This study investigated public trust and its determinants concerning the government's control of tobacco in Japan. We focused on the two issues of government policies to ban smoking by minors and increase taxes on tobacco. We conducted a questionnaire survey in which respondents were asked to assess their trust in the government, the government's fairness and competency, and their value similarity with the government. One thousand three hundred and ninety‐four respondents agreed to participate in the survey out of 2,600 randomly sampled adults over 20 years old from all over Japan. The results of multiple regression analysis confirmed that value similarity is the strongest predictor of public trust in the government. On the affirmatively supported issue of prohibiting smoking among minors, the results further indicated that assessment of competency is a stronger predictor than assessment of fairness. In contrast, assessment of fairness is a stronger predictor than assessment of competency for the still divided issue of increasing tobacco tax. Respondents who had low concern and had not formed clear opinions on the issues showed a weak link between assessment of value similarity and trust. Based on these findings, we considered the implications for the government's implementation of tobacco controls.

Do the results of a scientific study influence confidence in the study's validity and the magnitude of change in the resulting perceived danger of the health risk investigated? Findings from the three investigations reported here indicate that scientific results that confirm a danger (negative results) do affect confidence in a study's validity and resulting risk assessments differently than results indicating low risk (positive results). Findings of Study 1 revealed that research results indicating a health risk were more trusted than results indicating little health risk. This effect was independent of the credibility of the information source. Study 2 demonstrated that confidence in research results increased with an increasing indication of health risk. Study 3 showed that people have more confidence in the results of animal tests on a food additive indicating negative human health effects than in animal tests indicating that a food additive is harmless. The findings have important practical implications. The observed asymmetry between positive and negative research results may be one reason that people are afraid of many of the hazards they are faced with in modern society.

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 knowledge about a hazard and therefore does not need to rely on managing authorities, social trust is unrelated to judged risks and benefits. Participants (N = 91) assessed risks, benefits, and trust in managing authorities and personal knowledge associated with 25 hazardous technologies and activities. As expected, strong correlations between social trust and judged risks and benefits were observed for hazards about which people did not possess much knowledge. No significant correlations between social trust and judged risks and benefits were found for hazards about which people were knowledgeable. Results suggest that the lay public relies on social trust when making judgments of risks and benefits when personal knowledge about a hazard is lacking. Replicating findings of other studies, the present study also found negative correlations between perceived risks and perceived benefits. When social trust was controlled for, correlations between perceived risks and benefits diminished. Implications of the results for risk management are discussed.

Social trust is a crucial issue to many aspects of modern society. Policy makers continually aspire to winning it and corporations frequently run the risk of losing it. The 'trust deficit' raises vital questions and problems to which until recently there have been few answers or solutions.Experts from both sides of the Atlantic explore the importance for trust of various influences, from individual perceptions to organizational systems, and consider the conditions involved in building or undermining trust. Several authors examine practical hazard management issues, including medical vaccinatio

Using quantitative analysis of questionnaire responses, observations during focus group discussions, and qualitative assessment of discussion statements, the present study examined trust and social representations of the U.S. Forest Service's management of Southern California national forests for the protection of endangered species. Supporting expectations based on the salient values similarity (SVS) model, it was found that (a) trust was highly correlated to assessments of shared salient values, and (b) trust and both the evaluation and acceptance of specific forest management practices were strongly related. Four patterns of social representations of shared value saliency and trust of U.S. Forest Service forest management to protect species were identified. Results demonstrate the importance of trust to the acceptance of forest management practices. They also suggest the need to recognize the influence of perceived variations in saliency of values in the SVS model.

Most cultural approaches to risk management deal with the connections between the forms of social relations within groups and the risk concerns of those groups. According to these theories, a certain limited set of different relational forms (usually three, four, or five) lead to specific, different and conflicting, risk concerns. In contrast to these theories, cosmopolitanism is an approach to culture that focuses, not on forms of sociality, but on changes among forms—expansions and contractions in the inclusivity of forms and movement by persons from one form of sociality to another. Relative to other cultural theories, cosmopolitanism thus is much more concerned with the solution of risk management problems than with their origins. Cosmopolitanism can be thought of as a cultural continuum, with cosmopolitanism at one end and pluralism at the other. Cosmopolitan persons are more open to cultural change—and thus the solution of risk management problems. In this article, we outline our new theory of cosmopolitanism, describe a method for measuring it and present an experimental study that tests some implications of the theory. Results from the study support the theory by showing that, compared to pluralistic respondents, cosmopolitan respondents are more inclusive in their risk management judgments—that is, they express equal concern for a local and a national issue, whereas the pluralistic respondents express greater concern in the local case. We discuss the risk management implications of a cosmopolitan approach to culture.

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 Zürich students indicated that the proposed causal model explained perception of pesticides, nuclear power, and artificial sweetener very well. When social trust was controlled, the relation between risks and benefits perceived diminished. Results indicate that social trust is a key predictive factor of the perceived risks and benefits of a technology, and provide support for the salient values similarity theory of social trust.

Extensive scientific investigations often fail to identify specific carcinogens that have caused geographic clusters of cancer cases. In many such examples, public health officials and other experts have concluded that the cluster is not the result of a particular local environmental condition. Despite this conclusion by experts, concerned members of local communities often persist in believing that the cancer cluster was not random. The present study accounts for the persistence of this belief on the basis of two factors: (a) the tendency of the human mind to identify patterns (and causes), rather than randomness; and (b) a lack of social trust in public health experts. It was expected that perceived shared values evoke social trust. Individuals who conclude that public health experts share their values should be more likely to accept the experts' conclusion that a cancer cluster reflects randomness, not a particular local cause. Individuals who trust authorities should be more inclined than individuals not having trust to accept that a geographic cluster of cancer cases is a coincidence. Data from Swiss students (N= 334) supported these expectations. Additionally, significant gender differences were observed. Females had less trust in authorities and perceived the cancer cluster as less likely to be a result of pure chance than did males. Practical implications of the results are discussed.
