What does Murphy's Law mean?

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.

Murphy's law, Parkinson's law and Peter's principle are called the three great discoveries of western culture in the 20th century.

Murphy's law has four 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 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.

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.
