DNA tests can predict intelligence, scientists show for first time

DNA tests can predict intelligence, scientists show for first time. By Sarah Knapton.

Intelligence could be measured with a swab of saliva, or drop of blood, after scientists showed for the first time that a person’s IQ can be predicted just by studying their DNA.

In the largest ever study looking at the genetic basis for intelligence, researchers at the University of Edinburgh and Harvard University discovered hundreds of new genes linked to brain power.

Now by studying the genetic data from more than 240,000 people, scientists have found 538 genes which are linked to intelligence. …

Dr David Hill, of the University of Edinburgh’s Centre for Cognitive Ageing and Cognitive Epidemiology (CCACE) who led the research, said: “Our study identified a large number of genes linked to intelligence. “We were also able to predict intelligence in another group using only their DNA.” …

But the new research suggests that intelligent people are biologically fitter. …

Steve Sailer:

Not sure this is “the first time” because it’s of course a question of how much IQ can be predicted. …

Presumably, a lot of IQ variation is less due to having genes that are better, on paper, at generating higher IQ and instead are due to having fewer important genes that are broken due to unfortunate mutations (which may have negative consequences for both brain and body).

Over in the “social sciences”, a few more heads are blowing up as they hang onto their self-serving theories for dear life. Another “it’s-a-social-construct” meme hits the fan.
