Woojin asked researcher Kim Hyeonja.
“How many people have you met while doing lie detection?”
Kim Hyun-ja said with a warm smile like a neighborhood uncle.
“I think I’ve met over ten thousand people while doing ‘lie detection.’”
“You are amazing.”
Woojin nodded his head slowly.
I thought that someone who had measured that many lies could use the researcher as a mirror to look at himself.
Kim Hyun-ja opened her mouth while maintaining a smile.
“Not everyone at the National Forensic Service knows Mr. Shin Woo-jin, but the DNA department is very curious about what kind of person Mr. Woo-jin is. He’s also very handsome.”
Woojin read curiosity in Kim Hyunja's expression.
Of course, his gaze was also observing himself at the same time.
Also, compliment them and naturally repeat what they said.
There is also backtracking hidden in his words.
Compliments and backtracking were used as a way to build bonds while relieving tension in the other person.
Moreover, when she first entered the office, Researcher Kim Hyun-ja was aware of the Primacy Effect (the effect in which information received first has a stronger influence than information acquired later).
He made a gentle expression and pronounced the words accurately in a bright voice with an appropriate volume.
When he took her hand to shake hands, Researcher Kim Hyeon-ja's hand was in a perfectly vertical shape without tilting up or down.
There was a hidden, nonverbal message in all of this.
But there was one thing I couldn't control: when I was shaking hands with him, my foot shape was fixed at the number 11.
This seemed to mean that he did not want to be disturbed by anyone regarding the person in front of him.
This seemed to indicate that he wanted to focus on the other person and was a nonverbal way of saying he didn't want to be disturbed by others.
And before Detective Kim Tae-hyun and I entered the office, it seemed like preparations had been made.
The preparation was simple.
I put on the gown I had taken off.
Judging by the subtle wrinkles in the garment, the gown had been hanging on the chair a moment ago.
It was a good method.
The gown was symbolic to the common people.
It was easy to make the general public think of a professional, and it was able to instill a sense of trust unconsciously.
Conversely, the person wearing the gown is also given a sense of responsibility.
Humans are animals that adapt to their environment and utilize it.
If you go to a fancy restaurant, you have to speak and act accordingly, and if you go to a noisy place, you can't help but raise your voice, whether you want to or not.
The important thing here is that the same goes for clothes.
Depending on what you wear, your concentration level can change, your confidence can increase, or the world can appear gloomy and gray.
The clothes you wear when you go out also affect you.
Researcher Kim Hyeon-ja wore a gown, both for her own image and to show herself.
In this way, observation tells us many things.
To know these things, you have to observe.
Observe.
What kind of people are filling your surroundings?
And recognize.
“It’s not easy to pinpoint a prime suspect before the forensic examination is done, so this is amazing.”
“Cause and effect. When the cause starts, the effect appears. That’s all I’ve seen and told you.”
Kim Hyun-ja laughed at Woo-jin's words, which were spoken so easily.
“Can we assume that Mr. Woojin is specialized in profiling?”
“I think anyone can do it if they practice enough.”
But it doesn't.
There is no need to do that, and it would be tiring and difficult to go into it in depth.
When people accept new things, if they are not very interested, they quickly give up or turn their backs.
Because a lazy brain hates concentration and is lethargic.
A desire designed by the environment in which one lives. A strong desire for dopamine alone.
That's why metacognition was important.
“Hahaha! How humble.”
Woojin turned his gaze to the black chair as if changing the subject.
“Are you going to sit over there and do it?”
It was a lie-detecting chair.
“Yes. Since you said you wanted to try it. Should I try it now?”
Researcher Kim Hyeon-ja also wanted to receive it from Woo-jin quickly.
This was because no comprehensive information could be gleaned from the tone of voice and facial expressions.
If you take a test once, you can find out what kind of person you are inside and out.
As a researcher who specializes in lie detection, I was curious about how some of the unsolved cases were solved.
"thank you."
Kim Tae-hyun crossed his arms and watched Woo-jin sit down on the chair.
Woojin, who said there were many things he wanted to try, has now entered the National Forensic Service and is sitting on the lie detector chair.
Kim Tae-hyun watched the scene with a smirk.
Woojin watched the movements of Kim Hyunja's hands as she connected herself to the machine to monitor changes in her bodily functions, such as heart rate, pulse, blood pressure, breathing, and sweating.
“I need to put it on my chest too, so I’ll take off my clothes for a moment.”
Woojin turned his head to Kim Taehyun, blocking his hand.
I think I'll be worried.
If you see the wound.
“I’m shy, so I’ll put it up myself. I know where to put it.”
“Ah… Is that so?”
Woojin said, without lifting his top, he put his hand in and attached it to his chest.
“I heard that the lie detector is 97% accurate. Is that true?”
The remaining 3% was a percentage that reflected the physiological changes that vary from person to person and the slight differences in the observer's interpretation.
In response to Woojin’s question, similar words came out of Kim Hyunja’s mouth.
“Each person has different physiological changes… … .”
However, it is not accepted as legal evidence.
On the contrary, it was enough to give elasticity to the investigation.
It was not only lie detection, but all the departments of the National Forensic Service had the same meaning.
Kim Hyun-ja, who was checking the things attached to Woo-jin, suddenly asked.
