Blacks very commonly assume when white people do something mean to them they're doing it because they're racist. Sometimes of course this is true, but if there is statistical evidence contradicting the idea that there is a general trend of such behavior, it is an absurd, narcissistic assumption to make. My German grandmother's been ticketed for driving too slow, by a black cop no less. Was he being racist? This metanalysis finds that when making value judgements, blacks exhibit a statistically significant bias in favor of their own race. White people on the other hand, exhibit a very small bias in favor of... blacks. It would make sense for blacks to think whites were racist towards them. After all, whites have a lower opinion of them than they themselves have. The problem is that the whites are, at worst, judging you fairly, and to an extent giving you the benefit of the doubt.
You might say this just reflects the general population, and blacks in the justice system might still be discriminated against. Well, Mitchell 2005 finds the same pattern of black in-group bias and White biaslessness in jury verdicts.
Given the sheer mass of "lived experience" i'm arguing against here, no doubt a lot of the resistance to these statistics boils down to "can every black person just be wrong?" Well, here's an interesting experiment on perception of discrimination. Subjects were given prosthetic deformities, then put into conversation with another person. Afterwards, the experimenters asked if they felt had been discriminated against on the grounds of their appearance. The subjects said yes, and were then shown that before they met with their conversation partner, the prosthesis had been removed. Clearly, they were engaging in narcissistic armchair psychology. Given the fact that some whites actually are racist and do do racist things regardless of any *net* discrimination, such a belief is harder to shake outside of a controlled environment.
