That is simply not true at all. Despite the sanctions and taboos against looking for them alleles for intelligence and crime are being discovered.

Those with the genes were 13 times more likely to have a history of repeated violent behaviour.
The authors of the study, published in the journal Molecular Psychiatry, said at least 5-10% of all violent crime in Finland could be attributed to individuals with these genotypes.

Researchers have identified over 1,016 specific genes associated with intelligence, the vast majority of which are unknown to science.
An international team conducted a large-scale genetic association study of intelligence and discovered 190 new genomic loci and 939 new genes linked with intelligence, significantly expanding our understanding of the genetic bases of cognitive function.
Led by statistical geneticist Danielle Posthuma from Vrije Universiteit Amsterdam in the Netherlands, the researchers performed a genome-wide association study (GWAS) of almost 270,000 people from 14 independent cohorts of European ancestry.
All these people took part in neurocognitive tests that measured their intelligence, and when researchers contrast their scores with variations in the participants' DNA – called single nucleotide polymorphisms (SNPs) – you can see which mutations are associated with high intelligence.
From over 9 million mutations detected in the sample, Posthuma's team identified 205 regions in DNA code linked with intelligence (only 15 of which had been isolated before), and 1,016 specific genes (77 of which had already been discovered).

Quite apart from the growing body of genetic evidence for hereditarianism and race realism, it has long been known that intelligence runs in families. Teachers have long known that some students learn faster and with less effort than other students, and that those in the first group can learn what those int he second group cannot learn.
Head Start and No Child Left Behind have failed to close or even narrow the race group in academic performance.
No one has ever devised a method for significantly and permanently rising IQ scores.
