I forgot where I heard this effect. It says that if you always think about the bad things, things will develop for the worse.

This effect you heard is actually Murphy's Law.

1. What is Murphy’s Law

Murphy’s Law is a psychological effect proposed by Edward A. Murphy, an American engineer in 1949 , also known as Murphy's law, Murphy's theorem, etc.

Murphy's Law: If there are two or more ways to do something, and one of the choices will lead to disaster, someone will make this choice. The bottom line is: if there is a chance that things will go bad, no matter how small the possibility, it will happen.

The summary is as follows:

Nothing is as simple as it seems;

Everything will take longer than you expect;

< p>What can go wrong will go wrong;

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

2. The origin of Murphy’s Law

In 1949, an Air Force captain engineer named Edward Murphy casually said something to one of his unlucky colleagues. As a joke: If something is likely to be done badly, it will definitely be worse if he is asked to do it.

The originally innocent joke did not have a deep meaning at first, it just expressed the helplessness brought by bad luck. Maybe it’s because there are too many unlucky people in this world, or maybe it’s because people always make mistakes of one kind or another. This sentence spread quickly, and finally it was interpreted as: If bad things are possible, no matter how small the possibility is. , it will always happen and cause the greatest possible loss.

3. Mathematical Reasoning

In mathematical statistics, there is an important statistical rule: Assume that the probability of an unexpected event occurring in an experiment (activity) is p (p>0 ), then the probability that at least one occurrence occurs in n experiments (activities) is P=1-(1-p)n. It can be seen that when the number of experiments n approaches infinity, pn will increasingly approach 1, which becomes an inevitable event.

This conclusion was applied to safety management by Edward Murphy. He pointed out: When doing anything, if there is an objectively wrong approach, or there is a possibility of some kind of accident. , no matter how small the possibility is, when doing this thing repeatedly, an accident will always happen at some point. In other words, as long as the possibility of an accident exists, no matter how small the possibility is, the accident will happen sooner or later.

4. Coping methods

To break the "curse" of Murphy's Law, we must have firm self-confidence, a stable mentality, positive psychological hints, and use affirmative language to do things. Explain that you should adopt a zero-tolerance strategy for negative emotions or bad thoughts such as inferiority complex, and get rid of them as soon as you notice them. Even if you encounter setbacks, you must have the awareness to "do your best in everything and everyone and obey fate", give full play to your potential and deal with it bravely, and always face life with a positive and sunny attitude.

In addition, when doing things, try to follow the correct process and do not change things on your own to avoid the risk of making mistakes.
