The Butterfly Effect means that in a dynamic system, small changes under initial conditions can drive the long-term huge chain reaction of the whole system. This is a chaotic phenomenon. There are fixed numbers and variables in the development of everything. There are laws to follow in the development process of things, but there are also unpredictable "variables", which are often counterproductive. A small change can affect the development of things, indicating that the development of things is complex.

Catfish effect: Catfish not only stirs the living environment of small fish, but also activates their survival ability. Catfish effect is a means or measure to stimulate some enterprises to get active and participate in the competition in the market, thus activating the enterprises in the same industry in the market. Its essence is a negative incentive, which is the mystery of activating the staff.

It needs to be emphasized that in some enterprises, because some bureaucrats have been idle for a long time or unable to undertake new tasks and responsibilities, catfish talents have become the driving force for enterprises to improve.

Most kinds of catfish live in fresh water, but some kinds of catfish live in the ocean. (Some scholars have pointed out that the main content of the "catfish effect" has fatal flaws: catfish belongs to fish living in fresh water bodies such as rivers and lakes, while sardines belong to marine saltwater fish. It is necessary to use seawater to transport sardines. Putting catfish into seawater will cause catfish to die, and it is impossible for two species to live and interact with each other. )

At present, the descriptions of catfish effect are all in Chinese, and there is no exact foreign literature citation to show that its source is abroad, and there is no data to show its effectiveness in practice. Please take it into consideration.
