Karin Chenoweth takes on Charles Murray’s educational determinism on Britannica Blog.
For one thing, people have genetic limitations, but in most cases no one really knows exactly what they are, what they limit, or how to measure those limitations â€” in part because the human brain has the capacity to compensate for those limitations in surprising ways. Which raises the question: What sorting mechanism would be sufficient for this purpose? How reliable is it? Couldnâ€™t there possibly be children who should go to college despite scoring low on whatever first-grade measure we allow Murray to choose?
Good instruction makes a huge difference, Chenoweth argues.
