Study Reveals Moral Anger Significantly Accelerates Misinformation Sharing Online

Feeling morally angry makes people more likely to rapidly share misinformation online, according to new research published in the journal Cognition and Emotion. The study found that anger causes individuals to act impulsively and pay less attention to news source credibility, potentially explaining how false information spreads so quickly through social media platforms.

The research, led by Xiaozhe Peng, associate professor at the School of Psychology at Shenzhen University in China, investigated how specific emotions within moral outrage contribute to the sharing of false news. While previous research has treated moral outrage as a single emotion, this study distinguished between different components, particularly anger and disgust.

“As the lead researcher of the Emotion and Communication Neuroscience Lab, I have long been interested in how emotions shape communication,” explained Peng. “This project was motivated in part by repeatedly seeing how emotionally provocative content on social media can accelerate the spread of misinformation and sometimes even escalate into online aggression.”

The research team conducted three experiments to examine how different emotional states influence sharing decisions. In the first experiment, 223 Chinese participants viewed false news headlines depicting varying degrees of moral violations. Headlines were randomly assigned different credibility ratings, and participants were prompted to focus on either accuracy, morality, or nothing specific before indicating their willingness to share.

Results showed participants were generally more willing to share news from credible sources and stories containing severe moral violations. When prompted to focus on either accuracy or morality, participants relied less on source credibility when making sharing decisions.

The second experiment specifically compared moral anger and disgust among 116 university students. Participants read false headlines with varying credibility ratings while being prompted to feel anger, disgust, or neutral emotions. The findings revealed that anger significantly increased willingness to share headlines from low-credibility sources, while disgust had no such effect compared to the control group.

“What surprised us most was how consistently moral anger, rather than moral disgust, drove sharing across studies,” Peng noted. This aligns with existing psychological theories suggesting anger motivates confrontational behavior, whereas disgust prompts avoidance.

In the third experiment, researchers used mathematical models to analyze the cognitive processes behind sharing decisions. Sixty-three university students evaluated headlines after recalling personal memories that made them angry. The models revealed that anger lowered participants’ decision thresholds, causing them to make faster, less cautious sharing decisions.

Importantly, anger did not impair the ability to distinguish between true and false information—it simply reduced the mental barrier required before sharing content. This suggests that misinformation spreads not necessarily because people can’t recognize false content, but because anger changes how they process and act on that information.

The researchers acknowledge several limitations to their study. All experiments were conducted in controlled settings rather than on live social media platforms, and the sample was limited to Chinese participants, which may affect how broadly the findings apply across cultures and platforms where emotional expression varies.

For everyday social media users, the research offers practical guidance. “If a post makes you instantly angry, that is exactly the moment to pause before liking, commenting, or sharing,” Peng advised.

The research team is now exploring interventions that could reduce misinformation sharing without disrupting user engagement on social platforms. These include developing warnings for emotionally arousing content and addressing the emotional and decisional processes that drive sharing behavior.

“One broader message of this study is that misinformation is not only a problem of false belief; it is also a problem of emotionally charged communication,” Peng concluded. “Moral anger seems especially powerful because it is action-oriented: it pushes people toward expression, condemnation, and rapid dissemination.”

The findings could have significant implications for how social media platforms design their interfaces and how media literacy programs approach misinformation prevention, suggesting that emotional regulation might be as important as fact-checking in combating the spread of false information online.
