Has anyone else seen ? (The link is the first one of a set of video clips of a longer documentary.)
It's documentary about an "experiment" (the woman who designed it, Jane Elliott, prefers to call it an "exercise") that examines privilege and otherness. Jane Elliott was an elementary school teacher in the US in the 1960s and did this exercise with the children in her class to get them to think about racism.
The teacher segregates the children according to whether they have brown eyes or blue eyes, giving (at first) the blue-eyed children special, arbitrary, privileges. The blue-eyed children are very quick to defend their privilege, and the brown-eyed children very quickly become demoralised. (Later, she reverses the situation so the children can experience the opposite situation.)
The relevance to racism is obvious, but I think it's really interesting to look at it from the perspective of sex discrimination as well. What I thought was interesting was the way in which the blue-eyed children tried to justify their privilege - they seemed to need to justify it in terms of the inferiority of the brown-eyed children, in order to be able to live with and enjoy it.
