Perception of technological risk: insights from research and lessons for risk communication and management

Technology has become a familiar companion in all areas of life. Production consumption, administration, education, communication, and leisure activities are all shaped by the use of technologies. However, people often associate with the term ‘technology’ attributes, such as catastrophic and potentially dangerous, and tend to take the benefits of technological products for granted. This asymmetry in risk–benefit perception is one of the main reasons why many consumers are concerned about ‘hidden’ risks of technologies and why they demand stringent regulatory actions when they feel unduly exposed to potential emissions or waste products associated with the lifecycle of technologies. This situation is often aggravated by social amplification processes, by which even small risks receive high media attention and are blown out of proportion in the public arena. At the same time, however, one needs to acknowledge that many technologies have the potential to harm the human health and the environment. The purpose of this article is to review our knowledge about risk perception with respect to technologies, in particular emerging technologies, and to suggest possible strategies to use this knowledge for improving our risk management practice. Technological risk perception is defined in this article as the processing of physical signals and/or information about a potentially harmful impact of using technology and the formation of a judgment about seriousness, likelihood, and acceptability of the respective technology. Based on the review of psychological, social, and cultural factors that shape individual and social risk perceptions, we have attempted to develop a structured framework that provides an integrative and systematic perspective on technological risk perception and that may assist risk management and regulation in taking perceptions into account.     

Trust,acceptance and knowledge of technological and environmental hazards in Chile

Studies over the past decade have found empirical links between trust in risk management institutions and the risk perceptions and acceptability of various individual hazards. Mostly addressing food technologies, no study to date has explored wider possible relationships among all four core variables (risk, benefit, trust and acceptability) covering a heterogeneous group of hazards. Our prime objective was to ascertain effects among social trust in regulatory entities, and the public's perceived risk, perceived benefit and the degree of acceptability towards both technological and environmental hazards. We also assess whether trust in regulatory authorities is the cause (causal model) or a consequence (associationist model) of a hazard's acceptability for a wide and heterogeneous range of hazards on all four core variables. Using a web‐based survey, 539 undergraduates in Chile rated the five variables across 30 hazards. Implications for technology and environmental risk management organizations are discussed. Independent of the magnitude of the perceived risk or benefit surrounding a given hazard, or how knowledgeable the public claim to be of it, the trust sustained in regulatory institutions will either generate or be the consequence of public attitudes towards the hazard.     

Conceptualising social risk and business risk associated with private sector development projects

There are various definitions of social risk. For some, social risk pertains to social protection, and risk-taking is thought to enhance human welfare. For others, social risk is contrasted with empirical risk, where the perception of risk by lay members of society differs from that of experts in any given field. More recently, social risk has come to be associated with the potential future negative social impacts of corporate activities and private sector development on individuals and groups. This paper theorises the relationships between social risk and business risk in the context of private sector developments. Many business leaders continue to conflate social risk with their existing understandings of business risk, with social risk understood to be the risk to the business arising from the actions of community stakeholders. Conceiving of social risk in this way has implications for the discrete identification, prevention and mitigation of social and business risks and impacts, and has ramifications for corporate risk management strategies, as well as companies’ relationships with community stakeholders.     

Improving lay understanding of exposure to electromagnetic fields; the effect of information on perception of and responses to risk

Studies show that, although many people are concerned about the potential health risks of being exposed to electromagnetic fields (EMF), lay understanding of exposure, an important determinant of risk perceptions and responses, is limited. In an online consumer panel (n = 245), we tested the effects of providing people with information about EMF on lay understanding of exposure, and on perceptions and responses to risks, using an experimental 2?×?2?×?2 design. Providing people with specific information explaining the distance–exposure relationship, clarifying EMF policy, or specifying personal exposure management options actions resulted in a better understanding of exposure. We demonstrated that information provision as such had no effects on concerns about EMF nor on perceived risk of personal sources, i.e. mobile phones, but lowered perception of risk of public sources, i.e. mobile phone base stations and high-voltage power lines. In addition, information explaining the distance–exposure relationship in combination with policy information resulted in reduced self-reported risk-aversive responses. Moreover, participants who understood more about exposure in relation to the distance to the source showed lower perceptions of risk, were less likely to restrict their own exposure, and more likely to accept new installations of public sources of EMF in their neighborhood. In contrast, awareness that exposure was mainly determined by personal use of EMF sources corresponded with higher perceptions of risk from personal sources and a higher likelihood to restrict one’s own exposure. Our findings provide focal points for improving communication on EMF. In particular, we suggest to include information clarifying the distance–exposure relationship to improve understanding of exposure.     

