1, butterfly effect
The butterfly effect was put forward by American meteorologist Lorenz when explaining the air system theory: a butterfly wing occasionally vibrates in the Amazon rainforest, which may cause a tornado in Texas in two weeks.
2. alligator principle
The original intention is to assume that a crocodile bites your foot. If you try to get rid of your foot with your hand, the crocodile will bite your foot and hand at the same time. The more you struggle, the more you get bitten. So, in case the crocodile bites your foot, your only way is to sacrifice one foot.
3, the catfish effect
Norwegians love sardines, especially live fish. But sardines are lazy by nature, do not like sports, and have a long way to return, so the sardines caught often die as soon as they return to the dock. After a long time, it was found that only one fisherman's sardines were always alive and vigorous, so he earned more money than others.
The fisherman kept the secret of success, and it was not until after his death that people opened his fish tank and found that there was only one more catfish. Because catfish mainly eat fish, and sardines will get nervous and swim faster when they find this alien molecule, so sardines will return to the port alive. This is the so-called "catfish effect"
4. Frog phenomenon
At the end of 19th century, Cornell University conducted a famous "frog experiment".
1, boiled frog. When the frog was placed in the boiling cauldron, it immediately jumped out like an electric shock and landed safely.
2. Boil the frog in warm water: When the frog is placed in a large pot filled with cold water and heated slowly, although the frog can feel the change of the outside temperature, it does not jump out immediately because of inertia, and it is too late to wait until the heat is unbearable.
5. Herd effect
Sheep are a very messy organization, and they usually rush blindly together, but once a sheep moves, other sheep will rush headlong into it without thinking, regardless of the possibility of wolves ahead or better grass not far away. Therefore, the "herd effect" is a metaphor that everyone has a herd mentality.
6. Hedgehog Rule
Two sleepy hedgehogs huddled together because of the cold. But because each of them had thorns, they left a distance, but they were too cold to stand, so they got together. After several twists and turns, the two hedgehogs finally found a suitable distance: they can get each other's warmth without being stuck. Hedgehog rule mainly refers to the "psychological distance effect" in interpersonal communication.
7. Watch Law
The law of watches means that when a person has one watch, he can know what time it is, but when he has two watches at the same time, he is not sure. Two watches can't tell a person more accurate time, on the contrary, it will make the person who looks at the watch lose confidence in the accurate time.
8. broken window theory
If the window of a house is broken, no one will repair it, and soon, other windows will be broken inexplicably; A wall, if there is some graffiti that has not been cleaned, will soon be covered with messy and unsightly things; In a very clean place, people are embarrassed to throw garbage, but once there is garbage on the ground, people will throw it without hesitation and feel no shame.
9. The 28 Law
1The Italian economist Valledo at the end of the 9th century and the beginning of the 20th century thinks that in any group of things, the most important thing only accounts for a small part, about 20%, and the remaining 80% is secondary, although it is the majority.
About 80% of society's wealth is concentrated in 20% of people's hands, while 80% of people only have 20% of social wealth. This kind of statistical imbalance is ubiquitous in society, economy and life, and this is the 28 th rule.
10, barrel theory
If the wooden boards that make up a barrel are uneven in length, then the water content of the barrel depends not on the longest wooden board, but on the shortest wooden board. The bucket effect means that if a bucket wants to be filled with water, each board must be equally flush and undamaged. If one of the boards in the bucket is uneven or there is a hole under one board, the bucket cannot be filled with water.
It means that how much water a bucket can hold does not depend on the longest board, but on the shortest board. It can also be called short board effect. No matter how high a bucket is, the height of water it holds depends on the lowest board. Also known as the bucket principle or buckets effect, bucket short board management theory, the so-called "bucket theory" is also known as the "bucket law".
