People’s responses to risks of electromagnetic fields and trust in government policy: the role of perceived risk,benefits and control

Trust in government policy affects the way people perceive and handle risks. In our study, we investigated the relationships between trust in government policy regarding electromagnetic fields (EMF), perceived risk and perceived benefits of public and personal EMF sources, perceived control over exposure to EMF and responses to the possible EMF health risk (e.g. protest against placement of mobile phone base stations or power lines, or taking own measures against EMF exposure). Previous research indicated that perceived risk and benefits mediate the relationship between trust and people’s risk responses. Additionally, we suggest that perceived control over EMF exposure affects the relation between trust in government policy and perceived risk, and, consequently, the risk responses. We performed a survey among the Dutch population (n?=?1009), which contained questions about risk responses to EMF, perceived risk and benefits of several EMF sources, trust in government policy and perceived control over EMF exposure. Comparing public EMF sources, i.e. power lines and mobile phone base stations, to personal EMF sources, i.e. microwave ovens and cordless and mobile phones, we tested our hypotheses. Variations in risk responses to both public and personal EMF sources were mainly explained by risk perception. In addition, perceived risk partially mediated the relationship between trust in government policy and risk responses. For public sources, perceived control over exposure weakened the negative relationship between trust and perceived risk. We conclude that, especially in people with low perceived control, a lack of trust in government policy may enhance perceptions of health risks, thereby increasing their inclination for risk responses.     

Predictors of the perceived risk of climate change and preferred resource levels for climate change management programs

In a 2013 US national public opinion survey, data were collected from 1321 adult respondents for five psychometric variables – Dread, Scientists’ Level of Understanding, Public’s Level of Understanding, Number Affected, and Likelihood – for six threats (sea-level rise, increased flooding, and four others) associated with climate change. Respondents also rated perceived risk and indicated the resource level that they believed should be invested in management programs for each threat. Responses did not vary significantly across the six threats, so they were combined. The survey collected standard demographic information, as well as measuring climate change knowledge and environmental values (New Ecological Paradigm, NEP). Psychometric variables predicted perceived risk extremely well (R = .890, p < .001); all five psychometric variables were significant predictors. The results were generally consistent with previous research except that Scientists’ Level of Understanding was a positive, rather than negative, predictor of perceived risk. Jointly the demographic variables, knowledge, and environmental values significantly predicted perceived risk (R = .504, p < .001). Consistent with previous research, significant positive predictors were age, Democratic Party Identification, and NEP score; significant negative predictors were male gender and White ethnicity. When demographic variables, knowledge, and environmental values were added to psychometric ones, only the psychometric variables were statistically significant predictors. Perceived risk strongly predicted resource level (r = .772, p < .001). Adding demographic, knowledge, and environmental value variables to perceived risk as predictors of resource level did not appreciably increase overall predictive ability (r = .790, p < .001), although White ethnicity emerged as a significant negative predictor and religiosity, Democratic Party Identification, Liberal Political Ideology, and NEP score were significant positive predictors. The results demonstrate that risk perceptions of climate change and policy preferences among climate change management options are highly predictable as a function of demographic, knowledge, environmental values, and psychometric variables. Among these, psychometric variables were found to be the strongest predictors.     

Delivering vaccination messages via interactive channels: examining the interaction among threat,response efficacy,and interactivity in risk communication

New media-based interactive risk communication has gained increasing attention and importance. While extant research has focused on the main effects of interactivity on attitudinal and behavioral outcomes, little research has investigated how risk message content may interact with risk message modality such as interactivity in generating effects, or the psychological processes underlying it. In this study, we examined the interaction effect of interactivity, threat, and response efficacy on individuals’ involvement with risk message, attitudes toward vaccination, and information seeking intention in the context of meningococcal vaccination through a 2 (interactivity: low, high) × 2 (threat: low, high) × 2 (response efficacy: low, high) experiment. Results indicated a significant three-way interaction among interactivity, threat, and response efficacy on message involvement: individuals with high-threat, high-response efficacy perceptions were more involved with the message when it was presented in a more interactive modality. With high-threat, low-response efficacy, the interactive modality of the message did not influence levels of message involvement. Furthermore, message involvement mediated the effect of the three-way interaction among threat, response efficacy, and interaction on information seeking intentions. Implications for future research and practice are discussed.     

