I have studied social experiments in my undergraduate education but never came across this study. It was interesting how quickly the confirmation/association bias was enacted by the children. "She's a brown-eyed person" as a reason to be slowly getting to the material. As if that was the reason for the student’s lack of hastiness to get to the correct page. (~3:40) "Brown-eyed people may not go back for seconds"... "they are not smart" (~4:20) There was no bases of this assumption, except for the color of their eyes. The teacher is this experiment noted that she watched young students turned into "nasty" 3rd graders in the matter of a day. Imagine a childhood filled with this information and the deep rooter conditioning that people experience.
