MTL - Survivorship Bias-Chapter 2 The golden mean

"It turned out to be the blame." The boy beside him finally spoke.

An Wujiu turned his face, and caught a small expression of satisfied curiosity on his too cold face. His name was also suspended, Wu You.

"Ah, I'm also curious about this." The beauty on the right also spoke, with the words [Zhong Yirou] floating in front of her. She rested her chin with her palm and tapped her fingernails on her cheek, "This name doesn't look like a poor man who will come to the competition at all."

She wears berry-colored lipstick, her eyes are big and beautiful, "Your neck..." Zhong Yirou stretched out her finger and pointed to the side of An Wugui's neck, and moved closer, "This flower Is it tattooed?"

"Flower?" An Wujiu bowed his head. Seeing that he couldn't see, Zhong Yirou spread out her left palm and placed it in front of An Wujiu, with a small round mirror embedded in her palm, "Here, this white one is pretty good looking."

From the reflection of the mirror, An Wujiu found a large cluster of flowers on his neck, the snow-white slender edge outlines the blooming shape, the petals are complex, layer upon layer, obliquely upward from the left clavicle , winding all the way to the back of the right ear.

But he doesn't seem to have any of these flowers in his memory.

“I don’t remember either.” An Wujiu put his fingers on it, rubbed the skin red, but couldn’t get it off.

Is it really a tattoo.

"Peony." Wu You on the side interjected, but quickly added in a low voice, "It seems to be."

Zhong Yirou was very surprised, "Peony? Have you ever seen a peony flower? Now this ornamental flower is almost extinct."

In this world of land and water pollution, not to mention ornamental vegetation, there is not much soil for food crops to grow.

Wu You pursed her lips, "My mother..." As if he felt that he had said something wrong, he stopped and explained perfunctorily, "My family has a collection..."

Zhong Yirou felt even more strange after hearing this, "What kind of rich and noble family are you?"

"Fake." Wu You pressed the brim of his hat, lying on the table with his hands folded, "artificial."

"I see." The doubts on Zhong Yirou's face did not disappear completely, she put away her small mirror and observed the skin on An Wujiu's neck again, and said to herself: " It doesn't look like a tattoo...it doesn't look like an artificial skin."

An Wujiu didn't think about the strange peony pattern on his body anymore, after all, he has lost his memory now, and thinking about it is useless.

He bowed his head slightly, and caught a glimpse of Zhong Yirou's cheongsam, revealing the straps on her legs. The skin on her left calf is not the same as the other parts. It should be a whole piece of artificial grafted skin, made of shark cartilage polysaccharide, which is eerily smooth.

In addition, she carried a roll-shaped bag diagonally behind her. The index and middle fingers of both hands had thin calluses, and there were slight knife wounds on the sides of the fingers, which were very sharp The slender shape that can only be created by a knife, the nails are very short and red nail polish is applied, and a little black thing is rubbed on the end of the little finger.

Oil?

The voice sounded again, An Wujiu stopped observing.

"This warm-up game is called, and the rules are very simple."

A holographic projection is projected on the desktop, which is a display screen with eight numbers constantly rotating.

"Among the 100 natural numbers from 1 to 100, each of you needs to take one of them and write it with your finger on the handwriting screen in front of you."

The rotation on the eight displays stopped, eight numbers appeared at random, and then a new number appeared above the eight displays, "Sum the eight numbers and divide by 8 , to get a mean."

“The one who is closest to 1/2 of the real average will be the winner of the warm-up game and enjoy the advantage of the official game and the right to decide the competition system.”

"Give everyone five minutes to think and write down your answers in five minutes."

"The timer begins then."

The countdown number appeared on the round table, which instantly became 4 minutes and 59 seconds, and kept decreasing. The noise that had just subsided appeared again, An Wu Jiu's forehead was soaked with cold sweat, and his hands began to tremble again. He took his hand under the table and tried to clench it tightly, only to hear a brawny man on the opposite side say, "I actually got a math problem for Lao Tzu."

