The Doll video! Next up, the Implicit Test.
We need more than two examples of internalized racism.
Not to play the inappropriate stickler, but is there any possibility that young children see this difference as stemming from the treatment they receive from adults? White adults, in a hyper-PC world, treat young black children as pleasantly as possible, not daring to scold another person's child (especially one of another race) whereas they are scolded by people within their own community, who are more likely to be black? They may similarly see reticence on the part of their own parents to scold white children, and therefore unless they are privy to white children being scolded by their white parents, have a limited frame of reference. I can't imagine a white parallel experience, so this seems pretty unlikely, but maybe.
