Ordinary ethics: lay people's deliberations on social sex selection

This article summarises the results of a research project that used a scenario about sex selection of embryos for social reasons as a basis for discussion groups with lay people. The aim of the research was to examine the processes by which non-professionals make ethical evaluations in relation to a contested area in medical genetics. We note in particular the role played in the discussions by expressions of instinct; making distinctions; rational argument; reference to principles; use of personal experience; analogies and examples; slippery slope arguments and meta-reflections. The implications for developing processes of public consultation and debate are also considered.
