Actually, IQ tests were originally developed to measure the "intelligence"
of army recruits to determine what area they were most suited
for. The story
is long and somewhat convoluted as to how it became a measure of something
that we can't even agree what it is.
By the way, I'm a high school teacher who doesn't use a text. I guess my
students do OK at the college level, but I sure work way to hard. I'd like
to see a well written text with appropriate problems to solve and lots of
conceptual type questions. Oh well, I guess I'll have to writ one
of my own.

I think that is right, as I read that IQ was originally
success in school. One of the big fallacies about IQ is thatit is fixed.
The research of Feuerstein has shown that it is possible to dramaticallytreatments that
change IQ, even starting as late as age 15. If the sort of
are useful in changing thinking level were generally available,the effect
of SES (Socioeconomic Status) might be lessened.status, english

I thought IQ tests were a good predictor of college success --
that's how they're
designed. The problem is they're misnamed. i.e. that's all they do.
(indirectly [concomitantly] they may measure socio-econ,
after readingcomprehension, etc., but not I.Q. -- unless I.Q. is another
phrase meaning the
former.)

P.s. What's SES?

It is not PC to mention it, but an important predictor of

This measure is designed to be normally distributed.
A high school may expect to see student results in

[i.e. transformed to a normal distribution] for this reason alone.
