The lavish attention devoted to intelligence (raising it, praising it, worrying when it is low, etc.) seems wasteful in light of the fact that we choose to virtually ignore another set of mental skills with just as much social consequence—rational thinking mindware and procedures. Popular books tell parents how to raise more intelligent children, educational psychology textbooks discuss the raising of students’ intelligence, and we feel reassured when hearing that a particular disability does not impair intelligence. There is no corresponding concern on the part of parents that their children grow into rational beings, no corresponding concern on the part of schools that their students reason judiciously, and no corresponding recognition that intelligence is useless to a child unable to adapt to the world.