Precautionary advice about mobile phones: public understandings and intended responses

There is a widespread academic and policy debate about public responses to precaution in public health campaigns. This paper explores these issues in relation to the precautionary stance adopted in the UK around the regulation of mobile telecommunications. The aim of the paper is to examine the nature of attitudes to precaution, and the way in which these, along with other relevant variables, relate to the intention to adopt relevant behaviours. The results from an experimental study (n = 173) indicate that people distinguish between two dimensions of precaution: firstly in relation to its value or necessity per se and secondly as anchored to notions of governance. The two variables differentially relate to other variables including trust and uncertainty, and are predictive of intended behaviour change indirectly, through worry about mobile phone risks. Precautionary advice was generally interpreted as causing concern rather than providing reassurance. The results suggest that precaution may be considered a valuable stance but this does not mean that it is seen as good governance or that it will reduce concern. Whilst the discourse of precaution is aimed at reducing concern, it appears that the uptake of relevant behaviours is largely triggered by worry.     

Engineered nanomaterials: risk perception,regulation and insurance

Concerns surrounding the health risk of engineered nanomaterials, effective regulation and the lack of specifically tailored insurance products for the nanotechnology sector are putting the industry’s long-term economic viability at risk. From the perspective of the underwriter, this article speculates on the relationship between risk perception, regulation and insurability. In the nanotechnology sector, regulators are currently failing to keep pace with innovation, and insurers generally lack guiding principles for underwriting occupational risk from nanomaterial exposure. Such vulnerabilities when combined with misguided risk perceptions can lead to the overpricing of risk transfer and ill-conceived regulatory initiatives, thus potentially exhausting resources and stifling innovation in the sector. In the absence of well-developed regulatory protocols, the insurance industry has, and will continue, to occupy a key role as an effective lobby in terms of improved risk management practice. We suggest that the insurance industry will increasingly rely on control banding frameworks and ‘risk mitigation at source’ methods developed in conjunction with their clients to manage severe acute diversifiable risks. Long tail risk will continue to represent a serious challenge to insurers and regulators. In the meantime, insurers will have to bridge their current needs with improvised solutions. As an example of one possible solution, we outline a framework that utilizes financial instruments to hedge an insurer’s exposure to uncertain estimates of these long-term risks.     

The two faces of social capital in private flood mitigation: opposing effects on risk perception,self-efficacy and coping capacity

Impacts of flooding are expected to increase, most notably in residential areas. As a consequence, private households are increasingly encouraged to engage in private flood mitigation complementary to public measures. Despite the growing literature on private flood mitigation, little is known about how social capital influences households’ perception of and coping with flood risks. This study draws on survey data of 226 flood-prone households in two Austrian Alpine municipalities, both recently affected by riverine flooding. We show that social capital cuts both ways: on the positive side, social capital increases perceived self-efficacy and provides critical support during and most notably after flood events. On the negative side, social capital reduces flood risk perceptions of private households. While social ties are effective when responding to and recovering from floods, the expectation of social support downplays risk, making precautionary action by households less likely. The results also show that flood-affected households receive more social support than they provide to others. In the long-run, this can lead to a problematic reciprocity imbalance, challenging the long-term stability of the interpersonal exchanges underlying social capital. Among the various sources of social support, informal social networks (neighbours, friends and relatives) provide the most important workforce in the response and recovery phase of a flood event. It is therefore crucial for flood risk management to recognise and promote the protective quality of social capital alongside conventional structural and non-structural measures.     

