Knowing the information in advance may not be good

 An American, out of curiosity, did a genetic test to trace his ancestors, and the results confirmed what he had been skeptical and did not want to accept: he was a hybrid of Eastern European and Ashkenazi Jews. After that, he went to the hospital to analyze his DNA and learned that his genome was at risk of genetic diseases. At this time, he was very depressed and began to reflect on his behavior, why should he spend time and energy to know these depressing news-some information that he doesn’t actually need to know!
  In daily life, many people can’t wait to know a lot of news, and the sooner they know, the better. But is this practice really good for people?
  In fact, it is not necessary to rush to explore many unknown information that does not affect one’s daily life, and it is even useless to people!
  However, some people have raised questions. In some cases, if you understand your own genetic risk as soon as possible and the methods to reduce this risk, it may allow people to avoid it in advance and live a healthier life. Isn’t that many benefits? So why did the actual results of the Americans in front of them backfire? For this reason, neuroscience experts decided to do some in-depth research to understand the two states of “prophet” and “after knowing”, which makes people live a happier life.
  The mysterious role of dopamine
  in order to understand “prophet” and “hindsight” which make people happier, we first need to look at the body of mysterious substances – dopamine.
  Dopamine is a neurotransmitter related to human lust and feeling. Its function is to transmit information of excitement and joy between brain nerve cells. People are easily obsessed with things that make them happy or excited. Therefore, people’s addiction to some things is mainly due to dopamine.
  Therefore, people feel that happiness is mainly the result of the excitement and joy of dopamine.
  So, what does dopamine have to do with the “prophet” and “the hindsight?
  Scientists from the National Institutes of Health conducted an experiment in which monkeys were trained to look at the screen in exchange for the reward they wanted. The monkeys have two screens to choose from: the first screen is a landscape painting that has nothing to do with the reward content, but there will be rewards after seeing the screen; the second screen is a picture showing the rewards they will receive. It turned out that the monkeys eagerly looked at the second screen, and when the monkeys saw the picture of the reward they would receive, the dopamine in their brains had been significantly increased! This means that the monkeys are already very excited and happy when they see the prize they are about to receive, even if they have not yet been rewarded.
  This finding points out that both the news of rewards and the rewards that are about to be obtained can increase dopamine in the brain and make people “excited.” This provides an explanation for why people “especially want to know the results”.
  The bad news affects people’s mood
  , however, dopamine can not just react to good news, it is also equally bad news! In 2018, researchers at the University of Melbourne in Australia found that when humans get bad news, dopamine in the brain also responds significantly.
  In their experiment, the researchers recorded the brain activity of 22 participants playing card games.
  This is a new game that no one has ever played. There are five cards that are either black or red in the game. The rule of the game is that the number of red cards is greater than the black cards, which means victory. Before the game starts, players have two options: one option is to not know the rules of the game all the way, just play, and finally see the results, the other option is to know the rules of the game in advance, at the cost of deducting a certain fee from the final bonus.
  For those who choose not to know the rules of the game at all, there is no response to the flipped cards. But for those who have spent money on the gossip, a red or black card will let them know that when the final result may be lost, dopamine signals will also appear in the brain, which indicates that people are beginning to become nervous. Emotions have more obvious fluctuations.
  The results of this study show that when people can’t get the “good” results that people expect, they will feel sad and lost. Therefore, knowing some information in advance is not a safe and good thing for people! Especially for some people with congenital heart disease, if they habitually inquire about unknown information, it happens that a considerable part of it is disappointing or even frustrating, which will cause their discomfort and even affect their health. And if you don’t explore this information, people may maintain a stable mood without uncomfortable mood swings.
  ”Ignorance” is also a blessing. In
  2018, a joint research team from the United Kingdom and the United States launched a new study on card games. At the beginning of each round, players will see their probability of winning in this round, and can also decide for themselves whether they want to know the final result of the superposition after several rounds in advance. But whether or not participants choose to know, it will not affect their total income.
  The research team found that after several rounds of draws and feel that their ultimate probability of winning is high, most people choose to be informed of the final result in advance to feel the joy of victory in advance. At this time, the dopamine in their brains is very active; but when they feel that their final probability of winning is small, few people choose to know the result in advance. The data recorded by the researchers showed that when the potential failure results are not expected to be known, the activity level of dopamine-secreting areas in the brain is low, that is, people’s excitement is low.
  From the results of the research, our brains are actually willing to approach positive information and avoid negative information.
  So why should people avoid negative information? Scientists believe that knowing some negative information in advance will lead to panic and loss of happiness. Conversely, when people have good expectations for what will happen, we will feel very happy earlier. Therefore, avoiding knowing potential negative information in advance can not only reduce the sense of worry in life, but also help people maintain positive beliefs.
  The scientists concluded that the results of years of research on the brain show that because life is impermanent, the results are not all good. We might as well control the desire to know certain information in a hurry, and pursue everything naturally, which is more conducive to us building a sense of happiness and maintaining a positive life state.
