Significant new paper on the origins of IQ (although if I recall correctly, it confirms earlier results pointing to the same conclusion). It's from a group of international researchers with Robert Plomin the last named of about 25 on the paper. I'm talking, of course, about the nature-nurture question. The paper isn't brand-new, but I missed it when it came out last year. It's apparently still just available on-line.
>From the abstract (all I've read so far: "...common sense suggests that environmental influences increasingly account for individual differences in behavior as experiences accumulate during the course of life...We show for general cognitive ability that, to the contrary, genetic influence increases with age." "Why, despite life's "slings and arrows of outrageous fortune", do genetically dirven differences increasingly account for differences in general cognitive ability? We suggest...genotype- enviornment correlation: as children grow up, they increasingly select, modify and even create their own experiences in part based on their genetic propensities." So they think yo momma (or pop) had little to do with developing your smarts, as least as far as the way they brought you up. It was more your own genetic propensity to prefer PBS or the BBC to Fox, and Nova or Horizon to Jerry Springer. Haworth, C. and many others (2009). The heritability of general cognitive ability increases linearly from childhood to young adulthood.
