Several studies have shown that whites attribute supernatural, extrasensory and magical mental and physical qualities to blacks. Black children are often seen as years older than their actual age.

According to a new study by the American Psychological Association, Black children from the ages of 10 are seen as older and less innocent than their White peers.
‘With the average age overestimation for black boys exceeding four-and-a-half years, in some cases, black children may be viewed as adults when they are just 13 years old.’
What does this mean?
It means that Black children are often perceived to be guilty and face police violence if accused of a crime.
“‘The study, published in the Journal of Personality and Social Psychology, sought to examine the extent to which the racial bias exists and how significant the consequences are. Speaking on the report, Phillip Atiba Goff, PhD, explained, ‘Children in most societies are considered to be in a distinct group with characteristics, such as innocence and the need for protection. Our research found that Black boys can be seen as responsible for their actions at an age when White boys still benefit from the assumption that children are essentially innocent.’”
