After thinking about it, I felt that something must have gone wrong. Everything in real life can be explained by theory, so I wonder if this is one of human irrational cognition: poor confirmatory deviation. Confirmatory prejudice means that once people form an opinion, they will look for evidence from the side of affirming their own views, not from the side of denying themselves. The reality is that there are both positive and negative information, and you just choose the information that is beneficial to you purposefully. Usually, you can always find the information you want, but that doesn't mean that your decision is correct.
In fact, it is very difficult to break this cognitive bias, because we usually don't doubt our own ideas. At this time, I think people can be divided into those with strong metacognitive ability and those with weak metacognitive ability. Only those with strong metacognitive ability will doubt whether their views are correct and then make changes. But people are often highly confident, and it is difficult to deny and doubt themselves. Everyone has a need to prove that he is right, sometimes it is related to interests, sometimes it is related to face.
Of course, I also thought I should do this, but I persuaded my classmates. The question is to what extent he can listen to my point of view. It is more convincing to prove it with data. Although I don't have the data at first, it's not difficult to draw a correct conclusion if I think about this problem carefully. Faced with too many cases in which the elderly are seriously ill, the next generation has to choose between two kinds of treatment or no treatment. However, the future living conditions of the next generation will be related to his attitude of helping their parents. In fact, it is easy to find out a few unfortunate events that occurred because of advocating treatment, and it is also easy to find out unfortunate events that do not advocate treatment. Of course, if it is the latter, people are even more reluctant to talk about it. So if there is data, everything will be understood from the perspective of data. The so-called mysterious power is only caused by our ignorance of confirmatory prejudice.
Xiong Yi's words are particularly impressive: "Ji Kang was a shining intellectual elite in the Three Kingdoms period. He is very clever and learned. He wrote an article on keeping in good health, discussing the problem of immortality. He believes that although no one has seen immortals in real life, there are always so many fairy stories recorded in various books and history books that they can't all be fictional, so immortals must exist. We really shouldn't blame Ji Kang, because he didn't know at that time that people can easily believe what they want to believe, and the market especially likes to satisfy people's wishes. If everyone wants the earth to have two moons, there must be many mysterious records about the second moon. "
