The Law of Two-Eight:

In 1897, the Italian economist Pareto happened to notice the pattern of wealth and earnings of 19th-century Britons. In his survey sampling, he found that most of the wealth went to a few people. At the same time, he also found from earlier sources that this subtle relationship was found again and again in other countries urging only mention of the family, and mathematically present a stable relationship.

So Pareto found from a large number of specific facts: 20% of the people in the society occupy 80% of the social wealth, that is: the distribution of wealth in the population is unbalanced.

At the same time, people also found that there are many imbalances in life. As a result, the law of two-eighths became a shorthand for this unequal relationship, regardless of whether the results are exactly 80% and 20% (statistically speaking, the probability of the exact 80% and 20% occurring is very small). By convention, the law of two-eight discusses the top 20%, not the bottom 80%. The law of two-eight, as it has been adopted, is a quantitative empirical method for measuring the possible relationship between inputs and outputs.

The Law of the Wooden Barrel:

The Law of the Wooden Barrel talks about how much water a barrel can hold depending on its shortest plank. If a barrel is to be full of water, every plank must be equally flush and unbroken. If one of the planks of the barrel is not flush or if there is a hole underneath one of the planks, the barrel will not be full of water. The amount of water a barrel can hold does not depend on the longest plank, but on the shortest one. It can also be called the short board effect.

An organization, may face a **** the same problem, that is, the various parts of the composition of the organization is often the advantages and disadvantages, and the inferior part often determines the level of the whole organization. Therefore, the whole society and each of us should think about their own "short board", and make up for it as soon as possible.

Birdcage Logic:

Birdcage logic is considered one of the 10 human irresistible psychology, which is an effect induced by a psychological story. Hang a beautiful birdcage in the most prominent place in the room, and within a few days the owner is bound to make one of two choices: throw the birdcage away, or buy a bird and put it back in the birdcage, because it's easier than endless explanations and instructions.

This is birdcage logic. The reason for birdcage logic is simple: people overwhelmingly adopt inertia. It's not necessarily true that every beautiful birdcage should have a bird in it, but unfortunately people can't escape the confines of this logic. So you can see how important it is to develop logical thinking in life and work.

The sea pavilion leaps by the fish, the sky is high enough to let the birds fly. Don't limit your thinking, and don't stop under the scrutiny of conventional eyes. Dare to hang out an empty birdcage and be able to naturally adhere to the person is creative. The person who has the courage to advocate.

Hedgehog's Law:

Hedgehog's Law is a very interesting phenomenon: in a cold winter, two sleepy hedgehogs embraced because of the cold, but in any case, they can not sleep comfortably, by drying their respective bodies are full of thorns, close to each other in a piece will be pricked each other, and in turn, sleep is not peaceful. So the two hedgehogs moved away from each other for a while, but the cold was too much to bear, so they hugged each other again.

After a lot of trial and error, they finally found a more suitable distance where they could keep each other warm without being stabbed. This is the "psychological distance effect" in the process of interpersonal communication. The so-called "hedgehog law" is that in order to study the hedgehog's habits in the cold ling days, biologists did an experiment: put a dozen hedgehogs outdoors in the open space.

These hedgehogs were shivering, in order to keep warm, they had to cling to each other, and each other close together, Wen because they could not stand each other's long spines, and soon to be separated. But it was so cold that they leaned together again to keep warm. However, the sting of leaning together makes them have to separate again, too close to each other, their bodies will be stung: too far away, and freezing.

And so it went on, back and forth, back and forth, back and forth, constantly struggling between the cold and the thorns. In the end, the hedgehogs finally found a moderate distance, can warm each other, but not to be stabbed by each other. This shows that people need to maintain a certain spatial distance between them. Everyone needs to have a self-space that can be grasped by his own side, which is like an invisible bubble" like a certain area for himself.

When this "field" is violated by others, people will feel uncomfortable. It's not safe, and it's even irritating.

The Matthew Effect:

The Matthew Effect, a phenomenon in which the strong get stronger and the weak get weaker, is widely recognized. The Matthew Effect, a phenomenon in which the strong get stronger and the weak get weaker, is widely used in the fields of social psychology, education, finance, and science. There is a parable in the Gospel of Matthew in the Bible: "Whoever has, let him have twice as much, so that he may have more than enough; and whoever does not have, let him have all that he has". On the face of it, the "Matthew Effect" is contrary to the "Way of Balance".

It is similar to the "rule of two or eight", but in fact it is only one pole of the balanced way. The Matthew effect is a common term used by sociologists and economists, reflecting the polarization of society, with the rich getting richer and the poor getting poorer.
