What is the IQ range of normal people?

IQ grade:

/kloc-genius over 0/40 or close to genius?

120- 140 Excellent intelligence?

More intelligent 1 10- 120?

90- 1 10 general intelligence?

80-90 is slow, even if it is retarded.

70-80 is between slow energy and low energy (each can be classified as low energy)?

Below 70, it is determined to be low energy.

Extended data IQ, that is, IQ, is an indicator of individual intelligence test scores and the scores of subjects of the same age, and is a standard to measure individual intelligence. The concept of IQ was put forward by Stanford University psychologist Professor Terman.

People with an IQ of 200, 90 ~ 1 10 belong to the normal intelligence range, those with an IQ of 120 ~ 140 are smart people, and those with an IQ of 140 or above are called geniuses. The lower the score, the worse the intelligence. Anyone below 70 points is mentally retarded. Among them, 50-70 points are idiots, 25-50 points are dementia, and 0-25 points are idiots. ?

1904 originated in France. This value is not used to test the knowledge, but to judge the working ability of the brain. The average person's IQ is between 85- 1 15, and the average human IQ is 100.
