Hmm, it said I have a moderate automatic preference towards European-Americans. An interesting test, to be sure; whether or not it actually says anything about someone being fundamentally racist, it certainly raises some interesting questions about how much we're really aware of our own reactions, and about the roots of those reactions. Despite a great deal of interracial integration in modern times, there's certainly enough residual racism present in media and in the activities and language of society to think that certain racist thoughts are still, consciously or not, bred into us from repeat exposure.
Another interesting, and related, study showed how black children tended (and apparently still do tend) to prefer white dolls over black dolls, ascribing more positive qualities ("nice", "good", "gentle", "beautiful") to white dolls and more negative qualities ("dirty", "bad", "ugly") to black dolls:

I've even observed the above effect when working with children; during a drawing activity, for example, black children were more likely to draw pictures of children with blond hair and fair skin than ones with brown skin and brown hair.
