These are among the thorny questions emerging in online forums in Mexico since a government agency began circulating a "viral video" showing schoolchildren in a taped social experiment on race.
The kids are seated at a table before a white doll and a black doll, and are asked to pick the "good doll" or the doll that most resembled them. The children, mostly brown-skinned, almost uniformly say the white doll was better or most resembled them.
One child in the video with mixed-race features says the white doll resembled him "in the ears."
