SOMETIMES POLITICAL fights go on long after evidence that should settle the argument has come in. Such is the case with standardised tests.

The Biden administration took the opposite stance: it encouraged colleges to consider dropping admissions tests like the SAT or ACT, which critics have long said favour the wealthy and disadvantage black Americans. In 2020, which already seems like another era, Ibram X. Kendi, author of “How to Be an Antiracist”, called the tests “the most effective racist weapon ever devised to…exclude [black and brown students] from prestigious schools.”
