[ExI] iq misconception

[William Flynn Wallace]

(In response to a passing remark made today)

This battle has been going on for many decades:  is intelligence just one
thing, generally called g, or is it several several things?

The vast majority of studies support the g concept.  It's simply a matter
of prediction, which is the main thing you want a test to do.  Whatever
test predicts the best is the best, and the Binet-Simon and Weschler tests
are unsurpassed.

This is all assuming that factor analysis is a valid technique, which some
dispute.

Yes, there are different skills - some drawing heavily on g, and some not
at all, like musical ability.
