JohnSpotter saidWell, that was disturbing.
I agree with aMoonHawk though. They needed to mix it up more. I would have liked to have seen how the children reacted to a blue and a yellow doll or if their opinions changed quickly if a lighter puppet hit a darker puppet.
Also, some of the children should have been asked first, "Do you think the dolls are both just as pretty?"
Some of the children looked like they were trying to give the answer that was expected, not necessarily what they felt themselves.
For the ones who like to question the methodology of the study, you can read here about the study:
Also, you can learn about the research methodologies by reading online or taking a course. For example, you don't set the question with a bias as suggested above like "Don't you think they are both pretty regardless of race?!" The goal is to study the perception of these kids of race, not to educate them. In a more recent study that CNN reported, the older kids gave the answer that most of us like to hear: "They are all equal, teachers like them equally." The older kids give the answers that they think is the right answer, but kids of 3-4 yr old simply reflect their emotional perception.
Several studies with different questions have been performed and they all got the same results. Denying a problem doesn't solve it, looking away when you see a disturbing reality might be the easiest reaction, it definitely isn't the solution.