Public sector risk managers and spending cuts: mitigating risks

This paper reports case study research, the results of which are used to consider whether councils have recognised the potentially substantially increased social risks they may create as they seek to reduce their spending in line with the UK Government’s programme of public sector austerity. It discusses the conceptual shift in the public sector risk management literature towards social risk management (SRM), presents empirical evidence of social risks and considers the approach to SRM developed by other organisations. It finds no evidence of SRM within the case study authorities and so advocates a shift in the public sector risk management culture from a preoccupation with defensive-institutional risk management practices to a more proactive social dimension. In so doing, it discusses the goals of SRM, the constraints limiting their achievement, metrics for measuring social risk, tools for mitigating social risk and the problems faced when operationalising SRM.     

The constitutive element of probabilistic agency in risk: a semantic analysis of risk,danger, chance,and hazard

Defining central concepts with accuracy is crucial to any scientific discipline. A recent debate over risk definitions in this journal illustrates the far reaching consequences of divergent definitions. Aven and Renn define risk as a social construct while Rosa defines risk as an ontological fact. Both claim that their definition reflects the common usage of the word risk. Through a semantic analysis this paper points to a constitutive element of what is termed probabilistic agency in the risk concept. In this respect, risk is distinct from danger, and because Rosa’s main argument is based on the apparent synonymy between risk and danger, the premises for his risk ontology are not valid. The paper furthermore argues that Aven and Renn’s attempt to bridge between epistemology and ontology is based on a distinction between a conceptual level of risk and its practical application which is impossible to uphold if a risk definition is to be in accordance with the ordinary usage of the word. The paper concludes by arguing that risks are only real within a subjective ontology.     

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.     

Redefining the issues of risk and public acceptance: The social viability of technology

A conceptual framework is proposed within which the notion of risk as normally used in risk assessment (RA) could be enlarged in line with the real substance of social issues of technology policy, to help avoid RA's threatened irrelevance to social decisionmaking. It is argued that the frequent organizational incoherence and thus the unviability of modern technology arises from ‘social alienation’ between the innovation-commitment phase and the implementation of the technology in society. The roles of technical elites and of particular concepts of technology in this alienation are emphasized.     

Vulnerability,values and heterogeneity: one step further to understand risk perception and behaviour

The aim is to investigate differences in risk perception and behaviour among different population groups selected by gender, age, country of birth, disability and sexual orientation in the light of general values and vulnerability. The analyses use data from two Swedish national surveys from 2005 to 2008. People with foreign background perceive controlled and dread risks as a greater threat than do native-born people, but there is no difference in behaviour when general values and vulnerability have been controlled for. Compared to women, men rate known and dread risks as lower, but controlled risks as higher. Further, men’s behaviour is more risk-oriented and less risk-reducing, and homosexuals and bisexuals are more likely than heterosexuals to report risk behaviour. Compared to previous studies of the so-called White Male Effect carried out in the USA, gender does not play a similar role in Sweden. On the contrary, it seems as if gender is of less importance and that the strength of the association varies depending on type of risk or risk behaviour.     

Corporate social responsibility and corruption risk: A global perspective

This paper extends our knowledge on corporate corruption risk by examining whether and to what extent corporate social responsibility (CSR) affects firm-level corruption risk. Using a cross-country sample of major multinational firms, we find that firm-level CSR mitigates corruption risk. On closer examination, we find that the relationship between CSR and corruption risk is mediated by country-level variables such as institutional quality, protection of minority shareholders’ rights, stock market development and freedom of the press. Further, we find that in emerging countries, CSR mitigates corruption risk only when the country-level institutional quality is high and citizens enjoy press freedom. Our findings suggest that both formal institutions and the quality of civil society influence the effect of CSR on corruption risk. Our results remain robust to controls for endogeneity and potential sample selection bias.     

