REDSSA Conceptual Team​​

The REDSSA Conceptual group aims to develop normative and conceptual research projects on the ethical, legal and social issues (ELSI) in data science in sub-Saharan Africa. By 'normative research', we refer to a critical investigation into what should (or should not) be done in the conduct of data science, including descriptions of different positions on specific topics (such as consent for the use of phylogenetic data) and nuanced discussions of the strengths and challenges of such positions. By 'conceptual research', we refer to a systematic historical, cultural and philosophical inquiry into the origins, meanings and implications of concepts used to understand the world, in this case, the world of data science. Our specific focus will be largely on concepts central to ethical discussions in data science, such as (data sharing) obligations, individual and group privacy, anonymization, and 'data justice'. The group starts from the assumption that ethical concepts are value-laden, that the implicit values are not necessarily universal, and therefore, attention will be given to local cultural significance embedded in concepts such as 'data.' We thereby aim to contribute to the creation of a conceptual ELSI framework for data science, as well as illuminating and informing empirical ELSI work conducted by the REDSSA project.
