Chapter 2 Section 1 How the FBI Insights into Micro-Reactions of Facial Expressions

The researchers of the FBI Institute of Non-verbal Information Science have come to such a conclusion through testing and research: the distribution of human facial muscles is very concentrated, and these muscles can continuously transmit signals to the central nervous system of the brain. In the process of transmitting signals, There will be thousands of different expressions, including crying, smiling, excited, disappointed, melancholy, etc.In the process of transmitting signals, everyone's facial expressions will be different, but the expressions they transmit are used as auxiliary clues to solve the case, which is very helpful for the police officers to analyze the case in depth.

Bright, a researcher at the FBI's Institute of Non-Verbal Information Science, also pointed out that although facial information can reflect changes in some people's expressions and inner world, sometimes people can consciously control facial expressions to make it true to their inner world. Thoughts make a difference. Brett, a researcher at the FBI's Institute of Nonverbal Information Science, explained through vivid cases: Everyone has such an experience, that is, when we are studying in school, the teacher often teaches us to be a good student and not to be playful. I am very tired from studying, so I have to pretend that I don't care, and I have to pretend to be eager to learn in front of my classmates.It is under this kind of education that some people begin to lie unconsciously at a very young age. If this kind of thinking has been accompanied by children's growth, then they will continue to lie.Therefore, although facial expressions can provide a variety of meaningful non-verbal information that allows us to understand the thoughts and feelings of others, we must bear in mind that there are certain deviations in these information, and we need to make serious judgments from reality.

Lewis is a researcher specializing in human facial expressions at the FBI Institute of Non-verbal Information Science. Through years of research and practice, from a psychological point of view, he has summed up a set of timely and accurate analysis of human facial features. In order to help the police uncover the mystery behind the case step by step.Lewis believes that many people will have negative expressions in the face of adversity, such as blushing, red nose, tight lips, etc. Through further observation of them, it can be found that their demeanor becomes more abnormal, and their eyes will stagnate in one place. And the neck is also stiff, and I can't look around.These situations will occur briefly, which requires FBI officers to read some non-verbal information from these brief processes.Many suspects often hide their crimes deeply in their hearts and are unwilling to cooperate with the FBI's interrogation work.If we don't observe carefully, we will not be able to discover their true inner thoughts.For example, in the process of playing bridge with friends, even if the cards in their hands are very good, people will pretend to be calm, instead of showing complacent expressions, they will be more low-key and conservative.They believe that the opponent should not be able to see the quality of the cards from their own expressions. Only in this way can they effectively confuse the opponent and give themselves an advantage.When people feel comfortable and relaxed physically and mentally, their facial muscles will be completely relaxed. This relaxed state is not deliberately pretended, it is the most natural way of expressing comfort and relaxation.For example, this visceral relaxation may not occur when sharing a car with someone they don't know in an unfamiliar location because they perceive unfamiliar locations and people as unreliable , can not bring them a sense of security and comfort, so they will never make a relaxed expression.

In order to be able to master the method summarized by Lewis proficiently, FBI officers often go to prisons, markets, casinos, shopping malls and other places to practice the skills of capturing facial expressions. FBI officers used this method to successfully detect many espionage cases that affected the security of the United States in the 20th century.Therefore, we can also use these methods to capture non-verbal information in our life and work, so as to understand the true thoughts of the other party. People's facial expressions can reflect some information, and we can gain insight into each other's inner world from facial expressions, which will bring a lot of convenience to our work and social interaction.
