The authors advocate an interaction between research and policy making. Social research can best influence transplantation policies in altruistic living donation by in-depth interviews into the complicated background beliefs underlying personal preferences. In addition, the public should be encouraged to judge the immanent issues in a morally responsible way. In the end, a fair balance should be established between the impartial requirements of social justice and the partial motivations of individuals involved in altruistic living donation. Although discriminatory acts should be rejected categorically, donation policies should be willing to consider, support, and accept motivations based on personal loyalties.