An Wujiu stared at the brawny man who just spoke, his name was Liu Chengwei, he looked quite old, at least thirty years old, but he dressed like a gangster, with many arms on his arms Small pinholes, both fists are covered with metal exoskeletons, but the material is average.

The eyeball in the orbital bone was atrophied and grey.

Wu You is still playing the Rubik's Cube in his hand, bowing his head without raising his eyelids, "Have you never even learned arithmetic?"

These words were bad, and Liu Chengwei was immediately irritated by him, "Can you talk, kid?" He glanced at the ill-fitting old clothes on Wu You's body, "Do you think you are like this? , does he look like someone who went to school?"

This world is completely capitalized.

Capitalists who occupy nearly 90% of the world's wealth enjoy and waste excess resources, including education. The essence of class solidification is to master the cognitive ability of the lower class, so the compulsory education system for all has long since disappeared. Basic mathematics education is expensive, and a complete system of basic subject education has discouraged many poor people, not to mention physics, astronomy or artificial intelligence.

Want to understand the nature of the world?

You have money.

Wu You rolled her eyes, "At least I'm not illiterate."

"Well, I'm sorry to interrupt everyone..." A boy who looked dull, wore glasses and freckled couldn't help but persuade him, "It's just guessing the number, it's not It's a difficult question, let's not quarrel."

The name floating in front of him is [Ueno Taisei], a Japanese. Judging by the mouth shape, it seems that he speaks Japanese, but what An Wujiu hears is Chinese.

Ueno's words did not make Liu Chengwei relieved, but the other party poured his anger on him, "What are you talking about, a poor **** who can't even afford implantable glasses!"

"I...I'm sorry." Ueno's words came to his mouth and he swallowed again, embarrassedly pushing the old glasses on the bridge of his nose that he had used for several years.

"What he said is not wrong. It's not difficult. Shengyin said it just now, and finally compare it with the average of 1/2 of the sum of all numbers." Zhong Yirou smiled coquettishly Qiao, pointed at the people on the table one by one, "You choose 10, you choose 20, and so on..." She turned to look at An Wu Jiu, and pointed at him with her long fingers, "Finally, if it comes to you, if You choose 80, eight people, the final average is 45, take one half, that is, the people who choose 22 and 23 are the closest."

After finishing speaking, Zhong Yirou smiled, "It's not difficult to calculate, but who can guess which number each other will choose?"

"That's right." The middle-aged man Yang Ming, who had been targeting An Wujiu, said, "This warm-up game is also strange, it's all based on luck."

An Wujiu stared at his face, this man can hide his tone when he speaks, but the subtle expressions on his face are not hidden well enough.

“What does Mr. Yang do?” Zhong Yirou smiled and turned the topic to an irrelevant direction, but it coincided with what An Wujiu thought, “I feel like you are wearing a tie. Shirts, compared to the rest of us, are a lot more serious."

Her tone was teasing and joking, and it really didn't sound serious.

This is a great observation point. An Wu Jiu silently watched everyone in his sight, Wu You didn't react much, he still played the Rubik's cube, Liu Chengwei looked like he was watching a play, he was very interested in the hints of beautiful women, the old man held a pen in his hand, he didn't seem to care too much This sentence, just thinking for himself, the freckled man with glasses glanced at Zhong Yirou timidly.

An Wujiu's observation eyes fell on the face of the mechanical Guanyin directly opposite him, but found that the other party was facing him with the Guanyin statue, motionless, and seemed to be staring at him.

"Office worker is good." Zhong Yirou smiled brightly, "We want to be an office worker in our society, I don't know how highly educated, the competition is so great." She seemed to feel hot, Deliberately unbuttoning the top button of his cheongsam, "When I saw you, I thought you looked like a white-collar worker, the kind of... financial industry."

An Wujiu stared at Yang Ming, his alert was obviously lowered, the corners of his mouth that had been tensed up slightly, his thin cheeks seemed to be full of these flattering remarks Runze, "It's okay, it's okay, it's not so exaggerated."

He did not deny Zhong Yirou's guess.

