Deconstruction of the discourse authority of scientists in Chinese online science communication: Investigation of citizen science communicators on Chinese knowledge sharing networks.

This article explores science communication and discussion about genetically modified food on Zhihu, the biggest Chinese knowledge-sharing social network, through the methods of online ethnography and discourse analysis. The long-term online ethnography finds a new group emerging: citizen science communicators - those members of the public without a professional scientific background who actively assume the role of communicators. The discoursal and behavioural characteristics of citizen science communicators effectively eliminate the boundaries between scientists and the public, scientific discourse and that of non-scientists, as well as the 'exclusive legitimacy' of science and scientists in the online science communication process. By eliminating boundaries and 'exclusive legitimacy', the authority of Chinese scientists has also been challenged and deconstructed in online science communication on Zhihu.
