Tracing its historical trajectories, this article explores the preoccupation with accuracy in science communication research and explores the resurgence in the present century of concerns about accuracy, balance and impartiality in public communication of science. It is argued that many of the original insights from news and journalism research are still relevant and important if re-formulated in constructionist terms about voice, access and claims-making, and asking, in whose interest? Key to this is also the recognition of a radically changing – technologically, economically and professionally – media and communications environment, with implications for science journalism and a very different dynamic regarding the range and type of actors involved in discursively constructing opinions and information about controversial science and expertise. The article concludes with proposals for future emphases and directions in research broadly concerned with accuracy in science communication.
