Anecdote: I remember the business-related psychology class I took had a segment on the psychological impact of racism. It touched on the doll test as well as Jane Elliot's blue and brown eyes experiment, and how Black students perform more poorly when it's announced to them that their results will reflect their intellectual ability.
During the break, some non-Black students asked me if it was true. I just said it was. The same who asked me the question went on to say it was some liberal bullshyt and the fact that I was here (meaning in that specific school) proved it was not true.
