What is Murphy's Law?

Murphy's Law: If there are two or more ways to do something, and one of them will lead to disaster, then someone will always make this choice. The basic content is: if things are likely to go bad, no matter how unlikely it is, it will always happen.

Murphy's law is a kind of psychological effect, which was put forward by Edward A. Murphy, also known as Murphy's law and Murphy's theorem.

There are four main contents of Murphy's law: first, nothing is as simple as it seems; Second, everything will take longer than you expected; Third, things that can go wrong will always go wrong; Fourth, if you are worried about something happening, it is more likely to happen.

1, the source of Murphy's law

In 1949, an engineer named eddie murphy, an air force captain, played a casual joke on one of his unfortunate colleagues: "If something is likely to be done badly, it will be even worse if he is allowed to do it."

At first, a harmless joke didn't mean anything, just said the helplessness brought by bad luck. Perhaps because there are too many unfortunate people in this world, or because people always make such mistakes, this sentence spread quickly and was finally interpreted as: if bad things are possible, no matter how unlikely, they will always happen and cause the greatest possible loss.

2. The reference significance of Murphy's law.

To break the "curse" of Murphy's Law, we must have firm self-confidence, stable mentality, positive psychological hints, express them in positive language, adopt a zero-tolerance strategy for negative emotions or bad thoughts such as inferiority, and disperse them as soon as they are detected. Even if you encounter setbacks, you should have the consciousness of "doing your best and resigned to fate", give full play to your potential, respond bravely, and always face life with a positive and sunny attitude.

What is Murphy's Law?

Murphy's law is a kind of psychological effect, which was put forward by Edward A. Murphy, also known as Murphy's law and Murphy's theorem.

The original words of Murphy's law are: if there are two or more ways to do something, and one of them will lead to disaster, then someone will make this choice. The basic content is: if things are likely to go bad, no matter how unlikely it is, it will always happen.

I. Production conditions

In mathematical statistics, there is an important statistical law: suppose that the probability of an accident in an experiment (activity) is p (p >; 0), the probability of appearing at least once in n experiments (activities) is p = 1-(1-p) n. It can be seen that no matter how small the probability p is (i.e. small probability events), when n is getting bigger and bigger, p is getting closer and closer to1.

This conclusion was applied to safety management in eddie murphy. He pointed out: if there is a wrong way to do anything objectively, or there is a possibility of an accident, no matter how small the possibility is, there will always be an accident at some point when doing it repeatedly. In other words, as long as the possibility of an accident exists, no matter how small it is, it will happen sooner or later.

Second, the specific content

1. Nothing is as simple as it looks.

Everything will take longer than you expected.

3. Things that may go wrong will always go wrong.

If you are worried about something happening, it is more likely to happen.

The fundamental content of Murphy's Law is that "everything that can go wrong has a high probability of going wrong", that is to say, as long as any event has a probability greater than zero, it cannot be assumed that it will not happen.

Murphy's law is a psychological effect, which was put forward by Edward A. Murphy.

Main contents: First, nothing is as simple as it seems; Second, everything will take longer than you expected; Third, things that can go wrong will always go wrong; If you are worried about something happening, it is more likely to happen. The original words of Murphy's law are as follows: If there are two or more ways to do something, and one of them will lead to disaster, then someone will definitely make this choice.

Extended data:

Murphy's law comes from Edward A. Murphy, a captain engineer at Edwards Air Force Base in the United States. 1949, he and his boss, Major stapp, participated in the deceleration overweight experiment of MX98 1 rocket conducted by the US Air Force.

The purpose of this experiment is to determine the tolerance limit of human beings to acceleration. One of the experimental projects is to hang the 16 rocket accelerometer above the subject. At that time, there were two ways to fix the accelerometer on the bracket, but incredibly, someone methodically installed all the 16 accelerometers in the wrong position.

So Murphy made this famous conclusion that if there are many ways to do a job, and one of them will lead to an accident, then someone will do it in this way. References:

What are the contents of Murphy's theorem?

What is Murphy's Law? The simplest expression is that the more afraid of an accident, the more afraid of an accident. Anything that can go wrong will go wrong. The original sentence of this law is this: if there are two or more ways to do something, and one of them will lead to disaster, then someone will do it. If there are two or more choices, one of which will lead to disaster, someone will make this choice. Murphy's Law tells us that things tend to develop in the direction you think is bad, as long as there is such a possibility. For example, you have two keys in your pocket, one for your room and the other for your car. What if you want to take out your car keys now? Yes, you often take out your room key. Murphy's law is widely used, revealing a unique social and natural phenomenon. Its extreme expression is that if a bad thing is possible, no matter how small the possibility is, it will always happen and cause the greatest possible harm. This law is recorded in detail in the ancient oriental enigma Yihua: all living things, including people, are bound by all kinds of things. The existence of bondage is one of the laws of nature. People have to face the shackles of "time". The body is a container for the soul, and it also binds the soul. People can't get rid of shackles. Many shackles are unique to all living things, not people. There is only one kind of shackles in the world that are unique to people, and this kind of shackles is very powerful. Language is the most terrible and powerful shackle unique to people. Once people say it, they can't take it back. What you said doesn't happen. If you are worried that something bad may happen, then such a bad thing will happen. Therefore, the ancients thought that women should wear bracelets of clouds of clouds and men should wear ornaments of red bamboo, and added "hooves and hooves, dream windows and sparse stones, Danbo in northern Hebei" to the binder, thus transferring Wang Fu.

