- Vocabulary correlates fairly well with a range of other abilities.
- That's a fact, even if it's not clear why.

- Fair enough, but you should know you're disagreeing with some of
- the foremost researchers of human intelligence today.

- Yeah, but, as I'm sure you realize, it's a sampling test. If the SAT
- vocab pool consists of 60,000 words, each of the 15 sample words is
- worth 4,000 words in the estimate, not just one word.

- That's very unlikely because the SAT tests only fairly commonly used
- words, leaving out only the kind of words which you obviously know if
- you were able to read the instructions on the test. In fact, I found
- about half of the 15 words (the SAT words I listed in a recent post) in
- a dictionary for grades 3-6, containing a total of 36,000 entries. So,
- what you're saying is that someone might have a vocabulary of 1 million
- words, yet know virtually none of the words in a grade school
- dictionary??
-
- I think you have a point if you're talking about trying to score near
- 800 on the verbal SAT. That requires a virtually perfect command of
- the SAT vocabulary pool. I just think it's very unlikely that someone
- could have a very large vocabulary above the SAT range without a
- reasonably good coverage within the SAT range.

- The same could be said of each of the many other skills which
- add up to what we think of as intelligence.

-
- Exactly. It *may* indicate that, but usually it doesn't.
- That's what a less-then-perfect correlation means.
