Paul Ekman: Biography And Contributions Of This Student Of Emotions
Paul Ekman has been a pioneer in the study of human emotions and their relationship with facial expressions, in addition to being known and noted for being among the 100 most influential psychologists of the century.
During his almost 40 years of research, Ekman discovered that there are about 10,000 facial expressions in our gestural repertoire but only a third has emotional meaning.
Paul Ekman is one of the most influential psychologists in the field of emotions and nonverbal communication. His research on facial expressions, microexpressions, and universal emotions has had a significant impact on psychology, law enforcement, and even popular culture.
Ekman’s work has helped us understand how emotions are expressed across different cultures, and how subtle facial movements can reveal hidden feelings. His studies have also contributed to the fields of deception detection, emotional intelligence, and psychotherapy.
In this article, we will explore Paul Ekman’s life, his major contributions to psychology, and how his research continues to shape our understanding of human emotions.
Paul Ekman was born on February 15, 1934, in Washington, D.C., and grew up in a family of academics. From a young age, he was fascinated by human behavior and emotions, which led him to pursue psychology.
He studied at the University of Chicago and New York University, earning his Ph.D. in clinical psychology in 1958. His early research focused on nonverbal communication, particularly gestures and facial expressions.
Early Research and Career
During the 1960s, Ekman began studying whether facial expressions were universal or culturally learned. At the time, many psychologists believed that emotions were socially constructed and varied between cultures.
However, Ekman’s research suggested otherwise. Inspired by Charles Darwin’s theory that emotions are biologically hardwired, he set out to prove that people worldwide express emotions in the same way, regardless of culture or language.
This led him to conduct groundbreaking studies on facial expressions and emotions, which would become the foundation of his most important work.
Military service
Although Ekman originally wanted to work in the field of psychotherapy, this desire changed when he was sent to the army in 1958, once he had completed his stay at the Langley Porter Neuropsychiatric Institute. He served at Fort Dix, New Jersey, as a psychologist lieutenant general.
There he got the idea that research in psychology could be a powerful tool to change training routines in the military, making them much more humane. This experience made him go from wanting to be a psychotherapist to wanting to be a researcher, with the intention that his findings would help as many people as possible.
Professional career
After completing his military service in 1960, Ekman accepted a position as a research associate, along with Leonard Krasner, at the Palo Alto Veterans Administration Hospital. There he worked with psychiatric patients, studying their verbal behavior.
It was at that time that he had the opportunity to meet the anthropologist Gregory Bateson, who was part of the staff at that same hospital. That contact would help Ekman so that, five years later, Bateson gave him films taken in Bali in the 1930s of his intercultural studies on expressions and gestures.
From 1960 to 1963, Ekman held an NIMH postdoctoral fellowship. Thanks to this, he could work at San Francisco State College, carrying out his first research as a principal investigator at only 29 years old. From the NIMH he would also receive an award again, this time in 1963, for his studies on non-verbal behavior.
The money offered by the NIMH would be renewed continuously for the next 40 years, and would be what would pay his salary until in 1972 he was able to be accepted as a professor at the University of California, San Francisco.
Motivated by his friend and professor Silvan S. Tomkins, Ekman stopped focusing on body movement and focused on facial expressions. It was from this change of object of study that would result in his most famous book, “Telling Lies”, known in Spanish with “How to detect lies” in 1985.
Paul Ekman would retire in 2004 as a professor of psychology in the department of psychiatry at the University of California. From 1960 to 2004 he continued to work at the Langley Porter Psychiatric Institute, although in a limited capacity and as a counselor on various clinical cases. After his retirement, Ekman founded the “Paul Ekman Group” and “Paul Ekman International.”
Influence and collaboration with the media
In 2001 Paul Ekman collaborated with the BBC’s John Cleese for the documentary “The Human Face.” Since his leap to the small screen as an expert voice in the expression of human emotions, Ekman would be constantly referenced in another television series, “Lie to Me,” whose protagonist, Dr. Lightman, is inspired by Ekman. In fact, Ekman himself served as a scientific advisor for the series, even giving the actors instructions on how to imitate facial expressions.
