Chapter 116 – Result – Part 24

Woojin asked Researcher Kim Hyeonja.

“How many people have you met while doing lie detection?”

Kim Hyeonja smiled warmly, like a neighborhood uncle, and said,

“I think I’ve met over ten thousand people while doing ‘lie detection’.”

“That’s amazing.”

Woojin slowly nodded his head.

No, he hadn’t.

Kim Hyeonja opened his mouth, maintaining a smile.

“Not everyone at the National Forensic Service knows Mr. Shin Woojin, but the DNA Department is very curious about what kind of person he is. You’re also very handsome.”

Woojin read curiosity in Kim Hyeonja’s expression.

Of course, his gaze, observing him at the same time, was no different.

He also complimented him and naturally repeated what he had said.

Backtracking was also hidden in his words.

Compliments and backtracking were techniques used to relieve tension in the other person while building rapport.

Not only that, but when he first entered the office, Researcher Kim Hyeonja was aware of the primacy effect.

He made a gentle expression, and his voice was bright with a moderate volume, articulated precisely.

When Woojin took his hand for a handshake, Researcher Kim Hyeonja’s hand was held perfectly vertical, not tilted up or down.

All of this contained hidden non-verbal cues.

However, there was one thing he couldn’t control: when he offered a handshake, his feet were fixed in an 11-shape.

This was akin to saying that he did not want to be disturbed by anyone while facing the person in front of him.

This was also a non-verbal cue that he wanted to focus on the other person and did not want to be disturbed by others.

And it seemed he had prepared before Detective Kim Taehyun and I entered the office.

The preparation was simple.

He put on the gown he had taken off.

Judging by the subtle wrinkles in the clothing, the gown had been hanging on a chair just moments before.

It was a good technique.

The gown was symbolic to the general public.

It could easily make ordinary people think of a professional, and unconsciously instill trust.

Conversely, wearing the gown also gives the wearer a sense of responsibility.

Humans are animals that adapt to their environment and utilize it.

In a high-end restaurant, one speaks and acts accordingly, and in a boisterous place, whether by choice or not, one’s voice inevitably gets louder.

What’s important here is that clothing is the same.

Depending on the clothes you wear, your concentration changes, you gain confidence, or conversely, the world seems gloomy and gray.

The clothes you pick out and wear when you go outside also affect yourself.

Researcher Kim Hyeonja put on her lab coat for her image and for herself.

Thus, observation reveals many things.

To understand these things, one must observe.

Observe.

With what kind of people is your surroundings filled.

And she realizes.

“It’s incredibly difficult to pinpoint a likely suspect before a forensic examination, you’re amazing.”

“Cause and result. When a cause begins, a result appears. All I did was speak based on that.”

Kim Hyeonja laughed at Woojin’s words, spoken so easily.

“Can I assume Mr. Woojin is specialized in profiling?”

“I think anyone can do it with enough practice.”

But they don’t.

Not only is there no need, but if you delve deep, it’s tiring and difficult.

When people encounter new things, if they don’t find them very interesting, they quickly give up or turn away.

Because a lazy brain dislikes concentration and is idle.

Desire designed by the environment one has lived in. It strongly craves only dopamine.

That’s why metacognition was important.

“Hahahaha! You’re being modest.”

Woojin turned his gaze to the black chair as if changing the subject.

“Do I sit there to do it?”

It was a lie detection chair.

“Yes. Since you said you wanted to try it. Shall we do it now?”

Researcher Kim Hyeonja also wanted Woojin to try it quickly.

It was because no comprehensive information could be gleaned from his tone and expression.

If I had a prosecutor take a look, I could figure out what kind of person he was, inside and out.

Most of all, as a researcher doing lie detection, I was curious how he had solved several unsolved cases.

“Thank you.”

Kim Taehyun folded his arms and watched Woojin sit in the chair.

Woojin, who once said he had many things he wanted to do, now works at the National Forensic Service and even sits in a lie detector chair.

Kim Taehyun chuckled and watched the scene.

Woojin watched Kim Hyeonja’s nimble hands connecting him to the machine to detect changes in his bodily functions such as heart rate, pulse, blood pressure, respiration, and sweat.

“I need to attach something to your chest, so I’ll lift your shirt for a moment.”

Woojin stopped her hand and turned his head to Kim Taehyun.

He would be worried.

If he saw the wound.

“I’m very shy, so I’ll attach it myself. I know where it goes.”

“Oh… really?”

Woojin didn’t lift his shirt but slipped his hand in to attach it to his chest, saying,

“I understand the accuracy of the lie detector is 97%, is that correct?”

The remaining 3% reflected the slight differences in physiological changes among individuals and the interpretation of the observer.

At Woojin’s question, similar words flowed from Kim Hyeonja’s lips.

“Different physiological changes vary from person to person…”

However, it is not adopted as legal evidence.

Conversely, it was sufficient to give impetus to investigations.

This applied not only to lie detection but to all departments of the National Forensic Service.

Kim Hyeonja, who was checking the attachments on Woojin, suddenly asked,

“We also have something called a thermal camera. We’re preparing to introduce it. Would you like to try that as well?”

Woojin nodded.

