Frames of scientific evidence: How journalists represent the (un)certainty of molecular medicine in science television programs

For laypeople, media coverage of science on television is a gateway to scientific issues. Defining scientific evidence is central to the field of science, but there are still questions if news coverage of science represents scientific research findings as certain or uncertain. The framing approach is a suitable framework to classify different media representations; it is applied here to investigate the frames of scientific evidence in film clips (n = 207) taken from science television programs. Molecular medicine is the domain of interest for this analysis, due to its high proportion of uncertain and conflicting research findings and risks. The results indicate that television clips vary in their coverage of scientific evidence of molecular medicine. Four frames were found: Scientific Uncertainty and Controversy, Scientifically Certain Data, Everyday Medical Risks, and Conflicting Scientific Evidence. They differ in their way of framing scientific evidence and risks of molecular medicine.

Science journalists' selection criteria and depiction of nanotechnology in German media

For lay people, mass media are the main source of scientific information; that is why science journalists’ selection and depiction of scientific issues is an important field to study. This paper investigates science journalists’ general issue selection and additionally focuses on science journalists’ depiction of nanoscale science and technology and its related scientific evidence (certainty/uncertainty of research findings). Face-to-face interviews with science journalists (n = 21) from different German media channels were conducted. The results show that the professional role conception, personal interest, news factors and organizational processes mainly influence the selection of science journalists. Overall, journalists have increasingly positive attitudes towards nanoscale science and technology. But results indicate that the coverage of scientific evidence differs according to the science journalists’ focus on beneficial or risky aspects of this emerging technology: journalists stress scientific uncertainty predominantly when discussing the risks of nanoscale science and

Promises and reservations towards science and technology among South African publics: A culture-sensitive approach

Against the background that surveys measuring public perceptions of science and technology are often removed from cultural contexts and do not equally represent all regions of the world, this study investigated attitudes towards science and technology among different publics of the South African population. To apply a culture-sensitive approach, theoretical considerations of cultural distance were combined with methodological considerations of segmentation studies, and representative data (n = 3183) were reanalysed. The findings show that six South African publics can be distinguished, and that – despite the fact that all publics see more promises of science than reservations – there tend to be sensitive differences between these publics. In the long run, such findings might help to make science communication more effective.

Scientific evidence and mass media: Investigating the journalistic intention to represent scientific uncertainty

Science journalists are responsible for the mass media’s representation of life sciences (e.g. biotechnology, genetics, and nanotechnology) and for the depiction of research findings in these areas as more scientifically (un)certain. Although researchers have determined that the representational styles of scientific evidence vary among science journalists, the reasons for these differences have not yet been fully investigated. Against this background, for the first time, the present study applies a reasoned action approach and investigates the predictors of the journalistic intention to represent scientific uncertainty, using computer-assisted telephone interviews with a representative sample of German science journalists (n = 202). The results indicate that beliefs about the coverage of other media, perceptions regarding scientific uncertainty of the main field of coverage, perceived expectations of the audience, past behavior, and gender were the predictors that most strongly affected the journalists’ intention to represent life sciences as more scientifically uncertain.

(Un)Certainty in the News Journalists’ Decisions on Communicating the Scientific Evidence of Nanotechnology

Science journalists are responsible for the media content about nanoscale science and technology, and its representation as scientifically certain or uncertain. This article applies the reasoned action approach (RAA) to identify factors having an impact on journalists’ decisions on how to depict aspects of scientific evidence (= scientific (un)certainty). Results of interviews with science journalists (n = 21) from diverse media channels showed that they adopt different coverage styles when representing (un)certainty. To find reasons for that, behavioral, normative, and control beliefs were investigated, and a model of science journalistic depiction behavior with respect to scientific evidence was constructed.

Eyes on the frame: Explaining people’s online searching behavior in response to TV consumption

