Mitochondrial replacement in the English-language print media: continuity and change in metaphors and social representations

In May 2023, The Guardian announced that babies had been born through mitochondrial replacement therapy (MRT). MRT and its ethical and legal implications have been discussed in the media for over a decade. These discussions have been examined by social scientists and communication scholars. In this article, we seek to determine whether and, if so, how social representations have changed since this announcement. Using thematic analysis and social representations theory, we studied a corpus of 70 English language newspaper articles. Results show three thematic dichotomies: (1) moderation vs. sensationalism; (2) ontologising vs. de-ontologising MRT; and (3) using metaphors for persuasion vs. explanation. The societal concern representation largely dominated reporting around 2015 and the hope and opportunity representation was prominent in current reporting. We argue that the hope representation may facilitate greater patient and public acceptance of MRT but that it may also limit awareness, understanding and discussion of its possible risks and limitations.
