Trust and Betrayal in the Medical Marketplace

The author argues in this Comment that disingenuity as first resort is an unwise approach to the conflict between our ex ante and our later, illness-endangered selves. Not only does rationing by tacit deceit raise a host of moral problems, it will not work, over the long haul, because markets reward deceit\u27s unmasking. The honesty about clinical limit-setting that some bioethicists urge may not be fully within our reach. But more candor is possible than we now achieve, and the more conscious we are about decisions to impose limits, the more inclined we will be to accept them without experiencing betrayal

Ethics of e-voting: an essay on requirements and values in Internet elections

In this paper, we investigate ethical issues involved in the development and implementation of Internet voting technology. From a phenomenological perspective, we describe how voting via the Internet mediates the relation between people and democracy. In this relation, trust plays a major role. The dynamics of trust in the relation between people and their world forms the basis for our analysis of the ethical issues involved. First, we consider established principles of voting, confirming the identity of our democracy, which function as expectations in current experiments with online voting in the Netherlands. We investigate whether and how Internet voting can meet these expectations and thereby earn trust, based on the experiments in the Netherlands. We identify major challenges, and provide a basis for ethical and political discussion on these issues, especially the changed relation between public and private. If we decide that we want to vote via the Internet, more practical matters come into play in the implementation of the technology. The choices involved here are discussed in relation to the mediating role of concrete voting technologies in the relation between citizen and state

Interpreting Trust: Abstract and Personal Trust for People Who Need Interpreters to Access Services

This article looks at the political and conceptual process of trust drawing on a research project exploring the experiences of people who speak little English and thus need interpreters in order to access services. We examine posited solidarity/diversity tensions in the politicisation of notions of general social trust, and debates about the process of trust, including distinctions between abstract and personal trust, the role of familiarity, and the concept of 'active trust', as well as challenges to the functional link between interpretation and expectation in trust. We address the increasing professionalisation of interpreting service provision based on abstract trust, and use case studies to illustrate the complexity of the articulation of trust in interpreters, often involving personal trust, as well as strategies for managing distrust. We conclude that, while trust may be a personal praxis, it takes place in a particular socio-political context that involves asymmetrical relations that focus on particular, minority ethnic, groups.Interpreters, Professionalisation, Solidarity/diversity, Trust

Salvage: Gendered Violence in Activist Communities

How to best deal with sexual violence in radical social movements is a contentious issue in the UK Left. The persistence of and inability to deal with sexual violence contradicts the core values of equality and social justice at the heart of radical social movements. A legacy of being marginalised and subjected to state repression and scrutiny has led radical activist communities to develop important self-protective strategies to establish trust and belonging. Safer spaces policies, transformative justice and community accountability processes have been attempted to address gendered violence without recourse to the state. Debate has focused on the effectiveness and negative impacts of these interventions often at the expense of survivors and anti-violence activists. However, safer spaces policies and accountability processes are set up to fail without a critical exploration of wider power relations and self-protective cultural practices that already frame activist communities. We chose to develop knowledge and understanding about gendered violence in activist communities from the perspectives and experiences of survivors. Our project has a particular focus on exploring the experiences of women, transgender and non-binary individuals. August 2015 and January 2016 we interviewed 10 survivors who had experienced sexual violence within a range of different activist groups and communities across the UK. These accounts map out how layers of silence and denial can work in activist groups and communities to allow and maintain violence, abuse and harm. There was little evidence of a ‘one size fits all’ solution. Instead there is a need to better recognise how intersections of cissexism, homophobia, classism, racism, sexism and ableism shape survivors’ experiences and meanings of harm, available resources and solutions, and impacts of harm on individuals and communities. Understanding what can produce a ‘conducive context’ for sexual violence against women, transgender and non-binary individuals in activism offers crucial clues in how we can undo these harms. Progressive change requires no less than a reconceptualisation of culture that recognises violence as embedded in an ongoing struggle for power and control of activist arenas

