I'd be curious to see how the data varies across time and societies/cultures. Google returns nothing.
Keep in mind: The doll experiments were first run in 1938. They predate the Stanford prison experiment by 30 years, the Milgram experiments by more. At the time, Amos'n'Andy were prime-time radio, the pickaninny in Fantasia was two years away, The Jazz Singer was less than ten years previously and Jackie Robinson wouldn't take first base for another nine years. Studies in race were larval at best - we'd traded the White Man's Burden for eugenics and a lot of shit learned in that era needed to be relearned. The issues aren't necessarily as simple as they are portrayed but to systematically dismiss the outcomes speaks a lot more to the unsophisticated nature of the critic than it does the methods of the study. Ahem.
