What is a realistic example of the prisoner s dilemma

Let's start by explaining what the prisoner's dilemma is.

The "Prisoner's Dilemma" was developed in 1950 by Merrill Flood and Melvin Dresher of the RAND Corporation in the United States, and was later elaborated by the consultant Albert Tucker in a prisoner's manner and named "The Prisoner's Dilemma".

The Prisoner's Dilemma (Prisoner'sdilemma): A peculiar game between two ** prisoners that illustrates why it is difficult to maintain cooperation even when it is beneficial for both parties. The prisoner's dilemma is a representative example of a non-zero-sum game in game theory, reflecting that the best choice of the individual is not the best choice of the group.

It is only a model in nature, but similar situations will occur in reality, such as competition, environmental protection, and interpersonal relations.

Here's an example. A and B are caught, and if A confesses and accomplice B remains silent, then A is not guilty, but B is sentenced to five years. If, on the other hand, A is silent, but B confesses, then again, B is free, and A is to be imprisoned for five years.

AB Both confessed and pleaded guilty, and each of them was sentenced to three years in prison. But if they are all silent, they will be sentenced to two years each.

The best example in reality is the arms race between the United States and the Soviet Union, which is actually a kind of prisoner's dilemma, the arms race between the United States and the Soviet Union during the Cold War was their own advantageous strategy, and neither side could trust the other side not to engage in military development, and both were worried that they would be in danger by design, so even if there was a "covenant", in the end this covenant had to be torn up.

Although the dilemma itself is only model-based, and the rational choices made by individuals often lead to collective irrationality, similar situations often occur in reality. Understanding the prisoner's plight is of some practical significance.

Use easy-to-understand language and stories around us to explain the psychological knowledge we have to know in our lives, and today explain the origin and specific meaning of the prisoner's dilemma.

As follows:

1. For example, perfume, no matter how many adjectives you use to describe your perfume, buyers can't tell what it smells like. That's why perfume brands like to offer samples in magazines. Of course, as long as you buy the perfume, you can still know its taste right away.

There are also some products that you buy back and use, and it is still difficult to make an evaluation.

2. For example, it is difficult for buyers to evaluate its effect in advance no matter what, and it will take a long time to make an evaluation after buying back. Others, such as those with durability as their main selling point, have the same problem. So "invalid refund", "extend the shelf life."

and other promises, which can be a signal from the seller.

Introduce. The Prisoner's Dilemma.

It's a game theory.

It has practical significance for sellers. Tmall, JD.com, Amazon.

Feng Shui takes turns, and the rules of the game often change. With the flow and changes of the e-commerce environment, many "dry goods" quickly become useless.

But there is also some theoretical knowledge, no matter how China's e-commerce changes, it will always shine and always bring you new insights and inspiration. Such theories and knowledge should be studied carefully.

The Prisoner's Dilemma This time the house was divided, and the villagers' performance was a typical prisoner's dilemma. It's a pity that my thinking and expression skills are very poor, and I can't straighten out the logical relationships. If you can't think clearly, you can't talk about others clearly.

I just vaguely feel that I am right, the best policy is that all the villagers do not choose a house, so that ** can change the unreasonable policy. But in fact, human nature is selfish, in order to choose a house early, the logic is the prisoner's dilemma, I don't choose, others will choose, just like two prisoners, if I don't expose it, then the other party will expose it. It's better for me to expose it first.

Logically speaking, I don't need to participate in the game with **, because there are very few interests involved in me, but my purpose in the beginning is to observe and learn. It's interesting to see who is smart, who speaks, and how decisions are made in reality.

The impact of the environment on people.

The environment has a huge impact on people's lives, and it is also invisible. Most people don't realize that. That's how I felt when I met some of the people in the Tin House yesterday.

The tin house was built in the village to accommodate the elderly who could not afford to rent a house, but I was fortunate not to live in it. I know that there are two people who are about the same age as me who have threatened the cadres to move in, one has died of drunkenness, and the other I saw him yesterday and listened to him, and I think this person is basically finished. Tin house, what I see every day is a bad environment, hundreds of old men and women waiting to die, how can they have a positive attitude towards life?

When I talk about the impact of the environment on people, I think that I can say that I have spent most of my life and energy gambling, and I really don't achieve anything in my career, but the people around me are like that. How hard it is to change.

I've always felt that human willpower is limited, and it's hard to change the environment. So it's better to choose the environment and let the environment change itself.
