Before and after the Chinese gene-edited human babies: Multiple discourses of gene editing on social media.

This study examines discourses in Chinese online discussions of gene editing by multiple social actors on Weibo before and after a significant scientific crisis, the 2018 scandal of Chinese gene-edited human babies. A content analysis of 2074 posts was done to identify frames, emotions, and metaphors. Findings reveal that Chinese social media have opened up new spaces for multiple social actors to generate multiple discourses. This has resulted in a more participatory public engagement with science and technology on Chinese social media, potentially influencing the online agenda and policy decisions on science and technology. Finally, findings indicate that a scientific crisis can serve as a trigger for significant changes in public attitudes and opinions regarding gene editing.
