After dinner that day, Feng Junzi and Taomuling talked about Chang Wu's complaints during the day. Feng Junzi smiled and said, "You are afraid that Chang Wu and the others will be hurt. How did you think of making these suggestions? Let the public security organs give criminals a comfortable environment. How could they do it?"

Taomu Ling replied seriously: "It's not a criminal, it's a suspect."

Feng Junzi: "Okay, okay, it's the suspect. If I don't argue with you, just tell me what you think, right?"

Taomuling: "After this period of investigation, I discovered a very strange phenomenon. That is, ordinary people enter the gate of the public security organs and invisibly feel psychological fear and even a sense of guilt. This is abnormal, because most of them can be said to be innocent, and some people are not criminal suspects, but come to receive some normal administrative services, but when they enter the door, they seem to feel that they have done something wrong."

Feng Junzi nodded thoughtfully: "You continue to say."

Taomuling continued: "I also found that this phenomenon does not only exist in public security organs, but almost all government administrative organs here have this phenomenon to a greater or lesser extent. Many institutions that provide social administrative services will more or less feel a sense of mental pressure and fear when citizens do anything. I have observed it for a long time and feel that these people's self-feeling is not coming to receive services, but to cause trouble for the other party... If this psychological state appears in criminal investigation, it may be misleading, because the suspect will intentionally or unintentionally accept the hint that he may be guilty as soon as he stepped into the door of the public security organs. My research work has been greatly disturbed, and it is difficult to analyze the normal psychological state of these people."

Feng Junzi was silent for a long time and finally spoke: "Taomuling, you are not a sociologist or a politician. It is fruitless to be entangled in this issue in your cooperative research over the past few months. This is the environment you are in now. If you can't change it, then find a way to do what you can do in this environment... Forget it, let's not talk about this issue. You also made a suggestion about collecting materials for criminal suspects, which would make Chang Wu and the others exhausted."

Taomuling also smiled: "There is a reason. Recently, they are focusing on a vicious serial murder case. Judging from the scene, the victims of this case can be confirmed to be the same suspect, but these victims have no direct contact with each other, and the reconnaissance did not find any motive for the crime. If this murder case without direct motivation occurs continuously, it is likely to be related to the criminal's psychological disorder. To determine that the suspect may have serious psychological disorders, sufficient background materials must be analyzed."

Feng Junzi was also very interested when he heard this: "Oh! You used to be kind, but do you know how much work the grassroots police are now? Your requirements are impossible to complete. How is the case being investigated? Have you found a suspect?"

Taomuling: "The entire branch has been in trouble, but there are suspects. I also admire these policemen's perseverance in finding needles in haystacks. They had no other way, so they had to start with the people who might appear repeatedly at the crime scene. But the problem is that they have identified too many suspects and there is no direct evidence at all, so the reconnaissance has no way to start."

Feng Junzi blinked: "Taomuling, you should now think of a way that is beneficial to them and yourself. It is best to have short time and take effect quickly, and it sounds nice and has a bit of technical content. It is best to be able to associate with new technologies or new disciplines."

Taomuling: "What suggestions do you have? I am not a criminal investigation expert."

Feng Junzi: "They invited you not to come and cause trouble, but at least they provide some new ideas. The newer this idea is, the better. If you think about it carefully, you have never been exposed to psychological research on crime when you were in the United States? I am not referring to theory, but some specific inspection statistics and testing methods that can be used to bluff people."

Taomuling: "Breaking? I haven't learned this. But your words remind me of the research our tutor once did..."

...

A week later, good news came from Chang Wu. With the help of Taomuling, the public security organs finally determined the key suspects. Needless to say, the next thing was finally solved, under the strong pressure and sudden trial and training of the police officers, the case was finally solved. Chang Wu simply called Taomuling a god on the phone, and admired him very much. In fact, what Taomuling did was very simple. He did not need to hypnosis or psychoanalysis. He just sent all the suspects to the hospital for a brain wave scan, and immediately found that one person was abnormal. This person was in his thirties and had normal social records, but his brain wave frequency was much slower than that of normal people, similar to children in his teens. Taomuling also provided a research report on violent crimes of psychological disorders brought from the United States, which contained the statistical results of the common characteristics of brain wave scan.

Of course, the public security organs and Normal University were all very happy. The leaders who supported this project were also very happy. However, after Feng Junzi heard about this, he praised and criticized Taomuling's approach. He said to Taomuling: "You are really smart, almost at a glance. Your approach is exactly what they want. It not only solves the problem in front of you, but also connects it with the so-called scientific means. After solving such a big case during the research period, you can write a beautiful report. The leader's performance has added another point. In fact, your task has been completed so far."

Taomuling: "My mission has been completed? What are the project two months left?"

Feng Junzi: "What do you think they invited you to do? They are here to add glory instead of trouble. Now there is glory, and it is enough to solve major cases combined with modern scientific and technological means and the latest research results."

Taomuling asked in confusion: "Brain wave scanning is not a high-tech, it is just a routine medical examination. Related research has been done for a long time, so this is not a breakthrough."

Feng Junzi: "You are right. In fact, your approach is not scientific or even pseudoscience, but some people don't realize this, or try to promote things to the better."

Taomuling: "Pseudoscience? What does it mean?"

Feng Junzi: "This term is not easy to explain. Let me tell you, a 'scientific investigation law' was published in New Zealand in the 1970s. It was once very popular, but later it was found that the result was not very scientific. There is another example, that is, the author of "Shelf's Detective Collection", Conan Doyle, admired a Frenchman named Bettyon. This person was said to be a criminology authority at that time. His research results were to identify criminals based on measuring the length of various parts of the human body. This may make some sense and there are some statistics, but in today's police's view, this may be a farce... In fact, those who practice brain wave frequency can do it, and even I can do it..."

Taomuling: "I understand what you mean, but you may have misunderstood me."

Feng Junzi: "I am not the one who misunderstood you, but someone likes this kind of misunderstanding, and we can't do anything about it."
