I just took the "Decision 2012" IAT. It was quite interesting. According to this I have a moderate implicit preference for Mitt Romney compared to Barack Obama. I also have a slight implicit preference for White People compared to Black People. I will admit that I prefer Mitt Romney to Barack Obama. Race is no issue there, I prefer Mitt Romney's political views, I'll be honest. Now, to address the other thing. I am certainly not consciously racist, but it is true that I hold certain stereotypes. I don't believe in them and I don't attempt to act on them, but they are still there. Subconsciously, I hold a few stereotypes of other races. I'm sure that not every person falls victim to this, but many do. I think this implicit preference doesn't really mean much. I did answer on the "hot to cold" scale, that white people are slightly warmer to me than black people. I think I answered an 8 for black people and 9 for white people. I grew up in suburban St. Louis. While I was around lots of black people growing up, most of my friends outside of school were white. I lived in an area that is 98.19% white and 0.07% black. There were a lot of black people that I went to school with because of a desegregation program in which my school would bus kids in from the inner city, so I felt very comfortable around black people, but I suppose I do feel slightly more comfortable around white people, because that is who I grew up around.
Anyway, here's a meme that applies:
