Chapter 552 "Switch"

Lao Tzu believes that "I do nothing, and the people become themselves; I like to be quiet, and the people are upright; I do nothing, and the people become rich; I have no desires, and the people are simple."

"Governing by doing nothing" does not mean doing nothing, but not interfering too much and giving full play to the creativity of ordinary people.

Except for the best ones, Pomona and other Hufflepuffs use the method of "treating by doing nothing".

In a Nash equilibrium, a strategy combination is a set that includes a self-selected strategy for each player.

The best strategy means that each participant chooses the best strategy. For example, the boys take a step back and do not invite the most beautiful girl, but instead date a girl who is less beautiful than the most beautiful girl. This way everyone has something.

Dance partner.

However, the reality is that the boys went crazy for Fleur, and even the original school beauties, the Petil twins, no one wanted to date.

Sometimes people don't choose the optimal strategy. Boys will think, if you don't invite Fleur, what if I invite her and she agrees?

Most people are obsessed with small-probability events and want to try their "luck", so Ron loudly invited Fleur in the corridor.

But he didn't even listen to Furong's answer and ran away.

The so-called strictly advantageous strategy means that no matter what strategy the opponent adopts, this strategy is always better than any other strategy. The strictly disadvantaged strategy refers to other strategies other than the strictly advantageous strategy.

For Ron, inviting Hermione is his strict advantage strategy. As long as he doesn't say "you are a girl", he will basically succeed. The Patil twins and Fleur are both Ron's strict disadvantage strategies.

When Hermione was so angry with Ron that she agreed to Victor Krum's invitation, the Patil twins became the strictly superior choice for him and Harry. But the "dream pair" didn't realize that.

The Patil twins always dangled in front of them before they noticed.

Girls' hearts are hard to understand but easy to understand. The two of them were originally the most beautiful, but then Fleur came and suppressed their limelight. Harry was the one that all the girls wanted to invite, but after Victor came, the girls

They all circled around him, but no one tried to compete with them. Girls were more passive than boys, and were more willing to be asked out than to take the initiative. After other people were asked out one after another, most of them stopped.

Only the Patil twins continued to insist on being asked out by Harry and Victor. They were holding their breath and wanted to overwhelm Fleur's limelight no matter what. As for the other people's attention, they were blocked.

Derek and Zhang Qiu were attracted away.

Cedric was also the prince of the school, at least he was much better than the "ordinary people" who dated him, so Zhang Qiu's ceremonial robe was hidden.

This strategy is not strictly a dominant strategy, but jealousy makes people make irrational choices.

There is a phenomenon of people following the trend, that is, when a good situation occurs, everyone's attitude will tend to the good situation, and when a bad situation occurs, everyone's attitude will tend to the bad situation.

Bank runs often occurred in the 1930s, but not every bank failed, because wise bank managers stood up and directed everyone to withdraw only a small part of the money necessary for life; in the end, after the bank run time passed, everyone discovered that

The bank did not fail, so I deposited the money again.

Everyone else had been asked out, and he didn't want to be left behind, so he agreed. Then he suddenly discovered that in addition to Harry and Victor, Cedric was also a good choice.

It's too late to regret at this time, unless the girl rejects the boy who has already dated him and pursues Cedric again.

However, she was not sure whether she could squeeze out Zhang Qiu, and she didn't want to be left behind, so she went behind her back to find a better partner. The so-called "cheating" incident of "riding a donkey to find a horse" happened.

Pomona prohibits this situation from happening at Hufflepuff Academy. If she is caught, or someone comes to complain, she will not go to the Christmas party after verification. No matter how beautiful the dress and dancing shoes the girl has prepared, she will be alone.

Let's keep people in confinement in their dormitories.

Fortunately, no Hufflepuff did this. As for the girls chasing Victor, she was too lazy to care. The "beast" was not good enough to make Pomona interested in chasing. She was busy at the time.

"Dealing" Severus and the people from the Ministry of Magic arranged the dance venue, and they didn't have much time to control the students.

Nash equilibrium can change the choices of participants through persuasion.

In the Prisoner's Dilemma, the participants' choices cannot be changed through persuasion, because no one is stupid enough to choose an inferior strategy.

The police arrested two suspects A and B. The police offered the two suspects the same choice: if one confesses and testifies against the other, and the other remains silent, the person will be released immediately, and the other who does not plead guilty will be sentenced to 20 years in prison;

If both remain silent, both will be sentenced to 1 year in prison; if both report each other, both will be sentenced to 5 years in prison.

From the perspective of the common interests of both parties, it is the best choice for both of them to remain silent. However, if the two cannot communicate with each other in advance, there is no guarantee that the other party will not report them, which leads to a prisoner's dilemma. From the perspective of unilateral self-interest, in

If the other party remains silent, choosing to report the other party can reduce one's sentence from 1 year to 0 years; if the other party reports oneself, choosing to report the other party can also reduce one's sentence from 20 years to 5 years. So no matter

In any case, reporting the other party can be an advantageous strategy that maximizes one's own interests. This leads to the only possible equilibrium in the "Prisoner's Dilemma", which is that both parties choose to report the other party, and the result is that both of them are sentenced to 5

Year.

Many people actually fall into a prisoner's dilemma without knowing it. Generally speaking, when people lack confidence in themselves, when the situation is not very clear, and when uncertainty prevails, people are most likely to accept and refer to the behavior of others.

For example, if there is a person looking up at the sky on the street, some people passing by will think something is wrong, and some will be curious about what he is doing, so they will stop and look up together. When there are five or six people on the street looking up like this, they will look up at the sky.

