Although I understand the desire to scrub race from applications, if a candidate has overcome some form of discrimination, that isn't something we should necessarily just write off or actively ignore. Acknowledging the unfair treatment they may have received in life helps level the playing field.
That would be one way to remove bias from the process.
I've often thought college admissions should be done in a blind manner. Applications go to a subcommittee that removes all race/gender clues from it, then the scrubbed applications go to the admissions committee.
