Physician and bioethicist
Genetic information plays an increasingly prominent role in society. Think, for example, of testing for genetic disorders, identifying crime suspects, or discovering your ancestry with a commercial DNA test. In various societal contexts, this raises different ethical questions. These questions become even more complex as data moves from one context to another. What if, for example, the police search a commercial DNA database to track down a suspect?
I did my PhD research at the Department of Philosophy at VU Amsterdam. The first part of the research focused on the ethics of tracking down crime suspects using non-forensic DNA databases, such as medical biobanks in hospitals and commercial DNA platforms.
Complex issues
A bioethical approach, focused on individual autonomy and privacy, proved too limited to address these complex issues. Genetic data is, by its nature, shared data: we share half of our DNA with our parents, children, brothers or sisters, and smaller portions with other close and distant relatives. If one person gives permission to share their genetic data, data about others will inevitably be revealed as well.
"In today's age of Big Data and AI, there is growing criticism of the narrow focus on individual privacy and autonomy."
"Accept all cookies"
Therefore, the second part of the research focuses on the lessons we can learn from data ethics. In today's age of Big Data and AI, there is growing criticism of the narrow focus on individual privacy and autonomy, where a simple click on an “accept all cookies” button will not protect our fundamental rights.
Draw important lessons
Bioethics can draw important lessons from these developments in data ethics in the debate around genetic data. Examples include relational approaches to privacy and autonomy and the risks of commodification. A broader socio-political reflection on these themes can help shift the debate on genetic data from the individual (literally indivisible) to a ‘dividual’: a ‘shared self’.
