No, intelligence is not like height

What Is Intelligence, Anyway?

By Isaac Asimov

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?

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.

In a world where I could not use my academic training and my verbal talents but had to do something intricate or hard, working with my hands, I would do poorly.

My intelligence, then, is not absolute but is a function of the society I live in and of the fact that a small subsection of that society has managed to foist itself on the rest as an arbiter of such matters.

Consider my auto-repair man, again.

He had a habit of telling me jokes whenever he saw me.

One time he raised his head from under the automobile hood to say: "Doc, a deaf-and-mute guy went into a hardware store to ask for some nails. He put two fingers together on the counter and made hammering motions with the other hand.

"The clerk brought him a hammer. He shook his head and pointed to the two fingers he was hammering. The clerk brought him nails. He picked out the sizes he wanted, and left. Well, doc, the next guy who came in was a blind man. He wanted scissors. How do you suppose he asked for them?"

Indulgently, I lifted by right hand and made scissoring motions with my first two fingers.

Whereupon my auto-repair man laughed raucously and said, "Why, you dumb jerk, He used his voice and asked for them."

Then he said smugly, "I've been trying that on all my customers today." "Did you catch many?" I asked. "Quite a few," he said, "but I knew for sure I'd catch you."

"Why is that?" I asked. "Because you're so goddamned educated, doc, I knew you couldn't be very smart."

And I have an uneasy feeling he had something there.

Autobiography by Dr. Isaac Asimov (1920–1992): It's Been a Good Life

an hackernews:

a high correlation between intelligence and IQ

motherfuckers out here acting like "intelligence" is sufficiently well-defined that a correlation between it and anything else can be computed

intelligence can be reasonably defined as "knowledge and skills to be successful in life, i.e. have higher-than-average income"

eat a bag of dicks

Second, is the more common "IQ isn't intelligence" trick. Sure, the measure doesn't encompass everything that is making intelligence, but it is still a somewhat interesting proxy as there is a high correlation between intelligence and IQ.

Any time you see something like this, what it’s really saying is:

IQ is intelligence to me and nothing you say can dissuade me. I just have a high enough IQ to write a disclaimer for plausible deniability.

Imagine being a skilled San Francisco-style tech worker, at the apex of your industry, and the heights of intellect and rigor you can scale outside of that very specific context turn out to be "race science" apologia. Probably a lesson in there somewhere.

I knew this was good stuff when the majority of HN commenters where huffily complaining about the tone.

I want to make a HN account and reply to the 'depression and schizophrenia is or isn't a hardware/software issue' posters and tell them there is actually is a working IQ test, and they all just failed it.

In particular, two semantic tricks are used. First, the fact that current genetic markers aren't a good prediction for IQ heritability is used as an argument against it. The other likely explanation that our understanding of those markers is widely incomplete is not explored.

Unlike our understanding of IQ, the game of matching shapes where the loser gets a teen pregnancy. That's been fully explored.
