Final answer:
The landmark 1954 Brown v. Board of Education decision declared that segregation in public schools was unconstitutional and a separate but equal education was not possible. The Supreme Court incorporated insights from scientific research on the effects of segregation, which suggested that racial discrimination led to feelings of inferiority among Black children.
Step-by-step explanation:
The landmark court decision of the judicial phase of the civil rights movement settled the Brown v. Board of Education case in 1954.
In this case, the Supreme Court unanimously overturned its decision in Plessy v. Ferguson as it pertained to public education, stating that a separate but equal education was a logical impossibility.
Even with the same funding and equivalent facilities, a segregated school could not have the same teachers or environment as the equivalent school for another race.
The court also rested its decision in part on social science studies suggesting that racial discrimination led to feelings of inferiority among Black children. The only way to dispel this sense of inferiority was to end segregation and integrate public schools.