There will be more and more people, and eventually even the whole street will be looking up at the sky.

This effect is called the pluralistic ignorance effect, which is most pronounced among strangers and mostly occurs in cities.

There are not many students in Hogwarts, about 1,000, but many of them still don't know each other, especially boys and girls. He knows her name, figure, and appearance, but he doesn't know her personality and thoughts. In addition, Boys and girls from other schools form a multicultural collection.

But everyone faces a problem, they need dance partners for Christmas dances. Bold people will choose people with different cultural backgrounds, such as Victor, who chose Hermione, while some conservative people will choose people they are familiar with, such as Della. Co chose Pansy. The reason why boys are crazy about Fleur may be partly because of her racial talent. Mixed-blood Veela has a strong attraction to human men. Another reason is the scarcity effect. There are not many beauties in the first place. Top beauties Less. The principle of scarcity often appears in marketing. In Chinese, it means "things are rare and valuable" and "scarce things will be given higher value by us". In other words, scarce things make people more valuable. Value and cherish. Therefore, the application of the scarcity principle goes far beyond the sales industry.

Money, power, and women are the three things that most arouse men's competitive spirit. When the vast majority of wealth is concentrated in the hands of a few people, most people will fight to death for a little money. This is true for those who have money. It's funny to people.

However, a poor man has a beautiful wife who follows him all the time and doesn't care about his success or failure. A rich man cannot maintain that kind of normalcy.

Because there are many people around him who deal with him for money. He has never seen the kind of woman who doesn't care about money and only marries a man for true love.

Men would think, how could such a woman exist? Fleur is, she married Bill Weasley, a poor man who was scratched and disfigured by a werewolf.

This quality alone is already very valuable, plus she is very beautiful. Love and war can make people lose their minds. But before getting to know Furong deeply, no one knows that she is the kind of person who can abandon glory and wealth for love. Most people People are prejudiced against her, thinking that she is a self-centered, arrogant, stupid girl who is vain and shouts, "The food at Hogwarts is so greasy that I can't wear a dress."

Ron and Harry took the Patil sisters to the dance, and they were in the limelight, but the rest of their time was not pleasant, although they got something that everyone admired through their persistence.

The school beauty actually had no one to ask for when the dance was about to start. Harry and Ron didn't realize the problem. They must be so slow.

Pomona has seen a lot of these little girls' tricks, but it's much more difficult for Slytherin.

The atmosphere affects many problems. Before Harry entered the school, Severus was "wise". Slytherin won the Academy Cup and Quidditch match every year. His personal ability was super strong, whether it was potions or magic. He also blatantly stated that he likes black magic and was a Death Eater before. Who is cooler than him?

He said that the wand could not be used outside the school. Although the little snakes could whisper, they still obeyed. After Harry entered the school, the Academy Cup and the Quidditch Cup were gone. The basilisk incident in the second year reminded the children of these pure-blood families.

Another "leader" Voldemort, compared with the fear of others, they think of the glory of the pure-blood reign and the fear of others. "Respect" is very important to Slytherin, and they enjoy being feared by others.

a feeling of.

In the third year, Remus's joke made Severus lose face. If a "snake king" cannot be respected, then he is not far from stepping down. In the fourth year, Moody publicly humiliated Draco Malfoy and was personally

Severus, the godfather, did not avenge him, and his authority was completely lost.

In the fifth year, Umbridge created a mess in the school, which was not published in the newspapers. Others, especially Voldemort's old subordinates, knew that he was back. Severus' prestige was even lower, and with the Wolfsbane potion

He had lost his ability to lead, and Draco followed Umbridge.

At this time, no one would listen to Severus's words about not using magic outside the school. Pure-blood families had many ways to escape surveillance. Starting from the sixth year, Slytherin no longer listened to his orders as the headmaster.

Game theory can be applied in many aspects, not just economics and finance.

The market has spontaneity and blindness, and people also have spontaneity and blindness. Hoover believed too much in the spontaneity of the market and did not interfere in the economy. During the Great Depression, his actions were to get re-elected and to please the large farmers and capitalists.

Albus, on the other hand, exploited Severus' influence at will.

If it weren't for Albus, all of Severus' achievements would not have been possible, just like a father who has the power to do whatever he wants with his children, including abandonment.

Putting the outcast and the beloved in the same room, Albus used his power to suppress Severus and had to teach Harry Occlumency. This is the power of the headmaster, and this school is his "kingdom".

Most people themselves don't know whether what they are doing is right or wrong. They just follow the trend. Human beings need a sense of identity in social activities. If you catch Furong, you will be a "winner". If you make money by speculating in real estate and stocks, you will realize

If you have the "American Dream", you are a "winner in life". If you have a good car, it will be even more perfect.

You are different from the past. You are no longer the little person struggling at the bottom of society and worrying about food and clothing. You are now middle class.

What a cute and innocent idea.

Are there loans? If there are, they are just "leeks" waiting to be harvested in the bubble economy. They are not as good as the self-sufficient, debt-free farmer in the countryside. At least he doesn't have to worry about being laid off at any time, nor does he have to agree to the boss's unreasonable demands.

Albus is not a kind grandfather, but Pomona has always been "obedient", and her life has been arranged well by Albus, just like Rose, until "Jack" appeared.

Her "Jack" told her: You can admit that you like the feeling of being noticed, but you can choose not to show off, and you no longer need to deliberately hide yourself.

Albus hid that secret so deeply, he was really depressed.

But who told him that he liked someone of the same sex, and that person was Gellert Grindelwald. She had guessed all the women and still hadn't guessed that it was him. It was really unexpected.
