According to the bioethical principle of individual decisional autonomy, the patient has a right of informed consent to any medical or experimental procedure. The principle is politically liberal by advocating significant individual freedom as guaranteed by law and secured by civil liberties. When practiced in illiberal communities, might it have a political liberalizing effect? I respond first by analyzing cross-national norms of individual decisional autonomy to identify tensions with illiberal community; second, by examining examining Singapore in a single case study to show that liberal bioethics does not promote political liberalization; and third, by showing that the possibility of practicing liberal bioethics in research, clinically as well as in education, does not require a democratic order, and that liberal bioethics is unlikely to encourage the liberalization of illiberal political communities. Hence, it may never contribute to the development of globally effective cross-national norms for the legal regulation of bioethical research and clinical practice. Fourth, to bolster this analysis, I anticipate several possible objections to various of its aspects.
