Summary:

Scientists have made a major advance in understanding the genetic underpinnings of intelligence. Using a large dataset of more than 78,000 individuals with information on DNA genotypes and intelligence scores, the team discovered novel genes and biological routes for intelligence.

Intelligence is one of the most investigated traits in humans and higher intelligence is associated with important economic and health-related life outcomes. Despite high heritability estimates of 45% in childhood and 80% in adulthood, only a handful of genes had previously been associated with intelligence and for most of these genes the findings were not reliable. The study, published in the journal Nature Genetics, uncovered 52 genes for intelligence, of which 40 were completely new discoveries. Most of these genes are predominantly expressed in brain tissue.

      Amazing that regardless of wealth or political system some countries give similar results. For example North Korea scored at 106 on average and South Korea did the same 106. And that is among the absolute top of the world. 
      So for a good society average high IQ in it self does not guarantee that. High IQ is useful for solving tasks. But if an evil person has high IQ, then he can do much damage. I would say that a kind person with low IQ is better than an evil person with high IQ.
      We are all members of the same body as the Bible says and every type of person can be valuable for the society and for God.
