Indeed it does. The question of how good a measure IQ is is an interesting one.
Scores on Raven's progressive matrices certainly correlate well with all sorts of things (working memory, income, ability to do computer programming, ability to write a popular story), so I guess it depends in how you are defining "intelligence".
Do you have a source for this? I can find him saying it could be true (if it weren't for test scores influencing later worklife via people judging you for them) but not actually saying it is true.
