Nature Beats Nurture

From Vox Populi: Genetic science is not only destroying the last 50 years of educational policy, but social policy in general. The fact that up to 65 percent of the difference in academic results are genetic also explains why the post-1965 and post-1986 waves of immigration are destined to reduce the USA to Second World status:

Genes influence academic ability across all subjects, latest study shows 

The researchers analysed genetic data and GCSE scores from 12,500 twins, about half of whom were identical. Results in all subjects, including maths, science, art and humanities, were highly heritable, with genes explaining a bigger proportion of the differences between children (54-65%) than environmental factors, such as school and family combined (14-21%), which were shared by the twins.

Comparing the outcomes for identical twins with fraternal twins allows scientists to investigate the extent to which genetics influence a person’s life. Identical twins share 100% of their genes, whereas fraternal twins share on average only half of the genes that differ between people.

So if genetics were a significant factor governing GCSE results, the differences between fraternal twins’ performances would be expected to be consistently greater than those between identical twins – and this is what the scientists saw.

When the scientists factored in IQ scores, they found that intelligence appeared to account for slightly less than half of the genetic component, suggesting that other heritable traits – curiosity, determination and memory, perhaps – play a significant role.

Kaili Rimfeld, who led the study and is also at King’s College London, said: “There’s a general academic achievement factor. Children who do well in one subject tend to better in another subject and that is largely for genetic reasons.”

Plomin said that while talking about genetics and education was no longer the taboo that it was twenty years ago, education professionals were slow to adapt teaching methods in the face of new scientific findings. “It’s a problem with evidence,” he said. “Thirty years ago medicine wasn’t particularly evidence-based. I think education is fundamentally not based on evidence. What programme has been rolled out that has been based on evidence?

The “Blank Slate” theory is dead. It was never anything but political philosophy and science killed it. Every nominal justification for human equality is being gradually eliminated, one by one, as scientists revisit hypotheses that have long been passed off as pseudoscientific facts.
