BackgroundAlthough the “right not to know” is well established in international regulations, it has been heavily debated. Ubiquitous results from extended exome and genome analysis have challenged the right not to know. American College of Medical Genetics and Genomics Recommendations urge to inform about incidental findings that pretend to be accurate and actionable. However, ample clinical cases raise the question whether these criteria are met. Many incidental findings are of uncertain significance. The eager to feedback information appears to enter the (...) field of IFUS and thereby threaten the right not to know. This makes it imperative to investigate the arguments for and against a right not to know for IFUS.DiscussionThis article investigates how the various arguments for and against a right not to know hold for IFUS. The main investigated arguments are: hypothetical utilitarianism, the right-based argument, the feasibility argument, the value of knowledge argument, the argument from lost significance, the empirical argument, the duty to disclose argument, the avoiding harm argument; the argument from principle, from autonomy, from privacy, as well as the argument from the right to an open future. The analysis shows that both sides in the debate have exaggerated the importance of incidental findings.SummaryOpponents of a right not to know have exaggerated the importance of IFUS, while proponents have exaggerated the need to be protected from something that is not knowledge. Hence, to know or not to know is not the question. The question is whether we should be able to stay ignorant of incidental findings of uncertain significance, if we want to. The answer is yes: As long as the information is not accurate and/or actionable: ignorance is bliss. When answering questions that are not asked, we need to think twice. (shrink)

Individual autonomy is a concept highly appreciated in modern Western societies. Its significance is reflected by the central importance and broad use of the model of informed consent in all fields of medicine. In predictive genetic testing, individual autonomy gains particular importance, for what is in focus here is not so much a concrete medical treatment but rather options for taking preventive measures and the influence that the test results have on long-term lifestyle and preferences. Based on an analysis of (...) autonomy-related issues in predictive genetic diagnosis and genetic screening programmes, this contribution stresses the central relevance of a broad notion of autonomy for the discussion of ethical issues raised in connection with predictive genetic testing and genetic screening programmes. Only against the background of such a broad notion of autonomy, which stresses not only free and informed decision-making but also the relevance of long-term prospects for leading a self-determined life in familial and social contexts, can the manifold autonomy-related issues linked to predictive genetic testing be given adequate consideration.