Purpose Using the internet parallel to or after television (TV) consumption changes the way people receive news. The way information is framed by the media has been found to influence the behavior of news recipients. The purpose of this paper is to hypothesize that the exposure to TV media frames would affect a lay audience’s online information-seeking behavior. Design/methodology/approach In an experiment combining eye tracking and content analysis, participants (n=72) were exposed to one of three TV clips with different media frames (based on a full-sample content analysis) that focused on Alzheimer’s disease. After exposure, participants informed themselves about the issue online. Eye tracking allows to investigate whether individuals mainly scan information, or whether they compute information on a higher level of attention (use more thorough deliberate comparison of information and really reading information). Findings Three different frames of online content were identified. Framing was found to influence the individual online searching and reading of information on a descriptive level (entering search words and viewing website content) to some degree, but not on a procedural level (such as selecting online search results). Research limitations/implications This study makes a significant contribution to the literature embedding an established theoretical process like framing effects into the internet literature. Regarding the broader theoretical context, this study shed some light on cross-media framing effects on online behavior. Applying the psychological perspective of framing theory to explain and predict online searching behavior is beneficial for specific types of online search behavior. Main limitations are the not representative student sample and the forced task that participants had to inform themselves about Alzheimer’s disease online. Practical implications The results have practical implications for the creation of TV-related websites. There can be a positive, profitable synergy of TV and online websites. The websites can complement the TV programs with the focus on information needs of the recipients depending on the TV activated audience frames. Therefore, media managers would do well to plan the contents of their websites as internet-based resources that meet the activated information needs. Originality/value This study is among the first to investigate the framing effects of TV on the online information searching behavior of individuals. A deeper understanding of how media frames, especially from TV, are affecting online information seeking will allow researchers to better explain and predict online user behavior and information needs. But still, more research is needed.

Effects of Valenced Media Frames of Cancer Diagnoses and Therapies: Quantifying the Transformation and Establishing of Evaluative Schemas

Journalists portray health issues within different frames, which may shape news recipients’ evaluations, attitudes, and behaviors. As the research on framing continues to face theoretical challenges and methodological concerns, this study examines the transformation and establishing of evaluative schemas, which are steps in the process toward attitudinal change. The study measures recipients’ evaluations of actual television clips dealing with cancer diagnoses and cancer therapies. Two valenced (positive vs. negative) media frames were tested in a 3-week online panel (n = 298) using a pretest–posttest design with a German sample. The results offer limited support for the hypothesis that media frames transform participants’ schemas, but do not support the hypothesis that new schemas are established in response to media frames. The study also investigates interactions between framing and participants’ issue involvement, as well as between framing and topic-specific interest and media use.

“Science is Everywhere, but No One Knows It”: Assessing the Cultural Distance to Science of Rural South African Publics

ABSTRACT In science communication, a prerequisite for reaching different parts of a society is to find out how these publics experience and interpret science. Since rural South African publics are perceived to exhibit a large cultural distance to science, the present exploratory study aimed to know in more detail how rural South Africans perceive and understand science in their local and social contexts. Theoretical notions on cultural distance and the methodological approach of segmentation studies were considered. Semi-structured interviews with rural South Africans were carried out in four towns (n = 52) that differ with respect to having a large scientific installation in their vicinity, or not. Sensitively comparing local and social contexts helped identifying three different publics who differed regarding their perceptions of science; however, the large scientific installations only made a difference in perceptions for those publics who were generally less exposed to and less knowledgeable about science.

The Question of Newsworthiness: A Cross-Comparison Among Science Journalists’ Selection Criteria in Argentina, France, and Germany

Although science journalists’ selection criteria have been investigated, there have not been systematic attempts yet to study how this varies across countries. Using gatekeeping theory, we analyzed and compared how three groups of journalists in Argentina, France, and Germany selected their news, and explored some motivations behind their decisions. Personal interests as well as a set of common news factors and sources are important for all journalists, while the journalists differ regarding professional role conceptions, the influence of their organizations, and perceived importance of audience perceptions. More research is needed to unravel science news selection criteria across different journalistic cultures.

The Draw-a-Scientist Test in an African context: comparing students’ (stereotypical) images of scientists across university faculties

Abstract Background: People’s perceptions of scientists have repeatedly been investigated using the Draw-a-Scientist Test (DAST). The test is used to identify people’s (stereotypical) images of scientists, which might affect attitudes towards science and science-related career choices. Purpose: The current study has two goals. (1) Applying the DAST at a university in South Africa, the study will add to the existing research literature through its Southern African context. (2) The study will also look more closely at the link between (stereotypical) images of scientists and science-related career choices. Sample: The DAST was applied to first-year students (n = 445) across different faculties at a South African university. If the assumption that young people’s perceptions of scientists influence their career choice is correct, one would expect differences in the drawings made by students who have opted for different fields of study. Design and methods: The DAST was administered during orientation week of the first-year students in January 2017. Students were provided with a prepared blank sheet of paper and asked to draw a scientist and to fill in further information on the back of the paper. A content analysis applying the DAST checklist was used to analyse the images. Results: The findings show that South African students use about four stereotypical indicators when drawing a scientist, and social science students drew stereotypical attributes more frequently when compared to students from other faculties. A typical scientist – as depicted in this study – is a man of uncertain age, who wears eyeglasses and a lab coat, and is surrounded by laboratory equipment. Conclusions: Findings are largely in line with the international research literature. To challenge gender stereotypes, more contact between students and female role models might be essential. If (stereotypical) images really affect science-related career choices deserves further attention in future research studies.
