The most powerful communication language: body language

Do people's true feelings really show on their faces? Civilized humans have become quite adept at hiding facial expressions. This is why the FBI focuses more on leg movements than facial expressions when uncovering the truth.
Our legs are the part of our body that can't hide our emotions the most.

Good relationships can be built through efforts to read each other's minds and prevent emotional conflicts in advance.
If a woman keeps fiddling with the pendant near her neck on a blind date, it's a sign that she's uncomfortable or doesn't like the other person.
Touching or stroking the neck is a common behavior in stressful situations.

It will help the other person see you as authoritative and confident.

A book containing the FBI's original techniques for penetrating human psychology.

Recently, violent crimes have become more sophisticated and the criminals' poker faces have become more skillful, but the investigative nets of profilers pursuing them are also becoming more solid and detailed.
What's the secret to psychological investigation, finding the key to solving a criminal case that's been mired in a maze? The answer lies in behavior and facial expressions. Regardless of race, culture, or language, humans express emotions like anger, fear, joy, and pleasure through facial and bodily movements.
"The Psychology of FBI Behavior" is a book written by former FBI agent and behavioral expert Joe Navarro that contains techniques for effective communication by reading other people's body language and facial expressions to understand their minds.
The author, who became a topic of conversation in the United States by analyzing the speeches of Barack Obama and Hillary Clinton during the Democratic primary, uncovered the truth hidden in poker faces while dealing with highly trained spies and intelligent criminals at the FBI for 25 years.
Drawing on research in psychology, biology, sociology, and communication with psychologist and co-author Dr. Marvin Collins, this book analyzes the meaning of gestures and the mechanisms of behavior. It will help you increase your nonverbal communication intelligence and read others' minds.
It contains essential life skills such as negotiation, meetings, dating, and interviews, as well as advanced knowledge that is beneficial to frontline police officers investigating crimes.

Gestures are also strategies

This book goes beyond simply informing us of the characteristics of behavior.
By comprehensively analyzing the mechanisms and psychology of the human body, it provides methods to eliminate unnecessary misunderstandings and communicate effectively.


Let your body speak strategically too.
It will be a great help in achieving your goals in persuasion and negotiation.
John F.
Kennedy was often seen with his hands in his coat pockets, his thumbs sticking out, an instinctive expression of high confidence and status.
Historically, successful speakers have used hand movements appropriately.
This book says that lawyers' credibility increases when they make statements with their hands in the shape of a spire.
This is a useful gesture to reinforce your point in a presentation, interview, or speech. Don't hide your hands under the table when you're trying to convey your sincerity.
There are also experimental results that show that hiding your hands while speaking is perceived negatively as hiding your true feelings or lying.
The author emphasizes that the more active the hand expression, the higher the quality of information transmission.
In Korea, as well as in the United States, no one likes to point at others with their finger.
It is better to point with your palm facing up rather than with your fingers.
It is an expression of eliminating misunderstandings and respecting the other person.

Limbic mechanisms that expose lies

Even if your face is skillfully lying, your limbic system dictates a different biological response.
In our brain, the limbic system is the brain responsible for survival and cannot lie.
The '3F' response - freeze, flight, fight - is an instinctive response of the limbic system to ensure survival and respond to threats.
In fact, during the 1999 Columbine High School shooting and the 2007 Virginia Tech shooting, some students were able to save their lives by instinctively freezing (playing dead). The pallor of the face in difficult or dangerous situations is also a limbic system response.
The limbic system sends blood to the muscles of the arms and legs in preparation for escape when faced with a dangerous situation.
Then the face turns pale.
As blood flows from the skin to the deeper muscles, the body also becomes cold, which is why you shiver or feel chills in unfamiliar places.

The truth is revealed in the legs, not the face.

No matter how perfect a poker face a professional gambler displays, it's difficult to hide their true feelings behind the table.
When you are suspicious of your opponent, focus on the movement of their legs rather than their eyes.
The author reveals that the most honest parts of the human body are the feet and legs.
A fundamental principle of FBI psychological investigations is that the truth is revealed from top to bottom, from head to toe. Crossing one's legs is a sign of comfort.
This is because crossing your legs causes you to lose your balance, making it difficult to quickly escape when real danger arises.
You can't display this behavior unless you feel very comfortable. Learning to properly read and utilize this silent language allows you to communicate in a much more effective and nuanced way.
Make your own the FBI profiler's original technique that penetrates human psychology.
You will gain a powerful weapon to turn the situation in your favor without the other person knowing.
The body's responses are incredibly honest and are the most powerful language for communicating human intentions.
