Despite the overwhelming evidence that mitigates against the use of pr
ofile analysis, the practice of diagnosing specific cognitive or proce
ssing disabilities continues. The reason that profile analysis remains
popular is probably because school psychologists are simply unfamilia
r with the literature. They have a difficult time understanding the no
tion of g, along with its implications. Generally, the users of profil
e analysis assume that because the IQ tests, particularly the WISC sca
les, generate scores from subtests that differ in content, they must b
e measuring different types of cognitive abilities, and therefore the
profile of these cognitive abilities should be diagnostically importan
t. Finally, they find profile analysis more socially acceptable in tha
t it implies the existence of multiple intelligences. The notion that
a single IQ score captures all that is meaningful and practical about
the IQ test is simply not acceptable, regardless of evidence to the co
ntrary.
