What were some things in history that were popular for a while but were later confirmed to be seriously harmful?

Human development is originally a process of continuous trial and error and error correction. There are always countless people coming up with all kinds of wild ideas, and then countless people try, study, experiment and draw conclusions. But not everything that has been tested is necessarily correct, because the scientific and technological level and medical level at that time were insufficient, and people could not find the problem at the time. But over time and after a lot of factual verification, we can draw the correct conclusion. In history, there have been some behaviors or research that were once popular but ended up being extremely harmful, such as cry immunization, chicken blood therapy and prefrontal lobotomy.

Everyone is easily blinded by the things in front of them, not because they are too stupid or stupid, but because they stand not high enough and can only see a small part of the things they can see. There is no comparison at all and there is no way to make a correct judgment. And people are the easiest to follow others' opinions. If one person says it, he doesn't believe it, and if two people say it, he doesn't believe it. But when three people say it, ten people say it, or a hundred people say it, everyone believes it. And if this person is a doctor or a highly respected person, then he will be more likely to be convinced. For example, the three cases we are going to talk about today are all jokes led by doctors. They thought they had created miracles, but they had no idea how many people they had harmed.

The first one: cry immunity method.

This is a psychotherapy developed by the famous American psychologist John Watson. It is mainly used for children from birth to under ten years old. It is said that they can actually be trained specifically to allow them to achieve a special response to a certain emotion or thing. The most famous one is crying. Immunization method. Watson believes that the reason why these children cry so much, especially when they are under three years old, is because they believe that crying can threaten their parents and make their parents pay attention to them and comply with their wishes. The cry immunity method he proposed means to ignore children when they cry, or even lock them up alone and let them cry as they please.

At that time in the United States, this therapy was considered by countless Americans to be the gospel to save them, because crying children was really annoying. And after they went through such training, the children seemed to really become quiet and well-behaved. But slowly they discovered that their children were timid, withdrawn, autistic, and even had schizophrenia, mental disorder, irritability and many other psychological problems. Only then did these Americans realize that Watson's treatment was not saving them, but was clearly harming their children. In fact, because Watson treated his children in this way, his children and grandchildren were very seriously affected, and they were very painful throughout their lives. And his theory is still harming Chinese people and Chinese children, and many Chinese people even regard it as truth.

The second one: chicken blood therapy.

Many people find it strange when they hear about chicken blood therapy and don’t quite understand it. In fact, it is to inject chicken blood into the human body in order to increase resistance, enhance immunity, and treat diseases. This was invented decades ago by a Chinese factory doctor named Yu Changshi. By chance, he discovered that the body temperature of chickens was relatively high, and wondered whether there would be a magical effect if chicken blood was injected into the human body. Then I started to experiment on myself. After taking the chicken blood, I felt really energetic and delicious. Then he injected it into his family members, and they all had remarkable effects. Then he began to vigorously promote it, first injecting workers in the factory, and slowly developing to injecting it to many ordinary people. Everyone seems to say it is effective, which increases Dr. Yu's confidence and wants to promote it nationwide.

But later it was discovered that those who had taken chicken blood injections said that their symptoms were relieved, mostly due to psychological effects, and they were only relieved, not cured. Moreover, after taking the chicken blood injection, they also suffered many complications. It is unknown whether anyone died as a result. I only know that after the country completely banned this ridiculous behavior, there were still many people who secretly practiced it, and it was slowly forgotten after more than ten years. If Dr. Yu knew that the body temperature of most animals was this high, would he be so angry at his own stupidity that he would vomit blood?

Third: Prefrontal Lobotomy

This is also a weird treatment developed by weird scientists in the United States.

First, Professor John Fulton of Yale University proposed the research idea of ??improving people's mental state by destroying the prefrontal lobe of the human brain, and then Antonio Egas Moniz carried it forward and did it on the human body. experiment, and finally achieved what he called a success. After prefrontal lobotomies were performed on neurological patients, they all became quiet, compliant, and stopped making noises. This is really good news for treating those neurotic patients who are always hysterical. Moniz also won the Nobel Prize in Medicine.

After that, this technology was used all over the world, and the surgical methods became more and more simple. The people who performed the surgery were no longer neurological patients, but many ordinary people also performed it. But gradually people discovered that people who have undergone surgery have almost become emotionless machines, becoming numb and cold-blooded. Even if they are not careful, their IQ or mobility will be affected due to operating errors. In the end, everyone realized that there was something wrong with this kind of surgery, and various countries slowly gave up on this treatment.

In fact, there are many such shady operations at home and abroad, and they have harmed many people. However, their inventors often receive wealth and reputation, and in the end let ordinary people pay for their stupidity. .
