I was shocked at how quickly the children in this video accepted the teacher's words as truth and began to act on them. To me, this demonstrated just how much power and influence adults have in a child's life, and how easily bias is transmitted generation to generation. I can remember my white grandpa, born in the south to immigrant parents, making intensely racist comments and no one standing up to him. I remember my dad making less overt comments, but were racist nonetheless. I remember my mom ushering us away when there was a "scary" black man nearby, and reminding us to always lock the doors and keep our heads on a swivel when we went downtown. All of this, in combination with growing up in a nearly all-white community, have contributed to my biases. Despite my own belief that I am "good" and "not a racist," I clearly have work to do.
I hope the lesson from the experiment stuck with the children in a meaningful way, but I suspect that there were other influences in their lives that had stronger sway, such as parents, relatives, and other teachers who weren't as open-minded.
