This study develops a measure of perceived authenticity in science communication and then explores communication strategies to improve the perceived authenticity of a scientific message. The findings ...are consistent with literature around trust and credibility, but indicate that authenticity-the perception that the scientist is a unique individual with qualities beyond institutional affiliations or a role in the production of the research-may add a potentially important dimension to accepted categories of integrity and benevolence.

This article expands understanding of the digital divide to more nuanced measures of use by examining differences in young adults' online activities. Young adults are the most highly connected age ...group, but that does not mean that their Internet uses are homogenous. Analyzing data about the Web uses of 270 adults from across the United States, the article explores the differences in 18- to 26-year-olds' online activities and what social factors explain the variation. Findings suggest that those with higher levels of education and of a more resource-rich background use the Web for more “capitalenhancing” activities. Detailed analyses of user attributes also reveal that online skill is an important mediating factor in the types of activities people pursue online. The authors discuss the implications of these findings for a “second-level digital divide,” that is, differences among the population of young adult Internet users.
Firearm ownership is prevalent in the US and many children spend time in areas where firearms are not stored safely. The AAP recommends firearm safety counseling at pediatric well-visits.
We ...developed and tested six contextual messages to promote safe firearm storage based on: absence of harm, collective appeal to understanding child behavior, pediatrician's authority, evidence-based, fear appeal, and general safety considerations. One hundred four parents who keep firearms at home were recruited from Amazon Mechanical Turk Prime and viewed video messages and reported behavioral intentions and emotional reactions following each message.
All six contextual messages were perceived as important and believable and increased parents' intentions to follow safety advice provided, but also elicited negative emotions. The authority message elicited more negative emotions and resulted in lower intentions to follow safe storage advice.
Including firearm messages with other child safety advice merits further evaluation. Authority messages should be avoided.
Using automated content analysis, this research explores the phenomenon of pseudo-events coverage in The New York Times (N = 70,370 articles) from 1980 to 2019. By clarifying the operationalization ...of pseudo-events, this study introduces pseudo-events as a valuable tool to index how different social subsystems perpetuate mediatization (which is when institutions absorb and abide by media logic). Machine-learning classifiers were constructed to measure pseudo-events, which provides historicity, specificity, and measurability — three tasks set forth for new mediatization research. We found a significant increase in pseudo-event coverage, expressing a more positive tone than genuine event coverage. Moreover, political pseudo-event coverage shows quadrennial cycles with peaks in each presidential election year. Our findings reveal the expansion of mediatization since 1980 and show how media logic has been internalized in different ways by the social subsystems of politics, culture, and economics. Institutions and their social actors need efficient tools to abide by media logic in seeking publicity and commanding authority, and pseudo-events have matured into one of the most dominant tools, especially for political actors. This study offers an innovative approach to capture complex phenomena and shows promises of broader application of machine learning to empirically quantify and identify patterns using theoretical concepts.
•Pseudo-event coverage has increased since 1980 in The New York Times N = 70,370.•Political pseudo-event coverage peaks in each presidential election year.•Pseudo-event coverage has a more positive tone than genuine event coverage.•Charisma is more popular than rationality to gain authority in pseudo-events.

This study investigated how highly experienced environmental journalists view the professional norms of objectivity when covering climate change over time. Elite journalists were sought, and all had ...a minimum of 10 years of experience in climate coverage. In-depth interviews revealed a paradox: Most still profess belief in objectivity even as they reject or redefine it. Participants said that journalists should use objective practices and refrain from revealing their own biases, including advocating for the environment. However, participants have radically redefined the component of objectivity known as “balance.” They now advocate a “weight-of-evidence” approach, where stories reflect scientific consensus.
Stories about climate change garner passionate comments from readers, ranging from acclaim to invective. This research is the first to investigate the effects of the rhetorical strategies of ...deploying anecdotal versus scientific evidence in comments. A between-subjects experiment with a U.S. adult sample (
N
= 363) tested whether user comments that support or contradict a climate news story, using either anecdotal or scientific evidence, have an effect on message reception. Individual difference variables in audience members have been shown to moderate the effects of comments in previous research. Findings show that political ideology is an important moderator of effects, particularly on the perception of climate change risk and story credibility. And when looking at the reactions of people who have low need for cognition and are highly conservative, climate uncertainty was diminished when anecdotal evidence appeared in comments. Taken together, these findings indicate that, in the context of climate change communication, comments from users can influence whether a climate story is perceived as credible by certain readers and can also disrupt a story’s intended message, particularly if comments attempt to invoke scientific proof for their claims.
