IQ, Algernon, and Introspection

Mankiw's Wish List... The Upside of Asia...

There are a lot of people who take offense at the idea that people have different levels of intelligence - and even at the idea that something called "intelligence" exists. As with most controversial issues, more data is unlikely to change their minds. Since they find the starting point objectionable, even a mountain of evidence seems to beg the question.

But perhaps the problem is that critics need a different kind of evidence. While on vacation, I came across one of my favorite childhood stories, "Flowers for Algernon," by Daniel Keyes, and frankly it's a more convincing brief for the reality of intelligence than a dozen of the best journal articles. "Flowers for Algernon" is written in the first person by Charlie Gordon, a mentally retarded janitor. The hook is that he gets experimental surgery that gradually raises his IQ up to the genius level. With each entry in Charlie's diary, we witness his mental development.

Here's how the story starts:

Dr. Strauss says I shud rite down what I think and every thing that happens to me from now on. I dont know why but he says its importint so they will see if they will use me. I hope they use me. Miss Kinnian says maybe they can make me smart. I want to be smart. My name is Charlie Gordon. I am 37 years old. I have nuthing more to rite now so I will close for today.

A few weeks after his IQ-enhancing operation, Charlie retakes an inkblot test:

[The tester said] "What do you see on this card? People see all sorts of things in these inkblots. Tell me what it might be for you - what it makes you think of."

I was shocked. This wasn't what I had expected him to say. "You mean there are no pictures hidden in those inkblots?"

He frowned and took off his glasses. "What?"

"Pictures. Hidden in the inkblots. Last time you told me everyone could see them and you wanted me to find them too."

He explained to me that the last time he had used almost the exact same words he was using now.

Here's Charlie around the time his IQ peaks:

I have often reread my progress reports and seen the illiteracy, the childish naivete, the mind of low intelligence peering from a dark room through the keyhole at the dazzling light outside. I see that even in my dullness I knew I was inferior, and that other people had something I lacked - something denied me. In my mental blindness, I thought it was somehow connected with the ability to read and write, and I was sure that if I could get those skills I would automatically have intelligence too.

Yes, it's fiction. In fact, it's science fiction - the short version won the Hugo Award and the long version won the Nebula Award. But what makes it great fiction is its psychological realism. Keyes captured what different levels of intelligence feel like. As I've argued before, we dismiss this kind of evidence at our own peril.

I had to read this book in my freshman AP English course. I didn't figure it as science fiction, however, but I guess it would be because we don't have technologies that can increase a person's IQ (yet). The only disagreement I do have is that those who are enthused with IQ scores and tests ignore other possible forms of intelligence and that IQ does not have to entirely be academic.

Jeremy writes:

Maybe not as many are offended with the existence of differential levels of intelligence as you think. I know many people, including me, who object to how it is defined today. I don't think studies about intelligence should be censored or banned but some humility and caution should be exercised by IQ proponents considering how much we don't know.

If you liked this, you might also enjoy, "The speed of dark" which deals with a similar question for autistics.


Matthew Cromer writes:

Yes there is definitely a difference between being high-IQ and not.

Low IQ people read something like this ( ) and they might actually take it at face value, while high IQ people are way too smart to be taken in by such "obvious nonsense" (see: )

PS - your comment windows are not allowing normal URL posting, so my comment is a lot more awkward than I had intended as I cannot inline the links.

One of my favorite Simpsons episodes, "Crayon in the Brain", is an homage to Flowers For Algernon, in which Homer briefly becomes as smart as Lisa. It even includes a smart rat. If you haven't seen it, you should.

Homer: Why am I sad, Lisa? I thought being smarter would make me happy.
Lisa: Oh, not at all. Look, I've graphed the relationship between intelligence and happiness [shows a graph where as intelligence goes up, happiness goes down]. (chuckles). I make a lot of graphs.

Current intelligence tests definitely cover a narrow range. For a theory of IQ testing that can cover everything from a dust mite to a Matrioshka Brain see the following links where intelligence testing meets complexity theory:

"There are a lot of people who take offense at the idea that people have different levels of intelligence - and even at the idea that something called "intelligence" exists": but it's all talk. When it comes to finding a doctor, a lawyer, an accountant or indeed a spouse for their offspring, do they act as if they don't believe in intelligence? To ask the question is to answer it.
