" There are, in fact, some people who do not appear to have a built-in preference for their own race. They suffer from something called Williams Syndrome, and lack the usual fear of strangers and the unknown. Researchers at the Central Institute of Mental health in Mannheim, Germany, found that normal white children, aged five to seven, matched good characteristics with photographs of people of their own race and negative characteristics with people of other races. Twenty children with Williams Syndrome did not, matching characteristics without regard to race.
The syndrome appears to change the way the amygdalae communicate with the pre-frontal cortex, and it eliminates social inhibition. People with Williams Syndrome are “hypersocial,” and do not see danger in the faces of people who may be threats. They also tend to be mildly retarded and to suffer from other physical complications.
