The essential decision in sequential choice is not which alternative to choose but when to stop acquiring additional information and commit to the leading alternative. Two studies investigate individuals’ stopping strategies. The key difference between the two studies is whether the experimenter or subjects controlled the order in which information was acquired. We hypothesize that subjects’ stopping criteria do not remain fixed, but are sensitive to acquisition costs and to the achieved progress during the choice. Across both studies 21 of 26 subjects exhibited significant adaptation. We also found an effort-reducing heuristic, stopping after all attributes in a predetermined set of core attributes had been acquired. As expected, use of this Core Attributes heuristic was greater when subjects controlled the order in which information was acquired. Both adaptation and the Core Attributes heuristic are compatible with the adaptive view of decision making and with the cost-benefit framework more generally. 相似文献

The conception of social justice as equality is defended in this paper by examining what may appear to be two inegalitarian
conceptions of justice, as distribution according to desert and as distribution according to need. It is argued that claims
of just entitlement arise within a context of reciprocal co-operation for mutual benefit. Within such a context there are
special cases where it can be said that those who contribute more deserve more, and that those who need more should get more,
but those claims themselves presuppose a norm of equal contribution and equal benefit.

One of the arguments against conducting human subject trials inthe Third World adopts a distributive justice principle found ina commentary of the CIOM'S Eighth Guideline for internationalresearch on human subjects. Critics argue that non-participantmembers of the community in which the trials are conducted areexploited because sponsoring agencies do not ensure that theproducts developed have been made reasonably available to theseindividuals.I argue that the distributive principle's wording is too vagueand ambiguous to be used to criticize any trial. Furthermore,the mere fact that an experiment does not fulfill this particulardistributive justice principle does not entail that it isunethical. 相似文献

Several nation states have reasons to halt the import of genetically modified organisms. The current international trend towards a regime of free trade makes such bans problematic. Whether a nation state is deemed justified in banning a certain product is strongly connected to discussions about what are acceptable criteria for proof of risk. The determination of these criteria hinges upon considerations of individual and national autonomy. This paper compares two different points of view in the debate: the WTO opposed to the UN. A distinction between internal and external autonomy explains the differences in approach between the UN and the WTO. The conclusion is reached that adequate respect for autonomy requires a certain amount of flexibility in the criteria for proof of risk. 相似文献

Mainstream moral theories deal with situations in which the outcome of each possible action is well-determined and knowable. In order to make ethics relevant for problems of risk and uncertainty, moral theories have to be extended so that they cover actions whose outcomes are not determinable beforehand. One approach to this extension problem is to develop methods for appraising probabilistic combinations of outcomes. This approach is investigated and shown not to solve the problem. An alternative approach is then developed. Its starting-point is that everyone has a prima facie moral right not to be exposed to risk. However, this right can be overridden if the risk-exposure is part of an equitable system for risk-taking that works to the advantage of the individual risk-exposed person. 相似文献

abstract The question of when it is permissible to inflict risks on others without their consent is one that we all face in our everyday lives, but which is often brought to our attention in contexts of technological innovation and scientific uncertainty. Xenotransplantation, the transplantation of organs or tissues from animals to humans, has the potential to save or improve the lives of many patients but gives rise to the possibility of infectious agents being transferred from donor animals into the human population. As well as being an important ethical issue in its own right it therefore provides a useful vehicle for exploring the more general question of how to balance the benefits of a practice against the risks to third parties. This paper focuses on the Rawlsian, justice-based analysis of the risks of xenotransplantation proposed by Robert Veatch. It argues that Veatch is right to take considerations of distributive justice into account, but that his particular approach is flawed. It is hoped that consideration of Veatch's arguments, and of the underlying assumptions will suggest better ways of executing a justice-based approach. 相似文献

There are certain kinds of risk for which governments, rather than individual actors, are increasingly held responsible. This
article discusses how regulatory institutions can ensure an equitable distribution of risk between various groups such as
rich and poor, and present and future generations. It focuses on cases of risk associated with technological and biotechnological
innovation. After discussing various possibilities and difficulties of distribution, this article proposes a non-welfarist
understanding of risk as a burden of cooperation. 相似文献

Systemic financial risk is one of the most significant collective action problems facing societies. The G reat R ecession brought attention to a tragedy of the commons in capital markets, in which market participants, from the first‐time homebuyer to W all S treet financiers, acted in ways beneficial to themselves individually, but which together caused substantial collective harm. Two kinds of risk are at play in complex chains of transactions in financial markets: ordinary market risk and systemic risk. Two moral questions are relevant in such cases. First, from the standpoint of interactional morality, does a person have a moral duty to avoid risk of harm to others if their financial transactions contribute in some way, however small, to the loss or harm? This article identifies the conditions in which persons are morally responsible in such cases. Second, from the standpoint of institutional morality, how should society distribute the risk of harm associated with massively complex financial markets? This question is considered in the context of the home mortgage credit market. Luck egalitarianism, in particular a D workinian insurance scheme to allocate risks and resources relating to mortgage credit and private home ownership, offers substantial promise. 相似文献

Researchers must provide participants with opportunities to make informed decisions about whether to participate in research studies. Investigators conducting research with youth in the juvenile justice system face unique ethical, legal, and practical challenges to obtaining informed consent. Juvenile justice researchers must navigate multiple legal and ethical standards for collecting informed consent, take into account youths’ dual vulnerabilities as children and prisoners, and overcome practical limitations to obtaining parental/guardian permission. Given the challenges and complexity of obtaining standard informed consent of youth in juvenile justice facilities, this paper provides suggestions for overcoming obstacles to recruiting these youth for research participation. It offers guidance for fostering the enrollment of juvenile justice youth in research studies using procedures that comply with ethical and legal standards for research with this dually vulnerable population.

The Ethics of Immigration is a wonderfully comprehensive and insightful journey through all the major contemporary ethical issues concerning immigration. Through this outstandingly well‐crafted work, Carens builds a compelling case for many important positions on how we should treat migrants. Nevertheless, I believe there are some tensions in his arguments that could do with more analysis. I present some of these issues in this article. These include some important problems with arguments for the right to education for children of irregular migrants and those concerning admission, his general position on refugees, and his views about what is required in order to treat temporary workers fairly. 相似文献

Bauer, Taub, and Parsi's review of an international sample of standards on informed consent, confidentiality, commercialization, and quality of research in tissue banking reveals that no clear national or international consensus exists for these issues. The authors' response to the lack of uniformity in the meaning, scope, and ethical significance of the policies they examined is to call for the creation of uniform ethical guidelines. This raises questions about whether harmonization should consist of voluntary international standards or international regulations that include an official oversight mechanism and sanctions for noncompliance, and about who should participate in the harmonization process. Moreover, the normative assumptions and political dynamics that shape global policymaking need to be addressed. This commentary explores the policy implications and normative questions raised by the idea of international ethical guidelines for the use of biotechnologies and biotechnological resources such as stored samples of human tissue. 相似文献

The Effects of Participation in Goal Setting and Goal Rationales on Goal Commitment: An Exploration of Justice Mediators 总被引:1,自引:0,他引:1
The interactive effect of participation in goal setting and goal rationales on goal commitment was examined in the present study. Two justice mediation models that might explain these effects were also hypothesized. The results of a laboratory study demonstrated that goal rationales were especially important for increasing goal commitment when goals were assigned rather than participatively set. Support was also found for the role of interactional justice in mediating the effect of goal rationales on goal commitment; however, the hypothesis that procedural justice would mediate the effect of goal participation on goal commitment was not supported. 相似文献
