This fascinating article from Dr. Susan Fiske at Princeton examines how the brain seems to rapidly categorize people we perceive into 4 categories. A kind neural baseline for empathy vs. prejudice. She even shows that some people are seem as non-human by the mind, but happily we can rehumanize people again. Worth a bit of a careful science paper read. Dense but not unreadable and just 4 pages long.
