What is considered normal IQ

Normal person: 85~115 points; Smart person: 120~140 points; Genius: 140~200; Border value: 71~84;

Mild mental retardation: 50-70 points, intelligence equivalent to children aged 8-10 years old

Moderate mental retardation: 35-49 points, intelligence equivalent to children aged 3-5 years old

Severe mental retardation: 20 to 34 points, the quality is equivalent to a 3 to 5-year-old child

Extremely severe mental retardation: 20 points or less, the intelligence is equivalent to a 2-year-old baby

Edison’s IQ is 135. IQ is the abbreviation of intelligence quotient. It is an important concept that uses numerical values ??to express the level of intellectual development. IQ IU = mental age/actual age * 100. The so-called mental age refers to a person At the level that an intelligence test can achieve, for example, a 5-year-old child can pass the 5-year-old intelligence test and the 6-year-old intelligence test, but cannot pass the 7-year-old intelligence test. Then the child's mental age is 6 years old, and his IQ is 6/5*100=120. The higher a child's mental age exceeds his actual age, the higher his IQ.

The normal range of IQ is 70-130, with an average of 100, 10-15, that is, 85-115, which is average, 115-130, which is upper-level, above 130, which is extraordinary, and 70-85, which is average. If a child's IQ is below 70, we cannot easily say that he is mentally retarded. Only when the child pays attention to the fact that IQ testing has great limitations, because it can only measure the current level of the child's intelligence, but cannot measure the child's potential ability of intelligence, because the child The development of children is affected by the environment and education, and the development process will change in the future. Moreover, children's intelligence can only be evaluated quantitatively, not qualitatively, because IQ is only a numerical value and cannot reflect the differences in children's intelligence. It shows that a person's academic performance cannot predict a person's future achievements. Some psychologists believe that human intelligence should be divided into six types, namely, linguistic intelligence, musical intelligence, logical and mathematical intelligence, spatial relationship intelligence, body motor intelligence, and self-awareness. Intellectual intelligence, the intelligence test we currently use cannot measure all 6 types of intelligence, so it only tests the child's poor IQ at the moment, which cannot explain future problems. Sometimes the child is too nervous when testing, which affects the test results, and it cannot explain the child's IQ. The real situation is that children whose IQ is between 60-70 must be analyzed and evaluated based on the child's social adaptability. If the child's social adaptability is lower than that of children of the same age, only when the IQ is below 70 points can the child's intellectual development be considered lagging. Educational help should be strengthened, and education for children with high IQs should not be relaxed.

Eating more alkaline foods can improve IQ

British scientists believe that the acidity of human brain fluids is related to IQ. Within the allowable range of the acidity of body fluids, when it is acidic, the IQ is low; when it is neutral, the IQ is high. When scientists observed 42 boys aged 6 to 13 years old, they found that those with a pH value of body fluid in the brain greater than 7.0 had twice the IQ of those with a pH value less than 7.0.

Since the acidity of body fluids can be adjusted through diet, scientists have suggested improving the diet structure and eating more alkaline foods to improve intelligence. (Inspirational personalized signature)

Scientists suggest that children should eat less fish and meat, and eat more soy products and dairy products; eat less oily foods and more fruits and vegetables; eat less sweets and more seafood. This kind of eating habit is beneficial to improving people's IQ, especially children.
