Public acceptance of meat-reduction policies across cultures
Purpose As meat-reduction policies are discussed across the globe, many are met with public resistance. Cultural values may help explain this pushback, yet their role in shaping support for food policy remains poorly understood. This study is the first to apply cultural cognition theory to food policy by examining how cultural worldviews shape the acceptance of meat-reduction interventions in Singapore and Switzerland—two economically developed c…
The impact of information on fossil fuel beliefs and risk-benefit perception
Cultured meat
Since cultured meat is often framed as a more ethical alternative to conventional livestock farming, the question arises of whether it also appeals to vegetarians. To explore this, our study is among the first to examine cultured meat acceptance in a large vegetarian sample (n = 282) while using an equally sized omnivore group (n = 284) as a reference. This online study's participants were Germans aged 18 to 35. We compared both groups in terms o…
Consumer acceptance of different protein sources for meat alternatives
A wide variety of alternative proteins have been proposed for use in meat alternatives; however, it is not known how their acceptance by consumers compares. In this study, the most promising protein sources for meat alternatives in terms of consumer acceptance were identified across four European countries. An online survey was conducted among meat-eating participants in Germany (n = 472), Finland (n = 495), Italy (n = 498), and Serbia (n = 488).…
From store to home
Feeding habits established during infancy play a significant role in shaping neural and physical development as well as future food preferences, emphasizing the importance of careful food selection during this time. This study examines the reasons driving parents' choices of commercial snacks for their infants amid growing concerns over their nutritional content. Semi-structured interviews were conducted with 22 parents of infants and toddlers ag…
Consumer support of policy measures to increase sustainability in food consumption
Complementary feeding challenges
Parents play a crucial role in deciding what foods to introduce to their infants during the transition from milk to solids. This study examined the challenges they face, including adherence to official complementary feeding recommendations and the struggles and concerns across different stages of feeding. Specifically, this study focused on the initial stage (transition from breastmilk/formula to mashed foods), middle stage (consumption of mashed…
Consumers’ categorizations of dairy products and plant-based milk, yogurt, and cheese alternatives
Plant-based dairy alternatives have many benefits in terms of sustainability, animal welfare, and health, but they can only be successful in the market if consumers perceive them as suitable substitutes for conventional dairy. Consumers' expectations for new products are strongly influenced by the food categories into which they place these products. The present study aims to reveal consumers' categorizations of plant-based dairy products to gain…
Anthropomorphism – a double edged sword
Anthropomorphism, the attribution of human-like qualities to non-human entities, can influence comprehension of the surrounding world. Going beyond previous research on the general assessment of anthropomorphism, the current study aimed to explore how anthropomorphising a specific animal species influences public acceptance of livestock keeping practices. Specifically, we focused on welfare-infringing practices that limit animals’ freedom, descri…
A questionnaire for quality control in postgraduate medical education in Switzerland
BACKGROUND: To ensure high qualification standards in medical institutions, a questionnaire has been developed to evaluate the postgraduate medical education in Switzerland. AIM: This article describes the development and longitudinal analysis of a questionnaire using eight scales to assess the quality of postgraduate medical education. METHOD: The questionnaire has been administered to all residents every year since 2003. In 2020, 8,745 resident…
Selling, buying and eating – a synthesis study on dietary patterns across language regions in Switzerland
Purpose Cross-cultural studies on differences in eating and consumer behavior have several limitations due to differences between countries, for example, in national health policies. Switzerland combines cultural diversity between the language regions, but with a common national health policy. Therefore, Switzerland provides an ideal framework to investigate cross-cultural eating and consumer behavior. The aim of this study was to combine food co…
How health warning labels on wine and vodka bottles influence perceived risk, rejection, and acceptance
Perceived risk is an important determinant of drinking behavior, and our results suggest that HWLs may be unable to alter risk perceptions. Furthermore, a strong belief in the health benefits of alcohol consumption, particularly wine consumption, reduce risk perceptions and may be unaffected by HWLs
The drivers and barriers of wearing a facemask during the Sars-CoV-2 pandemic in Switzerland
Encouraging people to wear a facemask in situations where social distance is not possible is a relatively low-cost and low-impact measure to protect people from infections with SARS-CoV-2. Thus, the present study investigated various barriers and drivers regarding people’s self-reported wearing of protective facemasks in mandatory and non-mandatory situations. Data from a longitudinal study with four waves in Switzerland was used (N = 728). The f…
The influence of scarcity perception on people's pro-environmental behavior and their readiness to accept new sustainable technologies
Experts worldwide point to the challenges our world is facing (e.g., land degradation, resource scarcity, global warming) as described by the Intergovernmental Panel on Climate Change. Many studies have analyzed how to cope with these challenges. Aside from promoting pro-environmental behaviors, it was proposed that technological innovations might provide the potential to cope with and compensate for natural resource scarcity. We conducted an onl…
Trust and Risk Perception
Many studies in the field of risk perception and acceptance of hazards include trust as an explanatory variable. Despite this, the importance of trust has often been questioned. The relevant issue is not only whether trust is crucial but also the form of trust that people rely on in a given situation. In this review, I discuss various trust models and the relationship between trust and affect heuristics. I conclude that the importance of trust va…
The Impact of Trust and Risk Perception on the Acceptance of Measures to Reduce Covid‐19 Cases
The SARS‐CoV‐2 virus that causes COVID‐19 has had a large impact on the lives of many people worldwide. At the peak of confirmed COVID‐19 cases during the first wave in Switzerland (March–April 2020), we conducted a survey in the German‐speaking part of the country ( N = 1,585). The results suggest that the implemented measures are accepted. The survey participants are more concerned that other family members could catch the virus compared with t…
Consumers’ associations, perceptions and acceptance of meat and plant-based meat alternatives
The consumption of meat contributes significantly to undesirable effects on the environment. In order to reduce the impact of animal husbandry, one approach is to decrease meat consumption by substituting plant-based meat alternatives. Because the consumption of such meat alternatives is currently rather low, the aim of this research was to identify the barriers that keep people from consuming meat alternatives and increase the probability of fut…
Keep the status quo
Due to the increasing number of passengers at airports, regular security checks reached their capacity limits. Thus, alternative security checks are being discussed to increase their efficiency. For example, instead of screening all passengers briefly, a randomly selected sample of passengers could be screened thoroughly. However, such randomization-based security checks could be perceived as less secure based on the assumption that fewer illegal…
The influence of socio-economic status on risk prioritisation
This study examined the influence of socioeconomic status (SES) on risk prioritisation. Participants ranked 28 hazards according to how risky they considered them to be for the South African society. The results showed SES had an influence on hazard prioritisation, e.g., alcohol was considered the most significant societal hazard by low SES individuals, but was ranked 10th by high SES individuals. High SES individuals on the other hand, were sign…
A longitudinal study examining the influence of diet-related compensatory behavior on health and weight management
A longitudinal study examining the influence of diet-related compensatory behavior on healthy weight management
The aim of the present study was to examine the role of diet-related compensatory behavior in healthy weight management regarding diet quality, physical activity, and body mass index (BMI) over time in a non-clinical general population. Data were based on the first and third waves of the Swiss Food Panel 2.0 survey, which included questions about food consumption frequencies and constructs measuring weight management strategies. Data were examine…

