The decision-making system is so important, then what is the most important in the decision-making system? I think the most important thing is the error correction mechanism.
 

After the reform and opening up, China has undergone changes and formed a corrective mechanism. For the error correction mechanism, an important premise is that the information channel must be unobstructed, and the information transmission mechanism must be sound. The decision-makers must be able to grasp the correct information in time and discover the signs of errors in time to correct the errors in time.
 

This requires shortening the chain of information transmission as much as possible, and reducing the transmission links in case the information is leaked or distorted during the transmission process. The most frightening thing is that the information transmission chain is too long, the transmission links are too many, the layers of news are not reported, the layers of information are discounted, and the real information is hidden intentionally or unintentionally, making the decision makers become "scorpions" and "scorpions". Decision making becomes blind decision making. According to the principle of cybernetics, when the big ship itself has deviated from the route, if the feedback signal still shows “normal navigation”, it will cause the driver to misjudge, and eventually the big ship will hit the iceberg. Therefore, according to the "crisis management theory", once a crisis occurs, it indicates that there is a problem with the existing information channels, and the information is blocked. Only by mastering the real situation can you make fewer mistakes and make no mistakes.
 

Another point of view is that throwing stones and driving cars is an emergency. However, emergency hedging requires a critical situation and risk aversion is to protect more important legal interests. Here, the stone throwing car is probably not forced by the situation. More importantly, the driver involved in the property is the property law, while the stone throwing injury to the girl is a personal legal benefit, which also does not meet the requirements of emergency hedging.
 

The driver forced the Leica to evade the fee, and the toll station staff could intercept the victim without jeopardizing the health of others. If the interception fails, the police should call the police for help. Acts like smashing stones and smashing cars are too impulsive or sloppy, beyond the necessary limits, and are not appropriate. Therefore, the staff of the toll booths are also responsible for the injury to the girl. However, given that the Leica driver is at fault, the liability can be appropriately reduced.
