ABSTRACT
DURING the last two or three decades the use of intelligence tests has spread with a rapidity that would have seemed incredible fifty years ago. It is therefore not surprising that many people have begun to ask how far the evidence really justifies these widespread applications. Some of the more vigorous criticisms have come from psychologists themselves. Unfortunately, however, neither critics nor supporters seem to have a very clear notion of what intelligence implies or what are the limitations to which the tests in current use are subject.
