Why the supreme court changes their mind from time like plessy v Ferguson to brown v board of education?

The Supreme Court's shift from Plessy v. Ferguson to Brown v. Board of Education reflects changing societal values and a growing understanding of racial equality. Over time, increasing evidence of the detrimental effects of segregation and the Civil Rights Movement's advocacy for equal rights influenced public opinion and legal perspectives. Brown v. Board recognized that "separate but equal" was inherently unequal, marking a significant shift in constitutional interpretation and emphasizing the importance of social justice. This evolution illustrates how the Court can adapt to new societal norms and principles.
