I will agree that western designed tests show that westerners do well at western institutions. Nearly any time someone creates a metric of something as difficult to define as intelligence, they create it in such a way that they're the top scorers. I'm sure if those living in sub-saharan africa were to design their own intelligence tests, it would favor them instead.
Except for some weird reason, those eastern orientals seem to do very well on these western tests of intelligence, even though they learn English as a second language! So much so that western universities are flooded with them and the administrators of the western universities are restricting oriental student numbers while handing out affirmative action slots to blacks.
Doesn't it strike you as odd that first generation immigrant oriental children score higher on the English (verbal) portion of the SATs than African-American children, whose families have been speaking English natively for umpteen generations? Or were these tests created specifically to favor western AND eastern students while somehow excluding blacks? (that would be quite a trick)
