This article examines the moralistic language and arguments used in relation to genetics. The focus is on three practices: (1) the claims that there is a duty to know about one’s own genetic makeup, (2) assertions that genetic information should be used to inform reproductive decisions, and (3) the proposition that there are moral reasons to participate in biobank research. With these three, the author contends that there are equally good, if not better, arguments to challenge them from a Millian perspective. Furthermore, especially in the current political climate, there is a need to respect people’s privacy concerns.
