Final answer:
The evidence from the Clarks' doll experiment, where 59% of children viewed the brown doll negatively, supports the claim that the experiment highlighted the harmful psychological effects of racism by showing internalized racial prejudice among African American children.
Step-by-step explanation:
The evidence that 59% said the brown doll looked 'bad' is relevant to the claim that the Clarks' doll experiment showed the negative impacts of racism because it supports the claim by demonstrating a biased perception of the brown doll, which is indicative of internalized racial prejudice. This experiment was instrumental in illustrating the psychological effects of segregation on African American children, with many children preferring the white doll over the brown doll and assigning positive attributes to it, highlighting a devaluation of their own racial identity. Furthermore, it suggests that these children had internalized negative societal attitudes towards their own race, which aligned with the Supreme Court's understanding in the Brown v. Board of Education decision that segregation was harmful and led to a sense of inferiority among African American students.
