The effectiveness of a medical treatment should not predict its risk (highly effective treatments can be either safe or risky), however, people’s use of heuristic shortcuts may lead them to judge a link between effectiveness and risk, typically a negative correlation. A particular concern is that experts might use such a strategy and that this is unlikely to provide an accurate judgement. This large-scale field-based experiment compares expert-relevant and non-expert-relevant contexts, for both expert and public judgements of risk and effectiveness in the context of blood transfusion medicine. Postal questionnaires were distributed to anaesthetists (experts, N?=?123) and a general public (non-expert) comparison group (N?=?1153); half of the participants were cued with accompanying general information about genetically-modified (GM) biotechnology and half received specific information about blood product technologies. The blood-focussed information served to emphasise the medical relevance of the questionnaire to the expert group. Regression analyses showed that generally perceived effectiveness predicted perceived risk for both experts and non-experts, which suggests heuristic processing. However, although experts appeared to engage in heuristic processing for risk perceptions in certain circumstances, this processing is strongly affected by context. Experts who received the medically relevant context rated perceptions of effectiveness independently of perceptions of risk, unlike those who received the GM context. This indicates a reduced reliance on a low-effort heuristic for experts given an expertise-relevant context. The results are considered in light of dual-process (rational-associative) accounts of reasoning.  相似文献

Risk perception and risk management in Norwegian aquaculture   总被引:1,自引:0,他引:1  
This exploratory study seeks to provide empirical knowledge about fish farmers' risk attitudes, risk sources and risk management tools by presenting the results from a survey among Norwegian fish farming companies. The results show that fish farmers think of themselves as only moderately risk averse compared, for instance, to crop and livestock farmers. The most important sources of risk are considered to be future salmon prices, institutional risks and fish diseases, while keeping costs low is the most important risk management tool.  相似文献

This exploratory study investigates the risk perception and risk management strategies of Western multinational enterprises in the Middle East. A sample of 49 German companies operating in Saudi Arabia provides the empirical setting for this research. The study reveals that cultural risk is assessed as more important in the business environment than political, financial, and economic risk. The most critical risk factors are not sufficiently included in the methodology of country risk measures, which are often used as a source for country‐specific risk information. In terms of risk management strategies, participating firms use mostly informal approaches rather than structured hedging or insurance products. Furthermore, we find that firm size has implications on the perception of some risk factors and for the level of risk management sophistication.  相似文献

In 2011, Japan received a massive blow from the Tohoku Earthquake and the ensuing disaster at the Fukushima Dai-ichi Nuclear Power Generation Plant (hereafter, the Fukushima Nuclear Plant), with 18,000 people dead or missing, and more than 330,000 evacuated long-term. Anxiety among the people of Japan concerning earthquakes and nuclear accidents is higher than ever, but other hazards confront them as well. This research investigated whether the Japanese people’s anxiety about a variety of other hazards has increased or decreased since the Tohoku Earthquake. Based on the availability heuristic, the contrast effect, and the finite-pool-of-worry hypothesis, it was predicted that public anxiety about earthquakes and nuclear accidents would increase, but anxiety about other hazards would decrease. Data from two nationwide surveys conducted in January 2008 and January 2012 were compared to see the change in societal levels of anxiety toward 51 types of hazards. The results showed that anxiety had increased after the Tohoku Earthquake for only one hazard other than earthquakes and nuclear accidents. For 29 other hazards, the anxiety levels had significantly decreased; and for the remaining 19 hazards, there was no significant change. These results support the prediction, indicating that post-disaster, the overall anxiety levels of the Japanese people tended to decline. Practical implications were discussed with a focus on problems that might be caused by the changes in anxiety level.  相似文献

This paper introduces a theoretical framework that describes the importance of public's information sufficiency, risk perception, and self‐efficacy as predictors of intended risk information seeking behaviour. Based on theoretical assumptions, measurement instruments for relevant concepts were developed and validated using data from a mail questionnaire. Relationships among selected determinants of risk information seeking behaviour were analysed. Results indicate that information needs, risk perception, and current knowledge are direct predictors of intentions to seek information. Trust, engagement, social influence, and self‐efficacy affect risk perception and the need for information is influenced by engagement and social influence.  相似文献

