Because I'm asked this often: the idea of 'systemic racism' is (1) that racism - in some real sense of that term - is "embedded" within social systems like criminal justice or standardized testing, and (2) absolute evidence of this is that different groups perform differently.
The...obvious problem here is that the highest-performing groups in the USA are Koreans and Nigerians, not whites. Most gaps attributed to systemic racism vanish when basic regression adjustments are made for variables like age, region, test scores, and "father present."
(3) Every sane "center right quant" type AGREES past race/class conflict caused situational (poverty housing) and sometimes cultural (fatherlessness) variables that disadvantage Black and even poor white communities today. But, that's different from saying: "The SAT is racist!"
(4) The main difference between these two positions involves suggested solutions. Simply recognizing the top line to be true morally requires helping all poor people. Going beyond that to the "SAT" claim requires often-useless ghost-hunting for racism in modern left institutions.