Perception of risk
The influence of trust and confidence as personality traits on the perception of various hazards was examined. The distinction between trust and confidence is a key element of certain theories of co‐operation, but this dual‐mode approach has had little impact on empirical studies. General trust is the belief that other people can be relied on. General confidence is the conviction that everything is under control, and uncertainty is low. It was hy…

Perceived naturalness, disgust, trust and food neophobia as predictors of cultured meat acceptance in ten countries
Cultured meat is a novel food technology that promises to produce meat in a more environmentally friendly and animal-friendly way. We conducted an internet survey in ten countries (Australia, China, England, France, Germany, Mexico, South Africa, Spain, Sweden and the US) with a total sample of 6128 participants. Results suggest that there are large cultural differences regarding the acceptance of cultured meat. French consumers were significantl…

Impact of sustainability perception on consumption of organic meat and meat substitutes
How people's food disgust sensitivity shapes their eating and food behaviour
Although research regarding disgust has increased enormously in the last decades, to date there is a lack of published research about the influence of food disgust on various food-related behaviours. Our study aimed to provide an understanding about the relationships between food disgust sensitivity and eating preferences (texture-based food rejection), habits (variety seeking), and behaviours (picky eating) as well as food waste frequency. Addit…

Perception of gene technology, and food risks
Perceptions of and attitudes toward genetically engineered food and other food hazards were examined through data from telephone interviews conducted in Switzerland. A random quota sample was used ( N v = v 1001). General attitudes toward technology and political beliefs significantly influenced perceptions of gene technology. Women were more concerned about gene technology and food risks than men were. The term 'gene technology' evoked neutral o…

