Are races real? Yes. Are they organized on some kind of natural ladder of superiority, where white people are on the top and black people are on the bottom, with others organized top to bottom by color of skin? ...No! Except in some people's imaginations! That's not only a silly idea, but also a psychotic one.

The IQ test is highly ethnocentric to what a white person living in a first world, western country would know. It would make no sense to try to create a hierarchy of races based on the IQ test.
