Same test. Leave the Hmong in Laos, uneducated. Are they superior?
Potentially? Unquestionably.
Yes, they are. And you know what? Their "culture" isn't technological in the least. They're best known for weaving beautiful rugs.
IQ tests can be given to people who are nonverbal, to people who can't function at all. The tests are "normed" so that cultural and environmental factors don't really play much of a role in determining the outcome.
Heck, Eskimos score very high on tests involving visual-spatial ability. No one knows why, really. Some suspect it may have something to do with all of the snow they've been staring at for thousands of years. :)
