From 1950-2007, broadly-defined, malleable social science evidence presented in school desegregation cases in the Supreme Court impacted the Court's opinions. In McLaurin v. Oklahoma State Regents (1950) and Brown v. Board of Education (1954), the Court sided with evidence that showed the psychological harms of segregation. But with new emphasis on educational benefits of integration in Parents Involved in Community Schools v. Seattle School District (2007), the Court seemed less persuaded by social science evidence.
