Chapter 552

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

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

All but the best of the bunch, Hufflepuff and Pomona used a "do nothing" approach.

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

The best strategy means that each participant chooses the best strategy, for example, the boys take a step back, instead of asking the prettiest girl, they go to the girl who is less beautiful than the prettiest girl, so that everyone has partner.

However, the reality is that the boys went crazy over Fu Rong, and no one even went to date the original school belle, the twin sisters Patil.

Sometimes people don't choose the best strategy. Boys will think, if you don't invite Fu Rong, what if I invite her? What if she agrees?

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

But he ran away without even listening to Furong's answer.

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

For Ron, inviting Hermione was a strictly dominant strategy, as long as he didn't say "you're a girl", he would almost always succeed. Both the Patil twins and Fleur are strictly underdog strategies for Ron.

When Hermione, pissed off by Ron, agreed to Victor Krum's invitation, the Patil twins became his and Harry's strictly superior choice. But the "dream pair" didn't notice it until the Patil twins were always loitering in front of them.

The girl's heart is hard to understand but also easy to understand. The two of them were originally the most beautiful, but a hibiscus came to suppress their limelight. Harry was the one all the girls wanted to ask out, but after Victor came, the girls all turned around him, but no one was fighting for the two of them. Girls are more passive than boys, and are more willing to be asked out than take the initiative to ask out. After others have been asked out one after another, most of them no longer insist on being asked out by Harry and Victor. Only Petty The Seoul twins are still holding on. They took a deep breath in their hearts, no matter what they wanted to suppress Fu Rong's limelight. As for other people's attention, they were attracted by Cedric and Zhang Qiu.

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

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

The crowd tends to follow suit, that is, when a good situation occurs, everyone's attitude will tend to be a good situation, and when a bad situation occurs, everyone's attitude will tend to be a bad situation.

Bank runs were common in the 1930s, but not every bank failed because a wise bank manager stood up and instructed everyone to withdraw only a small part of the money necessary for life; finally, after the bank run time passed, everyone found The bank survived, so the money was deposited again.

Everyone else was invited away, and I didn't want to be left behind, so I agreed. At this moment, I suddenly found that besides Harry and Victor, Cedric was also a good choice.

At this time, it is too late to regret, unless the girl refuses the boy who has already asked him out, and then goes after Cedric.

However, she wasn't sure if she could squeeze out Zhang Qiu, and she didn't want to be left behind, so she found a better partner behind her back, and the so-called "derailment" incident of "riding a donkey to find a horse" happened.

Pomona forbids this kind of situation to happen at Hufflepuff College. If she catches her or someone comes to sue, don’t go to the Christmas party after verification. People should be locked up in the dormitory.

Luckily no Hufflepuff did that, and as for the girls chasing after Victor, she didn't bother, the "beast" wasn't good enough for Pomona to be interested in chasing him, she was busy "Tackling" Severus and the people from the Ministry of Magic arranging the ball venue, there was simply no time to restrain those students.

In Nash equilibrium, the choices of participants can be changed through persuasion.

The Prisoner's Dilemma cannot change the player's choice through persuasion. Because no one is foolish enough to choose an inferior strategy.

The police arrested two suspects, A and B. The police offered them the same choice: if one person pleaded guilty and testified against the other party, while the other party remained silent, the person would be released immediately, and the other party who did not voluntarily plead guilty would 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 keep silent. However, the two cannot communicate with each other in advance, and there is no guarantee that the other party will not report themselves, which leads to a prisoner's dilemma. Starting from unilateral self-interest, if the other party remains silent, choosing to report the other party can reduce your sentence from 1 year to 0 years; if the other party reports yourself, choosing to report the other party can also reduce your sentence from 20 Years reduced to 5 years. Therefore, in any case, reporting the other party can maximize one's own interests. This has led to the only possible equilibrium of the "Prisoner's Dilemma", that is, both parties choose to report each other, and as a result, both are sentenced to 5 years in prison.

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

For example, there is a person looking at the sky on the street. Some passers-by will feel that there is something wrong with him, and some people will be curious about what he is doing, so they stop and look up together. There will be more and more people, and eventually even the whole street is looking up at the sky.

This effect is called multiple ignorance effect, and it is most obvious among strangers, mostly in cities.

