People who suffer from a rare genetic disorder called Williams Syndrome have a complete lack of social fear. They experience no anxiety or concerns about meeting new people or being put into any social situation, and a new study by Andreia Santos suggests that they also don't have any racial bias. From the article: "Typically, children start overtly gravitating towards their own ethnic groups from the tender age of three. Groups of people from all over the globe and all sorts of cultures show these biases. Even autistic children, who can have severe difficulties with social relationships, show signs of racial stereotypes. But Santos says that the Williams syndrome kids are the first group of humans devoid of such racial bias, although, as we’ll see, not everyone agrees."
