In a world dominated by social media, emotional posts may feel like the most natural way to communicate. We post outrage, sadness, empathy, and passion—often believing these signals will persuade others to see what we see and feel what we feel.
But new research entitled “Emotions on our Screens” suggests something surprising: emotional expression may actually reduce persuasive impact, even when audiences agree with the message.
This insight has profound implications—not just for digital communication, but for how we understand nonverbal behavior, facial expressions of emotion, and credibility in human interaction.
Emotional Expression vs. Persuasion: A Disconnect
The study found that when people encounter emotional content online—especially expressions of sadness or distress—they often respond with skepticism rather than empathy.
Participants across multiple experiments:
- Rated emotional posts as less authentic
- Viewed emotional expressions as less appropriate
- Were more likely to interpret emotional displays as manipulative
Even more striking: this reaction held regardless of political agreement. In other words, even when people agreed with the message, the emotional delivery reduced trust in the communicator.
This creates a paradox:
Emotion increases visibility and engagement—but decreases credibility and persuasion.
The Role of Nonverbal Behavior in Digital Contexts
From a Humintell perspective, this research aligns closely with what we know about nonverbal communication.
In face-to-face interaction, nonverbal cues—tone, posture, gestures, and especially facial expressions of emotion—provide critical context that helps others interpret sincerity.
The shift to digital communication has undoubtedly changed the way we read people.
Dr. Matsumoto suggests that this largely stems from the fact that humans did not evolve to do 2-dimensional communication, such as through a computer screen. On the contrary, we have evolved our perceptual senses to live in a 3-dimensional world and our sense of reality is grounded in that fact.
Interactions are based on being live and in person. Being live and in person with somebody and interacting with them is what we’ve evolved to do and what we’ve learned to do all of our lives.
But online, those cues are:
- Reduced (text-only posts)
- Exaggerated (dramatic videos, crying selfies)
- Or ambiguous (filtered, curated expressions)
Without full nonverbal context, audiences rely on rapid judgments:
- “Is this genuine?”
- “Is this performative?”
- “Is this trying to influence me?”
When emotional signals feel misaligned or overly intense, they trigger what we might call a nonverbal credibility gap.
Facial Expressions of Emotion: When Signals Backfire
One of the most compelling findings: posts featuring a visible sad facial expression (e.g., crying) were seen as especially inappropriate and less credible.
This is fascinating from a behavioral science standpoint.
Facial expressions are typically:
- Automatic signals of internal emotional states
- Interpreted as honest indicators of feeling
However, in digital environments:
- Expressions can be staged or repeated
- Viewers assume intentional signaling rather than spontaneous emotion
This shifts perception from:
- “They feel this” → to → “They want me to feel something”
That shift is critical. It transforms emotion from a signal of authenticity into a signal of persuasion attempt.
Why Emotion Triggers Skepticism
This phenomenon connects to a well-known concept in persuasion science: the Elaboration Likelihood Model.
When people detect persuasion attempts—especially emotional ones—they often:
- Shift into more critical, analytical processing
- Question the motives behind the message
- Resist being influenced
Additionally, excessive emotional appeals can resemble what’s known as an “appeal to emotion”, where feelings are used to sway judgment rather than evidence.
In modern digital environments, audiences are highly attuned to this.
The result:
- Emotional intensity → signals persuasion intent
- Perceived persuasion intent → triggers skepticism
- Skepticism → reduces influence
Emotion Still Matters—Just Not How You Think
Importantly, the research does not suggest that emotion is useless.
In fact, emotional expression:
- Helps people build community
- Reinforces shared identity
- Provides psychological relief (catharsis)
So emotion is highly effective for:
- Connection
- Belonging
- Engagement
But less effective for:
- Changing minds
- Increasing credibility
- Persuading skeptics
Practical Implications for Communicators
If your goal is persuasion rather than expression:
- Use emotion sparingly and strategically
- Avoid exaggerated or performative facial expressions
- Pair emotional content with clear, evidence-based messaging
- Focus on credibility cues (consistency, calm delivery, clarity)
If your goal is connection:
- Emotional expression can be powerful—but expect resonance, not persuasion
Final Thought
In a digital world saturated with emotional content, audiences are becoming more sophisticated interpreters of nonverbal behavior and emotional signaling.
The irony is clear:
The more we try to persuade through emotion, the more people question our sincerity.
Understanding how facial expressions of emotion, nonverbal cues, and perceived intent interact is no longer optional—it’s essential for anyone hoping to communicate effectively in the modern age.
Ready to Influence More Effectively?
Emotional expression alone won’t persuade—and as this research shows, it can even undermine credibility.