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.  相似文献

We analyze the factors affecting farmers’ choice accounting for farm, farmer, and household characteristics as well as elicited risk perception and risk preferences. We consider three alternative hypothetical methods for assessing risk preferences to test the stability and behavioral validity of them. Our case study focuses on livestock farmers in the German region North Rhine-Westphalia. We find that risk preferences are context depending, i.e. differ across different fields of farm-level decision-making. Furthermore, our analysis shows that risk-averse farmers are more likely to prioritize on-farm risk management strategies over off-farm strategies. Moreover, higher risk perception, age, subjective numeracy, farm succession, farm size, and the proportion of rented land show a significant impact on farmers’ risk behavior  相似文献

China, as a ‘double risk’ society, is in urgent need for effective environmental risk management systems. Compared with other risks, man-made environmental risks have not been given due weight. Public awareness and perceptions of environmental risks are crucial in all phases of effective risk management. However, little is known about public perceptions of environmental risks in China. To contribute to better understanding of public perception of environmental risk, a questionnaire survey was conducted among university students in Beijing, who represent a group with high level of education and a generally high sensitivity to new information. The results show that even this group has limited knowledge about environmental risks and current risk management systems. Further studies are needed to understand the social construction of environmental risks in China and to seek ways to involve the Chinese public in emergency response and risk management.  相似文献

Concerns have been raised among policy-makers, researchers and Chinese citizens regarding the widespread environmental degradation that has occurred in China in recent decades. Years of environmental education and media coverage on pollution harm and health risks have not only provided information about pollution to the public, but have also strengthened people’s concerns. However, an ‘intense focus’ on pollution is far from sufficient; at present, it is necessary to assess to what extent the public can identify specific environmental conditions and whether they are ready to cope with potential health risks from pollution. Through face-to-face surveys on trains and at railway stations nationwide, we investigated public experiences of environmental pollution accidents, perceptions of local environmental risks (focused on air and water quality) and responses to local environmental conditions. By comparing public perceptions with official environmental monitoring data-sets, we concluded that the accuracy of perceptions related to four environmental factors ranged from 40 to 60% at the individual scale. Furthermore, the accuracies increased approximately 2–10% at the county scale and 10–30% at the city scale, highlighting the possible benefits of collective intelligence in helping the public to identify existing environment conditions more accurately. Additionally, despite great concerns about pollution and health, public attitudes toward coping with the dangers of pollution and health risks were found to be indifferent. Our study revealed factors at the individual, social and governmental levels that led to low levels of perception accuracy and response scores. Thereout, we stressed potential pathways to improve the accuracy of public perception and the positivity of responses. The survey results indicate that there is a long way to go before the public is well prepared to cope with the risks of pollution; as a consequence, it is necessary to improve both personal environmental awareness as well as governmental, social and commercial responses to pollution events.  相似文献

Process‐based considerations are generally accepted by experts and analysts as being the fundamental drivers of decision quality. However, little work has been done to account for the role of a risk management decision’s outcome as a key driver of the public judgments about decision quality. To this end, the objective of the research reported here was straightforward to determine – via an experiment – the relative importance of decision‐making process and the associated outcome in lay evaluations of decision quality. Our results demonstrate that people seem to have a difficult time unpacking decision‐making processes, even ones they strongly prefer, from their associated outcomes when evaluating decision quality. From a practical standpoint, our results cast doubt on the generally accepted belief that participatory and deliberative decision‐making processes (e.g., for risk management) will – on their own – contribute to positive evaluations of decision quality.  相似文献

The psychometric paradigm has identified two classic dimensions, dread and unknown risk, structuring the perception of risks. We propose that disputed risk and morality are two additional dimensions that are relevant to describe the cognitive representation of societal risks. Disputed risk captures two aspects of a societal risk: first, that consensus about scientific evidence is low, and second, that the public debate about the risk issue is highly controversial. Morality refers to judgments of reprehensibility, capturing the fact that societal risks frequently involve violations of moral principles. In a survey study employing two samples, a household sample (N = 418) and a student sample (N = 88), participants evaluated 24 societal risks on 23 psychometric scales intended to assess the four constructs dread, unknown risk, disputed risk, and morality. Principal component analyses yielded three dimensions: a common dimension of dread and morality, a disputed risk dimension, and unknown risk. We also assessed judgments of overall riskiness for all risks. Morality and dread both proved to be strong and distinctive predictors of perceived overall riskiness in regression analyses; disputed risk and unknown risk, in contrast, do not play a substantial role as predictors. These findings were replicated across both samples. We conclude that disputed risk constitutes a novel and unique psychometric dimension; morality, on the other hand, coincides with dread in the cognitive representation of societal risks, while still showing a distinct and strong effect in the prediction of risk judgments.  相似文献

