The Hong Kong "South China Morning Post" website published a report on "The Brain of Corrupt Officials, How Is It Different from Us?" on July 5, saying that people will accept bribes without hesitation, or will they think twice? Scientists believe that this problem may be Find the answer in the left brain. This argument prompted the outside world to discuss whether drugs or treatments could be used to suppress the tendency to corruption.
The scientific community has been looking for a neural mechanism to explain why people's behavior deviates from social norms.
Mainland behavioral neuroscientists have recently focused on a small area above the left and right frontal back of the brain. The research report was published in the international journal Frontiers of Behavioral Neuroscience. The report said that when “people would rather sacrifice moral codes to pursue wealthâ€, this part of the region played a “key roleâ€.
The research team was led by Li Wei, a professor at the Institute of Psychology of the Chinese Academy of Sciences. The team found that the more the amount of bribes received, the greater the stimulus to the brain.
The researchers designed a game for 28 volunteers. Each participant received a sum of money, and the amount gradually increased from 8 yuan to 3,000 yuan.
Each time a participant is funded, the researcher asks if they would like to share the money with others. If accepted, participants will receive a certain percentage of the money. If it is rejected, no one can get any money. Li Wei said that this situation is similar to accepting bribes.
Volunteers were placed in MRI machines to record their brain activity. Volunteers are asked if they accept money and then press the "Yes" or "No" button. Researchers have found that, regardless of the amount of money, providing money to volunteers stimulates the “pleasure†of their brains: the right prefrontal cortex and the bilateral insula. The two are located on the front and side of the brain. When volunteers decide to accept a certain percentage of money, their activation of the left frontal back is stronger than other areas. The more money, the stronger the activation.
Not all participants respond equally to high-risk money. The more active the left frontal activity, the more inclined to pursue the principle of fairness and pursue money. In other words, they are more likely to be “buyâ€. Li Wei said that the research results may further clarify why and how corruption occurs.
Ge Jianqiao, a doctor of neurology at Peking University, believes that studying the brain function of corrupt officials may help to discover the link between the brain and corrupt behavior. This is an interesting topic for scientists and is very important to society. But there are still many technical difficulties in scanning the brains that have been convicted of corrupt officials. If you want to compare, the researchers first need to build a "normal brain" model. So who should be compared with corrupt officials? Is it an ordinary citizen or another official who is under the same job pressure?
Ge Jianqiao also said that corruption may also be affected by several social and biological factors, such as financial and health conditions. However, if the act of accepting bribes is found to be related to the brain, scientists can study alternative methods to adjust human behavior, including medication or psychotherapy.
Cao Jun, a neuroscientist at the Kunming Institute of Zoology, Chinese Academy of Sciences, warned that any study requires not only subject consent but also government approval. Unauthorized, no scientist can scan the brains of former government officials in prison. Corrupt officials who have been convicted may not be willing to help with research. Although everyone hates corrupt officials, they are also human beings who cannot detect their brains without consent.