Although he was already retired, Ekman did not miss the opportunity to collaborate with the Pixar film “Inside Out”, also known in the Hispanic world as “Del Reverso”, from 2015. In fact, Ekman even wrote a guide to make it The film served as a guide for parents when talking about emotions with their children.
What should be clear about the figure of Ekman is that, whether due to his research, the 15 books he has written or having collaborated on the projects we have just observed, this psychologist is considered a great reference. In fact, he was among the 100 most influential people in the May 2009 issue of Time magazine. He also occupies position number 50 on the list of the most influential psychologists of the 21st century, according to the Archives of Scientific Psychology magazine in 2014.
Paul Ekman’s Contributions to Psychology
1. The Universality of Facial Expressions
One of Ekman’s most significant contributions was proving that facial expressions of emotions are universal.
To test this, he conducted studies in the 1960s and 1970s, traveling to remote, isolated tribes in Papua New Guinea. He showed them photographs of people expressing different emotions and asked them to match the images with emotional stories.
His findings demonstrated that people across all cultures recognize the same basic facial expressions, even if they had never been exposed to Western society.
Ekman identified seven basic emotions that have universal facial expressions:
This discovery challenged previous psychological theories and provided strong evidence that emotions are biologically programmed, not just learned behaviors.
2. The Facial Action Coding System (FACS)
Ekman developed the Facial Action Coding System (FACS), a scientific tool used to analyze facial movements.
🔹 FACS breaks down facial expressions into individual muscle movements called “action units”. 🔹 It allows researchers, psychologists, and law enforcement agencies to detect hidden emotions, including those people try to suppress. 🔹 It has been widely used in forensic psychology, security screening, and even artificial intelligence.
FACS remains one of the most widely used systems for studying nonverbal communication and emotional expression.
3. Microexpressions and Lie Detection
One of Ekman’s most famous discoveries is microexpressions—brief, involuntary facial expressions that reveal true emotions.
🕵️♂️ Microexpressions last only a fraction of a second and are almost impossible to control. 💡 They occur when a person tries to hide or suppress an emotion, making them useful for lie detection.
Ekman’s research on deception detection has been applied in:
✔️ Law enforcement and criminal investigations ✔️ Airport security screenings ✔️ Psychotherapy and counseling ✔️ Business and negotiation strategies
His work even influenced the popular TV series “Lie to Me”, in which the main character is based on Ekman himself.
4. Emotions and Evolutionary Psychology
Ekman’s research supports Charles Darwin’s theory that emotions are evolutionary adaptations.
🔹 Facial expressions serve as a survival mechanism, helping humans communicate danger, pleasure, or distress. 🔹 They allow us to understand others’ emotions even before they speak. 🔹 Ekman’s studies have shown that even blind people display the same facial expressions as sighted individuals, proving that expressions are not learned but innate.
5. Application in Artificial Intelligence and Technology
Today, Ekman’s research is being used to develop emotion recognition software.
🔹 AI systems now analyze facial expressions in customer service, security, and social media interactions. 🔹 His work has contributed to the creation of virtual assistants that can recognize human emotions.
The combination of psychology and technology continues to evolve, and Ekman’s theories remain at the forefront of this innovation.
Criticism and Controversy
Despite his contributions, Ekman’s work has faced some criticism:
🔸 Microexpressions and Lie Detection Accuracy: Some experts argue that detecting lies based on facial expressions alone is unreliable and should not be used as the sole indicator of deception. 🔸 Cultural Differences in Emotional Display: While facial expressions are universal, the way people display and interpret emotions can vary across cultures.
Even with these critiques, Ekman’s research remains a cornerstone of modern psychology, influencing therapy, law enforcement, and artificial intelligence.
Paul Ekman’s work has revolutionized our understanding of emotions and facial expressions. His research on universal emotions, microexpressions, and deception detection has left a lasting impact on psychology, law enforcement, and technology.
Although some of his theories remain controversial, Ekman’s contributions have helped bridge the gap between psychology and real-world applications, making him one of the most influential psychologists of our time.
