Ahh I see, I took a different test. I tried copying your link and instead it threw at me a sorting test related to black & white people in association with dangerous and non-dangerous objects, followed by a questionnaire.

Lol wtf?

Wait... now it's having me do your test, but with White and Japanese people.

This test is both garbage and strange, of course my results for the second set would be faster than the first once I've grown that much more used to the controls.
