In our population, which is now about 167 million, it is estimated there are more than 33

million people with I. Q. 's below 90; it is a disturbing thought that these people will never, at any age, read much more than comic books, newspaper headlines, and the simplest of best sellers, nor will they be able to make intelligent judgments on any complicated, important national or international problem. The intellectuals, of course, are at the other end of the scale, they are people with I. Q. 's of 130 or more, and there are slightly more than five million. From130 to the top of the scale, there are only 2.1 million people. Careful tests have shown that at least half of these high I.Q. people are never discovered, do not go to college, and live out their lives in humble, even though usually respected, occupations. The identified intellectual, therefore, will at best be only one person in 46, and is more likely to be one person in 150. It is not surprising that he feels a little queer, and is regarded by others as even more so.

The fact that there are divisions between groups along the I. Q. scale is an intricate matter. For one thing, the people at any given level show a curious tendency to disapprove of the mental activities of the people at every other level, above or below. The scorn of the highbrow when he sees a comic book reader is equal to the contempt of the vigorous, median-I. Q. foot ball player for the genius who pities oneself, reading poetry when he could be getting a good workout in the gym. It is a curious fact that high intelligence is rarely associated with the excess adrenal activity necessary for success in the hard, competitive world of business; the high brow comes rather low on the pecking order of humans. Each group sublimates its hostility, the intellectual often by writing something cutting about the businessman, the latter by driving a remarkably more expensive car than the former can afford.

A complicating factor is the rise of the mass media of communication--television, radio, the movies, and magazines with multimillion circulations. Many observers have pointed out that while all of these, to succeed, must be aimed at the median I. Q. , the creative efforts involved have to the made at a much higher level: this situation frequently stultifies the creative intelligence of those who earn their livings through mass communication.

Careful testing has revealed that, of the high-I. Q. people,______.

A．most go on to complete four years of college

B．many find their way into difficult professions

C．many are never discovered

D．many live out their lives in respectable occupations
