>They conclude that high IQ (>170) is mostly not caused by genetic variants.
The abstract does not mention that; they claim:
"This study shows the utility of extreme trait selection for genetic study of intelligence and suggests that extremely high intelligence is continuous genetically with normal-range intelligence in the population."
I don't think anyone would seriously claim that high IQ is mostly not caused by genetic variants, given the prior knowledge of the heritability of IQ.
