When I last took the test around 2009, I displayed a slight implicit bias towards European American faces. I don't hold explicitly prejudiced beliefs. While there is some connection between implicit prejudices and explicitly held attitudes and opinion formation (see the post IHaveCandy replied to), but it isn't necessarily the case as it is possible to be aware of one's implicit biases and reject them or for explicit values to be stronger, I guess.
But it isn't saying you're a sekrit racest.
I think this is where your perspective becomes incoherent. You are cognizant of race and you are categorizing them on the basis of race as soon as you become aware of that fact. You can attempt to abstract it - "I am not categorizing them by race; I am seeing that their skin color means other people would categorize them by race" - but this is ultimately a distinction without meaning.
And my point is that because of how our minds work, how we categorize based on visual information, how we live in a society that imparts information about racial categories (inaccurate though it is) that causes people make differing judgments on the basis of those racial observations, we are going to continue to have categorization on the basis of race (because race is visible and people make those categorizations automatically) and we are going to have racism (because we have had centuries of on-going judgments on the basis of race and those have consequences still today). For me, the solution is not to simply declare by fiat that race does not matter and that we do not see race. We do see race. When we act as if race doesn't matter we pretend that racial group differences in lifespans, wealth, educational attainment, income mobility, arrest rates, and so forth are not matters of systemic and institutionalized racism - racism doesn't matter; we're all just people! - but as matters that those people as individuals are wholly responsible for.
I really must insist that you read those books I recommended. Even if you don't agree with them, it will at least make this conversation better when we have it again.