Trust networks for recommender systems

Recommender systems use information about their user’s profiles and relationships to suggest items that might be of interest to them. Recommenders that incorporate a social trust network among their users have the potential to make more personalized recommendations compared to traditional systems, provided they succeed in utilizing the additional (dis)trust information to their advantage. Such trust-enhanced recommenders consist of two main components: recommendation technologies and trust metrics (techniques which aim to estimate the trust between two unknown users.) We introduce a new bilattice-based model that considers trust and distrust as two different but dependent components, and study the accompanying trust metrics. Two of their key building blocks are trust propagation and aggregation. If user a wants to form an opinion about an unknown user x, a can contact one of his acquaintances, who can contact another one, etc., until a user is reached who is connected with x (propagation). Since a will often contact several persons, one also needs a mechanism to combine the trust scores that result from several propagation paths (aggregation). We introduce new fuzzy logic propagation operators and focus on the potential of OWA strategies and the effect of knowledge defects. Our experiments demonstrate that propagators that actively incorporate distrust are more accurate than standard approaches, and that new aggregators result in better predictions than purely bilattice-based operators. In the second part of the dissertation, we focus on the application of trust networks in recommender systems. After the introduction of a new detection measure for controversial items, we show that trust-based approaches are more effective than baselines. We also propose a new algorithm that achieves an immediate high coverage while the accuracy remains adequate. Furthermore, we also provide the first experimental study on the potential of distrust in a memory-based collaborative filtering recommendation process. Finally, we also study the user cold start problem; we propose to identify key figures in the network, and to suggest them as possible connection points for newcomers. Our experiments show that it is much more beneficial for a new user to connect to an identified key figure instead of making random connections

Public health reasoning: a logical view of trust

The public has a pact with the experts who deliver public health. That pact can be characterized as a relationship of trust in which the public trusts health experts to act in its best interests in return for its adherence to recommendations and other advice. This relationship clearly has emotional elements, as evidenced by strong feelings of anger and betrayal when public health recommendations are shown to be wrong. But it also has rational or logical components which are less often acknowledged by commentators. In this paper, these components are examined with special emphasis on the role of authority arguments in mediating the trust relationship between health experts and the public. It is contended that these arguments function as cognitive heuristics in that they facilitate decision-making in the absence of expert knowledge. A questionnaire study of public health reasoning was conducted in 879 members of the public. Participants were asked to consider a number of public health scenarios in which various arguments from authority were employed. Epistemic conditions, known to be associated with the rational warrant of these arguments, were systematically varied across these scenarios. Quantitative and qualitative data analyses revealed that subjects are adept at recognizing the conditions under which arguments from authority are more or less rationally warranted. The trust relationship at the heart of public health has logical components which lay people are capable of rationally evaluating during public health deliberations. This rational capacity should be exploited by experts during public health communication

The ethics of sociocultural risk research

In socio-cultural risk research, an epistemological tension often follows if real hazards in the world are juxtaposed against the essentially socially constructed nature of all risk. In this editorial, we consider how this paradox is manifest at a practical level in a number of ethical dilemmas for the risk researcher. (1) In terms of strategies for seeking informed consent, and for addressing the power inequalities involved in interpretative and analytical work, researchers can find themselves pushing at the boundaries of standard understandings of ethical practices and ways of engaging informants in their studies. (2) Impact on participants is another key area of concern, since the subject matter on which data are collected in risk research may be a source of uncertainty, anxiety or unwanted self knowledge. (3) Risk researchers also face the possibility of institutional repercussions of raising risk issues with people who usually normalize the risks, thereby stimulating distrust in the institutions or organizations with formal responsibilities for risk management. There are no simple formulae to guide the researcher in dealing with such ethical issues and paradoxes. It is important, though, to recognize their specificity in risk studies, including the ambiguous status of questions about vulnerability since judgements about 'who is vulnerable' and 'in what ways' are themselves influenced by the situational framings and understandings of participants and researchers
