- And vocabulary is one of the best single indicators of intelligence,
- according to a number of studies. Some IQ tests are 100% vocabulary
- tests, including some of the tests Terman used in his famous
- longitudinal IQ study. One frequently cited reason is that a person's
- vocabulary is an indirect measure of the ability to learn new meanings
- in context.
-
- Antonyms and word analogies make up only 53% of the verbal SAT; the rest
- is made up of sentence completions and reading comprehension. Here are
- the 15 stems from the antonym section of an old SAT: FRET, DISHEARTEN,
- LUXURIANT, HINDRANCE, INANIMATE, ANONYMOUS, ATYPICAL, CONCEIT, RANT,
- WOODEN, ACQUIESCE, ADROIT, MUNIFICENT, UNDERSTATE, VIRULENT. It's a
- common myth, especially among poorly prepared high school students, that
- SAT vocabulary words are mostly obscure relics from dusty, unabridged
- dictionaries. That's absolutely not true, as the above list clearly
- shows. A student scoring around 350 on the verbal SAT would probably
- have chosen the correct antonyms for only about 4 of the above 15 words
- (approximately the national high school average). Put that person in an
- advanced college course with students who had no trouble with 14 out of
- the 15 words (about 750 verbal SAT level) and I think it's likely he'd
- have a bit of trouble. I suppose you'd say, Eric, that it wouldn't make
- much difference? And keep in mind that this vast score difference would
- also necessarily indicate a huge disparity in ability on the sentence
- completion and reading comprehension sections.
-
- If you meant to say that differences between scores like 650 and 580
- don't mean much, I'd agree with you. But no difference between 340 and
- 710? Sorry, I disagree.
-
- >In addition to this, the questions on SAT have often several correct
- >answers.
-
- Often? Absolutely not. I included an example of an ambiguous
- item from the verbal SAT a while ago to show that you sometimes
- can't get an 800, no matter how "smart" you are. But such items
- are relatively rare. They certainly aren't common enough to
- cause the kind of unreliability you seem to be suggesting.

- You've got me interested - I'll have to take a look at it.
