The study, published in the prestigious peer-reviewed journal the Lancet, began with 5,914 newborn babies in 1982, and were able to follow up with 3.493 of those individuals three decades later.

Superhuman intelligence: the new Cold War?

In my last blog posting, I explained how the body of academic literature on human intelligence is increasingly clear: IQ tends to be largely inheritable, with 60% of IQ variability explained by genetic factors. I also introduced recent research at US San Francisco which highlighted the ‘VS’ variant of a gene called KL. The VS …

Superhuman intelligence

Intelligence or IQ is more deeply rooted in genetics than it is in environment factors or upbringing. This is what researchers at Kings College London have found that genetics explain more than 60% of the variability in IQ test results. The nature vs nurture debate is clear: nature wins. This finding may explain why several prior studies have …

National IQ scores

The intellectual quotient or IQ provides a measure of one’s intellectual ability or intelligence. The IQ score was first invested by Frenchman Alfred Binet in the last 1800s, as means to identify and remove less intelligent Parisian children who might be slowing the progress of their more intelligent classroom peers.  So the question of intellectual ability …
