Those who promote such sperm banks, as well as those who buy their services in order to produce child geniuses, are misinformed. For instance, Graham himself reports that 70% of the population possesses mediocre intelligence or less. He should take a course in statistics. If * mediocre* is defined in terms of the population mean plus the standard deviation times some unspecified factor, it should not be surprising that 70% of the population is of mediocre intelligence. This would be true even if the mean were an IQ of 200. The statement ranks right up there with a speaker in a radio broadcast a few years back, who pronounced with alarm that 50% of the population is of below-average IQ.