Development and validation of the Food Disgust Picture Scale
The present set of studies developed and tested the Food Disgust Picture Scale (FDPS). This is a tool for the assessment of food disgust sensitivity that will measure disgust and predict possible reactions. This eight-picture tool can be used in complement to or as a replacement for currently available text-based measures. In an exploratory Study 1 (N = 57), we constructed a scale consisting of eight pictures. Most of them were taken from validat…
Inner Speech as a Cognitive Process Mediating Self-Consciousness and Inhibiting Self-Deception
The cognitive processes which mediate self-consciousness are unknown. although Morin and others have suggested that inner speech may mediate self-consciousness. We developed a questionnaire which measures the extent to which one talks to oneself about oneself. As expected, the correlation between inner speech and self-consciousness was significant. A German version of the 1979 self-deception questionnaire by Sackeim and Gur correlated negatively …
A Causal Model Explaining the Perception and Acceptance of Gene Technology 1
This study examined factors affecting perceived risks and acceptance of gene technology. Based on the reviewed literature, a causal model was proposed. The plausibility of the postulated model was tested using structural equation modeling procedures. Participants were randomly selected students from a Swiss university ( N = 837). Results indicated that trust in companies and scientists performing gene manipulations have a strong effect on the ben…
Salient Value Similarity, Social Trust, and Risk/Benefit Perception
It was postulated that shared values determine social trust in institutions and persons related to a technology: One has trust in people holding similar salient values. Furthermore, it was hypothesized that social trust has a positive influence on perceived benefits and a negative impact on perceived risks. Results of a survey of University of Zurich students indicated that the proposed causal model explained perception of pesticides, nuclear pow…
Perception of Hazards
Recent research indicates that social trust of those who manage a hazard is strongly correlated to judgments about the hazard's risk and benefits. The present study investigates the more specific question of "For which hazards is this?" It was postulated that when an individual lacks knowledge about a hazard, social trust of authorities managing the hazard determines perceived risks and benefits. On the other hand, when an individual has personal…
The Influence of Trust and Perceptions of Risks and Benefits on the Acceptance of Gene Technology
A causal model explaining acceptance of gene technology was tested. It was hypothesized that trust in institutions using gene technology or using modified products has a positive impact on perceived benefit and a negative influence on perceived risk of this technology. Furthermore, perceived benefit and perceived risk determine acceptance of biotechnology. In other words, trust has an indirect influence on the acceptance of the technology. The po…
Test of a Trust and Confidence Model in the Applied Context of Electromagnetic Field (EMF) Risks
Trust is an important factor in risk management. There is little agreement among researchers, however, on how trust in risk management should be studied. Based on a comprehensive review of the trust literature a "dual-mode model of social trust and confidence" is proposed. Trust and confidence are separate but, under some circumstances, interacting sources of cooperation. Trust is based on value similarity, and confidence is based on performance.…

Flooding Risks
Experts on the risk of flooding have developed very detailed maps for different parts of Switzerland that indicate the types of damage possible and the probabilities of adverse events. Four categories of risk severity are defined on the maps, ranging from high risk to no risk. Based on these existing maps, we selected respondents for a mail survey, some from areas high in risk and others from low‐risk regions. Respondents answered several questio…
The Role of the Affect and Availability Heuristics in Risk Communication
Results of past research suggest that affect plays an important role in risk perception. Because affect may also increase the availability of risks, affect and availability are closely related concepts. Three studies tested the hypothesis that evoking negative affect (fear), either through past experience or through experimental manipulation, results in greater perceived risk. The present research focused on perception of flooding risk. Study 1 a…

Laypeople's and Experts' Perception of Nanotechnology Hazards
Public perception of nanotechnology may influence the realization of technological advances. Laypeople's ( N = 375) and experts' ( N = 46) perception of 20 different nanotechnology applications and three nonnanotechnology applications were examined. The psychometric paradigm was utilized and applications were described in short scenarios. Results showed that laypeople and experts assessed asbestos as much more risky than nanotechnology applicatio…

Natural Hazards and Motivation for Mitigation Behavior
Past research indicates that personal flood experience is an important factor in motivating mitigation behavior. It is not fully clear, however, why such experience is so important. This study tested the hypothesis that people without flooding experience underestimate the negative affect evoked by such an event. People who were affected by a severe recent flood disaster were compared with people who were not affected, but who also lived in flood-…
Precaution in Practice
Voluntary initiatives by industry have been frequently proposed as one of the most promising ways to reduce potential negative impacts on human health and the environment from nanomaterials. In this study, we examined the industrial perceptions, internal procedures, and performance of the nanomaterial industry. We conducted a written survey of 40 companies in Switzerland and Germany. Most companies replied that nanoparticulate materials (NPMs) sh…
Risk communication, prenatal screening, and prenatal diagnosis
Pregnant women's knowledge of prenatal tests was assessed in face-to-face interviews. The focus of the study was on how physicians communicate test results to their clients and whether women possess enough information to make informed decisions. Thirty-five women located in the German-speaking part of Switzerland participated in the study, which was based on half-standardized interviews lasting about an hour. Standardized questions were used to m…

Applying the evaluability principle to nutrition table information. How reference information changes people's perception of food products
Consumers often neglect or misinterpret nutrition table information. We argue in this paper that this can be explained by the evaluability principle, which posits that people's evaluation of a product corresponds to a greater degree with the product's actual value when people receive reference information about the product than when they do not get this information. We tested this assumption concerning nutrition table information in two studies. …
