Are you passing along something true or false? Dissemination of social media messages about genetically modified organisms

Does China have a public debate on genetically modified organisms? A discourse network analysis of public debate on Weibo

We examine stakeholder participation in the online debate on genetically modified organisms in China and assess how the debate has changed over time. Therefore, we compare messages posted between 2013 and 2020 on the Chinese microblog website Weibo by using discourse network analysis. Our findings reveal strong opposition to genetically modified crops, along with the existence of two competing coalitions of supporters and opponents. We further observe an increasing number of posts supporting genetically modified organisms by the public in recent years. Consequently, there is an indication that the positions of stakeholders have changed over time. We discuss the policy implications for China and draw conclusions for other countries.

Co-design of a Teaching-Learning Sequence to Address COVID‑19 as a Socio‑scientific Issue in an Infodemic Context

In the post-truth era, one challenge facing science education is the circulation of fake news that distorts the information available for decision-making on issues that have a scientific basis and are controversial for society. In this work, we aimed at designing a learning environment with the objective of equipping students with skills that allow them to deal with socio-scientific issues (SSI) in an infodemic context. To this end, we proposed an educational innovation through design-based research, which was oriented to the treatment of information disseminated in the media and social networks related to COVID-19. We divided this information into four major constructs: virus and disease dynamics; pandemic and environmental crisis; hygiene and protocols; and vaccines, potential solutions, and pharmaceutical industry. On the basis of the activities of the didactic sequence, which included class discussion, interviews with the immediate environment, audiovisual productions, and a final plenary, we identified criteria that students applied to trust or not trust the circulating information and a series of strategies to corroborate the information. In addition, framing COVID-19 as an SSI allowed the discussion of curricular content in science and on sociocultural dimensions that cross the pandemic. Based on the implementation of the teaching-learning sequence, we conclude that the proposed activities favored reflection on critical thinking and awareness of the responsibilities they have as potential disseminators and/or generators of information.

Facilitating Scientific Communication Between Strangers: A Preregistered Lost E-Mail Experiment

Communication scholars are increasingly concerned about biases that shape people's interactions with science. Past study has focused on echo chambers (cultivating social networks that reinforce existing worldviews). People's facilitation of scientific discourse between strangers also may be shaped by their attitudes. To study the latter, we employed a recent adaptation of Milgram's lost letter technique called the lost e-mail technique (LET). We conducted a preregistered field study using a large undergraduate university sample (N = 1,508) to examine how the LET might elucidate people's treatment of scientific information. We distributed four ostensibly misaddressed scientific messages and monitored the likelihood of these e-mails being facilitated by participants. Participants' beliefs about self-esteem's importance, assessed months earlier, were associated with increased facilitation of scientific claims congruent with (vs. incongruent with) these beliefs. Thus, people shape the spread of online information in a manner matching their beliefs, even for people outside their social networks.

The Public Discussion on Flat Earth Movement: An Analysis Based on the Esperantist‑Epideictic Discourse

The paper reflects on public discourses about science and pseudoscience, proposing the same discursive structure for both-the Esperantist-Epideictic genre. This genre of discourse might bring together characteristics that we understand as constituents of the public discourse on science. It also enables us to depict the process by which to maintain cohesion on a group's values. The discursive activity points to science as neutral, free, and independent of social influences captivating those already in this discursive sphere. The discursive hermeticity appears in the Esperantist content and the Epideictic form by avoiding the dialogical situations where there is no epistemological and axiological dispute. We thus, show that the Esperantist-Epideictic genre helps to understand the process of maintaining a cohesive group whose beliefs about the Flat Earth appear in social media. We use data from three sources: transcriptions from seminars held at that 1st FlatCon Brazil, most viewed videos on YouTube where affirmationists talk about Flat Earth, and semi-structured exploratory interviews conducted at FlatCon. Our findings indicate that some conceptions of validation of knowledge, scientific method, science bias, reality, and truth compound a distinct part in the current conversations about the Flat Earth movement. Moreover, the Esperantist-Epideictic genre of discourse can be an analytical tool for framing the echo chamber in social media while defending or attacking the Flat Earth movement. We conclude that in a time where there is a growing consensus that science is under attack, the ways in which its defenders are trying to stand up to it may be causing some harm.

What do we believe in? Rumors and processing strategies during the COVID-19 outbreak in China

The COVID-19 pandemic is called the first infodemic in history. Those first confronted by the enormous challenge of fighting this infodemic to save their lives were the people of Hubei Province in China. To understand how they defined and processed rumors, we conducted an interview study with Hubei residents when they were under lockdown. We found that they typically defined rumors in terms of one or two of three features: non-factual information, information unsanctioned by the government, and information causing panic. They reported low motivation in verifying the information and often either rejected any information they perceived as suspicious or waited for the government to debunk rumors. Even among those who tried to verify information, most relied exclusively on heuristic processing cues such as source credibility, linguistic and visual cues, and intuition. Systematic processing strategies such as fact-checking and discussing with family and friends were seldom used.
