Prejudice is related to the structure of the human brain

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.
tend to ignore information that undermines the choices and judgments of the past. 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.
In view, researchers Andres Karpas and Tarry Sharoth of City College, University of London, among others, hypothesically assume that this process may occur at the back of the inner frontal pre-cortical cortical, a position responsible for tracking decision-making information and signalling when decisions should be changed.
team grouped 42 adults into groups and asked them to separately determine whether the listing price of the property was higher or lower than the price shown. After that, the subjects bet on confidence in their judgment - between 1 and 60 cents. Next, each subject enters an MRI scanner, and the experimenter shows them real estate information again 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.
team found that when a peer's judgment confirmed a subject's initial judgment, the subject increased the final bet, which was related to 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 suggests that the inner frontal cortectric back is sensitive to each other's opinions only if the two agree, and that in the case of inconseconcies, sensitivity decreases, which can lead to misconfirmed confirmations.
