1, things that can go wrong will always go wrong;

2. Everything will take longer than you expected;

3. Nothing is as simple as it seems;

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

The premise of Murphy's law is that the probability of an event is greater than zero; The sample is large enough (for example, the time is long enough and the number of people is large enough).

Extended data:

1. Psychological control is the core and the most inspiring goal. Control means making behavior happen or not-initiating it, maintaining it, stopping it, affecting its form, intensity or incidence.

2. Psychological effect is a common psychological phenomenon and law in social life; It is a causal reaction or chain reaction that the behavior or function of one person or something causes other people or things to change accordingly.

3. Murphy's Law was born in the middle of 20th century, which is an era of rapid economic development, continuous progress in science and technology, and human beings truly become the masters of the world. Murphy's law, Parkinson's theorem and Peter's principle are called the three great discoveries of western culture in the 20th century.

4. The simplest expression of Murphy's Law is that things that may go wrong will go wrong; There will be mistakes, and eventually there will be mistakes. Murphy's law is simply: when it seems that a good thing and a bad thing have the same probability, everything will happen in a bad direction.
