when i was about 12 i saw a televised report on The Doll Study among other studies on racism. That study made a huge impact on me and my concept of race and racism. In it they asked a bunch of, like, 5 or 6 year old black children which baby dolls were prettier, and i think things like which could be trusted etc, and it turned out the overall trend was for the children to pick the light-skinned dolls over the dark-skinned dolls for positive traits like "prettier" -- even though they were themselves black, living with black families.
Because they were exposed to television shows and movies and classrooms and commercials and kids books and radio, because they lived in a society that codes light for good and dark for bad AND still contains many things that code for the same in specific association with skin color... these little black kids pointed to the white dolls and said they were prettier and ascribed other positive traits to the dolls with lighter skin over those with darker skin.
That study was originally done by the Clarks in the 40's, and i think the report was on a reprisal of it in maybe the 80's. More recently Toni Sturdivant, an assistant professor at East Texas A&M University (a public research university) did a similar study, like three or four years ago i think, with similar results.
It is so important that we work to remove these kinds of biases, and if we want to talk about the light of day being safe and the dark of night being scary or whatever, then maybe eventually different language, new words created or old words given new life, should be employed to differentiate when we are talking about pigment or light, so we can remove the assignment of "scary" to "dark" the way those things conflate currently
it's so sad that little children are kind of, like, learning to hate themselves? just through the passive absorption of this culture? surely we must try our best to change that.
