I wish you were right, because if the issue was just a few racist admissions officers, then the solution would be simple: fire them and get non-racist ones, problem solved. However, there is a fourth, more likely explanation:
4) Harvard's scoring is unintentionally hurting Asian students.
From the article, it seems that Harvard focuses on establishing student diversity that roughly tracks the US population, bringing in big money donors, bringing in legacy students, and finding leaders that have traits similar to other successful leaders in the past.
None of these values have the intent to reduce Asian admission, but that is their undeniable effect.
It means that Asian students don't face a single racist admissions officer, they face a facially race-neutral system that has a discriminatory effect. To fix it, you can't just fire a few people, you need to make much larger changes. My original point was that the only fair and effective solution would need to require a larger class size.