Extended data

Murphy's law reminds us that fallibility is the inherent weakness of human beings. No matter how advanced the technology is, accidents will happen. Moreover, the clearer the means to solve the problem, the more serious the trouble we face. In the face of human's own defects, we'd better consider it more thoughtful and comprehensive, and take various insurance measures to prevent disasters and losses caused by unexpected human errors.

In the final analysis, "mistakes" are as much a part of the world as we are. Arrogance will only make us ask for it. We must learn how to accept mistakes and learn from them. Murphy's law is not complicated and profound.

The key point is that it reveals the scientific truth that people can't ignore small probability events in safety management; It reveals that safety management must play a warning role and adhere to the significance of prevention first. At the same time, it is of great practical significance to educate people about safety and improve the level of safety management.

What is Murphy's Law?

Edward A. Murphy is a captain engineer at Edwards Air Force Base in the United States. He participated in 1949 MX98 1 experiment conducted by the United States Air Force. The purpose of this experiment is to determine the tolerance limit of human beings to acceleration. One of the experimental projects is to hang the 16 rocket accelerometer above the subject. At that time, there were two ways to fix the accelerometer on the bracket, but incredibly, someone methodically installed all the 16 accelerometers in the wrong position. So Murphy made this famous assertion, which was quoted by the subject at the press conference a few days later.

To put it another way: suppose you drop a piece of dry bread on the carpet, both sides of the bread may touch the ground. But suppose you drop a piece of bread on the carpet with a layer of jam on one side, usually the side with jam. At the press conference afterwards, stapp called it "Murphy's Law" and repeated it in a very concise way: everything that can go wrong will definitely go wrong. Murphy's law spreads like wildfire in the field of technology, because it tells an ironclad fact: technical risk can change from possibility to sudden fact.

A few months later, this "Murphy's theorem" was widely cited in the related fields of aerospace machinery. After many years, this "theorem" has gradually entered the category of idioms, and its connotation has been endowed with infinite creativity, and many variants have appeared, among which the most famous one is also called Finagle law, and its specific content is: if anything can go wrong, it will go wrong. (it will make mistakes, and it will eventually make mistakes. This law is considered to be the best imitation and elaboration of Murphy's theorem.

What is the meaning of Murphy's law?

Murphy's law tells us that making mistakes is an inherent weakness of human beings. No matter how advanced the technology is, accidents will happen.

Moreover, the clearer the means to solve the problem, the more serious the trouble we face. Therefore, we should be as considerate as possible in advance. If misfortune or loss really happens, we should respond with a smile. The key is to sum up the mistakes made, not to try to cover them up.

In 2003, when the space shuttle Columbia was about to return to the ground, it disintegrated over central Texas, killing all six American astronauts on board and Ramon, the first Israeli astronaut to go into space. The crash of the space shuttle Columbia also confirmed Murphy's law.

It is reasonable that something will happen to such a complicated system, either today or tomorrow. After an accident, people should always actively look for the cause of the accident to prevent the next accident, which is understandable by people's general reason. Otherwise, it is unacceptable for a country to give up the space industry or let the next accident happen again.

Man can never be God. When you are arrogant, Murphy's Law will let you know how powerful it is. On the contrary, if you admit your ignorance, Murphy's Law will help you do it more strictly. This is actually that probability is at work, and people are not as good as the sky. As the old saying goes, "Nothing is difficult in the world, and nothing is impossible to a willing mind."

And "it never rains but it pours". For example, if you don't win the lottery in several issues, you will definitely win the million-dollar prize in the end. Although the probability of disaster is very small, it will break out from the weakest link when it accumulates to a certain extent.

Therefore, the key is to clean up the dead angle at ordinary times, eliminate unsafe hidden dangers and reduce the accident probability. Bring what you're afraid of. A good state is to only think about the technical essentials and forget yourself.

Murphy's theorem states as follows: "If a thing is likely to develop in a bad direction, it will certainly develop in the worst direction". For example, you have two keys in your pocket, one for your room and the other for your car. What if you want to take out your car keys now? Yes, you often take out your room key.

