Despite Australian horse owners being encouraged to vaccinate their horses against Hendra virus to reduce the risk of this potentially fatal virus to horses and humans, vaccine uptake has been slow. Discourse around the vaccine has been characterised by polarisation and dissenting voices. In this study we interviewed horse owners (N=15) and veterinarians (N=10), revealing how expert knowledge, disqualification of lay knowledge and inadequate handling of uncertainty impacted divisive discourse around Hendra virus. We assert that more inclusive, reflective and ultimately more effective risk communication practices will result if the legitimacy of diverse knowledge sources and the inevitability of uncertainty are acknowledged.

The years of the protests marked a period of social turmoil in Italy. The critical impulses that developed within worker and student groups had political effects even on science. This paper aims to offer a historiographical description of some stages of the relationship between scientists and protesting movements, going back over the developments in science communication in Italy between the late sixties and the seventies, focusing on the case of Lucio Lombardo Radice and his work as a TV populariser. The reinterpretation of the recent past could be useful to better understand the contemporary developments in science communication from a historical perspective.

This article provides a framework for analysing changes and continuities in science communication. The field is challenged by three contexts: (1) ‘post-normal situations’ of coping with uncertainties, value questions, an urgency to take action, and associated political pressures; (2) a dramatically changing media environment, and (3) a polarizing discourse culture. We refine the concept of post-normal science to make it more applicable to analyse public science communication in an era of digital media networks. Focussing on changes in the interactions between scientists and journalists, we identify two ideal types: normal and post-normal science communication, and conclude that the boundaries of science and journalism are blurring and under renegotiation. Scientists and journalists develop new shared role models, norms, and practices. Both groups are increasingly acting as advocates for common goods that emphasize the emerging norms of post-normal science communication: transparency, interpretation, advocacy and participation.

This theoretical paper proposes a framework for how citizen science can be adapted to organizational contexts. Using an “input, process, output” approach, this model proposes organizational factors (e.g., communication channels and styles, and organizational structure) that should be considered when choosing among citizen science approaches (e.g., contributory, collaborative, co-created). The essay identifies possible outcomes for the individual, organization, and larger sector from employing a citizen science approach within an organizational setting.

Blogs provide potential for publics to engage more deliberatively through dialogue in controversial science than one-way dissemination methods. This study investigated who was commenting on two antithetical climate change blogsites; how they were commenting; and the quality of their dialogue. Most research into science blogs has focused on bloggers rather than commenters. This study found that both blogsites were dominated by a small number of commenters who used contractive dialogue to promote their own views to like-minded commenters. Such blogsites are consolidating their own polarised publics rather than deliberately engaging them in climate change science.

Verbal probability phrases are often used in science communication to express estimated risks in words instead of numbers. In this study we look at how laypeople and statisticians interpret Dutch probability phrases that are regularly used in news articles. We found that there is a large variability in interpretations, even if the phrases are given in a neutral context. Also, statisticians do not agree on the interpretation of the phrases. We conclude that science communicators should be careful in using verbal probability expressions.

How a discipline's history is written shapes its identity. Accordingly, science communicators opposed to cultural exclusion may seek cross-cultural conceptualizations of science communication's past, beyond familiar narratives centred on the recent West. Here I make a case for thinking about science communication history in these broader geotemporal terms. I discuss works by historians and knowledge keepers from the Indigenous Australian Yorta Yorta Nation who describe a geological event their ancestors witnessed 30,000 ybp and communicated about over generations to the present. This is likely one of the oldest examples of science communication, warranting a prominent place in science communication histories.

This study explores the effects of food science perception on food decisions in the controversial case of genetically modified (GM) foods. We examine (1) how scientific consensus and scientific deference affect the public perception of GM foods; and (2) how perception and healthy eating interest influence people's actual food consumption decisions. We categorized our samples into four groups based on different risk/benefit perceptions of GM food: tradeoff, relaxed, skeptical, and uninterested in the process of further data analysis.

Many studies have examined the impression that the general public has of science and how this can prevent girls from choosing science fields. Using an online questionnaire, we investigated whether the public perception of several academic fields was gender-biased in Japan. First, we found the gender-bias gap in public perceptions was largest in nursing and mechanical engineering. Second, people who have a low level of egalitarian attitudes toward gender roles perceived that nursing was suitable for women. Third, people who have a low level of egalitarian attitudes perceived that many STEM fields are suitable for men. This suggests that gender-biased perceptions toward academic fields can still be found in Japan.

Public acceptance of vaccination and Genetically Modified (GM) food is low and opposition is stiff. During two science festivals in France, we discussed in small groups the scientific evidence and current consensus on the benefits of vaccination and GM food safety. Our interventions reinforced people's positive opinions on vaccination and produced a drastic positive shift of GM food opinions. Despite the controversial nature of the topics discussed, there were very few cases of backfire effects among the 175 participants who volunteered. These results should encourage scientists to engage more often with the public during science festivals, even on heated topics.