A quantitative assessment of the insider/outsider dimension of the cultural theory of risk and place

This paper examines two hypotheses of risk perception: cultural theory's distinction between insiders and outsiders and the idea that risk perceptions and their determinants differ substantially from one place to the next for the same point‐source hazard. These hypotheses are juxtaposed in cross‐tabulations and logistic regression models with competing explanations of perceived risk in communities living with technological environmental hazards: sound management, benefits, fair facility siting and sociodemographics. The data come from a telephone survey of 455 residents in Swan Hills (n = 173), Fort Assiniboine (n = 171) and Kinuso (n = 111), Alberta, Canada who are all near a large‐scale hazardous waste treatment facility. Considerable support is found for the insider/outsider thesis in terms of the highest ranked information sources and trust to ensure safety. Place differences are clear where, for example, the least facility‐related concern is in Swan Hills (31%) 12 km away, the highest is in Kinuso (81%) 70 km away and moderately high concern is in Fort Assiniboine (62%) which is also 70 km away. This study highlights the importance of fair facility siting, the need to go beyond cultural bias analysis when studying the cultural theory of risk, and suggests further exploration of the notion of tailoring risk communication that is place specific, and emphasizes channels that may be defined as ‘outsider’ and ‘insider’.     

Extrapolating understanding of food risk perceptions to emerging food safety cases

Important determinants of risk perceptions associated with foods are the extent to which the potential hazards are perceived to have technological or naturally occurring origins, together with the acute vs. chronic dimension in which the potential hazard is presented (acute or chronic). This study presents a case study analysis based on an extensive literature review examining how these hazard characteristics affect people’s risk and benefit perceptions, and associated attitudes and behaviors. The cases include E. coli incidences (outbreaks linked to fresh spinach and fenugreek sprouts), contamination of fish by environmental pollutants, (organochlorine contaminants in farmed salmon), radioactive contamination of food following a nuclear accident (the Fukushima accident in Japan), and GM salmon destined for the human food chain. The analysis of the cases over the acute vs. chronic dimension suggests that longitudinal quantification of the relationship between risk perceptions and impacts is important for both acute and chronic food safety, but this has infrequently been applied to chronic hazards. Technologies applied to food production tend to potentially be associated with higher levels of risk perception, linked to perceptions that the risk is unnatural. However, for some risks (e.g. those involving biological irreversibility), moral or ethical concerns may be more important determinants of consumer responses than risk or benefit perceptions. (Lack of) trust has been highlighted in all of the cases suggesting transparent and honest risk–benefit communications following the occurrence of a food safety incident. Implications for optimizing associated risk communication strategies, additional research linking risk perception, and other quantitative measures, including comparisons in time and space, are suggested.     

Examining inequities in children’s environmental health: results of a survey on the risk perceptions and protective actions of new mothers

Young children are more highly exposed and vulnerable to environmental health hazards than adults due to a variety of physiological and behavioural factors. Despite the significant responsibility mothers typically bear in managing their children’s health, little is known about how they perceive and negotiate these risks in their day-to-day lives. To better understand mothers’ environmental health risk perceptions and associated protective actions across socio-economic and geographic contexts, a telephone survey was conducted among new mothers (n = 606) recruited through two Public Health Units in Ontario, Canada. Analyses revealed that approximately half of the respondents were moderately or highly concerned about environmental health risks, ranging in nature from household products to outdoor air contaminants. Factors affecting the likelihood of experiencing concern included lower income and lower levels of perceived control. With regard to protective actions, 43% reported taking three or more actions to reduce environmental health risks to their children, with the likelihood of taking action being negatively affected by factors including low income and first language other than English or French, and positively affected by being a first-time parent (primiparous). This study contributes to our understanding of environmental health risk perceptions and associated protective behaviours among new mothers, and has implications for the development of more context-focused risk management and communication strategies.     

