Emotions and group dynamics around misinformation on social media

Nuanced views and clean facts don’t generate clicks. Social networks are designed to speak to our emotions; the more extreme the emotions, the better the content. But that does not mean that good arguments, education, and science communication are futile.

Emotions attract our attention, and provide us with information about actions we should take: When you feel fear, it’s best not to ignore the danger, and protect yourself from it. When you are angry, it’s probably because someone has treated you or a group you belong to unfairly, and it’s time to step up against the injustice.

News agencies, politicians, and creators of fake news know this, and use it to create content that attracts attention and is likely to be shared on digital and social media. Algorithms on social media are optimized to increase engagement with content (Narayanan, 2023; Metzler & Garcia, 2023), and content that provokes strong emotional reactions is a powerful means to do so. Negative moral-emotional messages about groups we do not like seem to particularly increase engagement (Brady et al., 2017, Rathje et al. 2021, Antoine et al., 2023). Humans are social animals, and things that make us feel part of a group, that increase our group’s status, or decrease the status of an out-group, are highly motivating for us (Robertson et al., 2022).

We can regularly observe such emotional group dynamics around the topic of climate change on social media. On the one hand, there are people who think we are not doing enough and need to urgently take action: social movements like Fridays for Future or Extinction Rebellion, and political parties like the Green parties in Europe, or Democrats in the US. On the other side, climate scepticism and denial are more common in far-right, populist or libertarian parties, who oppose economic regulation and benefit from using anti-elite rhetoric (Lewandowsky, 2021). Polarized conversations between these different sides on social media grow around events like climate protests, or releases of climate change reports, such as the reports from the Intergovernmental Panel on Climate Change, (Sanford, 2021). And political polarization fuels the spread of misinformation (Osmundsen et al., 2021, Antoine et al., 2023).

Because more outrageous content attracts more attention, and individuals with stronger opinions are more motivated to persuade others, extreme voices and toxic content are more visible on social media (Bail, 2021). Individuals with more nuanced views, who can relate to both sides of a debate, are much less visible. A large majority of individuals who are not interested enough to participate in discussions, but generally agree with a nuanced perspective, is entirely invisible. This way, digital media make polarization seem stronger than it actually is in society, and this in turn fuels hate and misunderstanding between parties (Brady et al. 2023). Redesigning platforms so that nuanced majorities and overlap in the views of different groups become more visible, could therefore help to decrease the spreading of misinformation (Metzler & Garcia, 2023). Redesigning social media algorithms could be one way to do so.

Fortunately, people do not uncritically believe any emotional information that comes their way (Mercier, 2020). Key questions such as who shares news, whether they know and trust the source, and if it fits with what they already know and believe about the world, crucially determine if we find information plausible. People's anger after reading false news, for example, can occur because they recognize it as misinformation and disagree (Lühring et al., 2023). So, strong emotions do not automatically mean people will believe a message and continue to share it. That people judge new information based on trust in sources, and their knowledge about the world, means that good arguments, education, and science communication are not futile. Explaining how we know climate change is happening, how it works, how solutions can integrate economic and environmental needs, for example, takes time and effort. But it will also help to increase trust in science, and politics that implements such evidence-based solutions, and thereby decrease polarization and misinformation.