Murphy's Law, perkinson's Theorem and Peter's Principle are called the three most outstanding discoveries in western culture in the 20th century. Murphy's law is not a probability law that emphasizes human error, but an accidental inevitability. Let's take another example: you have a gold coin in your pocket, so you will touch your pocket every once in a while to see if it is still there, so your routine actions attract the attention of thieves and eventually they steal it.

Even if it wasn't stolen by a thief, the pocket you've been groping around for was finally worn out, and the gold coin fell out and lost. This explains why the more you are afraid of what will happen, the more it will happen. Why? It's only because I'm afraid that I care. The more you concentrate, the more likely you are to make mistakes.

What is Murphy's theorem?

One of Murphy's laws, Murphy's law, perkinson's theorem and Peter's principle, is called the three most outstanding discoveries of western culture in the 20th century.

It originated in 1949, when an engineer named Murphy, a captain of the US Air Force, found that if you dropped a piece of dry bread on the carpet, both sides of the bread might hit the ground. But suppose you drop a piece of bread coated with jam on one side on the carpet, and it is often the side coated with jam that falls on the carpet (trouble).

In other words: if something is likely to go bad, this possibility will become a reality. This is Murphy's law.

It has a wide range of applications and reveals a unique social and natural phenomenon. Its extreme expression is that if a bad thing is possible, no matter how small the possibility is, it will always happen and cause the greatest possible harm.

Second, 1. If you want to know in advance which trades are likely to lose money, Murphy's Law can tell you: 1) those trades that have not established protective stop loss orders; 2) Careless holding too many positions; 2. The application of Murphy's law in the stock market: you are afraid of falling, but it will fall for you; You expect to go up, but you can't go up; You can't help selling it, it has already started to rise; You watch five stocks and buy one of them. As a result, except for this one in your hand, all the other four stocks rose very well.

3. Q: I am optimistic about three stocks and buy one of them. As a result, except this one in my hand, everything else went up very well. What should I do? My experience is: among several stocks that are optimistic at the same time, buy the most uncertain one. Or the last few stocks in your mind may work best.

The thing with the highest expectation in the stock market is also the most disappointing. Third, if the water, the later brother said: 1. The place where you found the lost thing is the last place you looked for.

2. If it rose for five trading days in the first three days, you didn't pay attention; After two days, it collapsed. Look: Murphy's law works! 3. The banker's beheading is something that many people didn't expect.

If you put the stock in the bank, you can't help thinking that it will jump up one day. Since it is possible, there is a chance to realize it.

Bankers were comfortable for several years, and we didn't pay attention. One day we went diving. Look: Murphy's Law is working again. 4. So: This is also a probability.

Good and bad results happen every day, and the possibility of both exists at the same time. Good grades, no one noticed.

Once there is a bad result, it will lead to an inevitable conclusion just because it is too strong and impressive. In the mobile market, the bad place is where you come to the conclusion, which is where the so-called Murphy's Law comes into play.

Huron said: 1 My feeling is that Murphy's Law attaches importance to the possibility, including those small probability events, emphasizes the change and uncertainty of things, expands our thinking or observation horizons, and nip in the bud. At the same time, tell us not to listen to other people's advice, but to look at what others have not seen and think about what others have not thought of, and there may be opportunities to make money in those places.

Surprise is the same, it is a magic weapon for some people. 2. The attention problem mentioned by Chige is only one aspect of Murphy's Law.

We are concerned with selectivity. The world presents us with abundant information, but we usually make limited choices based on our six senses, inner needs, cognition and acceptance. This choice is usually linear and one-sided, and the subject and object are not harmonious. So sometimes after something happens, we pay attention and begin to regret it.

Therefore, I emphasize that the main purpose of Murphy's Law is to break the self-barrier of our inner understanding of the world, so that our attention can spread and flow as much as possible and observe the overall changes. It is like the patron saint of a risk market, making you ready to escape, and then enjoying the joy of harvest; It is also like a searchlight in the dark, illuminating the dead corner of your heart and letting you find opportunities that ordinary people forget.

Murphy's law points out the dilemma of human beings, the weakness of human nature or the paradox encountered, and its direction is often the direction of extreme encounter, or the direction unexpected by ordinary people. So Murphy's law is worth pondering.

3. Murphy's law makes our attention flow and observe the overall changes. -It's just a name, more like a basket.

Everything that is uncertain can be put in. It reminds us in the dark that in the face of anything, we should consider it more thoughtful and comprehensive, and take certain insurance measures to prevent disasters and losses caused by unexpected mistakes.

4. Another expression of Murphy's Law: 1. If you succeed the first time, you obviously did something wrong. 2. If a thing is not worth doing, it is not worth doing well.

Never remember what you have forgotten. When everything is developing in one direction, it's best to take a deep look in the opposite direction.

Today is the end of the first half of your life. 6. Keep it simple-then don't believe it.

7. Education cannot replace intelligence. 8. If you know your value geometry, you will become worthless.
