The principal had to speak at the top of his voice, but fortunately educators like them also need to have some knowledge related to psychology, and he happened to have read some related articles: "I can understand everyone's feelings, but this micro-expression polygraph is not necessarily accurate!" Micro-expression polygraphs have been adapted from film and television dramas to be too magical, and I have also paid attention to these aspects, please listen to me calmly. ”

The restless parents quieted down one after another, all of them watching the principal, waiting for his explanation.

The principal saw that everyone was quiet, and continued in a hoarse voice: "Some scientists have found through repeated studies that even trained police officers and officers are mostly just trying to judge whether an individual is lying from body language and facial expressions. There is even a data that shows that only 50 of the 20,000 people who have participated in the micro-expression test can make an accuracy rate of more than 80%, which is not as good as judging by the method of coin toss. ”

The parents looked at each other, still skeptical.

Although Chu Rusi was refuted, he was relatively calm, because ...... There are studies that do show that.

Most of the time the lying micro-expressions are due to nervousness, so the principal can justify it, and the instructor may be a little nervous in front of many parents.

The principal looked at Chu Rusi, as the head of a school, he had also experienced it. After a lot of wind and rain, it is more than enough to deal with the small scene in front of him: "This gentleman's observation ability is really different from ordinary people, I admire it very much." ”

Chu Rusi raised his eyebrows, revealing a hint of contempt - this principal's ability is not bad, he is still very calm, and he is very upright, his breadth of knowledge is also good, and he can talk a little bit about psychology and behavior. However, if the principal tries to wrongfully accuse the students, then he is not a qualified educator.

The headmaster could feel Chu Rusi's contempt, but he also had to do it: "But I have one thing to tell this gentleman, that micro-expression polygraphs have probably been sought after by many people in the past few years. However, the more studies psychologists conduct, the more elusive the seemingly micro-expression lie detector becomes. ”

"Huh?" Chu Rusi didn't open his mouth to refute, he really wanted to hear what the principal had to say.

The principal's gaze shifted from Chu Rusi to each parent, and the majesty of a high-ranking scholar emerged spontaneously, as the head of a school, his academic research ability is definitely not weak, and he pretends to be serious and bluffs: "Because human expressions are too complicated and rich." Maybe you're familiar enough with someone that you may notice that every time he tells the truth, he twitches a little, but others may behave very differently when they tell the truth, so there is no uniform rule for body language. ”

The principal paused, as if to teach, for everyone to absorb: "There is no real sign that someone is lying, and some people giggle nervously when they lie; Others become more serious; Some people make eye contact; Others avoid eye contact. ”

Finally, when he was about to conclude, the headmaster's gaze turned around and returned to Chu Rusi: "Everyone is different, and it is obvious that there is no reliable evidence that can really distinguish between truth and lie. Even if your subconscious mind tells you which signs the other person is lying, the results are often inaccurate. ”

Xu Yinuo glanced at the principal expressionlessly, this old guy is very good at spending a lot of money, it is a big fool, and in a few words, he negated the conclusion that Chu Rusi came out.

Chu Rusi is not in a hurry at all, this kind of thing is justified by the public, and his mother-in-law says that his mother-in-law is reasonable, and he is not a police officer or inspector, so he is ready to use a few micro-expressions to convict others: "The principal said so much, it is nothing more than that he feels that micro-expressions cannot be used as evidence in court." Actually, I'm not going to accuse anything, I'm just telling what I've seen. Yes, micro-expressions are very mysterious, it's not 100% accurate, but it's accurate for most people. As for the data in your hand, what micro-expression polygraphs can only achieve a very low accuracy rate, probably just because, the 20,000 testers who participated ......"

He paused and said unscrupulously: "It's just that you can't get home to see people's skills." ”

Chu Rusi's words were fluttering, but they hit the hearts of the parents heavily, they didn't believe that their son would take the initiative to beat someone, and now they ...... I didn't believe it anymore.

The principal was also a little unable to get off the stage, and secretly looked at Chu Rusi, who was this man, where did he come from, and what did he want to do, he smiled and played a round game: "The micro-expressions that the liar will appear are largely due to the nervousness of the speaker, and our instructor is still young, and it is the first time to deal with this kind of thing, so in front of your menacing parents, he is naturally a little nervous." It's normal for him to have some micro-expressions, and I hope you don't hold on to our instructor about this, because you have no evidence that he lied. The process and results of our investigation are rigorous and serious, so that everyone can listen carefully to the investigation process and then express their opinions. ”

Chu Rusi stretched out his hand very gentlemanly and motioned for the instructor to continue: "Okay, I will no longer pay attention to the micro-expressions, but to the content of your words. I will carefully scrutinize and find the right pressure point little by little, so that the front of the liars will completely collapse, don't worry, it's not a big problem, a steady batch, instructor, please continue. ”

The instructor has been awkwardly clubbing there, and he has been completely speechless by Chu Rusi, what is this man doing?

He was still immersed in shock, and was suddenly shocked by Chu Rusit, and his heart was furious, and his bestial instinct made him want to escape, otherwise he would have no bones. He always felt that this man had penetrated everything, watching them act as if he was watching the jumping clowns.

Not only this man, but also the student named Xu Yinuo, the eyes of these two people are simply printed in the same mold.

Slightly raised his chin, looking down at people, six points of calmness, three points of banter, and one point of ridicule.

The big and the small all looked at him like this, and he was hairy in his heart.

He clenched his fists, how could the iron-faced instructor of Tongcheng International Primary School, who was dignified, be bluffed by a parent and student?

He pretended to be calm and opened the folder and continued his performance, just talking about the 'eyewitness': "For the 'eyewitness', we conducted a careful cross-examination, and the process seen by the two is almost the same, the similarity is as high as 90%, and the process is reasonable, so it should be credible eyewitness testimony." Among them, out of consideration for the privacy of students, we must be anonymous for passing students. ”