Residents’ behavioural intentions to resist the nuclear power plants in the vicinity: an application of the protective action decision model

Nuclear power is growing rapidly in China. The ultimate goal of developing nuclear power is to mitigate the energy crisis, reduce greenhouse gas emissions, and ensure sustainable economic development. However, the ‘not-in-my-backyard’ (NIMBY) attitude may influence the implementation of nuclear power projects. This study explores the determinants of behavioural intentions to resist nuclear power plants (NPPs) based on the protective action decision model (PADM). A survey of the residents (N = 432) near the Haiyang NPP significantly validated the hypothesized relations. Results suggest that information acquisition and public participation can significantly predict perceived knowledge. Perceived knowledge is important in predicting perceived benefits, NIMBY attitude, and behavioural intentions. Moreover, two inverted-U relationships for perceived knowledge with the NIMBY attitude and with behavioural intentions are observed. Furthermore, the NIMBY attitude and behavioural intentions are significantly stimulated by perceived risks, but failed to be motivated by perceived benefits. An inverted-U relationship between perceived benefits and perceived risk is also indicated. The results that the NIMBY attitude and residential distance to NPP have played significant roles in predicting behavioural intentions are obtained. Implications of our results and areas of further researches are discussed in this article as well.     

Evaluating lotteries,risks, and risk‐mitigation programs

Two experiments were designed to explore the existence of systematic differences in risk perceptions and risk attitudes between Chinese and US participants. The first experiment involved ranking monetary lotteries using measures of perceived riskiness and willingness to pay (WTP). Several simple heuristics were evaluated to predict perceived riskiness and WTP. Using WTP responses, Cumulative Prospect Theory functions were determined for participants from both countries. The second experiment involved ranking multi‐attribute real‐world risks and associated risk‐mitigation programs using measures of concern and preference, respectively. Compared to their US counterparts, Chinese participants are found to be less risk averse, more concerned about risks with higher catastrophic potential, and more in favor of risk‐mitigation programs with greater scope of benefit. The results also reveal higher within‐group agreement by Chinese participants for all tasks. For both national groups, the within‐group agreement was highest when ranking risk‐mitigation programs, but lowest when ranking lotteries with negative expected value. The implications of cross‐cultural versus cross‐task variation are discussed.     

How to trust? The importance of self‐efficacy and social trust in public responses to industrial risks

Although a great deal of research has linked both self‐efficacy and social trust to risk responses, one overlooked question concerns the association between self‐efficacy and institutional trust. The purpose of this study was to investigate the main and combined effects of trust in the self and trust in responsible agencies to affective responses and information sufficiency. Survey respondents in this study were placed into one of four categories based on their levels of self‐efficacy (high/low) and social trust (high/low), including confidence, independence, dependence and insecure groups. Based on survey data (n = 466), the accuracy of the four‐group classification was tested. Indeed, we found that our classification system correlated with responses. Both self‐efficacy and institutional trust were found to contribute to emotional risk responses, as well as risk information needs and preferences for risk information.     

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.     

Drivers of flood and climate change risk perceptions and intention to adapt: an explorative survey in coastal and delta Vietnam

Abstract

This article contributes to current research about determinants of climate change and flood risk perception, and intentions to take adaptive measures. We propose a research model that distinguishes between vulnerability and severity components of perceived risks, and adds perceived adaptive capacity as a third factor to predict the intention to take adaptive measures. We used this combined model as a conceptual lens for an explorative survey among 1086 residents of coastal and delta communities in Vietnam. Pairwise analyses revealed a significant association of flood and climate change risk perceptions with individual’s flood experience, climate change knowledge, frequency of community participation and socio-demographic factors. However, in multivariate analysis, the influence of most socio-demographic factors became weak or patchy. Flood experience was the most influential driver of flood-related risk perceptions but weak for climate change-related risk perceptions and behavioural intentions. Knowledge strongly increased the intention to adapt to flood and climate risks and the perceived vulnerability to and severity of climate change risks, but reduced the perceived capacity to adapt to climate risks. Frequency of community participation increased the perceived vulnerability and severity of climate change risks, the intention to adapt to both climate and flood risks and the perceived capacity to adapt to flood risks, but reduced the perceived capacity to adapt to climate risks. Our research confirms earlier findings that individuals’ knowledge, place-specific experience and social-cultural influences are key predictors of both flood and climate change risk perceptions and intentions to take adaptive measures. These factors should therefore receive ample attention in climate risk communication.     

