This is why most standardized tests don't necessarily give an accurate assessment of intelligence. They might, for some people. But they're every bit as likely not to miss the mark when it comes to others. The pool of testees doesn't have to be very large before there'll be someone the test is biased against, just because of the diversity of our experience.

BTW, since we're divulging, mine was 140 - but it was a high-school level test administered to me when I was in my 20s, so it really means nothing.
