As can be clearly seen in the passage, racial prejudice —.

Nowadays, we all like to think we have got past the racist nonsense of previous centuries, when even the most eminent scientists, white ones, of course, declared white people to be the pinnacle of human progress and other races to be inferior. We now accept that no race is superior to another. There is no question that most societies have made enormous progress in eliminating such overt racial prejudice. But an unsettling study published by researchers in the United States suggests that there is still a long way to go. Even today, the study finds, Americans of various races still unconsciously dehumanize their black fellow citizens by subtly associating them with apes. In an experiment in which students were subliminally flashed a photo of either an African-American or a European-American face, and then shown a blurry picture of an ape, those shown the black face were quicker to recognize the ape. More troubling still, this association is not just confined to psychologists' tests: it also appears to bias people's judgements about whether specific instances of police violence are justified.