Personality and domain‐specific risk taking

The concept of risk propensity has been the subject of both theoretical and empirical investigation, but with little consensus about its definition and measurement. To address this need, a new scale assessing overall risk propensity in terms of reported frequency of risk behaviours in six domains was developed and applied: recreation, health, career, finance, safety and social. The paper describes the properties of the scale and its correlates: demographic variables, biographical self‐reports, and the NEO PI‐R, a Five Factor personality inventory (N?=?2041). There are three main results. First, risk propensity has clear links with age and sex, and with objective measures of career‐related risk taking (changing jobs and setting up a business). Second, the data show risk propensity to be strongly rooted in personality. A clear Big Five pattern emerges for overall risk propensity, combining high extraversion and openness with low neuroticism, agreeableness, and conscientiousness. At the subscale level, sensation‐seeking surfaces as a key important component of risk propensity. Third, risk propensity differs markedly in its distribution across job types and business sectors. These findings are interpreted as indicating that risk takers are of three non‐exclusive types: stimulation seekers, goal achievers, and risk adapters. Only the first group is truly risk seeking, the others are more correctly viewed as risk bearers. The implications for risk research and management are discussed.     

The stability of risk and benefit perceptions: a longitudinal study assessing the perception of biotechnology

The study of public perceptions is considered to be important for making sound policy decisions, since the public decides which products will enter and sustain in the market. Stability of public perceptions is important for policy-makers; only if public attitudes and perceptions remain constant, policy-makers will be able to take them into account. The aim of the present study was to examine the stability of participants’ risk and benefit perceptions of gene technology over a period of two years. In spring, 2008 and in spring, 2010, the same sample of participants filled out an identical questionnaire. Results of structural equation modelling show that risk and benefit perceptions of gene technology applications are moderately stable (r = .5–.7). Furthermore, results show that people distinguish between medical, plant and food applications and applications involving animals when evaluating the risk of gene technology. When evaluating the benefits, participants also take consumer-related benefits into account, such as enhancement of functional properties. Results of the present study suggest that risk research should regularly examine people’s risk perceptions in order to gain a clearer picture of the dynamics of people’s perception and preferences not only of novel technologies, but also of entrenched technologies.     

Do closed survey questions overestimate public perceptions of food risks?

In this paper, we show that the widely accepted methodology for the assessment of risk perception – Likert-type survey questions featuring a set of risks with fixed response alternatives measuring the extent of worry or concern – may overestimate food risk perception. Using a European representative sample survey (n = 26,961) that included an open-ended question asking about problems and risks with food and eating, followed by a battery of closed questions (CQs) assessing food risk perception, we find a similar ranking of perceived food risks across the two methods. Across Europe, the five priority concerns are chronic food-related illness; food origins and quality; acute food-related illness; chemical contamination; and adulteration of food. However, the discrepancies between mentioning a risk in the open-ended question and the expression of worry about risks in the CQ are substantial. Of those who did not mention a specific risk category in the open question, between 60 and 83% (depending on risk category) expressed worry in the CQ. This parallels previous research on the fear of crime, showing that survey responses lead to greatly inflated estimates of the public’s fear of crime than is evidenced by qualitative questioning. It is also consistent with evidence from research on cognitive aspects of survey methodology, suggesting that survey questions may frame the respondent’s thinking about an issue. We conclude with recommendations for the use of branched questions in the quantitative elicitation of public perceptions of risk.     

