What is intelligence, anyway? When I was in the army, I received the kind of aptitude test that all soldiers took and, against a normal of 100, scored 160. No one at the base had ever seen a figure like that, and for two hours they made a big fuss over me. (It didn’t mean anything. The next day I was still a buck private with KP – kitchen police – as my highest duty.) All my life I’ve been registering scores like that, so that I have the complacent feeling that I’m highly intelligent, and I expect other people to think so too. Actually, though, don’t such scores simply mean that I am very good at answering the type of academic questions that are considered worthy of answers by people who make up the intelligence tests – people with intellectual bents similar to mine?
