of risk framework (SARF)

Coastal tourism destinations are highly vulnerable to climate change risks, including sea-level rise, inundation, and extreme weather events. While such risks pose major challenges to the sustainability of these destinations, they have been insufficiently examined in tourism research. This study uses the social amplification of risk framework as a basis for understanding how climate change risks are perceived and what processes lead to an amplification or attenuation of risk perceptions at management and governance levels. In the context of the extremely low-lying Maldives, 12 leading tourism stakeholders, including representatives of government, industry, and NGOs, were interviewed to gather empirical data on risk perceptions. Results indicate that, while climate change risks are amplified for international audiences, several factors lead to an attenuation of risks for domestic audiences. As a result, local tourism stakeholders are not immediately concerned, and adaptation measures are woefully inadequate to cope with future climate risks. Detailed reference is made to the policy inertia found, the conflicts inherent in playing down risk in order to attract jobs, profitable tourism investment and tourists, and the equally pressing need to stress risks in order to attract expertise and funds to enable adaptation policies to be designed and funded.

Modeling of Public Risk Perception and Risk Communication Research: In A Social-Cognitive Direction

This study begins with a review of commonly discussed dimensions of public risk perception that may influence public opinion toward risks. Factors that have been revealed by the literature to have substantial impact on risk perception, such as demographic background, trust, and media environment, are also discussed. Meanwhile, we evaluate two well-known research models in the realm of risk analysis: 1) the psychometric paradigm, and 2) the social amplification of risk framework (SARF). Based on a literature review, this study suggests that, besides the psychological and social approach, models of risk perception and risk communication research should shift to a more comprehensive one by considering the interrelations between laypeople and the environment. This study proposes a research model from the perspective of social cognitive theory (SCT) as a potential framework for future studies: 1) in the societal environment, individuals' risk perception and information seeking behavior, which is determined by risk perception will be influenced by trust in regulators and interpersonal trust; 2) in the media environment, individuals' risk perception and information seeking behavior will be influenced by individuals' perceived information characteristics. Knowledge about risk accumulated through information seeking will change risk perception in a longitudinal process.
