Earlier quoted context omitted.
Discrimination can't be "solved" because 1. People are genetically different and 2. Anyone can have biases about anything. I could shut down every interviewee with big ears, or beady eyes, if I wanted to. Again, all you can do is treat people as fairly as possible by basing admissions policies on merit and standardization, rather than sloppily basing them on perceived group identity.
I encourage you to teach a science course for non-majors at a local university that serves minorities. Unless you are intentionally blind the experience will be enlightening. The variation in quality of high schools in the US is astounding and needs to be experienced first-hand. Where does the talk about genetic variation and unconscious bias even come from? It's not relevant in this context.
I 100% realize that there is massive variation in high school quality. It doesn't astound me. [1]
What does that have to do with making college admissions fair and standardized?
