Project Implicit - your unconscious will tell the truth (?)

I just finished reading the book Blink by Malcolm Gladwell. Tons of refreshing ideas, stories and experiments are introduced in the book. Among which is this Harvard project named IAT (Implicit Association Test): https://implicit.harvard.edu/implicit/demo/selectatest.html

Take the Race IAT for instance: You may never explicitly admit you are a racist. But this test is designed to show (and measure the degree to which) your brain finds it harder to categorize stuffs when what represents good is on the same side with black people, than doing so when good is paired with white. In other words, your unconscious does not accept black as naturally as white. Give it a try, and the result may surprise you.

I think the design of this test is scientifically sound. Everything else being equal, the only factor that would affect our responding speed is how closely two elements are connected in your subconsciousness. When it comes to explaining the results, I agree with Gladwell. Even though as rational, thoughtful and educated human beings we know and believe racism is incorrect, part of our unconscious is shaped by the mass media and social stereotypes, which are still racist, discriminating and biased in one way or another. I do accept the fact that, as the IAT revealed, my brain has moderate racist and anti-homosexual tendencies. But I think it is generally constructive to admit the existence of such unconsciousness. This is why I recommend more people do this test.

P.S.

My own favorite is the Gender-Science IAT. Results showed that I almost completely associate science/engineering with guys, and consider subjects like history, philosophy and arts a great deal more feminine.. This one is true on both conscious and unconscious level, though. I do not consider it a politically incorrect position, and I'm not ashamed to admit. :S
