Charles Murray posted three articles this week on Education and Intelligence, a series that generated some conversation around the net:
- Intelligence in the Classroom:
Our ability to improve the academic accomplishment of students in the lower half of the distribution of intelligence is severely limited. It is a matter of ceilings. Suppose a girl in the 99th percentile of intelligence, corresponding to an IQ of 135, is getting a C in English. She is underachieving, and someone who sets out to raise her performance might be able to get a spectacular result. Now suppose the boy sitting behind her is getting a D, but his IQ is a bit below 100, at the 49th percentile.
We can hope to raise his grade. But teaching him more vocabulary words or drilling him on the parts of speech will not open up new vistas for him. It is not within his power to learn to follow an exposition written beyond a limited level of complexity, any more than it is within my power to follow a proof in the American Journal of Mathematics. In both cases, the problem is not that we have not been taught enough, but that we are not smart enough.
- What’s Wrong with Vocational School?
Begin with those barely into the top half, those with average intelligence. To have an IQ of 100 means that a tough high-school course pushes you about as far as your academic talents will take you. If you are average in math ability, you may struggle with algebra and probably fail a calculus course. If you are average in verbal skills, you often misinterpret complex text and make errors in logic.
These are not devastating shortcomings. You are smart enough to engage in any of hundreds of occupations. You can acquire more knowledge if it is presented in a format commensurate with your intellectual skills. But a genuine college education in the arts and sciences begins where your skills leave off.
In engineering and most of the natural sciences, the demarcation between high-school material and college-level material is brutally obvious. If you cannot handle the math, you cannot pass the courses. In the humanities and social sciences, the demarcation is fuzzier. It is possible for someone with an IQ of 100 to sit in the lectures of Economics 1, read the textbook, and write answers in an examination book. But students who cannot follow complex arguments accurately are not really learning economics. They are taking away a mishmash of half-understood information and outright misunderstandings that probably leave them under the illusion that they know something they do not. (A depressing research literature documents one’s inability to recognize one’s own incompetence.) Traditionally and properly understood, a four-year college education teaches advanced analytic skills and information at a level that exceeds the intellectual capacity of most people.
- Aztecs vs. Greeks:
How assiduously does our federal government work to see that this precious raw material is properly developed? In 2006, the Department of Education spent about $84 billion. The only program to improve the education of the gifted got $9.6 million, one-hundredth of 1% of expenditures. In the 2007 budget, President Bush zeroed it out.
But never mind. A large proportion of gifted children are born to parents who value their children’s talent and do their best to see that it is realized. Most gifted children without such parents are recognized by someone somewhere along the educational line and pointed toward college. No evidence indicates that the nation has many children with IQs above 120 who are not given an opportunity for higher education. The university system has also become efficient in shipping large numbers of the most talented high-school graduates to the most prestigious schools. The allocation of this human capital can be criticized–it would probably be better for the nation if more of the gifted went into the sciences and fewer into the law. But if the issue is amount of education, then the nation is doing fine with its next generation of gifted children. The problem with the education of the gifted involves not their professional training, but their training as citizens.
We live in an age when it is unfashionable to talk about the special responsibility of being gifted, because to do so acknowledges inequality of ability, which is elitist, and inequality of responsibilities, which is also elitist. And so children who know they are smarter than the other kids tend, in a most human reaction, to think of themselves as superior to them. Because giftedness is not to be talked about, no one tells high-IQ children explicitly, forcefully and repeatedly that their intellectual talent is a gift. That they are not superior human beings, but lucky ones. That the gift brings with it obligations to be worthy of it. That among those obligations, the most important and most difficult is to aim not just at academic accomplishment, but at wisdom.
