Don't forget genetics.

To have true equality we will need to bring genetic engineering to the masses. Human genetic augmentation seems criminally underfunded and over-restricted to me.

Everyone wants to not forget genetics. No one wants to admit the inadequacy of their models of heritability of cognitive function in explaining disparities in educational outcome. Should we continue to judge the entire country solely on studies that claim 60-70% genetic influence (on cohorts of exceedingly similar European-descended subjects)? Twin studies that fail to consider epigenetic influence, widespread psychological effects, etc.? Studies that cannot take into account disparities in environmental effects, because they were unknown or exceedingly difficult to quantify?

If we find that there are significant, genetically-controlled disparities, how do you suppose we go about treatment? We can't even treat SNP-based disorders yet. Cognitive function is controlled by the complex interaction of multiple genes.

I'm sorry for the cynical response. I'm just annoyed that this approach seems to come up constantly, despite the problem being unproven and the solution not efficacious. As a society, provide people with safe, stable homes and communities, their children with equal education and development-centered nutrition and activity, and keep going for a generation or two while we increase our sophistication with genetic and heritability science. Then we can talk about where differences may lie and how, if at all, to treat them.

Obviously heritability figures are time-and-place specific and safe and stable homes (with good nutrition) are vital for success.

But even if the IQ (yes, I can hear the collective groan, but keep reading) difference between a Nigerian and a South Korean is 0% genetic, the within-group differences are still a good 20 points, half of which a genetic engineering program might be able to fix.

We're a long way from being able to do this admittedly, which is why funding and less restrictions would help, but I believe the QALY gains from success would be huge.

Btw: If it does turn out that womb environment is the killer app, the government should try and encourage a massive surrogacy campaign (allowing payment if it doesn't already).
