Keyes [2004, p. 15] says: “In the post-truth era we don't just have truth or lies but a third category of ambiguous statements that are not exactly the truth but fall short of a lie”. In this paper about Hector's and Maui dolphin management in New Zealand, we argue that some scientific knowledge about these species presented and disseminated in ways that equate to this third category and as such may be classed as ‘post-truth type communication’. This generates citizen mistrust in science, scientists and government agencies and inflames conflict among informed stakeholders. We argue trust may be rebuilt by a combination of deliberative approaches to environmental governance, transparency about uncertainties, information gaps and divergent scientific opinions, and reformulation of normal scientific approaches and assumptions to those advocated by post-normal science.

‘Catan’® (1995) is a multiplayer tabletop game with global sales of over 20 million copies. Presented here is an exploration of the steps that were taken in the development of the ‘Catan: Global Warming’ expansion, from prototype to final design. During the playtesting of the game the feedback that we received from a variety of playtesters indicated that the game mechanics (rather than any accompanying story) were an effective and elegant way of developing dialogue around a specific topic, in this instance global warming. We conclude that in order to develop such a game, consideration must be given to: the accessibility of the game, the game literacy of the proposed players, the playtesting of the game mechanics, the peer review of the scientific content, and the extent to which the metagame (i.e. those discussions that take place around and away from the game) is enabled.

Knowing how specific publics understand and experience science is crucial for both researchers and practitioners. As learning and meaning-making develop over time, depending on a combination of factors, creative possibilities to analyze those processes are needed to improve evaluation of science communication practices. We examine how first grade children's drawings expressed their perceptions of the Sun and explore their views of a major astronomical body within their social, cultural and personal worlds. We then examine how the observation of the Sun through a telescope led to changes in graphical representations, and how learning and meaning evolved after several months.

This critical discourse analysis examined climate change denial books intended for children and parents as examples of pseudo-educational materials reproduced within the conservative echo chamber in the United States. Guided by previous excavations in climate change denial discourses, we identified different types of skepticism, policy frames, contested scientific knowledge, and uncertainty appeals. Findings identify the ways these children's books introduced a logic of non-problematicity about environmental problems bolstered by contradictory forms of climate change skepticism and polarizing social-conflict frames. These results pose pedagogical dilemmas for educators, environmental advocates, and communication experts interested in advancing understanding and action in the face of rapid climate change.

Astronomy has been an inherently visual area of science for millenia, yet a majority of its significant discoveries take place in wavelengths beyond human vision. There are many people, including those with low or no vision, who cannot participate fully in such discoveries if visual media is the primary communication mechanism. Numerous efforts have worked to address equity of accessibility to such knowledge sharing, such as through the creation of three-dimensional (3D) printed data sets. This paper describes progress made through technological and programmatic developments in tactile 3D models using NASA's Chandra X-ray Observatory to improve access to data.

This study explores the field of scientific policy advice in environmental and energy policies in France to gain insights into the role of think tanks. The field evolved along with the growth of think tanks. The think tanks refer to several orders of worth and combine them in their communication in order to qualify their expertise. The results of the study reveal that the think tanks have become more independent actors and that the field of scientific policy advice has gained autonomy. Both aspects indicate that the relationship between politics and expertise has gradually changed in France.

This study investigates how different segments of the public, with varying degrees of interest in S&T, could formulate opinions on a broader vision and the role they think STI should play in Japanese society through 2020 (Tokyo's Olympic and Paralympic year) and toward 2030. We conducted nine inclusive public engagement activities. Results indicated that the broad public opinions did not completely overlap with officials' opinions, a value of “open and appropriate” was mainly found from the unengaged public, and the visions and values based on their opinions could well be incorporated into the official document. Engaging the disinterested in S&T remains an issue.

Currently in Spain, there is a political and social debate over the use and sale of homeopathic products, which is promoted mainly by the skeptical movement. For the first time, this issue has become significant in political discourse. This study analyzes the role that homeopathy-related stories are playing in that political debate. We analyzed the viewpoints of headlines between 2015 and 2017 in eight digital dailies (n = 1,683), which published over 30 stories on homeopathy during the three-year study period. The results indicated that the stance on therapy's lack of scientific evidence gained ground during the period studied.

The study contributes to mediatization research. Mediatization is understood as a process during which individual and collective actors adapt towards the demands of publicity and public attention. The manuscript introduces a differentiation of mediatization strategies, ranging from defensive to offensive strategies. This conceptual differentiation is applied empirically regarding relevant stakeholders within the German science-policy constellation from politics, science, and science funding. Results are based on 35 in-depth interviews with decision makers. The results section deals with similarities and differences considering the mediatization of organizations, and introduces a typology of science-policy stakeholders based on the conceptual differentiation of mediatization strategies.

Today, science and politics are in a complex status of reciprocal dependency. Politics is dependent on scientific expertise in order to adequately address highly complex social problems, and science is fundamentally dependent on public funding and on political regulation. Taken together, the diverse interactions, interrelations and interdependencies of science and politics create a heterogenous and complex patchwork — namely, the science-policy interface. The societal relevance for phenomena such as scientific policy advice, science governance or (politically fostered) science communication have been amplified by the developments of digitalisation and now call for new approaches to clarify the ambiguous relationships within the science-policy interface. This special issue aims to provide a platform for researchers to address communication at the intersection of science and politics from different angles. The research presented in the special issue, thus, aims to reduce the contingency of science-policy communication in its various dimensions and looks to spur further investigations into the science-policy interface.
