AbstractLock-in is defined as the tendency to continue with an inefficient decision or project proposal. The front-end phase is critical to project success, yet most studies have focused on lock-in in the implementation phase. Moreover, little is known about the way in which decision-makers perceive the risk of lock-in. In this paper we identify determinants of lock-in in the front-end phase and we reveal decision-makers’ perceptions of risk of lock-in. Our findings show that risk attitudes towards lock-in vary with the level of risk aversion. However, this is not sufficiently acute to drive the level of regret needed to avoid lock-in. This implies that decision-makers do not accurately assess the risk of lock-in and as such their risk perceptions are a mediating factor in the formation of lock-in. Based on escalation of commitment, path dependency, and prospect theory, the main contribution lies in providing a more comprehensive understanding of lock-in in the front-end phase.

Background Understanding COVID-19 risk perceptions and their impact on behaviour can improve the effectiveness of public health strategies in the future. Prior evidence suggests that, when people perceive uncontrollable risks to their health, they are less likely to make efforts to protect their health in those ways which they can control (e.g. through diet, exercise, and limiting alcohol intake). It is therefore important to understand the extent to which the threat of COVID-19 is perceived to be an uncontrollable risk, and to assess whether this perceived risk is associated with differences in health behaviour. MethodsWe surveyed a nationally representative sample of 496 participants, shortly after the peak of the pandemic in the UK. We collected data to assess people’s perceptions of COVID-19-related risk, and how these perceptions were associated with behaviours. We examined self-reported adherence to behaviours recommended by the UK Government and National Health Service to prevent the spread of the virus, as well as more general health behaviours. We predicted that increased perceived extrinsic mortality risk (the portion of a person’s mortality risk which they perceive to be uncontrollable) would disincentivise healthy behaviour. ResultsPerceived threat to life was found to be the most consistent predictor of reported adherence to measures designed to prevent the spread of infection. Perceived extrinsic mortality risk was found to have increased due to the pandemic, and was also associated with lower reported adherence to Government advice on diet and physical activity, as well as smoking. ConclusionsOur findings suggest that promoting a message that highlights threat to life may be effective in raising levels of adherence to measures of infection control, but may also have unintended consequences, leading to a reduction in health-promoting behaviours. We suggest that messages that highlight threat to life should be accompanied by statements of efficacy, and that messages evoking feelings of concern for others may also be effective in promoting compliance with anti-infection measures.

The risks faced by customers when using the services of LPD, with attention to and maintain the quality of the company provided to customers will be added value to the LPD. The purpose of this study to determine the effect of service quality on the perception of customer value mediated by risk perception. This research was conducted at LPD Pererenan Kabupaten Badung. The sample used is 100 customers. The technique of this research is purposive sampling and analysis technique used is path analysis technique. Quality of service has a positive and significant impact on the perception of value. Perceptions of risk have a negative and significant impact on the perception of value, which means that when perceived risk perceptions of customers when using LPD services are high, the perception of customer value on LPD is low. Service quality has a negative and significant impact on risk perception. Perceptions of risk mediate the effect of service quality on the perception of customer value positively and significantly, it proves when the quality of service and perception of customer value is high then customer risk perceptions aat using LPD services low. A good LPD business should be able to maintain the quality of service provided to its customers, in terms of service. LPDs should be able to prioritize the interests of LPD customers in financial services LPD, able to establish good service quality and perception of good customer value.   Keywords: service quality, customer perception, risk perception

Perceived risk is an important component of technology acceptance and adoption. Research has explored perceived risk, and its relation to technology acceptance. However, only limited work has considered common technologies, or assessed different types of risk. This study explored perceptions of risk within 5 types (financial, performance, physical, psychological, social) and overall perceived risk, for 23 common technologies. 178 participants rated the technologies across all the types of risk. In general, the technologies were rated as mildly risky for all categories of risk, but ratings were even lower for psychological, physical, and social risk. However, individual technologies varied in their rankings. This study emphasizes the need to understand not just overall perceived risk, but also type of perceived risk. This insight can assist developers and others (e.g., marketers) to understand what types of risk must be mitigated through redesign, training, or other means to promote technology acceptance.

Since the middle of the 20th century, perceptions of risk have been critical to understanding engagement in volitional behavior change. However, theoretical and empirical risk perception research seldom considers the possibility that risk perceptions do not simply exist: They must be formed. Thus, some people may not have formulated a perception of risk for a hazard at the time a researcher asks them, or they may not be confident in the extent to which their perception matches reality. We describe a decade-long research program that investigates the possibility that some people may genuinely not know their risk of even well-publicized hazards. We demonstrate that indications of not knowing (i.e., “don’t know” responses) are prevalent in the U.S. population, are systematically more likely to occur among marginalized sociodemographic groups, and are associated with less engagement in protective health behaviors. “Don’t know” responses are likely indications of genuinely limited knowledge and therefore may indicate populations in need of targeted intervention. This body of research suggests that not allowing participants to indicate their uncertainty may threaten the validity and generalizability of behavior-change research. We provide concrete recommendations for scientists to allow participants to express uncertainty and to analyze the resulting data.

