This article reviews suggestions for how ethical tools are to be evaluated and argues that the concept of ethical soundness as presented by Kaiser et al. is unhelpful. Instead, it suggests that the quality of an ethical tool is determined by how well it achieves its assigned purpose. Those are different for different tools, and the article suggests a categorization of such tools into three groups. For all ethical tools, it identifies comprehensiveness and user-friendliness as crucial. For tools that have (...) reaching a decision in a democratic context as a main purpose, it identifies transparency, guiding users toward a decision and justification of the decision-supporting mechanism. For tools that aim to engage the public, it identifies procedural fairness as essential. It also notes that the scope of use for ethical tools is limited to the same moral community, and that this feature is frequently overlooked. (shrink)

The ethical matrix is a participatory tool designed to structure ethical reflection about the design, the introduction, the development or the use of technologies. Its collective implementation, in the context of participatory decision-making, has shown its potential usefulness. On the contrary, its implementation by a single researcher has not been thoroughly analyzed. The aim of this paper is precisely to assess the strength of ethical matrixes implemented by a single researcher as a tool for conceptual normative analysis related to technological (...) choices. Therefore, the ethical matrix framework is applied to the management of high-level radioactive waste, more specifically to retrievable and non-retrievable geological disposal. The results of this analysis show that the usefulness of ethical matrixes is twofold and that they provide a valuable input for further decision-making. Indeed, by using ethical matrixes, implicit ethically relevant issues were revealed—namely issues of equity associated with health impacts and differences between close and remote future generations regarding ethical impacts. Moreover, the ethical matrix framework was helpful in synthesizing and comparing systematically the ethical impacts of the technologies under scrutiny, and hence in highlighting the potential ethical conflicts.
