The experiment in this video was done before by psychologists Kenneth and Mamie Clark over 50 years ago. A group of children are put in front of a black doll and a white doll and asked a series of simple questions.
Sadly, the results are the same today.
Apparently 4 year olds already have it ingrained in their brain that black = bad and white = good. On average when questions were asked about which doll was pretty or nice 80 percent pointed towards the white doll.