Bounded rationality in credit consumers’ payment protection insurance decisions: the effect of relative cost and level of cover

A previous study found that credit consumers’ decisions to purchase payment protection insurance (PPI) were surprising insensitive to changes in cost and level of cover. This was investigated further in a randomized-groups experiment in which these two factors and the cost of credit alternatives without PPI were systematically manipulated. High street bank customers (N?=?215) were presented with realistic PPI purchase scenarios and a questionnaire assessing their willingness to pay (WTP) for PPI and perceptions of its usefulness. It was found that: (1) WTP and PPI decisions were insensitive to relatively large changes in level of cover; (2) the perceived usefulness of Premium and Basic levels of cover were not significantly different, although their usefulness was a significant predictor of PPI decisions and (3) sensitivity of PPI decisions to changes in cost was dependent on the cost of credit without PPI. The first two findings are explained in terms of simplified mental representations and the evaluability of insurance cover. It is concluded that further research on the effects of the relative cost of insurance is needed.     

Breast cancer risk perceptions and breast cancer worry: what predicts what?

This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed.     

Comparative optimism and risky road traffic behaviors among high‐risk sports practitioners

This study examines the relationship between participation in risky sports, comparative optimism (CO), and risky road traffic behaviors among a sample of adult men. We surveyed high‐risk (n = 313) and low‐risk (n = 53) sports practitioners, and non‐sportsmen (n = 89), assessing their CO, as well as their self‐reported risky behaviors and their accident experiences while driving a car. Results show that high‐risk sports practitioners expressed CO regarding the quality of their reflexes while driving and their vulnerability to traffic accidents. High‐risk sportsmen reported more risky behaviors while driving a car than the members of the other groups, and some of them, namely BASE‐jumpers, have experienced more traffic accidents. High‐risk sportsmen’s risky behaviors and accident experiences did not prevent them from expressing CO regarding their vulnerability to road accidents. Results are discussed, as well as putative psychological mechanisms underlying high‐risk sport practitioners’ CO and risky behaviors while driving.     

The effect of task-technology fit on purchase intention: The moderating role of perceived risks

Electronic commerce to date has experienced rapid growth, and online purchases have become very popular among online consumers. To successfully attract online consumers and benefit from doing so, e-tail product providers should learn about consumers’ purchase intention, its antecedents, and moderators. This study proposes a research model of purchase intention using perceived performance risk and perceived privacy risk as moderators based on a perspective of task-technology fit. In the proposed model, purchase intention is positively influenced by three antecedents: task-technology fit, perceived navigation, and perceived reputation. Each model path is moderated by perceived performance risk and perceived privacy risk, respectively. Empirically testing using a survey of 749 registered members (consumers) from the database of Taiwan’s largest e-learning commercial website confirms that task-technology fit, perceived navigation, and perceived reputation positively influence purchase intention. The relationship between task-technology fit, perceived navigation and purchase intention are significantly moderated by the perceived performance risk and perceived privacy risk. Finally, managerial implications and limitations of our findings are discussed.     

Perception of the risks and benefits of Bt eggplant by Indian farmers

Several researchers—most notably Lennart Sjoberg and his colleagues—have proposed that the moral aspects of risk provide a better explanation of risk perception than the psychometric paradigm or Cultural Theory, neither of which accounts for moral concerns. This study is possibly the first to assess empirically the perception of the risks and benefits of a transgenic food crop—transgenic Bt (Bacillus thuringiensis) eggplant—by farmers in a developing country such as India. It also aims to assess if the moral aspects of risk figure in Indian farmers' perception of Bt eggplant and if economic benefits outweigh perceived risks. To answer the research questions, a scenario was used to elicit perceptions of Bt eggplant among 100 eggplant farmers in the state of Maharashtra in India. The findings indicate that economic benefits, safety concerns, and accountability are most salient to Indian farmers' perception of the risks and benefits of Bt eggplant. Significantly, none of the farmers mentioned moral concerns as an issue. The findings also make clear that economic benefits outweigh perceived risks. This study concludes that economic benefits are more salient than moral concerns to Indian farmers' perception Bt eggplant. It also proposes that an alternative theoretical model incorporating economic benefits, safety concerns, and accountability as key variables should be developed and tested for end users in the developing world.
