The Science Behind Microexpressions

You’re in a business negotiation. Your counterpart smiles and nods… but just for a split second, you catch a flash of something else — maybe surprise, fear, or even contempt.
It’s gone before you can name it. But something inside you knows: there’s more beneath the surface.
That fleeting moment? That was a microexpression — a fast, involuntary facial expression that reveals a person’s true emotion, even when they try to hide it.
In this article, we explore the science of microexpressions, why they’re essential to master in leadership and communication, and how you can learn to read — and manage — them effectively in both virtual and real-world interactions.
What Are Microexpressions?
Microexpressions are rapid facial movements that occur in less than 1/2 of a second — often as quick as 1/25th of a second. They happen automatically when someone experiences a strong emotion but tries to suppress, mask, or control their facial response.
These expressions are universal, involuntary, and rooted in evolutionary biology. Even if someone tries to put on a "poker face," their real emotions can leak through these tiny muscle movements.
First scientifically documented by psychologist Paul Ekman, microexpressions are now used in fields ranging from national security and law enforcement to therapy, business negotiation, and lie detection.
The Seven Universal Microexpressions
Research shows that humans across cultures exhibit seven universal emotions through facial expressions:
Emotion | Common Microexpression Features |
Happiness | Crow’s feet wrinkles, raised cheeks, eye crinkle (genuine smile) |
Sadness | Drooping eyelids, downturned mouth, inner eyebrows drawn up |
Anger | Eyebrows down and together, glaring eyes, lips pressed tightly |
Fear | Wide eyes, raised eyebrows, lips stretched horizontally |
Surprise | Raised eyebrows, wide-open eyes, dropped jaw |
Disgust | Nose wrinkling, upper lip raised, face turned slightly away |
Contempt | Lip corner raised on one side (smirk-like expression) |
These microexpressions can flash briefly during high-stress moments — like performance reviews, interviews, sales pitches, or tense negotiations — and give away the emotions behind the words.
Why Microexpressions Matter in Communication
✅ 1. They Reveal Hidden Emotions
People may say one thing, but feel another. Microexpressions help uncover:
Discomfort during feedback
Disagreement in meetings
Anxiety during performance evaluations
Deception or uncertainty in negotiations
Reading microexpressions helps you tune into the truth — even when it’s unspoken.
✅ 2. They Build (or Break) Trust
If you respond to what people actually feel — not just what they say — you build deeper, faster trust.
Ignoring someone's microexpression of discomfort can make them feel unseen. Acknowledging it gently shows empathy.
✅ 3. They Enhance Leadership Presence
Leaders who can detect emotional shifts quickly and subtly can better:
Adjust tone in real-time
Resolve tensions early
Navigate team dynamics with emotional intelligence
✅ 4. They Help Decode Cross-Cultural Interactions
Microexpressions are biologically hardwired and universal, even if cultural display rules vary.
In Japan, people may mask emotions — but microexpressions still surface. In the US or Brazil, emotions may be more openly shown — and confirmed by microexpressions.
Reading Microexpressions: The Key Skills
🧠 1. Train Your Eyes to Catch the Flash
Microexpressions are brief — so you need focused observation.
Practice with video simulations or live role-play. The goal is to notice quick flashes of muscle movement in:
The eyes
Eyebrows
Mouth corners
Nasolabial area (around the nose)
🎭 2. Context Is Crucial
A single expression doesn’t tell the full story. Consider:
The environment (e.g., is this a tense moment?)
The person’s baseline (how do they usually express themselves?)
Clustering cues (does body language support or contradict facial expressions?)
A smirk during a compliment may signal sarcasm, not confidence.
🤫 3. Respond, Don’t React
When you detect a microexpression:
Don’t call it out or embarrass the person
Use emotional intelligence to guide your next move
“Would you like to share a different perspective?” “I sense there might be some hesitation — feel free to let me know if anything feels off.”
Applications in Professional Settings
💼 1. In Interviews
Candidates may flash fear or doubt when answering tough questions. Microexpressions can help interviewers spot pressure points, dishonesty, or unresolved concerns.
💰 2. In Sales and Negotiations
A potential client may say “That sounds good,” while flashing disgust or doubt. A skilled negotiator can pivot and address unspoken objections before the deal slips away.
🧑🏫 3. In Teaching and Training
Teachers or facilitators can spot confusion, boredom, or anxiety early — allowing for real-time intervention.
🫱 4. In Conflict Resolution
A team member may say, “It’s fine,” while flashing contempt. Understanding these signals helps leaders address root issues rather than surface politeness.
Can Microexpressions Be Faked?
Not easily. Microexpressions are involuntary — which is what makes them so trustworthy.
Unlike practiced smiles or frowns, microexpressions reflect the authentic emotion behind the mask. They’re nearly impossible to suppress or fabricate consistently.
Caution: Don’t Become a “Lie Detector”
Microexpressions signal emotion, not intent. Fear doesn’t always mean guilt. Disgust doesn’t always mean dislike. Surprise doesn’t mean agreement.
Reading microexpressions is about increasing emotional awareness, not jumping to conclusions.
How to Improve Your Microexpression Skills
Practice with tools like the Paul Ekman Group’s METT (Micro Expression Training Tool)
Watch films on mute — try identifying emotional shifts from facial cues
Observe in meetings without speaking — just notice facial changes
Pair with verbal and body language for a full emotional read
Check your own expressions — become aware of what you’re signaling unconsciously
Final Thoughts: Leadership Is in the Details
Microexpressions remind us that the face speaks volumes — even in silence. In a world full of scripted speeches, polished emails, and rehearsed Zoom calls, the real emotion still leaks out — in milliseconds.
The best communicators aren’t the loudest or slickest — they’re the ones who see the flicker, pause with curiosity, and respond with empathy.
The science of microexpressions isn’t about control — it’s about connection.