Collective efficacy and natural hazards: differing roles of social cohesion and task-specific efficacy in shaping risk and coping beliefs

Abstract

Previous research in non-disaster contexts has shown that the concept of collective efficacy, which is a group’s sense of its ability to achieve a specific objective, assists understanding of community readiness and households’ decisions to take preparedness actions. Collective efficacy expands the concept of social capital, which refers to social resources such as trust, norms and networks, by addressing how likely communities are to activate these resources for specific tasks. This paper empirically investigates the effect of three distinct collective efficacy components on risk perception, fear and self-efficacy regarding natural hazards in Austria. The three components have differing impacts on risk and coping beliefs: (1) Social cohesion decreases risk perception and fear but has no effect on self-efficacy; (2) Efficacy belief in social support increases self-efficacy; (3) Efficacy belief in citizen groups increases risk perception and fear. The combination of efficacy belief in social support and citizen groups seems to be most promising for stimulating protective action, as they together promote both risk and coping appraisal. However, overreliance on social support may have the undesirable effect of creating a false sense of safety among disaster-prone households. The findings demonstrate that collective efficacy provides a meaningful perspective from which to examine risk and coping beliefs but caution against treating it as an umbrella concept, given the differing effects of its components. Future studies are needed to investigate the impact of collective efficacy on other key explanatory factors of protective action, such as response efficacy or non-protective responses.     

A characterisation of the methodology of qualitative research on the nature of perceived risk: trends and omissions

The issue of how risk is ‘perceived’ is one of significant research interest and immense practical importance. In spite of this wide interest, however, it is probably fair to say that most emerging ‘risk’ crises – whether related to natural or technological phenomena – come as a surprise to researchers and to society as a whole. Prediction of human responses to novel potential hazards (or novel manifestations of old hazards) is neither reliable nor complete; strategies to ameliorate inappropriate concerns when they arise (or to make realistic inappropriate absences of concern) do not appear totally effective. It therefore seems apt to ask the question: just what have we learned about ‘risk perception’? In this paper we conduct a structured review of qualitative research on perceived risk – to be followed by a subsequent analysis of quantitative research in a later paper – focusing upon methodological issues. Qualitative research often precedes quantitative research, and ideally informs it; it seeks depth and meaning from few subjects rather than identifying patterns within larger samples and populations. Without adequate qualitative research, quantitative research risks misanalysis of the target phenomenon, at the very least by the omission of relevant factors and inclusion of irrelevant ones. Our analysis here – of qualitative studies conducted across a range of disciplines, not all of which will be familiar to the readers of this journal – suggests that this research suffers from an incomplete coverage of the ‘risk perception universe’, typified by a focus on atypical hazards and study samples. We summarise the results of this research, while pointing out its limitations, and draw conclusions about future priorities for research of this type.     

Traffic risk perception,road safety attitudes,and behaviors among road users: a comparison of Turkey and Norway

The present study aims to investigate differences in road safety attitudes, driver behavior, and traffic risk perception between Turkey and Norway. A questionnaire survey was conducted among a sample of Norwegian (n?=?247) and Turkish (n?=?213) road users. The results show that Turkish respondents perceived traffic risk to be higher than Norwegian respondents. Turkish respondents reported safer attitudes towards drinking and driving than Norwegian respondents, while Norwegians reported safer attitudes towards speeding. Turkish respondents reported a lower frequency of speeding behaviors than Norwegian respondents, whereas Norwegian respondents reported a lower frequency of drinking and driving. Traffic risk perception was related to road safety attitudes and behaviors among Norwegian respondents but not among Turkish respondents. The results were discussed with respect to differences in traffic safety, traffic culture, and the development levels in Turkey and Norway.     

