"The students were also shown photographs alongside descriptions of various crimes and asked to assess the age and innocence of white, black or Latino boys ages 10 to 17. The students overestimated the age of blacks by an average of years and found them more culpable than whites or Latinos, particularly when the boys were matched with serious crimes, the study found. Researchers used questionnaires to assess the participants' prejudice and dehumanization of blacks. They found that participants who implicitly associated blacks with apes thought the black children were older and less innocent."
BTW: There’s plenty of solid information available to demonstrate that, when matched for SES status, public schools (across the nation) are “higher performing” than private schools, if only because the programs at public schools, if they are in affluent areas, tend to be much richer than typically smaller private schools can offer. Exclusive private schools do offer an opportunity for kids to hob-nob with other kids from wealthy families which does offer some employment advantages. It obviously doesn’t offer a chance to learn to deal with a diverse population, but with the US’s increasing levels of economic segregation that likely would not hurt the wealthy too much. Just raise the fences around the gated-communities a little higher and hire a few more security guards. Doesn’t do much for the rest of the US proletariat, though.
