Why Emotional Political Posts Online Often Trigger Skepticism, Cornell University and Cambridge University Press Find

Posting online about a political issue can bring a rush of relief, especially when you put intense feelings into words. Plenty of people share highly charged messages in the hope of shifting opinions or prompting others to act.

Evidence published by Cambridge University Press, based on research from Cornell University, points to an unexpected twist: while emotional posts can make the writer feel better, readers frequently doubt them rather than accept them at face value.

Emotions spread so easily online

Emotional reactions are now on constant display. On platforms such as TikTok, Instagram and X, it is easy to see how quickly others respond to political events.

Even traditional reporting often features emotive remarks from everyday people, which makes feelings far more prominent in public discussion than they used to be.

The researchers describe this as a relatively new environment. Previously, emotions were more commonly experienced in private; now, people broadcast them to strangers worldwide, producing a vast stream of emotional expression online.

At first glance, that visibility can seem beneficial. Watching someone cry or express fear may prompt others to care, and it can foster empathy and a sense of connection. However, those effects depend on viewers believing the emotions are genuine.

Emotional posts aren’t always convincing

It is widely assumed that strong emotion makes political communication more persuasive. The study, however, suggests the opposite often happens: readers can become more doubtful when they encounter emotional political content.

“Making people emotional is a great way to motivate them to care about an issue. But expressing your own emotions is not necessarily going to change others’ minds about that issue,” said Talbot M. Andrews, an assistant professor of government from Cornell University.

The research argues that people evaluate emotional posts along two dimensions. They consider whether the emotion seems fitting for the situation, and they also assess whether it appears authentic. If either judgement comes back negative, the message tends to lose its persuasive force.

People doubt emotions

Across multiple experiments involving thousands of participants, the researchers compared emotional and neutral posts about climate change. A consistent pattern emerged.

Emotional content was frequently rated as less sincere and less appropriate. Notably, this occurred even among people who agreed with the message itself, showing that agreement does not automatically translate into trust.

The study also outlines a reason for this reaction: audiences recognise that online material can be edited, carefully staged and even amplified. That awareness can make emotional posts feel less spontaneous, and when something appears planned, it is more likely to be seen as less genuine.

Social media makes emotions more visible

A central concept in the research is visibility. Social media enables individuals to display emotion to very large audiences, and that scale shapes how onlookers interpret what they see.

Because posts are public, they may be read as attempts to gain attention or approval. Some viewers interpret this as self-promotion rather than straightforward self-expression, which can undermine credibility.

Meanwhile, emotional posts tend to travel further online. Content that conveys intense feeling often attracts more likes, shares and comments, reinforcing a cycle in which emotional expression becomes increasingly common even as people remain wary of it.

Seeing faces can increase doubt

Visual media introduces another complication. On TikTok in particular, users may film themselves crying or reacting strongly on camera. Although that might appear more authentic, the findings suggest it can have the opposite effect.

When emotion is shown through faces and gestures, some viewers judge it as overstated. A tearful expression or dramatic reaction can seem less suitable to the context, and instead of boosting trust, it may heighten suspicion.

“We thought people might see emotions as more authentic in news articles, where journalists act as gatekeepers, compared to social media, where people have editorial control before sharing anything. Surprisingly, we didn’t find many differences.”

In other words, emotional quotations can still be questioned even when they appear in journalism.

Agreement does not remove skepticism

You might assume that if someone already supports the cause, they will accept emotional messaging more readily. The research indicates that scepticism often persists regardless.

“People are skeptical when they disagree with social media posts at all, but the effect of emotional expression is pretty similar either way. We saw the same pattern in an experiment featuring posts from a climate skeptic. People tended to see the emotion as manipulative.”

Some readers interpret emotional expression as an attempt to influence feelings rather than share them, which can reduce trust even among those who back the broader issue.

Emotional posts do not reduce concern

One nuance is important: the sceptical reaction does not appear to lessen concern about the underlying topic. In the case of climate change, for instance, people remained worried.

“[Backlash toward emotional posts] seems localized to the person who’s being emotional. It’s more that people will be skeptical of your sincerity in posting, but participants were no less worried about climate change because they saw someone get emotional about it.”

So, while the subject can still be taken seriously, the individual expressing strong emotion may be seen as less credible.

Why people still share emotions

Even if emotional posts are not especially effective at persuading opponents, they can still serve a purpose. Sharing feelings can help people find others who share their concerns and can strengthen communities built around common causes.

The research also notes a personal benefit: expressing emotion can be reassuring. It may help people work through complicated feelings and ease stress.

“Emotional expression can serve an important role, helping people find a community that cares about their issue. Even if it doesn’t achieve any influential goal – like persuading others or building social media clout – expressing emotions often makes people feel better.”

What this means for everyday life

Taken together, the findings point to a straightforward takeaway. Emotional posts can be valuable for self-expression and connection, but they are not reliably persuasive.

If someone’s goal is to change another person’s view, a measured, clear explanation may be more effective. If they are seeking support or a sense of release, sharing emotions online can still be worthwhile.

Keeping this in mind may help people use social media more thoughtfully, and it also sheds light on why emotionally intense political exchanges online so often fail to shift opinions, even when the language feels compelling.