Aware of this, An Wujiao tilted his head in thought, but when he regained his senses, he found that the masked guy sitting directly opposite was staring at him.

Wu You, who was beside him, didn't stop playing the Rubik's Cube, and only mumbled, "Who will come to the altar if you mix well..."

Wu You sat on the left of an old man who had been silent for a long time. His white-blond hair was like haggard, and he looked at least sixty years old, but his physique was still strong. An Wujiu didn't notice him until he opened his mouth.

"There are only three and a half minutes left in five minutes, won't you talk more about games?" He has a western face, and his mouth seems to be French, but like Ueno, they can directly Hear Chinese.

The name projected in front of him is the word [Lao Yu], and there is no foreign name.

"What are you talking about?" Yang Ming's tie was crooked, and he glanced at Lao Yu, "Could it be that you want us to report all the numbers to be filled in, and then write them down after you have calculated them?"

"Is it possible?" Liu Chengwei laughed.

Yang Ming's expression was very relaxed, and he clasped his hands on the table, "Actually, this is just a warm-up game, as long as the winner is not at peace, it doesn't matter who it is. He has the advantage of the game and we are in danger."

An Wujiu was silent.

"I agree." Liu Chengwei broke his fist and suggested, "Why don't we tie this kid up and keep him from answering the questions, so that he won't get the advantage."

The noise in my head became extremely severe.

Old Yu hesitated, "Is this... not a foul?"

Zhong Yirou raised her eyebrows, "The person who committed the foul will either die, just like the guy just now, or be pushed into the punishment stack ①, you can be careful, few people can be normal come out of that hellish place. But..."

She shrugged, "If it can really eliminate a dangerous element directly, I have no problem."

These competitors are discussing their own "handling methods" recklessly.

The last sound stopped. After a moment of silence, a sharp and harsh noise made him lower his head. The next second, he heard an unreal electronic analog female voice, the content was incomplete, only intermittent a few words.

[It's too late...]

[Trust me, you will find all your memories. ]

[…must survive, come see me alive. ]

[You need company, never alone. ]

The sound came to an abrupt end, like a terminated ECG monitor, leaving only the single sound of long sleep.

Is this mother's last voice?

Where is the memory chip?

An Wujiu held his head with his hands, gasping for breath, but the voice never appeared again.

His severely injured hand had a digital imprint on the back of the hand, like the number -99.

His amnesia was indeed artificial.

Wu You saw that something was wrong with him, "What's wrong with you?"

"Leave him alone." Yang Ming sneered, "He started acting again."

He smiled and rolled up his shirt cuffs, "The game is about to start, it's a chance anyway, don't worry about it."

Really? An Wujiu raised his head.

This game is not about luck at all.

It is intelligence.

Not only does he know this, he believes Yang Ming also knows it.

Just listening to the rules, this guessing game looks like who can happen to hit the average range, but it is essentially a war of intelligence and prediction.

If the rest of his memory system is not too biased, this game is a "beauty game" model born out of economics②.

The process of choosing an average is like betting on the winner of a beauty contest. The most important thing is not whether she is really the most beautiful in her heart, but the most beautiful in most people's hearts, The bet is not the game itself, but the psychology of other contestants.

Under Zhong Yirou's flattery attack, Yang Ming did not deny his identity in the financial industry, and has always exaggerated the element of luck. The probability that he knows this theory is at least 80%.

An Wu Jiu didn't have much expression on his face, staring at the blank handwriting screen in front of him.

"The last thirty seconds, the countdown begins."

"30—"

He is very clear about his current situation. If what Yang Ming said before is true, according to his description of the previous game, it seems that he is not the type to fight alone. If this is the case, even if he can win the warm-up match and gain a certain advantage, he will become the target of public criticism in the official game. With such a serious injury, it may not last long.

“29—”

On the basis of the unknown competition system, he cannot guarantee that he will survive as a public target.

There is no benefit to being sharp.

“28—”

It can be difficult to eliminate the fears of others.

The best way is to deflect the fear.
