“For example, the fact that school is boring, arduous, and full of busywork might hinder students’ ability to learn. But to the extent that school is primarily about credentialing, its goal is to separate the wheat (good future worker bees) from the chaff (slackers, daydreamers, etc.). And if school were easy or fun, it wouldn’t serve this function very well. If there were a way to fast-forward all the learning (and retention) that actually takes place in school—for example, by giving students a magic pill that taught them everything in an instant—we would still need to subject them to boring lectures and nitpicky tests in order to credential them.”