The ‘Transmissible Spongiform Encephalopathy (TSE) Roadmap’ was published by the European Commission on 15 July 2005. The TSE Roadmap proposes the relaxation of bovine spongiform encephalopathy (BSE) measures in the short, medium and long term. According to the Roadmap, any relaxation of BSE measures following the scientific assessment should be initiated by an open discussion with all stakeholders and supported by a strong communication strategy. This paper discusses the risk perception, risk communication and risk management of TSEs in Europe, exemplified by the TSE Roadmap. The main conclusion is that in general, BSE is no longer a ‘hot’ topic for stakeholders, but there are slight differences between countries with respect to specific measures. Another important conclusion is that the TSE Roadmap is a very effective tool for risk communication with stakeholders.  相似文献

Some lay people confronted with a new base station project fear serious health consequences from the high‐frequency radiation, while experts consider exposure under the current international standards as unproblematic. These conflictive estimations may be attributed to the different mental models of lay people and experts. Less is known about lay people’s knowledge in regard to mobile communication and their intuitive understanding of the associated health risks. An adaptation of the ‘Mental Models Approach’ was used to reveal lay people’s beliefs about mobile communication and to learn more about lay people’s information requirements, potential knowledge gaps, and misconceptions. Through the means of open interviews with Swiss experts (N = 16), lay people (N = 16), and base station opponents (N = 15), different mental models were constructed and evaluated. Comparisons between the expert and the lay groups showed several qualitative differences in all identified knowledge domains. Knowledge gaps in regard to changing exposure magnitudes due to the interaction patterns of cell phones and base stations as well as misconceptions about regulation issues and scientific processes were found in both lay groups. In addition, lack of trust in responsible actors and disaffection with base station location processes were mentioned. The reported qualitative insights may be useful for the improvement of further risk communication tools.  相似文献

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.  相似文献

This study explores the influence of climate risk on properties of firms’ financial reporting practices with observations collected from 64 countries between 2005 and 2016. We use a country-level climate risk indicator developed by Germanwatch to measure the degree of damage from extreme weather events, and find that climate risk positively influences firms’ engagements in both accruals-based and real earnings management. Furthermore, we document that the above-mentioned effects of climate risk are moderated by the quality of country-level public governance. Subsample analysis suggests that the main effect of climate risk on earnings management is more pronounced for firms from developed countries, for firms in environment-sensitive industries, and for firms reporting losses. Our findings, which are supported by a battery of robustness tests, have important implication for regulators and policymakers.  相似文献

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.  相似文献

In early December 2008, a global recall of Irish pork was initiated as a result of a subset of the national pork output being contaminated with dioxin. In this study, members of a panel from an Internet‐based longitudinal monitor of public opinion on food and health issues were used to assess public perceptions about the dioxin incident in late December. Although most respondents did not regard food as posing a risk to health, a larger proportion of respondents reported that that there was a ‘very high’ health risk from pork (8.6%) compared to any other food of animal origin. However, when asked to rank the risk posed to human health from a broad range of food and non‐food hazards, PCBs/dioxins were considered to pose less of a risk than high fat food, chemical pollution, or tanning. The majority of respondents (70.5%) considered that the authorities managed the incident in an ‘adequate’ or ‘very efficient’ manner. Respondents who considered that the authorities’ management of the incident was ‘incompetent’ rated the risk associated with eating Irish pork to be higher than those who considered that the authorities’ management was ‘very efficient’. Both the European Food Safety Authority and the Irish food safety authorities pronounced that there was no risk to human health from the level of dioxin in the pork. These communications, coupled with the rapid handling of the incident in an open and transparent way, reassured consumers and maintained their confidence in the food supply.  相似文献
