Explore Dr. Paul Ekman's research on universal facial expressions and microexpressions revealing hidden emotions and lies.
Key Takeaways
- Facial expressions for basic emotions are universal across all human cultures.
- Microexpressions provide critical clues to hidden or concealed emotions.
- Most people cannot completely control their facial expressions, making deception detectable.
- Facial expressions are involuntary and rooted in brain areas beyond conscious control.
- Training can improve the ability to detect subtle emotional signals and lies.
What the video covers
- Facial expressions of basic emotions like happiness, anger, and surprise are universal across cultures.
- Dr. Paul Ekman conducted research in Papua New Guinea to scientifically prove universality of facial expressions.
- Even isolated tribesmen recognized facial expressions linked to specific emotions and stories.
- Each emotion has distinct facial muscle signals that are loud and recognizable without training.
- Microexpressions are brief, involuntary facial movements that can reveal concealed emotions.
- About 95% of people cannot fully inhibit their facial expressions, leading to detectable leaks.
- Microexpressions are controlled by the involuntary nervous system, similar to reflexes like blinking.
- Ekman’s research also focuses on detecting lies through subtle facial cues and microexpressions.
- Understanding involuntary facial expressions is key to connecting emotions and outward signals.
- Perseverance and curiosity are encouraged for those interested in studying facial expressions further.

Speaker A
They noticed something unusual about the expression of emotion. The face a foreign person made to show "happiness," "anger," or "surprise" was exactly the same face people made back in their home country!
Speaker A
The scientists began to wonder, "Do all people across cultures share the same, universal facial expressions for emotion?" Dr. Paul Ekman, a world-renowned psychologist, set out to answer this question.
Speaker A
And from his decades of research, we have come to understand the true complexity of human emotions.
Speaker A
The big question in going to New Guinea was not, am I going to find out whether they're universal, I already knew they’re universal, is can I get scientific evidence.
Speaker A
As a young scientist, Dr. Ekman traveled to the remote highlands of Papua New Guinea to study the four tribesmen.
Speaker A
To prove his theory, he had to show that even these people, who had never met other cultures, shared the same universal facial expressions for emotion.
Speaker A
I collected stories, and the stories were just what I would have expected. When I showed them the "sad" face, the most common story was that the child had died.
Speaker A
And I showed them an "angry" face, the most common story was they were fighting or about to fight.
Speaker A
When the four tribesmen looked at these pictures, they were actually examining the muscles of the face.
Speaker A
Searching for clues in the position of the eyes, mouth, or nose that would reveal to them how that person was feeling.
Speaker A
A sad face showing slightly closed eyes. An angry face showing pinched eyebrows. Each emotion has its own unique signal or facial expression clue.
Speaker A
The signal is quite loud. They are not subtle signals. You don't have to teach anybody how to recognize those seven emotions.
Speaker A
We teach people how to recognize when someone's trying to conceal them, which is not too easy to do.
Speaker A
Dr. Ekman is also an expert on the science of lying. His research investigates the facial movements involved in hidden emotions.
Speaker A
And creates techniques for detecting when people are hiding the truth. The facial expressions of emotion are involuntary.
Speaker A
And they come from an area of the brain that you don't have voluntary control over.
Speaker A
Some people are able to acquire the ability to, at least partially, inhibit. We found about five percent of a normal population can completely inhibit any expression.
Speaker A
Ninety-five percent can't. Ninety-five percent will... there'll be some kind of leakage, you'll see it in some muscles moving or you'll see what we call a "micro facial expression," a very brief, about a twenty-fifth of a second.
Speaker A
But most people will miss, unless you've been trained to see them. But you can learn to see them.
Speaker A
When people lie, some part of the emotional signal, a small clue from a raised lip or a quick look of the eyes, leaks out.
Speaker A
This is because micro expressions, like breathing, blinking, and yawning, are controlled by our involuntary nervous system.
Speaker A
When we feel pain... "Ouch!" the muscles of our face move automatically. And, like a reflex, we cannot control this reaction.
Speaker A
Discovering this fact was key to understanding how facial expressions and felt emotions are connected.
Speaker A
Almost, with one exception, all of my discoveries that have had import were the result of accident!
Speaker A
I can't take credit for the idea, but when an opportunity fell into my lap, I persevered like mad.
Speaker A
And I aimed as high as I could see and a little higher. Interested in examining facial expressions and making your own discoveries?
