Incorrect. The whole point behind the Brown vs. Board of Education was to destroy the Jim Crow system of Education in the south. To do that, the Supreme court based their decision on dubious research that "proved" that black students could not do well in school unless they were in the classroom with white kids. I'm not joking...you can look it up.
Given this "scientific" underpinning, it was perfectly natural to see bussing presented as a remedial tool.
Naturally, the "findings" of the "studies" that served as the "rational" basis for an emotional decision concerning a bad situation have never been able to be duplicated. As Thomas Sowell noted when discussing this case, it's an old legal maxim that "Hard Cases Make Bad Law".
