Wolf postulates that this is the result of his not being affiliated with a major university.

However, the term - the coefficient of intelligence - was invented and put into circulation by the German psychologist and philosopher William Stern in 1912. The first test, developed by Binet and his colleague Simon, became globally famous. The basis of modern IQ tests is formed on the distribution of points. Because of this, the term "intelligence factor" is nonexistent in fact, but it is still widely accepted. Modern tests, or as they are often called, WAIS, are used to calculate IQ. These tests are more recent and are used to solve long-term problems, for which special surveillance is needed.

There are many debates about what affects the results of IQ tests.

It is worth noting that some people with an exceptionally high Ai Kew in everyday life turned out to be completely helpless. For example, Kim Peak could not fasten buttons on his clothes.

How to evaluate intelligence?
To evaluate intelligence, the test administrator uses the Draw-a-Person: QSS (quantitative scoring system). This system analyzes fourteen different aspects of the drawings (such as specific body parts and clothing) for various criteria, including presence or absence, detail, and proportion. Goodenough's original scale had 46 scoring items for each drawing, with 5 bonus items for drawings in profile. Harris's scale had 73 items for male figures and 71 for female figures. More recent versions use 64 scoring items for each drawing. A separate standard score is recorded for each drawing, and a total score for all three. The use of a nonverbal, nonthreatening task to evaluate intelligence is intended to eliminate possible sources of bias by reducing variables like primary language, verbal skills, communication disabilities, and sensitivity to working under pressure. However, test results can be influenced by previous drawing experience, a factor that may account for the tendency of middle-class children to score higher on this test than lower-class children, who often have fewer opportunities to draw.
Who developed the Goodenough test?
Developed originally by Dr. Florence Goodenough in 1926, this test was first known as the Goodenough Draw-a-Man test. It is detailed in her book titled Measurement of Intelligence by Drawings. Dr. Dale B. Harris later revised and extended the test and it is now known as the Goodenough–Harris Drawing Test. The revision and extension is detailed in ...

Did Harris find validity in personality testing?
Likewise, Harris found no validity in personality testing through human figure drawing. He rejected the use of "an elaborate theory of symbolism" to interpret the stylization of features, instead preferring to let the child lead with a simple "Tell me about it" after the drawing.
Who wrote the Origin of Consciousness in the Breakdown of the Bicameral Mind?
Psychologist Julian Jaynes, in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wrote that the test is "routinely administered as an indicator of schizophrenia ," and that while not all schizophrenic patients have trouble drawing a person, when they do, it is very clear evidence of a disorder.
Is the Draw a Person test a measure of intelligence?
The Draw-a-Person test is commonly used as a measure of intelligence in children, but this has been criticized. Harlene Hayne et al. compared scores on the Draw-A-Person Intellectual Ability Test to scores on the Wechsler Preschool and Primary Scale of Intelligence in 100 children and found a very low correlation (r=0.27). Similarly, results found with child and youth psychiatric inpatients failed to support the hypothesized relationship between human figure drawings and IQ. This suggests that the Draw-a-Person test should not be used as a substitute for other well-established intelligence tests.
