Chapter 552 "Switch"

   Lao Tzu believes that "I do nothing, but the people are self-contained; I am quiet, but the people are upright; I have nothing, but the people are rich; I have no desires, but the people are simple."

  "Governing by doing nothing" is not doing nothing, but not intervening too much to give full play to the creativity of ordinary people.

  Except for the best ones, Hefpaff's other people, Pomona, use the "doing nothing" approach.

  In the Nash equilibrium, the strategy combination is a set that includes a strategy chosen by each participant.

The best strategy means that each participant chooses the best strategy. For example, boys take a step back and don’t invite the most beautiful girl, but instead invite a girl who is less than the most beautiful girl, so that everyone has it. The dance partner.

  However, the reality is that the boys went crazy for Furong, and even the original school girl Pettil twins and sisters did not go to the appointment.

  Sometimes people will not choose the best strategy. The boys will think, if you don’t invite Furong, I will invite her if she agrees?

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

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

  The so-called strict advantage strategy means that no matter what strategy the opponent adopts, the strategy adopted is better than any other strategy. The strict disadvantage strategy refers to other strategies than the strict advantage 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 Pettil twins and Fleur are both Ron's strictly disadvantaged strategies.

  When Hermione was **** off by Ron and agreed to Victor Klum’s invitation, the Pettil twins became a strict superior choice for him and Harry. But the "dream combination" didn't notice it, and only noticed when the Pettil twins were always in front of them.

  The girl’s heart is hard to understand and easy to understand. The two of them were originally the most beautiful, but a hibiscus came to suppress their limelight. Harry was the one that all the girls wanted to invite, but after Victor came, the girls turned around him, but no one quarreled between them. Compared with boys, girls are more passive and prefer to be asked rather than actively. After others are asked to leave, most people no longer insist on being asked by Harry and Victor, only Petty The twins are still insisting. They sighed in their hearts, and no matter what, they wanted to suppress the limelight of Furong. As for the attention of others, Cedric and Zhang Qiu were drawn away.

  Cedric is also the prince of the school, at least he is much better than his own "ordinary person", so Zhang Qiu's robe was hidden.

  This strategy is not a strict advantage strategy, but jealousy makes people make irrational choices.

  There is a phenomenon that the crowd follows the trend, that is, when a good situation occurs, everyone's attitude tends to a good situation, and when a bad situation occurs, everyone's attitude tends to a bad situation.

Bank runs often happened in the 1930s, but not every bank went bankrupt, because a wise bank manager stepped up to instruct everyone to take out only a small part of the money necessary for life; finally, after the bank run time passed, everyone found out The bank did not go bankrupt, so the money was deposited again.

  The other people were asked to leave, and I didn’t want to be left, so I agreed. At this moment, I suddenly found out that Cedric was also a good choice besides Harry and Victor.

  At this time, it’s too late to regret, unless the girl refuses to ask the boy who has dated him, and then chase Cedric.

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

This situation is forbidden to happen to Pomona at Hefpaff College. If you are caught by her or someone comes to complain, don’t go to the Christmas party after verification. No matter how beautiful the girl’s dress and dancing shoes are, she can do it herself. People are confined in the dormitory.

Fortunately, no Hefpaff did this. As for the girls running after Victor, she didn’t bother to care. The "beast" was not good enough to make Pomona interested in chasing. She was busy at the time. "Handling" Severus and the people from the Ministry of Magic set up the ball venue, and didn't have so much time to control the students.

  Nash equilibrium can change the choices of participants through persuasion.

  The prisoner’s dilemma cannot be changed through persuasion. Because no one is stupid enough to choose a disadvantaged strategy.

The police arrested two suspects A and B, and the police offered them the same choice: if one person pleads guilty and testifies against the other person, but the other person remains silent, the person will be released immediately, and the other party who does not voluntarily pleaded guilty will be sentenced to 20 years in prison; If both of them remain silent, both will be sentenced to 1 year in prison; if they 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 to remain silent. However, the two cannot communicate with each other in advance, and there is no guarantee that the other will not report themselves, which leads to a prisoner’s dilemma. Proceeding from unilateral self-interest, choosing to report the other party can reduce his sentence from 1 year to 0 years when the other party remains silent; in the case of the other party reporting himself, choosing to report the other party can also reduce his sentence from 20 years. The year is reduced to 5 years. Therefore, no matter what the situation is, it is an advantageous strategy to inform the other party to maximize one's own interests. This leads to the only possible equilibrium in the "Prisoner's Dilemma", that is, both sides choose to report each other, and the result is that both of them are sentenced to 5 years in prison.

  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 other people's behavior.

