What is happening in the brain when you cannot agree with the other party's opinion?

When there is a disagreement, it is difficult to convince the other person to get consent . New research is observing what is happening in the brain when disagreements are seen, from which researchers derive 'points to persuade others'.

Here's what happens in the brain when we disagree

University of London psychologists Andreas Capes and Tarri Charlotte conducted an experiment on how the human brain reacts to “disagreement”.
The researchers evaluated 42 real estate members as a pair of 42 volunteers, and spent money based on that evaluation. At that time, researchers record their brain activity with a brain scan. Two paired subjects can see how each other is evaluating and spending money over the glass partitions.
In the experiment, the volunteers basically spent so much money that they were confident in their property evaluation. And if the real estate prices of the two people are the same, each person's confidence is greater and there is a tendency to spend a large amount. At this time, it was confirmed that the brain activity of one volunteer was influenced by the “confidence” of the other. In particular, ' sour grapes , such as typified by', ' cognitive dissonance is said to be related to the' prefrontal cortex is that of the affected confidence of the other party. If one shows confidence, the other becomes more confident.

But when there was a disagreement, the brain was less sensitive to the other's opinion. If you disagree, then your prefrontal cortex will not be affected by your confidence. As a result, when partners with different opinions are confident, they will not be affected by their confidence, regardless of whether their opinions are correct or not. Whether the partner is confident or not confident in his opinion, the result is that the brain is unaffected.
It has been proven that this is not because 'volunteers didn't pay attention to their opponents' because they tested their memory to see if they remembered their valuations and stakes. Researchers believe that when a discrepancy occurs, one thinks that the other is “wrong” and therefore loses importance in that opinion.
The above phenomenon can be confirmed even at the social level. For example, over the last decade, climatologists have repeatedly expressed the opinion that “climate change is caused by humans”. However, a study by the Pew Research Center shows that the number of Republicans who believe in this opinion is decreasing at the same time. Of course, there are multiple reasons for this phenomenon, but researchers say that other people's opinions affect the brain.
So what should we do when there is a conflict of opinions? The first thing to remember is that you don't bring up a lot of evidence that you are right and wrong. Rather, if you start talking about the agenda where you agree with the other, you can avoid being regarded as a “controversial partner” from the beginning and focus on the discussion itself.

For example, if you disagree with someone who thinks that “Vaccines are associated with autism,” you can't change their opinions by presenting scientific evidence about vaccination. Rather, it is easier to get consent if you focus on the fact that vaccines can save children from deadly diseases. In fact, experiments have shown that this persuasion has tripled the willingness to vaccinate.
