When science speaks in extremes: Study proposes system for detecting polarized discourse

A study in the Journal of Science Communication elucidated, based on available scientific literature, the characteristics of polarized scientific digital messages, proposing a system of codification for identifying and characterizing polarized discourses in science communication digital messages.
"Polarized messages in online science communication often present extreme views about a specific scientific topic, which can stir strong emotions, reinforce group loyalty, and deepen divisions in society," explains Thiago Cruvinel, professor at the University of São Paulo, Brazil, and coordinator of the research.
"These polarized views can affect various social aspects. For example, to make people feel certain and comfortable, a one-sided message might use terms related to conflict or separation, even when talking about well-known scientific topics like climate change caused by humans."
As Cruvinel explains, simplifying and polarizing scientific information is not always the best approach, as it can limit critical thinking. Presenting scientific agreement as unquestionable may unite supporters but push away skeptics, making the issue even more divisive.
When one dominant view takes over, it can hold back scientific progress by discouraging people from challenging existing ideas, which is a key part of advancing science.
Cruvinel and his colleagues' work mapped the scientific literature that examined the syntactic and lexical features of polarized messages in online science communication, as well as studies measuring the effects of these messages on readers' opinions, which also involved more specialized audiences like journalists, scientists, and health professionals.
This scoping review mapped the available literature, identifying ten studies that allowed Cruvinel and his colleagues to develop a system to identify polarized scientific messages.
"Our codification system is grounded in a framework that encompasses 20 distinct codes, categorized into four key dimensions: sideness, criticism, emphasis, and discordance," explains Cruvinel. "This structured approach enables a nuanced analysis of the underlying elements contributing to polarization within scientific discourse."
According to Cruvinel, an important contribution of this study is that this coding system can serve as a valuable tool for science researchers and journalists, supporting the systematic identification of polarized materials within the realm of science communication.
