_E. F. Russian boy, age 8-5; mental age 13; I Q approximately 155._ Mother is a university student apparently of very superior intelligence. E. F. has a sister almost as remarkable as himself. E. F. is in the sixth grade and at the head of his class. Although about four grades advanced beyond his chronological age he is still one grade retarded! He could easily carry seventh-grade work. In all probability E. F. could be made ready for college by the age of 12 years without injury to body or mind. His mother has taken the only sensible course; she has encouraged him without subjecting him to overstimulation. E. F. was selected for the test as probably one of the brightest children in a city of a third of a million population. He may not be the brightest in that city, but he is one of the three or four most intelligent the writer has found after a good deal of searching. He is probably equaled by not more than one in several thousand unselected children. How impatiently one waits to see the fruit of such a budding genius! _B. F. Son of a minister, age 7-8; mental age 12-4; I Q 160._ Vocabulary 7000 (12 years). This test was not made by the writer, but by one of his graduate students. The record included the _verbatim_ responses, so that it was easy to verify the scoring. There can be no doubt as to the substantial accuracy of the test. This I Q of 160 is the highest one in the Stanford University records. B. F. has excellent health, normal play interests, and is a favorite among his playfellows. Parents had not thought of him as especially remarkable. He is only in the third grade, and is therefore about three grades below his mental age. [Illustration: FIG. 16. BALL AND FIELD. B. F., AGE 7-8; MENTAL AGE 12-4; I Q 160 (This is a 12-year performance)] It is especially noteworthy that not one of the children we have described with I Q above 130 has ever had any unusual amount or kind of home instruction. In most cases the parents were not aware of their very great superiority. Nor can we give the credit to the school or its methods. The school has in most cases been a deterrent to their progress, rather than a help. These children have been taught in classes with average and inferior children, like those described in the first part of this chapter. Their high I Q is only an index of their extraordinary cerebral endowment. This endowment is for life. There is not the remotest probability that any of these children will deteriorate to the average level of intelligence with the onset of maturity. Such an event would be no less a miracle (barring insanity) than the development of an imbecile into a successful lawyer or physician.