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

But everyone faces a problem. They need a dance partner to participate in the Christmas dance. Bold people will choose people from different cultural backgrounds. For example, Victor chose Hermione. There are also conservative people who choose people they are familiar with. For example, Draco chooses Pansy. Like the situation where boys are crazy about Fleur. Partly because of her racial talent, mixed-race Veela is extremely attractive to human men, and another is the scarcity effect. There are not many beauties in the first place, and there are even fewer top beauties. The principle of scarcity often appears in marketing. In Chinese, it means "things are rare and expensive", "scarce things will be given higher value by us". In other words, things that are scarce are more valued and cherished. So the application of the scarcity principle goes far beyond the sales industry.

Money, power, and women are the three things that can arouse the competitiveness of men the most. When the vast majority of wealth is concentrated in the hands of a small number of people, most people will fight for a little money. In the eyes of people, it is ridiculous.

However, the poor man has a beautiful wife who doesn't care about his success or failure, and always follows him. The rich man can't maintain that kind of normality.

Because there are many people around him who deal with him for money, and he has never seen that kind of woman who marries a man only for true love, not for money.

Men will think, how can 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 no one knows that she is the kind of person who can abandon wealth and wealth for the sake of love. People have prejudices against her, thinking that she is a self-centered, arrogant, and pompous stupid girl who yells that "the food at Hogwarts is too greasy for me to wear a dress".

Ron and Harry took the Patil sisters to the ball, and they were in the limelight, but they didn't have a good time after that, although they got what everyone admired with their persistence.

The school belle actually didn't ask anyone to start the dance. Harry and Ron didn't notice the problem, how slow they must be.

The little tricks of these girls, Pomona has seen a lot, and Slytherin is much more difficult in comparison.

Ethos affects many issues. Before Harry entered the school, Severus was "wise". Every year, the champion of the House Cup and Quidditch is Slytherin. He has super personal abilities, whether it is 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 wands cannot be used outside the school. Although the little snakes would whisper, they still obeyed. After Harry entered the school, the house cup and the Quidditch cup were gone. The basilisk incident in the second school year reminded these pure-blood children Another "leader" Voldemort, compared with the fear of others, they think of the glory of the reign of pure blood and the fear of others, "respect" is very important to Slytherin, and they enjoy being feared a feeling of.

In the third school year, Remus's joke made Severus lose face. If a "snake king" is not respected, then he is not far from stepping down. In the fourth year, Moody publicly humiliated Draco Malfoy. Severus, the godfather, did not avenge him, and his authority was lost.

In the fifth year of school, Umbridge made a mess in the school, and it was not published in the newspapers. Others, especially the old subordinates of Voldemort, knew that he was back. Severus' prestige was even lower. As for the matter, he has lost his leadership, and Draco has followed Umbridge.

At this time, no one listened to Severus who said that magic was not allowed outside the school. Pure-blood families had a lot of ways to get rid of traces of surveillance. Since the sixth year, Slytherin has not listened to the orders of his headmaster.

Game theory can be applied in many ways, not just 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 intervene in the economy. During the Great Depression, his actions were for re-election and to please the big farmers and capitalists.

Albus was squeezing Severus' influence at will.

If it weren't for Albus, all of Severus' achievements would not be possible, just like a father has the power to dispose of his children at will, including abandonment.

Let the foundling and the beloved share the same room, Albus uses power to suppress Severus to teach Harry Occlumency, this is the principal's power, and this school is his "kingdom".

Most people 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 they catch up with Hibiscus, they are the “winners”. They can make money by speculating in real estate and stocks. Having the "American Dream" is 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 that little person struggling at the bottom of society and worrying about food and clothing. You are a middle-class person.

What a cute and innocent idea.

Do you have a loan? If there is a "leek" waiting to be harvested in the bubble economy, it is not as good as the farmer who is self-sufficient in the countryside and has no debts. At least he doesn't have to worry about being laid off at any time, and he doesn't have to agree to unreasonable demands from his boss.

Albus is not a kind grandfather, but Pomona has always been "obedient", and her life has been arranged very 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 it off, and you don't need to deliberately hide yourself anymore.

Albus kept that secret so deep, it was really depressing for him.

But who told him that he likes the same sex, and that person is Gellert Grindelwald. She guessed all the women and didn't guess that it was him. It was really unexpected.
