 When, if ever, is a person authorized to waive her informed consent rights? Should participants who donate blood in a medical trial be permitted to authorize its use in any future trial, without their specific consent for each token (as U.S. federal regulations allow them, since 2018, to do)? What about a patient or a candidate study participant who asks to be spared tedious descriptions of her different options, and would rather entrust the medical team, or her village elder, with key decisions? What about someone who asks her physician to lie to her, if he is willing, should her prognosis be despairing? And what about a woman who would like to sell pregnancy services with a fully enforceable contract to hand over the baby even if she develops strong maternal feelings toward him or her and seeks to revoke her consent?
