If economic factors are excluded, could it be that the Blue Lake is conservative, but in recent years, the new generation has been influenced by Internet thinking, has an open personality, and the concept conflict between the older generation and the new generation has led to an increase in the suicide rate?

Could it be that there are mistakes in urban planning and construction, and the living space is compressed, which affects people's psychology, which leads to an increase in the suicide rate?

There are many, many possibilities, and each one has a certain possibility. However, it is very unlikely that it will be a criminal offence.

Hundreds of eucalyptus pieces in a row have not found any clues to criminal offenses, this is always a real reality, right?

Feng Guozhu was a little unwilling, but he knew that he could only accept this result.

The superior seemed to see his emotion, and said, "If you want to check, you can check again." Also, it's up to you to find a team of social psychologists. In terms of funding, I can approve some for you. ”

Feng Guozhu breathed a sigh of relief.

That's okay and acceptable.

"Thank you, leader."

He had already made up his mind. While looking for a team of psychologists to do a public psychological survey, you also have to check it yourself.

At this moment, he already has an investigative idea.

With the funds in his hand and the authorization of his superiors, Feng Guozhu immediately took action. He started to make connections, and soon contacted the deputy dean of the psychology school of a university in a nearby city, and was introduced by the vice dean to find a psychology professor named Yang Liu.

In the face of Feng Guozhu's invitation, Professor Yang Liu was very happy.

"I've recently been working on a project with graduate students on the impact of technological developments in modern society on suicide rates. Blue Lagoon's suicide rate has been on the high side for the past two years, and it's a good sample for study, and I've wanted to study it for a long time. ”

Professor Yang Liu is less than forty years old, well-maintained and intellectually elegant. She smiled and said: "It's just that the research funding is not easy to apply, and I haven't been able to make it." If you can afford to pay for your research, I'm ready to go. ”

With the funds approved by his superiors in his hand, Feng Guozhu was rich and wealthy, so he agreed in one bite: "This is no problem." ”

"That's good."

Yang Liu bowed his head and was a little curious: "But this kind of thing ...... It doesn't seem to be under the control of your security bureau? Why did you come forward? Is there any criminal case involved? Or do you already have some clues? ”

Only in this way is it reasonable for the Public Security Bureau to intervene.

Feng Guozhu couldn't explain too much, so he could only say with a lake: "It's really a little suspicious, and it's currently under investigation." The specific results depend on the conclusion of Professor Yang's investigation. ”

"That's right, that's fine. I'll form a team and I'll be able to go the day after tomorrow. ”

After finalizing this matter, Feng Guozhu returned to Blue Lake City non-stop, gathered his subordinates again, and arranged the matter.

"There's definitely something weird in this."

The vigilantes nodded heartily.

Where there is an effect, there must be a cause. Even if the Blue Lake City has a high suicide rate due to bad feng shui, this can be regarded as the reason, right?

If you don't check it out, wouldn't you wear this uniform in vain?

"In terms of criminal investigations, we don't have to waste our efforts anymore. One is that there are hundreds of eucalyptus, and we don't have so many manpower and funds to check them one by one, and the other is that even if we have manpower and funds, we can't find anything. If it was possible to find out, the brother team would have found out long ago.

In terms of social psychology, I also asked Professor Yang Liu to lead the team to investigate, and we don't have to worry about this.

Let's just focus on one line to investigate, that is, what these unreasonable suicide victims have in common! ”

The three words "common ground" are Feng Guozhu's investigation ideas.

If these unreasonable suicides are deliberately carried out by some hidden force, then there must be a standard when they select victims, right?

In the past, some serial killers sometimes selected specific people, such as certain customs practitioners. Once you've identified common ground, it's time to move forward.

The task was assigned, and a dozen or so vigilantes under his command immediately split up.

The suicide dossier could not have been too detailed. There are many things that need to be investigated by the vigilantes.

The day after tomorrow, Professor Yang Liu also brought several young male and female students who looked like Sven Wen to Blue Lake City. After a night's rest, the next day they also began their investigation.

