Were Jane Elliott"s "Brown Eyes/Blue Eyes" Lessons Successful?

Jane Elliott was an early pioneer in "Diversity Training" in the mid-to-latter 20th Century. There have been "diverse" opinions regarding the ethics of her initially using elementary school children for her lessons and generally how effective they have been. My main take-away is that the lessons exposed how hard it is to change people's attitudes toward "The Other." The link below gives details on what she did and the results.  This link is the result of a general Google search on her.
