Most Reported Genetic Associations with General Intelligence Are Probably False Positives
This article from the Chronicle of Higher Education, reprinted on the American Renaissance site, attempts to explain the above paper. The author leaves considerable confusion over the nature of intelligence, possibly inviting egalitarian social scientists and their disciples to try to reassert their outdated belief that that intelligence is determined by environment and that all we really need to close the race gap is more money and less racism.
The actual study leaves no doubt. Here are some golden quotes for quick reference in case the subject comes up.
"General intelligence (g) and virtually all other behavioral traits are heritable." (very first sentence)
"General cognitive ability, or g is among the most heritable behavioral traits."
"The results reported here illustrate (...) the failure—so far—to find specific molecular variants that account for the substantial genetic influences identified by twin and family studies."
Explanation of the Study
What was disproved was not the connection between genetic factors and intelligence, what was called into question was the relation of specific single-nucleotide polymorphisms to intelligence. SNPs are one specific kind of variation in DNA. The study proposes other genetic type determinants of intelligence, citing a paper that shows a connection between variations in gene group (chromosome) structure. (The particular study cited went so far as to separate whites from others and show that whites are different!)
This is similar to the trait of height. The study points out that no specific SNPs have been tied to height, either.
"Height is approximately 90% heritable in Western populations, but so far no common variants contributing more than 0.5cm per allele have been discovered."
Nobody disputes that tall people have tall kids. Smart people have smart kids, too, and that's the overwhelmingly accepted view in microbiology. Common sense is vindicated by science once again!
