While there has been much interest in this topic, no generally accepted definition of dual use has been forthcoming. As a contribution to this issue, it is maintained that three related kinds of things comprise the category of dual use: research, technologies and artefacts. In regard to all three kinds, difficulties are identified in making clear distinctions between those that are and are not dual use. It is suggested that our classification should take account of actual capacities and willingness to (...) make use of these objects for ‘bad ends’ and not the mere possibility that this could be done, and here three ‘contextual factors’ are identified. A (provisional) definition is proposed that takes account of threats and risks. (shrink)

The dual-use dilemma arises in the context of research in the biological and other sciences as a consequence of the fact that one and the same piece of scientific research sometimes has the potential to be used for bad as well as good purposes. It is an ethical dilemma since it is about promoting good in the context of the potential for also causing harm, e.g., the promotion of health in the context of providing the wherewithal for the killing of (...) innocents. It is an ethical dilemma for the researcher because of the potential actions of others, e.g., malevolent non-researchers who might steal dangerous biological agents, or make use of the original researcher’s work. And it is a dilemma for governments concerned with the security of their citizens, as well as their health. In this article we construct a taxonomy of types of “experiments of concern” in the biological sciences, and thereby map the terrain of ethical risk. We then provide a series of analyses of the ethical problems and considerations at issue in the dual-use dilemma, including the impermissibility of certain kinds of research and possible restrictions on dissemination of research results given the risks to health and security. Finally, we explore the main available institutional responses to some of the specific ethical problems posed by the dual-use dilemma in the biological sciences. (shrink)
