How a Flash of Anger Lowers the Bar for Sharing Shaky News

Most explanations for why bad information spreads online lean on a comforting story about competence. People share false things, the thinking goes, because they cannot tell the difference between a reliable report and a fabricated one. Fix the knowledge gap and the problem shrinks. A set of new experiments complicates that picture in an uncomfortable way. It suggests that a rush of anger can send someone to the share button without touching their ability to judge what is actually true. The judgment stays intact. What erodes is the pause before acting.

The work comes from Haoyang Jiang, Hongbo Yu, Shenyuan Guo, and Xiaozhe Peng, whose research group at Shenzhen University studies how emotion shapes communication [1]. Their paper appeared in the journal Cognition and Emotion in 2026 [2]. Rather than rely on a single test, the team ran three experiments, each approaching the same question from a slightly different angle, which is part of what makes the pattern worth taking seriously.

In the first experiment, 223 online participants read headlines that varied in credibility and in how morally charged they were. When people had been steered toward anger, they were markedly more willing to share stories from low-credibility sources than participants who had not [1]. The second experiment, with 116 university students, pitted anger against a different negative emotion — disgust — to check whether any bad feeling would do. It would not. Anger specifically loosened the grip that source credibility normally has on the decision to share. Disgust did not produce the same effect, which matters, because it means the finding is about anger in particular rather than negative mood in general.

The third experiment is where the mechanism comes into focus. With a smaller group of 63 students, the researchers stirred anger by having people recall an infuriating memory, then applied a technique called drift-diffusion modeling to the sharing decisions. That method is a way of mathematically pulling apart a choice into its moving parts — roughly, how much evidence a person accumulates before committing, and how high they set the bar for "enough." The modeling showed that anger lowered the decision threshold [1]. Angry participants required less evidence and less time before deciding to pass a story along. The gate that normally holds a questionable headline back had simply been propped a little more open.

The most important detail is what anger did not do. It did not muddy people's grasp of accuracy. Across the experiments, angry participants could still tell true headlines from false ones about as well as anyone else [1]. So this is not a story about anger making people gullible. It is a story about anger changing the calculus of action. You can know, on some level, that a source is thin and still find that the emotional momentum carries you past the point where you would ordinarily hesitate. The knowledge is there; it just gets outvoted.

That reframing has real consequences for how we think about misinformation. If the driver were purely ignorance, the fix would be education — teach people to spot unreliable sources and the sharing slows. But if a big part of the problem is emotional acceleration, then better source-literacy alone will not be enough, because the people sharing may already recognize the source as shaky. The relevant lever becomes the moment of arousal itself: the design of feeds that reward outrage, and the personal habit of noticing when a spike of anger is doing the deciding for you. A headline engineered to make you furious is, in effect, engineered to lower your threshold.

Several caveats keep this in proportion. The experiments were controlled and modest in size, especially the third, and the anger was induced deliberately in a lab rather than arising in the wild churn of a real timeline. Emotions in daily life are messier, longer-lasting, and tangled up with everything else scrolling past. The samples were drawn largely from Chinese online users and students, so it is an open question how neatly the pattern transfers to other populations and platforms. And "willingness to share" measured in a study is a stand-in for the real thing; intending to share a headline in an experiment is not identical to broadcasting it to your actual social network, with your name attached. As with most single lines of research, this is a strong signal rather than a closed case.

Even so, the practical takeaway is unusually clean. The next time a story makes your pulse jump and your thumb hover, the useful move is not to ask whether you can tell if it is real — you probably can — but to notice that the anger is quietly lowering your standard for what deserves amplifying. A short pause is doing more work than it looks. The way our inner emotional state shapes how we treat other people and ideas is a recurring theme in this research area, including work on how being kinder to yourself connects to fairer attitudes toward others.