The determinants of integrating policy-based and community-based adaptation into coastal hazard risk management: a resilience approach

Abstract

A growing number of studies focus on improving the understanding of how the households’ adaptations can be encouraged in the process of coastal hazards and risk management. Particularly, this process is undergoing a major paradigm shift as it moves from an approach dominated by policy-based adaptation to another one in which community-based resilience building is favored. Thus, this article aims to apply a resilience approach to improve the knowledge about how public measures influence private autonomous adaptation behavior, through a transdisciplinary investigation of household adaptation behavior and its determinants. The Resilience Framework of Household Autonomous Adaptation to Climate- and Weather-Related Hazard Risks (ROHACHR) is proposed and combined with a focus group meeting and multivariate analysis to compare pre-disaster, during a disaster, post-disaster adaptations, and resilience behavior of households. Using an empirical survey of the households in three coastal municipalities in Taiwan, we examine the relationships between public measures and private adaptations that provides three distinguishing types of household behavior: ‘core’, ‘trust in governmental aid’, and ‘awareness and structures’. Results show that providing hazard risk information may be one step toward encouraging private autonomous adaptations. Several factors that help foster resilience also appear to be influential in households’ adaptation decisions, such as specific and positive governmental aid, information trust, and social capital. Based on these results, it shows that the ROHACHR is useful to characterize households’ adaptation and resilience behavior and explain how they respond to public measures. Finally, the policy implications of our findings for improving resilience of coastal communities and encouraging public-private collaboration in the process of hazard risk management are discussed.     

Corporate social responsibility and firm financial risk reduction: On the moderating role of the legal environment

Approaching the institutional environment through its regulative component, we distinguish between shareholder‐oriented and stakeholder‐oriented countries. Identifying first this classification with the distinction between common law versus civil law countries and using a large sample of 5,716 firm‐year observations that represents 1,169 individual firms in 25 countries between 2001 and 2011, we show that Corporate Social Responsibility (CSR) significantly reduces firms’ idiosyncratic risk in civil law countries but not in common law countries. Using then a more direct classification based on shareholder and employee protection scores, our findings suggest that CSR negatively affects firms’ idiosyncratic and systematic risks only in less shareholder‐oriented and more stakeholder‐oriented countries, respectively. These findings are similar in the different components of CSR with two notable exceptions: a high score in corporate governance reduces firm risk only in common law countries, and community involvement increases idiosyncratic risk in more shareholder‐oriented and less stakeholder‐oriented countries, respectively. Taken together, our results strongly support the view that the relationship between CSR and financial risk is moderated by the institutional context of the firm.     

The influence of linear and cyclical temporal representations on risk perception of nuclear waste: an experimental study

Time is an important aspect of the issue of nuclear waste, both from a technical and from a perceptional perspective. Previous studies have investigated the relationship between time and risk perception of nuclear waste, applying the discounting paradigm and therefore limiting time to one very narrow aspect: its duration. However, time is a multifaceted concept and encompasses more than a linear property. The aim of our study is to test the influence of a different aspect of time, namely temporal representations (linear or cyclical) on risk perception of nuclear waste. In an experimental study we demonstrate that both linear and cyclical representations have a reducing effect on risk perception compared to the control condition, where no specific time representation was activated. Examining group differences, we also demonstrate that temporal representations have a differing influence depending on whether participants have a stable belief about nuclear waste or whether they belong to an ambivalent group that does not yet hold a stable belief. Furthermore, we replicate the well-documented gender gap in risk perception. Our results bear potentially interesting implications for risk communication by demonstrating a causal relationship between the graphic representation of time and risk perception of nuclear waste.     

College,mental health,and a violent student: employing numerical formats to communicate risk on campus

Abstract

Non-experts, including college administrators, professors, and students are often faced with risk assessment decisions on campus. Despite this fact, there are few accepted professional standards for presenting statistical risk and far fewer recommendations for the communication of violence risk. Existing systematic reviews are both incomplete and limited in scope and more troubling are the contradictory conclusions and competing recommendations for the communication of information that is essential to decision-making. In this article, three directions in the violence risk communication literature were given attention. First, non-experts were asked to make risk estimates using information from an expert source. Second, this project moves research attention to an important domain, campus violence. Finally, multiple outcome variables were assessed in an effort to extend the scope of research beyond Bayesian reasoning. Measured outcomes included: risk judgments, linguistic features, and affective processing as put forth by the affective processing theories. When the effect of estimating or communicating risk as a probability was compared to a frequency: frequency evidence was rated as less confusing and easier to understand.
