Is IQ Written in the Genes?

Well duh!  Only an imbecile or a slave of ideology could deny that genes exert a strong influence on cognition.

A recent study from King’s College London once again raises the issue of “the intelligence genes,” or specific genes that appear to be particularly influential in cognition.

An international team of scientists, led by King’s, analysed DNA samples and MRI scans from 1,583 healthy 14 year old teenagers.

The teenagers also underwent a series of tests to determine their verbal and non-verbal intelligence.

The researchers looked at over 54,000 genetic variants possibly involved in brain development.

They found that, on average, teenagers carrying a particular gene variant had a thinner cortex in the left cerebral hemisphere, particularly in the frontal and temporal lobes, and performed less well on tests for intellectual ability.

The genetic variation affects the expression of the NPTN gene, which encodes a protein acting at neuronal synapses and therefore affects how brain cells communicate.

Their findings suggest that some differences in intellectual abilities can result from the decreased function of the NPTN gene in particular regions of the left brain hemisphere. _Telegraph

First of all, intelligence arises from the cooperative effect of many distinct gene clusters. But within the gene clusters which have particular effects on cognition, particular genes are likely to act as “orchestrators,” or pivot points for the action of the individual genes in the cluster.

This might give scientists the impression that such genes are “intelligence genes,” when in fact it is more likely the nature of the research tools themselves which highlight such genes.

It is a tragedy that society continues to be bogged down on the question of whether genetic variation accounts for the majority of variation in IQ, in a well-nourished and well-educated population. Only an obtuse subservience to ideology can account for the widespread inability of persons in government, media, academia, and activist groups, to acknowledge the important gene-based differences in the strengths and weaknesses of different breeding groups of humans.

Science is getting closer to being able to construct and introduce artificial chromosomes into human cells. The introduction of such chromosomes into cells goes far beyond the plodding “gene therapy” trials that are currently being attempted. A chromosome contains entire clusters of genes, with the potential for large numbers of gene actions and interactions.

Another promising new approach to genetic modification is CRISPR.

Editas Medicine, a new company co-founded by some of the leading scientists studying Cas9 aim to translate its genome engineering technology into a novel class of human therapeutics. These therapies are destined to make significant medical advances for people with genetic diseases including, but not limited to, Huntington’s disease, cystic fibrosis, and Alzheimer’s. Since modern sequencing technology has produced a massive amount of human genome sequences, mapping diseases to certain genomic coordinates is becoming faster and easier. With this valuable sequence information, the CRISPR/Cas9 system can simply be engineered to make positive changes in specific diseased DNA sequences and restore normal function.

The revolution in bioscience has barely begun. The promise is immense. The main danger to the human future is the political knuckle-dragging of government, media, and academia. Entire economies are on the verge of collapse from government malfeasance and mismanagement, and yet somehow modern humans have given governments the ability to veto the human future by handing control of science research and the application of science to government.

The best possibility for the future would be for humans to voluntarily divide themselves between those who opt for free action in a quasi-objective reality, and those who insist on a politically correct, Orwellian world of thought police and fascist government-corporate cronyism. But since the fascist cronies have control, it will require an exceptional effort by those who love freedom to carve a niche for themselves.

HFTB-PFTW. And be prepared to take advantage of the opportunities as they arise.

Your governments, universities, and popular cultures can be unutterably stupid, but you don’t have to be.

    Bs thread, Indians are the richest ethnic group on America, they Silicon Valley, 30% of NASA, the diamond exchange in Antwerp, their kids beat all the white and Asian kids in the Scripps Spelling bees, and India has a space program that reached Mars before China and Japan, with half the budget of NASA, plus they have the third largest military, with a lot of Forbes billionaires, plus throughout history, stuff like cataract surgery went from India to China, not the other way around, plus Buddhism started in India too.
