Jin Sun- A Chinese with a lifelong interest in the market.

  Before, I didn't want to admit that I was vulgar and ordinary. To make myself look different from others, I even preferred to be a mental patient. Many people have the same troubles as me, thinking that they may be special people. But after in-depth evaluations of themselves, they find that they are ordinary people, and they can't do things to the extreme perfectly, with a correct rate of about 80%. Their lives are characterized by wave-particle duality, switching between what they feel is powerful and what others don't. Different observers make different judgments. Many people accomplish nothing all their lives, but their positioning is biased. My friends were engaged in the education and training for National College Entrance Examination ( NCEE ). They have long studied the real questions of the previous NCEE , counted the proportion of those questions that can be done correctly by repeated training, and also counted the proportion of questions that require certain pro

  When British biologist Francis Galton was young, he was very interested in “ like a father like a son ”, he spent a lot of time studying two issues: If parents are taller or shorter, will the next generation do the same? If parents achieve high success, can their children replicate the success? With the development of modern science, people are no longer satisfied with the conclusions drawn by predecessors but analyze whether the conclusions are true or not from the perspective of statistics. Just like Galileo climbed to the leaning tower of Pisa with two iron balls, and then threw them down to verify whether Aristotle ’s conclusion was correct. According to Francis Galton ’s research, compared with the previous generation, the height and achievements of the next generation have a trend of Mean Reversion . That is to say, parents are very tall, and children will probably shift to a normal state. They will be taller than normal people, but not as much taller than others as parents,

  Nassim Nicholas Taleb  is the author of  The Black Swan , a thoughtful man. I’ve read his books and made many notes. I think his articles are valuable to us. I’d like to use Taleb’s theory to read some interesting phenomena. Hormesis Most people think that eating vegetables is good for human health because they can supply us with vitamins and cellulose, which is the key to nutrition. The main reason why vegetables are beneficial to human health is that they are poisonous. During the evolution of vegetables, to prevent them from being eaten by humans, certain toxins have evolved. After eating vegetables, humans will have stomachaches or be in a trance, which will lead us to run away when we see it next time. Unexpectedly, all living things are evolving. Instead of scaring people, the toxins in vegetables stimulate the potential of human bodies that eat poisonous vegetables. We may have been poisoned once, but after adapting to this toxin, we become more resistant. From the biological
