I did not include more detailed reasons (question bias, etc.) but I did at least try to point out the discrepancy. And the later statistics linked show that the discrepancy between white and Native American students’ average test scores is only 91 points, not the full 150.
Out of curiosity, I also checked the income boosts. The difference between the lowest and highest income bracket is only about 100 points. I don’t know how that difference compares in percentiles based on income, but I dont think context considerations are having a very big impact on test scores in admissions.
