Another study, uncovered three genetic variants associated with extremely high IQ scores. “It’s important when doing this work on behavior & genetics to be aware of the really negative history of misuse and misinterpretation of research in this area; there is evidence that when selection for intelligence is poised as a matter of choice or prevention, the public becomes rather accepting. Maybe we’ll dive into the genome anyway, chasing every last advantage we can wring from the science. Or maybe as we apply our cognitive skills to the painstaking project of understanding those very skills, we’ll find other ways to sharpen minds.'
