I remember seeing a study a couple of years ago where they tested different methods of teaching math to to find one that reduced demographic differences.

They colcluded that some specific order of teaching concepts worked best, and recommended it.

You'd have to dive down and look at the data to see that the new pedagogic paradigm succeeded by making the material confusing, and equity had been achieved by reducing everyones scores but reducing the scores of the best students the most dramatically.

Deep down they must know that differences in outcomes are biological in nature, and that there is nothing they can do to erase them besides sabotage.
