Prejudice is associated with the structure of the human brain, a study has found

does this bias come about? According to a brain science study published in the British Journal of Nature Neuroscience on the 16th, the inner pre-cortectric cortectric (pMFC) may promote the human error of confirmation. Specifically, the inner frontal cortique is less sensitive to opinions that do not make them more convinced of existing ideas.Humans tend to ignore information that undermines past choices and judgments. From politics to science and education, this confirmation bias has important implications, but the mechanisms behind the characteristics of this belief have been little known.For this reason, researchers Andres Karpas and Tarry Sharoth of City College, University of London, among others, hypothesis that the process may occur at the back of the inner pre-frontal cortical cortical, a position responsible for tracking decision-making information and signaling when decisions should be changed.The team grouped 42 adults into groups of two and asked them to separately determine whether the listing price of the property was higher or lower than the display price. After that, the subjects bet on confidence in their judgment - between 1 and 60 cents. Next, each subject enters an MRI scanner, where the experimenter again shows them real estate information and reminds them of their initial judgment and bets. They then saw their peers' judgments and bets on the same real estate information, when they were asked to submit a final bet - showing their confidence in their initial judgment.The team found that when a peer's judgment confirmed a subject's initial judgment, the subject increased the final bet, which was associated with the peer's bet. The researchers also identified activity at the back of the inner pre-frontal cortique, which regulates the effect of peer bets on the final bet, but only if the two are judged consistently.This indicates that the inner frontal cortectal back is sensitive to each other's opinions only if the two agree, and in the case of inconseconcency, sensitivity decreases, which can lead to incorrect confirmation.

When a person has made a choice, he or she instinctively seeks additional evidence to prove the rationality of his choice. If new information does not match the original information, people will instinctibly resist. Self-refutation is too difficult, and psychologists have found many ways to explain this mechanism. And with the further study of the brain, we can actually find that many seemingly unreasonable behavior, is a part of the brain in the "doing." In this way, human "irrationality" is actually rooted in our biological structure, it is difficult to change.
