" This research confirms a classic experiment from the 1960s conducted by a third-grade schoolteacher named Jane Elliott on her class in the small, all-white rural town of Riceville, Iowa. Elliott began her experiment by dividing her class into two groups by eye color—blue and brown—then presented the kids with examples of blue-eyed good people and brown-eyed bad people. In addition, the blue-eyed kids in the class were told that they were superior and were given special privileges, while the brown-eyed kids were called inferior and treated as second-class citizens.
