THE HEREDITARIAN THEORY OF IQ
men who are not working, and saying, "Do it, do it, hurry up, quick." At
the end of 2 minutes examiner says, "Stop! Turn over the page to test 2."
The examiner demonstrated test 2, cube counting, with three-
dimensional models (my son had some left over from his baby
days). Note that recruits who could not write numbers would
receive scores of zero even if they counted all the cubes correctly.
Test 3, the X-O series, will be recognized by nearly everyone today
as the pictorial version of "what is the next number in the
sequence." Test 4, digit symbols, required the translation of nine
digits into corresponding symbols. It looks easy enough, but the
test itself included ninety items and could hardly be finished by
anybody in the two minutes allotted. A man who couldn't write
numbers was faced with two sets of unfamiliar symbols and suf-
fered a severe additional disadvantage. Test 5, number checking,
asked men to compare numerical sequences, up to eleven digits in
length, in two parallel columns. If items on the same line were
identical in the two columns, recruits were instructed (by gestures)
to write an X next to the item. Fifty sequences occupied three min-
utes, and few recruits could finish. Again, an inability to write or
recognize numbers would make the task virtually impossible.
Test 6, pictorial completion, is Beta's visual analogue of Alpha's
multiple-choice examination for testing innate intelligence by ask-
ing recruits about commercial products, famous sporting or film
stars, or the primary industries of various cities and states. Its
instructions are worth repeating:
"This is test 6 here. Look. A lot of pictures." After everyone has found
the place, "Now watch." Examiner points to hand and says to demonstra-
tor, "Fix it." Demonstrator does nothing, but looks puzzled. Examiner
points to the picture of the hand, and then to the place where the finger is
missing and says to demonstrator, "Fix it; fix it." Demonstrator then draws
in finger. Examiner says, "That's right." Examiner then points to fish and
place for eye and says, "Fix it." After demonstrator has drawn missing eye,
examiner points to each of the four remaining drawings and says, "Fix
them all." Demonstrator works samples out slowly and with apparent
effort. When the samples are finished examiner says, "All right. Go ahead.
Hurry up!" During the course of this test the orderlies walk around the
room and locate individuals who are doing nothing, point to their pages
and say, "Fix it. Fix them," trying to set everyone working. At the end of
3 minutes examiner says, "Stop! But don't turn over the page."
