My opinion, based on the other research that these tests have spawned, is that it proves that people can engage in prejudiced behavior unconsciously, without being aware they are doing it, regardless of their consciously held racial biases or anitbiases.
To cite a couple examples.
From Blink: studies measured subjects’ scores on basic academic tests (I think they were math tests.) Black students scored significantly poorer than white students when and only when they were asked to identify their ethnicity at the beginning of the exam. This suggests that just the very simple reminder that they were black was enough to undermine performance on the exam.
Another study my husband told me about (he actually knows way more about this stuff than I do) went as follows. People were paired in various black / white combinations and each told to conduct interviews of the other–the interviewee was then scored on performance by a panel of judges. By and large the white people being interviewed and the black people being interviewed by other black people scored substantially better than black people interviewed by white people. Scientists observed that when white people, even those without any overt racial bias, interviewed the black people, they tended to sit much closer to the black subject and interrupt them more often. To continue with the experiment, scientists did it over again, this time requiring all interviewers to sit at that same up-close distance-- the result was that with that extra change in distance, the white interviewees performance dropped just as markedly as the black interviewees had.
And then there are the many observational studies and experiments where it has been shown that even people with no overt racial biases consistently discriminate in unconscious ways – not calling job applicants with “ehtnic” names, or offering as good a deal on everything from car rentals to bank loans.
So I think these tests do have a lot to say – and are corroborated by a ton of other evidence – about unconscious cultural and racial bias in this country. The problem is people think “unconscious racial bias” means the same thing as “racist.” It’s doesn’t. All it really means is that, if you score as having a bias against blacks, you’ve just been given more messages and images that are negative than are positive. It’s a numbers thing. It’s about cultural exposure. For IATs there is little correlation between the person’s most deeply held beliefs about racism and how they score on the test. It doesn’t measure whether you’re a jackass. It measures whether in your lifetime you’ve by and large been exposed to negative images of black people-- and it does affect behavior that is beyond conscious control.
A good example is me. I’m not a racist. Racism offends me. Racism is the scourge of my existence. I hate it. HATE it. But I scored as a moderate bias on one of these tests. Does that prove I’m really a racist? No. It’s explainable by the fact that I grew up in a racist shit hole and see racist images and hear racist opinions all the damn time.
I also took a test on gender bias – how well I correlated science and math with men and English and the arts with women. You know what? I scored with having a bias TOWARDS women being associated with math and science–it’s easier for me to associate women with math and science. The most likely explanation for this is that my mother is an Engineer, my Aunt was a biology major in college, I considered going into biology myself and most of my friends at the time I took the test were female engineers.
So please, whatever you do, understand it’s not intended as a judgment on your moral beliefs or opinions. It’s intended as an analysis of overarching cultural trends and messages and how the unconscious mind uses those messages, regardless of our moral beliefs, to impact our unconscious behavior.
That is all.
