Ethical issues in research with human subjects.

It is obvious that many disciplines confront ethical problems in research in which situational details may vary, but in which the same ethical principles may prevail. I write not in order to propose a definitive set of rules but to demonstrate how situations posing ethical problems can be reduced and more readily resolved by rational analysis of underlying issues and principles; I hope to stimulate further analysis and dialogue. It might be particularly helpful if researchers in a wide range of disciplines contributed experiences permitting a sharpening of guidelines. Finally, it is conceivable that a code of ethics might eventually be promulgated by a supradisciplinary body such as the AAAS, and that such a code could then be adapted and adopted by other scientific bodies and professional organizations-even by specific agencies such as research institutes, clinics, institutions, and schools.
