Why is it good luck to step on shit with your left foot and bad luck with your right foot in France?

This is superstition. China jumped with his left eye for money and jumped with his right eye for disaster.

Broadly speaking, superstition refers to people's blind belief or worship of things. Superstition in a narrow sense, according to the established habits after liberation in China, refers to people's thoughts and behaviors of believing in astrology, divination, geomantic omen, fate and ghosts and gods. Superstition activities generally refer to folk activities such as gods, witches, fortune telling and geomantic omen, such as lottery, divination, fortune telling, geomantic omen, exorcism, and jumping.

Some researchers believe that superstition can also be defined as a "wrong" connection between the real world and supernatural phenomena. Some researchers also pointed out that superstition is a by-product of adaptive strategy evolution and a means of survival. A large number of behavioral research results reveal that people tend to be superstitious when they lack self-control, especially when most people in the group show superstitious behavior, and the herding effect will make superstition more intense.

So, will the activity of the cerebral cortex be related to superstitious behavior? Recently, researchers from the Key Laboratory of Behavioral Science, Institute of Psychology, Chinese Academy of Sciences tried to directly test whether superstition really caused related reactions in our human cerebral cortex with the help of functional brain imaging technology.

First, people would rather sacrifice real and visible money for false and intangible luck;

Second, this false and invisible thing does have a solid neural foundation;

Thirdly, the brain imaging data of the subjects with higher degree of superstition in the answers of superstition scale show that the difference of activation degree between superstitious choice and non-superstitious choice is greater in the middle and upper right frontal lobe.

Based on the above findings, the researchers speculate that the subjects are weighing the known cost of money and the potential "auspicious" benefits when choosing. When he finally chose an auspicious day, it was the result of the suppression of rational thinking. Maybe we can connect or inhibit the activities of superstitious brain regions by establishing correct conditions, so as to change some stubborn superstitious behaviors.

In fact, superstition is "irrational belief in a certain behavior or etiquette", which is a feudal bad habit left over by China for thousands of years. In the face of natural disasters, poverty and hardship, and lonely promotion, superstition has given the working people a spiritual expectation and strength. However, feudal superstition is different from religious superstition. It has no formal organizational form, no fixed classics, doctrines and places, and its behavior results are mostly aimed at fraud, which is the object of severe crackdown and ban by the state. To put it bluntly, superstition is not credible, so some people still believe it. The main reasons are nothing more than: first, fear of the unknown; Second, lazy thinking makes people unwilling to think.

Every region has superstitious activities, so France says so.