The degree of caution that people are willing to take for a given product is largely determined by their perceptions of the risk associated with that product. Research suggests that risk perceptions are determined by the objective likelihood or probability of encountering potential hazards (Slovic, Fischhoff, and Lichtenstein, 1979). However, there is also research suggesting that objective likelihood plays little or no role in determining risk perceptions. Rather, risk is determined by the subjective dimension of the hazard or in other words, the severity of injury (Wogalter, Desaulniers and Brelsford, 1986, 1987). The present research examined aspects of these two studies in an attempt to reconcile the observed differences. Subjects evaluated either the Wogalter et al. (1986, 1987) products or the Slovic et al. (1979) items on eight rating questions. Results demonstrated that severity of injury was the foremost predictor of perceived risk for the Wogalter products, but that likelihood of injury was primarily responsible for ratings of risk for the Slovic items. The two lists differed substantially on all the dimensions evaluated, suggesting that the content of the lists is responsible for the contrary findings. In a second study, subjects rated another set of generic consumer products. These ratings showed a pattern of results similar to the Wogalter products. Overall, this research: (a) explains the basis for conflicting results in the risk perception literature, and (b) demonstrates that severity of injury, and not likelihood of injury, is the primary determinant of people's perceptions of risk for common consumer products.

AbstractThis paper studies the economic effects of testing during the outbreak of a novel epidemic disease. I propose a model where testing permits isolation of the infected and provides agents with information about the prevalence and lethality of the disease. Additional testing reduces the perceived lethality of the disease, but might increase the perceived risk of infection. As a result, more testing could increase the perceived risk of dying from the disease - i.e. “stoke fear” - and cause a fall in economic activity, despite improving health outcomes. Two main insights emerge. First, increased testing is beneficial to the economy and pays for itself if performed at a sufficiently large scale, but not necessarily otherwise. Second, heterogeneous risk perceptions across age-groups can have important aggregate consequences. For a SARS-CoV-2 calibration of the model, heterogeneous risk perceptions across young and old individuals mitigate GDP losses by 50% and reduce the death toll by 30% relative to a scenario in which all individuals have the same perceptions of risk.

ObjectivesFood technologies have facilitated a healthier, more efficient, and sustainable food supply. They nevertheless often face resistance from consumers. Compared to organic and traditional farming techniques, food produced with technologies tends to be associated with higher perceptions of risk, lower attitudes, and fewer perceived benefits. Countering resistance toward technologies poses a serious challenge because persuasive appeals have the potential to amplify preexisting attitudes instead of changing them. We tested six infographics for their ability to improve attitudes and risk perception toward six food technologies: hormones, antibiotics, GM crops, vaccines, sustainability technology, and animal welfare technology. Our objective was to determine whether these infographics would successfully shift perceived risk and attitudes toward these technologies.Materials and MethodsParticipants (n = 810) from English speaking countries (in North America, Europe, and Australia) were recruited from Amazon’s MTurk service. They answered a survey assessing their levels of risk perception and attitudes regarding each of the six food technologies, followed by a general food technology neophobia (FTN) survey. An experimental condition (n = 416) saw an infographic before answering questions about each technology and a control condition (n = 394) did not. Linear mixed effects models implemented in R were used to test risk and attitude differences among technologies and whether the infographics affected risk perception and attitudes.ResultsLinear mixed effects models revealed that there was a significant interaction between technology and condition for both risk: F(54040) = 5.068, p < 0.001, and attitudes: F(54040) = 26.34, p < 0.001. Overall, there was a tendency for risk perception to decrease (g = –.36, z = 6.89, p < 0.001) and attitudes to increase (g = .48, z = 9.38, p < 0.001), in the condition that saw the infographics. However, there were larger decreases in risk perception and increases in attitudes for hormones (risk: z = 5.05, p < 0.001; attitudes: z = 8.30, p < 0.001), GMOs (risk: z = 6.89, p < 0.001; attitudes: 13.21, p < 0.001), vaccines (risk: z = 6.45, p < 0.001; attitudes: z = 6.11, p < 0.001), and antibiotics (risk: 5.06, p < 0.001; attitudes: z = 7.83, p < 0.001), but smaller changes for sustainability (risk: z = 2.77, p = 0.03; attitudes: z = 2.89, p = 0.02) and animal welfare (risk: z = 4.91, p < 0.001; attitudes: z = 3.51, p = 0.003). Including FTN in the models did not affect the overall pattern of results, suggesting that the changes in risk perception and attitudes were not due to simply a general change in FTN.ConclusionOur results found that infographics provide a potential avenue for improving attitudes and risk perception for food technologies. Across six different infographics, we found attitudes and risk perception improved for hormones, antibiotics, vaccines, GMOs, sustainability technologies, and animal welfare technologies. These results are important because such persuasive appeals can often backfire, yet here we observed general improvement. In future studies it will be critical to examine how such attitude and risk perception changes relate to consumer behavior (e.g., willingness-to-pay), and which specific strategies in the infographics led to the improved attitudes.

The purpose of this study was to analyze a model of online tour package purchasing behavior which is influenced by the perceptual aspects of review ratings, perceived risk, trust and purchase intention. The research design used a combination of exploratory, descriptive-quantitative research. The population and sample selection uses consumers in West Jakarta who will purchase tour packages online. Determining the number of samples using purposive sampling technique and will be distributed to 203 consumers. These findings prove that the rating review positive effect on trust and perceptions of risk. Perceptions of risk have a negative effect on trust and purchase intention. Trust has a positive effect on purchase intention. This is an important consideration for business actors in making future marketing strategy decisions to achieve competitive advantage.

This study surveyed 185 parents to determine whether their perceived risk of their child developing obesity and their implicit theories about the malleability of weight independently and/or interactively predict their child-feeding and pursuit of child-related obesity risk information. Higher risk perceptions were associated with healthier feeding intentions and more information seeking. More incremental (malleable) beliefs predicted healthier feeding intentions and greater pursuit of environmental, but not genetic, information. Contrary to hypotheses, the influence of implicit theories and risk perceptions were primarily independent; however, more incremental beliefs predicted less “junk food” feeding among only parents with lower perceived risk.
