If anyone is interested, this is a cool site with a lot of different quizzes that will help evaluate your implicit biases.

Entirely tangential story, but at this point I don't think this thread has a point so i'm fine with it. If you don't feel like reading two unrelated stories on race perception, just skip this post. That said:
Back when I was in college, that site got me in trouble with some of my peers. Keep in mind I went to a school known for it's theater program (so very liberal), that was also a private school on the more expensive side, in the Northeast US (so very white).
To my knowledge, I was one of, if not the only, minority in one psych class-but I look very white, and have a white last name. My friends were mostly not in the psychology major, so none of the people in the class knew I'm mixed. I also grew up idolozing my older cousins who lived with me when I was a kid, who were black & hispanic mixed, and by chance my other main role models were all POC. I do have biases as a result, as do we all, which I'm aware of and try not effect my general behavior/attitudes. All that's just some background for what comes next.
In one of my psychology classes, we were asked to take a race (white/black) test, and share our results. Pretty much everyone in my class assumed they would come back as having no biases (despite us already learning that's not how it works), and were shocked when everyone came back with an implicit bias towards black people/against white people. Except me, which they at first made them assume I was lying. Then when they saw the results (I think we had to print them out), someone accused me of cheating the test by purposefully waiting longer on certain ones, or taking it multiple times. Caused a huge argument with like 3 of my classmates, which ended up everyone calling my racist against white people.
My guess is that they couldn't accept someone wasn't implicitly racist against black people, or at least it wasn't them. I don't think I ever explained to them my race/personal context, as it's not there business.
A similar thing happened in a different class, with many of the same people. A professor was talking about bias, and asked us which of the two people would be on our radar for stealing. One was an old white man in a hoodie, the other was a young black man with 'typical black clothing' (i forget exactly what). The point of the discussion was how systemically we are taught to discriminate against certain types of people and assume their shoplifting with no evidence, while ignoring others.
Each year at B&N, I had to complete a loss prevention program, where they went over what to watch out for, how to react, how to submit claims, where to post known shoplifters, etc. One of the big thing is who to watch out for as a shoplifter. The primary suspects are middle aged individuals as they're the most frequent shoplifters. And people wearing either backpacks/bigger-than-needed bags, or baggy clothes. And people wearing hoodies, with the hood up. So the first guy would have been on my radar, per what the 'system' said, while the other guy would not. I shared that after the entire class was discussing how horrible the racism is in this regard, but not discussing any personal experiences, or statistics. They all again accused me of lying, misunderstanding, or claiming that barnes and noble was an anomaly for some unknown reason. None suggested further research into it, including (I think) the professor who just had us move on.
It was all really bizarre, and did a bit to teach me about the ways people aren't willing to examine their own biases.
