The ongoing bioethical debate about organ markets rests not only on theoretical premises, but also on assumptions regarding public views of and attitudes toward organ donation that need closer socioempirical examination. Summarizing results from our previous qualitative social research in this field, this paper illustrates the ethical significance of such public moralities in two respects: On one hand, it analyzes the implicit bias of the common rhetoric of “organ scarcity” which motivates much of the commercialization debate. On the other hand, (...) it explores the blind spots of the paradigm of “altruistic donation” which informs many arguments against commercialization. We conclude that the ethical discourse has to appreciate the social nature of organ donation as a reciprocal interaction between different parties with irreducibly different but equally relevant viewpoints. We criticize the neglect of such well-founded public considerations in certain philosophical-ethical approaches and stress the need for further systematic and comparative socioempirical studies about peoples’ actual perspectives in bioethics.