“A thermal imaging camera. We’re preparing to introduce a new one, so should we get that one as well?”
Woojin nodded.
I sat on a chair that could detect even the tightening of my sphincter muscles.
Woojin wanted to experience everything that was different.
"yes."
So the preparations are complete.
The front of Woojin's face was captured by a thermal imaging camera, and his invisible autonomic nervous system, including heartbeat, pulse, blood pressure, and breathing, were recorded on the screen.
Kim Tae-hyun also seemed interested and approached Kim Hyeon-ja, who was sitting in front of several monitors.
At that time, Woojin said.
“I think you can ask any question you want.”
Researcher Kim Hyeon-ja said with a smile.
“Yes. You can answer with ‘yes’ or ‘no.’”
First, Kim Hyun-ja asked questions to check Woo-jin's autonomic nervous system's ability to respond to the truth through neutral questions.
“Is your name Shin Woo-jin?”
"yes."
As Kim Hyun-ja had expected, the graph showing Woo-jin's autonomic nervous system was stable.
“Do you live in Seoul?”
"yes."
“Are you a college student?”
"yes."
Kim Hyun-ja nodded as if to say that this was enough.
Everyone asked honest questions, and Woojin's stable autonomic nervous system also told them the truth.
Also, the temperature of Woojin's face captured by the thermal imaging camera did not rise.
Kim Hyun-ja now asked the question she had been wondering about.
Having performed lie detection on over ten thousand people, I have seen countless instances of people being two-faced on the outside and inside.
Kim Hyun-ja asked the same question she had asked a little while ago.
“Can we assume that Mr. Woojin is specialized in profiling?”
Woojin clearly answered that anyone can do it if they practice enough.
Your autonomic nervous system will tell you whether that statement was meant as humility or if you really thought it was.
"yes."
Kim Hyun-ja looked closely at the graph displayed on the monitor.
The graph was very stable and did not fluctuate.
The front thermal imaging camera also showed the same temperature.
“Do you have the ability to determine a person’s identity by looking at their actions and face?”
This time, Woojin lied without hesitation.
The graph reflected in Kim Hyun-ja's eyes told her the truth.
“Have all the culprits you’ve pointed out so far been coincidences?”
"yes."
This also turned out to be true.
It was like saying that five cases were caught by chance.
Kim Hyun-ja blinked, raised her head, and looked at Woo-jin.
Here sits the protagonist who played a major role in catching the criminal before the forensics came out.
But that was all just a coincidence?
There was no sign of avoidance, such as eye shaking, and even the autonomic nervous system, which can see inside, was calm.
“Is it true that you pointed it out by chance?”
"yes."
This time it was true.
Kim Tae-hyun, who was standing to the side and watching the situation, scratched his head.
Although lie detectors are not admissible as legal evidence, they can be a huge help in actually investigating cases.
The detectives' credibility is also high.
But if you listen to what Woojin is saying now, isn't it similar to saying that he's guessed all the incidents so far?
This time, Kim Hyun-ja asked a question about desire.
“Do you eat when you are hungry?”
"no."
truth.
“Don’t you like food?”
"yes."
truth.
“Don’t you sleep more than 3 hours a day?”
"yes."
truth.
“Do you love your family?”
"yes."
truth.
“Do you love Detective Kim Tae-hyun?”
"yes."
truth.
While Kim Tae-hyun laughed awkwardly, Kim Hyeon-ja looked back and forth between the graph and Woo-jin.
This couldn't be happening.
There is no change.
Temperature, heart rate, breathing, etc…
It was the same rhythm as the first time.
Even the pupils were like that.
The graph showed Woojin's autonomic nervous system, like measuring a clock that is running at a constant rate.
On the other hand, Woojin was observing Kim Hyeonja.
He had a puzzled look on his face, and it seemed like he had never seen anyone like him before.
Woojin nodded his head slowly while doing metacognition.
He himself is not yet ordinary.
That too, a lot.
The evidence was that experts who had observed over ten thousand opponents showed such behavior.
So is it really right to let your hormones control your movements?
therefore.
Is it normal to not be able to control yourself?
While Woojin was observing him with that thought for a moment, Kim Hyunja muttered while looking at the thermal imaging camera.
“This kind of thing doesn’t happen often… … .”
No, there was no such case.
Even sociopaths and psychopaths would have a hard time achieving these results.
Then Kim Tae-hyun asked.
“Do you hate 1++Number Nine?”
"yes."
Kim Tae-hyun's eyes widened.
“Woojin, are you lying?”
"no."
truth.
“Are you tired?”
"yes."
truth.
Kim Hyun-ja kept looking back and forth between the monitor, the thermal imaging camera, and Woo-jin, as if trying to understand the unusual situation she had never experienced before at the National Forensic Service.
And when I focused on Woojin again, for some reason, idioms kept coming to mind.
One mind and one body, unanimity, unity… … .
Kim Hyun-ja's upper body tilted forward slightly and she opened her mouth.
“If your family or your acquaintances were involved in a crime, would you be able to leave it entirely to the law to judge?
moment.
Woojin's pupils dilated like a black hole as he looked at Kim Hyunja.
"yes."
The once calm graph began to shake like crazy.
