The two came to the police station.
Fang Mo immediately brought Yang Xueqi to the office, took out the surveillance video, and said, "Look at this."
Yang Xueqi was slightly startled, but still took the laptop and looked at it seriously.
The content at the beginning of the video was no different from what Fang Mo saw when he first watched it.
But when Xu Mo left the room and came back again, his overall condition was very problematic.
Xu Mo opened the door, returned home, and put on his shoes skillfully.
Then he started touching the shoe cabinet, then walked around the room and looked at the room.
This look is like a person who has been away from home for a long time. When he returns home again, he can't help but touch and look here and there.
Especially when Xu Mo looked at the drawn curtains and the monitoring probe, he subconsciously frowned and his lips moved, as if he said something.
Unfortunately, the time was too short to see clearly what he said.
After Xu Mo walked around all the places, he began to tidy up the room.
Even though the room was already tidy, he still tidied it up, as if he had obsessive-compulsive disorder.
After doing this, Xu Mo went to the bathroom.
When he came out again, he had changed his clothes.
A black sweatshirt with a hood, a black mask, black gloves, and a black backpack.
After coming out of the bathroom, Xu Mo went out again.
Seeing this, Fang Mo pressed the pause button and turned to look at Yang Xueqi.
Yang Xueqi knew what Fang Mo wanted to ask, but she didn't rush to give an answer. Instead, she asked, "Is this why you suspect he has multiple personalities?"
Fang Mo nodded and immediately asked, "Is this multiple personalities?"
Yang Xueqi played the video back and watched it again. Then, with Fang Mo's expectant eyes, she slowly shook her head and said, "Judging from his behavior alone, he does look like a second personality, but it's all disguised." .”
"What? Disguise?"
Fang Mo looked at Yang Xueqi in disbelief and subconsciously said, "How could this be a disguise?"
At this moment, he couldn't help but begin to doubt Yang Xueqi's professionalism.
However, Yang Xueqi said calmly: "Captain Fang has been a police officer for many years, and he should have encountered some criminal suspects who, in order to avoid punishment, said that they had mental illness, such as split personality or something. Faced with such a person, what would Captain Fang think? ?What will you do?"
"If the other party is pretending, we can tell."
"Then on what basis do you judge that the other party is pretending?"
"Of course it's his words and demeanor, as well as his previous performances."
"What if the other party is disguised well?"
"We will send each other to undergo a psychiatric evaluation and also pass a lie detector test."
Yang Xueqi nodded.
Mental illness is not that easy to disguise. Most people think that mental patients are the kind of people who yell, talk nonsense, and behave strangely. Therefore, when they pretend or imitate, they will pretend according to their own understanding of mental patients. .
This approach seems very smart, but it is actually very stupid.
Most mental patients actually know that they are sick, but they do not think it is an illness. Many mental patients are just cognitively different from ordinary people, but they have a complete set of logic of their own.
Simply put, mentally ill people are sick, but they are not stupid.
Many mentally ill people are even smarter than some normal people.
Therefore, if you want to disguise yourself as mentally ill, you must first construct a clear and rigorous logic that is different from common sense, and then make different reactions based on this logic.
But no matter how the average person constructs it, he can't escape from his existing cognition.
Therefore, when they deliberately behave like a mental patient, it looks funny and ridiculous, and ordinary people can see it.
But there are also some people who are smarter and do not pretend to be mentally ill to construct a second personality.
This kind of people will not yell or anything like the previous people. They will use some small actions, such as talking to themselves, changing their temperament, denying the existence of certain things, etc.
In this case, the first thing people think of is that this guy is sick, and people who know something about psychology will take it for granted that this guy has multiple personalities.
However, such a person can be detected by simply submitting to a psychiatric evaluation or using a lie detector.
Of course, there are some people who are undetectable, but they are already pretending.
However, there are conditions required to do this.
First, they must have a set of behavioral logic and cognition that is different from the subject.
Simply put, they must invent a fictional person.
The fictional person must be different from the subject and must be inextricably linked to the subject.
If you want to do this, you can't do it without a certain IQ.
Second, they must hypnotize themselves into believing that they do have a second personality.
Only then can they pass the polygraph.
But self-hypnosis is not that easy.
What's more, according to medical research, in many cases, the main personality is unaware of the existence of the second personality, and the second personality will not appear easily.
To be precise, every time the second personality appears, there is a certain pattern and it will not appear without warning.
After all, the second personality is not the main personality in the final analysis.
However, it is not that easy to escape legal sanctions by forging a second personality.
Let’s not talk about how to pass the mental evaluation. Even if it passes, the police can determine whether the other party has lost behavioral and cognitive abilities based on his performance when engaging in criminal activities.
Generally, people with multiple personalities have not lost their behavioral or cognitive abilities, so they will still be sentenced.
After putting in so much effort, the ending still cannot be changed in the end, so what’s the point of doing so?
After explaining this to Fang Mo, Yang Xueqi pointed to the video and said: "It is difficult for non-professionals to judge whether a person has a second personality, but you can still tell whether a person is pretending."
When Fang Mo heard this, he frowned and asked, "Why would he do this?"
Yang Xueqi shrugged and said: "I don't know about this, but I am sure that he must have his own purpose for doing this."
Immediately, Yang Xueqi asked how Fang Mo obtained this video.
Fang Mo naturally didn't hide anything and told everything in detail.
After hearing this, Yang Xueqi also frowned, looked at the video, and then looked at Fang Mo.
Fang Mo felt uncomfortable being looked at by Yang Xueqi and couldn't help but ask, "What's wrong? Why are you looking at me like that?"
"Captain Fang, I remember you said before that you couldn't be sure whether the person who attacked Xu Mo in the 404 case was Chen Shi. You and Xu Mo both suspected that there was a sixth person at the scene, right?"
Fang Mo nodded.
"Xu Mo has always suspected that someone is spying on him, right?"
Fang Mo nodded again.
"Then I probably guessed his purpose."
