Not done Sir, but doing.

"Kenneth B. Clark, a Panamanian African-American, obtained his Ph.D. under [Franz] Boas at Columbia in 1940.... Clark's testimony before the Supreme Court played an important role in determining the decision to force the racial integration of American schools in the landmark 1954 Brown vs Board of Education decision (347 US 483). Central to his testimony was his claim that because seven out of sixteen black children in an all-black school, when shown white and black dolls or drawings of such dolls, chose the white dolls as those "which looked most like them," segregation had "harmed the development of their personalities." The speciousness of his testimony was revealed by Ernest van den Haag, of New York University and the New School for Social Research, who showed from Clark's own data, collected in a study involving 253 black children from both segregated and nonsegregated schools, that a higher percentage (39%) of black children from racially integrated schools chose the white doll than did black children from segregated schools (29%) (Haag, 1960, Villanova Law Review). In other words, Clark had misled the Court with data that appeared to support his contention, while the data from his larger study showed the reverse of what he presented to the Court."