He sat in a chair that could even detect the clenching of his sphincter.

Woojin wanted to experience everything else there was, if anything, firsthand.

“Yes.”

With that, the preparations were complete.

Woojin’s face was captured by the thermal camera, and his heart rate, pulse, blood pressure, breathing, and other invisible autonomic nervous system responses were displayed on the screen.

Kim Taehyun, also seemingly interested, approached Kim Hyeonja, who was sitting in front of several monitors.

Just then, Woojin spoke.

“I think you can ask me anything.”

Researcher Kim Hyeonja smiled and said,

“Yes. You just need to answer ‘yes’ or ‘no’.”

Kim Hyeonja first asked neutral questions to check Woojin’s autonomic nervous system’s reaction to the truth.

“Is your name Shin Woojin?”

“Yes.”

As Kim Hyeonja had expected, the graph showing Woojin’s autonomic nervous system was stable.

“Do you live in Seoul?”

“Yes.”

“Are you a university student?”

“Yes.”

Kim Hyeonja nodded as if to say, ‘That’s enough.’

All the questions asked were truthful, and Woojin’s stable autonomic nervous system also indicated truth.

Furthermore, the temperature on Woojin’s face, captured by the thermal camera, did not rise.

Kim Hyeonja then asked the question she had been curious about.

Having conducted lie detection on over ten thousand people, she had seen countless individuals whose outward appearance differed from their inner thoughts.

Kim Hyeonja asked the question she had posed a moment ago.

“Can I assume that Mr. Woojin is specialized in profiling?”

Woojin clearly answered that anyone could do it with enough practice.

The Autonomic Nervous System would tell whether that was humility or if he truly believed it.

“Yes.”

Kim Hyeonja carefully watched the graph displayed on the monitor.

The graph was very stable, not fluctuating.

The front thermal camera also showed the same temperature.

“Do you have the ability to identify a criminal by observing a person’s actions and face?”

Woojin tried lying without hesitation this time.

The graph reflected in Kim Hyeonja’s eyes indicated truth.

“Were all the criminals you’ve identified so far just coincidences?”

“Yes.”

This also turned out to be true.

It was as if he had solved five cases by chance.

Kim Hyeonja blinked, raised her head, and looked at Woojin.

The protagonist who played a big role in catching criminals before forensic results came out was sitting here.

But all of that was just a coincidence?

There was no sign of eye movement indicating evasion, and even the Autonomic Nervous System, which could reveal his inner thoughts, was calm.

“Is it true that you identified them by coincidence?”

“Yes.”

This was also true.

Kim Taehyun, who was standing nearby watching the situation, scratched his head.

While a lie detector isn’t admissible as legal evidence, it was actually very helpful in investigating cases.

Detectives also had high trust in it.

But listening to what Woojin was saying now, wasn’t it like he had just stumbled upon the solutions to all those cases?

Kim Hyeonja then asked a question about desire.

“Do you eat when you’re hungry?”

“No.”

Truth.

“Do you dislike food?”

“Yes.”

Truth.

“Do you sleep less than three hours a day?”

“Yes.”

Truth.

“Do you love your family?”

“Yes.”

Truth.

“Do you love Detective Kim Taehyun?”

“Yes.”

Truth.

While Kim Taehyun smiled awkwardly, Kim Hyeonja looked back and forth between the graph and Woojin.

This couldn’t be happening.

No change.

The temperature, heart rate, breathing, and so on…

It was the same rhythm as the beginning.

Even his pupils were the same.

The graph showed Woojin’s autonomic nervous system, as if measuring a steadily running watch.

Conversely, Woojin was observing Kim Hyeonja.

She had a bewildered look on her face, as if she had never seen someone like him before.

Woojin slowly nodded, engaging in metacognition.

He still hasn’t reached ordinariness.

And by a lot.

The fact that an expert who had observed over ten thousand individuals showed such a reaction was proof of that.

If so, is it truly the right action to move by entrusting oneself to hormones?

So.

Is not controlling oneself considered ordinary?

As Woojin briefly thought about that and observed him, Kim Hyeonja muttered while looking at the thermal camera.

“This kind of thing is rare…”

No, there had never been such a case.

Even sociopaths or psychopaths would find it difficult to get these results.

At that moment, Kim Taehyun asked.

“Do you dislike 1++ No.9 (Beef)?”

“Yes.”

Kim Taehyun’s eyes widened.

“Woojin, you’re lying, aren’t you?”

“No.”

Truth.

“Are you sick of it?”

“Yes.”

Truth.

Kim Hyeonja, as if trying to understand the unprecedented situation she had never experienced since joining the National Forensic Service, kept alternating her gaze between the monitor, the thermal camera, and Woojin.

And when her gaze fixed on Woojin again, for some reason, many four-character idioms came to mind.

One mind, one body; unanimous; united in one will…

Kim Hyeonja’s upper body leaned forward slightly, and she opened her mouth.

“If your family or acquaintances were involved in a criminal case, would you be able to fully entrust the judgment to the law?

At that moment.

Woojin’s pupils, looking at Kim Hyeonja, expanded like black holes.

“Yes.”

The calm graph began to fluctuate wildly.