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

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

Hogwarts has a small number of students, about 1,000, but many people still don’t know each other, especially boys and girls. He knows her name, figure, and looks, but doesn’t know her character and thoughts, plus Boys and girls from other schools have formed a multicultural collection.

  But everyone is facing a problem. You need a partner to participate in the dance party at Christmas. Courageous people will choose people from different cultural backgrounds. For example, Victor chooses Hermione, and some conservative ones choose people who are familiar with him. For example, Draco chooses Pansy, like boys crazy for Fleur. Part of it is because of her racial talents. The mixed-race Veela has a strong attraction to human males. Another is the scarcity effect. There are not many beautiful women, and there are fewer top beauties. The principle of scarcity is often seen in marketing. In Chinese, it means "things are precious", "the things that are scarce will be given higher value by us". In other words, things that are scarce are more valued and cherished. Therefore, the application of the scarcity principle goes far beyond the sales industry.

Money, power, and women, these three things can most arouse male competition. When the vast majority of wealth is concentrated in the hands of a small number of people, most people will fight for a little bit of money. It's ridiculous in human eyes.

  However, the poor ghost has a beautiful wife who does not care about his success and failure, and has been following his beautiful wife. The rich can no longer maintain that ordinary heart.

  Because there are so many people around him who deal with him for money, he has never seen a woman who doesn't spend money but marries a man just for true love.

  Men think, how could there be such a woman? Furong is, she married Bill Weasley, a poor ghost who was scratched and disfigured by a werewolf.

This quality alone is already very precious, plus she is very beautiful, love and war can make people lose their minds, but no one knows that she is the kind of person who can abandon glory and wealth for love, most of them People have prejudices against her, thinking that she is a self-centered, arrogant, and will yell "The food at Hogwarts is too greasy, which prevents me from wearing a dress."

  Ron and Harry took sisters Pettil to the prom. They were in the limelight, but they had an unpleasant time afterwards, although they got something that everyone admired with their persistence.

  The school flower actually arrived at the prom and there was no appointment at the beginning of the party. Neither Harry nor Ron realized the problem, how slow they should be.

  These girls' tricks and careful Spomona have watched a lot, compared with Slytherin.

Atmosphere affects many problems. Before Harry entered the school, Severus was "wise." Slytherin was the champion of the Academy Cup and Quidditch every year. His personal ability was superb, whether it was potions or magic. He also blatantly stated that he likes black magic and was a Death Eater before. Which Dean is cooler than him?

He said that magic wands could not be used outside the school. Although the little snakes would whisper, they still obeyed. After Harry entered school, the Academy Cup and Quidditch Cup were gone. The basilisk incident reminded these pure-blooded children in the second year. 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 the fear of being feared. a feeling of.

Severus’s face was discredited by Remus’ jokes in the third year. If a "snake king" is not respected, then he is not far from stepping down. In the fourth year, Moody's publicly humiliated Draco Malfoy. Severus, who had been for the godfather, did not avenge him, and his authority was lost.

In the fifth year of school, Umbridge got a mess in the school, and it was not published in the newspapers. Others, especially Voldemort’s old men in the past, knew that he was back. Severus’s prestige was even lower, and the wolf poison potion was added. He had lost his leadership, and Draco followed Umbridge.

  At this time, Severus said that no magic was allowed outside the school, and no one listened. Some of the pure-blood families were able to get rid of traces of surveillance. Since the sixth year of school, Slytherin has not listened to his dean’s orders.

  Game theory can be applied in many ways, not just economics.

  The market has spontaneity and blindness, and people also have spontaneity and blindness. Hoover believed excessively in the spontaneity of the market and did not intervene in the economy. During the Great Depression, his actions were for re-election and to please large farmers and capitalists.

  Albus squeezed Severus' influence at will.

  If it were not for Albus, all of Severus’s achievements would have been impossible, just as the father had the right to dispose of the child at will, including desertion.

  Let the outcast and the darling live in the same room. Albus used his power to suppress Severus and must teach Harry Occlumency. This is the power of the principal, and this school is his "kingdom".

Most people themselves don’t know if what they’re doing is right or wrong. They just follow the trend. Human beings need a sense of identity in social activities. After chasing Furong, they are the “winner”. Real estate and stocks are speculating in real estate and stocks to make money. The "American Dream" is the "winner of life." If there is another good car, it will be even more perfect.

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

  What a cute and innocent idea.

  Are there loans? If there are "leeks" waiting to be harvested in the bubble economy, it is 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, and he doesn't have to agree to the boss's unreasonable request.

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

  Her "Jack" told her: You can admit that you like to be noticed, but you can choose not to show off, you don't need to deliberately hide yourself anymore.

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

  But who told him that he likes the same sex, and that person is Gellert Grindelwald. She guessed all the women but never guessed that it was him. It was really unexpected.