Before leaving, Professor Yang Liu had already worked out an investigation plan with the students. Just follow the steps at this moment. In the face of this rare practical opportunity, maybe it also involves their own studies, and the students are also doing their duty one by one.

On the first day, with the assistance of Feng Guozhu, Professor Yang Liu first retrieved meteorological data, economic and demographic data, urban construction data, and even birth rate, urban population inflow and outflow data over the years, average household car ownership rate, per capita disposable property, average life expectancy, infant mortality rate, average number of sunny days, cloudy days, rainy and snowy days, environmental pollution data, per capita alcohol consumption, and so on.

This made Feng Guozhu couldn't help but be surprised in his heart.

"These data ...... Is it also related to suicide? ”

"Of course it does." Professor Yang Liu explained with a soft smile: "It's like weather data. When it's cloudy, don't you bother to go out? If there is no sunshine, is it easy to be depressed? The economic data is more direct, and if you don't have money in your hand, is it stressful? If the per capita alcohol consumption is high, does it mean that people have a higher need to relieve stress? These data will eventually be reflected in the final suicide rate figures. ”

At this moment, Feng Guozhu had a thought in his heart.

This is called professionalism!

He used to think that suicide was more random and idealistic. But now, Professor Yang Liu's team is clearly studying it as a science that can be accurately measured by numbers.

Feng Guozhu didn't know what to do.

"That...... There's so much data, that's enough, right? ”

Professor Yang Liu shook his head with a smile: "This is where it goes, it is far from enough." Later, we have to conduct field surveys, distribute questionnaires, and so on. When looking at data, you can't just look at the macro, but also look at the micro. ”

Sure enough, the next day, the students of the Yang Liu team took to the streets. With small gifts purchased in bulk, they set up stalls in different places such as subway stations, shopping malls, pedestrian streets, urban villages, urban suburbs, and school gates, and began to gather people on a large scale to fill out the questionnaire with the slogan of giving free gifts.

Although those gifts are cheap, they are some daily use, such as shampoo, paper pump, toothpaste, toothbrush, basin, eggs, salt, noodles, etc.

And there is no personal privacy involved in the questionnaire. Personal name, place of origin, ID number, contact information are not asked, only some are specially designed, such as "what level of stress do you feel you have been facing in the near future, on a scale from 0 to 9", "what is the source of the most stressful things for you recently", "personal monthly income", "how do you feel about the weather recently" and so on.

After filling it out, it will not be viewed on the spot, just put the questionnaire in a sealed box.

In this way, people are relieved of their worries and can ensure the authenticity of their answers as much as possible.

Feng Guozhu worked hard to apply for the funds, so they turned into a mountain of small gifts and then distributed to the people, in exchange for the answers on the questionnaires.

Professor Yang Liu's team is busy, and Feng Guozhu is not idle. Over the course of a few days, his vigilantes were on the move, and soon, a large amount of information was gathered in his office.

In the evening, the vigilantes gather to analyze the information collected during the day and begin to carefully sift through it.

Originally, Feng Guozhu thought that this work should not be difficult to do. But as soon as the analysis began, he realized he was wrong.

He found it difficult to classify the dead involved in unjustified suicide with a uniform label.

Economic conditions?

Some of these people have rich families, and the richest ones have estimated hundreds of millions of family assets. The poorest are in debt of hundreds of thousands because their family members are seriously ill, and they have to be busy on the construction site all day long.

Occupation?

These people's occupations range from white-collar workers, teachers, construction workers, restaurant owners, and so on.

Age?

From small to large. The youngest is in secondary school, and the oldest is retired.

Disease?

Some people are in good health, some people have just recovered from a serious illness, and some people are suffering from chronic diseases.

A meeting point of space-time?

There is no one place or event that these people have been there or have done. Some of these people are atheists, some believe in gods, and none of them have done a certain ritual, worshiped a certain god, and so on.

Feng Guozhu was busy for more than half a month, but in the end he found nothing.

At this moment, he began to suspect even himself that these people were committing suicide...... Are they all reasonable, and the so-called unreasonable is just their own personal suspicions?

