Intelligence and How to Get It

Thursday, May 7th, 2009


This book was recommended by one of the economist blogs that I frequent. The author is a cognitive psychologist who bristles at the concept that 75% to 80% of intelligence is inherited. For all of the faults of the book, he gives very good data against this. The numerous problems in the book include:

  1. Reliance on IQ tests. Yes, Dr. Nisbett is very clear that IQ tests aren’t really numerical intelligence scores, though since they do track with individual’s incomes and perceptions of how smart another person is, (to say nothing of the fact there is no alternative) they are used here whilly nilly.
  2. In the second and third chapters, he closely tracks the data. He shows where the 75% to 80% figure comes from (separated identical twins) and why the data is wrong (selection bias of adopting families). This is the best part of the book.
  3. Unfortunately to flesh this to a book-sized document, he continues with three chapters of racial bias/statistics: IQ and Black Americans, IQ and Asian Americans, IQ and European Jews living in the US. None of these chapters hone closely to the numerical data, and are instead a patchwork of anecdotes and unsupportable conclusions (Asians are better because of their Confucian background, etc.). I’d like to applaud him for at least broaching this subject, but I think he steers too far away from hard data for it to be useful. (Personally, I’m with Jared Diamond on this – there is almost certainly no major racial difference in intelligence or, if there is, the New Guinea Highlanders are way more likely to be the smarter than educated Europeans or Americans – see Guns, Germs and Steel or The Third Chimpanzee.)

I’d hoped for a more closely defended book, though the first three chapters are really quite good. A moderate recommendation from me at best. I can boil it down to a simple phrase for you: “Intelligence (as defined by IQ testing) is somewhat hereditary, but not to a level higher than 50% of the final attained score. Health (prenatal, perinatal, and juvenile), education, home environment, extended environment and the like account for the other parts. Heredity may be much less than 50% of the factor involved.”

The reason I’m blogging this here (I don’t normally comment on mediocre books that I read, there are too many of them) is that the author discussed home environments of high-IQ families vs. medium-IQ families. He mentioned that not only do high-IQ families read to their children, but they also participate in discussions. Hmm.

I normally just read to the kids. I make a big show of it – lots of voices, making myself quiet or very loud, jumping when there is a lot of action, etc. But I never really talked much about the books afterwards.

Two nights ago, I was reading the Cat in the Hat to all three. Afterward, I asked if the Cat was a good person or a bad person. That was the only question that I had to ask. It’s like they’d been waiting for all these years for a chance to talk about the Cat in the Hat, but hadn’t had a chance to do it.

They went on for fifteen minutes about characters, who was bad, who was good, what they would or wouldn’t do. You couldn’t stop them. And I didn’t want to. It was a very educational moment. For me.

Funniest Moment on TV – Lost

We watched this three times on our DVR last night. It was so funny …

Daniel is 6

Monday, May 4th, 2009


Today, Daniel Solon Steussy is six years old. Above is a photo from face painting yesterday at the San Diego Wild Animal Park. Below, it is one from a Friday trip to the new mall in Temecula. He’s showing off a drawing of the solar system.


According to his teacher, Daniel is excelling in his reading skills. His math is constantly surprising. At dinner yesterday, he clearly demonstrated a knowledge of odd and even numbers. His school paperwork shows addition of four digit numbers and subtractions using two digit numbers. Dad’s very happy.

Help Wanted

We need help. The girl we had counted on for the last year just emailed to say that she would not come. This puts us in rather a bind. Any ideas?

Baby number four is coming August 6.

I’ve joined Twitter. You can find me by searching for Ed Steussy. I don’t say anything interesting there: comments on Pappy, jogging, kids, the weather and the like. But if you want to know what I am doing this very minute, follow my Twitter.
