Responsibility in the life sciences: assessing the role of professional codes

In response to threats from bioweapons, questions are being asked today in some countries about the implications and appropriateness of biological research. Many organizations and governments have suggested that bioscientists adopt what is generally referred to as a "code of conduct" to reduce the security concerns associated with their work. This article examines the potential contribution of such codes. By drawing on past lessons in other areas of professional life, it suggests some key questions, issues, and dilemmas for future consideration. As argued, attempts to establish codes must address demanding questions about their aims and audience--questions whose answers depend on potentially contentious issues regarding arms control, science, ethics, and politics.
