Comments on a paper by Peter Brown, "Informed Consent in Social Experimentation," given at a Conference on Moral, Ethical, and Legal Issues of Social Experimentation. In Brown's analysis of the role of informed consent in social experiments, he has argued first that a certain type of person exists for whom the consent doctrine is inappropriate; these people are either not sufficiently perceptive or too poor to make wise decisions. Brown's second point is that nonparticipants in the experiment who are affected by it ought to have the right to disapprove of it, and ,if the experiment proceeds, ought to be compensated. The author disputes these arguments. 11 pp. Bibliog.
