Norwegians like sardines, especially live fish. After catching sardines at sea, if they can reach the port alive, the selling price will be several times higher than that of dead fish. However, because sardines are lazy by nature, do not like sports and have a long way to return, the caught sardines often die as soon as they return to the dock, even if some are alive, they are dying. There is only one fisherman. His sardines always live vigorously, so he earns more money than others.
The fisherman kept the secret of success until his death, when people opened his fish tank and found that it was just an extra catfish. It turns out that catfish live on fish. After being put into the fish tank, they will swim around because of unfamiliar environment. When sardines find this alien molecule, they will become nervous and swim faster. In this way, the sardines will return to the port alive. This is the so-called "catfish effect". Using this effect, individuals can play a competitive role in the group through "midway intervention", which is in line with the operation mechanism of talent management.
At present, the open recruitment and competition for posts implemented by some government agencies and units are good examples. This method can make people feel a sense of crisis and work better.
