Asimov has a great article called “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.
…
All my life I’ve been registering scores like that, so I have the complacent feeling that I’m highly intelligent, and I expect other people 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 test – people with intellectual bents similar to mine?
For instance, I had an auto-repair man once, who, on these intelligence tests, could not possibly have scored more than 80, by my estimate. I always took it for granted that I was far more intelligent than he was.
Yet, when anything went wrong with my car I hastened to him with it, watched him anxiously as he explored its vitals, and listened to his pronouncements as though they were divine oracles – and he always fixed my car.
Well, then, suppose my auto-repair man devised questions for an intelligence test.
Or suppose a carpenter did, or a farmer, or, indeed, almost anyone but an academician. By every one of those tests, I’d prove myself a moron, and I’d be a moron too.
