The New York Times just published an op-ed by a Michigan State University professor named David Z. Hambrick, “I.Q. Points for Sale, Cheap,” that says nothing about race, but which is all about race.
Hambrick has me very confused. He says, “Until recently, the overwhelming consensus in psychology was that intelligence was essentially a fixed trait.”
I thought the “intelligence as fixed trait” position was that of evil racists like Arthur Jensen, Richard Lynn, Richard Herrnstein, J.P. Rushton, Linda Gottfredson, Charles Murray, et al., while all enlightened minds said that intelligence was plastic, and determined by one’s environment.
Hambrick:
Why the craze? Until recently, the overwhelming consensus in psychology was that intelligence was essentially a fixed trait. But in 2008, an article by a group of researchers led by Susanne Jaeggi and Martin Buschkuehl challenged this view and renewed many psychologists’ enthusiasm about the possibility that intelligence was trainable — with precisely the kind of tasks that are now popular as games….
Why would serious scientists be bowled over by one lousy article?
Does this sound like an extraordinary claim? It should. There have been many attempts to demonstrate large, lasting gains in intelligence through educational interventions, with few successes. When gains in intelligence have been achieved, they have been modest and the result of many years of effort….
We shouldn’t be surprised if extraordinary claims of quick gains in intelligence turn out to be wrong. Most extraordinary claims are. But we shouldn’t be totally discouraged, either. Results of studies like the Abecedarian project suggest that intelligence can be increased by making improvements in people’s environments, and that this can improve people’s lives.
But such studies also suggest that meaningful increases are not likely without a substantial commitment of resources. If we lose sight of this fact, this is a commitment we may never make.
Socialists and communists have argued for 100 years or so that if you changed dullards’ environment, you could turn them into rocket scientists. Over $170 billion has been seized from white taxpayers so far, and poured into Head Start, whose black (and later black and Hispanic) charges used to show initial gains… which were all lost at later ages. But now, children in Head Start show no gains at all, and even some losses.
In other words, no taxpayer-financed program, at no cost, is cognitively superior to Head Start.
It is the backdrop of the religious zeal for improving the intelligence of blacks, by people who otherwise keep telling us that race does not exist, and that g does not exist, that explains how all of these “scientists” would suddenly become born again intelligence improvers… as long as it the zealotry is pursued with the money of other people, from a race they condemn, when they aren’t denying it exists.
But what if the “experts” were to consistently acknowledge the existence of race and g, respectively, and actually found a method guaranteed to permanently increase the intelligence of black children?
It would still be a no-go. First, because hundreds of millions of whites already gave at the office. The government simply has no right to seize any more hard-earned wealth from a race that it has spent 50 years pauperizing, no matter how well-intentioned the purpose.
Second, even if the method were a slam-dunk, it would still be a waste, because black supremacist poverty pimps would insist on “controlling” it, which is to say, robbing it blind, just as they have seized control of, and plundered all black-oriented welfare-programs since the Johnson Administration.
(P.S. Note that black nationalists. e.g., my old York College colleague, Chuck Coleman, have denied that black children have any deficit that is in need of remediation. That position denies the basis for all such programs though, oddly enough, the folks denying their basis have never called for them to be shut down.)
There’s a dirty little secret, when it comes to black children: The only identifiable group that cares about helping them is white folks. Blacks who claim to be devoted to black children (“the children are the future”) only care about using them to pick whites’ pockets, and to train those children to be soldiers in a now 50-year-long race war.

I.Q. Points for Sale, Cheap
By David Z. Hambrick
May 5, 2012
A STRIKING trend in today’s culture is the pursuit of rapid cognitive enhancement. The idea behind many popular video and online “brain-training” games is that practicing tasks that strengthen memory, attention and other mental processes will make you a smarter person.
Nintendo markets its Brain Age game as a “treadmill for the mind.” Lumosity, which claims 20 million users, says that its brain-training games offer “real-world cognitive benefits in individuals of all ages.” Cogmed, which has been adopted by schools in the United States and Sweden, helps its users “unlock their natural cognitive abilities by training their brain.” Forbes magazine recently declared cognitive enhancement the next “trillion-dollar industry.” The United States military is even exploring the possibility of using such cognitive training to increase soldiers’ capacities.
Why the craze? Until recently, the overwhelming consensus in psychology was that intelligence was essentially a fixed trait. But in 2008, an article by a group of researchers led by Susanne Jaeggi and Martin Buschkuehl challenged this view and renewed many psychologists’ enthusiasm about the possibility that intelligence was trainable — with precisely the kind of tasks that are now popular as games.
Yet I and many other intelligence researchers are skeptical of this research. Before anyone spends any more time and money looking for a quick and easy way to boost intelligence, it’s important to explain why we’re not sold on the idea.
In the Jaeggi study, the researchers began by having participants complete a test of reasoning to measure their “fluid” intelligence — the ability to draw connections between things, solve novel problems and adapt to new situations. Then some of the participants received up to eight hours of training in a difficult cognitive task that required paying careful attention to two streams of information (a version of this task is now marketed by Lumosity); others were assigned to a control group and received no such training. Then all of the participants took a different version of the reasoning test.
The results were startling. The authors reported that the trained participants showed a larger gain in the reasoning test than the control group did, and despite the relatively brief period of training, this gain was large enough that it would be expected to substantially improve performance in everyday life.
Does this sound like an extraordinary claim? It should. There have been many attempts to demonstrate large, lasting gains in intelligence through educational interventions, with few successes. When gains in intelligence have been achieved, they have been modest and the result of many years of effort.
For instance, in a University of North Carolina study known as the Abecedarian Early Intervention Project, children received an intensive educational intervention from infancy to age 5 designed to increase intelligence. In follow-up tests, these children showed an advantage of six I.Q. points over a control group (and as adults, they were four times more likely to graduate from college). By contrast, the increase implied by the findings of the Jaeggi study was six I.Q. points after only six hours of training — an I.Q. point an hour.
Though the Jaeggi results are intriguing, many researchers have failed to demonstrate statistically significant gains in intelligence using other, similar cognitive training programs, like Cogmed’s. The Web site PsychFileDrawer.org, which was founded as an archive for failed replication attempts in psychological research, maintains a Top 20 list of studies that its users would like to see replicated. The Jaeggi study is currently No. 1. While this is an indication of the interest among psychologists in the idea that cognitive training might produce remarkable gains in intelligence, it also reflects a widespread cautiousness toward the results of a single study.
Another reason for skepticism is a weakness in the Jaeggi study’s design: it included only a single test of reasoning to measure gains in intelligence. As the cognitive psychologists Zachary Shipstead, Thomas Redick and Randall Engle note in a recent review of the cognitive training literature in Psychological Bulletin, intelligence can’t be measured with any single test; it reflects what tests of many cognitive abilities have in common. Demonstrating that subjects are better on one reasoning test after cognitive training doesn’t establish that they’re smarter. It merely establishes that they’re better on one reasoning test.
We shouldn’t be surprised if extraordinary claims of quick gains in intelligence turn out to be wrong. Most extraordinary claims are. But we shouldn’t be totally discouraged, either. Results of studies like the Abecedarian project suggest that intelligence can be increased by making improvements in people’s environments, and that this can improve people’s lives.
But such studies also suggest that meaningful increases are not likely without a substantial commitment of resources. If we lose sight of this fact, this is a commitment we may never make.

The old saying: If you give a million monkeys a million typewriters and a million years, you get Shakespeare.
Then again, if you give on Elizabethan-era Englishman and quill pen and fifty-two years, you also get Shakespeare.
If you want Shakespeare, which option do you choose?