Under such circumstances, he had to pin his hopes on Professor Yang Liu.

In any case, there must be an explanation for this. Even if there is no premeditated or organized criminal group, it is acceptable for Feng Guozhu to find an answer from the aspect of social psychology.

Blue Lake City is Feng Guozhu's hometown. He was born here, grew up here, got married, had children, and has been working here. For the sake of his hometown, he must find out the truth.

You can't really say that there is a problem with the feng shui in Blue Lagoon, right?

As a native of Blue Lagoon, he couldn't accept that.

Professor Yang Liu's work is now nearing its end. Now that all the data that should be collected has been collected, it shouldn't take long for the analysis to work, right?

On the third day, Feng Guozhu saw Professor Yang Liu, who had no intellectual elegance at all, and his face was haggard at the moment, and his hair was slightly greasy.

"Let's get to the point."

Professor Yang Liu's voice was a little hoarse: "My team collected all the data and did all the work that could be done, and we agreed that the suicide rate in Blue Lake City should be lower than the average compared to other cities." The number should be roughly between 10.9 and 12.1 suicides per 100,000 people per year. ”

This figure is 15.60% to 4.13% lower than the average.

Previously, after removing the suicide eucalyptus between the obviously unreasonable and ambiguous, Feng Guozhu came up with a figure that was only 1.59% higher than the average.

Feng Guozhu knew that among those suicides, there must be some cases of unreasonable suicides, but he could not screen them out.

I just screened by the unsatisfactory events that happened in my life before I committed suicide.

Where there is a relatively large unsatisfactory incident, it is to be regarded as a reasonable suicide. If not, it will be regarded as unreasonable suicide.

Is it possible, then, that some people would not normally commit suicide even though they had a large and unsatisfactory event in their lives before committing suicide that would be sufficient to justify suicide?

There must be such people. But Feng Guozhu couldn't screen them out.

Removing the obviously unreasonable and ambiguous suicides, and then removing these cases that have reasons to commit suicide but will not commit suicide under normal circumstances, Feng Guozhu believes that the final value can probably be consistent with the final data provided by Professor Yang Liu.

The combination of the two further verified Feng Guozhu's guess. That is, there are indeed abnormal suicides, and there are quite a few of them.

A security officer muttered, "Professor Yang, how can this predicted value not match the actual value?" ”

"Normally, this means that there is an error in the prediction and calculation model. We usually check the model in turn to eliminate errors. But...... This time, we didn't find anything wrong in the model. ”

She shook her head again, "I'm sorry. Social investigation and psychology are not omnipotent, nor do they fully reflect human social life. The data I have provided is for reference only. Why is the suicide rate so high in Blue Lake City...... I can't answer that question. There's nothing I can do. ”

Feng Guozhu sighed: "Professor Yang, thank you very much for your work. ”

Yang Liu looked at the students sitting next to him in the meeting, and saw that the students' faces were full of frustration.

After being busy for more than half a month, the result is nothing, this kind of thing is not something that everyone can do.

"That'...... I'm sorry. Let's go first. ”

The willow team leaves. The security guards looked at Feng Guozhu.

"Team Feng, what should I do next?"

He waved his hand a little tiredly: "Seal the file." Report the results and let the boss handle it. ”

He really couldn't find out.

As he expected, after the report, there was no response. Obviously, the superiors did not believe that the investigation needed to be reopened.

He can also understand this. After all, in this case, the evidence that proves that there is no anomaly in this event is too much and too convincing. There is too little evidence to prove that there is an anomaly in this incident, and there are only some speculations and unclear figures, which are not convincing at all.

Time passed quietly, and years passed in the blink of an eye. Feng Guozhu gradually got older, and finally after seven years, he retired from the first line of criminal investigation and turned to the second line to do some management work.

This matter was also buried in his heart, and he never told anyone about it again.

It wasn't until the young, newly recruited vigilante was full of excitement and excitement that he came to him as if he had discovered something big.

"Leader, this suicide is not normal! I suspect it wasn't suicide, it was him! You see, the global average suicide rate last year was 12.3 per 100,000 people......"
