RE: Genetic and Environmental Contributions to IQ in Adoptive and Biological Families with 30-Year-Old Offspring

Dismal result for environmentalists.

Environmentally mediated effects of parental IQs, sibling-specific shared environment, and gene-environment covariance accounted for 8% of the IQ variance in adulthood. The heritability was estimated to be 0.42 [95% CI 0.21, 0.64]. Together, these findings provide further evidence for the predominance of genetic influences on adult intelligence over any other systematic source of variation.

This explains why Head Start and No Child Left Behind failed to close the race gap. Nevertheless, liberals continue to pretend that more white dollars will create more black scholars. The fact that they try to suppress the findings and assertions of heriditarians and race realists tells me that they do not believe their propaganda. If they wee really confident that the right environment (controlled of course by them) would improve black academic performance they would welcome a candid and honest debate on this topic.

Learning and intelligence depends on the BRAIN and how well a child can actually learn. White children have a genetic advantage based on a better brain and related upbringing. How many black children have parents who actually take an interest in their cognitive abilities and scholastic standing? My parents insisted I learn and learn what teachers taught. That lack of an education is equivalent to the "kiss of death" when as an adult, I'd be looking for a job or a career path.

Modern day social engineers will deny this newest study and double down on a myriad of useless, but costly, programs designed to raise the IQs of POCs.

If the brain cells simply aren't there, they aren't there.

It's been obvious throughout history that the brain cells aren't there. Just compare the white countries with the black countries. It's SO obvious!
