 The requirement of informed consent is often attacked on the ground that many patients would rather have physicians make certain decisions for them, and that such delegation often seems acceptable (Schneider 1998). One answer to the attack argues that informed consent is a patient’s right, not her duty (Beauchamp and Childress 2008, 105, 107), and that, since informed consent serves autonomy, it ought to be autonomously waiveable (Beauchamp and Childress 2008, 106). Indeed, autonomously signed advance directives that bind one’s future self can be perfectly consensual and autonomous. What we may call “waiveable waivers” of informed consent rights (“Please spare me the full disclosure or decide in my name unless I ask to resume full disclosure or active control”) seem relatively easy to accept and fairly consistent with autonomy. However, we do impose some rights, which we consider inalienable, on unwilling rights holders. The right not to become a slave is inalienable, and the same may apply to some informed consent rights, such as the right not to become a participant of a clinical trial that one cannot exit.
