What is Murphy's law, a magical law recognized by western society?

Murphy's law is often used by pessimists as an excuse to excuse their pessimism. Use an image example to illustrate, that is, if you have a piece of bread with jam on one side in your hand, if the bread falls. I'm sure it will land next to jam.

In fact, Murphy's Law is a psychological effect put forward by Edward A. Murphy, also known as Murphy's Law and Murphy's Theorem. If there are two or more ways to do something, one of which 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.

Together with Parkinson's law and Peter's principle, it is called the three major discoveries of western culture in the twentieth century.

An air force captain engineer named eddie murphy played a casual joke on his unfortunate colleague in 1949: "If something is likely to be done badly, you let him do it worse."

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

There is an important statistical law in mathematical statistics: 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 (that is, small probability events), when n is getting bigger and bigger, p is getting closer and closer to1.

Eddie murphy applies this law to safety management. He pointed out that 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.

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.

To pessimists, Murphy's Law is an excuse to deny all efforts. To optimists, Murphy's Law is indeed a ray of hope for success. So the most important thing is that people's mentality determines the success or failure of things.
