A psychiatric disorder formerly known as “sensorimotor psychosis” in psychiatric textbooks is classified under the current classification system as “delusional disorder. Induced psychosis is characterized by a delusional belief (often a delusion of victimization) held by a dominant or controlling, emotionally close, co-interested person (e.g., husband, father, or mother), who fully accepts the delusional beliefs of that loved one and develops delusions of a sympathetic nature. This type of psychosis occurs in families or groups with minimal or relatively isolated contact with the outside world, where the delusions of the dominant person may be accepted by others. Because the psychosis is influenced by the delusions of others, most delusions disappear completely or are greatly reduced once the person is separated from the loved ones whose beliefs are influenced by the delusions and contact with the normal outside world is restored. This type of psychosis can be seen in members of the same family, or in members of small groups (e.g., cult groups, pyramid schemes) who have been “brainwashed”. In clinical work, such psychosis is indeed a rare phenomenon. However, it seems to me that similar or “inductive” mental problems that do not reach the level of psychosis are extremely common, and have even become a social “nuisance”, but are rarely considered or criticized seriously. For example, the “kidney deficiency” theory, which is very popular among the Chinese, is often a typical example of such inductive beliefs. If the parents of a teenager who has not yet been involved in the world is caught masturbating, and if they believe in the so-called “one drop of sperm and ten drops of blood” or “masturbation hurts the kidneys”, they are often alarmed by this and condemn their child’s masturbation for “hurting the kidneys “The child’s masturbation “hurts the kidneys”, and tells the teenager how terrible “kidney deficiency” is. If the parents then tell the child that “kidney deficiency” can cause dizziness, blurred vision, tinnitus, and weakness in the waist and knees, the child will probably soon have such symptoms. Take some of the health care claims as an example. In recent years, it has become popular to drink water in the morning to maintain health. One argument is that drinking a certain amount of plain water in the morning can “cleanse the intestines” and “clear the stool”. Common sense medical physiology tells us that drinking water on an empty stomach is completely absorbed in the stomach and small intestine, even the colon can not reach, how to talk about clearing the “stool”? Besides, people in the normal intake of mixed diet and gastrointestinal peristalsis, digestion and absorption function is also normal, the digestion and absorption process of food in the stomach and small intestine is about 10 hours or more, by the small intestine absorbed the main nutrients of intestinal contents into the large intestine to form feces also took several hours. If you have a regular bowel movement once a day, the feces below the descending colon is completely excreted, and these gastrointestinal contents from the surimi to the feces remain in the human digestive tract for more than ten hours or even longer, which is itself a “hangover”. The normal bowel movement out since the “feces”, why do you need special cleaning? In addition, the large amount of water in the contents of the colon is also absorbed in the colon, drinking water even if you can enter the large intestine, will not play a role in softening the stool, promote defecation. Although these people who want to drink water to “cleanse” and “clear the stool” may not understand the physiological activities of digestion and absorption of the human gastrointestinal tract, in addition to their own morning water as the “golden rule” to In addition to their own morning water as a “golden rule” to comply with, but also often solemnly ask their spouses, children: “get up in the morning to drink a large glass of water! Wash your intestines, clear your stool, and prevent all diseases.” Thus, their children naturally subliminally accept the parents’ advice, seriously drink up the water. And even pass such a statement to their friends, children, so that the fallacy spread. And say the so-called “stomach cold” argument. Many people may be influenced by traditional medicine, especially parents and elders, since childhood, I heard that the stomach can not be cold, cold will cause indigestion and other problems. Therefore, all the risks that may lead to “stomach cold” should be avoided: do not dare to eat cold food, do not dare to drink cold water, do not dare to eat ice cream, do not even dare to let the upper abdomen exposed to the cooler environment. In the air-conditioned room to sleep, the room temperature of more than twenty degrees, the abdomen have to put on a quilt or other warm items, called “to prevent the stomach from cold”. I do not know, Europe and the United States since childhood to eat cold food, drink cold water, cold drinks, etc., also did not see all suffer from “stomach cold” disease; many Europeans and Americans in the cold season also dressed cool, will not deliberately prevent “stomach cold”. Moreover, a little common sense human anatomy can understand that the abdominal wall has thicker fat, muscle, and rich blood flow, at room temperature even if exposed, will not let the abdominal cavity within the gastrointestinal temperature reduced much. In Chinese folklore, the above-mentioned falsehoods are passed down from generation to generation, and often directly from parents to children. The mental symptoms caused by such fallacies, such as dizziness due to “kidney deficiency”, gastrointestinal discomfort due to not drinking “enough” water in time in the morning, and epigastric discomfort due to occasional cold drinks, are not also inductive mental abnormalities? Therefore, as parents, if you want your children to avoid being poisoned by such false knowledge, is not to believe in these “truths” that you have not thought about, and do not blindly pass these “truths” to your children. Otherwise, when they grow up and have the ability and insight to recognize and criticize such falsehoods, they will probably complain that “all parents are scourges”.