Background. Antiobesity campaigns blaming individual behaviors for obesity have sparked concern that an emphasis on individual behavior may lead to stigmatization of overweight or obese people. Past ...studies have shown that perpetuating stigma is not effective for influencing behavior. Purpose. This study examined whether stigmatizing or nonstigmatizing images and text in antiobesity advertisements led to differences in health-related behavioral intentions. Method. Participants in this experiment were 161 American adults. Measures included self-reported body mass index, weight satisfaction, antifat attitudes, and intention to increase healthy behaviors. Results. Images in particular prompted intention to increase healthy behavior, but only among participants who were not overweight or obese. Conclusion. Images and text emphasizing individual responsibility for obesity may influence behavioral intention among those who are not overweight, but they do not seem to be effective at altering behavioral intentions among overweight people, the target audience for many antiobesity messages. Images in antiobesity messages intended to alter behavior are influential and should be selected carefully.
Antiobesity health communication campaigns often target individual behavior, but these ads might inflate the role of individual responsibility at the expense of other health determinants. In a 2 × 2 ...full-factorial, randomized, online experiment, 162 American adults viewed antiobesity advertisements that varied in emphasizing social or individual causation for obesity through text and images. Locus for attribution of responsibility for obesity causes and solutions was measured, as was how these responses were moderated by political ideology. Participants who viewed text emphasizing individual responsibility were less likely to agree that genetic factors caused obesity. Conservative participants who viewed images of overweight individuals were less likely than liberal participants to agree that social factors were responsible for causing obesity. In addition, among conservative participants who viewed images of fast food versus images of overweight individuals, agreement that the food industry bore some responsibility mediated support for policy solutions to obesity. These findings, among others, demonstrate that awareness of multilevel determinants of health outcomes can be a precursor of support for policy solutions to obesity among those not politically inclined to support antiobesity policy. In addition, stigmatizing images of overweight individuals in antiobesity campaigns might overemphasize the role of individual behavior in obesity at the expense of other factors.
Guided by the elaboration likelihood model and framing theory, this study explores the potential of short-form video platforms (e.g. TikTok), for targeted clinical trial recruitment. An online ...experiment compared doctor vs. peer-led videos addressing logistical or psychological barriers to participation, mimicking common TikTok communication tactics. Results indicate that high (vs. low) TikTok users are more persuaded by recruitment messages, and they exhibit stronger intentions to participate in clinical trials. Although doctor-sourced messages generate greater credibility and a more favorable message attitude, peer-sourced messages may be more effective in increasing participation intention. Lastly, doctor-sourced videos that address logistical barriers and peer-sourced videos that discuss psychological barriers result in higher self-efficacy for clinical trial participation. This study contributes to the growing body of research on new media's role in health communication and provides insights into how to strategically utilize TikTok and other short-form video platforms for clinical trial recruitment.
This study examined whether framing, exemplar presence and exemplar race in social media news posts influence rural White men's perceptions, attitudes and behavioral intentions toward clinical trial ...participation, and if so, how individual trust in doctors moderates the effects of these three factors. An experiment with a 2 within (framing: cognitive versus psychological barriers) x 2 within (exemplar: present versus absent) x 2 between (exemplar race: White versus Black) subjects mixed factorial design was conducted among rural White men (N = 208). Twelve social media news posts about clinical trial participation were created for the experiment. Results revealed that respondents had greater behavioral intentions to participate in clinical trials after seeing posts with exemplars present (versus absent). When news posts addressed cognitive barriers (e.g. lacking knowledge about the value of clinical trials), the presence of exemplars enhanced perceived self-efficacy to participate in clinical trials. Participants with lower trust in doctors reported more favorable attitudes to posts with exemplars, and the posts with Black exemplars were perceived as more effective (approaching statistical significance). When communicating about clinical trials to rural White men, health professionals should consider including exemplars and addressing cognitive barriers to participation.
