In the late 1990s, scientists thought they were close to locating specific genes that controlled for human intelligence in all its manifestations: musical genius, analytical acumen, physical prowess, etc. But the truth turns out to be more complicated, says Harvard psychologist and linguist Steven Pinker. There are many genes — perhaps thousands — that affect human intelligence, and while manipulating them may have predictable benefits, the adverse consequences remain unpredictable. Thus experimenting with our so-called intelligence genes will likely be met with high levels of skepticism in caution. It's proof, says Pinker, that technological advancement doesn't always march to the drum beat of inexorable forward progress.
