Well, when I was doing my own degree in psychology 30 years ago,
those of us in the testing and metrics courses were acutely aware
of the issues of cultural biases in testing and working very hard
to eliminate them and to be able to demonstrate that they'd been
eliminated. That's why the 'stupid people' who produce the Stanford-
Binet IQ test, for example, have revised it 5 times. And why the
'stupid people' who put together the Scholastic Aptitude Test are
continually refining it.
